Abstract: 1,165,490. Travelling sign with hinged reflecting surfaces. INTERNATIONAL BUSINESS MACHINES CORP. 10 Sept., 1968 [16 Sept., 1967], No. 42904/68. Heading G5C. Magnetizable elements 2 having a reflecting surface are secured to a travelling web 1 by a resilient bendable member (3), (Fig. 3, not shown) and can be selectively attracted by a magnetizing station 4 from their usually inclined position so as to lie flat against the web, as at 6. There may be an array of magnetizing stations 4; thus a composite sign can be built up. Holding magnets 5 retain elements 6 in their flat position during viewing. If a light source 7 is used, the inclined elements 2 are invisible to an observer 8.

Title: Improvements in or relating to a method of manufacturing filaments
IPC: C03B37/02
Filed: 1967-10-02
Abstract: 1,212,355. Filaments; coating with glass. UNITED AIRCRAFT CORP. 2 Oct., 1967 [17 Oct., 1966], No. 44659/67. Headings C1A and C1M. [Also in Divisions B2, B3 and C7] In a method of manufacturing a filament of metal or metal compound from molten material the molten material is expelled through an orifice in a downwardly directed jet, the jet being electrically charged and being adjacent to, or surrounded by, one or more electrodes which are electrically charged opposite to the charge on the jet to create an electrostatic field. A heat exchange medium is passed into the electrostatic field and the velocity and volume of the medium and the voltage in the electrical charges in the jet and electrodes are correlated to maintain a rate of cooling of the jet between 0À001 to 0-04 calories per second per square centimetre per degree centrigrade. The filament may be produced from molten nickel, chromium stainless steel, beryllium, boron, titanium, aluminium, iron, tin, or of aluminium oxide, aluminium oxide with magnesium oxide and/or silicon dioxide, or aluminium oxide with calcium oxide and silicon dioxide. The filament may be treated to coat it, or form an alloy or compound, by supplying a reactant to the surface of the filament. Examples described include the formation of a molten boron jet which is reacted with graphite particles or methane to produce a boron carbide filament, the formation of a molten titanium (boron) jet which is reacted with boron (titanium) particles to produce a titanium boride filament, the formation of a molten boron jet which is partly reacted with propane/boron trichloride to give a boron carbide-coated boron filament which is subsequently coated with silica from a finely powdered quartz aerosol (Example 3), boron coated with silica or carbon and chromium or nickel coated with a silica powder to form a glass coating. Fig. 1 shows the filament being cooled by a horizontal gas flow of an inert or reactant gas, the filament being retained in position in the gas flow by electrostatic forces created by a voltage across the filament and a metal porous tube from which the gas flows. 'In an alternative embodiment (Fig. 2, not shown), a corona discharge is formed between the filament and surrounding electrodes that causes a cooling convection current in the surrounding gas or air. In a further embodiment (Fig. 3, not shown), a corona discharge is formed and a stream of flux particles are fed into its field and the particles are carried to the surface of the filament and absorb heat therefrom. The particles may be left on to form a coating or may be chemically removed. The flux particles may be added to stop a reaction at a given time. Flux materials used are Al 2 .O 3 , Si.O 2 , Mg.O, Mg.O+Al 2 0 3 , Ca.O +Mg.O, Ca.0+Al 2 0 3 , Na 2 O + Si.0 2 , Mg.O + Si.0 2 , Mg.O+Ti.O 2 , Pb.O + SiO 2  and Al 2 0 3 +SiO 2 .

Abstract: 1,155,469. Steering vehicles. COLORTRAN INDUSTRIES, Inc. 11 Oct., 1966, No. 45290/66. Heading B7H. A steering arrangement is provided for selectively steering the front, rear or all four wheels in a crab-wise fashion of a camera dolly. Each of the front and rear pairs of wheels is steered through a chain and sprocket transmission, the front wheel transmission including a drive sprocket 110 and the rear wheel transmission including a drive sprocket 112, both sprockets 110 and 112 being rotatably mounted on a shaft 82 provided with a slot 128 in which slides clutch device 132, comprising a lever 136 which can engage slots in either or both the sprockets 110 and 112. Shaft 82 is connected to a shaft 40 which may be rotated by a handle 72 for steering the vehicle. A pin 138 extends through the upper part of the member 132 and rests upon an arm 102 of a yoke 98, the yoke being upwardly urged by a spring 108. Pegs 116, 120 are affixed to the upper and lower arms of the yoke and may be brought to register in holes 118, 122 respectively. For changing the modes of steering, the wheels must be aligned longitudinally of the vehicle to -align the holes 120 and 118 with the pegs 120 and 116 and so that the clutch lever 136 may pass from one slot to another in the sprockets. To select steering of the forward wheels, the yoke 98 is allowed to rise to its upper position, as shown, in which clutch lever 136 engages the slot in sprocket 110, so that this sprocket may now be driven by rotation of shaft 82. Sprocket 112, meanwhile, is prevented from rotation by engagement of peg 120 with hole 122. For steering the rear wheels, the yoke 98 is depressed to its lower position for the clutch lever 136 to engage sprocket 112 and peg 116 to engage hole 118 to prevent sprocket 110 from rotating. In an intermediate position, neither peg 116 nor peg 120 engages its respective hole, and clutch lever 136 is partly in each slot in sprockets 110 and 112 so that they may both be driven. A selector knob 42 is located at the top of shaft 40 which is depressed to select the required steering mode, the knob being connected to a rod 150 extending through the shafts 40 and 82 and bearing upon the top of device 132. A pin 154 is connected to knob 42 and may slide in a slot 156, the correct elevation for the three steering modes being determined by the top of the slot and two horizontal portions 162 and 164. The steering mechanism is mounted beneath a platform 28 of the vehicle and the shaft 40 is mounted in bearings in a frame 34 mounted in sockets 68. The connection between shafts 40 and 82 is readily disengageable so that the upper part of the steering mechanism can be removed by removing the frame 34 from the sockets 68.
