Title: Improvements in and relating to coin mechanisms
Inventor: KENT GRAHAM BRUCE
Filed: 1970-07-22
Abstract: 1301177 Coin testers G B KENT 22 July 1971 [22 July 1970] 35597/70 Heading G4V A coin-testing mechanism for multi-faceted coins comprises peripheral profile and rimtesting members, the rim-testing being on one or both, simultaneously or sequentially, of the flanges of the rim. In a particular embodiment a multi-faceted coin inserted through angled slot 1 falls in the direction of arrow 4 to reject path 5 if undersized, but otherwise is guided by member 2 along shoot 3 to be deflected by adjustable members 7 to a gauging member 9. If the coin is of the right peripheral contour the coin, after deflection, sits snugly in gauging member 9. At this stage, an underweight coin fails to rotate member 9 about pivot 10 against the action of counterweight 8 and is manually rejected. If the momentum of a coin is sufficient, member 9 rotates in the direction of arrow 4. An incorrectly dimensioned coin is engaged by member 17 and such a coin is rejected manually by rotating member 9 so that member 17 is rotated about pivot 18 against the action of spring 19. Reject action is combined with suitable movement of a deflection member 20. If a coin has a correct rim profile as well as size, the coin is held in gauging member 9 by rim gripper  members 11, see also Fig. 2 (not reproduced), until the latter are released by member 21 which presses the free ends of gripper members 11 together. When thus released the coin follows accept path 22. With an incorrect rim profile, a coin falls along reject path 5. In multi-coin operation, coins accepted by the above described coin tester are collected on shoot 23. When full, a further coin is deflected from the uppermost coin thereon to actuate members 26, 27 which release shoot 23 to rotate about pivot 24. The coins are thus discharged and shoot 23 is reset by counterweight 28. A stop pin 25 is positionable to preselect the number of coins required and is also removable to allow return of the coins. Movement of shoot 23 may form an electrical or mechanical connection.

Title: Improvements in or relating to electric regulating transformers for continuous voltage regulation
IPC: H01F29/06
Filed: 1933-12-18
Abstract: 411,769. Regulating transformers. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Dec. 18, 1933, Nos. 35629, 35630, 35631, and 35632. Convention dates, Dec. 17, 1932, March 23, 1933, May 24, 1933, and Nov. 8, 1933. [Class 38 (ii).] A transformer is arranged for continuous regulation by means of the provision of discshaped spirally wound coils of bare conductor arranged in pairs in parallel planes, a single current collector for each pair of coils being arranged between them, the collector having two contacts each one contact engaging the conductor of one of the pair of coils. Thus, as shown in Fig. 1, the spirally wound disc-shaped coils b are mounted on an insulating tube f surrounding the primary winding h and the core i. The turns of the coils a formed of copper strips b are separated by an insulating strip c which is wider than the coil itself so that between them spring contact plungers e may be pressed by a spring d into contact with the edges of the coils. The tube f is rotatable about its axis so that the contacts d move along the complete length of the coils to vary the output voltage, the current collected being held by a conductor g which is guided radially. Alternatively, the secondary coils may be stationary and the current collector movable around the axis, arrangements to permit its radial movement being provided, for example, as by carrying the contacts on an arm pivoted to the end of the rotatable collector (Figs. 9 and 10, not shown). Several pairs of coils, each with a current collector between them, may be provided and these pairs of coils may be placed in series or in parallel circuit. The contacts e themselves may be in series or in parallel and may be insulated from each other. The conductors passing to the contacts in each case are so arranged that currents flowing to them reinforce the contact pressure electrodynamically. Various forms of core may be employed, and different forms of shell-type cores are described either of involute form or of a series of radially projecting core sections to produce uniform flux distribution in the secondary windings. Alternatively, each pair of secondary coils may be associated with a separate core, the operating and conducting members of the current collectors g (Fig. 8) passing through air gaps in t in the core sections q, these air gaps as shown being inclined to minimize leakage. The primary winding sections may be interlinked between the turns of the secondary coils as shown in Fig. 11 in which sections h are embedded in the insulating material c between the turns of the secondary winding which project inwardly, the current collector having contacts in the form of the flanged rollers e.

Abstract: 462,570. Preventing formation of snow and ice on aircraft; reducing friction between a solid and a fluid. DUNLOP RUBBER CO., Ltd., and WRIGHT, J. Dec. 30, 1935, No. 35942. [Class 4] Means for distributing fluid over the surfaces of aircraft or other vehicles comprise a hollow member 2 containing a distensible tube 1 by which fluid is expelled from the member 2 when the tube 1 is distended. In one form the member 2 has apertures such as incisions 3 which open to a predetermined pressure, e.g. 5 lb. per square inch. The tube 1 may be locally reinforced as at 4 such that the intermediate portions of the tube may be expanded into contact with the member 2 to form a series of pockets. In modifications, the tube 1 may be of initial non-uniform crosssection or the member 2 may be formed with internal projections. The member 2 may be fed with fluid under pressure or by gravity and may be wholly or partly enclosed in an aircraft wing or strut in which case a permeable covering is placed over the incisions 3.
Patent GB-394397-A (GB)
Title: Improvements in or relating to selector switches for use, for example, for transformer tap changing
IPC: H01H9/00
Filed: 1931-12-30
Abstract: 394,397. Regulating- switches. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and BOOKER, F., c/o General Electric Co., Witton, Birmingham. Dec. 30, 1931, Neo. 35987. [Class 38 (v).] In a transformer top-charging switch of the type in which the movable contact member in being moved from one fixed contact to a succeeding fixed contact is first withdrawn with a rotary motion about the fixed contact and then advanced into engagement with the next fixed contact, the moving contact serves to control the connection of a conductor constituted by a part of the operating member or by a conductor lying on the axis of the operating member and one or other of the fixed contacts. As shown in Figs. 1 and 3, the movable contact is in the form of two or more pairs of spring contact fingers 23 with contact tips 26 reinforced by steel springs bearing on the rear of the contact tips 26 at knife-edge points 25. These contact fingers are adapted to bridge a contact sleeve on the central spindle and one of a series of fixed contacts 7 placed around the spindle. The contact fingers are supported by a contact holder 16 mounted on an overhung crank 27 on a spindle 18 mounted in bearings 17 on the central shaft, the spindle 18 being formed at the opposite end with teeth engaging an internally-toothed member 20. Thus if it is desired to move the movable contact member between successive contacts the operating shaft is moved an angular amount equal to the space 'between the contacts. During this movement. the crank 27 is moved through the gearing in the opposite direction, which has the effect of first withdrawing the movable contact with a rotary motion from the fixed contact, after which the movable contact experiences a relatively rapid rotation before being advanced and pressed strongly into engagement with the next fixed contact. In order to effect this movement the gear ratio between the spindle 17 and the teeth 20 is such that during the contact movement the spindle moves through 360‹ minus the angle between successive contacts. In a modified constructional form the contact-operating mechanism consists of a cam projection engaging shaped slots in the movable contact carrier which bears spring contacts of the type described for engaging successively the fixed contact members.

