Title: Method of transferring a picture from an initial support to a new support
IPC: B44C1/175
Filed: 1968-07-19
Abstract: 1,217,915. Transferring designs. O. R. F. AF STROM. 19 July, 1968, No. 34642/68. Heading B6C. A picture is transferred from an original support to a final support by being affixed to a temporary base, after which the original support is replaced by the final one and the temporary base removed. First a layer of a transparent water-insoluble pressure-sensitive adhesive is applied to the face of the picture by transfer from a backing sheet which is then removed, preferably by separation from the adhesive along a silicone parting layer, then the temporary base is applied, and is held by the adhesive. The temporary base comprises a carrier, an intermediate layer and a layer of lacquer which contacts the adhesive. When the initial support is removed the picture is held by the adhesive to the lacquer. The final support is then substituted, and removal of the carrier and intermediate layer leaves the final support and picture covered by the adhesive and lacquer layers. The intermediate layer may be watersoluble, consisting of starch and gum-arabic for example, and be removed by washing. Alternatively, it may be a thin layer of a silicon.

Title: Improvements in or relating to the manufacture of guanidine nitrate
Filed: 1937-12-15
Abstract: 507,498. Guanidine nitrate. BURNS R., GAY, P. F., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 15, 1937, No. 34755. [Class 2 (iii)] Guanidine nitrate is prepared by the interaction of ammonium nitrate and a cyanamide salt in the presence of a proportion of water not less than 4 per cent, calculated on the weight of ammonium nitrate. Preferably, the proportion of ammonium nitrate to cyanamide salt is more than 3 : 1 mols., the proportion of water is 30-60 per cent (preferably 50 per cent) of the weight of ammonium nitrate, and the reaction temperature is 90-130‹ C. The reaction may be effected by adding sufficient water to the ammonium nitrate to liquefy it at the desired reaction temperature, heating the mixture to that temperature, and adding the cyanamide salt gradually with stirring, the vigour of the reaction being controlled both by the temperature and by the rate of addition of cyanamide salt. The product is extracted with water, and the extract may be freed from calcium by precipitation with ammonium sulphate and carbonate, and concentrated.

Title: Improvements in dynamometers
IPC: G01L3/24
Filed: 1947-12-31
Abstract: 652,104. Dynamometers. MORIONDO, E. Dec. 31, 1947, No. 35432. Convention date, March 17, 1945. Addition to 649,731. [Class 106 (ii)] [Also in Group XXIV] The air-brake dynamometer described in the parent Specification is modified for use as a rotary-transmission dynamometer, giving a direct reading of transmitted horse-power. As shown, a cupshaped member 13, provided with triangular notches 14, is keyed to a shaft 3 which is supported in bearings 5, 6 in a housing 8, and co-operates with a spring-pressed disc 15 having arms carrying rollers 18 which engage the notches 14. The disc 15 is axially slidable along a shaft 1, but is driven by the latter through a long key 16. The shaft 1 is supported at one end by a bearing 11, 12 on the inner end of the shaft 3, and at the other end by a bearing 9, 10 in the housing 8. A number of compression springs 19 in housings 22 urge a ring 20 and thrust bearing 21 into contact with the disc 15. The pressure of the springs can be controlled simultaneously by screws 23 which bear against the housings 22. Each screw has a pinion 24 secured thereto which engages a ring gear 25, the latter being rotatable by an extended screw 23 provided with a head 28. When the shaft 1 is driven by a machine to be tested, the shaft 3 is also driven through the yieldable clutch 13, 15, and the axial yielding movement of the disc 15 is a measure of the torque transmitted by the motor. Means to integrate this torque and the speed of the shaft 1, so that horsepower is indicated, comprises a modified speedometer 34 having a hollow shaft 35 which is driven by an inner slidable shaft 38 arranged to be moved vertically by the axial movement of the disc 15. A wheel 39 on the shaft 38 is driven frictionally by a wheel 53 which is constantly rotated by the shaft 1 through helical gears 42, 43, a shaft 44, and bevel gears 47, 48. The wheel 53 is driven by the gear 48 through a telescopic shaft arrangement, and is urged by a spring into contact with the wheel 39. The shaft 38 is coupled through a sleeve 40 to a link 41 which is hinged to a lever 31, this lever being actuated by the disc 15 through a stirrup 32 and link 33. The Specification as open to inspection under Sect. 91 describes also a yielding shaft coupling (see Group XXIV), wherein the compression springs and housings therefor rotate with the axially slidable clutch member. This subjectmatter does not appear in the Specification as accepted.

