Abstract: 1,233,241. Gas turbine engine ignition arrangements. McGRAW-EDISON CO. May 24, 1968 [May 29, 1967] No.25066/68. Heading F1G. [Also in Division F4] An electric current flowing between electrodes 23 and the casing 11 of a gas turbine engine, and formed by ions in the gases produced by the engine, provides a signal indicating the presence of flame in a combustion chamber 14. The signal is amplified by an amplifier 25 and holds a relay 26 open, thus de-energizing an ignition system including spark ignition 35 in the combustion chamber. On flame failure, the relay 26 shuts and energizes the ignition system. The electrodes 23 may be situated upstream or downstream of an after burner 18, or in the combustion chamber 14.

Abstract: 1,266,197. Titania pigment. BRITISH TITAN Ltd. 8 April, 1970 [18 April, 1969], No. 19914/69. Heading C1N. A titanium dioxide pigment has trimethylolethane on the surface of its particles. The amount of trimethylolethane may be up to 50% by weight of the pigment, but the preferred amount is from 0À02 to 5% by weight. In a preferred embodiment the titanium dioxide particles have in addition a coating of at least one oxide or hydrous oxide of Al, Ti, Zr, Ce or Si or a phosphate. The amount of such oxide or hydrous oxide may be from 0À5 to 10% by weight expressed as the oxide on the weight of TiO 2 . The coated titania may be prepared by mixing titania with trimethylolethane and heating the mixture to effect distribution of the trimethylolethane over the TiO 2  particles. The mixing may be done in a fluid energy mill to which the trimethylolethane may be added either before or during milling. If desired the trimethyl - olethane may be dissolved in a solvent and mixed with a dispersion of the titania in a liquid, the mixture then being milled and/or dried. Water is specified as a preferred solvent for the trimethylolethane the titania being used as an aqueous slurry. If desired the trimethylolethane may be added as a solid to the TiO 2 . It is preferred that the titania be coated with at least one hydrous oxide of Al, Ti, Zr, Ce or Si or an insoluble phosphate before being treated with trimethylolethane. The titania used may be prepared by the vapour phase oxidation of a titanium tetrahalide. The TiO 2  may be coated in a dry state with Al 2 O3, TiO 2 , CeO 2 , ZrO 2  or SiO 2  by oxidizing an oxidizable compound of Al, Ti, Cl, Zr, or Si on the vapour phase in the presence of TiO 2  particles.

[Also in Division A4] A swivelling castor comprises a wheel fork 2, having a cylindrical upper end provided with a flange 3 extending part way round the circumference, inserted, while the fork is tilted, through an opening in the undersurface of a bearing box 1, and supported by a continuous ring of bearing balls 6 which are disposed in groups at two levels and, on swivelling of the fork, move from one group to the other along channels formed by bevelling the ends of the flange at 9. Ball races are formed on the undersurface of the flange 3 and at 5 on the bearing box for the lower group of balls, and compressed at 4 on the unflanged part of the upper end of the fork and on the bearing box at 7, for the upper group of boxes. A snap catch 10 releasably locks the fork in the bearing box 1 which has a collar 8 to receive a mounting pin or tubular leg. In modifications an upwardly directed collar or edge flanges are provided on the bearing box for insertion in a bore or in slots in a mounting plate or container bottom, or a bearing plate welded to the upper end of the fork has upper and lower semi-circular flanges formed with edge parts of arcuate cross-section to provide parts of the upper and lower face races, respectively, which are connected by diametrically opposed channels in the mounting plate for passage of the balls. In a further modification the upper end of a straight oblique fork, received in a frusto-conical bearing box, has two flanges of unequal length, the upper group of balls being above the flanges and the lower group of balls between the ends of the flanges and the channels for passage of the balls at the ends of the flanges being located at the axis about which the castor tends to tilt in use, spacing balls, smaller than the bearing balls, being inserted through a U-shape recess in the upper edge of the fork to reduce the spacing between the balls.

