A total of fifty buildings were destroyed. Iteny of these were small and are not Identified on the plan. Others, such as 37. 58 and 39 ware of good size. Since the bombing, many build- ings haye been repaired and new ones haye been built. The plant operated up to 1930, on 2 May 1945* at which time Allied Forces entered the town# It is interesting to note here some remarks of Dr# Draeger pertinent to that incident. *At the time I happened to be talking on the long distance telephone to a representative of Admiral Donitz in Travenamde# He was informing me not to destroy anything since the English and American troops were on their way# I told him that they had already arrived and I held the phone receiver out of the window so that he could hear the tanks rumbling by.* All buildings were examined by the investigators. Those of spec- ial interest were tnesei (1) The officca (2) The divers testroom (3) The to siroom for oxygen - supply apparatus (4) The oxygen tank room (5) The oxygen plant, work shop and magazine (6) The chemical laboratory and offices (7) The main chemical laboratory (8) The laboratory for low temperature (9) The test room for ventilation apparatus and for high pressure appliances (10) The store roans D# Operating Equipment The operating equipment of the plant was abundant and of tne high- est quality. It was fully commensurate with tne development and produc- tion of precision instruments for which the Draegerwerk enjoys a world- wide fame. E. Stocks of - The material stored In various magazine within the plan- consisted of large stools of raw material, incidental irts and various production items in all stages of development, from the rough to the finished product. The stocks of material incluued the follow:ng: (1) Rubber (2) Leather 13} brass (4) Plastics (5) Aluminium (small amount) (6; Steel forgings and castings The stores of incidental parts contained an abundance of general hardware such as screws, nails, nuts and bolts. There were also stores of machine tools, chemical glass ware, hanm r handles of all sizes, brushes, pails and an assortment of oi!ice supplies. The stocks of production items cons istea of finished t «rts and completely assembled iteno as listed in paragraph two of the report. Many of these items are described also in paragraph four and are the subject of various documents indexed in paragraph six. The magazines containing these stocks were located in the ground floor of buildings number 2 and number 7, also the basement and the 1st, 2nd and 3rd floors of building number 8. F. Subsidiary firms.

Noe. Stated to be a most successful unit. . An example has been brought to this country. The unit is numbered L200/U1. It was developed in DrAgpnrerk as a silent motor to circulate foul air through soda-line cartridges in S/Ms, Its delivery, indloated by its number, is ZOO cubic meters per hour at a pressure of 90 mm wat r. Sound level is 35-40 phones at 0.3 metre. Its success was such that the principle was used in the construction of main ventilation fans, which were simply larger versions, L1000/U1 delivering 1000 ou. mu per hour and 14000/ul, delivering 4000 ou. mu per hour. These larger versions were not sufficiently silent to enable them to dispense with L200/U1, which was installed in addition. 1200/Ul, having sucked air through the soda-line cartridges delivered straight into the main ventilation truhkix^. (7) Soda-Idne container. (Ref. No. 217). Drawings of this container. (8) 00o - Verdlohter 216. Ref, No. 216). This compressor, also used for 002 olearanoe and other purposes is an adaptation of a Swedish patent: Sohraubenradverichter, made by Pinna LJungstrflm Angturbin, Stockholm. It Is thought to be of the sane type as the Ins telemeter pumps fitted in British S/Ms. Dr. Meler-Vlndhorst was most enthusiastic about its possible applications, aneubetanoe; the lunps of silica-gel or of glass never became impregnated with a uniform layer of the pyridylium-violet; and finally because the pyridylium-violst was difficult to prepare. (b) Sodium hydrosulfate method* , In a small bottle of about 100 onr capacity, a solution of sodium faydrosulfate containing methy- lene blue as an indicator is shaken with a given amount of air* The hydrosulfate must be exactly weighed and brought into the bottle as & dry powder* D» time necessary for the oxydation of the hydrosulfate is a function of the oxygen percentage of the air tested* Knowing the measured time, the oxygen contents can be esti- mated with the help of an empirically drawn graph* Die temperature of the reaction-fluid must be controlled since it influences the rapidity of reaction* In a later development, the correct amount of hydrosulfate was introduced into small glass ampoules with thin walls* (o) Another method still in the developmental phase was also described as follows: A weighed amount of Pent&phenyloyolo- pentadienyl is impregnated on glass lunps by a process in which oxygen is avoided. Therefore a porous carrier would not be suitable. The impregnated glass lumps are placed in an evacuated ampoule of known volume, or in a glass tube containing an inert gas at normal pressure. A measured volume of the air to be tested is sucked through this tube by means of a pump. Color changes from deep violet to a slight yellow color depending upon the concen- tration of oxygen in the air. b. Umfullanlago (oxygen transfer system)* (Ref* Document No* 52;* o* Helium and Oxygen* The Germans wished to oarzy out experiments with a mixture of helium and oxygen but oould not do so because they were never able to obtain enough helium* (3) Ca1i30n-di03d.de. a* Dmger (meter). (rCef. document No. 21.) A meter of this typo was captured at the Submarine Medical Ho search Institute, Camac, France, as mentioned in a report of that investigation COMNAVKU OO65I over RNPL l/Wb» Furthermore, it is the subject of reports RNPL 6/45 and of TR/PG/lO%i/NID. It is sufficient to summarize here some of the criticisms of the meter recorded in the report by RNPL, They are as follows: (a) There is an error ranging from + to -3O/0 in the meter value obtained. (b) Considerable training Is necessary to operate the meter. (o) Oil from the manometer was sucked into the chamber for the gas sample, thus interfering with the analysis. b. Combined OOp and Op Indicator. (Ref, Document No. 260(1)). This instrument is the subject of report RNPL 6/45» page 14 which concerns an instrument discovered at Carnac, The origin of this instru- ment was not known at the time of that report. It is now ascertained that the instrument was made by the Dragerwerk to tfie order of Dr. ~«epol, the head of the Camac Institute who had seen the individual OO2 and 02 estimators labelled (l) and (2) in the first plate attached to the do cuius nt cited, Drager- werk knew nothing of the perfonnanoe of the combined estimator. They stated that it had been delivered to Camac just prior to evacuation of that Institute in 1914. This was but a few montns before our arrival in Camac to investigate the Institute.

