Title: Improvements in or relating to the deoxidation and degasification of copper and alloys thereof
IPC: C22B15/00
Filed: 1968-11-19
Abstract: 1,204,565. Refining copper and its alloys. L'AIR LIQUIDE SOC. ANON POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE. Nov.19, 1968 [Nov. 20, 1967], No.54938/68. Heading C7D. Copper or copper alloys are deonidized and degasified by introducing a reducing gas followed by an inert gas in finely divided form into the molten metal. Alternatively the reducing gas may be followed by a mixture of reducing gas and inert gas or the two gases may be added simultaneously throughout the treatment. In the apparatus shown the melt is fed to container 2 which has previously been flushed with inert or reducing gas and is treated with gas introduced through porous plugs 6, 8, exhaust gas escaping from the container via the orifice in lid 22 around stopper 12. The treated metal is run into hopper 4 by raising stopper 12, the hopper having previously been filled with nitrogen from inlet 36. Finally the metal is run into ingot mould 38 while protected by nitrogen introduced into gas bon 42 from inlet 44. The operation may be performed with continuous metal flow, a continuous casting installation replacing the mould 38.

Abstract: 1,122,190. Telescopic suspension struts. CATERPILLAR TRACTOR CO. 29 Dec., 1965 [3 Feb., 1965], No. 55042/65. Heading F2S. In a telescopic suspension strut comprising a piston 13 with damping orifices 26 and a valvecontrolled opening 28, and a two-part cylinder 11 with a honed cylinder liner 18, a seal, consisting of rubber-like rings 30, is held in a retainer 20 about midway between the ends of the cylinder 11 to encircle the piston in sliding contact therewith in an area that does not extend beyond the piston-rod end of the cylinder during normal telescoping movement.

Title: Pulse-Supervised Elevator System
IPC: B66B5/02
Filed: 1967-12-06
Abstract: 1,196,981. Lift control systems. WESTING- HOUSE ELECTRIC CORP. 6 Dec., 1967 [30 Dec., 1966], No. 55394/67. Heading B8L. Call memories BK11 are scanned sequentially by a pulse-operated scanner BK13 (typically at 1000 pulses per second) and when coincidence is detected between a call signal and a car position signal from BK9 the car is caused to stop. Scanning may be always in the same direction or alternatively in a direction corresponding to that of the travel of the car. For high-speed lifts the car or call signals are delayed for the time required for the scanner to interrogate one or more floors; this initiates stopping one or more floors ahead of the destination floor. To economize on signal circuit wiring these circuits operate on square pulses generated from an A.C. supply, distinction being made between pulses generated by positive half-cycles and those by negative half-cycles, and for reliability these pulses are interrogated during a " reference notch," i.e. a short period adjacent the peaks of the A.C. supply (Fig. 4, not shown). The complete control system is fully described, and uses logic elements such as NOT, OR, NOR gates and bi-stable memory devices. It provides for door opening when the car reaches a levelling zone, the door being held open for a predetermined " non-interference " time. An 80% loaded car will ignore landing calls and there is provision for " hospital emergency " despatch to a desired floor and for manual operation. If the scanner fails to locate a call within a prescribed time, or if the selector gets out of step with the car, the car automatically travels to a terminal floor, stopping at every landing. In multi-car systems a landing call is normally assigned to a car which has a car call for that landing, unless the car is fully loaded or is a substantial distance away. In addition, a reversible counter determines whether calls for landings between two cars travelling in the same direction are in excess of those ahead of the leading car; if they are, the leading car will stop for a call previously assigned to the second car under the arrangement above. Conversely, if there are more calls ahead than between, the lead car is made to by-pass a landing call which it otherwise would answer; this is to avoid " bunching " of cars. Any floor may receive preferential treatment by " weighting " it, i.e. associating more than one pulse with it.

Such materials are obtained by extrusion granulating a composition of a mixture of 10- 50 parts by weight of a liquid coagulant with 100 parts by weight of a vinyl chloride resin powder of particle size not greater than 10 microns, the liquid coagulant being water, a C 1  to C 8  alcohol, an aqueous dispersion of vinyl chloride resin particles, or a plasticizer for vinyl chloride resins. When the coagulant is an aqueous dispersion of vinyl chloride resin particles, the amount of liquid coagulant is regarded as being the amount of water in the said aqueous dispersion, based on the total weight of vinyl chloride resin in the raw batch (i.e. including that in the dispersion) taken as 100 parts.

The aluminium trichloride is formed as a gas which leaves the top of the reactor whence it is cooled and desublimation produces the aluminium trichloride as a fine powder. The gas distributer may be a conical funnel shape, either concave upward or concave downward and the reaction is carried out at a temperature of 310‹ .to 580‹ C.
