Title: Apparatus for the spherical grinding of billiard ball and other blanks
IPC: B24B11/06
Filed: 1931-11-12
Abstract: 375,680. Grinding balls. KADZIK, 0., 2A, Schlossgasse, Vienna. Nov. 12, 1931, No. 31389. [Class 60.] Disc, wheel and roller apparatus; block rubber and like apparatus.-In a machine for grinding balls, particularly billiard balls, the blanks are mounted in an annular guide and are engaged by an annular grinding-ring supported on springs whose tension increases automatically during operation so as gradually to decrease the pressure exerted by the grinding ring on the blanks. A bearing 2 secured to the table 1 receives an extension 4a of a member 4 which is provided with a spherical surface 4c on which the balls K rest. A shaft 5 driven by a pulley 9 rotates in the extension 4a and carries a splined cone member 6, which may be of wood. The cone is urged downwardly by an adjustable spring 12 and forces the balls against a grinding-ring 14 which rests on a disc 15 supported by adjustable springs 16 which tend to reduce the grinding-pressure. The cone and the member 4 are driven in opposite directions by open and crossed belts, the speed of the cone being the higher. The grinding-ring 14 may either be rotated by the balls or it may be held against rotation by bolts 20 passing through a bracket 21. In operation, the sleeves 17 which house the springs 16 are adjusted according to the required finished diameter and at the commencement the weight of the grinding-ring is lightly relieved by the springs. As the ball diameter is reduced the springs are compressed and the pressure of the grinding-ring is progressively reduced, the operation being completed when the ring 15 rests on the sleeves 17. The rate of grinding may be varied by adjusting the spring 12. For polishing the ring 14 and cone 6 may be lined with felt.

Title: Improvements relating to prepayment gas meters
IPC: G07F15/00
Filed: 1938-11-01
Abstract: 520,840. Prepayment gas meters. THORP, H. T. Nov. 1, 1938, No. 31575. [Class 27] in prepayment gas meters governing means are provided which. automatically reduces the pressure of the gas when the prepayment is approaching exhaustion, and allows the consumer to receive the gas at the reduced pressure even after the payment is exhausted. Fig. 4 shows a meter in which gas entering at a passes by a passage b through a valve-way c into a duct d from which it proceeds by transfer valves and metering chambers to the outlet. The valve g of the valve-way c is fixed to a diaphragm h on which rests a weight i having a lost motion connection with a bell-crank j controlled by a cam m. While most of the gas paid for is being supplied the bell-crank roller bears against the major lower portion of the cam m, thus allowing the weight i to exert its full effect against the pressure of gas below the diaphragm h and maintain the valve-way c fully open. Toward the end of the supply the bell-crank roller rises on to a hump k and lifts the weight i to allow the gas pressure to raise the diaphragm h and nearly to close the valve g. The cam m is driven by the metering mechanism and a slip clutch may be provided in the drive to allow the cam to come to rest after part of a revolution, thus preventing re-instatement of full supply with continued rotation of the cam. Alternatively the cam m may have an outer and an inner track to allow of extended rotation of the cam after the supply has been cut down. Fig. 4 shows a further modification in which a second hump k<SP>2</SP> causes the weight i to be raised still further, and, by means of headed pins p, to give a direct lift to the valve g to close the valve-way c after a short period of low-pressure supply.

IPC: H04L1/18
Filed: 1963-08-09
Abstract: 1,058,908. Telegraphy. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Aug. 10, 1964 [Aug. 9, 1963], No. 31601/63. Addition to 1,024,662. Heading H4P. An error correcting data transmission system generally similar to that described in Specification 1,024,662 employs a single frequency return signal, cessation of which normally indicates reception of an error. A counter at the transmitter is started when the return signal ceases, and if the return signal reappears within a certain time an error correcting procedure is initiated. If the return signal is still absent, however, the transmitter is stopped. When the counter starts, a deliberately mutilated character is transmitted and the transmitter punched tape is then reversed; this character ensures that a repetition cycle is initiated if the absence of the return signal had been simulated by noise. In the embodiment, as in the parent Specification, the receiver perforator is not reversible and a counter controls the perforating during repetition. Upon the transmitter counter reaching a certain count the tape is reversed to normal if the return signal is now present, but if it is still absent, e.g. due to a line break, the counter continues until a start-of-block signal is detected, whereupon the transmitter stops. The system must now be set up manually.

Abstract: 446,682. Portable endless-belt conveyers for loading and stacking. WHITE, A. F., 130, Glendale Avenue, Toronto, Canada. Nov. 3, 1934, No. 31634. Convention date, Nov. 4, 1933. [Class 78 (i)] In a stacking and loading-apparatus, of the kind in which a truck travelling along a permanent-way, carries two conveyers, one of which receives the material and delivers it to the other ; the latter being movable about vertical and horizontal axes to deliver to either side or at the end of the truck, the second conveyer is carried by a boom mounted on a rope - operated turntable at its lower end and carried by a rope passing round a pulley on a mast at its upper end, a common motor being connected alternatively to three rope drums to perform the hoisting and slueing operations. In addition, the motor also traverses the truck along the rails. In the illustrated form the feeding conveyer comprises an endless belt 4 carried in part by a cantilever extension at one end of the carriage, and receiving the material at a suitable point for delivery to a hopper 12, the latter delivering in turn to a hopper 21 which slues with and feeds the delivery or stacking belt conveyer 20. The latter is carried by the boom 19 supported by pulley tackle 27 at its outer end connected to a luffing-drum 40, and pivoted at its inner end to the turntable 13 for slueing. The struts 22 and ties 23 for the boom are mounted to the rear of the axis of the turntable, but preferably overhang the latter so that the swivelling axis 24 of the guide pulley 26 is in vertical alignment with the axis of the turntable. Luffing, slueing, and the traversing of the carriage on the rails are effected from a single motor by closing corresponding clutches, thereby setting alternative sets of gearing in action. For slueing, the ends of a rope passed round the periphery of the turntable are connected to two driven drums in alignment, one of which pays out while the other winds in. Luffing is effected by a drive through a compound spur train, and traversing along the rails by chain-and-sprocket gear driven from the shaft which carries the luffing-drum.
