    • 469,608. Prepayment mechanism for gas meters. GIBSON, R. K. Jan. 23, 1936, No. 2108. [Class 27] Coin action, thrust and multiple coin.- As shown, pennies and shillings are in serted through different. slots intc separate coin pockets 38 and 31 carried on a disc 22 rotatable by a handle 17, a penny turning a pivoted pawl 10 so that its nose engages crown teeth on a quantity wheel 9, whilst a shilling depresses a U-shaped member 39 having a nose 5 which engages a second quantity wheel 2. Separate epicyclic mechanisms are provided for the pennies' and shillings' quantity wheels. The pennies wheel 9 is carried by a shaft 7 having a sun-wheel 55, Fig. 9, at its rear end meshing with a planet wheel 56 in a carrier 57 fast with a pinion 58 meshing with a gear 59 on a shaft 71 which is connected by gears 72 and 73 with a valve controlling cam disc 42. The return drive from the meter mechanism is made through gears 67 and 66, and a gear 65 fast with the gear 66 which meshes with an internally and externally toothed annulus 65 forming the second sun-wheel of the pennies' differential. The shillings wheel 2 is connected by a sleeve 6 and pinions 69 and 70 to a sunwheel 63 of a second differential. The planet wheels 62 of this differential are carried by the shaft 71 operating the valve disc 42 as before, whilst the return drive from the meter is taken from the toothed annulus 64 rotating the planet carrier 57 of the penny differential in the reverse direction. The gears 69 and 70 may be interchanged for operation by a threepenny piece in place of a sixpence. Indicators.-The amount prepaid but unconsumed is indicated by a dial at the front end of the spindle 88 of the valve-controlling disc 42. In addition, a gear 90 on the spindle 88 drives a crown wheel 91 calibrated on its periphery to doublethe maximum reading. The total consumption is registered on separate dials calibrated respectively in cubic feet and therms, these being driven through suitable gearing from the meter mechanism. Price-change mechanism ; coin-slit closing- devices; returning coin.-The coin-pocket disc 22 has a pin and-slot connection 24, 25 with a stepped disc 12 journalled in an annular price-change plate and fast with the handle 17. The initial position of the coin pocket, and hence the amount of rotation effective to prepay, is determined by a stop of the pricecharge plate, the latter being secured by a fixed pin engaging its toothed periphery, but being releasable for adjustment after rotation of a sealed catch 16. The pin-and-slot connection between the discs 12 and 22 provides an initial free rotation of the disc 12 to cover -the coin slots before it picks up the disc 22 to rotate the coin pockets and either quantity wheel. In its initial position, the lower front end of the pennies coin pocket registers with coincident discharge openings in the discs 12 and 22 through which an undersized coin is returned. Valves, special arrangements and applications of.-The valve-controlling disc 42, Fig. 4, has a cam track 43 engaged by a roller 44 on a bellcrank 45 connected by a pin 47 and forked arm 48 with the valve lever 50. The cam track 43 is mainly circular, but has an inturned end 43 for closing the valve when the amount prepaid is exhausted, and opens at 43 to the periphery of the disc on which the roller 44 rides when the amount prepaid is at or near the maximum.

The dial R is also readily changeable, when the calorific value is altered, being held in position by a nut X. The scales and pointers are driven from a meter shaft B which indicates two cubic feet per revolution bv a train of worm and wormwheel gearing C C , D E. F G, G H, the worms C and G being double, and the spur wheels C E. G and H having 20, 25, 20, 20 teeth respectively.

    • Ethanol is obtained by the direct catalytic hydration of ethylene by reacting ethylene and water at 250 DEG to 350 DEG C. and at a pressure of 200 to 500 atmospheres over a solid hydration catalyst consisting of the blue oxide of tungsten, using a feed rate of water in the range from 0.05 to 3.0 litres per hour per litre of catalyst bulk space and a feed rate of ethylene such as to maintain the total reaction pressure constant by compensating for any loss of ethylene from the reaction zone, and removing only the liquid phase from the reaction zone. The pressure on the liquid leaving the reaction zone may be reduced in stages down to atmospheric pressure and the liquid may be taken to a heat-exchanger where it may serve to preheat the water or the water and the ethylene to be reacted. The liquid may then be passed to a still where the ethanol is recovered as an azeotrope with water and this azeotrope may be subjected to further azeotropic distillation, e.g. with benzene to recover substantially pure ethanol whilst the water withdrawn from the still may be recycled to the reaction zone. The catalyst is preferably one of the unsupported type in the form of pellets and may be prepared from tungstic acid as described in example 2 of Specification 622,937, and this form of catalyst is employed in the examples given in which the process is carried out at 300 atmospheres pressure at temperatures of 300 DEG , 320 DEG and 345 DEG C. respectively, using a feed rate of 1 litre of water per hour per litre of bulk space occupied by the catalyst and in an example in which the process is carried out at 300 DEG C. and 300 atmospheres pressure with various water feed rates. The process may be effected in the plant illustrated in the Figure, wherein 1 is a converter containing a catalyst charge 2, ethylene being introduced via a compressor system 3 of one or more stages whilst water is introduced by way of compressor pump 4. The ethylene and water are both compressed to the desired pressure, e.g. 300 atmospheres and are then passed countercurrently to the liquid withdrawn from the bottom of converter 1 and exchange heat with the liquid. The water and ethylene then pass through a preheater 6 where they are raised to the operating temperature, e.g. to 300 DEG C. and the mixture then passes to the converter 1. The pressure is kept constant by regulating the flow of ethylene into the converter by means of a valve on the ethylene inlet line. The liquid from the converter then passes through the heat exchanger 5 as stated into catch pot 8 where some of the dissolved ethylene flashes off and may be recycled to compressor 3. The pressure is finally let down to atmospheric by valve 10 and the liquid then enters a still 11 heated by a steam coil. An azeotropic water-ethanol mixture is passed through a condenser 13 to catchpot 15 where a small quantity of ethylene flashes off and may be recycled. Water leaving the bottom of still 11 may also be recycled to the process via pipe 17.

    • 203,462. Gibson, R. K. Sept. 9, 1922. Counting-apparatus. - The usual volumetric counting-train for gas meters is arranged with the centres of the graduated circles at increased distances apart by employing twin intermediate wheels in the train. In addition to the volumetric units, thermal units may be indicated, either on a compound dial with concentric graduated circles reading to a single revolving pointer, or by means of two dials " in tandem, " i.e. one in front of the other, Fig. 3, the larger rear dials S , S , S being stationary and carrying volumetric divisions read by means of pointers I , I , I upon revolving smaller inner dials T, U, V, which themselves indicate thermal units to be read against stationary pointers P , P , P . Description is also given of arrangements in which rotating pointers read each on two stationary concentric large and small dials, graduated one for each system, and of a group of dials suitable for prepayment meters. Fig. 8 shows the arrangement of the train for such a set of dials as in Fig. 3, the movement proceeding from the six-toothed pinion A of the testing dial, through wheels B, B to C, C , D, D , and a pair of intergearing twin wheels D , D to the spindle D of the 1000 cubic feet dial S'. The other wheels shown carrv the movement to the spindles of the tens and hundreds of thousands dials S , S . There may be a recess on the dial plate for the insertion of the price per therm. Specifications 146,046, 149,414, and 184,818 are referred to.
