Abstract: 1302930 Brake control valve apparatus WESTINGHOUSE BRAKE & SIGNAL CO Ltd 20 Sept 1971 [16 Oct 1970] 49178/70 Heading F2F A fluid operable brake control apparatus has brake cylinder inlet and exhaust valves 13, 14 for controlling the supply of fluid pressure into and out of a brake cylinder through pipes 10 and 11, respectively. There valves are operated by a pressure-responsive diaphragm 16, 18 separating chambers a and b connected to the brake pipe at 8 and an auxiliary reservoir of pressure from which pressure is applied to the brake cylinder. The diaphragm 16 is biased downwardly to prevent its movement by a spring 30 acting through a push-rod 28, this bias being relieved by pressure via passage 31 from a quick service bulb chamber 20 acting upwardly on diaphragm 32 to compress the spring 30 immediately following brake application to give stable and pronounced action of the brakes. Initially, the pressures in chambers a and b are balanced, but when the pressure is reduced in the brake pipe 8 in order to apply the brakes, the diaphragm 16 lifts and so opens valve 23 to allow brake pipe pressure to enter the bulb capacity 20, which comprises spring 30 to allow rapid lifting of the diaphragm 16, thus closing the reservoir charging valve 15 and brake cylinder exhaust valve 14 and opening brake cylinder inlet valve 13 to connect auxiliary reservoir pressure to the brake cylinder. When the auxiliary reservoir pressure falls to brake pipe pressure the diaphragm 16 descends to close lap valves 21 and 23. The increasing pressure in chamber 20 enables spring 25 to lift piston 33 and valve seat 24 to its upper position so that valve 23 laps off with the inlet and exhaust valves closed, which gives stable action. To release the brakes, the pressure in brake pipe 8 is increased so that diaphragm 16 and stem 19 descend. The spring 25 is overcome and valve 21 is lifted to exhaust the bulb to atmosphere via passage 7, and the system returns to its inactive condition.

Abstract: 1329203 Centrifugal separator GLACIER METAL CO Ltd 1 Feb 1972 [3 Feb 1971] 3778/71 Heading B2P A fluid flow driven centrifugal separator comprises a hollow rotor 2, Fig. 1, including a distribution region 10 for receiving an incoming mixture of denser and less dense fluids, e.g. water and oil, to be separated, the region 10 having outlets 12, 14 respectively to a separating chamber 11 and a driving chamber 13, the separating chamber having respective outlet passages for separated denser and less dense fluids. The fluid mixture is supplied to the region 10 via passages 3, 4, 6, 7, in the separator stator 1 and passages 8, 9 in the rotor 2. The outlets 12, 14 from the region 10 are in the form of circumferentially distributed sets of nozzles which may be adjustable, e.g. by the provision of automatic control means sensitive to viscosity, to control the distribution of mixed fluid flow to the chambers 11 and 13. The chamber 13 has two driving nozzles 19, 20 through which the denser fluid is discharged providing a tangential reaction force for driving the rotor. The less dense fluid is discharged from the separating chamber 11 via passages 24, 23, 25, 26 and the denser fluid via tubes 28 which open into the driving chamber 13. The tubes 28 may be replaced by an annular duct. In place of the nozzles 12 a split-collar type valve, Fig. 2, may be used to control the flow of fluid to the separating chamber 11. The valve has an adjustable member 31 which can be pre-set by nuts 44 to vary the size of the mixed fluid passage 32. Alternatively, an automatically adjustable valve member 34, Fig. 3, biassed by a spring 35 is used to control the size of the passage 32, the downward drag on the valve being more pronounced the higher the viscosity of the fluid flowing down the passage 23.

