Abstract: 1,110,829. Cold separation of gas mixtures. PETROCARBON DEVELOPMENTS Ltd. 8 Nov., 1966 [29 Nov., 1965], No. 50546/65. Heading F4P. In separating low boiling impurities such as oxygen, nitrogen, methane and ethane from compressed carbon-dioxide by rectification in a column 18 having boiling coils 17, 30 and a reflux condenser 36, the latter is cooled by an external refrigerant forced by a compressor 24 through a water cooler 26, an expansion valve 31 and the condenser 36 back to the compressor 24, and coils 17, 30 are warmed respectively by feed compressed carbon-dioxide and by a portion of refrigerant leaving compressor 24 and an expansion valve 28; the 20 cooled refrigerant then being expanded at a valve 32 and added to the refrigerant flow into condenser 36. Pure product liquid carbondioxide is withdrawn from the column through a line 22 whilst gaseous effluent withdrawn through a line 23 is first used to cool feed gas in an exchanger 15 and then a portion is heated at 12 and used to purge alternating watervapour absorbers 11.

Abstract: 1, 035, 330. Electrostatic precipitators; filters. NIHON GENSHIRYOKU KENKYUJO. Dec. 23, 1963 [Dec. 28, 1962], No. 50696/63. Headings B1D, B1T and B2J. [Also in Division G6] Combustible waste material contaminated with radio-active material is destroyed in afurnace the exhaust gases from which are first centrifuged to remove the larger particles and are subsequently passed through an electrostatic precipitator followed by a cloth filter. Before centrifuging the gases are sprayed with a sodium hydroxide solution and after centrifuging the gases are cooled to precipitate moisture. The ash from the furnace is swilled out with water and conveyed with the solids from the centrifuge and the moisture collected by the cooler to waste collectors. The electrostatic precipitator is shown in Fig. 4 and comprises a row of discharge wires 31 tensioned by stirrup weights 37 astride a steadying bar 38. The collecting electrodes 41, 41a, are comprised by aluminium foil sheets unwound from spools at the top of the precipitator and wound on to spools at the bottom so as to collect the precipitate for disposal with the bottom roll. The filter comprises a length of cloth 63, Fig. 8 (not shown), suppliedfrom one spool and wound onto another for disposal and threaded between alternate inlet and outlet frames 60 and 60a. The frames comprise square-sectioned pipes formed into squares with apertures along their inner edges and are clamped with the cloth sheet between them by pressure plates 58 and 59. Gas admitted through the inlet frames is passed through the cloth for extraction by the adjacent outlet frames. To allow for the cloth to be wound on the spools to provide fresh filter surfaces, the frames are mounted on springs 57 so that they release the cloth when the pressure plates 58 and 59 are released.

Nested cups 13, retained in a magazine 12 by a stop pin 14, are extracted one at a time by a suction head 11, which is adapted to engage the wall of the cup. The suction head is movable by a pneumatic ram 6, 7 on a slide 2 which is movable on guides 3 by a pneumatic ram 4, 5. In operation, the suction head is first moved into the interior of the lowermost cup by retracting the ram 6, 7, is then moved into engagement with the wall of the cup adjacent the pin 14 by retracting the ram 4, 5. The ram 4, 5 is then extended, thereby deforming the cup adjacent to the pin 14, Figs. 4, 5 (not shown), and the ram 6, 7 is extended to remove the cup from the magazine. In a modification, Fig. 6 (not shown), the suction head, instead of being connected to a source of vacuum, is itself constructed as a reciprocating pump having a piston 15 and a connecting rod (16) which couples the piston to the moving mechanism for the suction head.

