Filed: 1975-04-22
Abstract: 1476886 Printed circuit wafer assemblies TRW Inc 22 April 1975 [22 April 1974] 16545/75 Heading H1R A ceramic substrate wafer 10 of, e.g. fused alumina or sapphire having high dielectric constant is formed with chamfered corners 15 and a metallic coating covering the rear face completely for common ground to a structural housing 75. The front face is selectively coated with metal in a linear pattern 20 separated by non-conductive areas 25 on which circuit elements, e.g. resistor and capacitor chips 35 and enclosed transistors and diodes 45 are mounted in defined locations. Through holes 30 are engraved, e.g. by silicon carbide air blasting and internally plated to provide ground connections. The metallic layers may be of sputtered nickel-chromium alloy, followed by sputtered gold. The front face is then covered with dry process photoresist sheet, on which the conductor line pattern is optically processed, after which the exposed photoresist is developed and dissolved off. Thereafter copper is electroplated on to the exposed portion of the wafer, gold is electroplated on the copper, the photoresist is dissolved off, and the initial metallization is etched off with, e.g. aqua regia to expose the non-conductive areas 25. Then the circuit board is dipped in lead-tin solder to dissolve off the gold and provide surfaces for attachment of circuit elements 35, 40, 45 by their leads and supporting metal frame 50, which has coefficient of expansion similar to that of the ceramic wafer, and extends over the chamfered corners 15 so that it may be mounted to housing 75 by screws 55 in holes 60. The frame is prepared for attachment by flash electroplating nickel followed by copper and gold, mashed on the reverse side, and solder dipped to tin the side to which the wafer is to be soldered by infra-red heating, together with the positioned circuit elements having their leads contacting appropriate parts of the conductive network. Flexible wires may be soldered to the network for external connections. The wafer may be bonded to the frame with epoxy resin in the separate ground connections and components may be mounted on both sides.

Abstract: 958,305. Power factor improvement. GENERAL ELECTRIC CO. Ltd. May 1, 1963 [May 1,1962], No. 16627/62. Heading H2H. In a power factor improvement arrangement having a plurality of successively connectible capacitor banks each arrangeable in star or delta formation, the banks may be connected in series delta or parallel star by a switch 15, Fig. 2, to give a 3: 4 change in capacitive effect. The banks may be changed simultaneously or successively into the star connection, but only after at least two of the banks are connected to the circuit. The banks 7 are each connected through isolators individually to a transductor 6, Fig. 1, to form a quasi-resonant circuit on a subsidiary bus-bar 4 before being connected to the main bus-bar 1. The transductor control windings 11 are supplied from a grid-controlled rectifier 12 supplied from a grid control unit 13. The capacitor bank switching is accomplished by two relays, one 17 sensitive to transductor current and the other 18 sensitive to both transductor current and a dummy load current proportional to capacitor current set to operate when the transductor current equals or exceeds the current of one bank 7. The dummy load circuit is supplied from a potential transformer 20 and incorporates a voltage sensitive relay 21 which drops out at a low voltage and effects star connection if all the banks are connected and a further voltage sensitive relay 22 which operates at emergency low voltages to connect the maximum capacitive reactance to the supply circuit. Interlocks and time delays (not shown) ensure that none of the isolators or switches are operated in an unsuitable currentbreaking condition. Damping filter reactors 10 may be provided in the circuit. In another arrangement (not shown), the subsidiary busbar is omitted. Specification 958,304 is referred to.

