Title: Edge grinding of glass panes - using profiled conveyor belt feeding pane past row of grinding wheels
Inventor: BANDO SHIGERU
IPC: B24B9/10
Filed: 1975-12-03
Abstract: In a machine for edge grinding glass panes fed past a row of grinding wheels, the panes are supported by and conveyed between, two parallel conveyor belts, the reverse side of one belt (I) sliding over a backup plate while pressure rollers push the two belts and the pane towards the backup plate. The novelty is that the pane is pushed by the pressure rollers near the edge being ground so the pane rests firmly against the edge of the belt (I). Belt (I) is pref. thicker at its edges than in the middle achieved by using either a concave surface on the side of the belt (I) in contact with the pane or by using pads along each edge. The other conveyor belt and the pressure rollers pref. have a shorter width than belt (I) and the backup plate. The grinding wheel is pref. mounted on a shaft which is elastic in both the radial and axial directions. Use of a flat back-up plate and a concave profile on one belt allows easy construction of the arrangement.

Title: Remote-controlled vehicle steering system with fail-safe - stores control data for comparison with positional signals from actuator
Inventor: DOBLER KARL ULRICH DR ING
IPC: B61L19/06
Filed: 1976-03-02
Abstract: The points control for automatically controlled vehicle systems is for vehicles having their own remote-controlled steering. The vehicle and the central controller are fitted with three registers in which the control data can be stored. The command signal for the steering direction received via the transmission link is stored and compared with the actual steering mechanism position in a comparator. If they correspond prior to the next direction change the vehicle is allowed to proceed. As a back-up, after the vehicle has passed the junction points, a second comparator compares the command signal from the first store with that of a third register whose signal is derived from a steering mechanism repeater. If the two signals do not coincide, an emergency stop is initiated.
