Title: Plastics hand guard for rifles
Inventor: MOELLER TILO
IPC: F41C23/16
Filed: 1969-12-03
Abstract: Hand guard for automatic rifles and light machine guns comprises a shell of foam plastics material, pref. polyurethane, with a closed surface.

Title: Pyrocatechol manufacture from a chloro - phenol
IPC: C07C37/02
Filed: 1970-08-27
Abstract: Pyrocatechol is prepared by treating o-chlorophenol with 4-8 mole equivalents of alkali-metal hydroxide in aqueous solution at 60-85% Concentration by weight, in the presence of a copper hydrolysis catalyst (0.5% by weight of Cu relative to the weight of o-chlorophenol) at 160-240 degrees C. Preferably the alkali concentration is maintained at the above level throughout the reaction. This method minimizes the production of resorcinol and polynuclear products, and gives good yields in reasonable reaction times.
Patent DE-2063430-A1 (DE)
Title: Composite x-ray shielding material - for lining rooms etc in the form of plates or sheets
IPC: G21F1/12
Filed: 1970-12-23
Abstract: The material has reduced back-scatter characteristics and is based on a central layer of lead plate or foil coated on both faces with bitumen. The bitumen layer nearest to the X-ray sources carries an outer layer of material with a low atomic number esp. of Al. For ease of application, either the rear layer of bitumen or the front layer of Al may be coated with an adhesive covered in turn with a tear-off protective film. For sealing the joints between adjacent panels or strips, a narrow laminated strip of the same layers is used, the front layer of Al in this case being wider than the remaining layers and coated on the rear face of the protruding skirts with an adhesive layer.

Title: Switched socket with terminals - has cable terminals and sockets which are integral with cam switch
Inventor: SPIEKERMANN ERNST
IPC: H01R13/64
Filed: 1973-06-02
Abstract: Spring strip U-section sockets are provided along one side of a socket housing.

Title: Casing enclosed wound capacitor - has metallised electrodes and space between capacitor and casing filled with cast resin
Inventor: WESTERMANN WILHELM
IPC: H01G4/224
Filed: 1973-10-19
Abstract: The self-regenerating capacitor has metallised plastics coil(s) mounted in a cup-shaped casing. The spaces between the wound capacitor roll and the casing wall is filled with a cold curable casting resin which hardens during 6-12 hours at temperatures between 30-60 deg.C. The resin fill reaches up to the upper edge of the wound capacitor roll. This cast resin exerts only slight shrinking stresses onto the wound capacitor roll without impairing its regenerability. The casing closure is formed by a top layer of hot hardenable resin, i.e. one which hardens during 1-2 hours at 100 to 120 deg.C.
Patent DE-2353203-A1 (DE)
Title: High duty laser output mirror - prevents diffusion by nickel plating of copper carrier before gold vapour deposn.
Inventor: FRANK FRANK DIPL-PHYS
IPC: H01S3/08
Filed: 1973-10-24
Abstract: Output mirrors for high-duty lasers are produced by applying on a perforated carrier, made of copper first molten tin or a 2-component casting resin to fill up the perforations. After grinding and polishing, the filling is removed by fusing and an Ni or Cr layer id deposited by electroplating. The mirror layer of gold is finally vapour deposited on this layer. This keeps the edges of the perforations and of the periphery completely sharp, resulting in extremely low absorption and diffraction losses. The diffusion of the gold mirror coating into the copper of the mirror carrier is also securely prevented.
