Title: Continuous polyurethane foam block production - on trough conveyor formed from bottom and side foil strips
Inventor: OCHNER PAUL DR ING
IPC: B29C44/28
Filed: 1973-03-27
Abstract: Thick strips of plastics foam (soft polyurethane foam based on polyesters or polyethers) are produced by pouring the mixture with the reaction components into a conveyor consisting of a bottom strip and two side strips forming a trough in which the foam rises upwards. The PVC or polyethylene foils forming the side walls are split in the upper part of the foam block into offset strips by continuous or intermittent parallel horizontal cuts.

Title: Testing and calibrating instrument for information syst - has internal auto collimator and exchangeable external components
Inventor: BAUMGARTNER VIKTOR
IPC: G01B11/27
Filed: 1973-08-29
Abstract: The instrument for testing and calibrating optical information transmission installations has certain components e.g. the illumination source and observation assembly exchangeable according to the application. The main section comprises a tube which has at one end a collimator mirror held in a calotte and attached to the tube through ferro-nickel rods, which compensate for changes in temperature. The distance between the mirror and a prism with a filament cross in the central axis of the tube, therefore remains constant. The prism is held by an arm connecting through the side of the tube to the exchangeable components, the arm being arranged near to a glass disc sealing the tube at the opposite end to the mirror. Light from the source is split by a divider which directs it to the prism and the observation assembly.
Patent DE-2345814-A1 (DE)
Title: Copolymerising acrylic acid and styrene monomer - and short-stopping with solvent, giving coating, impregnating and rust-removing compsns.
Inventor: KAEMMERER KLAUS ALBERT UWE
IPC: C08F220/06
Filed: 1973-09-11
Abstract: Copolymers of acrylic acid and a styrene monomer are prepd. by copolymerisation in presence or absence of initiators and opt. of promoters, and short-stopping the polymerisation by addn. of a solvent at the point when there is an obvious increase in viscosity. Solns. of the copolymers are used as coating compsns., or as impregnants for soft woods, giving protection against weathering. The copolymers act as rust-removers if painted onto rusted iron or steel surfaces; removal of the coating leaves a clean metal surface. The cyclic ethers and alcohols used as solvents evaporate rapidly and the copolymer film hardens quickly at room temp. The copolymers are colourless and glass-clear. The compsns. adhere well to polar surfaces and convey water-repellency. The necessity for removing initiator residues is avoided, and the properties of the prod. are not affected by such residues.

Disc and mould can be equipped with servos acting in the direction of the disc axis, typically in the form of jacks. The external form of the pestle can be matched to the internal form of the mould and the disc can run on ball-bearings on the crank.

Title: Enamelled-metal-retort electric heating and radiation furnace - without antenna-effect deflection in open area of conductive ceramic layer
Inventor: MEYER HELGE
IPC: F24C15/00
Filed: 1973-12-19
Abstract: The enamelling extends outwards from the inside of the retort to beyond a peripheral surface area against which an electrically conductive sealing fits when the door is closed, this enamelled area being overlaid with a cohesive layer of electrically conductive ceramic material, linked to the retort through a gap in the enamel, with a short-circuit established for radiant energy from the retort, to check harmful radiation from the edge area of the ceramic layer which extends across the adjoining door sealing. In the area of the conductive ceramic layer which lies in the open, it is free from any radiation deflecting acting in antenna fashion. Electric connection between ceramic layer and retort may lie inside the space shielded by the door sealing.
