Title: Tray column for stripping ammonia from solns. - having inter-tray cooling for ore separation processes
IPC: C22B3/02
Filed: 1975-09-10
Abstract: Column for stripping annonia from annonacal solns. or suspensions has a feed of the soln. in at the top and steam in at the base. It is divided into several zones by means of a series of trays mounted one above the other having normal liquid downcomers from tray to tray. IT is cooled in several stages down the column bypassing a coolant through the trays. The trays or pertitions can be double skinned with a passage for coolant through them. They can be conical shaped with run offs. Vapour lines can be provided to allow transfer of vapour from the vapour space of one stage to a subsequent stage. Method for stripping NH3 out of solns. and suspensions derived from the NH3 treatment of certain metal ores for metal recovery e.g. Ni, Zn, Cu, and Co. Soluble complexes are leached out of the ores and the metal is recovered as oxide or carbonate by stripping out the NH3 which is recovered. In conventional tray columns deposits of these oxides and carbonates level to form on the trays on the better surfaces. Cooling the trays avoids this.

Title: Reciprocating mechanism with a directly coupled electric motor - involving use of polyamide thrust bearings
Inventor: HONIG UWE
IPC: H02K7/06
Filed: 1976-04-16

Title: Machine for transforming unidirectional force into rotation - utilises magnetic, gravitational and centrifugal forces with interchange of air between cylinders to maintain motion
Inventor: GUERENNEUR PIERRE JEAN THEOPHI
IPC: F03G7/10
Filed: 1976-11-16
Abstract: A machine for transforming uni-directional forces into rotation consists of four circular plates held apart by columns. A swashplate is connected by rods and levers to piston rods and pistons. The machine utilises the energy of a magnet, the gravitational force due to a mass mounted on a transverse beam and the centrifugal force due to a second mass also mounted on the beam. The motion is maintained by the continuous interchange of air between cylinders through connecting pipes. The power take-off is from a pulley driven by the swashplate.
Patent FR-2332954-A1 (FR)
IPC: B01D53/14
Filed: 1976-11-26
Abstract: Trace impurities in the form of oxygen, water vapour and nitrogen are removed from noble gases. Oxygen and water vapour are removed by chemisorption on the active metallic component of a composition which consists of a heat-resistant oxidic support having a large surface area and the metallic component contained on the support as a surface compound. Then the residual noble gas, in order to remove the nitrogen, is put into contact with titanium or barium (7) heated to from 400 to 800 DEG C. The appliance for implementing the method has a container (3) which holds the chemisorption composition and has a gas inlet (3a) and gas outlet port (3b). The gas outlet port (3b) is connected to the gas inlet port (5a) of an electrically heatable tubular furnace (5). The tubular furnace (5) is packed with titanium or with packings coated with barium.

Title: Roller for textile fabrics - may expand or lengthen to modify its volume to accommodate fabric irregularities
IPC: B65H23/02
Filed: 1976-11-25
Abstract: The roller is provided at each end with a casing which may be displaced by an endless screw. The casing moves over ramps, sliding on solid elements of the roller shaft, to spread diametrically the slats which constitute the periphery of the roller. Further, the slats may be displaced lengthwise by pivto rings at the ends of the roller, which are controlled by screw jacks or electro-magnets. The slats are joined to the rings by swivel joints. The roller adjustment may be effected precisely and automatically during the processing of the fabric sheets, by the action of screw jacks, or electro-magnets and/or cog wheels, to permit all kinds of volume change in the roller. It is possible that one selvedge may be wound on faster than the other, which can be detected by a scanning device, such as a photo-electric cell. By adjusting the diameter of the roller on one side, the fault may be corrected, Also, the over-running of selvedges, producing a lateral displacement of the cloth, may be corrected by the lengthwise adjustment of the peripheral slats.
