Abstract: 341,080. Charging annealing-furnaces. EVANS, J., Plasvfedwen, Swansea Road, Pontardulais, Glamorgan. Oct. 8, 1929, No. 30502. [Class 51 (ii).] A machine for charging annealing-furnaces comprises a wheeled support 57 adapted to be rocked about the axis of the wheels 55 by a rearwardlyextending arm 54, and is propelled and guided by a trolley 5 driven by an electric motor 4 and fitted with a vertically and horizontally adjustable member 6 to which the arm 54 is coupled. The trolley 5 has front driving wheels 1 and a rear steering wheel 2, the drive being transmitted from the motor 4 by gearing 8 .. 11 to a shaft 12 carrying pinions 13 which mesh with pinions 14 secured to the inner sides of the wheels 1. Handoperated clutches 15 are provided for controlling the drive. The coupling-member 6 is carried by a block 31 adapted to be traversed in curved horizontal guides 29 by a chain 32 passing round idle sprockets 33 and a sprocket 34 loosely mounted on a vertical shaft 35. The latter is driven from the shaft 12 through gearing 17, 18, 20, 36, a clutch 37, 38, operated by a handle 44 through a pivoted lever 40 and strap 39, being provided to connect the sprocket 34 in the drive when it is desired to adjust the member 6 horizontally. The gears 18, 20 are formed integral with a sleeve 22 which is looselv mounted on a shaft 19 and carries a clutch-member 23 adapted to be engaged, when vertical adjustment of the coupling 6 is necessary, by a hand-controlled member 24 to drive the shaft 19. The latter carries toothed quadrants 26 which effect, vertical movement of racks 27 secured to the ends of the guides 29.

Abstract: 1314215 Removing acid gas from natural gas streams FISH ENG & CONSTRUCTION Inc 24 June 1970 [27 June 1969] 30736/70 Heading B1L [Also in Division C5] Natural gas containing CO 2 , H 2 S, COS and mercaptans is purified by first removing water by countercurrent contact with glycol in vessel 2, mixing the feed with rich solvent leaving absorber 10 by line 11 and with recycle gas leaving flash chamber 17, and passing the mixture to, and up through, absorber 10 in countercurrent to streams of solvent, e.g. a polyalkylene glycol dimethyl ether, at 400-1300 psi, the solvent streams entering by lines 55, 68. Purified gas passes through a glycol contactor 69, wherein solvent is recovered, and leaves for use by line 70. Rich solvent bottoms passes by line 14 to expansion turbine 15, which drives process equipment, and thence to first flash vessel 17, overhead gas therefrom (principally methane) being recycled as previously described. Rich bottoms from vessel 17 in line 22 is heat exchanged with feed in exchanger 8, and then passed to a second flash vessel 26 where most of the CO 2  is released. This gas passes through glycol contactor 28, and then used to drive turbine 52 before being vented. The semi-rich bottoms passes to a further flash vessel 37, and optionally in turn also to flash vessel 43, where the bulk of the residual CO 2  is removed. Part of the semi-rich solvent is then passed by line 51, pump 52 and line 55 back to an intermediate point of absorber 10, while the remainder is passed by line 56 to stripper 57, where the other impurities are removed, lean solvent bottoms passing back by line 68 to the upper part of absorber 10. If feed gas is low in CO 2  content but high in H 2 S, the feed gas is passed to the process by line 73, glycol drier 76 and lines 74, 75 to an intermediate point of the column, and not to the base.

Filed: 1936-11-17
Abstract: 481,212. Two-stroke engines. YOUNG, R. D. Nov. 17, 1936, No. 31424. [Class 7 (ii)] In a two-stroke engine in which the combustion chamber A is located within a piston 5 which reciprocates over a fixed piston 7, the latter piston is adjustable to vary the compression ratio. Links 51 connect it to eccentric pins on rotatable members 50 having operating arms 54. The charge is drawn into a pump space B through a non-return, or enginedriven, valve, and one or more ports opposite ports 12 through which it is transferred, after compression, to the port 16 by an external transfer passage. An igniter or a liquid-fuel injection device is exposed by the port 16 at the end of the compression stroke, exhaust subsequently taking place through ports 17, and oval-sectioned exhaust pipes 18. If the engine is an oil engine the compression ratio is arranged to be adjusted so that compression ignition will take place. As the cylinder is protected from explosion pressure it may be constructed from aluminium or copper alloy. After removing the igniter a scraping tool can be inserted through the port 16 to remove the carbon from the combustion chamber.

Abstract: 468,918. Directive wireless signalling. BRONZAVIA SOC. ANON. Nov. 18, 1936, No. 31623. Convention date, Nov. 18, 1935. [Class 40 (v)] The direction of an incoming signal is indicated by a cathode-ray tube in which the beam is moved synchronously with a rotating aerial and which is arranged to indicate only the maximum or minimum of the received energy and the corresponding position of the rotating aerial. In one embodiment, Fig. 1, the signals from a frame aerial 1 rotated by a motor M are combined with those from. a non-directional aerial 2 the output from the receiver AD being applied after rectification to the control electrode 4 of a cathode-ray tube 3. The electrode 4 is polarized so that an indication, which may be either a bright spot or a gap in the path traced by the beam, is produced only when the received signal passes through a maximum or minimum value. If a circular path for the beam is desired the pairs of deflecting plates 8, 9 are supplied with potentials in quadrature from a generator 10, 11 mounted on the shaft of the motor M. Alternatively a straight line trace may be produced by mounting a rotary potentiometer on the shaft to produce the deflecting potential for one of the pairs of plates 8, 9. The indication may be produced alternatively by applying the peaks of the rectified signal to the anode of the tube to produce a radial deflection of the beam. In order to produce a sharper maximum or minimum the rectified signal may be passed through an amplifier biassed back to be responsive only to an input of above a predetermined magnitude. The distance of the transmitter may be estimated by controlling the amplitude of the deflecting potentials produced by the generator 10, 11, Fig. 8, in accordance with the signal amplitude derived from an amplifierdetector 15 coupled to the non-directional aerial 15. Alternatively, the anode potential of the cathode-ray tube may be similarly controlled, the distance of the indicating mark from the centre of the trace being in each case a measure of the distance of the transmitter. Systems are also described, capable of giving directional indications of a plurality of transmitters simultaneously.
