Abstract: 811,309. Controlling gas burners. GAS COUNCIL, and PERL CONTROLS Ltd. Oct. 26. 1956 [July 29, 1955], No. 22000/55. Class 75(1) [Also in Groups XXIX] A combined gas governor and flame failure or ignition filament failure device, comprises a diaphragm-actuated gas governor valve 13, a plunger 6 engageable with the valve and an armature 8 mounted on a sealing diaphragm 9 and urged by a spring 10 away from an electro-magnet 2 when the latter is de-energized. To open the valve, a pilot jet supplied with gas through a by-pass from the valve inlet 19 is lit whence a thermocouple is heated and energizes the magnet 2. A spring- loaded button 17 is then pressed upwardly to move the magnet into engagement with the armature which on release of the button moves downwardly together with the magnet to allow the plunger 6 to fall and the valve 13 to open an -amountdetermined by a weight 22 and outlet pressure acting on the diaphragm 21. In another embodiment, the magnet is connected in series with, e.g. a battery and a hot wire filament, so that when the filament is energized the gas issuing from the pilot jet is lit and closes a circuit to energize the magnet. In the event of pilot flame 'failure or ignition filament failure the current supplied to the magnet 2 is cut-off whence the magnet is de-energized and the spring 10 urges the armature upwardly and the plunger 6 to close the valve 13. Specification 727,374 [Group XXIX] is referred to.

IPC: F02M1/00
Filed: 1920-07-22
Abstract: 163,936. Feroldi, E. July 22, 1920. Spray carburettors.-The admission of fuel to the constant level chamber 4 is controlled by a spherical float 8 independent of the needle valve 7 which has a disc 9<1> rigidly secured thereto and against which the float acts. The float chamber is extended horizontally so that in the event of the vehicle and carburettor being inclined, the float travels from the position shown in broken to that in full line, the constant level being then raised from A to B and the depth of fuel below the nozzle 1<1> being maintained substantially constant. Raising of the fuel level does not occur for tilting in the opposite direction. In another construction which does not allow for tilting, the float is allowed very little lateral movement, and acts upon a concave disc secured to the needle valve.

Title: Method And Apparatus For Transmitting Digital Information
IPC: H04L25/49
Filed: 1966-05-18
Abstract: 1,152,452. Electric selective signalling. SOC. ALSACIENNE DE CONSTRUCTIONS ATOMIQUES DE TELECOMMUNICATIONS ET D'ELECTRONIQUE " ALCATEL." 18 May, 1966 [21 May, 1965], No. 22114/66. Heading G4H. [Also in Division H4] Data is represented by a cycle of alternating voltage in which the time of occurrence of the intra-cycle polarity change is indicative of the data. In a transmitter, Fig. 4a, two parallel bits pass to a diode matrix 10 feeding a corresponding one of four gates 508. The gates are enabled in succession by clock pulses from diode matrix 4 fed by counter 3. A bi-stable circuit 12 set to the 1 state by the first clock pulse in a cycle is reset to 0 by a pulse from one of the gates, so that the bi-stable circuit's output is a signal of the form defined above. At the receiver, Fig. 4b, the positive- and negativegoing zero-crossings in the received signal are obtained by differentiation at 20, 21 respectively. The first of these is used for the synchronization of a local clock circuit as described below, and the second passes to a gating arrangement 45, 35 which, in conjunction with the local clock pulses, determines whether the zero-crossing lies within first and/or second overlapping periods or in neither, and hence which of the four possible bit pairs was at the transmitter input. The positive going transition passes via gates 26 or 31 dependent on whether the transition occurs in the first or second half of the receiver cycle, and causes a pulse to be added to or deleted from the pulse train from generator 22 which is fed to counter 27, thereby synchronizing the counter.

