Abstract: 825,224. Etching; transferring designs. MULLARD RADIO VALVE CO. Ltd July 17, 1957 [July 31, 1956], No. 23603/56. Drawings to Specification. Class 100(2) A method for the manufacture of a printed circuit comprises the steps of cutting out of a sheet apertures corresponding to the circuit outline; mounting the apertured sheet on a backing sheet; placing against the apertured sheet a two-ply tissue comprising a support layer and a resist layer, the former in contact with the apertured sheet, placing a sheet of transfer material against the resist layer; placing the assembly so formed between the plates of a heated platen press; operating the press so that the resist is transferred from the support layer to the transfer sheet except in the circuit outline areas, where the apertures in the apertured sheets prevent the pressure from being applied, removing the assembly from the press, and the tissue from the assembly, the tissue now having a resist covering in the circuit outline areas; placing the tissue with the resist in contact with an electrically conductive surface; applying heat and pressure to the transfer the resist pattern to the conductive surface; removing the tissue support layer and dissolving out the uncovered parts of the conductive surface to leave a resist-coated circuit outline. The apertured sheet may be Bristol board or paper 1/32 inch thick and is secured to the backing sheet by gum. The tissue support layer is cellulose acetate, paper or polyvinyl chloride and the resist celluose paint. The transfer sheet is good quality art paper. The conductive surface may comprise a copper coating metal foil, or metallic grains (e.g. a layer of metallic paint). Alternatively, a suspension of. graphite in a solution of a binder may be deposited on the support and the solvent evaporated, or the conductive material may be a granular material in a synthetic resin binder. The conductive. material may be attached to an insulating support, which may be a synthetic resin.. A printer's blanket may be placed between each plate of the press and the assembly. The unwanted conductive surface may be removed by etching with ferric chloride, or, in the case of conductive material mixed with a binder, with a solvent of the binder. A plurality of apertured sheets may be mounted on one backing sheet. According to the Provisional Specification, the backing sheet may be cardboard and the apertured sheet secured thereto by double-gummed manilla; the insulating support may be the synthetic resin known under the Registered Trade Mark "Bakelite"; and the conductive surface may be a solid sheet of brass, so that the final product is a die which can be used to form printed circuits.

Title: Improvements in or relating to control systems for electric motors
Filed: 1951-10-15
Abstract: 704,700. Control of A.C. motors. IGRANIC ELECTRIC CO., Ltd. Oct. 15, 1951 [Oct. 16, 1950], No. 23968/51. Class 38(3) A hoist motor 10 of the slip-ring induction type has a torque-resisting means 13 (which may be an eddy-current or powder metal clutch) coupled to its shaft, an exciting winding 13a being provided for the torque-resisting means. The motor is controlled by means of a drum 15 which regulates reversing contactors H and L,. and contactors 1A- 1D for varying the rotor resistance 16. The wind ing 13a is energized from supply-lines L2, L3, through transformer PT1, and, combined with the current-component so derived is one dependent upon the current in one of the motor primary phases which is obtained by means of transformer CT. The respective current-components applied to the winding 13a may be arranged to balance at zero speed, and at speeds higher than standstill (including speeds above synchronism) the energization of the coil will be substantially proportional to motor speed. A magnetic amplifier having a tuning resistor R2 may be placed between the rectifier 17 and coil 13a On the first lowering position of the master controller the entire output of the rectifier 17 is supplied to the winding 13a, and, as the controller is advanced in the lowering direction, relays 2L-5L are closed in succession to by-pass progressively increasing amount of the current through the brake coil. The brake may be used during hoisting operation to obtain creeping speeds, but at the higher speed notches contactor 1B closes contacts 18 to render the torque-resisting means ineffective. If the motor has a comparatively low power factor it may be necessary to provide an additional compensating component for the brake coil in order that the resultant speed responsive current supplied thereto may be zero when the motor is at standstill. Such a component can be derived through a transformer having its primary winding connected across supply-lines LI, L3, and its secondary winding connected in series with the secondary winding of the transformer PT1, Fig. 5 (not shown).

