Title: Improvements relating to machines for cleansing barrels and like receptacles
IPC: B08B9/08
Filed: 1925-03-05
Abstract: 234,428. Bass, Ratcliff & Gretton, Ltd., and Smith, A. C., March 5, 1925. Regulating. -In barrel &c, cleaning machines of the type in which a jet forming nozzle is mounted on a spindle arranged in gear connection with a motor adapted to be rotated by the supply of hot water or cleansing fluid to the nozzle, means are provided for automatically cutting off the supply of cleansing fluid after a predetermined number of rotations. Such means comprise a cam n, Fig. 1, having a slot in the periphery within which the foot of a stem m of a valve b normally engages, the arrangement being such that when the valve b is opened by means of a lever l, preferably a foot lever, the cam n is released from the stem m and begins to rotate, the stem m then riding on the periphery of the cam until, after a complete revolution, the slot in the cam again allows the valve to close. The cam is actuated through a shaft v from a wormwheel t on the spindle i of the nozzle, which itself receives motion from the turbine wheel e through its spindle g and spur geanng p, q, s. The spur gearing is arranged within an oil bath o. Adjustment of the rate of rotation of the turbine is secured by a bye-pass w, Figs. 1 and 4, controlled by a cock x which admits fluid directly to the nozzle.

Change-speed gearing between a driving sleeve 27 and a driven shaft 15 comprises electromagnetic fluid clutches 45, 47 adapted to connect sleeve 27 to sleeves 95, 21 formed with gears 105, 97 respectively, gear 105 meshing with a gear 103 fast on a countershaft 99 and with a gear 145 adapted to be connected to a countershaft, 141 by a friction-synchronised dog clutch 155, gear 97 meshing with a gear 107 mounted on shaft 99 through a free-wheel clutch 109 and with a gear 147 adapted to be connected to shaft 141 by a friction-synchronised dog clutch 163 and a free-wheel clutch 161, while the shafts 99, 141 are connected to the shaft 15 through gear pairs 111, 113 and 167, 169 and free-wheel clutches 115, 171. First speed is obtained with clutch 47 alone energised, through gear 97 and shaft 99, second speed by energising clutch 45, through gear 105 and shaft 99, third speed by engaging clutch .163, through clutch 47, gear 97 and shaft 141, fourth speed by engaging clutch 155, through clutch 45, gear 105 and shaft 141, and fifth (direct) speed by engaging a friction-synchronised dog clutch 127 between sleeve 21 and shaft 15, through clutch 47. In each higher speed, both clutches 45 and 47 may remain energised, the free-wheel clutches in the lower speeds allowing over-run, but in changing to third, fourth or fifth speeds the corresponding clutch 45 or 47 should first be de-energised so as to facilitate the engagement of the appropriate dog clutch and then re-energised to establish the speed. More than two countershafts may be used, to increase the number'of speeds. The shaft .15 is connected to a final driven sleeve 7 through reversing gearing controlled by a combined dog clutch and gear 135 and including a friction-synchronising cone 181.

Title: Improvements in or relating to electronic circuits for producing saw-tooth currents
IPC: H03K4/34
Filed: 1947-03-11
Abstract: 643,152. Sawtooth generating circuits. PHILIPS LAMPS, Ltd. March 11, 1947, No. 6785. Convention date, March 14, 1946. [Class 40 (vi)] In a circuit employing a tetrode 1 coupled from anode to control grid over transformer 6 and employing a damping diode 11 the time constant of the grid capacitor 9 and resister 10 exceeds the sawtooth period. This results in a small grid current flow and reduced power requirements for synchronizing pulses fed to the control grid. In a modification, Fig. 3 (not shown), the linearity is improved by tapping the anode of valve 1 along the primary of the transformer 6. Excessive screen-grid current when valve 1 is not passing anode current, may be avoided by including filters, Fig. 6 or 7 (not shown), which reduce the high-frequency feed-back.

Abstract: 589,379. Indicating order of play. MACKENZIE, J. H. March 19, 1945, No. 6882. [Class 132 (ii)] An apparatus for use in balloting or for deciding the order of play in games comprises a housing for holding a number of super-imposed marked discs, and a manually operable pusher arranged to co-operate with and dislodge the lowest disc and cause it to drop through an opening or slot, the arrangement being such that each player in turn can operate the pusher to receive a disc which, in the case for instance of bowls, determines the partners with whom, and the rink at which, he is to play. In the apparatus shown, depression of the manually operable member m as indicated by the arrow, causes the bellcrank lever o to move the pusher j to the right and carry with it the bottom disc of a pile of previously mixed and superimposed discs g contained in a compartment c. The bottom disc drops through an opening i<1> on to a chute k to be caught by the player. When the pressure on the member m is released, the moving parts return under the action of the tension spring r to their normal position ready for the delivery of the next disc. Players who receive blank discs are required to give up their game for the time being. The discs for any rinks which may be out of use may be placed in side compartments d and e.
