Patent DE-1801440-A1 (DE)
Title: Precision wire resistors with vitreous coating - and nonfusing intermediate layer over 180oc surface
Inventor: KASPER DIPL-CHEM DR EBERHARD
IPC: H01C3/06
Filed: 1968-10-05
Abstract: The resistor wire is first given a non-fusing intermediate coating before the vitreous final coating is applied, to make it suitable for working temperatures exceeding 180 C on the surface. The intermediate layer is a silicone cement which is applied by immersion, spraying or rolling, baked at 150 to 200 C to ensure a network structure for the silicones and then converted at 400 to 800 C into an oxide-ceramic frit. The inert fillers used for the silicon cement are aluminium oxide, mica and/or beryllium oxide. Compounds on an aluminium-organic base are used as hardeners. Advantages are the elimination of any depassivation and the narrow tolerances (plus-or-minus 0.5-2%) obtainable in the resistance. The cushion action of the silicone frit compensates for any difference in thermal coefficient of expansion. Two to three coatings of vitreous enamel are sufficient to ensure a breakdown strength of at least 5 kV. The good thermal conductivity of the silicone ensures a better heat equalisation.

Title: Shuttering pipe for concrete columns
Inventor: WERNER PHILIPP DIPL-ING
IPC: B21C37/12
Filed: 1968-12-04
Abstract: Shuttering pipe for concrete columns. Applies to columns etc. in the building industry, made from spiralled tape or strip whose sides are pleated together. Weakened lines on the strip run parallel to the pleatings. The strip could have two weakened lines, well spaced but each close to one of the pleatings. These weakened lines could be made by rolled shears whose knives expose the strip to a shearing load below the tear stress level. Strip should be paid off a reel for weakening by the roller shears ahead of the edge shaping rolls or unified with these and so on steadily via feed rolls to a coiler (spiraller) station to produce the finished shuttering.

Title: Low-viscosity synthetic rubber latices
Inventor: PETER SCHAB DIPL-CHEM DR
IPC: C08F212/08
Filed: 1969-05-22
Abstract: Polyvinylacetate (I) is added to a latex in the form of an aqueous dispersion, preferably 0.01 to 3 parts (I) in form of dispersion containing 3 to 20% solids, with respect to 100 parts of solids in the latex.

Patent DE-2156364-A1 (DE)
Title: Pneumatic damper - with overload safety device used in pressure casting appts
Inventor: HODLER FRITZ
IPC: F16L55/053
Filed: 1971-11-12
Abstract: Danger of the piston of a damper being pushed through the bottom of its cylinder owing to escape of the damping medium is avoided by having a conically shaped spigot in the centre of the underside of the piston, the spigot working in a slightly larger orifice in the cylinder end wall. As the piston approaches its bottom point, the wider part of the spigot comes within the orifice, thereby restricting flow of hydraulic medium to the underside of the piston, creating a partial vacuum which rapidly halts further movement.
