Title: A fluid pressure controlled strut or link of variable length
IPC: F15B11/12
Filed: 1950-05-11
Abstract: 679,060. Hydraulic machines. DOWTY EQUIPMENT, Ltd., CUSSONS, R. C., and KNIGHTS, R. N. May 15, 1951 [May 11, 1950], No. 11803/50. Class 69 (ii). A variable length strut comprises an outer cylinder 11 with a piston 12 slidable therein, an inner cylinder 13 movable as one with the piston 12 and having a piston 14, the rod of which extends out through the inner and outer cylinders, and ports 20, 19 through which pressure fluid enters to move the pistons in opposite directions to bring the strut into a length which is intermediate its maximum and minimum lengths. The piston 14 operates as a plunger with a head 18 for limiting outward movement, and the end face of the cylinder 11 has a vent hole 21. Pressure fluid entering at 20 moves the piston 12 to the right, and enters through port 19 to move piston 14 to the left to the positions shown in Fig. 1. When the connection 20 is placed in communication with a return line the pistons are free to move in either direction so that the strut is free to extend to its maximum length or to retract to its minimum.

Abstract: 144,259. Moss, S. A. May 31, 1919, [Convention date]. Regulating.-A centrifugal compressor driven by a turbine actuated by exhaust gases supplies air to the carburettors for the engine. The compressor is fitted immediately behind the propeller of an aeroplane and comprises a double inlet casing 26 with discharge vanes 25, surrounding an impeller 21 supported on a shaft 22, which also carries the turbine rotor 28 and is mounted on bearings 23, 24. One inlet eye is formed by the flared flange 32 which supports the bearing 24, which is cooled by the entering air. The other inlet is the annular casing 33 with its transverse extension 34 which opens forwardly beyond the periphery of the discharge casing 20. Exhaust is caused to pass from the manifolds to the chamber 18 by closing valves on these manifolds. The chamber 18 is provided with a number of nozzles 30, which direct the gases on to the turbine buckets 29. The flange 38 and radial extensions thereof deflect the gases to the atmosphere, and heyond the said radial extensions the buckets are exposed to cooling-air from the conduit 40. From the outward casing of the compressor, the air passes by way of conduit 16 to the carburettors.

Title: Ghost signal cancellation system
IPC: H04N5/21
Filed: 1973-03-12
Abstract: 1429802 Radio receiving systems MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 12 March 1973 [16 March 1972 23 March 1972 18 April 1972 (4) 6 May 1972 3 June 1972 (2) 7 June 1972] 11844/73 Heading H4L Means are provided for removing ghost signals from received television signals by delaying the received signals by an amount corresponding to the delay of the ghost signal, adjusting the level cf the delayed signal to be equal to the level of the ghost signal and subtracting said adjusted signal from the received signal. As shown in Fig. 1, an oscillator 1 is adjusted in frequency by a potentiometer Rt and its output converted to a square-wave at 2. Trigger 2 controls a flip-flop 3 which produces outputs of opposite phase controlling a bucket-brigade device to produce the required delay to the received signals applied thereto. The output of delay 4 is inverted and filtered at 5 and supplied to an operational amplifier 6 where it is combined with the received signal. This arrangement leaves a relatively weak ghost signal at twice the delay of the original ghost in the output of amplifier 6 and in a modification, Fig. 6 (not shown), the video signal is supplied to a sequence of bucket-brigade devices whose respective outputs are alternately inverted and combined via appropriate weighting resistors with the received signal in the amplifier 6. The resulting signal is stated to be free of ghosts. In a further arrangement, Fig. 7, the manual adjustment Rt is replaced by an automatic cancelling arrangement. The sync. pulses are separated from the video signal at 12 and differentiated at 13, Fig. 8A showing the separated sync. pulse together with its ghost pulse and Fig. 8B showing the differentiated pulse with the delay td of the ghost signal. The interval td is converted to a corresponding voltage at 14 to control the frequency of oscillator 15 and thus via the clock generator 16, the delay devices 17, 18, whose outputs are combined, as in the previous arrangement, with the video signal at 21. The amount of attenuation at 19, 20 may be adjusted manually or may be derived automatically from the circuit 12. More delay elements may be connected as required.

Abstract: 1381867 Flarestacks BRITISH PETROLEUM CO Ltd 5 April 1972 [29 April 1971] 12068/71 Heading F4T A method for disposing of low pressure fuel gas comprises passing steam at pressure over a director body having a curved surface 10 so that it entrains surrounding air, the steam and air then being passed into the fuel gas which emerges from an internal passageway 17 of the director body, the resultant mixture of steam, air, and fuel gas then being burnt. During use steam flows into the steam line 14 and from there passes through inlet 11 and flows outside and round the curved part 15 of the director surface 10. A low pressure zone is induced in this portion of the surface due to the change of direction of the flow of the steam and thus air is induced to flow with the steam over the part 16 to the inlet 12 of the fuel gas supply. The fuel is conveyed to the inlet 12 via the fuel line 17 which continues through the director body. The fuel and the steam and air burn in the region above the inlet 12.

Filed: 1964-03-23
Abstract: 1,043,781. Valves. DANFOSS A.S. March 23, 1964 [April 2, 1963], No. 12135/64. Heading F2V. A thermally-actuated valve member 5 is biased to a closed position by a spring 12, the latter seating against a flange 16 of a non- rotatable threaded sleeve 18. The latter cooperates with a rotatable threaded sleeve 20 having a flange 21 provided with projections 29 that engage recesses 28 in a toothed disc 22 driven by a pinion 24. To increase the load on the valve member, the pinion is rotated to rotate disc 22 and sleeve 20, the drive being transmitted by the recesses 28 and projections 29. To decrease the said load, the pinion is rotated in the opposite direction, but since the recesses and projections have rounded edges 32, 33 they cannot constitute a direct coupling in this latter direction of rotation. Instead, the flange 21 and disc act as a friction coupling. When the disc abuts stop 7, continued rotation causes the projections to ride out of the recesses to prevent over-tightening against the stop. In a modification, not shown, the sleeve 18 is rotatable, the sleeve 20 is non-rotatable and a drive disc is positioned on the flange 16 between the latter and the spring. The valve member 5 is opened by a temperature-sensitive device 11 connected by capillary tubing 10 to the chamber above a diaphragm 14.

The shaft 11 may be replaced by one or more rectangular sectioned shafts, each of which may be independent of the caravan walls 1, 2. In an alternative embodiment, the shaft may be connected directly to the upwardly extending duct portion 15. The shaft may be formed as a flattened nozzle. The air supply duet (16) has branch ducts (17) serving floor outlets (18).
