Patent DE-4105014-A1 (DE)
Title: Vapour deposition - has closed tunnels of magnetic field lines over molten material in crucible with electron beam guns for ionisation
Inventor: FEUERSTEIN ALBERT DR
IPC: C23C14/32
Filed: 1991-02-19
Abstract: To apply an ion cladding to substrates or produce a reactive vaporisation of materials with a crucible and a magnetic field to ionise the vaporised material, the crucible walls form a pole shoe with the same polarity. A futher pole shoe is arranged in the crucible with opposing polarity, so that a closed tunnel of magnetic field lines can be set at the surface of the molten bath in the crucible. At least one linear vaporisation source is formed by a single electron beam gun or a group of guns to transmit electron beams at the surface of the molten material, to form a rectangle with side parallel to the crucible walls. A plasma is ignited within the closed tunnel of magnetic field lines, and the low magnetic electrons reflected from the plasmas are directed on cycloid paths. These electrons give a multiple ionisation of the vaporised material from the linear sources with a high deg. of ionisation. The crucible is pref. box shaped, with an open upper side in the vaporising direction. The crucible and its contents, are insulated electrically. The plasma can be intensified magnetically through a negative voltage potential at the crucible and its contents, and the plasma can also be intensified by the feed of an inert or reactive gas. The electron beam guns have conventional deflectors to give a band of electron beams. The electron guns are above the molten surface and outside a projected surface perpendicular over the crucible. USE/ADVANTAGE - The system is used in assemblies such as for vapour deposition of strip materials. The operation is a single stage action, to give a quality deposited layer on the substrate

Title: Contaminated metal recycling - uses decontamination furnace with exhaust gas heating to decompose toxic matter
Inventor: FISCHER REINHARD DR
IPC: F23G5/00
Filed: 1992-01-22
Abstract: The components contg. the contaminated metal are cold cut and placed in a hermetically sealed cabin, to be decontaminated at high temp. in a furnace using oxygen burners. After exhaust gases have been taken from the decontaminating furnace, they are heated to a temp. which decomposes the toxic matter. The gas is then cooled in a heat exchanger and passed through a gas cleaning assembly. Pref. the temp., in the decontamination furnace is set at a min. 800 deg.C but below the m.pt. of the contaminated metal. A temp. of over 1200 deg.C is used to decompose toxic organic matter in a chamber with oxygen burners to take the exhaust gas from the furnace. The exhaust gas is raised to the required decomposing temp. at one or more furnaces used to melt the scrap at the same time. Hot gas from the chamber or the subsequent smelting furnaces is used for direct or indirect heating of the decontamination furnace. The fuel for the oxygen burners contains more than 50% O2 and instead of conventional fuels such as oil or gas or coal together with oxygen, plastics waste or waste oil or other combustible waste organic matter can be used singly or in combinations. For cold breakdown, a remote controlled water jet cutter is used pref. with a grinding additive. A tunnel furnace with direct or indirect heating is used for decontamination and an electro-furnace can be used. USE/ADVANTAGE - The technique is used for example, to recover the copper from oil-filled transformers contg. PCB, without allowing polychlorinated biphenyls escaping into the atmos., to give copper scrap within the permitted max. 10 ppm. of PCB

Title: Optical rangefinder with electronic correction for spot eccentricity - evaluates measurement error due to e.g. inclination of object surface in terms of spot displacement at second photodetector.
Inventor: MAAG ROBERT
IPC: G01B11/02
Filed: 1992-04-09
Abstract: The beam from e.g. a collimated laser diode (1) passes through crossed cylinder lenses which focus the rays in both sectional planes and adapt the dia. of the beam to the numerical aperture of an objective lens. A mirror section cuts off half of the incident beam and deflects light scattered from the object to a differential photodiode detector. A beamsplitter reflects part of the deflected beam on to a four-quadrant photodetector in an orthogonal plane. A first electronic circuit (11) produces a signal corresponding to the position of the light spot on the detector. A second circuit (21) produces a monitoring or correction signal derived from the eccentricity of the spot position. ADVANTAGE - Correction of inclination of or scattering object surface. Is effective for additional types of coaxial rangefinders and esp. those operating on Foucault section principle.

Title: Edible coating - is a three component mixt. to make food containers impermeable to fluid
Inventor: DOLDERER ERICH A
IPC: B65D65/46
Filed: 1992-06-30
Abstract: The edible coating for coating a baked mass, and make it impermeable to fluid, is composed of three components suitable for human consumption. Pref. the first component is a vegetable wax of carnauba or candellila, the second component is ethyl cellulose and the third is an edible oil as a softener using rhizine oil which loses its laxative properties when heated to 160 deg. Suitable aromatics can be mixed in with the three components. The ethyl cellulose is mixed while the components are at room temp., and the molten wax is stirred in. All three components are heated to 170 deg.C for the ethyl cellulose to dissolve completely. The temp. of 170 deg. may not be exceeded by more than 10 deg.C. to prevent oxidation and darkening the coating. The dissolving action is shrouded from the air by an inert atmosphere. The hardened mass, after cooling, is liquefied by local melting without darkening through oxidation. The coating is applied to the baked carrier mass while it is still warm, in an airless application immediately after it has been shaped, while the coating is at 170 deg.C for uneven flow of fine droplets to form an impermeable layer. USE/ADVANTAGE - For ice cream tubs as drinking cups, or for plates and dishes for hot sausages, etc. The coating prevents softening through liq. is suitable for human consumption, and any waste can be used for animal fodder.
