Abstract: 1,037,785. Bellows-type expansion joints. PLESSEY CO. Ltd. June 6, 1963 [June 2, 1962], No. 21936/62. Heading F2G. Two sections 1, 2 of a duct are connected by bellows 4, 5 to a widened duct portion 3. Two or more identical capsules 6 each having rigid end walls 7, 8 and a bellows 11 forming its peripheral wall are arranged coaxially inside the duet portion 3 and have their outwardly facing end wall 7 anchored to a spider structure 9 or 10 fixed in the adjacent duct-end section by a link 14 and their inner facing end wall 8 anchored to the other spider by a link 15. Each capsule 6 is sealed and may be evacuated or filled with air or gas at any desired pressure, e.g. by being vented to the atmosphere. The sizes of the capsules are such that pressure on the capsules produces a force tending to move the ducts 1, 2 together and opposes the force produced by pressure on the ducts 1, 2, 3 tending to separate the ducts 1, 2. A modification (Fig. 2, not shown) shows the principle applied to coaxial ducts wherein the ducts 1, 1a are joined to ducts 2, 2a by bellows 4, 4a and a widened duct 3 and a shell 3a and enclose coaxial capsules 6, 6a. The pair of links 15 joining the faces 8 of each capsule to the duct ends employ cylindrical shells 115 each embracing one of the capsules 6, the walls of the shells having recesses 116 which are mutually offset by right angles about the axis of the duct to avoid mutual interference of the shells. In the second modification a pressure gauge 17 is connected by a line 18 to the space between the capsules 6, 6a to indicate leaks occurring in the outer capsule, since only the inner capsule is normally vented to atmosphere. The modification shown in Fig. 1 may have shroud members extending over the bellows portions 4 and 11 to reduce turbulence produced by the corrugations of the bellows.

Abstract: 1,251,943. Thyristor switching circuits. S. OKUHARA. 3 Feb., 1970 [5 Feb., 1969; 6 March, 1969; 18 March, 1969; 26 July, 1969], No. 5189/70. Heading H3T. [Also in Division G4]  In a direction indicating system the direction is indicated by the sequential illumination of a number of lamps, this cycle repeating so long as a control switch is closed. A lamp once illuminated remains illuminated until the end of the cycle when all the lamps are extinguished together. In one embodiment, Fig. 1, for sequentially illuminating three lamps 21, 22, 23 upon successive pulses supplied by a trigger pulse generator 3, each lamp is connected in series with a respective silica controlled rectifier (SCR) 11, 12, 13 across a D.C. source. Initially, none of the SCR's 11-14 conduct. The cathode electrode of diode 31 is not biased and the first trigger pulse reaches gate electrode of SCR 11 and lamp 21 is illuminated. Due to conduction of SCR 11 the cathode voltage of diode 32 becomes zero and thus the second trigger pulse causes SCR 12 to conduct and lamp 22 is illuminated. Similarly, the third trigger pulse causes conduction of SCR 13 and lamp 23 is illuminated. On the fourth trigger pulse SCR 14 conducts and capacitors 61, 62, 63 discharge through SCR 14 causing the voltage of the anode electrodes of SCR's 11, 12, 13 to become negative for a short period whereby the SCR's 11, 12, 13 become non-conducting and the lamps 21, 22, 23 are simultaneously extinguished. However, SCR 14 remains conducting and capacitor 61 becomes oppositely charged so that the anode electrode of SCR 11 is positive and the anode electrode of SCR 14 is negative. When the trigger pulse comes again to repeat the cycle the SCR 11 conducts to illuminate lamp 21 and the capacitor 61 discharges whereby the anode electrode of SCR 14 becomes negative for a short period and SCR 14 becomes non- conducting. Resistors 82, 83 form charging circuits for the capacitors 62, 63, respectively. In a modification (Fig. 2, not shown) the resistors 82, 83 are replaced by resistors (87, 88) connected to the negative terminal of source 1. In further modifications (Figs. 3, 4, not shown) corresponding to Figs. 1, 2, respectively, the resistors 51, 52 are each associated with a normally-closed series switch (91, 92). To indicate an emergency condition these switches are opened whereupon when switch 2 is closed all the lamps 21, 22, 23 flash on and off simultaneously. In a further embodiment (Fig. 5, not shown) the circuit controls two groups of lamps respectively indicating right and left turns, selection of the desired group being obtained by a two-position switch in series with the D.C. source 1. Further, each SCR 11, 12, 13 is shunted by a tell-tale lamp which goes off when the associated SCR conducts.

Abstract: 1,257,728. Rotary positive-displacement compressors. H. CHAPUIS. July 9, 1969 [July 17, 1968], No.34633/69. Heading F1F. The rotor 1 of an outwardly-sliding-vane type of air compressor is fed with lubricant through a pipe 15 and orifice 19 in a stator 3 while charging an air reservoir 14. To prevent flooding when a non-return valve 13 in a delivery pipe 12 closes a pressure-actuated valve 26 also closes due to a pipe 8 being shut off from the atmosphere and connected to the reservoir by a pilot element 9. The change of pressure in the pipe 8 also closes a valve 5 in a suction pipe 4 and opens a valve 21 to unload the compressor by connecting delivery pipe 11 to an annular expansion-chamber 28, which is vented to the atmosphere through an orifice 29 and air filter 7. The partial vacuum in the pipe 4 is regulated by a valve 30. While the compressor is unloaded a small quantity of lubricant is supplied by an auxiliary reservoir 23 through a choke 25a, this reservoir being charged previously by separation of lubricant from the air flowing to the reservoir 14. Lubricant collected in the chamber 28 escapes through the valve 30. The lubricant in the pipe 15 is cooled and filtered at 16 and 17, and may be further pressurized by a pump (not shown). When said pump is provided the valve 26 is replaced by a two-way valve effects recirculation through the pump when the compressor is unloaded. Alternatively, the various valves are actuated by electric signals from the element 9.

Abstract: 1,264,277. Image detector. STANDARD TELEPHONES & CABLES Ltd. 30 June, 1970, No. 31499/70. Heading H4F. [Also in Division G1] An image reproducer and/or converter, insensitive to changes in the level of overall or ambient illumination, comprises a parallel connected array of photo-conductive detectors 10, coupled to respective light emitting means 19, e.g. diodes, and fed by a constant current source, such that even though such an overall change causes the conductance of the detectors to vary by equal amounts, there is no change in the current flowing in the detectors and so no change in the brightness of the light emitting means. A localized change in illumination, e.g. that of the object of interest, varies the distribution of current flowing within the array and a corresponding change in the brightness of the respective light emitting means. The constant current source comprises a constant voltage source having its voltages set by potentiometer 17 and comparing its voltage with that set up by the detector currents across current monitoring resistor 15. Departure of the voltages from equality causes an adjustment of the base voltage of transistor 14 to regain said equality. Each detector has a trimming resistor 12 and a load resistor 11, the latter supplying an output voltage for application, via an operational amplifier 18 to the photodiode. The output voltage is compared at the amplifier with a reference voltage derived from the constant current source. The detectors may be infra-red sensitive Mercury/Cadmium/Telluride detectors to give a thermal to visible image conversion.
