Title: Synchronous motor including means preventing continued rotation  in a wrongway direction of the rotor
IPC: H02K7/118
Filed: 1974-05-17
Abstract: 1413782 Electric motors MALLORY TIMERS Ltd 17 May 1974 22177/74 Heading H2A The permanent magnet rotor 16 of a synchronous motor is connected to gearing through a lost motion device and is associated with a mechanical device ensuring rotation in a desired direction. The lost motion is provided by a pinion 50 coupled to the rotor by a projection 76 on the pinion or rotor disposed in a recess 78 in the rotor or pinion. The one-way device includes a stop 74 on the rotor and a gear-wheel 54 driven by the pinion 50. The gear-wheel may have projections 80 one of which will engage stop 74 on the rotor if the rotor rotates in the wrong direction. The lost motion then permits the rotor to start in the desired direction free of load. When the rotor rotates in the desired direction, the stop 74 passes unhindered through the spaces between the projections 80. In a modification, Figs. 4, 5 (not shown), the gear-wheel 54 carries a continuous disc (80<SP>1</SP>) whose peripheral edge performs the function of the projections 80, shown, the disc having in its peripheral edge a single recess (82<SP>1</SP>) which serves the function of the spaces between the projections 80.

Title: Apparatus for heat-exchange between two flowing media
IPC: F28D7/06
Filed: 1944-11-16
Abstract: 614,908. Tubular heat - exchangers DALIN, D., and HAGBY, G. V. Nov. 16, 1944, No. 22720. Convention date, Nov. 6, 1943. [Class 64(iii)] A heat-exchanger e.g. for pre-heating air by flue gases, comprises a series of U-tubes 1 in a casing 2; arranged in groups with spaces between the tubes, the air in the tubes flowing in cross current in relation to the heating gases, and in counter current with them, i.e., the heating gases enter at the side of the casing by which the heated air leaves, and vice versa. In the embodiment shown in Figs. 2 and 3, vertical and horizontal partitions 4 and 3 respectively are provided, the air entering the tubes 1 by the duct 7 and leaving by duct 6, the flue gases flowing in a plane at right angles to that of the U-tubes, entering at 8, passing round the partition 4 which has baffles 12 which may be inclined, and leaving at 9. The tubes 1 are a loose fit in a plate 5, and a gaseous nozzle 2a is provided to facilitate sweeping out the apparatus. The tubes 1 are placed in staggered relationship. Two such apparatus may be connected in series, and the U-tubes may cooperate with horizontal tubes instead of the ducts 6 and 7, or they may have their ends bent away from each other, the ducts 6 and 7 being at the sides of the casing at the top. In a modification, Fig. 14, the flue gases enter and leave at the longitudinal sides of the casing, a baffle 26 serving to divert the gases to flow in cross current with the air, but they enter in the plane of the U-tubes. The Specification as open to inspection under Sect. 91 comprises also [see Fig. 20 (Cancelled)] horizontal serpentine tubes 1a, the air entering and leaving them by vertical tubes 7a and 6a respectively, the gases entering and leaving by the bottom of the casing. Other modifications are described in which the air to be heated passes in parallel through three groups of U-tubes, and again where a fan is used to drive air through two groups of U-tubes in parallel. This subject-matter does not appear in the Specification as accepted.

Title: Ampul constricting apparatus
Inventor: JR WILLIAM EDWARD HUGHES
IPC: C03B23/18
Filed: 1954-08-05
Abstract: 746,354. Glass manufacture. OWENS-ILLINOIS GLASS CO. Aug. 5, 1954, No. 22747/54. Class 56 Constrictions are formed in the necks of ampoules A by a freely rotating disc 11 mounted in a swinging frame which is entrained in turn by each chuck 10 of a rotary series, the contact between the frame and the chuck as the latter passes the station at which the constrictions are formed, accurately determining the extent of engagement of the disc 11 with the ampoule neck. When the chuck leaves the frame, the latter swings back to engage the chuck next in sequence. The disc 11 is journalled in an arm 28 pivoted to a cranked bracket 27 secured to the end of a tube 34 slidable in a sleeve 15 which is pivotally mounted on an axle 19, the effective height of the disc 11 being regulated by a screwed bush 20 and lock nut 22. A lug 42 upstanding from the arm 28 is apertured to receive a bar 39 with a head 38, the bar being adjustably threaded in a lug 43, on the sleeve 15. and locked by a nut 45. The bar 39 may therefore, be adjusted to pull the disc 11 away from the ampoule prior to the presentation of the disc thereto. The disc 11 is pushed towards the ampoule by a spring 49 on a rod 47, to an extent determined in accordance with the desired constriction, by a nut 46 on the rod 47 which is threaded in a bracket 50 carried by the sliding tube 34, and is rotated by the nut 52. A spring 53 applies a frictional drag to prevent accidental rotation of the rod 47. The tube 34 carries a bracket 32 to which a plate 55 carrying chuck-engaging rollers 14 is adjustably secured by bolts 57 passing through slots therein. The bracket 32 also carries a guide bar 31 for the sliding assembly, a spring 34a tending to project the disc towards the ampoule. When, under the pull of the spring 24, the swinging assembly rests against the buffer 24a and presents the rollers 14 to the approaching chuck the tube 34 is projected as far as the screwed stop 40 on the tube permits, the disc 11 being withdrawn from the ampoule by the pull of the rod 39 on the lug 42 and the spring 49 being correspondingly compressed. As the chuck moves towards the line between the centre of the turret and the axle 19, the tube 34 is pressed back into the sleeve 15 and the arm 28 swings out towards the ampoule, the disc 11 moving progressively deeper into the ampoule neck. The disc 11 is cooled by air supplied through the tube 34 from the hose 36. Specification 364,211 is referred to.
