Abstract: 1,111,410. Determining porosity. GEORGIA TECH. RESEARCH INSTITUTE. March 20, 1967, No, 12862 / 67. Heading G1S. In apparatus for determining the porosity of a specimen 10 of porous material by gas displacement, the specimen is sealed in a flexible envelope 11 which is closed at the bottom by means of a base B which is screwed into a cavity 22, there also being provided a reservoir to hold the gas and valve means 30, 31, 34 to selectively release the gas from the reservoir into either the envelope or the cavity. In use, a pump P is used to evacuate air from within the envelope 11 and the cavity 22, valves 30, 31 are then closed and valve 34 opened allowing air in the column 35 to expand into the cavity 22 so that the envelope 11 adheres to the specimen. The levelling bulb 37 is then raised to bring the pressure in the cavity to atmosphere, the pressure difference being read on scale 44 of a manometer M as a measure of the bulk volume of the specimen. Valve 30 is then opened and the charge in pressure due to air filling the pores of the material is measured on the pore volume scale 45 of the manometer when atmospheric pressure is reestablished. In a modification the manometer is replaced by a comparison chamber and pressure gauge. In a further modification, the specimen and envelope are sealed in a chamber of variable volume which is controlled by a sealing disc moved by a rotatable shaft. In a further arrangement the variable volume chamber is connected through valve control means to a similar control chamber.

Title: Internal combustion engine
IPC: F02B25/22
Filed: 1974-03-22
Abstract: 1464956 Opposed piston type IC engines L E KRAMER 22 March 1974 [30 March 1973] 12871/74 Heading F1B The invention relates to an I.C. engine of the kind having a pair of opposed pistons mounted in a cylinder, the pistons moving apart after firing of the charge which has been compressed between the pistons; towards the end of the power stroke, exhaust ports are opened, then a scavenge air port is opened to discharge the exhaust gases through the exhaust ports, then finally a fuel/air mixture inlet port is opened, the pistons now moving inwardly to compress the charge ready for the next power stroke. The engine shown comprises two cylinders 48, 54 in which are disposed pairs of opposed pistons 42, 66 and 51, 58, the pistons being connected by rods to the crankpins of a pair of crankshafts 29, 31. Each piston is formed with a head portion such as 45 of piston 42 and a compressor portion such as 46 of piston 42. As the pistons 42, 66 move away from each other following firing of the charge which has been compressed therebetween, the piston portion 45 first uncovers the exhaust ports 74, 76; then the piston portion 67 uncovers the scavenge air inlet ports 77 and air which has been compressed by the compressor portion 56 of the piston 51 in the space 81 discharges through duct 88 and the inlet ports 77 to scavenge the exhaust gases through the exhaust ports 74, 76. As the pistons 42, 66 continue to move away from each other the piston portion 67 then opens the air/ fuel mixture inlet ports 78 through which mixture which has been compressed by portion 62 of the piston 58 in space 91 now discharges through duct 96 and ports 78. The pistons 42, 66 now start to move towards each other closing the ports 78, 77 and 74, 76 and compressing the mixture charge therebetween for the next power stroke. As the pistons 42, 66 move away from each other air is drawn in through a non-return inlet valve into the space 101 defined by compressor portion 46 of piston 42, and air/fuel mixture is drawn in through a non-return inlet valve into the space 109 defined by the compressor portion 111 of piston 66. As the pistons 42, 66 move towards each other so the air is compressed in space 101 and subsequently discharged through duct 104 and inlet ports 106 as scavenge air for scavenging exhaust gases from the cylinder 54. Similarly the air/fuel mixture is compressed in space 109 and subsequently discharged through duct 112 and inlet ports 113 as a fresh charge for the cylinder 54. The pistons 51, 58 in the cylinder 54 operate similarly but in the opposite phase.

[Class 82 (ii)] A process for concentrating phosphate ores comprises treating an ore pulp in the presence of a negative-ion phosphate-collecting agent, treating the resulting rougher phosphate concentrate with a mineral acid, preferably sulphuric and thereafter treating it in the presence of a positive-ion silica-collecting agent to yield a final high grade phosphate concentrate. The treatments may be effected by froth flotation, tabling, or other means. The negative-ion agents may be fatty or resin acids and their soaps, naphthenic acids and their salts, sulpho fatty acids and their salts, acid esters of higher aliphatic alcohols and their salts, xanthates etc.; and the positive-ion agents may be higher aliphatic amines and their salts, esters of amino alcohols with higher fatty acids and their salts, higher alkyl-o-substituted isoureas and their salts, resin amines and their salts, higher aliphatic quaternary ammonium bases and their salts, higher alkyl pyridinium or quinolinium salts &c. and particularly dodecylamine or octadecylamine or their hydrochlorides or acetates. Froth flotation with the negative-ion agent, and in some cases with the positive-ion agent, may be carried out in presence of a mineral oil and an alkali, and in either case a suitable frother may be added.

Abstract: 1,128,432. Radial flow gas turbines. WALLACE - MURRAY CORP. Jan. 30, 1967 [April 8, 1966], No. 12999/68. Divided out of 1,128,431. Headings F1G and F1T. An exhaust gas driven turbine assembly for driving the compressor of an internal combustion engine turbocharger comprises a housing having two inlet apertures, a turbine rotor mounted for rotation within the housing, and a single volute passage formed in the housing extending adjacent the periphery of the turbine rotor. A first passage in the housing extends between one inlet aperture and the volute passage, and a second passage extends between the other inlet aperture and the volute passage. A tongue or projection extends into the region where the first and second passages connect with the volute passage so as to prevent entry of exhaust gases to the turbine rotor in that region. Thus the exhaust gases introduced separately into each inlet aperture are caused to flow into the turbine rotor along the length of the volute at a substantially constant static pressure. The invention is described with reference to the embodiment disclosed in Specification 1,128, 431.

Abstract: 892,196. Radar. DECCA RECORD CO. Ltd. April 7, 1960 [April 17, 1959], No. 13217/59. Drawings to Specification. Class 40(7). [Also in Group XXXVI]  The position of a radar trace on a cathode ray tube is controlled by an analogue computer (see Group XXXVI) which interpolates the position of the scanner from sample positions of the scanner taken at short intervals. The position of the scanner is represented by amplitude modulations on two synchronized carrier waves representing respectively the sine and cosine of the position of the scanner with respect to some datum. The carrier waves are coupled at each corresponding peak amplitude and the resultant interpolated output controls the trace. The scanner may also be that of a "rodding beam" height finding radar.
