Title: Coin-freed vending machine
IPC: G07F5/26
Filed: 1936-08-06
Abstract: 464,735. Coin - freed article delivery apparatus. WISTOFT, S. Aug. 6, 1936, No. 21698. [Class 27] In a coin-freed vending machine having a coin-freed releasing-mechanism common to a plurality of drawers, blocking members 3, Fig. 3, for the drawers 2 are provided on an axle 1, which is freed for rotation by insertion of a coin, the arrangement being such that, on a drawer being pulled out, its corresponding arm 3 will be rotated thereby rotating the axle 1 without the other drawers being actuated by their individual blocking arms. Each drawer 2 is provided with a plate 7 having a bent arm 8 carrying a pin 9 which is engaged by the blocking arm 3 to prevent the drawer from being pulled out until the axle 1 can rotate. The arm 3 is of fork-shape having two arms 10, 11, and, when the drawer is pulled out, the pin 9 engages the arm 11 and rotates the axle 1 in the direction of the arrow. The arms 10 of the other members 3 can pass the corresponding pins 9 on the other drawers without actuating these, known means being provided for preventing two drawers from being pulled out simultaneously. After the initial movements, the pin 9 enters the fork between the arms 10, 11 so that the arm 3 cannot be held in its outer position by an instrument inserted through the drawer opening 21, while the drawer is pushed back, to enable another drawer to be pulled out for a single prepayment. The pin 9 may be on the arm 3 and coact with a fork on the drawer. In a modification, the drawers have at their front ends elongated slots 26, Fig. 10, in which engage rollers 28 carried by blocking arms 3<111>. The axle 1 carries rearwardly extending hooked arms 30 which, when the axle is rotated, rock upwardly and engage recesses 31 in the backs of the drawers. The arms 3 may be secured to the axle 1 or, as shown in Fig. 10, they may be loose but in driving connection with the axle through a pin 45 engaging a tooth 47. The releasing-mechanism comprises a vertically slidable coin-released rod 6, Fig. 6, having a pin 14 engaging a slot 20 in a quadrant 5 secured to the axle 1. Springs are provided in connection with the blocking arms or the axle to facilitate the return movement of the parts. For preventing the load from the springs from actuating a drawer when this is in its extreme pulled-out position, the fork arm 11, Fig. 3, is bevelled at 12 so that it does not transmit any thrust to the pin 9 until the drawer is partly pushed in. When the spring thrust arises from the rod 6, Fig. 6, the pin 14 moves over a curved portion 13 of the quadrant 5 so that the axle 1 is not returned by the rod 6 until the pin 14 re-engages the slot 20. To ensure a full stroke of the axle and delivery drawer, the member 5 may be provided with a toothed extension on the other side of the slot 20 away away from the portion 13, such toothed extension engaging with a pawl mounted on the frame of the machine.

Title: Improvements in or relating to the purification of minerals
IPC: C03C1/02
Filed: 1947-08-08
Abstract: The iron content of minerals such as silica sands, quartzite, quartz, gravel, sandstone, fluorspar, felspar and alumina is reduced by treatment of the mineral with a solution of titanous chloride or sulphate, and oxalic acid, each substance being present in 1/10 -5 per cent solution.  Detergents or wetting agents, and other acids or salts, e.g. 0.3 per cent sulphuric or 1 per cent hydrochloric acid by volume, or sodium chloride or sulphate may also be present. Temperatures from atmospheric to below 100 DEG  C. may be employed. Air should be excluded during the treatment, suitably by the use of nitrogen or other inert gas. After removal of the treatment solution, e.g. by centrifuging, the sand &c. is water-washed in a counterflow, washed, and centrifugally dewatered.  Prior to the treatment, the sand &c. should be well washed and should preferably have heavy minerals removed by the use of mining separation tables.  Titanium may be recovered in the titanous state from the treatment solution by reduction with zinc mercury amalgam, or with cadmium present as fine particles, or by an electrolytic method.  It is stated that less satisfactory results are obtained when the oxalic acid is replaced by one or more of the following, viz.: formic, tartaric, hydrochloric, sulphuric, acetic acids, sodium acid oxalate, ferrous sulphate, hydrazine sulphate.

Abstract: 1515346 Pulse width modulators ROBERT BOSCH GmbH 22 May 1975 [7 Nov 1974] 22154/75 Heading H3T A circuit arrangement for inhibiting the injection of fuel to an I.C. engine under conditions of excessive speed or overrun comprises a pulse width discriminator including a first circuit SV connectible to an engine speed transducer providing input pulses whose duration is proportional to engine speed and operable to simultaneously generate a first pulse of constant amplitude and a second pulse whose amplitude is proportional to engine speed and further operable to generate an inhibiting signal when a comparison of the amplitudes of the pulses indicates that a predetermined engine speed is exceeded. The input pulse train applied to terminal P2 causes negative needle pulses to be developed at point P5 having an amplitude dependent on engine speed and on the time constant of the first circuit comprising resistors R7, R27, R4, R5 and capacitor C1. The negative pulses are applied to the base of transistor T2 to which is applied a positive pulse generated by the RC circuit C3, R15 and fed back from transistor T3 through resistor R12. When the amplitude of the negative pulses predominates, i.e. engine speed is excessive, the transistor T3 conducts to short circuit the injection pulses which are present at terminal P3. A switch S 1 connected to the throttle valve of the engine operates in the idle position to cause transistor T5 to conduct thereby short circuiting resistance R4 and thus changing the time constant of the first circuit. Thus the amplitude of the negative pulses is increased so that transistor T3 will now become conductive at, or about, idling speed. A feedback connection RL is used to provide a hysteresis effect and prevent oscillation between the two states.

[Also in Division G4] Transistor bi-stable circuits are composed of two sets of two complementary pairs of Field Effect Transistors connected in series and cross coupled as shown in circuit 13 or 15 of Fig. 2 and having switching means, such as transistor 17, connecting the two circuits. In operation, as a digital storage device (Division G4), the supply voltage + V8 to circuit 15 is decreased in value to render the circuit inoperative and transistor 17 is rendered conductive to impose on circuit 15 the same conditions as maintained in circuit 13, and the supply voltage is increased thus causing circuit 15 to assume the same state as circuit 13. In an alternative arrangement (Fig. 14, not shown) one circuit may be rendered inoperative by open-circuiting one of the crosscoupling paths. The substrate of each transistor may be connected to a source of fixed potential (either 0 volts or V8) as in Figs. 6 to 8 (not shown) to prevent reversal of the drain and source polarities when the circuit is rendered inoperative. The switch connecting the two circuits may comprise one transistor as in Fig. 2 or a pair of complementary transistors connected in parallel as in Fig. 7 (not shown).
