Patent DE-2556871-A1 (DE)
Inventor: SCHWARZ GUENTER
IPC: A63C5/065
Filed: 1975-12-17
Abstract: The mountable body is trapezoidal in a known fashion. In order to permit its baseplate (5), by means of which the said body is fastened to the ski surface, to exhibit inherent elasticity, a cross-sectional restriction is provided in each case between the said baseplate (5) and the side walls (3, 4). A restriction of this type is achieved by means of slit-shaped recesses (15 to 18). As the baseplate is therefore not made rigid by the side walls to any substantial extent, it is able to follow the bending movements of the ski. <IMAGE>

Title: Bimetallic catalyst including silver - formed by displacing second metal from solution by first metal
Inventor: CUSUMANO JAMES A
IPC: B01J23/755
Filed: 1976-02-16
Abstract: A bimetallic catalyst is produced by contacting silver, either as a powder of surface area 0.01-100 m2/g or on a refractory metal oxide support, with an aqueous solution of a salt of gold, iridium or platinum. In a preferred embodiment a solution of chloro auric acid contains 1 x 10-5 to 1 x 10-3 g. of gold per 1 m2 of available silver surface. As the catalyst is formed only on the surface of the silver the image of the expensive second metal is minimised. Furthermore the process provided control of surface composition and thus of catalytic activity.
Patent DE-2607835-A1 (DE)
Inventor: BUKENHOFER HEINZ
IPC: A63C9/20
Filed: 1976-02-26
Abstract: The cross-country ski binding is composed of a baseplate (210) with lateral guide walls (212) on both sides, on one of which walls (212) a holding-down device (220) is mounted so as to be pivotable about a pivot axis (260) situated in the longitudinal direction of the binding, from an entry position pointing upwards into a locking position which is folded down onto the other lateral guide wall. A releasable belt (254) in the form of a catch holds the holding-down device in the locked position. The transverse extent of the holding-down device (220) ensures that the baseplate (210) does not have to be extended forwards beyond the lateral guide walls (212) in order to support the pivot mechanism for the holding-down device. Furthermore, a cross-country ski binding of such a design is simpler to manufacture and convenient to handle. <IMAGE>

Title: Electric power generator utilising chimney draught - has series of propeller turbines rotated by flue gases in chimney
Inventor: SCHILLER FRIEDRICH
IPC: F03G7/04
Filed: 1976-03-29
Abstract: A chimney (11) rises above a combustion chamber (13).
