Filed: 1970-10-06
Abstract: 1284628 C-13 enriched CO 2  and carbon UNITED STATES ATOMIC ENERGY COMMISSION 6 Oct 1970 [22 Oct 1969] 47426/69 Heading C1A CO 2  is enriched in C-13 by reacting the CO 2  with a solution of isobutylamine in isopropanol to form a carbamate, and then decomposing the carbamate to form the enriched CO 2 . A catalyst, e.g. CuCl 2 , may be dissolved in the solution. The carbamate may be decomposed by heating to boiling, e.g. 65-70‹ C., under reflux, the condensate and CO 2 -free solution being recycled to react with further CO 2 . The process may be repeated in 4 further stages. C-13 enriched carbon may be produced by reducing the CO 2  to CO over Zn at 400‹ C., dissociating the CO with H 2  over Fe at 600‹ C., and purifying the carbon with HCl at 1100‹ C.

The softening temperature of the slag, above which liquid phases occur, is determined by taking samples from the mould. If a suitable powder has not been chosen, fluxing agents are added to correct the softening temperature. In the graph, in which the slag softening temperature is plotted as abscissa against the strand surface temperature as ordinate, the line 4 represents surface temperatures (150 limit) above which slag influence for more than two minutes may cause cracks. The surface temperature of the strand is measured at a number of points, e.g. pyrometrically, and the secondary cooling water regulated accordingly. Compositions of steel, powder and slag are given.

Abstract: 1356894 Obtaining aluminium from waste FOSECO INTERNATIONAL Ltd 20 Oct 1972 [22 Oct 1971] 48510/72 Heading C7D Particulate aluminium is obtained from aluminium-containing packing waste, by comminuting compressed bales of waste prior to heating at 600 to 660 C to carbonize any organic materials and separating the aluminium from the carbonized residue. The comminuting step is preferably effected by a hammer mill or blade grinder, and the comminuted material fed, preferably in flake form, through an inverted hopper to the heattreatment furnace, which may be a rotary tubular furnace. The operation of the furnace may be continuous and self-sustaining once enough heat has been supplied to initiate the calcining, cooling may be necessary to maintain the temperature below 660 C. The material after heat-treatment is hammer milled either before or after conveying to a cyclone separator where the carbonaceous material is removed. A sieving operation may be incorporated, oversize products being recycled; the product preferably has a particle size less than 0À15 mm, and may be used in aluminothermic applications.

The carrier as well as being a drum, can be in the form of a flat sheet, Fig. 6 (not shown) lying on the web, with the styli moving over the top of the sheet. The conductors, e.g. enamelled wires, may end just below the outer surface of the carrier such the corona electric discharge transfer is used. The web can be moved (Fig. 4), from opposite the styli to a position where it picks up developer particles 28, adhering to the drum as a result of the drum dipping into a bath of developer opposite the styli. In manufacturing the carrier may have holes bored through by laser beams and the holes filled with a conductive medium.

Title: Improved Brake Pressure Proportioning Valve
IPC: B60T11/34
Filed: 1967-11-07
Abstract: 1,160,108. Pressure-reducing valves. KELSEY-HAYES CO. 7 Nov., 1967 [18 Nov., 1966], No. 50669/67. Headings F2F and F2V. A pressure-reducing valve for insertion between a master cylinder and vehicle brake cylinders comprises a plunger having a valvehead spring-biased to an open position until fluid pressure acting over the cross-sectional area of the cylindrical portion of the plunger causes the valve to close, and an elastomeric seal surrounding the cylindrical portion and pressed against a shoulder associated with the plunger to exert a supplementary force on the plunger when the fluid pressure reaches a second predetermined level. In Fig. 2, the valve consists essentially of a plunger 56 urged by a spring 68 into a position where a shoulder 66 abuts the top of a blind hole 42 in the casing. Fluid from the master cylinder enters a thread opening 28, passes around a number of semispherical bosses 102 on an elastomeric member 98 and emerges through a threaded outlet 32 to the rear brake cylinders (not shown). When the pressure from the master cylinder reaches a predetermined level, the bottom of the plunger 56 will be raised against the spring 68 until a shoulder 62 abuts the elastomeric member 98 and closes the passage to fluid. Subsequent increase in master cylinder pressure act on the valve over an effective annular area (shown at 104) equal to the difference between the cylindrical portion 96 and the shoulder 62. The valve then opens slightly, bleeding fluid to the outlet at a lower pressure than that at the inlet. At a higher level of inlet pressure, a sleeve 88 is raised and presses a washer 90 upwards against a spring 94 so that the effective area of the valve is the difference between that shown at 105 and the shoulder 62. The outlet pressure therefore increases at a still lower rate. The braking pressure on the rear wheels is thus progressively reduced compared with that on the front wheels which are supplied directly from the master cylinder (Fig. 1, not shown). In a modification (Fig. 3, not shown) the sleeve 88 is formed integrally with the plunger and the elastomeric seal 80 of Fig. 2 is made less pliable so that it provides the necessary restoring force without the need of the spring 94.
