Abstract: 1,231,863. Photographic transfer processes. ITEK CORP. July 25, 1968 [Aug. 4, 1967 (2)]. No.35435/68. Heading G2C. A method of producing dye images comprises imagewise exposing a material containing a freeradical generating organic compound and a dye base to produce a negative dye image and either (i) transferring the dye image to a receptor sheet using a solvent for the dye (e.g. a polar solvent) and if this is solvent for the dye base, removing the dye base with a non-polar solvent before transfer or (ii) transferring the unexposed dye base and organic compound using a solvent for the dye base and compound which is not a solvent for the dye to the receptor sheet and uniformly exposing the receptor sheet to produce a positive dye image. Multi-colour images may be produced on a receptor sheet by using materials containing yellow, cyan and magenta dye bases and repeating the exposure and transfer steps with each material. The material may contain an organic sulphur compound to increase dye density as disclosed in Specification 1,067,150. The preferred dye bases are those specified in Specifications 1, 000, 195, 997, 170 and 959, 037 and the organic compounds specified are organic halogens. Non-polar solvents used are hydrocarbons and polar solvents used are alcohols and ketones. In the Examples, a support is coated with carbon tetrabromide, 2-mercaptobenzothiazole and a magenta dye base in a binder and is imagewise exposed through a green filter to a negative colour transparency to obtain a positive corresponding dye image. The unreacted dye base is removed with a hydrocarbon solvent and the dye image is transferred to a receptor sheet moistened with alcohol. The process is repeated using cyan and yellow dye bases and red andblue filters to produce a multi-coloured positive dye image on the receptor sheet. Such an image may be produced by transferring the unreacted dye base using petrolium ether/ acetose (4:1) and uniformly exposing the receptor sheet; a positive colour transparency being used for the initial exposure. It is also stated that a light-sensitive material containing at least two layers and each layer containing a different dye base may be used in this method.

Abstract: 1,233,363. Improvements in coin operated amusement machines. COIN OPERATED GAMES Ltd. 18 Dec., 1968 [18 Sept., 1967], No. 37909/67. Heading A6D. [Also in Division F2]  A "fruit machine" having a friction clutch device, which is released by a control unit after the drums are rotating, allowing the drums to rotate independent of their shaft 3. The clutch device consists of a spring 13 whose pressure on the pressure plate 12 ensures that the drums 1 with the usual attached toothed wheel 2 on which each depression is associated with a particular symbol on the drum 1, are driven on rotation of the shaft 3 through the contact of the clutch plates 6, which are keyed to the shaft 3 by a spline 7 (not shown), with the friction discs 8 attached to the toothed wheel 2. When the drums 1 are rotating with the shaft' 3, a control unit activates the electromagnets 14, which attracts the pressure plate 12 against the action of the spring 13, resulting in a separation of the clutch plates 6 and friction discs 8, resulting in the drums 1 rotating independently of the shaft 3.  The pressure plate 12 may alternatively be moved mechanically to separate the clutch plates 6 and the friction discs 8 against the action of the spring 13 by the action of a fork actuated by a pivoted lever, which itself is actuated by a cam device rotated by an independent motor or through gearing from the shaft 3.

Abstract: 1,256,579. Polyester fibres. CHEMIEFASERKOMBINAT SCHWARZA " WILHELM PIECK " VEB. 16 Sept., 1969, No. 45544/69. Heading B5B. Polyester and copolyester fibre materials are stretched using a one-stage stretching process wherein the fibre is heated to slightly above its second order transition temperature before stretching, no additional thermal energy being supplied to the stretching zone during stretching, and the fibre material being passed through the stretching zone without touching snubbing pins or heating bars, the stretching ratio being 1: 3 to 1:5.  The process may be carried out with filaments based on polyethylene terephthalate. These are heated on heating rollers to a temperature between 67 and 72‹ C., preferably 70‹ C., then stretched using a ratio of 1: 3 to 1:5. It is preferred in this embodiment that the filaments are'cooled, to remove the heat of stretching from the interior of the filaments while in the stretching zone either directly or indirectly, provided the temperature of the filament does not drop below that needed for stretching, e.g. 70- 75‹ C. When stretching copolyester filaments by this process, the heater rollers can be heated to 67-77‹ C., and the filaments stretched at a preferred draw ratio of 1: 3À81. Filaments so made show high shrinkage, enhanced latent crimp and increased dyestuff take-up. In the examples, polyethylene terephthalate filaments so made show shrinkage values of 20 to 23% and filaments of a copolyester of polyethylene terephthalate modified with isophthalic acid show shrinkage values of 31-32%.

Abstract: 1,267,107. Thermistors. STANDARD TELEPHONES & CABLES Ltd. 19 Nov., 1970 [25 Nov., 1969], No. 57626/69. Heading HlK. A thin film thermistor is formed by first depositing on a clean insulating substrate 1 (Fig. 1) a pair of spaced apart contact pads 2, 3 and an elongate base electrode 5 which contacts one and is spaced from the other pad, then sputtering a thermistor material 6 to cover the electrode except where it abuts its contact pad, and finally depositing by sublimation or evaporation an elongate top electrode 7 which crosses the base electrode and extends to the other contact pad 2. In the example the substrate is of glass or alumina, the low resistance pads 2, 3 of chromium below and gold above, electrode 5 of chromium or manganese below and silver, gold or nickel above, and electrode 7 of pure silver. Layer 6 may be deposited by triode sputtering in argon, possibly containing a trace of hydrogen or oxygen, as described in Specification 1,104,770 using a target consisting of a 5 : 1 Mn 2 O 3  : NiO mixture and is subsequently stabilized by heating in vacuo or air. A protective layer of silicon monoxide is finally deposited to leave only the bonding areas exposed. In an alternative construction the lower electrode is comb-shaped (Fig. 2, not shown) or of serpentine form to allow adjustment of the thermistor resistance by cutting to isolate one or more of the teeth of the comb or limbs of the serpentine. Adjustment may instead be effected by microengraving to eliminate parts of the upper electrode. The contact pads and higher resistance electrodes are deposited in any sequence by evaporation or sputtering through masking so as to overlap at their ends.

Change in attitude of the vehicle is sensed by the torsion bars which rotate thus displacing the cable 14 and its slider 15 longitudinally via the arms 6, 12 and springs 7, 13, this displacement of the slider rotating control shaft 24 via tie rod 21 and changing the headlamp attitude via linkages 27, 28. Rapid changes in vehicle attitude due to road surface irregularities are not transmitted to the control shaft 24 but are absorbed by the springs 7 and 13. A damper 36 is provided linked to the control shaft 24 via spring 32 so that when the vehicle tilts suddenly, as on braking or accelerating, and the lamps are tilted, spring 32 flexes suddenly without moving the damper, so that the lamps are quickly restored to their untilted position by this spring. Slow tilting of the vehicle however, as due to loading, gives time for the damper to operate and the lamps are retained in their tilted position. Two embodiments of the linkages between the control shaft 24 and the headlamps are described, one comprising a simple hinged device as shown, and the other comprising a cam attached to a lever connected to the control shaft co-operating with a roller on a lever connected to the lamps, the cam and roller being retained in contact by a spring, Fig. 2, not shown.
