Title: Laundry folding equipment - has a moving folding blade in transfer zone between two conveyors triggered by photo-electric detection
Inventor: GEIGER FRIEDRICH
IPC: D06F89/00
Filed: 1974-04-26
Abstract: Appts. for folding articles of laundry uses a transfer action between a feed conveyor and an opposing and slower-running conveyor, with a folding blade pivoting in the transfer zone of each conveyor. Along the carrier level of each conveyor control impulses are generated from a light tube or the like, which trigger a number of photo-electric units arranged on the other side of the assembly. The system gives a laundry folding action, under control to give positive folding, but occupies relatively little space.

Title: Safety non splinter car mirror - is coated in plastic layer and thin anti-scratch coating
Inventor: SCHULD HELMUT
IPC: B60R1/02
Filed: 1974-05-15

Title: Low-noise-level fluid concrete consolidator - with bars passing down from fixed plate through oscillating plate into concrete
Inventor: THOMAS RUDOLF
IPC: E04G21/06
Filed: 1974-06-12

Title: Process for splicing fine wires - by welding inside a close fitting ceramic cylinder
Inventor: KONOMI YOICHI
IPC: H01R4/02
Filed: 1974-12-05
Abstract: The wires to be joined (1, 1') typically of copper or aluminium, are threaded into a ceramic cylinder (2) dimensioned to give the required clearance. Electrodes (4, 4') placed either side of the cylinder then pass a predetermined current through the wires causing them first to fuse and then to part. The cylinder is then removed and what was the free end of the wires discarded. The use of the ceramic cylinder prevents the sputtering of metal from the molten wires and also assists in excluding oxygen. The resultant joint is thus very sound and neat, and of a resistance typically some 40% lower than is obtainable with an unprotected joint.

Abstract: The citrus fruit peeler comprises a handle (10) and blade (1) which is to be inserted at its point between the peel and the fruit and is provided with a cutting edge (1) which is formed by a projection protruding somewhat less than the thickness of the fruit peel and located at a point remote from the front sideside of the end section (2) of the blade which is displaceable between the peel and the fruit in the peeling direction. The cuter is designed as a flat wedge with a straight cutting edge and the peeler has a curvature of about a quarter of the fruit perimeter extending from the head of the end section (2). To peel fruit e.g. an orange, an equatorial cut is made to the depth of the pith between the fruit and the peel whereupon the two peel halves are then removed by removing the pith from the cut edges spirally to the points at each end. Until finally the two complete halves of peel are detached. THe peeled orange can then be stored in the complete peel casing until required for eating without danger of drying out.

Title: Production of asymmetric enclosure - stamped out plate is rolled to hollow cylinder and introduced between former and guide block
Inventor: GOTO YOSHITAKA
IPC: B21D51/10
Filed: 1975-05-22
Abstract: Production of an asymmetric enclosure especially in the form of a chamfered hollow cylinder where a plate stamped out in the form of a development of the hollow cylinder of the enclosure is rolled to a hollow cylinder (MC) and introduced between a former (5) and a guide block (6). Then, while maintaining the contact of the meeting edges of the hollow cylinder, the edge which creates the asymmetry (e), is formed in several stages to the prescribed shaped of the flange.