Abstract: 1339938 Cutting and welding by fusion YAMATO SANGYO CO Ltd 29 Oct 1971 50388/71 Headings B3V and B3R [Also in Division F4] In a welding and cutting apparatus wherein oxygen from a supply 1 and metallic powder 62 from a tank 60 are fed to a central passage (76) (Fig. 2, not shown) of a torch 70, the supply of powder 62 is cut off by a valve 52 if the pressure increases in a reduction valve 20 through which the oxygen is fed. The oxygen is fed from a cylinder 1 to the torch passage (76) via the reduction valve 20, a conduit 13, a powder flow control valve 40 and conduit 13<SP>1</SP> and to an annular passage (74) of the torch 70 via a conduit 4. The oxygen is also fed via a conduit 10 into the tank 60 containing metal powder 62 to cause the powder to be sucked up into a conduit 61 communicating with the conduit 13<SP>1</SP>; and into a chamber 57 of the valve 52 via a conduit 15 to urge a valve plug 53 into a position where a bore in the plug 53 communicates with the conduit 61. If the powder 62 should ignite within the torch 70 causing the pressure in the conduits 13, 13<SP>1</SP> to increase, the pressure is transmitted through a chamber 22 of the valve 20 and a conduit 14 to the valve 52 causing the valve plug 53 to move to cut off the flow of powder 62. A plug 23 in the valve 20 is raised by the increased pressure in the chamber 22 to close the opening of an adjustable valve passage between the chamber 22 and a further chamber 21 connected to the oxygen cylinder 1 via a conduit 19. The oxygen from the cylinder 1 can pass through the valve 20 via a conduit 12 and restriction 34 which reduces the pressure of the oxygen. The torch 70 may be used without powder 62 by lowering the valve plug 23 by means of a screw 28 to cause the chamber 51 of the valve 52 to be pressurized and the valve plug 53 to be moved to the left. The annular passage (74) of the torch 70 is connected to an acetylene supply 6 via a conduit 8.

Abstract: 1353649 Analogue to digital and digital to analogue converters TECHNICAL MANAGEMENT SERVICES Inc 19 April 1971 [27 Jan 1970] 47154/73 Divided out of 1353648 Heading G4H In an analogue to digital or digital to analogue converter, reference voltages are derived from the secondary windings of a D.C. to D.C. or A.C. to D.C. transformer; the number of turns in the windings varying in accordance with a digital code. In the embodiments described the number of turns in the secondary windings are in the ratio 2<SP>n</SP> : 2<SP>n-1</SP> ... 4 : 2 : 1 and are centre topped. In the analogue to digital converter (Fig. 1) the transformer output voltages are added in steps to the analogue voltage to reduce it to zero. The analogue voltage is applied at 12. MOSFET switches 76 controlled by secondary winding gate driver circuit 20 are closed and the analogue voltage is compared with zero in comparator 14. The output is fed to the first stage of ternary register 16 (it has 3 positions 1, 0 or clear) and closes one of two switches 74 or 78 and opens 76 to connect the highest voltage secondary to oppose the analogue voltage. The resulting voltage is again compared and the next stage switched in according to the comparator output. The process is repeated for all the secondaries, each of which is switched in either in the same sense as or in opposition to the analogue voltage. The resulting set of values in the register are converted to binary in decoder 18 which also comprises means for producing the complement of all the output figures when the voltage is negative. The stepping of the register and the switching of the transformer primary is controlled by clock fed logic 22; the voltage comparisons being made when the secondary voltages are steady. The converter can operate at two different speeds with either one or all the comparisons per input cycle. The digital to analogue converter (Fig. 7) comprises two transformers 10 and the primary switching of each is arranged so that by sampling the secondaries alternately a continuous analogue output is available. The digital data is fed serially from input 226 into register 222 and comprises a lead " 1 ", a fill in bit which allows production of an output equal to twice the most significant bit and the digital number in order of increasing significance. When the lead " 1 " reaches flip-flop 244, the store contents are transferred to latching circuit 244. The output of the latching circuits switches in the required secondary windings and switches 198 select the correct winding alternately to provide a continuous analogue output at 268. A reference direct input voltage is applied at 220.
