Title: Installation of vehicle wiring - involves fitting of cable loops before painting, and cable terminals are protected by wax
IPC: H02G3/00
Filed: 1976-02-26
Abstract: The system of installation of vehicle wiring is designed so that assembly time may be reduced and the wiring arrangement may be rationalised.

Title: Peeling and sectioning device for vegetables or fruit - includes a roller which pushes the vegetable through a sharpened grille
Inventor: GERMAIN JEAN-PAUL
IPC: A23N7/00
Filed: 1976-03-31
Abstract: A machine for peeling and cutting up fruit or vegetable in block form with skin on one side only uses a roller to press the block against a cutting grille which advances tangentially to the roller, in the same direction and at the same speed as the roller. A blade separates and lifts skin away on one side of the grille as cut prod. is pushed through to the other side of the grille. The grille has sharpened cutting edges which ensure that cut prod. pieces are not in any way crushed or bruished. The cutting edge of the skin removal blade faces the discharge line of the roller and the blade can be fixed or rotary. The grille can be formed in the surface of a rotary table or in the circumference of a drum. Alternatively, the grille can be carried on a table which reciprocates beneath the pressure roller.

IPC: H01L23/532
Filed: 1978-06-14
Abstract: In the prodn. of a semiconductor device with a first wiring layer, mainly of Al, on a first insulating film, a second insulating film is formed on the wiring layer, contact hole(s) are formed on this and a metal film, which reacts with Al, is formed on the first wiring layer in the contact hole(s). A second wiring layer, mainly of Al, is formed, at least in the contact hole(s), to cover this metal film and the first wiring layer and the metal film are reacted by heating the substrate. Devices with multiple wiring layers can be produced without great expense and without faulty connections between the upper and lower layers. The technique is useful in the prodn. of highly integrated circuits.