The carbon monoxide indicator consists of a double acting, hand operated suction puxnp and a series of snail, unsealea glass tubes. The tubes contain silica-gel for absorption of hydrocarbon and Iodine pentoxide for the indicator* To obtain a quantitative Indication, ten strokes should be made with the punqp and then a color ccomparison with a standard chart to determine the quantity. b.

To compensate for the lack of the formerly used Mexphalt the following mixture was enployod. 30 parts of pitch (softening point 63° C.) 20 parts of tar (beginning to boil at 200° C). 30 parts of bolus alba 6 ports of sawdust The mixture has a softenirg point of 70° C and a boiling point (brittlirg) of - 5° C. H. Li a cell one oua. Anesthesia and inhalation apparatus. Principal contributors Dr. Ing Cordes and Eng.Joseph Hunt. (l) /Anesthesia and Inhalation -apparatus, (itef. Document No, 253). a. Introduction, The majority of this apparatus was designed and built before the war and hence no striking developments exist. oince in German medicine anesthetists are not specially trained for their Job, the machines have to be fool-proof. The three developments which deserve mention are: 1. the use of a heated plate for vaporization of the ether, to raise the temperature of the gas mixture at the mask. This decreases the chances of ill effects on the respiratory tract and decreases the severity of the after effects of narcos is. The plate is kept at a constant temperature of 60 C by an electrical heater. 2. The use of an aspirator to introduce liquid medicaments into the narcotic gas mixture. 3. 'The use of a water check valve and a filter on the exhalation side of the circuit to give an indication of breathirg and take out the ether not utilized. This prevents the accumulation of ether in the operating room. Another development is the use of conductive rubber on the wheels and tubes of anesthesia apparatus to prevent tin accumulation of static electricity, hleotric conductors to giound are also supplied to the machine and the operating table, b. Description, The description of the anesthesia and inhala- tion devices are adequately described in the literature on this subject, of which a list la included in this report. c. Comments. The engineer in this department, hng. Joseph Haupt, worked on a constant flow system for a Ju 52 for evacuation of wounded from .J’rica. He also developed the douche valve for the swim suit previously described. (2) braver Pulmotor. (Kef, Document No. 253)* This apparatus had a wide use for the treatment of carbon monoxide intoxication and for the resuscitation of drowned people. It was issued by the German Navy, The latest type pulmotor examined delivered both positive and pressure. The negative pi assure experienced by one of us was far too high fbr comfort. (3) therapeutic Oxygen. Interrogation disclosed that the Germans also had vivid discussions relative to the therapeutic use of oxygen. The principle of constant oxygen supply was finally chosen. This was based on experiments carried out by Prof. Flurry in Wdrzburg who showed that long inhalation of pure oxygen by animals was injurious. This effect had not been observed in healthy men, but there was considerable doubt regarding it in gassed cases. (4) Heat-producing preparation (cnemicaJ. heat) for heating tinned food.

The combustion is nearly smokeless. (5) Anti -Winning work. The chemical department was also engaged with the development of substances to maintain clear vision through aircraft cabins, and eye pieces of gas masks. Nothing was accomplished as far as aircraft is concerned For gas masks, however, an anti-dimming fluid was developed, manufactured and sold. This fluid has the following formula: 1. 30 kg Igepal C, high concentration 2. 50 kg Polyglykole 3# 50 kg ethyl or isopropyl alcohol 4* 1 kg Nekal Bx, dry The substances 1 aid 4 were supplied by I.G.

Master Drag or said "every effort had been made on life-saving rather than on life- . destroying ideas and apparatus"* Our investigation shows that this was rather a true statement* C. Research and development carried out by the firm was of the highest caliber* D. Prom a developmental point of view, their most inpressive accomplishment related to regulators, including the demand regulator* The investigators were increased by the width of the range of these regulators* Their accuracy is still to be verified, but if the general aooooplishnent of the firm is a good index they are good regulators* B. For the last year of the war very heavy emphasis had been placed on production of civilian gas masks and the general protec- tion of the civilian population. The Dragerwerk was charged with this responsi- bility* In this connection it is interesting to record a statement by Dr* Drager "We never intended to use gas because we were not prepared to receive it. We were of the opinion that people in glass houses should not throw stones”. P. In production, the only real difficulty experienced was the lack of robber* Other than this all their raw material seemed to be of the best quality* 0* The Germans appear to be well ahead of the Western Allies in air purification of submarines, especially in small craft, namely the one and two man U-boats* If their claims are correct, the silent motor described is superior to any we have thus far seen. H. It is interesting to note here that the Germans . had perfected a U-boat with a submerged speed of no re than 20 knots. Furthermore, they had designed a midget submarine capable of a reported underwater speed of about 60 knots. This was to be Jet propelled.