Abstract: 765,377. Mine supporting arches. STAMICARBON, N. V. Dec. 13, 1954 [Dec. 16, 1953], No. 36070/54. Class 20(2) In a mine arch comprising three or more overlapping curved girders 1, 2, Fig. 2, clamped together at 4, 5 so as to slide relatively under load the ends 6, 7 of the girders are turned or curved away from the adjacent girder. This ensures that the girders remain held in contact at the clamps during sliding movement in contradistinction to previous constructions in which girders without this curve tend to separate at the clamps and increase the clamping pressure, also ploughing of one girder into another is avoided. In an arch having trough section girders 1, 2, Fig. 3, with the open tops of the troughs directed to the outside of the curve towards the mine galley roof the end of a girder is formed with the necessary slope by cutting a notch 11, Fig. 5, in the bottom of the trough and bringing together the sides of the notch Fig. 6. The clamps each comprise hook bolts 8 and a strap 10 and may be fastened to move with one of the girders.

Abstract: 176,922. Stott, Sir P. S., and Whittaker, J. Dec. 30, 1920. Shuttles, positioning for weft-replenishing.- In looms having automatic weft-replenishing mechanism, the effective length of the shuttlebox is restricted temporarily immediately before cop-transfer and before the return of the picker, by means of a block 5, which is turned into the position shown in dotted lines, so that the picker and shuttle also can only move to the position shown in dotted lines. When cop-transfer is to occur, a cam-plate &c. 14 is turned about its pivots on the breast beam by an arm 16 connected to the weft-fork motion &c. and thereby is moved into the position shown in dotted lines, so as to engage and turn a two-armed lever 10, 11 pivoted to the shuttle-box and connected by lever mechanism 9, 8 to the shaft 6 carrying the block 5. The block may be pivoted on a shaft parallel to the lay, or may be inserted by a sliding motion. If the shuttle fails to reach the position shown, it may be moved to such a position by an ordinary shuttle-positioning device, or the loom may be stopped. According to the Provisional Specification, the block may be attached to the end of a lever, and a bunter may be employed in place of the cam-plate, or a camshaped arm on the lay may be operated by a fixed bunter.

Abstract: 511,341. Wrapping-machines. SCHWEIZERISCHE INDUSTRIE-GES., and REICHENBACH, F. Dec. 14, 1938, No. 36497. [Class 94 (i)] The machine cuts ice-cream &c. from stock so that it is positioned directly on a gravity-fed wrapper, and is conducted, in the wrapper, to various folding positions. The ice-cream, in the form of a bar S, passes down between guides 1 and rests upon knives 2, 3. A wrapper H is placed in position on a plunger 7 and the knives separate to allow the bar S. to fall so that its lower end rests on the wrapper, and approach again to sever a portion P from the bar. A pair of clamps or folders 18, 19 rise to engage the sides of the portion P, and, in so doing, turn up the sides of the wrapper so that it is 'now in trough formation. The clamps are provided with small projections 56 at the upper edges, so that two pieces cut from the abutting ends of two consecutive bars S are effectively separated and held. The clamps are arranged in a series on a spider rotating about an axis 14, and are raised and lowered, and opened and closed by the action of cams on rollers 21, 26. The clamps and plunger 7, with the portion P and wrapper H, descend to the level of a table 11, and the spider is then, moved through a series of steps to bring the portion successively to position P<II> ... P<V>. At position P<III>, a roller 30. mounted for vertical and horizontal reciprocation, moves downward to the level of the upper surface of the portion P, and then travels to the right, Fig. 1, to turn the rear upstanding flap of the wrapper down. During the next step, a stationary folder 34 turns down the forward flap, and, at position P<IV>, folders 38 on a frame 36, move downwards to fold the upper projecting ends downwards on to the ends. Folders 39 move inwards to fold the flaps 41, 42, Fig. 11. The downwardly projecting flaps 43 are turned up on to the base of the article by grooves 44 during the movement to position P<V>, and the clamps push the completely wrapped portion on to a rocking plate 46, which turns about a pivot 47 to pass the package on to a plate 52. After a predetermined number have been collected on the plate, a plunger 53 moves the batch out of the machine. A counting and checking device may be provided to ensure that the plunger can only operate when the proper number of packages are on the plate 2.
