Title: Improvements in or relating to friction linings for brakes, clutches and the like
IPC: F16D69/02
Filed: 1954-01-22
Abstract: A moulded material for friction linings for brakes, clutches, &c. consists of a fibrous material and a binding agent with or without fillers, and molybdenum disulphide homogeneously dispersed therethrough, in amount, e.g. of 0.1 to 10 per cent by weight of the material.  The binder is preferably a mixture of 5 parts (by weight) of natural rubber and 3 parts of a thermosetting phenol-formaldehyde resin.  In the example, two cold solutions of natural rubber and asphaltic bitumen (as plasticizer) in trichlorethylene are mixed together; the fillers carbon black, graphite, sulphur and litharge are then stirred in, followed by the molybdenum disulphide and chopped wire yarn (i.e. asbestos and cotton-covered wire) and finally by the phenol-formaldehyde resin. The resulting paste is extruded in the cold, and after alternate drying and compressing operations is moulded into the desired shape and baked.ALSO:A friction lining composition consists of a fibrous material and a binding agent with or without fillers, and molybdenum disulphide homongeneously dispersed therethrough in amount, e.g. of 0.1 to 10 per cent by weight of the composition.

Title: Water drainage valve for compressed air installations particularly  compressed  air brake systems in motor vehicles
IPC: F16T1/14
Filed: 1974-01-16
Abstract: 1452983 Apparatus for releasing liquid from compressed air systems GRAUBREMSE GmbH 16 Jan 1974 [8 March 1973] 02133/74 Heading F4U [Also in Division F2] A valve assembly for automatically draining water from a compressed air brake system comprises a valve body having a flat plate-shaped cover 1 with screw threads 3 for attachment to the system and a valve seat 4 through which the water drains. The disposition of threads 3 is such that, when installed in the system, substantially the entire valve assembly is protected from damage. In one arrangement, Fig. 1, a moulded plastics part 8 is sprung into engagement with the upstanding rim 2 of metal cover 1. Part 8 has a central extension 11 containing a filter 12 and is joined to a further plastics part 14 forming an accumulator chamber 18. In operation, compressed air and entrained water from the system enter the valve assembly through a transverse recess 15 in part 14 and through gaps between parts 8, 14 and thence flow through filter 12 into a chamber 16 which is closed by a stressed diaphragm 10 seating at 9 on part 8. When the air pressure is sufficient, diaphragm 10 unseats from the latter permitting air to fill chamber 17 and accumulator 18 connecting therewith through ducts 19. Diaphragm 10 remains urged against seat 4 by system pressure in chamber 16. Should the latter now fall, e.g. as a result of brake application, relative to the pressure in accumulator chambers 17, 18, diaphragm 10 seats at 9 but unseats from 4 permitting water trapped in chambers 17, 18 to be ejected through nozzle member 5. Seat 4 remains open until the pressure in chambers 17, 18 has fallen to that in chamber 16. To permit water drainage to be effected manually nozzle member 5 is supported in cover 1 by an elastic collar 7 so as to be movable inwardly under finger pressure to unseat sealing rim 6 on the nozzle member from cover 1. In a modification, Fig. 3, the valve assembly has a similar external configuration but contains a ring-shaped hollow float 21 which is coupled by levers 23 to a valve stem 22 passing through the centre thereof. Thus water entering at 24 causes float 21 to rise and lift stem 22 off seat 4 to permit the water to be ejected.

Title: Improvements in or relating to circuits for flash discharge tubes
IPC: H02M3/338
Filed: 1969-01-14
Abstract: 1,249,041. Flash discharge tube circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 14 Jan., 1969 [17 Jan., 1968], No. 2174/69. Heading H2H. [Also in Division G3] A circuit for supplying a flash tube includes a capacitor which is charged from an oscillator and maintained at a substantially constant voltage by an arrangement including a breakdown element and a semi-conductor switching device. In the circuit of Fig. 1, the capacitor 10 is charged from a D.C. source 2 by way of an oscillator including transistors 7, 8. When the voltage on the capacitor reaches a predetermined value, a glow-lamp 17 breaks down and terminates the operation of the oscillator. A transistor 16 also becomes conductive at this time, shorting a resistor 14. The capacitor slowly discharges until the lamp 17 extinguishes, when charging recommences. The ratio of maximum to minimum voltages on the capacitor is close to unity due to the shorting of the resistor 14 even though the lamp 17 remains conductive at a voltage appreciably lower than its strike voltage. A switch 25, which may be on a camera, discharges the capacitor through a triggered flash tube 1. In an alternative arrangement, Fig. 2 (not shown), a normally conducting transistor is connected in series with the glow-lamp. When the lamp strikes, the transistor is blocked and a further resistance is placed in series with the lamp to lower its voltage and advance its extinction in the same way as in the first embodiment. The glow-lamp may be replaced by a diac, and the transistor 16 could alternatively be a thyristor or triac.

