IPC: F16H13/02
Filed: 1917-12-03
Abstract: 119,575. Chadburn, W., and Chadburn, W. R. Dec. 3. 1917. Clutches, friction.-In centrifugallyoperated friction clutches, heavy blocks 8, turning on pivots 9 on a heavy plate 5 on the vertical driving- shaft 1, are connected by an adjustable spring 10 and carry ring-halves 17 in recesses in which are arranged plates 16 secured to the blocks 8 and provided with friction pads 15 normally pressed into engagement with a drum 7 on the driven shaft 2.
Patent GB-634675-A (GB)
Title: Improvements in or relating to apparatus using a magnetisable recording medium
IPC: G11B5/004
Filed: 1947-07-07
Abstract: 634,675. Electromagnetic sound recording. GENERAL ELECTRIC CO., Ltd., and POLGREEN, G. R. July 7, 1947, No. 17863. [Class 40 (ii)] In electrical recording or reproduction apparatus of the type employing a magnetisable recording tape, the tape 1 is fitted to the apparatus in the form of a flexible endless band and is driven by a motor-operated drum 2 past electromagnetic scanning heads 12, 13, 14 which are driven in a direction parallel to the axis of the drum 2 so that the tape is spirally scanned. The scanning heads may be driven by a lead-screw 16 which is operated through gearing by the drum motor and may be clutched to the common support 15 of the scanning heads; alternatively, spiral grooves may be provided in the tape and co-operate with the scanning heads to cause their transverse movement. The support 15 may also carry a soft pencil &c. which marks the tape and thereby indicates the portion of the tape which is scanned. During recording such marking may be varied automatically and thus provide indications of no-signal periods. The tape is passed over rollers 3, 4, 5, the roller 3 being carried in movable bearings on a lever 9 which may be raised to tighten the tape on the rollers or lowered to permit removal of the tape.
Patent GB-1216765-A (GB)
Title: Refrigeration system for refrigeration units
IPC: F25B1/00
Filed: 1968-04-16
Abstract: 1,216,765. Refrigerating. BATTELLE DEVELOPMENT CORP. 16 April, 1968 [12 April, 1967], No. 17944/68. Heading F4H. A compression-condensation system includes a vapour circuit and a liquid circuit which are each adjustable to vary the quality of the refrigerant in the evaporator and the refrigerant mass flow rate in the evaporator. As illustrated, a main circuit comprises the compressor 1, condenser 2, expansion valve 3, and evaporator 4. The evaporator is provided with a mixing chamber 8 and a separator 5 which are linked by a vapour line 15 and a liquid line 14 to form, with the evaporator, the vapour and liquid circuits. Pumps 6 and 7 are included and the flow rates in the lines 14 and 15 are adjustable. In a modification, Fig. 3b (not shown), the liquid circuit powers a jet pump to cause flow in the vapour circuit. The jet pump and/or a valve in the vapour circuit are adjustable. In an alternative arrangement, Fig. 3c (not shown), the jet pump may be powered by the vapour flow to cause flow in the liquid circuit. In another embodiment, Fig. 4 (not shown), high pressure vapour from a point upstream of the condenser powers a jet pump and then passes to the evaporator mixing chamber. The jet pump draws liquid from the separator to the mixing chamber. In this case the vapour circuit is formed by the evaporator, separator, compressor, jet-pump and mixing chamber. In a further arrangement (not shown), refrigerant flows from the expansion valve direct to the separator and the mixing chamber is fed only by the liquid and vapour lines from the separator.