A method of, and apparatus for, developing photo-sensitive sheets by applying liquid to the exposed surfaces thereof from a roller Y, in which the initial portions of the sheets are maintained substantially free of developer. A sheet 3 is fed between rollers A, B and guided by fingers F1 to the gap between a conveyer C and the roller Y, the gap and the rollers being adjusted so that the first #" of the leading edge is not wetted. The sheet is then flexed over the roller Y and is wet thereby, fingers F2 picking off the developed sheet from the roller. The sheet then passes between rollers P1, Z on to the heated, thermostatically controlled, conveyer C, which is rotated 5% faster than the feeding rollers, so that tension in the sheet squeezes out liquid from the roller Y. The almost dry print is ironed by a heated roller P4.

Abstract: 366,187. Steering gear for boats. SMITH, S., Dingley Dell, Windlesham Road, Chobham, Surrey. Nov. 27, 1930, No. 35683. [Class 114.] Comprises steering-gear of the cam and rocker type in which the follower engaging the screw-thread or cam grooves 3 on the operating shaft 1 comprises an elongated self-aligning shoe member mounted on and rockable in relation to an arm 6 fixed on the operated shaft 7, the faces of the said shoe member presented towards the thread or groove being profiled to conform thereto. In the construction shown in Figs. 2 and 4, the self-aligning member comprises a pair of shoes 8 axially slidable on the head 9 of a T-piece having a stem 10 rotatable in the arm 6. The shoes 8 are shaped at 12, 13 to fit into the cam groove and are kept in place on the head 9 by spring rings 16. The arm 6 or the shaft 7 reacts against the cover 19 of the gear housing 4. In a modification wear is taken up automatically by means of a compression spring which bears against the cover 19 and against the head of the arm 6, this keeping the shoes in tight engagement with the groove and also tending to prevent wheel wobble by damping the movements of the parts. In this modification the stem 10 of the T-piece is tapered and fits into a corresponding hole in the arm 6. In the construction shown in Fig. 6, the follower member comprises a shoe 28 formed with its sides converging so as to co-operate with the converging sides of the groove, this shoe being pivoted on a spindle 30 carried by the T-piece 29.

Abstract: 1,007,644. Distributers. HOLLANDSE SIGNAALAPPARATEN N.V. Oct. 4, 1961 [Oct. 4, 1960], No. 35796/60. Divided out of 1,007,643. Drawings to Specification. Heading H4P. [Also in Division G4] The invention provides a distributer system in which the pulses are generated by a continuously operating pulse generator which supplies pulses in cyclic order to the output circuits, it being so arranged that, upon the reception of a start signal, the system always gives a pulse of full length at the first output and, upon reception of a stop pulse, the system completes its cycle independently of the time of occurrence of the stop signal. In a modification, several such systems, each having a different pulse repetition frequency, are so combined that only one system can operate at a time. In a further modification the start signal for one of the systems may act as a stop signal for the other systems, or the start signal for one system may have no effect upon another system if this system also has a start signal on it. The system is described with reference to a data display system in which the several distributer systems provide synchronizing pulses of various repetition frequencies for controlling magnetic stores, triggers, etc. The display system comprises a system for the simultaneous step-by-step setting of a number of movable elements, there being means for indicating whether or not each element is in its correct or desired position thereby to determine whether or not to step the element further. The display system is described in Specification 1,007,643.