Title: Coal hydrogenation
IPC: C10G1/08
Filed: 1965-01-18
Abstract: Coal is converted to hydrocarbons by flowing in pulverized form suspended in a hydrocarbon in the liquid phase with hydrogen through a bed of particulate, preferably catalytic, solid having at least one dimension of at least 1/32 inch at an upflow rate to expand the solid by at least 10% without substantial carry over at 1000-4000 p.s.i.g. and a temperature and space velocity such that conversion of carbon in the coal is at least 50%.  The hydrocarbon liquid is preferably part of the product used in an amount about equal in weight to the coal.  The coal throughput may be 15-150 lb./hr./cub. feet of reactor space and the temperature 750-950 DEG F.  The catalyst, e.g. Co, Mo, Ni, Fe or Sn on alumina, magnesia or silica, is expanded to not more than twice its volume by using a flow rate of 5-120 U.S. gallons/min./sq. foot of horizontal cross-section, recycling product to maintain this rate. The effluent is separated into hydrogen for recycle, gas, naphtha, fuel oil and a slurry of solids in oil which is passed to the top of a three-stage reactor into the bottom of which oxygen and steam are introduced.  At 1700-2000 DEG  F. and 400-600 p.s.i.g. a hydrogen-carbon monoxide gas is obtained which may be subjected to water gas shift to obtain hydrogen for use in the hydrogenator.

Patent GB-489616-A (GB)
Title: Improvements in or relating to artificial filamentary materials
IPC: D01D5/00
Filed: 1937-01-28
Abstract: <PICT:0489616/IV/1> Artificial filamentary materials having the form of narrow ribbons are obtained by extruding under pressure a fine stream of spinning solution, receiving the stream on a supporting surface while still so fluid that by its contact with the surface it assumes under gravity a flattened cross-section and causing the stream of spinning solution to set so as to retain the flattened cross-section.  The spinning solution may consist of cellulose acetate, cellulose nitrate or other derivative of cellulose dissolved in an appropriate solvent, or it may be a viscose or cuprammonium solution to give a regenerated cellulose product. Spinning solutions of gelatin, synthetic resins, or latex may be employed.  Setting of the fluid stream on the supporting surface may be effected by evaporation of a volatile solvent or by means of a precipitating liquid.  A plurality of streams of spinning solution may be extruded simultaneously.  The nozzles may be of circular cross-section or shaped so as to assist in imparting the desired flat cross-section of the filaments.  In the case of cellulose derivative products, the spinning solution may contain a plasticizer or a plasticizer may be applied to the supporting surface at a position in advance of the stream of spinning solution.  As shown in Fig. 3, spinning solution is fed by a pump through pipe 1 to the chamber 3 and thence through spinning orifices from which it emerges in fine streams 5.  The streams 5 are received on a highly polished metal casting band 6 and become flattened by gravity.  The flat filaments become hardened by evaporation as they travel on the band.  They are passed from the band to roller 15 and collecting rollers 16.  Specification 463,567 is referred to.

Abstract: 557,753. Aircraft undercarriages. DOWTY EQUIPMENT, Ltd., and BASTOW, F. Feb. 27, 1942, No. 2636. [Class 4] A castoring landing element mounting of the kind in which the landing element is carried by a lever pivoted to a leg and controlled by a shock-abosrber acting between the lever and the leg, is provided with means, independent of the shock-absorber, for damping shimmy by displacing liquid through restricted passages. In one form a wheel is mounted on a lever 10 pivoted to a bracket 8 at the lower end of the leg, a shock-abosrber 11 working in tension being connected to the lever and the leg. The bracket 8 is mounted at the end of a tube 7 rotatable within a fixed tube 6 having a centring cam 17 fixed within its upper end. The cam 17 co-operates with a cam 18 on a piston working within the tube 6 and normally pressed upwards by a spring 23. The piston has an extension sleeve 18a sliding over a splined sleeve 19 pinned to the tube 7. Restricted passages for liquid completely filling the chamber formed by the upper part of the tube 6 are formed in the piston and some of them are controlled by valves ensuring a greater resistance to separation of the cams than to their approach. Relief valves which open under excessive shock also are provided. Fig. 3 shows another form in which a shock absorber 35 acts on the trailing lever 40 between the landing wheel and the pivot 41 of the lever. A cam 45 is fixed to an outer tube 43 secured to the airframe, and a tube 37 carrying the trailing lever and shock-absorber rotates within the tube 43. A cam 46 co-operating with the cam 45 is keyed to but slidable upon a sleeve 50 fixed to the tube 37 and is integral with a piston 48 working in a space 51 containing liquid. Passages through the piston are controlled by a washer having smaller passages so as to offer greater resistance to separation than to approach of the cams which are urged together by a spring 47.

[Class 80 (iv)] Consists in means for preventing injury to operators working on hollow rotating cylinders, e.g. printing machine cylinders, having gaps in their cylindrical surfaces. The cylinder, Fig. 1, has a printing sector 7 and a balancing sector 8 supported by webs 9 from a hub 10. Gaps 11 extend longitudinally between end discs 12, Fig. 4, and these usually accommodate clamps 15 for gripping the end margins 17a of a printing plate 17, on the sector 7. To prevent entry of the operator's hands or fingers into the gaps 11, segmental guard plates 19 are provided which are slidable in channels 20 secured by screws 21, and have finger holes 22 therein to facilitate their opening. Each guard plate is urged to its closed position by a spring 23. Attached to each end disc 12 is a bracket 24 through which passes the stem 25 of a spring-loaded detent 26 which, when the guard is closed, presses against the interior thereof,.but when it is open the detent is forced outwardly by a spring 27 (right-hand. side of Fig. 1), to hold it in the open position. A tripping element 29 mounted on a fixed part 28 is adapted, on rotation of the cylinder, to force the detent inwardly to allow the guard plate 19 to act on its bevelled face under the pull of the spring 23 to still further depress it to permit the guard to close. In a modification, the springs instead of acting directly on the guards, are connected to telescopic rods pivoted to the hub and to the guard. Specification 532,931 is referred to.
