Title: Occupant restraint system
IPC: B60R21/263
Filed: 1974-02-07
Abstract: 1408530 Discharging gases GENERAL MOTORS CORP 7 Feb 1974 [12 Feb 1973] 05632/74 Heading F4P, [Also in Divisions B7 and F1] In an occupant restraint device in which a cushion is inflated at a relatively high or a low rate from a combution chamber 36, a ballistic element 86 is fired, in response to relatively high velocity impact conditions into an orifice 76 to reduce its area and thereby increase the pressure within the chamber for increasing the burning rate of matter 72 therein for inflation of the cushion through the orifice 76 at the relatively high rate. As shown in Fig. 1, under low velocity impact a squib 82 is fired via electric plug 94 igniting mass 72 so that high pressure gas produced in plastic cartridge 60 eventually severs a diaphragm 48 along grooves 44, 46, and a diaphragm 20 of pressure vessel 12 is severed, via rod 50, along grooves 16, 28. The vessel 12 contains a pressurized gas such as argon. Thus gas from chamber 36 mixes with gas from pressure vessel 12 to inflate the cushion through openings 28 and manifold 32. Under high velocity impact however the squib 84 is fired to explosively fire ball 86, retained in a bore 70, through the combustion chamber 36 into engagement with orifice 76 of a plate 74. The ball deforms as it engages ribs 106, Fig. 4, of orifice 76 to thereby reduce its area. Gas can only now flow through flutes 78 to thus increase the pressure in chamber 36 and hence increase the burning rate of mass 72. A peripheral groove 108 in chamber 36 allows its end portion to be severed off in case of pressure within rising above a set level. A modified orifice plate comprises a fluted tapered bore, Fig. 7 (not shown) which receives the ball 86 to reduce the orifice area of the plate.

Filed: 1940-03-30
Abstract: 540,094. Furnace walls. DETRICK CO., M. H. March 30, 1940, Nos. 5747 and 5748. Convention dates, April 22, 1939 and Oct. 18, 1939. [Classes 51 (i) and 51 (ii)] The walls of a furnace are formed of a number of vertical steel frame members 11 joined by supporting members 12 to form a skeleton frame which is first erected by steel workers before applying the inner refractories 18. These refractories 18, which are constructed as shown in Fig. 4, are supported in sections with the members arranged in staggered form, each section being supported by a main hanger 41 suspended by a hook portion 42 from a supporting frame 12 which is formed with a recess to receive the hook. The hanger 41 is formed with a flange 45 which supports the refractories 18 and with lugs 46 which engage grooves 27, 29 of adjacent refractories, or engage a central groove of a single refractory, the flange 45 supporting recessed parts 31, 33 of adjacent refractories or a single recess 32 only, so that in either case the extent of the supporting surface is slight. In addition to the hanger 41, an auxiliary hanger 51 is used for each section and is removably mounted on a frame member 12 in vertical alignment with the hanger 41 and supports retaining members 61 formed with flanges 64 which engage grooves 26, 28 in adjacent refractories to prevent outward bulging of the wall. The refractories are formed with interengaging grooves 35 and projections 34, and an expansion joint 66 is provided between the wall sections. After the refractories have been built up the space between them and the frame members 12 is filled up with insulation blocks 67, and blank spaces are filled in with plastic insulation material 68 which may be backed by metal plates 63 and batten strips 73 secured by bolts 72, and nuts 74 to the auxiliary hangers 51. In a modification the outer metal plates 69 are dispensed with and replaced by a layer of hard weather-proof plastic. The shape of the frames 11 and the hangers 41, 51 is varied so as to to form retaining means for the plastic material which when finished off gives a final appearance superior to that of the first form.

Abstract: 1,216,811. Lasers. NIPPON ELECTRIC CO. Ltd. 3 Feb., 1969 [2 Feb., 1968; 27 Feb., 1968; 26 July, 1968; 16 Nov., 1968], No. 5773/69. Heading H1C. A pumping arrangement for a laser rod comprises an internally-reflective hollow spheroid 10, Fig. 1, of which at least two sections XY, XZ, YZ has respective foci equally spaced from the centre of the spheroid, the laser rod and an elongate light pumping source of substantially the same effective length being symmetrically located in one section with respect to the spheroid centre. In one arrangement, Figs. 2 (a) and 2 (b) the spheroid has diameters 2a, 2b, 2c different for each section, the laser rod 11 and a straight light pumping source 12 being located in section XY in such positions that they pass through respective foci F1, F1<SP>1</SP> of section XZ. A prolate spheroid is shown in Figs. 3 (a) and 3 (b), and since the section XZ is circular and has but a single focus the laser rod and light pumping source are positioned as close to each other as possible. Figs. 5 (a) and 5 (b) show an oblate spheroid in which the laser rod and the light pumping source are located in section XY and pass through the foci F, F1 of section XZ. In this arrangement increased coupling between the pumping source and the rod may be obtained by forming the pumping source with a convex curve, Fig. 6 (not shown). The spheroid may be formed of metal or metallized glass and the pumping source may be an arc or filament lamp.

