Patent GB-856831-A (GB)
Title: Improvements in or relating to power supply systems
Inventor: CAMPBELL HENRY H
IPC: F02C7/00
Filed: 1957-10-21
Abstract: 856,831. Governors; turbines; motor-power plant. BORG-WARNER CORPORATION. Oct. 21, 1957, No. 32843/57. Classes 57 and 110 (3). A centrifugal governor 14 for controlling the flow of fluid to a turbine 12 comprises biasing mechanism which is so controlled by the flyweights 57 of the governor as to move a fluidcontrol valve 34 in flow-restricting and flowincreasing directions in response to increases and decreases respectively of the motor speed and includes a thrust-release means 65, 67 for disconnecting rotatable and non-rotatable parts of the biasing mechanism when the contro valve is in a position of maximum flow restriction. As shown applied to an auxiliary drive for a gas-turbine fuel pump which is normally driven by an electric motor 11, the fly-balls 57 are received in radial grooves 58 in the upper face of the turbine wheel 21 which is mounted on the shaft 15 for co-operation with the stator 24. The radial movement of the balls 57 controls the vertical movement of an actuator 55 which is movable axially along the shaft 15 and has lugs 62 engaging with the grooves 58; the operative surfaces of the flyballs and actuator may be hardened. The valve 34, which controls the air inlet 28, is mounted above the actuator and provided with a head 50 for engagement with a seat 51 formed in a valve cage 40 clamped in the main housing 16. The valve is urged towards the closed position by the inherent resilience of a bellows 37 which is anchored at one end to a flange 54 on the valve, and at the other end, to the valve cage 40. The valve is urged towards the open position by a spring 36 mounted between a flanged-sleeve 69 and thrust washer 65 supported in a step 66 formed on the actuator 55. In normal operation, the fuel pump is driven by the electric motor 11 and the fly-balls are forced outwardly by centrifugal force to compress the spring 36 and raise the thrust washer 65 from engagement with a thrust-bearing 67 carried by a flange 68 on the valve head 50 thereby disconnecting the rotating shaft 15 from the stationary valve 34 which is moved to closed position by the action of the bellows 37. If the electric motor fails the balls 57 move towards their inner position and thus permit the valve, under the action of the spring 36, to open. Pressurized fluid, such as air bled from the gas-turbine compressor, is then enabled to flow from the inlet 28 through ports 29 into an inlet chamber 30 and then through the vanes 26 of the stator 24 to maintain the rotation of the turbine wheel and shaft at a reduced speed. The bellows is balanced against changes in fluid pressure by arranging for the fluid to communicate with the interior of the bellows through a number of grooves 72 formed in the valve cage 40, and with the exterior through a clearance space 74 in the bearing 67 and interior of the valve body 38.

Title: New and improved tobacco treatment process
IPC: A24B3/02
Filed: 1938-11-12
Abstract: 521,224. Tobacco. THERMAL ENGINEERING CORPORATION. Nov. 12, 1938, No. 32992. Convention date; Dec. 21, 1937. [Class 130] For altering its moisture content and exterminating undesired organisms, tobacco is subjected to a high vacuum, preferably high enough to remove substantially all the 'air from the tobacco, and then treated with a mixture of steam and water. whereby the moisture content is increased. The water in the mixture may be in finely divided form and the mixture increases the absolute pressure on the tobacco to a higher but still sub-atmospheric value. The amount of water used may be in excess of an amount needed to prevent superheating of the steam at' the sub-atmospheric pressures prevailing. The tobacco is " soaked " by maintaining it in contact with the steam and water at substantially constant pressure for an interval, for example, by continuing to supply steam at a reduced rate, and is then cooled by submitting it to an.increased vacuum sufficient to cause the evaporation of moisture. The steaming, " soaking " and cooling steps may be repeated one or more times, and the treatment chamber is finally vented to the atmosphere. The treatment is carried out in one or more chambers 4, 4<SP>1</SP> each provided with removable closures 5 and connected through valves 6 and a T-fitting 7 to a first-stage steam-jet ejector 8 discharging through a pipe 9 into an intercondenser 10. The fluid outlet from the intercondenser 10 is