Filed: 1928-06-12
Abstract: 319,227. Baker Perkins, Ltd., Baker, G. R., Dumbleton, C., and Paterson, J. C. June 12, 1928. Discharging devices for endless-belt conveyers. - Biscuits or like articles are removed from a conveyer by a suction device which raises them and causes them to adhere to a travelling band which is arranged to pass out of the zone of suction to effect the delivery of the articles by gravity. The invention is described as applied to the discharge of biscuits from an oven conveyer 14 which extends immediately beneath a suction nozzle 15 over the perforated lower wall 16 of which passes a perforated flexible band 10 mounted on rollers 11, 12, 13. The biscuits are lifted from the conveyer 14 by the suction, the band 10 holding them until they have passed the outer edge of the nozzle plate 16 when they drop by gravity on to a conveyer 17 which delivers them to a stacking device. The conveyed 17 passes at its ends over adjustable knife-edges .21, 22 and is driven by the roller 18 which is connected through gearing 24, 25. 26 to the driving wheel 27 of the oven conveyer 14. The band 10 is also driven from the wheel 27 through gearing 28, 29, 30, the sprocket 30 being adjustably mounted in the curved slot 32. The conveyer 17 delivers the biscuits to a device for arranging them in overlapping relationship which comprises overlapping conveyers 34, 41, 46 provided with tensionadjusting means 39, 40, 45, 49 and driven at progressively slower speeds through reduction gearing from a motor 51. To maintain the biscuits in alignment in the various rows, parallel slats 67, 70, 71, are mounted immediately above the conveyers 34, 41, 46, the slats 67 being tapered towards the receiving end of the conveyer 34 which is mounted on a pivoted table 35 so that its height may be adjusted. In the modification shown in Fig. 7, the discharging and stacking devices are combined in a single portable unit mounted on a wheeled frame 92. This figure also shows the application to the discharge of biscuits from trays which are removed from the oven when the baking is completed, the trays being carried beneath the suction nozzle 15 by a conveyer 73 which delivers the empty trays to a transversely disposed roller-way conveyer 74 down which they pass by gravity to a discharge station. The suction band 10, receiving conveyer 17, stacking conveyers 34, 41, 46, and the tray conveyer 73 are all driven from the motor 51 mounted on the framework 92. Specification 247,504, [Class 28 (i), Bread-making &c.], is referred to.

Title: An improved process for the production of artificial resins
IPC: C08G83/00
Filed: 1921-06-22
Abstract: Artificial resins are obtained by subjecting phenol, or its homologues or mixtures thereof, to moderate oxidation by means of potassium ferricyanide, lead oxide in glacial acetic acid, or ferric chloride.  By the action of alkalis, acids, or heat the brown products so obtained are rendered soluble in alkali or are further polymerized; by reduction, colourless products are obtained which are rendered insoluble in alkalis by alkylation or acidylation. According to examples:-the product obtained by oxidizing o-cresol with potassium ferricyanide in alkaline solution is reduced with zinc dust and glacial acetic acid and reprecipitated by water; by partial reduction it may be separated into fractions of higher and lower melting points.  The crude resin is also rendered insoluble in alkalies by heating in vacuo for 2-3 hours at 200 DEG  C., or is, either before or after reduction with zinc dust and acetic acid or hydrosulphite and caustic soda, heated with acetic anhydride and sodium acetate.  The products are soluble in benzene, ether, &c. to viscous colloidal solutions. Specifications 108,938 and 149,979 are referred to.

Abstract: 1302101 Brightening textiles CIBA-GEIGY AG 10 April 1970 [11 April 1969] 17230/70 Heading DIP In a process for the non-aqueous optical brightening of organic fibre material, the material is impregnated with a solution of at least one optical brightener salt consisting of (a) an anionic radical of an anionic optical brightener and (b) at least one organic nitrogen compound containing at least one N-atom capable of salt formation, in a solvent consisting of one or more unsubstituted or halogenated hydrocarbons with a B.Pt. of 50-150C, alone or in admixture with a water soluble organic solvent boiling below 220C; the bulk of the excess solvent is removed from the material, and the brightening is finished by a heat treatment below the softening point of the fibre material. The solvent mixture preferably consists of 80-99% by weight of hydrocarbon and 20-1 % by weight of water soluble organic solvent. The production of the optical brightener salts can be performed in the solvent or solvent mixture, but preferably they are previously prepared, e.g. by double reaction of the alkali metal or ammonium salts of the optical brightener with a salt of an above mentioned organic nitrogen compound with a strong acid, e.g. hydrochloric, or alternatively by direct neutralisation of the anionic optical brightener as the free acid with the organic nitrogen compounds. The impregnating of the fibre material is carried out by coating, spraying or especially by padding. Fibre materials which may be treated are: cellulose 2¢ and triacetate, polyethylene glycol terephthalate, polyurethane, polymeric and copolymeric acrylo- and methacrylonitrile, polyethylene and polypropylene, cotton, viscose, wool and Polyamide 6 or 66. The fibre material is continuously passed through the brightening liquor, containing 0.01-10% by weight of optical brightener at room temperature and then squeezed out until it contains 30-150% by weight of the impregnating solution, relative to the dry weight of the material. The impregnated fibre material is then treated at 70-220C, optionally after preliminary drying in a hot air stream at 40-80C. Preferably the finishing is carried out with saturated steam between 95-105C.