Title: A process for removing acid components from crude gases
IPC: C07C7/11
Filed: 1963-02-14
Abstract: A process for removing acid components, e.g. CO2, H2S, from crude gases comprises washing the gas with an inorganic alkali liquor, e.g. an aqueous NaOH or KOH solution, which is being or has been treated with one or more organic solvents which are substantially immiscible with water.  Crude gases are obtained from cracking and refinery gas, and the organic solvents may be condensed organic components from the crude gases. Other solvents mentioned are liquid hydrocarbons, e.g. cracked gasoline or fractins thereof, benzene, toluenes, xylenes, and ethers, ketones, and chlorinated hydrocarbons, e.g. diethyl ether, chlorobenzene, and carbon tetrachloride.  The solvents may amount to 5 to 20% by volume of the alkali liquor.  The liquor may be circulated in counter-current to the gas through a washing tower, and the solvent forms a layer on the liquor which forms a sump at the bottom of the tower, gas entering the bottom of the tower at a point above the solvent layer.  Some of the solvent may be recycled, or it may be introduced at the top and withdrawn at the bottom of the tower.  Alternatively, the solvent may be kept outside the tower, and the liquor passed therethrough during recycling.  The solvent may be in gaseous phase, e.g. where the crude gas supplies the solvent, condensation, e.g. of C3 . . . C5 hydrocarbons, occurring in the tower, the temperature of the liquor being adjusted outside the tower to be cooler than the gas. Solvent may be withdrawn continuously or intermittently for purification.  Five specific examples are described, using cracked gasoline as the solvent.

Abstract: 661,576. Linear-dimension gauges; indicating-apparatus. NEMECKY, M. March 7, 1949, No. 6155/49. Classes 106 (ii) and 106 (iv). A gauge comprising a pointer or mirror connected to a shaft to which rotational movement is imparted by a fibre wound round the shaft and movable in correspondence with the value to be measured is characterized in that the shaft is carried by two systems of fibres wound round the shaft in opposite directions without being fixed thereto while at least one system is movable by the member, the displacement of which is to be measured, whereas the other is stationary or movable by the said member in the opposite direction. An indicator shaft is supported by at least two systems of fibres wound in opposite directions round the shaft and is actuated by longitudinal displacements of at least one system, the other system moving equally and oppositely so that the shaft is not laterally displaced or the other remaining stationary when the shaft will be slightly displaced. The fibres may form a straight line as they leave the shaft on either side or they may lie at an angle to each other. The actuating fibres are attached directly to a displaceable member on one side of the shaft and through a spring to a fixed part on the other side, while the other system may be fixed directly to fixed parts on both sides or through springs. The actuating fibres may, after leaving the shaft, pass round a pulley on a fixed bearing and return to wind oppositely round the shaft to form the other system. A gap gauge, Fig. 4, embodying the invention, comprises arms D, D1 pulled inwards by a spring q and carrying frames r2, r1 which support fibres v1, v2 wrapped in opposite senses round a shaft y for a pointer u which indicates the distance between end points d, d1. A dial gauge, Fig. 7, embodying the invention, comprises a plunger slidable in a casing m, pulled down by a spring x and stopped by a pin n. Movements of the plunger are indicated on a scale c by a pointer u fixed to a shaft h actuated by fibres v1, v1<SP>1</SP> wrapped round the shaft h and attached to two pins b in the plunger spindle.

Title: Improvements relating to electric resistance melting furnaces
Inventor: STEINHOFF EDUARD
IPC: C03B5/033
Filed: 1956-02-28
Abstract: 820,947. Electric melting furnaces. DIDIER-WERKE A.G. Feb. 25, 1956, No. 6234/56. Class 39(3) A furnace for melting quartz sand into fused quartz is heated by horizontally spaced resistance rods 3 e.g. of graphite over and between which the sand flows down, and each rod 3 is screened from direct contact with the sand by an individual cover 4 extending over the entire length of the rod. The covers 4 may be tubes of circular or oval section spaced from the surface of the rods, but may leave the lower part of the rods exposed and when non-conductive may contact the rods. The covers 4 carry substantially no heating current and may be of refractory non-metallic material e.g. oxides, nitrides or borides of zirconium or titanium or carbides e.g. silicon carbide. Each cover may have a protective layer e.g. of silicon carbide; and when the cover is of graphite, in which case it is insulated from the rod 3, this layer may be formed in the furnace. Each cover may be formed with an upper longitudinal rib extending its whole length. The covers may be of undular form in longitudinal section, may have transverse external ribs and grooves and may be formed with skirts 5 extending down on each side far enough to prevent the melt from contacting the lower side of the rod 3. The skirts are serrated at their lower edges. Any gas formed in the melt-free zone 7 around and beneath the rod 3 e.g. carbon monoxide, silicon, silicon monoxide or silicon dioxide is removed by passing an inert gas e.g. nitrogen through this space from one end to the other. The melting operation is continuous.
