Title: Thermoplastics tube drawn with oriented molecules - to improve quality and/or economise material by increased density
Inventor: WUERTZ FRITZ
IPC: B29C48/885
Filed: 1974-03-29
Abstract: A method of saving material and/or improving the quality when making plastics tubes operates by orienting the molecules of a polymeric, crystallisable thermoplastics in at least one of the three diemsions in number of stages; the plastics tube is extruded as a smooth tube and pre-oriented in a first stage, the tube being pre-drawn in at least one dimension; in a further stage, while the tube is being finally shaped, the molecules are further oriented in at least one dimension with further drawing, the drawing being regulated in each stage to a specific degree, all the separate orientations and drawings being adjusted to one another throughout the whole process until a specific total degree of orientation and drawing has been obtained. As compared with amorphous material of the same constitution, increases of density as follows are obtained: PVC, by 0.003-0.06 g/cm3; for polyolefin, polyacrylonitriles, polyamides and polyesters, by 0.01-0.06, generally exceeding 0.01 g/cm3, as measured at 23 degrees C according to the ASTM standard, by the "Pkynometer Method".

Title: Distillation of bituminous materials - after solution in inert halogenated liquids forming azeotropic mixts.
Inventor: FEHR KARL DR
IPC: C10C1/00
Filed: 1974-07-30
Abstract: Distillation of bituminous materials after soln. in a solvent which is structurally unchanged at the boiling range used, prevents polymerise., polycondensn., decomposn. and cracking of the bituminous material, and forms an azeotropic mixt. with the latter, so that the mixt. distils over at a lower temp. than its components and leaves a tough to rigid plastic material as distn. residue. The process is used for the treatment of distn. products of coal and petroleum, natural resins, asphaltities, asphalts, and their fractions and residues obtained by distn. or soln. The pitch and bitumen residue after distn. are free of mineral components, which are removed by centrifuging before distn., and also free from crystalline or oily high-boiling materials. They consist substantially of so-called 'free carbon and can be coked without further treatment to produce electrode coke. They can also be mixed in any ratio with tar products, e.g. road tar or pitch, and used for road building, rubber fillers or insulating materials, as protective coatings and for underwater construction.

Title: Synchronous clock pulse train generator - enables recovery of digital information signal from digital two-phase carrier signal
Inventor: WARNATSCH ROLF
IPC: H04L7/033
Filed: 1974-06-20
Abstract: The carrier signal is generated for data processing by a logic circuit linking the information signal with the clock pulse train. A needle pulse train derived from the two-phase carrier controls a three-stage counter, to which pulses from a pulse generator are applied; this counter third stage blocks the pulse generator, so that a pulse train present in a counting stage delivers the clock pulses after suitable shaping; needle pulses generated by differentiation of edges of the two phase carrier signal are applied to a first input of an AND gate, whose second input is controlled by a signal from the counter third stage; this gate resets the counter; the clock pulse generator frequency is tunable.

Title: Economical shower unit with heat exchanger - has cold water supply passing by hot waste water in counterflow thereby absorbing heat
Inventor: OHE WILFRIED VON DER
IPC: A47K3/28
Filed: 1975-01-22
Abstract: The shower unit comprises a shower head (1), water heater (3), and a heat exchanger (5) which is designed as the shower tray and is thus connected in to the waste water flow (8) on one side and the cold water supply (13) on the other.

Title: Equipment fixing point for armoured vehicles - has nut fitted behind holder plate which is welded to vehicle panel
Inventor: BOEHM GUENTER
IPC: F16B37/04
Filed: 1975-05-24
Abstract: The fixture for equipment in armoured vehicles consists of a U-shaped plate (1) which is welded by the plate ends to the panel (6) on the vehicle. Held under the plate is a square nut (7) so that the threaded hole is beneath a larger hole (9) in the holder plate. The angled sides of the plate have the end corners (10, 11) turned downwards to ensure that the nut (7) is unable to slide out from beneath the holder plate (1). The nut is held against the holder plate by means of a U-shaped spring (12) between it and the vehicle panel. Alternatively, the legs of the holder plate can be in S-formation to give the legs greater elasticity when pressure is put on the holder plate. This method produces a fixture which when welded in position provides a safe fixture whose nut cannot fall away from the holder or turn in the holder with the screw.
