Title: Automotive drum brake anchor plate - has through apertures releasably closed by caliper lining covers to allow inspection for wear
Inventor: FUCHS JOSEF
IPC: F16D66/02
Filed: 1976-08-18
Abstract: The vehicle drum brake is activated by brake calipers and has an anchor plate for fixture to the wheel bearing of the vehicle. At least one through aperture in the anchor plate at the level of the brake caliper lining is tightly closable. Each lining on each caliper has a cover which corresponds to the shape of the through aperture and thus closes it, but is releasable. This releasable connection is prevented from rotating.

Title: Rough, eroded and artistic surface on marble or onyx panels - obtd. by sand blasting or etching
Inventor: ALARI MARCO
IPC: C04B41/53
Filed: 1977-07-11
Abstract: A panel is provided with a profiled surface, by an erosive or etching treatment. The treated surface is pref. coated with a matt, colourless and transparent lacquer. The profiled surface is pref. obtd. by sand blasting at a pressure of 3-15 (esp. 12) kg/cm2, for a time of 15 mins./m2, using a tubular sand nozzle. Alternatively, the profiled surface may be achieved by etching with acid. The sand blasting produces an artificial erosion which can only be achieved by up to 1000 years exposure in natural conditions, and a rough surface is obtd. with a very artistic effect and non-slip properties so the marble has new uses, e.g. as a coating on the bottom surface of swimming pools. Surface scratches are less visible.

Title: Contacting doped semiconductor crystal through silicon layer - using oxidn. inhibitor over contact point, allowing self-alignment and giving planar surface
Inventor: MURRMANN HELMUTH DR RER NAT
IPC: H01L21/285
Filed: 1977-10-27
Abstract: Contacting of a doped semiconductor crystal by means of a doped Si layer involves deposition of a Si layer on the contact points on the surface of the crystal and on a layer of organic insulant around these points. The novel feature is that the Si layer is covered with an oxidn. retarding layer, at least over the contact points, and the other parts of the layer are oxidised completely. The contacts between the metal tracks and the polySi electrodes need not be made near the semiconductor monocrystal to be contacted, but at less critical pints, avoiding impairment of the pn-junction. Self-alignment is possible and the areas bearing the conducting tracks are as planar as possible.
