Patent GB-938595-A (GB)
Title: Improvements in or relating to hydraulic pumps or motors
IPC: F01B3/10
Filed: 1960-01-13
Abstract: 938,595. Swash plate pumps. VICKERS Inc. Jan. 13, 1960 [Jan. 14, 1959], No. 1225/60. Class 102(1). [Also in Group XXIX] A reciprocating pump comprises a rotating cylinder block 18 housing axial pistons whose end face contacts a valve plate member 62 formed with arcuate slots 60, 72 communicating respectively with connections 52, 64. The high pressure connection 52 leads through passages 114, 112, and the high pressure acts on the end of a spring loaded valve 104. When this pressure is sufficient to move the valve 104 to the right against the spring 118 high pressure liquid is fed through passages 108, 88 to act on the end of a spring loaded rack member 74, the movement of which causes rotation of the valve member 62 to vary the phase relationship between the arcuate slots 60, 72 and the reciprocating movement of the pistons. The valve member 62 is housed in an elliptically shaped housing 42 and when the valve is in its normal unadjusted position the closed gaps between the arcuate slots 60, 72 occur at top and bottom dead centre position. Passages 144, 145 are provided in these gaps leading to the surface of the valve to provide a bleed into the chamber 40 formed between the valve 62 and housing 42 - when the valve plate is adjusted. Specifications 778,186 and 938,596 are referred to.

Title: Improvements in or relating to composite hydromechanical constant-speed drives
Inventor: MOSS NORMAN
IPC: F16H3/56
Filed: 1963-01-11
Abstract: 1,062,631. Variable speed-control. PLESSEYU.K. Ltd. Jan. 1, 1964 [Jan. 11, 1963], No. 1344/63. Heading F2D. [Also in Division F1] A torque-splitting planet gear between an input shaft 1, driven by an aircraft turbo-jet engine, and an output shaft 2 driving at constant speed an A.C. generator, and also adapted for starting the engine from an auxiliary hydraulic power source and for driving auxiliaries when the engine is stationary comprises input and output suns 4, 5 and a stepped planet carrier 8 driven by a fixed displacement motor 11 energized by an input-driven pump 12, the displacement of which is variable by a swashplate controlled through an hydraulic ram 17 by an output driven governor 20 so that the displacement of the pump 12 is proportional in direction and magnitude to the difference between actual and desired output speed. Hydrostatic, circuit.-For engine starting and independently running auxiliaries a source of hydraulic pressure 22 is connected to the high pressure side of the pump/motor circuit through a non-return valve 23. The hydraulic source control 25 is interconnected with a valve 26 to cut off and lock the motor 11 and a valve 27 to change over connections between the governor 20 and ram 17 so that the pump 12 runs as a motor to start the engine. The governor would then still control the output shaft speed. The engine is started by the motor 11 which is connected through a sprag clutch to the input 1 when the planet carrier speed tends to be greater than the input 1. The pump 12 may then also be driven as a motor. The motor 11 may be connected to the output for ground running through a sprag clutch engaged when its speed is above normal. Both the pump and motor may be used with the sprag clutch drives for driving auxiliaries with the engine disconnected. The pump 12 may be driven as a motor for starting with liquid fed from the low pressure part of the circuit with the swash- , plate at the same inclination as for pumping.  The invention may be used in conjunction with that claimed in Specification 952,982.

Title: Method and apparatus for filling containers
IPC: B65B1/16
Filed: 1967-01-10
Abstract: 1,130,802. Filling containers with powdered material. CARTER ENG. CO. 10 Jan., 1967 [1 April, 1966], No. 1348/67. Heading B8C. [Also in Division F2] After partially filling a container with fine particulate material through a reduction in container internal pressure, the pressure is then reduced again, prior to further filling, at a slow rate in order to avoid particles being sucked into the screens of the gas-withdrawal ports. In the embodiment, a container 4, is evacuated through suction passages 24, in a filling head 2, whilst an inflatable valve 16 is inflated to block off the passage 14 leading from a supply hopper 8 to the container. The valve 16 is then opened and closed one or more times to introduce shots of the material into the container until it is partially filled. The rate of vacuum withdrawal is then reduced in order to avoid the particles being sucked on to vacuum screens 22, and when the vacuum has been increased and remains constant through air leakage, further shots of material are introduced into the container until it is filled. A valve (40), Fig. 4 (not shown) effects the varying rates of vacuum withdrawal. The rate of operation of the valve 40 may be adjusted by a manual throttle valve (78).

Title: Improvements in electric couplings
IPC: H01R13/703
Filed: 1929-01-15
Abstract: 327,993. Wynne, A. C. Jan. 15, 1929. Plug couplings combined with electric switches. Comprises a plug and socket type coupling in which the contacts carried by the detachable member are provided with insulating sleeves to prevent accidental contact with " live " parts when it is not in full engagement with is counterpart. In the form shown in Fig. 3, where a third pin P1 on the removable plug member is interlocked with a switch, the contact pins P2 have insulated sleeves S2 which extend down from the base B to a shoulder S1. When the plug is being withdrawn, the switch is operated to break the circuit just before the lower ends S1 of the sleeves leave the apertures in the socket member; similarly when the plug is pushed in, the ends S1 of sleeves just enter the socket apertures before the circuit is completed. In a modification shown in Fig. 6, the sockets t3, t4 are sunk below the surface of the socket element so that the pins enter up to the beginning of the insulating sleeve before the points enter the sockets. Specifications 13455/12, 307,584, and 308,951 are referred to.

Patent GB-347107-A (GB)
IPC: C10C1/04
Filed: 1930-01-16
Abstract: <PICT:0347107/III/1> Tar is distilled in a non-extraneously heated still by direct contact with highly heated gases e.g. those from coke ovens, the tar being previously preheated and partially distilled by indirect heat exchange with the gases after they leave the tar still. The gases from a battery of coke ovens 5 are collected in a heavily insulated header 11 and passed into a still 13 supplied with tar which is sprayed into the path of the gases by a rotating roll 14. The gases and vapours pass from the still through a separating chamber 17 to a heat exchanger 19 through which the tar from a pipe 20 is passed in a coiled pipe 21.  The tar thus heated is flashed in a chamber 24 and the resulting vapours are condensed in a condenser 26 while the residual tar is passed through an insulated pipe to a spray head 29 in the chamber 17 from which it is delivered through an insulated pipe 32 to the still 13.  Light oils condensed from the gas stream in the exchanger 19 are collected in a receiver 22 while the gases are finally passed to a scrubber 40.  A pitch having a melting point above 400 DEG  F. is formed in the still 13 and drawn off through a trap 33 by an adjustable arm 34 to a trough 35 where it is sprayed with water. Specification 346,753 is referred to.

Title: Process and apparatus for the concentration of syrups and like liquids
IPC: B01D1/06
Filed: 1936-01-21
Abstract: <PICT:0458963/III/1> A process for the concentration of liquids consists in pouring the liquid in a thin layer on to a surface maintained at a sufficiently high temperature to produce the phenomenon of calefaction.  This phenomenon is defined as corresponding to the spheroidal state, the generation of vapour from the surface in proximity to the heating surface being such as to maintain the liquid out of contact with the surface.  In the case of grape juice, which boils at approximately 100 DEG  C., the temperature of the heating surface must be at least 145 DEG  C. to produce the desired phenomenon.  The juice flows from a reservoir 18 through a heat-exchanger 14 to rotary spray nozzles 13 which discharge it on to a funnel-shaped surface 5 heated to the required temperature by a jacket 1.  The concentrated liquid flows through the heat-exchanger 14 to heat the incoming juice and is drawn off through tap 26.
