Abstract: 976,372. Making patterns. G. NEIDL. Dec. 14, 1960 [Dec. 29, 1959; Jan. 15, 1960; Feb. 13, 1960; Feb. 18, 1960; March 26, 1960: April 8, 1960], No. 42963/60. Heading B3F. [Also in Divisions B1 B2, B8 and F1] A pattern for making moulds for casting the volute casing of a centrifugal pump is made by the apparatus shown in Fig. 12, comprising a hollow shaft 78 carrying a pattern generator 79 in the form of a pair of parallel discs, a semicircular gap between the peripheries of the discs being covered by an elastic membrane 84. While the pattern generator 79 is slowly rotated by means of a handle 86, compressed air is introduced through the hollow shaft 78 into the interior of the pattern generator to inflate the membrane 84. Material 87, such as plaster, clay or the like, within a container 75 is thus displaced by the expanding membrane 84 to form a cavity 88 which gradually widens in the manner of a volute. Probes 91, Fig. 14, are then pressed into the material until they are flush with the inside surface 95 of the voluteshaped cavity and are used as guides for trimming the material to a uniform thickness 98. Specification 949,461 is referred to.

Filed: 1964-10-23
Abstract: Papier-mache matrix blanks are suspended vertically and spaced apart on a rectangular grid (7), being separated by a series of horizontal rods (9) in a compartment (1) of a cabinet. Compressed air and water are supplied through valves (18, 19) to nozzles (5) beneath the compartment (1), whereby a mist of water is forced upwards, carried over a vertical wall (4) by air blown horizontally from a duct (21), and downwardly to the blanks, thereby increasing the humidity of the matrices.  The grid rests on weight-sensing devices (8), preferably one at each corner, which actuate an indicator (24) set to a desired humidity and close the valves (18, 19) when said humidity is reached. The blanks are removed through a door in the side or top of the compartment.

Title: Four stroke internal combustion engine
IPC: F02M33/04
Filed: 1974-10-14
Abstract: 1491882 Adjustable IC engine valve gear YAMAHA HATSUDOKI KK 14 Oct 1974 [24 May 1974 26 June 1974 12 Aug 1974] 44379/74 Heading F1B A four-stroke I.C. engine comprising a camshaft 81, Fig. 3, for operating the or each inlet valve 21 and a cam-shaft 82 for operating the or each exhaust valve 22, has means for rotating one cam-shaft relative to the other in dependence on engine load so that when the throttle valve is substantially closed the degree of overlap for which both the inlet and exhaust valves are open is reduced as compared with the overlap during normal load operation of the engine. This enables the engine to be operated at low load with an air/ fuel mixture which is leaner than stoichiometric and thereby reduce the pollutants present in the exhaust gas. The cam-shafts are driven by a chain 85, and the means for rotating the cam-shafts relative to one another comprise a hydraulically actuable tensioner 90. In operation at low loads a valve 97 adlopts the position shown wherein the length 223 of the chain between the cam-shafts is a minimum representing minimum valve overlap. High-load operation as sensed by engine throttle linkage setting or inlet manifold pressure causes the valve 97 to switch to permit pressure fluid from source P to pass through line 97b into a cylinder 92 and force tension member 91 downwardly. Thus the length 223 of the chain increases between the cam-shafts causing relative rotation therebetween. In an exhaust gas recirculation system, the gas passes from a connection (44), Fig. 4 (not shown), through a pair of vacuumoperated valves (46, V) and individual pipes (13ad) to respective cylinder inlet conduits (12a-d), the valves (46, V) being operable in accordance with the degree of vacuum sensed in one of the inlet conduits. The pipes (13a-d) may be provided with non-return valves.

