Title: Improvements in and relating to conveyor mechanisms
Inventor: WEBSTER ALEXANDER HYDE
IPC: B65G29/00
Filed: 1950-09-26
Abstract: 691,753. Conveying bottles &c. WEBSTER & CO., Ltd., R. W. Sept. 19, 1951. [Sept. 26, 1950] No. 23526/50. Class 78 (i). In a conveyer for bottles or the like comprising an endless belt 1 running to a star wheel 3 and feed-screw device 10 for regulating the feed of the bottles to the star wheel 3, the device 10 is pivotally mounted whereby it can be displaced transversely of the belt by a fallen or broken bottle or a bottle presented in disorderly manner and when so displaced actuates a trip or the like 24 to arrest the conveyer. The bottles are fed by the star wheel 3 to a machine such as a corking machine, being carried to and away from an operative position by another star wheel which receives bottles from the wheel 3 and later delivers them to a star wheel 6 for transfer to a conveyer belt 8. This latter belt and the belt 1 may be replaced by one continuous belt. The device 10 consists of a hollow conical element carried by a shaft 11 which runs through bearings 13, 14 in a fork 15 rotatably mounted on ball bearings 16 on a base plate 17, and is driven at a constant speed in synchronism with the star wheel 3 by a shaft 18. This shaft is connected through gearing at its lower end to the star-wheel drive comprising inter-meshing gears 21 mounted on the shafts of the star wheels 3, 6, and carries a bevel gear 19 which engages a bevel gear 20 on the shaft 11. The helix 12 of the device 10 meshes with the incoming line. of bottles on the belt 1, separates them and ensures individual smooth presentation to the pockets 4 of the star wheel 3. Spring means urge the device 10 into engagement with the bottles. If a broken, fallen or otherwise irregularly fed bottle reaches the device 10, the helix cannot mesh properly with it and as the bottle is advanced it becomes interposed between the device 10 and the opposite guide wall 2, or star wheel 3, whereby the device 10 is displaced about its pivot and an abutment 23 operates the plunger 24 of a switch or trip device to arrest the conveyer 1. If desired, the bottles may be fed to the corking machine in the opposite direction, the guide rail 22 being removable to a corresponding position adjacent the belt 1, the shaft 11 swung through 180 degrees to a position adjacent the belt 8, and the worm 10 replaced by a worm with a helix of opposite sense.

Abstract: 662,217. Electrodeposition of copper. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Sept. 20, 1949 [Oct. 13, 1948], No. 24159/49. Drawings to Specification. Class 41] An aqueous acid copper sulphate electrolyte, for the electrodeposition of copper, contains between 0.5 and 0.005 ozs per U.S. gallon of a metal from the groups consisting of zinc and cadmium. The zinc or cadmium may be added to the electrolyte as salts, for example, cadmium sulphate or oxide, or zinc sulphate or oxide. Alternatively the metal may be added as an anode of zinc or cadmium or an alloy of the two, a deplating current being applied to cause the anode to dissolve in the electrolyte. A small amount of a wetting agent may be present in the electrolyte. In the electrodeposition, there may be used a periodically-reversed current somewhat as in the process described in Specification 630,165. For example, the member to be plated may be subjected in the electrolyte to a plating current as cathode for a period of between 40 seconds and 0.01 seconds, then to a deplating current as anode for a period between 20 seconds and 0.002 seconds, the magnitude and time of application of the deplating current being sufficient to apply between 10 and 75 per cent of the Coulombs of current applied during the preceding plating period, alternate plating and deplating continuing until a deposit of copper of desired thickness has been applied. The anode may be an alloy of copper containing at least 95 per cent by weight of copper and between 0.005 and 5 per cent by weight of at least one metal from the group consisting of cadmium and zinc. Specification 633,780 is referred to.

IPC: H03F3/44
Filed: 1953-09-01
Abstract: 725,640. Valve amplifying circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 1, 1953, No. 24163/53. Classes 40 (5) and 40 (6). A variable-gain amplifier comprises two pairs of valves V1, V2 respectively, each pair having a common cathode resistance and the corresponding anodes from both pairs sharing common anode impedances R1, R2 respectively, to which output terminals 3, 4 are connected. The common cathode resistances comprise a further pair of valves V3 with a common cathode resistance R3<SP>11</SP>. The amplifier is normally balanced, so that when a signal is applied at terminals 1, 2 no output appears at terminals 3, 4. If, however, the potentials of terminals 5, 6 are changed relative to one another, the bias and hence the gain of one of the pairs V1, V2 is changed relative to that of the other. The system is then unbalanced, and an input at terminals 1, 2 will produce an output at terminals 3, 4, the phase of which is determined by the direction in which the unbalance is made. The arrangement may be used for direct-current amplification and allows of varying the gain without introducing transients into the output.

Title: Improvements in or relating to electric motor control systems including speed-limiting devices
IPC: B60L3/08
Filed: 1944-12-04
Abstract: 613,415. Master control of D.C. motors. GENERAL ELECTRIC CO., Ltd., CROFT, E. H., and TURRALL, J. C. Dec. 4, 1944, No. 24169. [Class 38 (iii)] An electric motor control system comprises a master controller adjustable over a number of steps to give a progressive increase in motor torque, and means including a device responsive to the speed of the motor adapted to reduce the motor torque to that corresponding to a lower step than the actual setting of the controller when the speed of the motor exceeds a predetermined value, the said means also being arranged to prevent a resumption of control by the controller over its higher steps until the controller has been adjusted to a predetermined lower step. A motor 4 is adapted to be a ccelerated by movement of a controller 31 to cut out a series starting resistance 7, de-energize a shunt field winding 6 and weaken a serie field winding 5 through the parallel-connected resistors 8 and 9. Rheostatic braking is prc vided by a controller 32, the armature being connected in a closed circuit with a part of the resistor 7 and a part of the series field winding 5, and the shunt field winding 6 being excited from the mains in series with a variable resistor 10. If the controller 31 is in its eighth, ninth or tenth position, and contacts 35 are closed by a speed-responsive device, a relay 37c is operated so that the shunt field winding is reconnected and full series field excitation is obtained, the motor operating, in effect, as in the seventh position of the controller. The relay 37c closes contacts 37NO2 in parallel with contacts 35 so that the relay is held energized until the controller is moved back to the seventh or a lower position. In a modification, the relay 37c is replaced by one having a first coil energized over the contacts of the controller and a second coil energized in dependence upon the operation of the speedresponsive device. Energization of both coils is necessary to operate the relay, but energization of the first coil alone is sufficient to maintain it.