A protective coating is applied to electrical components (e.g. capacitors) having leads extending therefrom, wherein plural components are spacedly positioned between two longitudinal metallic strips with the leads extending laterally therefrom, and a molten insulating substance which is solid at the working temperature is poured into the space between the strips to contact the exterior portions of the components and bond to the metallic strips ; the components being separable by sawing after solidification of the insulation. Aluminium foils 8, 8<1> exteriorly coated at 5, 5<1>, 5<11> with a synthetic polycarbonate insulating material (e.g. 4-4<1>-dimono-oxyarylalkane) are placed within the side frames 10, 10<1> of a clamp (Figs. 2, 3) and over a central separating sheet 9, and two sets of capacitors 6, 61, 611 and 7, 71, 7<11> are spacedly disposed between the exposed surfaces of the foils; the leads protruding laterally between U-shaped silicone rubber strips 11, 11<1> and 11<11>, 11<111> closing the bottom and sides of the frame and the insulating layer overlapping the longitudinal sides of the foils between the side-frames and the strips, so that a molten casting resin may be poured into the remaining space to bond to the foils, the insulating layer and the capacitor units and form when cold a solid strip containing plural sealed in units which may be separated by sawing (Fig. 1, not shown). The foils may be coated on both sides with a continuous insulating layer (Fig. 4, not shown) or carry rectangular sections of insulating material on their inner faces opposite each capacitor unit (Fig. 5, not shown). The units may be spacedly welded or cemented between two strips of insulating material prior to insertion between the foils in the casting clamp (Figs. 6, 8, not shown) or an additional metal foil may be folded round each capacitor unit before casting with or without the interposition of a further insulating layer (Figs. 7, 9, 10, not shown). Canned capacitor units may be inserted between the metal foils either separately or as a connected chain and embedded in casting resin as above (Figs. 11, 12, not shown). The coated surface of the foils may be initially roughened, or the foils may be produced by depositing metal on an insulating sheet.

Title: Improvements in or relating to friction clutches
IPC: F16D13/71
Filed: 1939-08-01
Abstract: 533,506. Friction clutches; springs. BORG & BECK CO., Ltd. Aug. 1, 1939, No. 22337. Convention date, Jan, 21. [Class 80 (ii)] [Also in Group XXXII] A friction clutch comprises pressure and cover plates 16, 17 and a packing spring 42 between them in the form of an annulus. This spring may be arcuate in radial cross section, and its inner and outer edges may both lie on the same side of the plane through its middle and engage the respective plates. The spring may have radial slits 50, Fig. 13, opening into its inner periphery and extending outwardly less than half the width of the annulus to decrease the load required in the final stage of deflection. This may also be achieved by forming openings 51a, Fig. 14, in the neutral zone. The cover plate 17, Fig. 7, is centrally depressed towards the fly-wheel 14 and may have holes 27 through which the outer ends of the release levers 25 pass to engage lugs 28 of the plate 16. The levers pivot on the edge of the hole 27 and are retained by lugs 53 engaging lateral extremities of each hole 27 and by a pivoted resilient bar 33. In a modification the release levers are wholly outside the plate 17 and are each connected to the plate 16 by a bolt. In another modification the central part of the spring engages the plate 16 and its periphery the plate 17. In packing, for transit, the levers and pressure plate 16 are retained in the cover plate 17 by bars 69, Fig. 3, inserted through openings in the plate 17 to engage lugs 72 of the plate 16. With this construction the clutch can be made thin and, as each lever is disposed substantially entirely on one side of the radial plane of its fulcrum, centrifugal force tends to increase the pressure on the clutch faces. Specification 533,563 is referred to.

Filed: 1938-07-28
Abstract: 513,815. Moulding patterned articles from synthetic resins &c. GARTHE, D. July.28, 1938, No. 22496. Convention date, July 28, 1937. [Class 87 (ii)] Coloured patterned articles such as lettered signs are formed from artificial resins &c. by moulding a main body having cavities extending for the most part through the whole body and then forcing material of a different colour into the cavities and hardening it, the pattern material extending over at least part of the rear face of the main body so that the two bodies are inseparably interlocked. As shown, the body part is moulded in a press member comprising upper and lower dies d, c, and a frame f supported on the lower die. The lower die carries projections g which produce the pattern cavities and for the most part extend the full height of the mould. At places the projections g are of less height so as to form small bridge pieces i connecting the various parts of the body. When the body part a has been moulded it is removed in the frame f and placed on a second flat die. Patterning material b is then forced into the cavities in the body by a top die, excess material being provided so as to form a thin layer of pattern material covering the back of the body part and connecting the various parts of the pattern. Any burr which is formed may be subsequently ground off. The projections g may be provided on the upper die and the dies may be formed of a number of parts such as type. Specifications 414,789 and 467,419 are referred to.