Preferably a five-layer thermoplastic laminate is formed by applying a two-layer laminate to both faces of a core plastics sheet; such a laminate is preferably made by co-extruding the sheets from molten blends of polymer with the required additives, but may also be made by hot-pressing individual sheets which have been formed by melt extrusion, slot extrusion or calendering. In examples, the core layer is of vinylidene chloride-vinyl chloride copolymer, the interior adhesive layers are of ethylene-vinyl acetate copolymer, the external layers are of polyethylene, and the slip additive is erucylamide, stearamide, oleamide, or 12-hydroxystearic acid.

Abstract: 1295044 Seat slides COX OF WATFORD Ltd 19 Nov 1969 [22 Nov 1968] 55477/68 Heading A4J [Also in Division F2] A slide for a vehicle seat has two slidable channel shaped members 11,12 between opposing surfaces of which are balls or rollers 14 which carry load during movement of the slides, the arrangement being such that one of the channel members may deform under load so that load may be transmitted between the members either only through the balls or rollers when the arrangement is under a certain load, or through contacting surfaces 45, 46 of the members when under a higher load. The arrangement may also be such, that there is contact between other surfaces of the channels at loads lower than that at which there is contact only through the rolling elements. Plastics interlayers (16,17) Figs.4 and 5 (not shown) may be provided between the members to facilitate sliding when the members are in contact. The members are provided with fixing means at portions out of contact with the balls or rollers. The channel members may be provided with stops (21)Fig.2(not shown) which cooperate with balls or rollers to limit the movement of the members. In addition a latch may be pivoted on a pin fixed to one wall of a member for engagement with a series of notches in the other channel for locking the members in a chosen position. In use one member is secured to the vehicle seat and one to the floor. The arrangement is such that the weight of the occupant deforms the member so that contact is through the rolling elements only, thereby facilitating adjustment of the slide when the seat is occupied, and also that under high loads occurring e.g. during a collision, the load is not borne solely by the balls or rollers.

Abstract: 1328531 PUT pulse generator circuits AMF Inc 19 Jan 1971 [27 Jan 1970] 3845/70 Heading H3T A pulse generator includes a first resistor R1 connected in series with a diode D1 across supply terminals 1, 2, a capacitor C1 connected between the anode of a programmable unijunction transistor PUT and the junction of R1 and D1, a second resistor R2 connected between the anode of the PUT and one of a pair of load output terminals, third and fourth resistors R3, R4 the gate of the PUT being connected to the junction of R3 and R4 and a transistor VT1 having its base connected to the cathode of the PUT, its emitter connected to the supply and its collector connected to the one output terminal thereby providing an output pulse train of predetermined period and mark/space ratio. Capacitor C1 charges via relay RL1, resistor R2 and diode D1 until the voltage at the anode A of the PUT is sufficient to turn the PUT on. Transistor VT1 now conducts and the capacitor C1 starts to discharge via resistor R1, the PUT and the base-emitter path of transistor VT1. Diode D1 is made non-conductive due to the drop in potential at the negative side of the capacitor C1. When the voltage across the capacitor C1 has fallen to a certain value diode D1 conducts again and shunts current from C1 and the PUT so that the PUT and the transistor VT1 turn off. The cycle then restarts with the capacitor C1 recharging. In a cycling time delay relay having variable on/off times (Fig. 2, not shown) a transistor (VT2) is added between the capacitor C1 and the anode of the PUT to provide amplification for the discharge current and enabling longer times by increasing the value of R1. An audio generator may be obtained by replacing relay RL1 by a loud speaker (L, Fig. 3, not shown). The period can be adjusted by changing the values of C1, R1 and R2 and the mark/space ratio is dependent on the values of R1, R2. The voltage required across C1 to trigger the PUT is set by the voltage applied to the anode gate G from resistor divider R3, R4 and stability of the timing V supply voltage and temperature characteristics is obtained.
