Patent GB-938917-A (GB)
Title: Method of producing discs of monocrystalline semiconductor material
IPC: C30B15/20
Filed: 1962-03-23
Abstract: Monocrystalline semi-conductor discs for use in the manufacture of semi-conductor devices or as seed crystals are produced from a monocrystalline rod of uniform diameter having its longitudinal axis orientated in a crystallographic direction such that planes along which cleavage can readily occur are perpendicular to the axis.  The rod is notched at intervals along its length and thereafter cleaved at the notches by application of lateral pressure and/or tension. For instance a germanium or silicon rod grown from a melt with the 111, 110, 221 or 112 crystallographic direction lying along its axis is notched by a diamond point or edge and cleaved by a high quality steel point applied obliquely to the rod at the notches.  If the resulting discs are kept in an inert atmosphere they may be used in semi-conductor device fabrication without further clearing or etching.  Otherwise only a light etching is required to remove oxide films.  Particularly smooth uniform surfaces are obtained if the cross section of the rod exceeds the square of the thickness of the discs.

Filed: 1975-03-19
Abstract: 1491756 Magnetrons VARIAN ASSOCIATES Inc 19 March 1975 [22 March 1974] 11406/75 Heading H1D As described, the outer cavity of a coaxial magnetron (or the inner cavity of an everted coaxial magnetron) incorporates an array of fins 14, Fig. 3, projecting inwardly from either the circumferential wall or one of the end walls, adjacent vanes being connected by a pair of back-to-back PIN diodes having a lead 22 from their point of connection passing through the cavity wall, via a feed-through insulator 23, to a shift register source of bias signals, biasing of a pair of diodes to the conductive condition shorting out the appropriate pair of vanes, to produce a discrete change in magnetron frequency. If the concomitant decrease in Q can be tolerated, a continuous frequency change between the initial and final values may be obtained by gradual increase of the diode forward bias to the fully "on" state. In a further embodiment, Fig. 7, a segmented conductive ring, supported from the cavity wall by a ceramic insulator 29, has a PIN diode 32 in each segment, the segment joins being connected alternately to the resonator wall via leads 33, and to the bias source via leads 34. In the arrangement shown in Fig. 11, ferrite members 41, mounted adjacent the wall 43 of the cavity, are subjected to the magnetic fields produced by windings 45 on an external yoke 44 portions 42 of which extend through the cavity wall. Reference is made to a further arrangement which employs, in place of PIN diodes, ferroelectric ceramic members, e.g. of barium titanate, the dielectric constant of which is a function of the electric bias thereacross. If more than one of the plurality of reactive elements is activated, they are preferably chosen in a spatial sequence (Fig. 3, not shown) which produces minimum asymmetry, and hence minimum mode conversion, in the cavity. The cavity may include, in addition, a mechanical tuner.

Abstract: 863,057. Internal shoe-drum brakes. BENDIX CORPORATION. April 6, 1959 [July 10, 1958], No. 11616/59. Addition to 833,729. Class 103 (1). In an improvement of the invention claimed in the parent Specification the adjusting device 28 of the brake is provided with a warning device as to when the brake linings require replacement. This takes the form of a socket member 42 having a hollow cylindrical recess into which screw 38 is free to slide; the latter having screwed thereon a nut 48 which is provided with a hollow cylindrical recess 50 which fits over the exterior surface of socket 42. The difference in diameter between the hollow cylindrical recess 50 and the threaded exterior of the nut 48 is defined by a shoulder 52 which bears against the end of the socket and provides a seat therefore. The warning device takes the form of an unthreaded portion 58 which is of greater diameter than the root diameter of the thread of the nut 48 thereby preventing the screw 38 from advancing through the nut 48 further than the point where portion 58 engages the thread of the nut which makes it impossible for the nut to turn further and extend the screw 38. The nut 48 is provided with a serrated wheel 54 which co-operates with a lever 30 pivoted on secondary shoe 16 and which is engaged during brake application in the reverse direction of the vehicle movement (or clockwise rotation of the drum 12) when secondary shoe leaves the anchor post 24 applying tension to the cable 32 which is transmitted to the lever 30 which is in turn pulled upwardly a sufficient distance to properly engage the adjusting device 28; this action being similar to that disclosed in the parent Specification. Reference has been directed by the Comptroller to Specifications 779,889 and 779,890.
