Title: A bonded boride composite material
Inventor: JACKSON JOHN STEPHEN
IPC: C22C32/00
Filed: 1953-01-23
Abstract: A heat resisting and electrically conductive composite material is formed of a shaped body of a powdered boride of at least one of the metals Zr, V, Cr, and W infiltrated with a bonding metal of Co, Fe, Ni or Cr, the infiltration being effected either by applying bonding metal powder to the shaped boride body and then heating to melt the bonding metal, or by sintering the shaped boride body and then heating it in contact with molten bonding metal.  The amount of bonding metal may be 3-10 per cent by volume of the boride but where lower electrical resistivity is required, e.g. for the contact of an electrical circuit breaker or resistance welding electrode, the bonding metal should be 25-35 per cent by volume of the boride. According to the Provisional Specifications the metal borides may include titanium boride and according to the First Provisional Specification the composite material may be formed from a powdered mixture of the metal boride(s) and bonding metal which is pressed and then sintered or pressed and sintered simultaneously.  In the latter case the heating may be by high frequency induction or by passage of electric current.

IPC: G11C13/04
Filed: 1969-01-14
Abstract: 1,190,184. Read-only stores. INTERNATIONAL BUSINESS MACHINES CORP. 14 Jan., 1969 [15 Jan., 1968], No. 2043/69. Heading G4A. A data processing system includes an optical memory plane storing a matrix of blocks of bits, and a plurality (e.g. three or two) of matrices of lenses, arranged in series to pass light from an illuminated block, the product of the numbers of lenses in the matrices equalling the number of blocks. The required block of bits, stored in transparent/opaque form, is illuminated with linearly-polarized laser light through a digital light deflector, the matrices of lenses passing the transmitted light to an optical AND gate at which each " transparent " bit of the word to be read out changes the polarization of light from a digital light deflector used to select the word so that the light will pass through a lens array and analyser to an array of photodetectors. A bit can be recorded on the memory plane by passing light, positioned by a digital light deflector, in the reverse direction through the lens matrices, each of which has an associated matrix of electro-optic switches and analyser to direct the bit to only one block, diffusing screens and an automatic photographic emulsion developing system being also provided (in situ). The memory plane could alternatively be a Lippmann film in which case read-out is by reflection using laser light of a frequency selected by an electro-optic frequency selector and positioned by a digital light deflector, or the plane could be metal reflecting spots on glass.

Title: Method of and apparatus for feeding sheets
IPC: B65H5/08
Filed: 1937-01-25
Abstract: 474,122. Feeding sheets. BELLUCHE, E. W., and BELLUCHE, F. R. Jan. 25, 1937, No. 2154. [Class 100 (i)] In mechanism for feeding sheets to printing and like machines in an overlapping stream, the sheets are advanced at a rapid speed for a portion of a predetermined distance, and then at a slow speed for a successive portion of the distance, and the trailing edge of the slow sheet is deflected or lifted to permit the succeeding sheet moving at a high speed to be overlapped by the slow sheet. The sheets, Fig. 1, are advanced from a vertical pile 8 by an oscillating suction device 22 to a high speed roller 23 with which a drop roller 24 co-operates, and the sheets pass under a calipering-device 26, 27, and are led to grippers 18 on a chain 11 which is driven at the same speed as the roller 23. The grippers are opened by cams 19, 20 to receive a sheet and to release the same, but before a sheet is released the preceding sheet is slowed down by means of a number of suction feed-rollers 30 driven at a slow speed. The rollers 30 are mounted between pivoted arms 31 and are raised into contact with the underside of a sheet by means of a bar carried by parallel links 45, 44, operated by a link 48 from a lever 49 and cam 47. The trailing edge of the sloweddown sheet is raised by deflectors 53 attached to the grippers 17, 18, and the fast-moving sheet moves under the raised edge, so that finally a stream of overlapping sheets is fed by drop rollers 52, 51 and a conveyer 50 to the front stops 6 of an impression cylinder 5. In the modification shown in Fig. 7, the parts 30, 53, Fig. 1, are dispensed with and the sheets pass from a fast moving conveyer 55 to an adjacent slow moving conveyer, and before a sheet leaves the conveyer 55 completely, its rear edge is raised by fingers 57 on a rotating shaft 58, thus permitting the subsequent sheet to move under the rear edge of the preceding sheet, the front edge of which is controlled by the slow conveyer. In another modification, the chain 11, Fig. 1, and means for supplying sheets from a vertical pile are replaced by a chain arranged with a vertical and a horizontal run to carry sheets from the fanned-out pile of a continuous feeder.

Abstract: 949,541. Time switches. CONTROLS CO. OF AMERICA. Jan. 21, 1960 [March 16, 1959], No. 2180/60. Headings H2A and H2B. [Also in Division D1] A switch unit for an electrical sequence timer is operated normally at one speed but is advanced to a selected point at the end of its cycle at a higher speed during which time the control circuits are de-energized. The unit comprises a bank of cam-operated switches 46 driven by an arbor 32 rotated normally by a motor 10 driving a cam 12 imparting oscillatory motion to a pawl 24, 28 driving a ratchet wheel 26. The arbor is driven at high speed by a shaded pole motor 48 having an axially movable shaft carrying a peg on a spring 58 engageable with cut-out portion on a pinion 60 which alternatively drives the arbor through gearing and another ratchet wheel 84. The stopping position of the ratchet 84 is determined by a switch 55 co-operating with a cam 68 and a selector switch mounted underneath the ratchet wheel 84, the stopping position being selected manually by switches, Fig. 11 (not shown). On deenergization of the motor 48 the peg disengages with the pinion, thus halting the drive immediately, the rotor kinetic energy dissipating itself in friction. A switch 52, 54, 56 completes a self-holding circuit to the motor, which switch also disconnects another motor providing a slower speed drive. Specifications 949,547 and 949,550 are referred to.

Abstract: 414,068. Preventing inductive disturbance. SIEMENS - SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin.-(Assignees of Siemens & Halske Akt.-Ges.; Siemensstadt, Berlin.) Jan. 23, 1933, No. 2193. Convention date, Jan. 22, 1932. Addition to 364,008. [Class 40 (iv).] In a submarine cable system in which, as described in the parent Specification, four wire working is employed over cables of high attenuation and separate cables are used over at least a considerable part of the distance for the two directions of speech, if one of the cables breaks, two-way communication is made possible over the other by designing the cables initially so that the near-end cross-talk attenuation between some or all of the conductors is greater by more than 4À5 nepers than the line attenuation. This may be done by balancing line inequalities or by screening. For example the conductors may be screened over the whole or part of their length in pairs, quads or layers. In the first arrangement 2-wire working is possible, in the others 4-wire working is employed, a particular screened group carrying conversations in only one direction. In all cases carrier telephony may be carried simultaneously by the telephone circuits and some circuits may be used for multiplex tone frequency telegraphy.
