Patent DE-2335397-A1 (DE)
Title: Laminated gymnastic safety mat - non slip upper surface and intermediate shock damping panel
Inventor: ZELLEKENS ALBERT
IPC: A63C19/04
Filed: 1973-07-12
Abstract: The mat is intended to provide greater safety and shock absorbing capacity without greatly increased bulk. The underside consists of a strong woven material which is glued to a thick layer of foam rubber. A panel of compressed coconut fibre is bonded to the upper surface of the foam and is itself covered by a non-slip outer surface covering. The surface is designed to resist slipping in any straight line but allows the athlete's foot to turn. The fibre panel has a low elasticity in a direction parallel to the surface but a greater elasticity in a transverse vertical direction. Several mats can be linked together. The abutting edges are champered at an angle of appr. 35 deg. to form close joints.

Title: Prefabricated stacked pile with enlarged pile shoe - anchored by injection of setting compound through pipes in pile into clearance
Inventor: MAYER OTTO
IPC: E02D5/52
Filed: 1973-07-18
Abstract: The prefabricated reinforced concrete pile is driven into the ground and its lower enlarged end shoe forms a clearance between the surrounding soil and the pipe. The head of the pile has inlet openings for the hardening compound and the pile has channels for injecting the compound into the void between the pile and the soil. The length of the pile is extended by stacking a number of identical piles vertically on top of each other. The joints are supported by enclosing shells which also have channels for guiding the liquid compound so that it passes through the whole length of the stacked pile. The composite pile is enclosed over its whole length by the hardening compound. The driving process is continuous and a number of readily transported prefabricated concrete piles are joined readily.

Title: Electro-magnetic fluid pressure regulating valve - ball as magnetic armature and as sealing member
Inventor: KOCH ARWED V DIPL ING
IPC: F16K31/06
Filed: 1973-07-26
Abstract: The valve has a spool supporting a winding and enclosing a magnetic core in the form of a flanged hollow cylinder. The spool fits in the body with the base forming the yoke for the magnetic circuit. The seating member is a ferromagnetic ball which fits in a tapered cone formed in the yoke and rests on a sharp edged seat of non-magnetic material. When the coil is magnetised, the ball is pushed towards its seat until it balances the incoming fluid pressure. The shape of the yoke and seat provides a flat curve of the lift to magnetising force relationship giving better flow control.

Title: Valve cartridge for hydraulic props in mines - has slow acting and fast acting pressure release valves
Inventor: SCHMIEDEL SIEGFRIED
IPC: E21D15/46
Filed: 1974-03-13
Abstract: Valve cartridge for hydraulic props in mines especially for a yielding valve which is in service subject to pressure of fluid in pressurized enclosure of the props. The valve cartridge incorporates one or more drilled passages through which the fluid from the pressurized enclosure of the prop passes from its inlet side adjoining the pressurized enclosure to its outlet side positioned away from the pressurized enclosure. The outlet side of the valve cartridge is a cylinder locating a movable piston and its pressurized surface is smaller than the pressurized surface of inlet side of the cartridge. The pressurized fluid is throttled during its passage from the inlet to the outlet side and the piston which is spring loaded forms a pressure release valve which passes through only a small volume of the pressurized fluid when the pressure in the prop enclosure is slowly rising. When the pressure in the enclosure is rising rapidly the pressurized fluid is discharge through additional pressure release valve with a large discharge opening.

Title: Gaseous radioactive fission prod detector - contg scintillation gamma radiation detector or counter tube
Inventor: TSU DAVID DIPL ING
IPC: G01T7/02
Filed: 1974-04-06
Abstract: A device for detecting gaseous radioactive fission products comprises a scintillation gamma radiation detector or counter tube; the radiation detector is surrounded by a device which selectively delays the fission products entrained in a gas flow. Pref. this device comprises a helical tube wound around the detector and containing activated charcoal. Used esp. for detecting a burst in a fuel can or cladding in a nuclear reactor, by sampling of the gas atmosphere, e.g. the protective gas atmosphere above a liquid coolant, during reactor operation. The fission prods. emitting the radiation become concentrated in the vicinity of the radiation detector, thus reducing the obscuring effect of background radiation and permitting rapid detection of a burst can. A typical standard aimed at is the detection of a leak of area 0.2mm2 within 1 1/2 minutes.

Title: Fully automatic screen washing unit - removes residual ink from screen printing template frame
Inventor: MULLER GEORGE
IPC: B41F35/00
Filed: 1974-04-09
Abstract: The screen is moistened with solvent and has residual ink removed from it by means of brushes which rotate on both sides of the screen frame. The screen printing template frame is conveyed using transport rollers and moves slowly to the solvent spraying installation onto the guide rollers and finally passes the rotating brushes. Dusters or sponges can be used in place of brushes while the cleaning mechanism is powered mechanically or hydraulically. The amount of solvent necessary for a thorough cleaning operation is kept within modest bounds while the total time taken amounts to only a few minutes and requires no manual engagement.

Title: Reception circuit for isochronously binary modulated signal - makes use of clock pulse generator, counter and logic circuit
Inventor: PREY GERHARD
IPC: H04L5/22
Filed: 1974-07-24
Abstract: The clock pulse frequency is n times the modulation frequency, and the counter is controlled synchronously with clock pulses and by the logic circuit, so that if it deviates fron the nominal position it is either not affected at all, or is moved forward by one or two steps; in case of synchronism it delivers a taking over pulse at the middle of a bit. In order to avoid evaluation errors due to transmission erros (e.g. isochronous distortions), resulting in signal amplitude change during a scanning interval directly preceding the taking over pulse, repetition of the taking over pulse owing to the retention of the counting position (e.g. 011) and to the necessary phase correction between a specified reference counting state (111) and a signal amplitude change is prevented; a separate storage element, e.g. a flip-flop, is provided.
Patent DE-2437482-A1 (DE)
Title: Filament tensile force measuring device - has deflecting pins with air supported runner sleeves of very small mass for rapid response
Inventor: BUEB MICHAEL DR
IPC: G01L5/04
