Title: Silver-free gold-palladium dental alloy - contg. indium and ruthenium as hardening components
Inventor: EURICH KLAUS
IPC: A61K6/04
Filed: 1980-05-21
Abstract: A silver-free, gold-palladium dental alloy contains (by wt.) 3-10% In and 1-4% Ru. When the alloy is to receive a fired ceramic coating, it pref. contains 1% Sn. Pref. when the alloy contains 10% In then it contains 3.5% Ru. Compared with the alloy of DE2814943 the alloy does not contain Ga (which hinders prodn. of oxide-free, dense castings) and Sn (which causes embrittlement and makes the alloy less useful e.g. for dental bridges) as hardening components. Only a small amt. of Sn, as adhesion promoter, is required in alloys which receive a fired ceramic coating. The alloy is suitable for receiving various types of ceramic coatings since only the Au and Pt contents have to be varied to match thermal expansion coeffts. and this variation does not affect the mechanical properties of the alloy. Specification printed 25.2.82.

Title: Mine-working support and striding abutment alternating advance - involves rocker swinging between slide plate settings, preventing faulty guidance
Inventor: SCHINK BERNHARD
IPC: E21D23/10
Filed: 1980-11-21
Abstract: The connecting head is for the abutment. There is a two-way-activated striding forwarding cylinder hinged to a support unit, and a piston-rod with a hinge for the head and plate movable with it. They are incorporated in a device for alternately advancing units of a travelling long-face support system and striding abutment working with this, in a mine. The slide plate is located near the ends of the guideways on the connecting-head side. The rocker swings from the plate's flat setting on the shield skid into a steep plate setting ahead of the leading skid edge below the device. This precludes incorrect abutment and/or skid guidance resulting from dusting material collecting on the skid front edges.
