Abstract: 1,268,377. Cleaning metals etc.; electrolytically producing fluorine. J. E. LOVELOCK. June 16, 1969 [June 17, 1968], No.28811/68. Headings C7B and C7E. [Also in Division C1] Metals, semi-conductors, and glass are cleaned by gaseous fluorine or chlorine trifluoride in a chamber of e.g. copper, steel, iron, p.t.f.e. or fluoride glasses which is resistant to the fluorine and the escaping gas is passed through a trap containing activated carbon. The fluorine may be formed in situ e.g. by placing the article between concentric cylinders which are a porous nickel or carbon anode and a porous nickel cathode, the space between containing a potassium hydrogen fluoride electrolyte. The gas may be diluted with argon, nitrogen or air.

[Class 107] [See also Group II] Small-faced kneading tools, employed in the making of concrete roads, are provided with dome-like or elliptically-arched end faces. The tools b, Fig. 1, may be mounted on a machine behind a depositing and spreading device and in front of one or more rammers and may be rigidly or resiliently arranged on a poweractuated ram-plank a extending laterally of the machine. Alternatively, the tools may be mounted on a manually operated implement. In one construction, Fig. 5, the implement comprises a handle j connected to the ramplank a by a rod o. The ram-plank is of hollow construction and carries an electric motor m having two eccentric crank pins m<1>. The latter are connected by rods m<2> to a, plate m3 which is guided in the body of the ramplank and which carries the kneading tools. The latter are thus given a vertical vibrating movement which is superimposed on the stamping movement of the rod o. In another construction, vertical vibrations are imparted to the implement by the motion of a piston actuated by compressed air. In a modification, the separate tools b are replaced by a strip g of the cross-section shown in Fig. 3. Specification 363,004 is referred to.

Abstract: 1334810 Treating exhaust gases GENERAL MOTORS CORP 22 June 1972 [25 June 1971] 29317/72 Heading F1B I. C. engine exhaust gas purification system has a catalytic reactor in which the exhaust gases are caused to pass in succession through two chambers respectively containing catalysts for purifying the exhaust gases by reduction and by oxidation, said chambers being accommodated in a common hollow perforate body and being separated from each other by a perforate partition which has channels therein for the supply of air thereto. A casing 1 contains a hollow body 2 in which are the catalyst chambers 3 and 4, the chambers being separated by a partition 5 consisting of perforate metal sheets spaced apart by beads and shaped to form channels, which are connected to an air supply.

Class 17(2) [Also in Group VIII] A process for making shoe upper components comprises forming a multi-ply construction by injecting a plastic solution between a pair of outer layers of shoe material between which is a layer of foraminous material. In making the counter shown, a layer of foraminous material, preferably a plastic screen such as of vinylidene chloride, is placed between the upper material and the lining, either of which may be of leather or of woven material, and the layers are sewn together at 18 round the edges to form a pocket. A quantity of plastic material such as cellulose nitrate solution is then injected into the pocket by an airgun 20 having a needle-like nozzle 21 and the component is pressed between calendering rolls to distribute the plastic evenly and to adhere the layers. The stiffening produced can be varied by employing different foraminous material or plastic solution. The process can be used on various shoe upper parts, such as the quarter, box toe, ankle straps, or for stuffing bows.

Filed: 1926-11-23
Abstract: 280,366. Chamberlain & Hookham, Ltd., and James, S. Nov. 23, 1926. Motor meters. - A meter which is adapted to run continuously in order to minimize frictional errors is connected by epicyclic or other gearing with a constant-speed motor so that no load no motion is transmitted to the counting-train. The worm a on the meter shaft drives, through wheels b, c, one of a pair of sun pinions d, e, the other of which is driven through wheels f, g from a worm h on the shaft of a small constant-speed motor, clock, &c., the arrangement being such that at no load the sun pinions d, e are driven at the same speed in opposite directions and consequently do not drive the counting-gear shaft j which carries the planet pinion i. The counting-gear k is therefore only affected when current is being taken in the consumer's circuit. To avoid errors due to variations in voltage or frequency an electric constant-speed motor having the same characteristic as the meter is preferably employed. Specification 11825/13 is referred to.
