IPC: H01L29/00
Filed: 1968-11-14
Abstract: 1,252,565. Integrated devices. WESTERN ELECTRIC CO. Inc. 14 Nov., 1968 [15 Nov., 1967], No. 54031/68. Heading H1K. An integrated arrangement comprises a planar transistor with a contact layer bridging the collector-base junction to form a Schottky barrier diode connected in parallel with and poled in the same sense as the junction to prevent saturation of the transistor. In the beam-lead structure shown (with branched base and collector leads 428B, 428C) all contacts to the NPN silicon transistor comprise platinum silicide layers formed by depositing platinum and heating the structure. The silicide 425 makes ohmic contact to the P-type material of the base region 514 and to the low resistivity N-type material of the emitter region 515 and of the contact zone 517 of the collector region but forms a Schottky barrier contact with the high resistivity bulk 411 of the collector region. The three leads 428A, 428B, 428C are built up by the successive deposition on the silicide (after the removal of unreacted platinum) of titanium 526, platinum 527, and gold 428 layers. Schottky barrier contacts may instead be formed using copper silicide, copper, platinum, or tungsten.

Abstract: 1,252,955. Breaking fibrous materials. SPERRY RAND FRANCE S.A. 6 May, 1969 [6 May, 1968], No. 22989/69. Heading D1N. [Also in Division A4] A machine which cuts or breaks fibrous material comprises a rotor having a plurality of flails 10 which pick up the fibrous material, a comb 15 having teeth between which the flails 10 pass when the rotor rotates so that the fibrous material is cut or broken, and guide members 17 disposed adjacent the teeth to guide material located at the ends of the flails 10 inwardly thereof toward the mid-portion of the teeth to inhibit accumulation of fibrous material at the roots of the teeth. The edges of the guide members and the teeth cooperate to enclose the material as the flails enter between the teeth. As shown, the guide members 17 are made integral with the comb which is made of a plurality of channel-shaped members 15. The sides of these channels are notched to form the guide 17 and teeth. The edges of the flails 10 can also be notched (as shown) so as to enclose the fibrous material as they enter between the teeth. The machine can be pulled over the fibrous material by a tractor having a  power take-off to drive the flails 10. The leading edge of the machine 6, 28 can be shaped to compress the fibrous material as it moves forward. The rotor can be raised to an inoperative position by a fluid-actuated cylinder.

Abstract: 1,253,146. Burner controls. SOC "APPAREILLAGE THERMOFLEX ETABS J.M. DARD". 25 Feb., 1969 [24 April, 1968], No. 10136/69. Heading F4T. A burner control circuit comprises a single phase electric motor M, having parallel main and starter windints E 1 , E 2  respectively, for driving fuel feed apparatus, a spark igniter TA, and triacs Al 1 , Al 2  which control energization of the starter winding E 2  and igniter TA and are themselves controlled by the output of a relaxation oscillator comprising a capacitor C 2  and a gatetrigger diode DD 1 . On closure of a thermostatic contact Aq, the motor, igniter and oscillator are energized and a capacitor C 1  in parallel with the oscillator becomes charged via a diode D 1 . When flame occurs, the resistance of a photoresistor DF in parallel with capacitor C 1  and diode D 1  falls so that after a few seconds capacitor C 1  is discharged and the oscillator, igniter, and starter winding are de-energized. Heater windings RS 1  and RS 2  are incorporated in series with the motor windings so that prolonged energization of winding E 2  due to absence of flame, or excessive current through winding E 1 , trip a relay switch RSC and energize an alarm L. A single triac may replace the two devices Al 1 , Al 2 , or each device may be controlled by a separate oscillator.

Abstract: 1289314 Polishing pads MINNESOTA MINING & MFG Co 13 Nov 1969 [14 Nov 1968] 55713/69 Heading A4F [Also in Divisions B2 B5 and C4] Polyester strips, e.g. fibres and films which can readily bond to synthetic resin coatings are produced by immersing a hot amorphous polyester strip in a quench solution of an isocyanate dissolved in and reacted with a stoichiometric excess of at least one liquid monohydric alcohol, rinsing the quenched strip in a liquid which is compatible and miscible with the quench solution to remove excess quench solution from the surface of the solidified fibre or film and tensilizing the quenched and rinsed strip. Tensilizing means stretching in the longitudinal direction at a stretch ratio sufficiently high and at a temperature such that the polyester material of the strip becomes crystalline and oriented, whereby its tensile strength is increased. In an example, filaments produced in accordance with the invention are crimped, out to about 5 cm length, converted into a lofty, open, low density, non-woven fleece about 1À25 cm thick, and slurry comprising 353 parts of 81% thermosetting phenol-fermaldehyde resin, 94 parts of a polyamide resin, 210 parts of ethylene glycol monoethylether, and 754 parts of grade 280-600 aluminium oxide is applied to the fleece. The impregnated fleece is heated to 150C. and then 170C., whereby the phenolformaldehyde resin is cured and the fleece converted into a relatively rigid abrasive and polishing pad. Discs are cut from the treated fleece and tested in conventional floor polishing machines.
