Title: Finger-print comparator using photodetector - detects coincidence between reference print and moving projection of actual print
IPC: G07C9/00
Filed: 1979-12-24
Abstract: The finger-print is applied to the sloping face of a prism. The finger-print is projected optically through a reference finger-print (1) on a transparent plate. Coincidence between the projected finger-print and the reference finger-print causes a first electrical output at a photodetector (12) whilst noncoincidence causes a second output. The image of the finger- print on the prism passes through a device (9) that causes it to move continuously in a given manner (e.g. in a spiral) in a given plane such that it moves in the same manner over the reference finger-print. If the finger-prints are identical the light incident on the photodetector will be greater than if they are not identical. The comparator can be used for comparing a finger-print on a security card with the user's actual finger-print in order to gain access to a building. The comparator can also be used to compare patterns other than finger-prints.

Title: Apparatus for welding seams of limited length
Inventor: ROSENKRANZ HERBERT
IPC: B23K37/02
Filed: 1981-01-31
Abstract: The invention relates to an apparatus for welding seams of limited length, in particular fillet seams arranged between stiffeners, with the use of a feed system mounted on a rail and carrying welding torches. The invention achieves the object of creating a drive and rail system which can be adapted to any seam length and can be adjusted to the component surface, the entire seam, including the start and end of the seam, being continuously weldable. This is achieved by a two-piece rail which is variable in length in a sliding manner with the use of a positive-locking connecting piece. The feed system is guided by means of double-V-rollers on each longitudinal section of the rails at least in one V-roller guide groove pair so that the coupling point of the rails can be crossed smoothly. The start and end of the seam can also be welded completely by two welding torches being arranged on the feed system in a leading and trailing position in the welding direction. <IMAGE>

Title: Foot for slalom poles
Inventor: STEINHAUER FRITZ
IPC: E01F9/627
Filed: 1981-02-24
Abstract: A foot for slalom poles consists of a tubular insertion pole (10, 12) which is of multi-part design and at the lower end of which a chisel-like or drill-like tip is located. The upper end of the insertion pole (10, 12) has a threaded hole (42) into which is releaseably screwed an elastic member (18) which is fixedly connected to a holder (14) into which a slalom pole (16) is inserted, with the optional use of spacer sleeves (22, 24). The insertion pole (10, 12) is driven or twisted into the ground, use being made of an impact piece or twist grip temporarily screwed into the insertion pole instead of the holder (14) with rubber body (18), after which the impact piece is unscrewed and is replaced by the holder (14) with rubber body (18). Thanks to the rubber body the holder with the slalom pole can be tilted through 90 DEG  and more in all directions. The restoring force, however, is sufficient to bring the pole back automatically into the vertical position. The new slalom pole foot permits easy but reliable insertion into the ground and guarantees optimum safety, since the pole immediately tilts away into a position immediately above the surface of the snow when it is touched by a skier. <IMAGE>
