Title: Improvements in coin-freed automatic vending machines
IPC: G07F5/26
Filed: 1930-10-27
Abstract: 366,087. Coin-freed article delivery apparatus. BAKER, E. J., The Pines, Headley Road, Leatherhead, Surrey. Oct. 27, 1930, No. 32214. [Class 27.] In a coin-freed machine for the automatic delivery of any one of a variety of articles, the desired article is selected by the actuation of one of a series of pushbuttons, the pushbutton being mechanically held in the actuated position until the operation of the delivery mechanism. As applied to the machine described in Specification 289,503, [Class 27, Coin-freed apparatus &c.], the pushbuttons a, Fig. 2, are arranged in two vertical rows on a panel c. When a button corresponding to the article desired is pressed in against a spring e, the inner end a<2> of its stem a<1> passes through an apertured tube g into engagement with a pair of spring contact blades h to close the circuit controlling the particular delivery mechanism. The tubes g, corresponding to the rows of buttons, contain a number of rods i having bevelled ends i<1>, each stem a<1> being adapted to pass between a pair of adjacent rods. The clearance between the rods is such as to allow the actuation of only one button at a time, the movement of the rods in one tube being transferred to the rods in the other tube through a lever j, Fig. 1. A vertical sliding bar k is normally held raised by springs n but is depressed, when a coin is inserted to complete an auxiliary circuit which energizes an electromagnet. This electromagnet may operate the bar directly or operate an air valve admitting compressed air to a ram m connected to the bar. When the bar is depressed, latching-fingers l pivoted thereon bear, under the action of springs l<1>, on collars f on the pushbuttons, so that one finger engages behind the collar on the actuated button to retain it in that position. On completion of delivery of the selected article, the auxiliary circuit is broken, and the bar k is returned to release the pushbutton. Instead of pushbuttons, slidable plungers having pull rings, knobs, &c. may be used.

Abstract: 506,173. Resistance measurements. EVERSHED & VIGNOLES, Ltd., and PERRY, C. E. Nov. 23, 1937, No. 32261. [Class 37] An ohmmeter comprising a crossed-coil instrument has a variable resistance in the deflecting coil circuit, and switching means, so that before a measurement is made, the resistance of that circuit can be brought up to the calibration figure for the purpose of correcting for any extraneous resistance such as that 'due to earth spikes. The circuit of the deflecting-coil 1, includes a variable resistor 7 in series with the test probes p<SP>1</SP>, p<SP>2</SP>, the preliminary adjustment being effected with the switch 6 in its right-hand position through which current flows from the source 5. Thereafter, the measurement is made with switch 6 in its left-hand position. In a modification, alternating-current is passed through the resistance tested by employing two commutators as described in Specification 249,615, [Class 37]. A further modification provides for four operating ranges with shunt and series resistors.