Title: Method for pyrolyzing solid carbonaceous materials
IPC: C10G1/02
Filed: 1962-11-27
Abstract: <PICT:1005359/C4-C5/1> A method of continuously producing a vapour from a solid carbonaceous material, e.g. oil shale, comprises introducing crushed shale, at 2, and hotter heat-carrying solids at 4, 5, into the top of a vertical pyrolysis zone 3 in a non-combustion supporting atmosphere, causing the shale and solids to pass down the zone to produce a vapour which agitates the shale and solids at the top of the zone, removing the vapour from the top, at 9, removing solid shale residue from the bottom, at 6, recovering the heat-carrying solids, at 7, reheating the solids, at 13, e.g. in a pebble heater or in a fluidized bed, and recycling them to the top of the zone 3 there to heat fresh shale continuously added at 2. The velocity of the effluent vapour is controlled by the dimensions of the hyrolysis zone, preferably below fluidization values, although fluidization may occur at the top of the zone, and an extraneous gas, e.g. steam, may be delivered continuously or periodically to the bottom of the zone to loosen material there.  Other carbonaceous materials mentioned are coal, bituminous sands, lignites, brown coal, and peat, and the heat-carrying bodies may be of iron, steel, sand, alumina, ceramic compositions or spent ash, and the weight ratio of bodies to carbonaceous material is 0.2 to 1 to 5 to 1, preferably 0.5 to 1 to 1 to 1. As shown, spent shale and ash leaving via line 7 are combusted in line 13 with air and fuel gas in which the shale and ash are entrained, and hot coarse ash is separated at 14 for recycling to the zone 3 by line 4, hot fine ash, separated at 16, being discarded except for a small proportion, e.g. 5%, recycled at 5.  A cyclone separator 8 removes solids from the effluent vapour and returns it via line 10 to the zone 3 at a point at which little vapour is formed.  Where the heat-carrying bodies are not formed by spent ash, they may be separated from the spent ash by screeing or elutriating and they may be heated by direct or indirect contact with the hot gases and/or hot solids produced by the combustion process before or after separation, and the fuel gas may be the vapour produced at 9. Hot ash discarded at 18 may be used to preheat the combustion-supporting gas going to the line 13, and the gases leaving the separator 16 may preheat raw shale entering via line 2. Pressures of 10 to 30 p.s.i.a., specifically 16.5 p.s.i.a., and residence times up to 10 minutes, specifically 3 minutes, in the zone 3, are mentioned.  The hot ash delivered at 4, 5 is at 1450 DEG  F. and the vapour and solids leaving respectively at 9, 6 are at 870 DEG F.

Abstract: 1,030,785. Electrically-heated coffee percolators. PHILIPS GLOELAMPENFABRIEKEN N.V. Nov. 15, 1963 [Nov. 20, 1962], No. 45213/63. Heading H2H. A coffee percolator comprises a reservoir 1 provided with an electric heating element 3 connected in series with a positive temperature coefficient resistor 4 which automatically reduces the current through element 3 at a predetermined reservoir temperature, the circuit arrangement being generally similar in design and operation to that described in Specification 1,017,636. Alteration of the operating point of resistor 4 on its appropriate V/I characteristic, Fig. 2 (not shown), is arranged to occur when substantially all of the heated water in reservoir 1 has been driven into the vessel 2, the subsequent drop in reservoir temperature allowing the liquid coffee extract to return thereto where it is maintained at a desired temperature by suitable choice of the resistor V/I characteristics. For a constituent extracting process other than coffee percolating and requiring restoration of the liquid extract to a high temperature after its return to the reservoir, standard resistors may be connected in parallel or in series with the element 3 and/or the resistor 4 to obtain a desired characteristic and/or load line to cause the operating point of the resistor 4 to return to its former value after a period of cooling, thus allowing the current through the element 3 to regain its former high value.

Abstract: 1282282 Die sets BRITISH AERO COMPONENTS Ltd 5 Nov 1969 [27 Sept 1968] 46128/68 Heading B3W A die set comprises a blanking punch 16, a die 39, a stripper plate 25 resiliently mounted through spring assemblies 19 on a base 10, an ejector 49 resiliently mounted through spring assemblies 42 on top plate 13, abutment pins 28 mounted in the punch holder 16 and slidable in the stripper plate and pins 48 mounted in a housing 37 secured to the top plate for engagement with pins 28 as the die set closes. Metal strip 27 fed into the die set is guided by rollers 26. When in use the pins 28 and 48 are pressed against each other. First the pins 48, sliding in housing 37, push a backing plate 41 against the spring assemblies 42 thus relieving the spring load exerted through pins 51 on the ejector 49, the strip being held between the die 39 and the stripper plate. As the die set closes further the stripper plate is depressed, Fig. 6, the punch 16 enters the die aperture and a blank 52 is punched out. As the die set opens the stripper plate first rises due to the spring assemblies 19 removing the strip from the punch, the blank 52 being retained in the die aperture. With further opening of the die set, the pins 48 fall, their flanged heads dropping into recesses 37a in the housing 37 thus lowering the backing plate 41 and allowing the springs 42 to re-apply their load through pins 51 to the ejector 49. To produce a central hole and three holes equispaced from the central hole and each other in the blank 52, punches 46 and 47 mounted in the die 39 co-operate with apertures 17 and 18 respectively in the punch 16.