A tape-cable connector comprises two members 1 and 2, one of which carries a series of toothed contactors 8, the members being so shaped that when they are clamped together with a cable between them, the latter is pulled against the contactor teeth which plough into the insulation of the cable and make contact with its strip conductors. The second member 2 carries a clamping bar 5 to clamp the tape cable firmly to it, the bar being accommodated in a groove 6 in the first member. Between the clamping bar and the contactors, the second member has a depression 14 and the first member a corresponding enlargement so that, as the first and second members are drawn together, the cable is drawn inwards thus causing the teeth of the contactors to bite into the cable. Spring projections 12 are arranged opposite the contactors 8 and to prevent them biting right through the tape cables, or a facing of a material softer or more resilient than the metal of the cables, but harder or less resilient than the plastic insulation of the cable, may be provided. The connector may be used to make tapping connections to a cable, or a double connector may interconnect the ends of two tape cables.

Filed: 1971-11-06
Abstract: 1414774 Valves UNITED GAS INDUSTRIES Ltd 12 Jan 1973 [6 Nov 1971] 51686/71 Heading F2V An inlet valve for a gas manifold has a set of apertures in the closure member 16 to provide more than one rate of gas flow to an appliance to be controlled. The member co-operates with a seat 13 at the lower end of a housing 11 and is connected to a spindle which passes through a bore 18. Rotation of the member by a detachable lever engaged in a connector rigid with the valve spindle enables either four apertures 19 to be brought into register with the seat for normal operation or a single aperture 20 for economy operation. A cap on the end of the spindle allows the disc to be separated by axial movement from the end of the housing to boost the flow. The number and diameter of the apertures may be altered for use with natural gas or to give a series of different values of reduced flows. In a further embodiment, a circular section passage at the lower end of the housing receives a valve similar to the disc 16 while a second disc without apertures moves axially in relation to the end of the housing to serve as an on/off valve, the two discs being mounted on the same spindle with a spring tending to hold them apart. The valve may be used with the appliance described in Specification 1,357,141.

Abstract: 1437560 Accumulators for ropes and the like S H HUNKE 2 Dec 1974 [14 Dec 1973] 52099/74 Headings D1D and D1T In the rotary accumulator shown in Fig. 2 the rotor 12 carries spindles 3 that are offset from but parallel to the axle 14 of the rotor 12, there being a plurality of reels 4 on each spindle 3. A rope 1 passes from an entry guide wheel 5 over a first reel 4 of one stack, under a first reel 4 of the other stack and then away via an exit guide wheel 6. By rotating the rotor 12 and moving it axially so that it approaches the guide wheels 5, 6 the travelling rope 1 may be wound up on the stacks of reels 4. Subsequently, by reversing the rotation and traverse of the rotor 12 the stored quantity may be unwound. The invention is applicable to lines used in the processing of cable, wire, rope, string, tape or strip. When the tension in the line of material diminishes, the torque exerted by a drive motor 9 exceeds the resisting torque imposed by the line tension and the accumulator 10 is then rotated by the motor 9 in a direction winding up the slack in the material. The accumulated material is discharged when the torque developed by the line tension exceeds the torque of the motor 9.

Abstract: 1,133,215. Alumina. HALCON INTERNATIONAL Inc. 17 Dec., 1965 [18 Dec., 1964], No. 53639/65. Heading C1A. [Also in Division C2]  Activated aluminas, which are at least 99% by wt. pure and preferably have a surface area greater than 10 m<SP>2</SP>/g., are subjected to heat treatment and, optionally, doping to give improved catalyst supports. The heat treatment may be at 500-2000 C. for 1-100 hrs. Heating, and subsequent cooling, are preferably effected at a slow rate. Particular improvement in gamma-alumina is observed and is attributed to the formation of eta- and thetaalumina. The aluminas may be doped by the addition of 0À01-50 gram atoms of Sb, Ti, Sn or W, in the oxide form, per 100 moles. Impregnation with the dopand is accomplished by conventional methods, e.g. by treating the alumina with a solution of a decomposable salt of the metal. It is suggested that the alumina crystal is stabilized in the presence of the dopand. It is preferred to introduce the dopand before subjecting the alumina to the heat treatment. Examples 1, 3 and 4 describe the heat treatment of doping of various forms of alumina.
