Title: Electromagnetic wave polarisation changer - is by rotating the plane of polarisation of the waves
IPC: H01Q15/22
Filed: 1973-06-15
Abstract: Two or more metallic reflecting surfaces, fixed or movable are arranged so that the emergent ray is parallel or antiparallel to the incident ray. Plane polarised light is in general converted to elliptically polarised on reflection, but if the wavelength lies between the millimetre range and the visible range, the ellipse is narrow. A second reflection at suitable angle of incidence is used to cancel out the phase changes produced at the first reflection, and the final result is a change in the position of the plane of polarisation. The actual angles of incidence are to be calculated from the optical properties of the metal at the wavelength used. It is also possible to use this principle to change the position of the axis of the ellipse in the case of elliptically polarised light.

Title: Contact copper-plating of steel surfaces - using sulphuric acid, copper sulphate and a surface active agent
IPC: C23C18/38
Filed: 1973-10-16
Abstract: In a process for the contact copper-plating of steel surfaces by treating with a soln. of sulphuric acid, copper sulphate and a surface active substance, as the surface active substance there is used a quaternary salt of pyridine and a hydrohalic acid, this being used in the amount required to give uniform deposition of the copper on the surface to be treated. The pref. surface active agent is 2,4-di(methyl-N-pyridine)-methylenesaligenin dichloride (I). The surface active agent is pref. used in an amount of 0.02-3 g/l. In a pref. procedure, the steel surface to be treated is firstly dipped in a solution of the surface active substance and then dipped into a solution contg. sulphuric acid and copper sulphate. The copper plating gives increased electrical conductivity and increased corrosion resistance. The surface active agent retards oxidation and reduction processes on the steel surface, thus enabling corrosion-resistant and strongly adhering copper plating to be applied in a simple manner.

Title: Lost wax precision casting of precious metals - where exothermic mould is at a higher temp. than the molten metal
IPC: A61C13/00
Filed: 1974-03-11
Abstract: Precision castings are obtd. using a mould consisting, at least in part, of an exothermic mixt. which is ignited before the metal is poured into the mould so that the latter acts as a crucible, remelting the metal and prolonging its liq. state so that it completely fills all the intricate cavities of the mould. The exothermic mixt. after ignition pref. attains a temp. 100 degrees C. above that of the melt for 10-15 minutes and the cooling of the melt is pref. retarded by using an insulant round the mould. The device pref. uses the lost-wax process and a vacuum pump to apply suction to the mould cavity. Castings are esp. dental prostheses made e.g. using precious metals. The size of feeder head required is reduced which is important as the precious metals lose their desirable properties when repeatedly remelted.

Title: Evaporation of a liquid contained in a vessel - by blowing a swirling jet of hot gas onto solution surface
Inventor: BERGEY CLAUDE
IPC: B01D1/14
Filed: 1975-01-23
Abstract: Liq. is evaporated in a vessel by blowing a jet of hot air that is made to flow in spiral fashion onto the surface of the liq. so that the liq. is also driven in rotation. The gas is heated in an electric heater then conveyed to the vessel where it is directed onto the surface of the liq. by a nozzle at the end of which is a distributor. This distributor can be a hollowed cylinder divided into two by an augered diametrical wall or a flange that has three nozzles angled in the same direction. The evapn. can be stopped automatically by having a thermocouple dipping into the liq., the tip of which is a set distance from the base of the vessel, so that when the liq. level drops below the thermocouple tip, the measured temp. rises tripping a cut-out switch that closes the valve on the hot gas inlet. Used for evapn. of liqs. from a soln., e.g. a solvent from a soln. with dissolved products esp. solns. with radioactive products. Allows a high rate of evapn. without carry-over of any soln. or product. Uses less energy than conventional processes.
