Patent GB-592601-A (GB)
Abstract: 592,601. Mechanical stoking apparatus. HEWERDINE, W. H. March 21, 1945, No. 7169. [Class 126] [Also in Group XXX] Stoking apparatus comprises hopper 1 containing fuel crushing means such as movable toothed plate 37, Fig. 11, and feeding means, e.g. pusher 8, operated by hand lever (or pedal) 17 for feeding fuel to a firegrate. In Figs. 1 and 4, handle 17 moving in bearings 10 rotates parallel arms 13b and through connecting bar 15 oscillates pusher 8 in casing 2. In the latter is opening 2a, through which coal enters from hopper 1. Pins 30 on pusher 8 move in slotted arms 27a of slide plate 27, Fig. 8, so that at each end of its stroke the pusher displaces slide plate 27. Levers 29 pivoted at 32 are connected by links 25 to bellcrank levers 26 pivoted at 28 and connected by link 24 to fence 22. Displacement of plate 27 by pins 30 causes fence 22 to be lowered against springs 23 through movement of lever 29. The fence drops on to the pusher as the latter nears the end of its movement to the right, drops through holes 2c to close the end of the casing 2 as the pusher begins to move to the left and, as the pusher moves over to the extreme left and after coal has dropped from hopper 1, is raised by the springs so that the pusher is ready for another stroke. In hopper 1, Fig. 11, is fixed toothed plate 36 and movable toothed plate 37, the latter pivotally connected at 41 to levers 38 fulcrumed at 39 which, Fig. 4, by means of levers 45, are oscillated by movements of the handle to crush coal before it drops in front of the pusher. The coal, Fig. 1, passes through conduit 3 into the firepot 4 from underneath. Draught inducing screen 46, made in two parts 46a, 46b, Fig. 12, may be operated by handle 49 which actuates lever 48 having roller 50 moving in horizontal slot 51. Handle 17 may be spring-operated in one direction.

Abstract: 1501370 Camouflage material HOECHST AG 27 Dec 1972 [5 Jan 1972] 59682/72 Heading D1B Camouflage material is made by pigmenting synthetic fibres, sheets or films with carbon black and then cross-dyeing or cover printing the material with a dyestuff appropriate for camouflage in the visible range of the spectrum. The material is useful for camouflage both in the visible and infra-red ranges. In Examples, polyester, polyamide or regenerated cellulose fibres are spun-dyed with carbon black and then dyed an olive or khaki colour with mixtures of specified disperse, acid, metal complex, or reactive dyestuffs. In Example 7 the material dyed is cellulose acetate foil containing titanium dioxide and carbon black.

Abstract: 1335853 Woven fabrics K T KUNSTSTOFFTECHNIK GmbH 23 Dec 1970 [29 Dec 1969 29 July 1970] 61042/70 Heading D1K [Also in Division B5] A woven fabric incorporates hollow inflatable tubes 1 either as warps or wefts, and after weaving a settable compound is applied to the fabric and allowed to set with the tubes inflated. The warp or weft may consist entirely of tubes, or conventional threads may be woven as warps with the tubes, Fig. 2 or form plies above and below the tubes which act as stuffers, (Fig. 3, not shown) or be woven as separate warps between the tubes (Figs. 5 and 6, not shown). The fabric may be woven in the form of a tube (Figs. 12 and 13 not shown) with the tubes 1 extending in the longitudinal direction. The threads woven with the tubes may be glass filaments. The inflation of the tubes may be produced by including in them material which can be processed to expand, as round or flat tapes, (Fig. 16 and 17) which may be disposed in separate ducts which rupture to connect with the main tubes an expansion of the material, (Figs. 18 and 19), or as a coating on the insides of the tubes (Fig. 17). Three tubes may be incorporated between adjacent weft crossings (Figs. 14 and 20). After setting of the compound layers of material (7) Fig. 11 (not shown) may be applied to either side of the fabric to produce an insulating layer.