Title: Improvements in machines for covering electric conductors with insulation
IPC: B29C48/06
Filed: 1954-11-08
Abstract: 780,664. Coating electric conductors by extrusion. SCHMITZ, E. [trading as ELEKTROSCHMITZ, O. H. G.] Nov. 8, 1954 [Dec. 4, 1953], No. 32275/54. Class 87(2). [Also in Group XXXV] An electrical conductor is automatically centred within its insulating covering while the latter is being extruded, by manually or automatically adjusting members which are spaced round the extrusion head, in accordance with electrical signals developed by elements which detect radial displacement of the conductor, and which are spaced round the cable in a manner similar to the adjustable members. In Fig. 1, an electric conductor is fed to an extrusion head 11 in which it is covered with insulating material e.g. synthetic or rubber, to form a cable which is drawn off by an arrangement 17 driven by a motor 18. To detect deviations from centring of the conductor within the insulation, either a constant alternating current is passed through the conductor or a source of high frequency alternating voltage is coupled to the conductor through a tubular capacitor 32 and the earthed reel of bare wire (not shown) supplying the extrusion head. Deviations in the position of the conductor then vary the relative voltages induced in six coils 28 surrounding the cable. These voltages are applied through an electronic amplifier 31 to respectively energize electromagnetically operated valves 25 controlling through conduits 24 the exhaust of six hydraulic chambers supplied from a pump 23 and associated with plungers 20 applying pressure radially to a member 19 of the extrusion head. Member 19 is thus moved automatically to centre the conductor within its insulation. Alternatively plungers 20 may be operated mechanically through worm-driven screws selectively coupled through electromagnetic couplings to oppositely continuously rotating gears. The voltages from coils 28 are also applied to coils 35 which move an iron rod 41 so that its shadow on a frosted screen indicates the position of the conductor. Alternatively the voltages from coils 28 may be applied to multiple deflecting plates of a cathode-ray tube serving as an indicator. By observing the indicator centring of the conductor may be effected manually by operation of six spring- loaded valves (not shown) controlling exhaust from the hydraulic chambers through conduits 24a. During such operation a switch 30b is open to disengage automatic control. To detect the thickness of the insulation, a gauge 15 comprises rollers 50a, 50b, Fig. 7, between which the cable passes. Roller 50b is movable with variations of cable size to move a condenser plate 52 relative to a condenser plate 53 so that the capacity variation is effective through an amplifier 54, Fig. 1, to control a reversible mechanism 55 which adjusts the speed of motor 18 in such a sense as to correct the size of the cable by control of the speed at which it is drawn from the extrusion head.

Title: Dc motor control apparatus
IPC: H02P7/14
Filed: 1974-07-23
Abstract: 1460388 Control of DC motors NIPPON-DENSO CO Ltd and TOYODA JIDOSHOKKI SEISAKUSHO KK 23 July 1974 [24 July 1973] 32505/74 Heading H2J A D.C. motor having an armature 2 and series field winding 6 is supplied from a D.C. source 1 through a sliding-contact rheostatic unit 3 having a "motor-off" position, wherein movable contacts 7, 12 engage fixed contacts 8, 13, and forward or reverse operating conditions, wherein contact 7 or 12 is moved to respectively engage fixed contacts 9, 10, 11 or 14, 15, 16, with the non-actuated contact 12 or 7 continuing to engage the fixed contact 13 or 8. Hence the motor runs in one or other direction at a speed determined by the number of resistors 4, 5 in circuit. Members 2, 6 may be reversed in position in the circuit and unit 3 may be modified to permit contacts 7, 12 to slide over resistors 4, 5. Contacts 7, 12 may be actuated by a single reversible lever or by respective levers, simultaneous actuation of the latter breaking the motor circuit at contacts 8, 13 to prevent malfunction. In Fig. 2 the unit 3 includes a large-value arc-suppressing resistor 18 bridging contacts 8, 13 and 9, 14, the motorcircuit being closed or opened by the contacts 17 of a relay whose coil 19 is controlled by seriesconnected changeover switches 21, 22, 23 and 24, 25, 26, their moving contacts 21, 24 being respectively ganged with contacts 7, 12. Thus when contact 7 or 12 is moved, the contact 21 or 24 is changed over to energize the coil 19 and close contacts 17, the motor speed being progressively increased as contact 7 or 12 engages contacts 9, 10, 11 or 14, 15, 16, which action also progressively connects resistors 18, 4, 5 in parallel with the winding 6 to progressively reduce the difference between the field and armature currents as the resistor cut out of the armature circuit is added to the series resistor chain across the field winding. The reverse action occurs as contact 7 or 12 is moved back to contact 8 or 13, the resistor 18 reducing arcing between the contacts 7, 9 or 12, 14 if they open before contacts 17. Simultaneous actuation of contacts 7, 12 prevents energization of the coil 19 and closure of contacts 17, further protection being provided in that, if contacts 17 fail to open when contacts 7, 8 and 12, 13 are engaged, resistors 4, 5, 18 limit the armature current, the field winding 6 is not energized and the motor does not rotate.
