Patent DE-2108855-A1 (DE)
Title: Canister for atomic wastes
IPC: G21F5/00
Filed: 1971-02-25
Abstract: Transport canister for dry radioactive heat producing nuclear reactor wastes has a radiation shield of steel rings, which are chevron shaped in cross section. The canister is fitted with a base to enable it to be laid on its side. The radioactive waste is contained in a thin inner casing with ribs spacing it from the rings. Outside the rings is a similar space. The outside of the outer casing is covered with cooling fins. The bottom of the canister is a steel plate shaped to fit the groove in the rings. A reservoir for coolant, e.g. water, forms a spine along the top side of the casing, and has a safety valve. The cooling fins are encased in a hardwood outer cover. Cooling water picks up heat from the radioactive waste, flows up and out through zig-zag slots at the top of the rings. It flows down through the outer casing, giving up heat to the cooling fins and into the inner casing through similar slots at the bottom of the rings. Cooling air flows, also by convection, over the fins in counterflow to the cooling fluid.

Title: Transfer material conferring differential matting
IPC: B44C1/17
Filed: 1971-03-03
Abstract: Three-dimensional pattern effect (wood graining, marble, leather etc.), is obtained on a variety of surfaces (metal, plastic, paper, textiles) by a transfer system, which apart from the colour confers a differential matting effect on the surface. The transfer consists of a carrier (paper, polyethylene, etc.) which is firstly coated with a matted layer (nitrocellulose, ethyl cellulose, etc.), which can be attacked by special solvents, this layer in turn is coated with the transfer layer (chlorinated rubber, aromatic rubber cpds., etc.), which can be swelled by the solvent and permits it to penetrate to the matted layer, this transfer layer is coated with the image forming layer, and this layer is coated with an adhesion coloured layer, the last layer forming the bond with the surface to be coated with the transfer. Choice of solvent and resins determines the effect obtained. Transfer is effected by heat or pressure. The special solvents are ethyl or butyl acetate, cyclohexanone, MEL etc.

Title: Feeding or filtering rotor - with forced expulsion of contents from compartments by pressurised fluid
Inventor: WEHNER ALBERT
IPC: B65G53/46
Filed: 1971-11-25
Abstract: An apparatus for introducing a dry, moist or liquid substance into a pipeline or other vessel or for separating from liquid or gaseous mixtures comprises a rotor sub-divided into chambers and having both its ends closed so that access to these chambers is around the circumference. The rotor is rotationally mounted in a fitting housing with top inlet and bottom discharge, while a hollow, non-rotating shaft fixed to the housing is used to introduced a pressurised fluid; an arrangement of apertures around the lower periphery of this shaft within the housing causes the pressurised fluid to be introduced only into that chamber or those chambers which are in the lower position, thus causing forced expulsion of the material contained in these chambers into the further pipe-line or vessel. Pref. each of the compartments has a flexible membrane bottom and the rotor is used for filtering; as it revolves, the introduction of pressurised fluid causes these membranes to expel the contents of the compartments through the filter. Parts of the apparatus in contact with the contents may be of wear-resistant or flexible plastics, esp. polyurethane-based.

Title: Hydraulically regulated nozzle for an injection moulding machine - opening and closing precisely, held closed mechanically during changeover
Inventor: HEHL KARL
IPC: B29C45/23
Filed: 1974-02-28
Abstract: The needle valve stem of a nozzle for a plastic injection moulder, is operated, opening and closing the outlet to the mould, by a toothed lever pivoting in a recess of the nozzle body, and meshing with a rack on the valve stem. Lever is moved by the rod of a hydraulic piston. This is fed in common with the piston of the hydraulic device for injecting the plastic material into the mould, from the same pressure source. The forward sides of both cylinders are thus loaded together and the nozzle opens when pressure has built up in the injection line. Similarly, the annulus side of the hydraulic piston is fed in common with the pressure side of the hydraulic circuit for the motor turning the plasticising screw. When the spool on the control valve connects pressure feed to line the nozzle is closed and the screw rotates. A spring presses on the piston and keeps the nozzle closed. Simple and cheap design. Nozzle opens and closes with precise timing. Can if necessary be converted from a hydraulic to a spring-loaded mechanical operation.
