Patent GB-1271293-A (GB)
Title: Method and apparatus for making fibres
Inventor: GLASS JOHN P
IPC: C30B25/00
Filed: 1969-04-01
Abstract: 1,271,293. Growing whiskers from vapour phase. J. P. GLASS. 1 April, 1969, No. 28796/ 71. Divided out of 1,271,291. Heading B1F. [Also in Division C1] Whiskers, e.g. of aluminium oxide, graphite, boron and sapphire, are grown in a precipitation zone by producing a vapour mixture containing the whisker forming material, supplying this vapour to the precipitation zone and introducing free electrons as crystallising nuclei into the vapour mixture in the zone to induce the formation of whiskers. The mixture components may be introduced into a mixing chamber 112 within a chamber 111, issuing from the bottom of the mixing chamber into a precipitating zone within cylindrical duct 113 the whiskers forming and falling into collector 138. The necessary electrons may be emitted from particles e.g. of BaO, SiO, CaO or the corresponding carbonates, introduced into the whisker forming vapour from container 126. Alternatively precipitation zone may be irradiated by the beam from a radio-cobalt gun 137 positioned below the duct. The thermal conditions within zone, adjusted for example by heating coil 115, may be such that through thermal excitation, or with the aid of the positive charge induced on the vapour particles by the electrons, the whiskers themselves emit electrons and become positively charged with respect to the vapour. Within the precipitation zone a charge may build up repeatedly on the tips of the growing whiskers and be discharged by the deposition of vapour particles. Crystallisation of whiskers may be encouraged by electrostatically charging the precipitation zone by emitting an electrical discharge from a point e.g. 143, in the zone to form a space charge.

Title: Regulating device for electromagnetically driven vibratory pendulums
IPC: H02M7/62
Filed: 1945-10-30
Abstract: 639,985. Automatic control systems for vibratory pendulums. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 30, 1945, No. 28806. Convention date, Nov. 18, 1944. [Classes 38 (ii) and 38 (iv)] Voltage ; amplitude control.-A vibratory pendulum P (Fig. 1) is driven by an electro magnet M which is alternately energizec and de-energized through a contact b operated by the pen dulum at one end of its swing, from a condenser c steadily charged from a variable voltage D.C. source E through, a resistance R. The condenser is periodically discharged through a resistance R1 by a contact k operated by the pendulum at the other end of its swing, so that the charge depends on the impulse ratio of contact k. Voltage variations across c vary the amplitude of the pendulum and the impulse ratio of the contact k so that the voltage energizing the electromagnet, and the vibrational amplitude, are regulated to a constant value. In modifications (Figs. 2, 3, not shown) the impulse ratio similarly controls the charging of the condenser, and the apparatus of Fig. 1 is applied to a self-rectifying vibratory converter. The Specification as open to inspection under Sect. 91 comprises also an electromagneticallydriven vibratory pendulum wherein the drive voltage is controlled by a regulating device (e.g. a carbon pile or motor variable resistance) adjustable by the mean current through a contact operated by the pendulum. This subject-matter does not appear in the Specification as accepted.

Title: Data shifting network for data processing apparatus
IPC: G06F15/80
Filed: 1971-06-18
Abstract: 1354563 Data processing; shifting network SANDERS ASSOCIATES Inc 18 June 1971 [18 June 1970] 28807/71 Headings G4A and G4C  A digital data shifting network shifts data in positional increments of powers of 2, e.g. if data is to be shifted by nineteen positions it is shifted by 2<SP>4</SP>(16) positions in one clock cycle, 2<SP>1</SP>(2) positions in a second clock cycle and by 2(1) position in a third clock cycle. Data is entered in a N bit register 18A (e.g. 1024 bits) having N corresponding skew networks (described in detail, Fig. 3, not shown). Each skew network is connected to each register position a power of two away from it by Y leads, e.g. SN1 is connected to L2, L3, L5, L9, L17, L33 &c. The desired shaft is received from an instruction and the most significant bit of the shift causes one of the Y leads to be enabled thus causing the first and largest shift. The shifted data passes through unit 17 back to register 18A and the next most significant shift bit enables another of the Y leads. This continues until the desired shift is completed. The network is used in a parallel vertical processor (Fig. 1, not shown).

Abstract: 315,154. O'Neill, F. Oct. 10, 1928. Charges, agitating. - A machine for gathering charges of molten glass by suction, and for forming the charges into hollow articles by blowing, has a fore-hearth supplied with molten glass from a tank furnace, and a device which circulates the glass in the forehearth sd that a part of its surface, from which charges are gathered by the parison moulds, is constantly renewed. The tank furnace 23, Figs. 1 and 9, has a forehearth 24 with a removable roof 25 having an opening 26 through which the glass is exposed, the opening being curved to conform with the path of the parison moulds 28. The device for circulating the glass consists of submerged fins 52 radiating from a dome-like member 51 secured to a vertical shaft 47 which passes through an island 48 of refractory material and is rotated by a motor 30. The rotation of the shaft causes the fins 52 to circulate the glass around the island 48 thus always presenting fresh hot glass to be gathered, and chilled threads of glass, which are cut off after a gather has been made, are carried back into the tank. In a modification, the member 51 is carried by a shaft which passes downwards through the cover of the forehearth. An electric heating element may also be arranged along the edge of the opening in the forehearth in order to assist in maintaining the temperature of the glass.

An immersion liquid heating unit has a thermostat for maintaining the liquid temperature at a desired value, the thermostat including suction-operated regulating means maintaining the liquid temperature, in which the suction is provided by motion impressed on the liquid. A liquid heater 14 is controlled by a microswitch 16 operated by a bellows 39 through a weighted lever 44. An impeller 34 continuously driven by the electric motor 32 connected to the heater supply 15 draws liquid through the tubes 36, 35 whereby a suction is produced via 37 in the bellows to lift the lever and allow the micro-switch to close. The tube 35 is connected by a flexible tube 28 to a nozzle 26 on an arm 24 adjustably rotatable by the knob 19a. A flapper 27 normally closes the orifice 26. When the liquid reaches a desired temperature indicated by the pointer 20, the bi-metal 17 rotates a rod 19 and arm 30 to lift the flapper off the nozzle whereby the suction in the bellows is destroyed and the weighted lever opens the micro-switch. In a modification, the bellows 39 is connected via a valve to the tube 37, the valve being operated by another bellows connected to the tube 28 and allowing air to flow slowly into the bellows 39.
