Title: Improvements in and relating to token plate imprinters and token plates for use therewith
Inventor: EVANS JEAN-PAUL ROBERT MARIX
IPC: B41L19/00
Filed: 1961-01-13
Abstract: 978,419. Vending apparatus. ACCOUNT-TOKENS Ltd. April 12, 1962 [Jan. 13, 1961], No. 1513/61. Heading A4T. [Also in Divisions E2 and G4] A device for use in an automatic vending machine which sells on an account basis checks that a number dialled into the machine by the customer corresponds to a number coded on a token plate inserted by him before printing his name, address &c., taken from the token plate, on to a record strip and before operating the machines dispensing mechanism. The token plate, having a number coded on it by the position of holes 4, is inserted in the machine displacing a bar 6 to release a lock 7 on a dialling mechanism 8. The dialling mechanism consists of a shaft 11 having a dial 9 and a frame consisting of plates 13 and a shaft 14 keyed to it. A drum 15 rotatably mounted on the shaft 14 has projecting pins 16 corresponding one to each of a set of idler gear wheels 12 which mesh with racks 25. When a first figure digit of the code number is dialled one of the pins 16 engages a projection on its gear wheel and rotates it to move its respective rack through a distance corresponding to the size of the digit. On return of the dial by spring action the rack and gear stay. in this set position. Near completion of this return movement a projection 19 on a plate 7 meets an adjustable stop 21, and thus causes rotation of the plate 7 about the shaft 14, against the action of a spring 20. A pawl 22 attached to the plate 7 co-operates with a ratchet wheel connected to the drum to rotate the drum through 30 degrees to move the first pin 16 out of position for engagement with its gear, and to move a second of the pins 16 into position. The process is repeated until all six racks are moved through their respective distances. The racks which move across just above the token plate have pins 26 (Fig. 1) pressed downwardly by spring action which pass into the holes if the correct numbers are dialled. A head 30 (Fig. 7), is lowered either automatically or on operation of a switch, and horizontally extending arms 31 come to rest against the tops of the pins 26. If any of pins are in the wrong place, i.e. the wrong number has been dialled, an arm 31 is tipped as shown to close a switch 34 to draw the plate into a receptacle in the machine, where it is stored until an attendant removes it and returns it to its rightful owner. If the pins are in the correct place the machine continues as follows: a block 38 having an inked idler roll on its lower face is moved across a portion of the token plate which has the name &c. of the customer embossed on it, to press a paper tape of a plurality of tapes with interleaved carbon or inked ribbon against the information to record it. A pivotally mounted lever 46 pushes the racks back to their initial position.

Patent GB-193243-A (GB)
Title: Improvements relating to power factor measuring or indicating instruments for use with alternating electric currents
IPC: G01R11/56
Filed: 1922-01-21
Abstract: 193,243. Chamberlain & Hookham, Ltd., and James, S. Jan. 21, 1922. Power-factors, measuring.-Maximum or minimum average power-factor is measured by the employment of an energy meter and a wattlesscomponent meter, one of which meters moves a non-return pointer and is periodically re-set after a predetermined motion of the other meter. For measuring minimum average power-factor, a wattless-component meter drives, through a worm a and worm-wheel b, a pinion d which normally engages a gear-wheel g loose on a shaft h, to which is fixed a ratchet-wheel k engaged by a pawl p. The pinion d is periodically disengaged from the wheel g by an electromagnet f, which is controlled by a cam driven by an energy meter. The wheel g, when disengaged, is returned by a spring i to its initial position, in which a pin n engages an abutment q. During rotation of the wheel g, the pin n engages a pin o on the ratchet-wheel k which indicates, by a pointer l, the maximum rotation of the wheel g. If it is required to indicate the maximum average power-factor, the pinion d is driven by an energy meter and the releasing-magnet f is controlled by a wattless-component meter. The spring i may be replaced by gravity control. A mechanical connection may be employed instead of the electromagnetic connection for causing the periodical release of the wheel g. For the measurement of minimum average power-factor in circuits where leading and lagging currents are experienced the wattless-component meter may be provided with two ind cators, one responding to a leading and the other other to a lagging power-factor. In an alternative arrangement in which one pointer indicates for a limited range of leading and all lagging currents, the wattless-component meter is adjusted so that it is stationary for a leading current of, for example, 30‹ and runs in the forward direction for anv current with a less lead than this, or for any lagging current. Specification 104,924 is referred to.

Filed: 1940-02-01
Abstract: 538,480. Moulding commutator insulation. HOOVER, Ltd., COLSTON, C. B., and BELL, W. C. Feb. 1, 1940, No. 1991. [Class 87 (ii)] [Also in Group XXXV] In a commutator with two or more rings of segments the rings are united to a common supporting core by a mass of moulded insulating material and conductors or passages for conductors extend from one or more of the rings through the moulded mass. In the 2 - ring commutator shown, two metal rings A, B with ribs or the like for engaging the insulating material D have different diameters and the material D is moulded on to the core C which is mounted on the dynamo shaft. Openings H accommodate conductors from the smaller commutator. The rings are turned down and slit after the moulding so as to form segments with risers A' and B'. The mould, Fig. 5, has one end member F<SP>1</SP> with a recess to take the ring B and the other end member G has fingers G' to form the openings H, Fig. 3. The core C is mounted on a central pin F' and the ring A is held by two mould rings F<SP>2</SP>, F<SP>3</SP>. In an alternative form of commutator, in place of conductors in the openings H extensions of the smaller segments pass through and reinforce the insulating material which supports the larger commutator. In another construction, a single metal tube, of somewhat greater length than the finished structure and stepped if desired, is, before the moulding, slit longitudinally at the two segment regions and is moulded on to an insulator with passages for conductors. After moulding, the unslotted ends and the mid-region of the tube are turned away, leaving the segments in situ. The Provisional Specification states that the outer end of the moulding may have radial grooves connecting the passages H with the outer ends of the segments and that, alternatively, a separate moulding in the form of a radially grooved cap may be used to enclose the conductors ; also that the insulating brush bars may be in the form of a U-shaped member to support the brushes on either side of the commutator.
