Title: A method of growing a crystal or a crystalline layer
Inventor: PALMER ANTHONY WILLIAM
IPC: B02C4/02
Filed: 1964-10-08
Abstract: A crystalline rod 14 (Figure not shown) is grown on an anode 10 from a molten zone 15 which is formed as a result of an electric discharge 12 from a cathode 11 of the material of rod 14 or a constituent thereof.  The discharge may be facilitated by preheating the electrodes, e.g. by a winding of nickel chrome wire on a silica tube. Given a constant current supply, a servomechanism may maintain constant the discharge gap by utilizing the relationship between voltage drop and width of gap. The rod may be of nickel, iron, cobalt, titanium, or vanadium oxide; or nickel ferrite.  Nickel and iron oxide may be grown in air at atmospheric pressure using a cathode of the metal.  A nitride is grown when the arc is struck in N2.  A rod of nickel oxide doped with lithium oxide may be produced from a cathode of the same material. A rod 14 of increasing diameter may be formed using a tapered cathode 11.ALSO:A crystalline rod 14 (Fig. not shown) is grown on an anode 10 from a molten zone 15 which is formed as the result of an electric discharge 12 from a cathode 11 of the material of rod 14 or a constituent thereof.

Title: Improvements in or relating to the Control of Power Driven Models by means of a Beam of Light.
Inventor: BURTON PHILIP
IPC: A63H30/00
Filed: 1966-09-16
Abstract: 1,160,438. Toy vehicle controlled by light beams. P. BURTON. 7 Sept., 1967 [16 Sept., 1966], No. 41472/66. Heading A6S. [Also in Division G1] The speed or direction of motion of a model vehicle is controlled by directing a light beam at one or more of three photoelectric elements mounted upon the model, two of the elements having a field of view in one and the same direction relative to the third which has a field of view in a different direction. In Figure 3, which shows a circuit for controlling the direction of motion of a model, photoresistors 18, 19, 20 when illuminated operate relays 24, 25, 26, respectively. Relays 24 and 25 are self latching and when both are operated reverse the d.c. supply to the driving motor to reverse the motion of the model. Relay 26 when operated breaks the holding circuits of relays 24 and 25. The photoresistors are each contained at the closed end of a cylindrical or conical light shield with the opening of the shield of photoresistor 18 pointing in a different direction to the direction of the other two. A general sweep of the beam across the model only therefore illuminates photoresistors 19 and 20. A sweep from right to left stops the car by latching up relay 25; a sweep back again unlatching it to drive the model forward or if photoresistor 18 is illuminated to latch up relav 24 to reverse the model. Phototransistors may be used instead of photoresistors.

After a short time the bimetallic strip 30 breaks the circuit to the glow spiral 18 and the heater 32. The circuit is again energized when the bimetallic strip 30 cools if the cigarette remains in the funnel member 10. The lighter is enclosed within a housing 22 having a hinged cover 11 giving access to the funnel member 10.

The graft copolymer superstrate comprises 20 to 100% by weight of monovinylidene aromatic compound, up to 80% by weight of acrylonitrile, methacrylonitrile and/or a C1-C4 alkyl methacrylate, and up to 20% by weight of acrylic or methacrylic acid, a higher alkyl methacrylate, an alkyl acrylate, a conjugated diene or a dialkyl maleate or fumarate. The graft copolymer substrate consists of a homopolymer of butadiene or isoprene, or copolymers thereof with monovinylidene aromatic compounds, acrylic and methacrylic acids and esters, amides and nitriles thereof and small quantities of polyethylenically unsaturated monomers. The monovinylidene aromatic compounds used in making the graft copolymer and the rigid polymer are selected from styrene, ar-alkylstyrenes, alpha-methylstyrene and ar-halostyrenes. The rigid polymer may comprise comonomers such as those specified in connection with the graft copolymer superstrate.  The Example describes grafting a mixture of acrylonitrile and styrene on to a latex of a butadiene/styrene/divinyl benzene copolymer, blending the product with a latex of a styrene/acrylonitrile copolymer, and coagulating the mixed latices.  The impact strengths of blends prepared with narrow molecular weight distribution styrene/acrylonitrile copolymers are greater than those of blends prepared with wide molecular weight distribution copolymers.
