Title: Process for producing compounds of lead
IPC: C01G21/00
Filed: 1931-06-15
Abstract: Lead oxychloride precipitated from a brine by an alkali or alkaline-earth base is dechlorinated by contact with water and a base such as caustic soda.  The resulting lead hydrate or oxide may be roasted to form litharge or red lead or be dissolved in an acid such as nitric or acetic acid to form a soluble basic salt. From the latter the carbonate may be obtained by treatment with carbon dioxide, or the hydrate by treatment with ammonia.  The dechlorinated product, or the carbonate or hydrate, may be converted to other salts such as the chromate or sulphate. Specifications 365,964 and 370,738 are referred to.  The Specification as open to inspection under Sect. 91 (3) (a) of the Acts comprises also dechlorination by means of water only. This subject-matter does not appear in the Specification as accepted.

IPC: A01M23/20
Filed: 1955-06-16
Abstract: 778,830. Animal traps. BRONDEL, Y. G. June 16, 1955 [Dec. 3, 1954], No. 17433/55. Class 5(1). A trap for ensnaring animals in burrows comprises a cage having one open end and containing the mechanism illustrated in Fig. 2. The wire 1a defines the opening of the cage and hingedly supports a trap door 3 which is held in its open position by means of a catch 8 at one end of a rod 7 extending along the top of the cage, the catch engaging a hole in the trap door. The other end of the rod 7 is formed into a loop 9 through which is threaded one arm of a releasing device 10 hinged on the wire 16 of the cage. The releasing device, on being touched by an animal in the cage, is raised slightly and causes the rod 7 to rotate in the direction opposite to that indicated by the arrow f, whereupon the catch is disengaged from the trap door and the door drops to its closed position. When the trap is transported by means of the handle 12, the rod 7 and the releasing device 10 may be locked in position at the top of the cage by means of a spring 16 threaded on the rod and terminating at one end in a hooked lever 16b and at the other in a hook 16a. The locking is effected by rotating the spring on the rod until the lever 16b engages a hook 17 formed on the cage, and the hook 16a engages the catch 8. Bait may be placed in the burrow beyond the releasing device 10 as shown in Fig. 5, or a bait holder may be incorporated in the trap. Means in the form of a closed passageway inside the cage may be provided for ensuring that the animal backs on to the releasing device.

Abstract: 1,221,107. Gettering; ion pumps. THOMSON-CSF. 17 April, 1968 [21 April, 1967], No. 18244/68. Heading HID.  A vaporizer for getter pumps is made by providing a layer of chemically pure Ti 13 on a support 11 of a metal having a melting point higher than Ti, e.g. W, Mo or Ta. A wire 12 of Mo or W is wound on a W heating wire 11 and a layer 13 of chemically pure Ti is deposited thereon by pyrolisis of titanium iodide. Since the Ti is chemically pure it will not evolve gas in operation as compared with lower grade Ti which may contain argon or hydrocarbons introduced during furnacing or wire drawing operations. The vaporizer is mounted axially in a tubular envelope cooled by circulation of liquid nitrogen in a cooling spiral to form a getter pump incorporated in a system (Fig. 2, not shown) which also includes a primary suction pump and an ion pump.

Abstract: 1513254 Rotary positive-displacement fluidmachines ROVAC CORP 1 May 1975 [1 May 1974 17 March 1975] 18251/75 Heading F1F [Also in Division F3-4] A gas cooling unit comprises a combined sliding-vane compressor and expander, a heat exchanger between the compressor outlet and the expander inlet, and means for injecting an additive liquid in finely divided form into gas entering the compressor inlet. By evaporating in the compressor to lower compression temperatures and condensing in the expander to increase expansion temperatures the additive liquid is stated to improve the efficiency of the unit. The compressor and expander may be separate, or as shown, integral having vanes slidable radially in an oval-sectioned chamber 12. Gas flow through the heat exchanger 45 is cooled by air driven through ducts 83 by a fan. A nozzle 92 is supplied with water condensed in heat exchanger 45 or from a separate source, and the injected water may be atomized by an impellar or a Piezo-electric element driven by an oscillator. Cooled gas e.g. air from the expander may be mixed with fresh and/or recirculated air in a space 53 after passage through a porous sintered metal cylinder 60. Condensed water from heat exchanger 45 may be passed into air entering or leaving the expander to humidify the air. Water can be supplied to nozzle 92 only during unit start-up by a manually operable injection device Fig. 9 (not shown). In a modification, a second heat exchanger (50a), Fig. 8 (not shown) inter-connects the expander outlet and compressor inlet to form a closed circuit. The unit can be used in a vehicle for heating or cooling air using heat exchangers 45 or 53 respectively.