connected to a second stage ejector 14 and intercondenser 15 and to two third-stage ejectors, 18, 18<SP>1</SP> connected in parallel and discharging to the atmosphere or to a final condenser. The intercondensers are supplied with water through a valved pipe 11 and water and condensate withdrawn by pumps 13,17. Steam is admitted to the treatment chambers 4, 4<SP>1</SP> at spaced points from manifold pipes 27 and branches 28, the pipes 27 being connected to a steam supply pipe 21 through remotely controlled valves 29 and manual valves 30. Restricted bye-pass pipes 31 with remotely controlled valves 32 allow the admission of steam at a restricted rate. Water is also admitted through branches 34 from water manifold pipes 33 provided with remotely controlled valves 46 and manual valves 50. The branch pipes 28, 34 are connected to the chamber 4 as shown in Fig. 2, the pipe 28 being connected by a T-fitting 40 and a nipple 39 to a collar 38 sealed through the wall of the chamber 4, and the pipe 34 passing axially through the fittings 38 ... 40 to a nozzle fitting 42 threaded in a bushing 37. The water jet impinges on the central plane portion of a disc D having a tapered rim, and steam flows through openings 45 towards the disc to aid in spraying the water. The chambers 4, 4<SP>1</SP> may be vented to the atmosphere through pipes 35 controlled by valves 36. The remotely controlled valves 6, 29, 32, 46 may be operated by diaphragm or electric means of known construction. Specification 473,842 is referred to.

Title: Transreceivers
IPC: H04W88/02
Filed: 1968-07-19
Abstract: 1,185,789. Multiplex radio signalling; communication systems. C.I.T.-COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 19 July, 1968 [11 Aug., 1967], No. 34556/68. Headings H4K and H4L. In a radio-communication system in which transmitter-receiver stations set up duplex links by hunting for a pair of idle carriers in a plurality of available pairs of carriers, each station includes an adjustable coder for producing the code identifying a desired station, a decoder for recognizing its own identifying code, a generator for generating the pairs of carriers, means for testing for idle carriers and means for stopping the testing when a pair of idle carriers is found. Speech signals may be transmitted as FM and the code signals as AM. As shown in Fig. 1a each station has a radio transmitter 101 and radio receiver 102 connected to the aerial via a duplexer 103 and includes a microphone 105 and earpiece 106 forming a telephone handset. The transmitter can be modulated by a variable coder 62 for calling a required station and also with a fixed frequency # 0  from an oscillator 111 providing an engaged signal, the frequency # 0  being above the audio range. In the standby condition with the handset hung up (switches 99, 99<SP>1</SP> open) a stepping device 112 is energized and a rotary commutator 113 is operated whereby a generator 115 provides stable frequencies grouped in pairs f 1 , f 2 , the frequencies of each pair being supplied alternately via a switch 116 synchronized with device 112 to the receiver 102, which is arranged to be tuned successively to these two frequencies. The receiver 102 feeds a decoder 91 which recognizes its own calling signal, a detector 92 for the engaged tone # 0  and a detector 93 for the speech signals. If the operator of station X wishes to call another station Y he lifts the handset and dials the required number by means of the coder 62, the code being stored by means not shown. At the first position of the stepping device for which both frequencies of a pair are free, i.e. no frequency # 0  is received, a logic circuit 95 stops the stepping device 112 and the frequency f 2  of the pair is supplied to the transmitter 101. The logic circuit 95 closes contact b 1  via line b to apply the code of station Y to modulate the transmitter. At station Y the commutator 113 is stopped by logic circuit 94 when the code of station Y is recognized by decoder 91 and the engaged tone f 0  is supplied to the transmitter 101. At station X the tone f 0  is detected at 92 and logic circuits 95, 96 cause the engaged tone f 0  to be transmitted instead of station Y code and when tone f 0  is received at Y the duplex link is established. On replacement of the handsets, both stations are returned to the standby condition. If a handset is not replaced as required, a logic circuit 97 recognizes the absence of tone f 0  and operates a control circuit 98 which puts the station in the standby condition.
