Title: Windscreen wiper installations for motor vehicles
IPC: B60S1/34
Filed: 1964-11-18
Abstract: 1,078,856. Windscreen wipers. ROBERT BOSCH G.m.b.H. Nov. 18, 1964 [Nov. 19, 1963], No. 46879/64 Heading A4F. A windscreen wiper installation comprises two wipers 2, 3, a wiper motor 4, a crank pin 15 coupled to be rotated by the motor, oscillating cranks 11, 17 connected to the wipers for moving them to-and-fro, a first rigid connecting link 13 between the crankpin and a pivot 12 on one 11 of the oscillatory cranks for moving one wiper 2, and a second connecting link 18 between a pivot 19 on the first link and a pivot on the other 17 of the oscillatory cranks for moving the other wiper so that the wiped fields 20, 21 overlap somewhat at their inner extremes and the wiper arms move to and fro in counter movement without the wipers colliding. The installation drives the wipers in opposite directions in such a manner that they are in their outer positions, as shown, at the same time but are then moved at different angular velocities. During 180 degrees movement of the crank pin 15, the wiper 2 is moved through 104 degrees to its inner limit position and during the next 180 degrees is returned to its initial position. The wiper 3, however, only reaches its innermost position before the crank pin has moved 180 degrees and by the time the crank pin has moved through 180 degrees has left the overlap area 26 and is held substantially stationary while the other wiper moves in and out of the area, both wipers then being returned at substantially the same speed to their initial outer positions. Rods 22, 23 are pivotally connected to the wipers 2, 3 and fixed pivots 24, 25 so that the wipers are horizontal in their outer positons and vertical in their inner positions and are substantially parallel to the direction of flow of air currents over the windscreen of the vehicle in their intermediate positions to reduce the danger of the blades lifting off the windscreen.

A method of producing a smooth-surfaced epitazial deposit of semi-conductive material on a substrate comprises reacting a halogen transport element with a source of both semi-conductive material and cadmium and decomposing the vapour so formed on to a heated substrate, the deposit having a cadmium concentration of the order of the limit of solubility for cadmium in the semi-conductive deposit. As shown, an N-type gallium arsenide (GaAs) wafer 6 is placed in a sealed quartz reaction tube 1 together with a source 3 of GaAs, a source 4 of iodine or other halogen, and a source 5 of cadmium. The materials of sources 3, 4 and 5 are heated by coil 2a, whilst wafer 6, which may be masked, is heated by coil 2b.

A Group II element such as zinc may be included in the GaAs source 3 or the cadmium source 5 to produce greater impurity concentrations in the deposited layer. An " open tube system of vapour deposition may also be used. The substrate may also be of P-type material.
