Title: Casting plastic articles with a decorative pattern by
Inventor: GEORGES QUADENS JEAN ACHILLE
IPC: B29D7/01
Filed: 1969-03-24
Abstract: In the manufacture of cast plastic articles, such as decorative plates, a plastic material is cast onto a rigid support which is covered by a thin sheet of a plastic material such as polyethylene. The deformation of this sheet during the polymerisation of the cast plastic creates in the body of the cast plastic striations which are irregular in direction, in pattern and in depth. After polymerisation is complete, the thin sheet is separated from the cast body. According to the present proces, one places between the rigid support and the th in sheet, bodies which form a relief on the surface of the cast plastic, thus increasing the decorative effect.
Patent DE-1923723-A1 (DE)
Title: Ion exchanger
Inventor: ZAZA GIORGIO
IPC: B01J49/90
Filed: 1969-05-09
Abstract: The exchange resin bed in a column has a layer of easily compressible buffer material, such as polyethylene, above it to retain the resin in place. Such an arrangement however leads to unnecessary loss of regenerant liquid in the space occupied by the buffer. This loss is avoided by provision of a suitable distributor located in the buffer material just above the ion exchange resin. During backwashing, the buffer material is lifted from the resin bed into the expansion space. It can be arranged for the buffer material to be discharged from the column during backwash, and the returned for normal operation.

Patent DE-2007319-A1 (DE)
Title: Thermostatic mixer for hot and cold liquids
Inventor: HALKEMA MAARTEN
IPC: G05D23/13
Filed: 1970-02-18
Abstract: The mixer has a distributor which reacts on the deformation of a thermostatic bi-metal strip contacting the mixture, and which controls the output from two nozzles thus setting the pressure in the back pressure chambers. The chambers are closed by the actuation membranes of each of the two distributor valves, thus regulating the input of the cold and hot water, respectively. The chambers are fed into the off take above the valves. Each back-pressure membrane is fed by means of a input-tube arrangement, which has an expanding cross-section corresponding to the aperture of the valve, so that the distributor apparatus is able to control the output of the two output nozzles. At the same time the pressure in the two back-pressure chambers is altered, and the output is controlled by the distributor valves. The arrangement is for use with sanitary apparatus.

Patent DE-2155243-A1 (DE)
Title: Reactor fuel element internal seal - inhibiting hydrogen escape
Inventor: GREGORIUS KLAUS DIPL ING
IPC: G21C3/20
Filed: 1971-11-06
Abstract: A reactor fuel element in which the fuel is an intimate mixture of fissile material and zirconium hydride and in which the interspace between the fuel and end cap is sealed by a composite plug. The plug comprises an inner cylinder of zirconium hydride shrouded by a cup which is enamelled on its inner and outer faces. A glass seal is interposed between the outer enamelled face of the cup and inner enamelled face of the fuel element cladding. On assembly the element is clamped and heated to induce a hydrogen release from the zirconium hydride and create a partial pressure in the interspace which combined with the differential expansion of the plug and cladding compresses the molten glass to form a seal. The seal remains effective on cooling and acts to inhibit the escape of the hydrogen moderating constituent in the fuel in the event of damage to the end cap.

Title: Force measuring scales for weight determination - is of people or foodstuffs and includes digital signal generation
Inventor: GUNTERSDORFER MAX DR RER NAT
IPC: G01G3/16
Filed: 1973-08-13
Abstract: The force to be measured acts on a mechanical spring element and changes its mechanical stress. A piezo-electrical transducer is connected directly or via transmission elements to a spring element, thus the spring-element produces mechanical resonant vibrations. The trasducer is automatically supplied with AC voltage. The variable frequency of the AC voltage corresponds to the mechanical resonant frequency of the spring element, dependent on the mechanical stress of the spring element. A frequency meter measures the resonant frequency. The spring element could consist of a string and at least one end is connected to the transducer.

Title: Quick release arrangement for piercing mill mandrels - with radially movable locking elements operated by moving bolt in mandrel rod
Inventor: HAEUSLER KARL-HEINZ
IPC: B21B25/06
Filed: 1973-09-17
Abstract: In a quick-release mechanism for the connection between a mandrel and a mandrel rod in a rotary piercing mill, the mandrel has a central blind bore with an annular groove for seating radially moveable locking elements provided in side openings in the end of the hollow mandrel rod. The elements are moved by a cylindrical locking bolt which runs inside the mandrel rod or inside an attachment to the mandrel rod. The locking bolt is shorter than the distance between the annular groove and the base of the mandrel bore and is connected via a tapering run-out section to a locking bolt rod inside the mandrel rod. This locking bolt rod has a radius which is smaller than the locking bolt radius by about the seating depth of a locking element plus the dia. of a locking element. The arrangement has reduced space requirements since the mandrels can be removed at the mill stand or at the end of the run-out table, and stripping devices etc. are not required.
