Patent DE-2415962-A1 (DE)
Title: Arrgmt. for milling keys using a master key and probe - in which probe and cutter are moved in one direction lifted clear and returned
Inventor: COCKROFT DARREL
IPC: B23C3/35
Filed: 1974-04-02
Abstract: The arrangement consists of a slide with two platforms. The slide can be moved up and down along four guides, while the guides can be moved to and fro. The up and down movement is derived from a cam driven from a motor, while the to and fro movement is obtained by an eccentric and connecting rod. Both the eccentric and the cam are driven from the same motor so that the slide is lifted once during one to and fro movement. A motor with cutter is mounted on one of the platforms of the slide, while a probe holder and probe are mounted on the other platform. The probe lies against a master key while the cutter engages with a blank. During the movement of the slide, the cutter and probe are moved from the end of the key towards the grip part. Probe and cutter are then lifted as the slide is lifted by the cam, and are returned to their start position.

Title: Earth gravity powered electrical generator - uses potential energy of weights suspended by ropes
Inventor: WENK PAUL DR
IPC: H02K7/18
Filed: 1974-04-11
Abstract: Electricity is generated by rotating the generator by gravity. The gravity drive consists of weights attached to a rope or chain. This rope is wound on the drive shaft and the weight is allowed to drop under controlled conditions to ensure uniform rotating speed. The rope is rewound by means of cheap rate nighttime electricity or by muscular power. The plant can be stationary or mobile. The driving weights can be made to drop underground. The dropping period can be adjusted to a given length of time. The conversion device which resembles an early clock is used to supply energy where the energy of the sun and wind or nuclear energy is not available in sufficient quantities.

Title: Portable table mounted baby chair with tubular frame - has two pincer-like frame members to clamp table without extra long supporting struts underneath
Inventor: KIESERITZKY GEB TRINKIES CLAUD
IPC: A47D1/10
Filed: 1974-09-11
Abstract: The tubular framework has two members connected together for swivel movement about axes of rotation (3, 3') in the form of pincers.
