Abstract: 248,074. Hausmann, M. Nov. 27, 1924. No Patent granted (Sealing fee not paid). Respirators.-A pressure-compensating device for use in respiratory apparatus comprises two impervious flexible bags held in contact in a rigid container through which the breathing gas flows, one of the bags communicating with the atmosphere and the other with the exhaling tube. As shown in the Figure, one impervious bag l is fixed in the upper wall of a rigid container a and communicates with the atmosphere through apertures p. The other bag k is secured to the wall of a passage z into which the exhaling tube d from the mask f opens, the interior of the bag k communicating with the passage z. Breathing gas introduced into the container a from a cylinder o through a pressure-reducing valve r is inhaled through the tube e and on exhalation passes through the passage z partly into the bag k and partly through the purifying cartridge i back into container. The partial vacuum created on inhalation is compensated by the entry of atmospheric air into the bag l, the inflation of which compresses the bag k and forces gas therefrom through the cartridge i. On exhalation, the process is reversed, the bag k becoming inflated, as shown in the Figure, and causing the bag l to collapse.

Title: Improvements relating to condenser systems in steam power plants
IPC: F01B25/00
Filed: 1921-10-29
Abstract: 188,515. Metropolitan - Vickers Electrical Co., Ltd., (Westinghouse Edectric & Manufacturing Co.). Oct. 29, 1921. Conveyer-apparatus, ejector.-A condensing steam-power plant is so arranged that water is normally withdrawn from the condenser by an ejector operated by low-pressure steam, such as the exhaust from partially-condensing auxiliaries at from 5 to 7 lbs. pressure, but that if this supply is insufficient, steam at higher pressure, such as the exhaust from non- condensing auxiliaries, and, if necessary, live steam are automatically supplied. In the arrangement shown water is withdrawn from the hot-well 11 of the condenser 10 by an injector 17 provided with an overflow 21 returning to the condenser and passed to a feed-water heater 29. Steam is supplied to the nozzle 16 of the injector 17 from the exhaust of the partially-condensing auxiliaries of the system through a pipe 12' and a conduit 14. Pipes 40, 42 communicating with the conduit 14 and the condenser 10 open into a cylinder 37 on opposite sides of a spring-controlled piston 38. If the pressure in the condenser rises a rod 28 attached to the piston 38 opens a valve 27 in a pipe 25 communicating with the exhaust of the non-condensing auxiliaries. If the pressure continues to rise the rod 28 operates a lost-motion device 33 which opens a valve 32 in a steam pipe 30. The live steam thus admitted drives a movable nozzle 35 against the inlet of the nozzle 16, thus cutting off the pipes 12 and 25, and operates the ejector 17 until the pressure in the condenser falls.
