Title: Small cards for punching for accounting purposes
Inventor: O'REILLY EDGAR DIPL ING
IPC: G07B11/05
Filed: 1989-05-03
Abstract: The use of the new small readable cards enables pre-punching to be dispensed with, since the readability is achieved by means of transparent ink cutouts. Furthermore, the longitudinal slots in the fields of the small readable card make possible a simpler positioning of the perforating punch, especially under poor light conditions. Furthermore, a mechanical scanning in the reading device is possible by means of the bulges. The elongated positioning pin permits an especially simple latching in the longitudinal slot.

Patent DE-4038137-A1 (DE)
Inventor: MUELLER WILLI
IPC: B25J9/04
Filed: 1990-11-30
Abstract: The manipulator (1) serves in particular to feed machining equipment and to palletise the machined workpieces. It has a rigid swivel arm (16) of given length and a gripping device (18), arranged at the free end of the swivel arm (16), as well as a support (15) which is spatially orientated in a fixed manner and is mounted in a vertically displaceable manner on a horizontally movable pedestal (10, 11) and on which the swivel arm (16) is laterally mounted.