Abstract: 1293570 Microtomes INCENTIVE RESEARCH & DEVELOPMENT A B 16 Dec 1969 [16 Dec 1968] 61334/69 Heading G2J In a microtome comprising a specimen holder 8 for a specimen 9, which reciprocatingly moves relative to a knife 7, a tape 18 passes above the specimen and is pressed against the specimen during cutting for application of the latter thereto. The knife 7 is indirectly mounted on a support member 4 upon which moves a reciprocating  carriage member 5 driven by a pneumatic or hydraulic cylinder 14 or by an electric motor. The tape 18 is pressed against the specimen by a vertically moving brush 29 driven by a pneumatic or hydraulic cylinder or by a solenoid and is fed between a supply roll 16 and a one-way rotation collecting roll 19 mounted on the carriage member, by pulley 24, rope 25 and weight 26. Rollers 32, 33 supported on a fixed post 31 and actuated by a pneumatic or hydraulic cylinder or by a solenoid 34, clamp the tape during the return stroke of the carriage member 5. The cylinder 14, brush 29 and the feeding of the tape are controlled by a control unit 38, Fig. 2 (not shown). Between cutting strokes the specimen 9 can be raised incrementally by a screw 10 and gear-wheels 11, 12 driven by a stepping motor 13. Fragments of the specimen produced during cutting are sucked through a nozzle 37 and a tube 36 by a fan (35). To enable freeze-drying of the collected specimens a roll 46 may be provided to supply a band 47, e.g. of loose net or fabric, that becomes interposed between the turns of tape 18 to permit air circulation. Micro-switches 39, 40 indicate the end positions of reciprocating member 5 and micro-switches 42, 43 the times of lowering and raising the brush 29, the switches being actuated by a cam 41. A switch 44 operated by a cam 45 determines the suction time of the fan (35). Additional switches may be provided e.g. to stop the microtome if the tape 18 breaks. The microtome may have a refrigerator (3) and be enclosed within a heat insulated casing 1.

Patent GB-2020363-A (GB)
Title: Rotary compressor
IPC: F04C28/06
Filed: 1979-06-13
Abstract: A compressor of the sliding- vane eccentric-rotor type is provided with a vacuum operated valve (189) controlling a passage (185) leading from an oil separator (172) to a suction port (110) controlled by an unloader valve (120). When the unloader valve (120) is closed it causes a reduction in the pressure in suction port (110) which is applied through passage (197) to the diaphragm (190) of the vacuum operated valve (189) thereby enabling compressed gas to be by-passed from a chamber (157) to the suction port (110) through the passage (197). The vacuum operated valve (189) additionally provides a permanent leak path to drain the oil coalescing in the separator (172) back into the chamber (157) through the suction port (110). <IMAGE>

Title: I.c. engine with reciprocating and rotating piston
IPC: F01B3/00
Filed: 1979-07-27
Abstract: The piston 6 of a two-stroke i.c. engine has a cam groove 8 which co-operates with cam-follower 9 mounted in the wall of cylinder 1. The piston has female splines which engage male splines on a shaft 5 to which is fixed a bevel gear which drives an output shaft. A fuel-air charge is compressed under the piston, transferred through reed valve 4 to chamber 3, passes into cam groove 8 and from there into chamber 15, which at T.D.C. of the piston is isolated from chamber 14 by a spigot which forms part of igniter 16. The partly burnt gases are exhausted through tangential ports 13 in the piston and react against the piston to impart rotary motion to it. The gases pass into collector port 17 and are fed to nozzles 18 which direct the gases on to vanes 19 on the piston crown to further assist its rotation. The gases then expand in chamber 14, to drive the piston downwardly in the cylinder and are finally exhausted through port 20.   <IMAGE>
Patent GB-2055501-A (GB)
Title: Video tape recording apparatus
IPC: G11B5/588
Filed: 1979-08-03
Abstract: A video tape recording apparatus is arranged to replace every (or every n<th>) vertical synchronising signal of a video signal to be recorded, prior to its reaching a recording head of the apparatus, with a modified vertical synchronising signal comprising an initial long pulse (S1) and a series of short pulses (S2). The voltage pulse resulting from integration of the modified vertical synchronising signal has a lower energy content than that resulting from integration of a standard vertical synchronising signal, but has a fast rise time due to 'lumping' of the energy at the start. The voltage pulse peak amplitude exceeds the trigger threshold voltage VTV of circuitry of most TV monitors, whereby a tape recorded on the apparatus can be satisfactorily played back. However, the voltage pulse peak amplitude does not attain the trigger threshold VVTR of a typical video tape recorder (VTR), whereby a tape produced on the apparatus cannot readily be satisfactorily copied on a VTR. <IMAGE>
