[Class 27] In a prepayment time-controlling device for the supply of gas or other commodity, a screwed spindle coacting with a nut is moved axially in one direction by the prepayment mechanism. to permit the supply, and .in the opposite direction by clockwork mechanism to interrupt the supply. As shown, a quantity wheel 7, rotated by a striker 6a of a rotatable coin pocket 5, is secured to the winding shaft 9 of a spring clockwork mechanism 10. The shaft 9 also carries a gear 11 driving a gear 12 secured to an axially immovable nut 13 in which works an axially movable threaded rod 16, at one end of which is a pin 17 carrying an abutment 20 for operating spaced arms 21, 22 secured to the spindle of a gas supply valve. As the quantity wheel 7 is rotated during prepayment, the spring of the mechanism 10 is wound up and the threaded rod 16 displaced until the abutment 20 engages the arm 21 and opens the valve. As the mechanism 10 runs down, the gear 11 returns the rod 16 until its abutment engages the other arm 22 of the supply valve which is then closed. Price-changing mechanism.-The abutment 20 operates the supply valve arms 21 and 22 through adjustable screws 21a and 22a, the setting of which determines the end position of an abutment 16b on the shaft 16 operating to discharge the coin as described below, and hence the number of revolutions of the coin pocket and the period of supply. Coin action, thrust and multiple coin.-The striker 6a is provided on a plate 6 slidably mounted on a parallel plate 3a carried by a rotary disc 3. The coin pocket 5 is radially adjustable on the plate 6 whereby it can be adapted for use with different sized coins ; it is secured in adjusted position on the plate 6 by a clamping screw 26. Insertion of a coin causes radial inward movement of the pocket 5 and plate 6 against the action of a spring 25 to engage the striker with the quantity wheel 7 ; subsequent rotation of the plate 6 by a handle secured to the disc 3 being communicated to the quantity wheel by the striker. In the second Provisional Specification, the coin mechanism is described as being applicable also to prepayment meters. Coin discharging mechanism.-The coin is retained in the pocket by the turned-over end 28b of a pivoted plate 28 until the threaded shaft has been moved back axially to such an extent that an abutment 16b thereon is brought into the path of movement of a pin 28c on the plate 28. The plate 28 is then displaced by the abutment 16b to release the coin and disengage the quantity wheel.

Title: Improvements in or relating to machines suitable for use in the manufacture of shoes
IPC: B29C35/00
Filed: 1961-07-29
Abstract: 1,029,594. Moulding rubber soles to footwear uppers. BRITISH UNITED SHOE MACHINERY CO. Ltd., T. J. BROWN, R. D. E. ELDRED, and W. A. NORTH. July 27, 1962 [July 29, 1961], No. 27611/61. Heading B5A. The machine as described in Specification 1,025,641 is modified so that the sequence of lowering the foot form and closing the side moulds may be varied by a control means so as to be either as described in the above mentioned Specification or reversed, i.e. the side moulds closed before the foot form is lowered. This is achieved by mounting pins 602 on bars 608 which are connected by a tie bar 612 so that the pins 602 can be in a position directly below pins 190 or can be swung to an out-of-the-way position, as in Fig. 2, by means of a lever 606 which has a spring 622 to hold it positively in both positions. When the pins 602 are below the pins 190 the machine operates as in the above mentioned Specification. When the pins 602 are in an out-of-the-way position, on raising the cylinder 84 to close the side moulds, the pins 602 do not engage the roller 170 and so do not lower the foot form. When the bar 608 is swung to one side it operates a switch 628 to close a solenoid operated stopcock (not shown) in the outlet pipe from the space above the piston 186, thus locking the piston 186, so that on applying fluid pressure below the piston 186 the cylinder 130 is forced down to lower the foot form. When the foot form is lowered the cam slide 164 is allowed to move across under the action of the spring 604, via the bell crank 166, this action also operating a switch 636 to open the stop-cock and so allow the piston 186 to rise. The machine then continues to operate as in the above Specification. The foot form carrier 600 (not shown) is also modified so as to be either rigidly or loosely mounted. The foot form F is attached to a plate 646 so that when the bolts 670 are tightened the foot is held rigidly against the frame 194. When the bolts 670 are slackened the plate 646 is held loosely against the block 644 by bolts 648 having hemispherical washers 652 and lock nuts 654 which are not tightened against the plate 646, thus allowing movement of the foot. Lengthwise movement of the foot is prevented by guide pins (not shown) engaging in transverse slots in the strip 664. The foot may be adjusted in a heightwise direction by movement of the wedge 642.

Catalytic agents, preparation and treatment of. -In a moulded catalytic mass for gas reactions there is included a substance or substances which, under the influence of catalyst poisons present in the gases or formed in the reaction, will break up the mass and thereby indicate the exhaustion of the catalyst. For example, a pulverized mixture of oxides constituting an oxidation catalyst may be mixed with lime and the mixture moulded under pressure. The absorption of water by the lime causes the breaking up of the mass, whereupon the exhaustion of the catalyst is indicated by the increased resistance offered to the flow of the gases, by the presence of dust in the reaction products, or by the falling of the disintegrated mass through a sieve. The exhaustion of catalysts by carbon dioxide may be indicated similarly by additions of oxides or hydroxides of alkali or alkaline-earth metals, and when the catalyst poison is sulphur dioxide, additions of carbides, hydroxides, and peroxides of alkalineearth metals may be made.
