Title: Improvements in and relating to apparatus for bringing liquids and gas or vapours or both gas and vapours into intimate contact
IPC: B01D47/06
Filed: 1929-04-03
Abstract: 331,818. Watson, S. G., Henshaw, D. M., and Holmes & Co., Ltd., W. C. April 3, 1929. Washers. - Apparatus for bringing liquids and gases into intimate contact, comprises a chamber divided by partitions 4 into communicating compartments each containing brushes 1 which are secured against rotation and associated with means to distribute water over them. The brushes are stationary or may be oscillated. Gas enters by valve 25 and pipe 23 into the chamber containing brushes 1 mounted on backings removably attached to both sides of vertical plates 2. The gas passes through apertures 33, 34 alternately at the top and bottom of partitions 4 in the chamber. Water is circulated by pumps from the base to sprays 14, which may be movable. The water passes by oxerflows 18 at different levels to a trapped outlet 19. The gas is delivered to a pipe 24 with a valve 26, or may pass without washing through a valve 30 and pipe 29. The gas may pass through an empty chamber 35 at each end of the brushes, and the holes in the partitions may be at the edges, guiding the gas from side to side. According to the Provisional Specification, rotary brushes may be used. Specifications 5113/95, 162,166, 275,092 and 283,028 are referred to.

Title: Process for the recovery of ammonia from used cuprammonium artificial silk precipitation liquors
IPC: C01C1/10
Filed: 1937-04-12
Abstract: <PICT:0493716/III/1> Ammonia is recovered from the waste cuprammonium precipitation liquors used in the manufacture of artificial silk, by passing the warm liquor through a countercurrent of steam having a pressure corresponding to the temperature of the liquor, and condensing the mixture of steam and ammonia.  The liquor enters the countercurrent apparatus 3 by a pipe 1 and meets the steam supplied through pipes 7 by evaporators 5a, 5b, into which the spent liquor from 3 passes.  The steam is drawn off from 5a, 5b by compressors fed with steam by pipes 71, and the mixture of steam and ammonia passes by pipe 8 to a condenser 9, and then to an absorber 10, cooled by fresh precipitation liquor fed thereto by pipe 19.  This heated fresh liquor passes by pipe 20 to the pipe 22 leading to the artificial-silk apparatus.  The ammonia solution may pass by a heat-exchanger 13 to a rectifying column 14 supplied with steam by a pipe 21 and leading to an end condenser 16.

Abstract: 527,254. Cylinders. DAIMLER-BENZ AKT.-GES. April 5, 1939, Nos. 10624 and 10625. Convention dates, April 5, 1938, and March 29, 1939. [Class 7 (ii)] In an arrangement for utilizing a cylinder for supplying compressed air for braking &c. a cylinder valve h is opened during the compression stroke when the pressure in the compressed-air supply reservoir m drops below a fixed valve. This allows a spring-pressed pump plunger r to follow an engine-driven cam u; fluid in a pipe o, e.g. lubricant, normally circulated by a sump pump, as shown past non-return valves n, w and through a plunger groove q is thus isolated and compressed at the required times to open the valve h. When the desired pressure in the reservoir m is the groove q again allows continuous lubricant circulation. Adjustment is effected by varying the spring-pressure acting on the plunger r; a safety valve z is provided. In a modification, the valve h is lifted directly by the cam u through an intermediate member, which is telescoped against a spring when the required pressure in the reservoir m is reached.

IPC: F02M7/133
Filed: 1925-04-27
Abstract: 257,313. Tice, P. S. April 27, 1925. Spray carburettors.-Fuel from a float chamber 22 is supplied through a restriction 26, Fig. 7, to a conduit 27 supplying a main nozzle 28 situated at the throat 20<c> of the choke tube 20, and through a restriction 50, Fig. 2, provided with a non-return ball valve, to a chamber 41a which communicates through conduits 45, 46, 47, Fig. 6, with an auxiliary fuel nozzle 48 opening nito the choke tube opposite the main nozzle. The wall of the chamber 41a consists of a piston 42 attached to a spring-loaded flexible diaphragm 43. Fuel is also admitted to the chamber 41<a> through a duct 53, a valve 56, and ports 54, when the valve seat 55, which is formed in a boss 42<a> carried by the piston 42, is moved away from the valve, the valve being restrained from following the seat by the engagement of an adjustable stop 64 with a pin 57 carried by the valve. Suction from the induction pipe on the engine side of the throttle valve 30 is transmitted to the outer side of the diaphragm 43 through a port 71, Fig. 9, conduits 72, 74, calibrated orifice 74<a> and recess 76. A slow-running nozzle 31, supplied with fuel from the main nozzle 28 through a valve-controlled conduit 35, is provided. During slow-running, the piston 42 is retracted by the high suction beyond the throttle, and fuel enters the chamber 41a through the restriction 50; when the throttle is opened, the increased pressure transmitted from the induction pipe causes a sudden forward movement of the piston and a jet of fuel is discharged through the nozzle 48. During normal running, however, the suction is still sufficient to hold the piston in such a position that the valve seat 55 engages the valve 56, but when the throttle is fully open under load the seat moves away from the valve, thus admitting additional fuel to the chamber 41a through the duct 53, the valve 56 and ports 54.
