Title: Improvements in and relating to Dynamo Electric Machines.
IPC: H02K3/14
Filed: 1918-08-30
Abstract: 136,202. British Thomson - Houston Co., and Taylor, H. W. Aug. 30, 1918. Windings ; coils and conductors. - Consists in an arrangement for eliminating eddy currents in the laminated conductors of stator windings of alternating-current machines having coils with an uneven number of turns. In Specification 135,533, it is stated that the parasitic voltage generated in any conductor high in a slot depends upon a variable flux distribution due to its own current, and also upon a constant flux distribution due to the currents carried in the conductors below the one in question. According to the present invention, the separate laminations of the conductors are continuously insulated throughout the coil, and are so connected that the number of variable flux elements which remain unopposed is twice the number of constant flux elements which are uneliminated, the opposed variable flux elements being in opposition to the uneliminated constant flux elements. The diagram illustrates the case of a three-turn coil arranged in two slots nearly a pole-pitch apart, the conductors of the same coil being marked a - - f. The current traversing the coil passes, for instance, firstly along the top conductor f, then along the bottom conductor a, and so on in turn through the conductors e, b, d, c. The conductor is composed of five bars or laminations 1 - - 5; the bars in the conductors a, b, c, e are arranged in,the same order, while those in d, f are in the reverse order. As explained in the prior Specification, the variable flux elements of the conductors a, b, c, e, amount to four, while those in d, f amount to two, leaving two unbalanced variable flux elements. The constant flux elements of the conductors a, b, c, e total seven, while those in the second group total eight, leaving a balance of one constant flux element in opposition to the two unbalanced variable flux elements.

Title: Improvements in or connected with pre-payment mechanism for use in combination with gas meters
IPC: G07F15/00
Filed: 1949-05-30
Abstract: 684,912. Prepayment mechanism for gas meters. HELLIWELLS, Ltd., and COLEMAN, E. May, 30, 1950 [May 30, 1949]. No. 14370/49. Class 27. Maximum prepayment, preventing insertion of coins exceeding; indicators. When the credit registered by the prepayment mechanism of Specification 626,884 has reached the maximum, movement of the coin pocket to its coin discharging position is prevented and the full-stroke detent engaging the coin wheel is withdrawn to permit reverse rotation of the pocket. The coin pocket is effectively disconnected from the quantity mechanism by the unmeshing of the resiliently meshed intermediate bevel gear described in the prior Specification. As illustrated, a radial arm 5 carried by the sleeve 3 of the credit-indicating drum 4 abuts against a lug 6a on the backplate of the coin barrel 7 when the indicator drum reaches the positions which correspond to maximum debit and credit. In the latter position the arm 5 also engages a wire 10 secured to a disc 9 and turns the disc eccentrically about the spindle 8 which drives the indicator drum. The disc consequently raises a wire link 11 to disengage the full-stroke pawl 12 from the coin wheel 13 by a movement which also places a stop 12a on the pawl in the path of the coin pocket (not shown) to its coin-discharging position.

Abstract: 494,561. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd., and THOMAS, H. May 19, 1938, No. 14932. [Class 28 (ii)] In a slicing-machine, the end-piece holder is moved angularly, to cut tapered slices, by a striker lever, fulcrumed on the holder's support, contacting with an abutment, intermeshing gears being arranged between the striker lever and the holder. As shown, the holder 16 is mounted on a horizontal shaft 20 journalled in the holder-support 17 which has bored lugs whereby the support is threaded on a clamp post. The holder is held in the operative position by a recess 18<1> engaging a projection on the side of the feed table, and an inclined part 19<1> of the upper lug engaging a correspondingly inclined part of the sleeve carrying the clampbar. The shaft 20 is screwed into a part 21 of the end-piece holder and a friction pad 23 is interposed between the parts 17, 21, the effect of which is adjusted by nuts 22. The holder is further supported by an arcuate web 24 thereof being interposed between a partially toothed gear-wheel 26 and a washer 25, a friction pad 31 being interposed between the wheel 26 and the support 17. The wheel 26 is keyed to a shaft 28 having an integral collar 27 and a boss 30 to which a shaft-turning knob 29 is attached. The friction of the pad 31 is adjusted by a nut 32 screwed on the shaft 28 which carries the striker arm 33. The gearwheel 26 is meshed with a toothed segment 35 on the holder and concentric with the shaft 20. As usual, the holder 16 is provided with substance-engaging prongs on the parallel shafts 37, and one side of the space accommodating the prong shaft gears and the gears 26, 35 is partially closed by two overlapping plates 38, 39 pivoted together, the plate 38 being secured to the support 17 and the plate 39 to the holder frame. In operation, the holder 16 is tilted, so that its top overhangs, by the knob 29, the striker arm 33 being correspondingly displaced. During the feed, the roller 34 contacts with a fixed, adjustable abutment, the holder being thus restored to its normal position. In a modification, the holder is angularly movable, in both directions, about a vertical axis on the centre line of the holder. One side of the holder is connected, by roller and slot means, to a slide movable at right-angles to the slicing-plane and carrying two racks, one above the other but to one side thereof, the teeth of each rack being directed towards the other rack. The racks are each meshed by a pinion mounted, as a free-wheel, on a common shaft, the free-wheel drives being opposite. The shaft is secured to a third pinion which meshes with a toothed segment on the shaft carrying the striker arm. The holder, when angularly displaced in either direction, advances the striker arm towards the slicing-plane to be subsequently moved back by the abutment with corresponding movement of the holder into parallelism with the slicing- plane.

Abstract: 1,267,272. Moulding capsules. BRITISHAMERICAN TOBACCO CO., Ltd. 16 March, 1970 [24 March, 1969], No. 15318/69. Heading B5A. [Also in Divisions B8 and F4] Liquid-containing capsules are produced by feeding the liquid portion-wise through cooling means to produce frozen solid entities which are transferred to apparatus which evenly coats the entities with a material which is then caused to solidify and the frozen contents to melt. Water from a tank 6 is injected in drops through a nozzle 5 at the base of a column 1 containing a cooled liquid mixture (see Division F4) of higher density than the water whereby the drops rise and become frozen into balls 12 and pass via a pipe 13 and valve 19 to a pan 21 from which they are transferred to a deep freeze cabinet. To assist the flow of the balls in the column a cooled liquid mixture in a tank 14 is injected at 18 into the column by a pump 16. The balls are fed to the apparatus of Fig. 2 where they are wax coated. Such apparatus includes a tank 23 containing molten wax into which a roller 22 with axial grooves dips. A helically grooved roller 24, rotated in the same direction as roller 22, receives the balls which are fed singly into the roll bight from a hopper 29 and feed tube 31, and under the control of a camactuated reciprocatory rod 32 which pushes each ball against a baffle plate, not shown, ensuring that it falls into the starting point of the helical groove. Each ball is carried along the bight during which it is evenly coated with wax drawn up from the tank by the roll 22. The coated ball falls into a trough 37 of cold water and passes via a further trough 391 to a shoot 41<SP>1</SP> for collection. In a modified apparatus for the feeding of the balls singly to the roller bight, each ball is fed from a tube into one of a ring of holes provided in a rotating disc above the bight, and is prevented from falling through the disc until it reaches an appropriate position.
