Title: Spray coating
IPC: B01J8/46
Filed: 1961-05-25
Abstract: Spray coating apparatus comprises a supply vessel for particulate material communicating at its lower end with a downwards leading feed pipe the lower end of which is close to and faces <PICT:0929324/III/1> the upper surface of a conveyer and provided at its lower end with a recess providing an enlarged gap between the feed pipe and the conveyer substantially normal to the line of movement of a point of the conveyer passing immediately underneath the said gap and facing in the direction of movement, and a carrying-away pipe so related to the conveyer as to continuously carry away the particulate material as it is transported by the conveyer from the gap towards the carrying-away pipe as soon as a positive pressure is set up across the carrying-away pipe.  As shown the conveyer consists of a disc 10 (Fig. 1) rotated by an electric motor 11. Particulate coating material 2 in a container 1 is maintained in a state of aeration by air admitted via a valve 30 and passes to the conveyer disc by way of pipe 6.  The disc 10 has a peripheral groove 21 (Fig. 3) into which dips the end of the carrying-away pipe 27.  In operation a gate 14 at the bottom of pipe 6 is adjusted so as to set the gap 13 so as to provide the desired quantity of thermoplastic powder.  The powder is carried away as a ribbon on the surface of the disc from the pipe 6 to the wiper 23 which sweeps it into the channel 21.  The pipe 27 is connected to the spraying head which may incorporate a Venturi jet so as to produce a vacuum in the Pipe 27, or alternatively the whole apparatus may be operated at a pressure greater than atmospheric the top of the vessel 1 being closed so that the particulate material is forced under pressure to the spraying head. Specifications 912,464 and 921,108 are referred to.

Title: Improvements in engine starter drives
IPC: F02N15/00
Filed: 1954-06-29
Abstract: 750,674. Turning-gear. BOSCH GES., R. June 29, 1954 [July 4, 1953], No. 18965/54. Class 7(5) Arrangement In a starter drive having a sleeve 19 that is both connected by a free wheel clutch 20 to the pinion 16 and threaded on a driving shaft 12, the pinion and associated parts being automatically advanced into driving engagement with the engine gear 22 when it is retarded relatively to the rotation of the driving shaft by a brake comprising friction discs 24, 26 and 27, the braking action is automatically reduced to a given value, but not completely removed, when the pinion and associated parts have been advanced past a predetermined position relative to the driving shaft. Three annular brake discs 24 on bolts 25 are loaded by springs 32 intc frictional engagement with the two further discs 26, 27 that are splined to the sleeve 19, the inner diameter of the disc 27 being greater than the diameter of a collar 30 on the extremity of the sleeve. Operation Upon rotation of the shaft 12 the brake 24-27 prevents turning of the sleeve 19 so that the latter is threaded leftwardly and thus moves the pinion 16 into mesh with the engine gear 22. In the event of tooth abutment the translation of the pinion and associated parts is stopped and these members are caused to rotate until indexing occurs whereupon the pinion is meshed due to the axial force exerted by the threads on the shaft 12; just prior to the pinion abutting a stop 34 the collar 30 passes through the aperture in the disc 27 and contacts the disc 26. When the pinion abuts the stop 34 the disc 26 is displaced so reducing the braking effect on the sleeve. As soon as the engine is selfoperative the pinion 16 rotates freely due to the free-wheel 20 which transmits a disengaging moment to the sleeve but since this moment is smaller than that exerted in the engaging direction by the brake the sleeve is urged toward gear 22 whilst the starting motor is operative. After de-energizing the motor the brake quickly reduces the armature speed and a compressed spring 21 withdraws the pinion; upon completing the initial withdrawal all the discs come into contact and exert a strong braking action on the sleeve.

Filed: 1961-05-26
Abstract: 985,027. Magnetic core storage devices. SPERRY RAND CORPORATION. May 26, 1961 [Dec. 8, 1960], No. 19143/61. Heading H1T. Non-destructive sensing of a " thin film " magnetic storage element 10 having a drive conductor 22 to set the magnetization in either sense along an easy axis 20 is effected by a narrow interrogate winding 32 which when pulsed reverses the magnetization of a small portion 12 of the film so as to provide an output in a sensing winding 36 adjacent the winding 32. The state of magnetization of the small portion 12 is subsequently restored by the magnetization of the remaining portion 14. should the initial magnetization of the film be in its other sense the field produced by the interrogate pulse will be in assisting relationship as no output pulse will arise in the sense winding. The interrogate winding may cross the easy axis at any position (e.g. the centre) and may be a strip conductor having a width equal to 5% of drive conductor. In one construction (Fig. 2, not shown), a glass substrate bears the film which carries the interrogate and drive windings. An insulating substrate separates these from the sense winding. Windings which mirror the drive and interrogate windings are disposed on the opposite side of the glass substrate to constrain the portion 12. Coincident current windings are envisaged.
