Title: Polymer compsn. contg. additive partic. glass spheres - adhesion being improved by etching
Inventor: WINTERGERST SIEGMUND PROF DR I
IPC: C08K9/02
Filed: 1974-11-05
Abstract: Polymer compsns. contg. a reinforcing additive (partic. glass), the adhesion of which to the polymer is improved by etching. The process is suitable for treatment of glass prior to incorporation in thermoplastics such as styrene, polyethylene and polypropylene the adhesion of which to glass is very little improved by previously known methods e.g. silane, or chromate-based sizing. Polyethylene with 15 wt. % etched glass fibre addn. has the same strength as is obtd. with 40 wt. % addn. of silane-treated glass fibre With 40 wt. % addn. of A-glass as etched spheres the tensile strength is more than double that obtd. by using silane-sized glass spheres. Cheaper A-glass can replace expensive E-glass.

Title: Standby or emergency electrical supply - uses filter circuit to provide power during transition period when normal supply fails
Inventor: UDVARDI-LAKOS JANOS DIPL ING
IPC: H02J9/06
Filed: 1974-10-10
Abstract: The electrical supply equipment is designed to provide power during the breakdown of normal supplies, the transition from one supply to the other being uninterrupted. The design is intended to reduce the losses due to two stage conversion from battery d.c. to output occurring in some systems. Any pause between supply breakdown and standby operation is catered for by the energy stored in a filter in series with the load. Two or three phase systems are accommodated, the standby supply being fed into the load circuit when signals derived from load circuit transducers are allowed to pass to a d.c. powered oscillator.

Title: Coil winder for toroidal coils of very thin wire - uses insulated tape wrapping and is mounted in circular slot in spring-loaded roller system
Inventor: ROTH KARL HEINZ
IPC: H01F41/068
Filed: 1975-02-10
Abstract: The coil winder for toroidal coils of very thin wire is wrapped with insulated winding strips supplied from a feed with a mechanism gripping around the toroidal core. The latter is mounted between circular slots in a roller system consisting of drive and guide rollers. Some of the guide rollers can be moved outwards by the tension of the toroidal coil, due to the action of a spring. The tension of the toroidal coil is initially set at a relatively high value to produce a relatively high friction during the winding process, keeping the bearing of the supply coil upright. The friction produced by the pull of the winding strip on the toroidal coil is supplemented by an additional tensile force caused by the friction of a brake on the front face of the hub of the supply coil.

Title: Applying wax spacer pips to edges of ceramic tiles - preventing glazed tiles from sticking together during baking
Inventor: ARNOLD ULRICH
IPC: F27D99/00
Filed: 1975-05-28
Abstract: In the application of spacer pips made of a completely combustible, glaze-repellent, protective material onto at least one surface of continuously moving ceramic bodies, esp. tiles, at least one blowing channel is filled by periodic immersion in a bath and then move to a position where a jet of air can blow the material out of the channel onto a surface of the tile which is parallel to the direction in which the tile is moving. Each spacer pip is pref. formed of several layers obtd. using several blowing channels. The device pref. includes a conveyor for the tiles and a rotating disc contg. blowing channels near its periphery, the channels being immersed in a bath of the protective material by rotation of the disc. Applying pips of wax to the edges to tiles prevents the glaze on one tile reaching that on an adjacent tile during baking.

Title: Expanding wall plug fastener with central stud - has bellows folds which expand radially when compressed axially by pulling stud
Inventor: HOFFKNECHT MANFRED
IPC: F16B13/06
Filed: 1975-08-07
Abstract: The expanding plug fastener comprises a hollow plug body (2), a part of which has bellows folds. The body contains a tension stud (3) with its head (4) at the inner end of the hole. When the rod is tensioned by a suitable tool the consequent axial compression of the folds causes them to expand radially against the wall of a hole into which the body is inserted. The head snaps off when the tension exceeds a given magnitude, and allows the rod to be removed. There may be two axial sections (2a, 2b) of the body with bellows folds. One of the sections may have an axial slot to facilitate the radial expansion.
