Abstract: 235,989. A.M.A.C., Ltd., and Guy, W. L. April 12, 1924. Control mechanism. - In Bowden &c. control devices of the kind in which two or more actuating levers are coaxially mounted upon a fixed base such as a clipped attachment to the handlebar of a motor-cycle, independently adjustable friction means are provided to prevent uncontrolled movements of the respective levers, the first lever being mounted upon a central stud attached to the base and the second and additional levers being mounted between relatively adjustable flanges of reels which are mounted non-rotatively upon the stud and are bodily adjustable against the first lever to press it against the base. In the duplex control device shown, the first lever B is mounted to rotate upon a fixed stud A<3>. The second lever D is mounted upon a reel E having a fixed flange E<2> and an adjustably screwed flange E<3>, rotation of the reel upon the stud A<3> being prevented either by co-engaging flats or by engagement of lugs E<5> upon the flange E<2> with the usual segmental wall A<4> extending upwards from the base A. Belleville washers or the like C, F being interposed, the frictional grippreventing movement of the levers is regulated, in the case of the lever D, by adjustment of the flange E<3> and, in the case of the lever B, by bodily adjustment of the reel. To lock the flange E<3>, a washer G, engaging a squared part A<6> of the stud, is provided with a lug G<3> adapted to engage one of six radial grooves E<6> in the end of the screwed boss of the flange, the arrangement providing for fine adjustment. The reel together with a dished cover H is retained on the stud by a set screw J tapped into the end thereof and serving to press the reel bodily against the hub of the lever B to the desired extent. A form in which two reels are mounted upon the stud and serve to press a third lever against the base-plate is also described. The Provisional Specification describes also an arrangement wherein the dished cover is non-rotatably mounted on the stud, the end of which is externally screwthreaded to receive a cap nut, and the adjustable flange of the reel is formed with a notched periphery adapted to be engaged by a lug or tongue on the cover in substitution for the locking washer G.

Title: Method of building up a crystalline material
IPC: H01L21/00
Filed: 1962-03-13
Abstract: In a process of building up semi-conductor crystals, a semi-conductor substrate and a semi-conductor coating material are heated in an enclosure so that a temperature differential exists between the two, the substrate temperature being sufficient to volatilize part of the semi-conductor and thus form a fresh surface, the temperature differential then being reversed so that the coating material is at a higher temperature and is volatilized and deposited on the cooler freshened surface of the substrate.  The following materials may be formed:  GaAs on GaAs; GaAs on Ge; AlP on Si; GaP on Si. The process normally produces a P-type deposit on N-type substrates or vice versa and the process may be carried out under vacuum which may contain active impurities such as S, Se, Te, Zn and Cd, or in a carrier gas such as chlorine.  It is preferable that the unit cell size of the substrate and the coating material are approximately the same size.ALSO:In a process of building up semi-conductor crystals, a semi-conductor substrate and a semi-conductor coating material are heated in an enclosure so that a temperature differential exists between the two, the substrate temperature being sufficient to volatilize part of the semi-conductor and thus form a fresh surface, the temperature differential then being reversed so that the coating material is at the higher temperature and is volatilized and deposited on the cooler freshened surface of the substrate.
