Title: Ski binding with automatic release under excessive force - has catch which returns to initial position after release of boot (OE 15.4.78)
Inventor: KROB ERWIN ING
IPC: A63C9/08
Filed: 1977-12-20
Abstract: The ski binding automatically releases the ski from the ski boot when subjected to an excessive force. The clamping levers are held against the sole of the ski boot by the spring n14) that acts on a plate (20') which presses against the curved lever surfaces. The outward swinging of either lever when releasing the ski boot pushes the wedge (9), forming part of the rod (3), against a second wedge forming part of the housing (1). This action depresses the rod (3) so that the inner arms of the levers are no longer restrained by the wedge and allow the levers to return to their original positions.

Title: Altering slab width during continuous casting of steel slab - by lowering flexible insert into mould to form temporary mould wall cast into the slab
Inventor: BUSCHMANN HORST
IPC: B22D11/08
Filed: 1978-09-25
Abstract: During casting via a cooled mould, a steel insert with a compsn. corresp. with the steel being cast is moved from a horizontal position above the mould to a vertical position, so it is partly immersed in the molten steel adjacent to an adjustable narrow wall of the mould. The insert welds onto the solidified skin of the steel in the mould and thus forms a self-supporting wall retaining the semi-solid steel in the mould while the narrow wall is moved outwards to increase the width of the cast slab. Both the oscillation of the mould, and the extn. of the slab out of the mould, can be continued while the mould width is increased. There is no harmful change in the cooling rate of the slab.

IPC: B62B13/12
Filed: 1978-11-11
Abstract: The sledge has two runners (16) supporting two cross members (18) with central supports (32-38) which carry the seat (40). The cross members are also connected at each end to outer longitudinals (30) forming rectangular linkage with corner connections (31).

The connections (20) between the runners and the cross members each consist of a U shaped strap (21) integral with the runner with sloping arms between which is retained a shaped block (22) integral with the cross member. A quick release pin (23) passes through the arms and the block, acting both as a securing device and hinge pin. The hinged connections allow both runners to be tilted by tilting the seat, when negotiating a curve. This action is assisted by the movement of one runner ahead of the other. The longitudinals (30) are used for gripping and steering. Resilient suspension is included.

Title: Rail track aligning system - has reference chord wires sensed by measuring devices to produce track error signals
Inventor: BECKMANN HELMUTH VON
IPC: E01B35/00
Filed: 1978-12-06
Abstract: The aligning device for monitoring the curvature of a track and adjusting the track successively to correct the curvature incorporates two taut wires mounted on a car or cars running on the track. The wires define two chords each extending between a pair of spaced points on the track centre line. A first measuring device is located nearer the rearward point of the first chord derives a voltage which is sampled at equal intervals, as the aligning device passes along the track. The voltages are summed and averaged electrically and a voltage equivalent to the mean displacement of the track from the first chord is obtained. The second measuring device is located nearer the rearward point of the second chord and derives a voltage equivalent to the actual displacement at that position of the track with respect to the second chord. This voltage is compared electrically with the mean voltage and an error voltage is derived and used to operate a servoassisted aligning mechanism.