Abstract: 708,357. Adhesive tape affixing. COW & GATE, Ltd., and CHARLES, G. K. Sept. 5, 1952 [Oct. 19, 1951], No. 24496/51. Class. 73 An apparatus for applying adhesive tapeto packets comprises a pressure roll 5 mounted on an arm 3 held upright by a spring against a stop 40 and extending. through a slot 2 in a platform 1. Pressuresensitive adhesive tape 35 from a spool 36- passes round a roll 38, a knurled feeding roller 7, and a roll 39 to a pivoted guide plate 9 on which it is held by a spring-urged detent 14 to project in front of the roll 5.. As a package 49 is pushed along the platform 1, it engages the tape and forces the roll 5 backwards its leverage about its pivot 4 always remaining large so that only light pressure by the package is necessary, and since the normal upright position of the lever is forward of its pivot 4, the roll 5 first rises to ensure adhesion of the end of the tape. As the package advances, the guide 9 swings about its pivot 10 to bring the tape 35 into contact with a serrated cutter 19, the feed roller 7 moving away from the tape which is then slack during its application except for the friction of the detent 14. The guide 9 is caused to give a sudden severing movement as the tape 35 contacts the cutter 19 and to remain depressed until the return movement of the lever 3, which is damped by a dash pot. The roll 7 at the same time engages the tape 35 to feed it. Specifications 613,294 and 664,519, are referred to.

Title: Improvements in devices for connecting a load to a parachute
Inventor: DEJEAN LUCIEN GUY
IPC: B64D17/38
Filed: 1951-10-22
Abstract: 695,345. Separable connectors. S O C . NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-OUEST. Oct. 22, 1951 [Oct. 23, 1950], No. 24624/51. Class 44 A device for connecting a load to a parachute comprises, in the form of Fig. 1, a hollow casing 1 having a lower movable rod 4 slidably guided therein and adapted for connection to the load to be carried by the parachute. The rod 4 is normally prevented from leaving the casing by balls 7 retained in engagement with a groove 6 in the rod by the walls of the casing. A spring 8 acting on a washer 9 urges the rod 4 upwardly. Upward movement of the rod 4 is limited by a device comprising an annular member 22 having a rod 21a passing therethrough carrying a spring loaded piston 21 working in an oil-filled bore 20. Balls 28 are retained by the upward pressure of the rod 4 in a groove 31 in which position they engage in a circumferential groove in the rod 21a to prevent the piston rising under the force of its spring 26. When the parachute attached to a falling load opens the rod 40 is drawn down by the tension, this allowing the balls 28 to roll out into the cavity 1b releasing the piston for upward motion. The upward movement of the piston is controlled by the slow passage of the oil through the bore 27. When the piston has reached the uppermost position and the load touches the ground, the rod 4 rises under the action of spring 8 to the position where the balls 7 may escape into the cavity 1b thus freeing the rod 4 to leave the casing and disconnect the load from the parachute. The time taken for the piston to reach its top position ensures that should the tension on the connector become zero, e.g. due to the load springing on the parachute ropes the load is not released. The parts are assembled by first clamping the balls 28 between the member 22 and a washer member 29 by means of a shouldered rod 34 screwing into a threaded bore 33. The rod 4 and casing 1 is then assembled and the rod 34 removed through the bore in rod 4. In the form of Fig. 2 the rod 4 is limited in its upward movement by engagement with balls 52 seating in a conical recess 53 in the end of rod 4. The piston 48 is controlled by air which leaks past it to allow it to rise slowly under the action of spring 49 being normally held by the engagement of the balls in a groove 51 in rod 48a. When the parachute opens the piston is released and rises until the rod 48a passes out of the bore 4a in rod 4 and allows the balls to roll out through the bore 4a. On contact with the ground the rod may then rise to free the balls 7 as before.
