Title: Process and apparatus for carrying out reactions
IPC: B01J19/00
Filed: 1940-08-28
Abstract: 543,538. Alkali metal hydroxides, hyposulphites, sulphides &c. EDWARDS, G. E., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Aug. 28, 1940, No. 13564. [Classes 1 (ii) and 1 (iii)] In processes wherein an alkali metal amalgam is reacted with a liquid by causing it to flow down a substantially vertical metal sheet immersed in the liquid, even distribution is obtained by siphoning the amalgam over the edge of the supply trough on to the sheet by a plurality of independent passages terminating at the same level on the sheet. The passages are preferably formed by arranging a number of parallel wires 7 over the edge 4 of the trough, extending to the same level on the surface of the sheet 6, the wires being held in place by a member 8. The spacing is such that the amalgam rises by capillary action in the spaces between the wires and between them and the surface of the trough and sheet. Specified reactions are the production of caustic alkali, of hyposulphites from sulphites, and of sulphides from hydrosulphides. Specification 543,539 is referred to.

Abstract: 954,921. I.C. engine construction; valves. J. J. ROSIER. April 14, 1961 [April 14, 1960], No. 13589/61. Heading F1B. An I.C. engine comprises a cylinder block 5, Fig. 1 and a surrounding reaction member 7 coupled together and mounted to rotate at the same speed and in the same direction around relatively offset stationary axes, at least four cylinder bores each housing a piston coupled a connecting rod 42, Fig. 2, to the reaction member, each bore centre line being in a separate plane perpendicular to the axes, the spacing between adjacent planes exceeding the radius of the bores and a valve member 14, coaxial with the block, and rotatable relatively to the block to control communication between the bores and inlet and exhaust passages in the valve member. The cyclinder block 5 and flywheel 7 consisting of end rings 30 connected by blades 11, are mounted for rotation in a stationary housing 23 and are coupled together by resilient pivotal links 6. Each cylinder has an inlet and an exhaust port co-operating with openings in the shaft 14 which comprises concentric tubes 15, 16, the interior of the inner tube 16 being divided by partition 17 into two inlet passages 33, each of which is connected at 34 to combustible gas supply means. The outside of tube 16 has raised parts 18, 36, 38, 39 which co-operate with the inside of tube 15 to define two exhaust passages each communicating at its outer end with spaces leading to the exhaust ducts 42. Shaft 14 is driven from the cylinder block in the same direction and at half the speed by a toothed nylon belt (not shown). The guide partitions 18 may be provided with oil grooves. Operation. Combustible gas mixture is fed through both passages 33, the openings in tubes 15, 16 and the ports in the block to the cylinders in which pistons 8 operate on the four-stroke cycle to impart motion to both block 5 and fly wheel 7 by means of links 6. Exhaust'gases are removed through the passage between the tubes 15 and 16. Cooling air is drawn into the housing at 21 and the centrifugal action of blades 11 causes air to flow past the cylinder cooling ribs through the gaps between blades 11 and outwardly through a discharge channel 22.

Abstract: 672,706. Ammunition cartridges. PARIS, C. May 23, 1949. No. 13733/49. Class 9 (i). [Also in Group V] A cartridge case for military ammunition with a body of plastic moulding material and a metal cap is assembled during the moulding of the body, means being provided for anchoring the plastic material to the cap. The body 1, Fig. 1, may be moulded from a polyamide derivative and the cap 3 may be knurled, serrated or roughened to hold the body. The cap has a flange 4 to facilitate extraction from the cartridge chamber of a firearm. The flange may be replaced by a groove and the anchoring means may be circular ribs on the cap to which the body may be moulded. The cap may be ribbed both internally and externally, Fig. 9, the external ribs corresponding to the internal grooves so that the thickness of the metal is uniform. Figs. 4 and 5 show a multi-part core used in moulding the body 1 on the cap 3. The core has a central stem 8 with a lower part of reduced diameter, bevelled edges of peripheral elements 9, 11 fitting into the recessed shoulder between the upper and lower part of the stem. The lower part 10 of the elements 9 is shaped to fit into a groove in the cap. After forming the case, the central stem 8 of the core is removed thus freeing the elements 9, 11. The elements 11 are free to move inwardly, whereupon the elements 9 can be removed. A modified core (not shown) has the peripheral elements 9 formed with a hook fitting into a seating at the -lower end of the stem. The number of the peripheral elements may be varied. The resultant case where it is connected to the cap may have internally a paraboloidal form. The case may have a projection 14 with a passageway 15 communicating with the detonator chamber 16, so that the propellent may be ignited centrally (Fig. 9). The projection 14 may be integral with the body 1 or with the cap 3.