Title: Improvements relating to wobbler or swash-plate mechanism
IPC: F16H23/06
Filed: 1937-06-28
Abstract: 475,262. Swash plate mechanism. HULSEBOS, W., and NAAMLOOZE VENNOOTSCHAP HULSEMO. June 28, 1937, No. 17970. [Class 80 (iii)] Swash-plate mechanism which includes members provided with surfaces which roll upon one another are formed with co-operating rolling surfaces constituted by an annular rib and an annular groove having a cross-section adapted to fit that of the annular rib. The arm 10 of a wobbler plate is provided with two annular grooves 12, 14 of arcuate cross-section. The shoes or slippers 16, 18 which slide. upon plate surfaces 19, 20 of the piston extension 22 are formed with similar annular grooves 24, 26. Seated in the two pairs of grooves are two hardened steel rings 28, 30, the cross-section of each being circular. Each ring fills the space of circular cross-section where the grooves 12-24 and 14-26 make their closest approach. In a swash-plate construction, the slider 34 moves on the plate 32 and a ring 42 is interposed between it and the piston extension 38, both the slider and the extension having arcuate grooves 36, 40. In a modification, the ring 44 is provided with a central disc 44a with which co-operate spring plungers fitted to the slider 48 and the piston 50. Alternatively, the wobbler 10 may carry a separate piece 62 suitably formed with grooves 12-14 and in place of direct contact with the corresponding surfaces there may be interposed a hardened ring 58 secured to one of the sliders. In another form, the plate 10 may be fitted with a member 68 somewhat like a double hollow rivet, the rounded ends 64-66 of which co-operate with the recesses 24-26 in the corresponding slider parts 16, 18. The projection between the recess may be suitably formed to co-operate with the hollow part of the member 68. Further, these members may be drilled to provide lubricating passages. Specification 350,308 is referred to.
Patent GB-293199-A (GB)
Title: Improvements relating to magnifiers for telegraph signals
IPC: H04L25/06
Filed: 1927-07-06
Abstract: 293,199. Klesel, A. T. July 6, 1927. Systems employing non-contact-making relays. -In a system for amplifying telegraph signals one or more oscillating thermionic valves 5, 6 are arranged so that the signal varies the current in the anode circuits and thus disturbs the balance of a balanced system. The valves are connected in two arms of a balanced bridge, the other arms of which comprise resistances 1, and disturbance of the balance operates a recorder 10. The variation of the anode current is obtained by a simultaneous alteration of the tuning of the grid circuits of both valves produced by a deflection of a telegraph receiving-instrument 25. The moving coil of the receiving-instrument is fitted with a boom 24 carrying a moving plate 23 of a condenser and movement increases the capacity of the grid circuit of one valve and decreases the capacity of the grid circuit of the other valve. Alternatively the plate moves between or above two coils in the respective grid circuits of the valves (Figs. 2 to 6, not shown). According to a modification, only one valve is employed and the effect of the anode current is balanced mechanically, for example by a torque.

Title: Improvements in or relating to concentric conductor electric cables
IPC: H01B13/18
Filed: 1935-06-25
Abstract: 458,772. Cables. STANDARD TELEPHONES AND CABLES, Ltd., and WESTON, W. K., 63, Aldwych, London. June 25, 1935, No. 18170. [Class 36] Slotted insulating discs are continuously applied in spaced relation to the central conductor of a concentric cable from a magazine in such manner that relative longitudinal movement between the discs and the conductor is substantially eliminated during the period that the discs are being forced on the conductor, the latter being supported during application of the discs to prevent bending. The discs may be of a rubber composition, ebonite, polystyrol, or a synthetic resin. The slots in adjacent discs are preferably diametrically opposed. After assembly of the discs, the conductor is passed direct to apparatus for applying the outer conductor which may comprise an extruded tube or copper strips or wires bound together and, if desired, lead sheathed. A machine, Fig. 2, for assembling the discs 2 on the central conductor 1 comprises rotating magazines 3 having solts 4 into alternate ones of which discs are fed from tubes 5 by means of spring-operated, cam-controlled trigger members 10. Capstan mechanism for drawing the conductor through the machine is geared to the magazines to ensure synchronism. In a modification, Fig. 5, the spacing of the slots 4 is double that of Fig. 2, the spaces 4 between the slots being thin to pass through the slots in the discs carried by the opposing magazine: in this form, discs are fed to every slot.
