Filed: 1942-09-18
Abstract: 560,405. Glass manufacture. MITCHELL, W. B. Sept. 18, 1942, No. 13202. [Class 56] A method of feeding charges of plastic glass to a forming machine consists in heating one end of a glass rod, tube, or strip until it is softened, and then cutting off a portion of the softened glass. The rod is rotated during the heating operation and is advanced through a predetermined distance after severance. The glass rod a is carried by a releasable chuck b which is rotatable about a vertical axis and supports the rod preferably in a vertical position. The lower end of the rod is heated by gas burners e, f, and after a predetermined time, shear blades c, d close and cut off a portion from the softened part of the rod. The blades are so arranged that the charge, as it is severed, is thrown into a funnel h which directs it into the mould of an automatic press, for example. Immediately after severance, the blades are separated and a stop g rises vertically into contact with the lower end of the rod a. The chuck is opened and the stop g descends through a predetermined distance, the rod a following it. Finally, the chuck grips the rod again, the stop g is lowered to the position shown, and the cycle is repeated. If desired, the stop g may be brought into contact with the glass rod during the heating operation to assist in shaping the lower end of the charge.

Title: Improvements in or relating to multiple speed gear mechanism
IPC: D06F37/36
Filed: 1951-06-06
Abstract: 690,975. Change-speed gearing; friction clutches. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. June 6, 1951 [June 10, 1950], No. 13390/51. Class 80 (ii). Two-speed change-speed gearing, particularly for washing machines, comprises a driving shaft 21 selectively coupled through a worm 29 or spiral gear 28 to a driven shaft 14. The worm 29 is integral with the driving shaft 21 and meshes a worm wheel 35 on a countershaft 23 to which latter is secured a gear 36, meshing a gear 37 rotatable on a shaft 22 splined to the driven shaft 14. Gear 37 is coupled by a oneway helical coil clutch 41 to the hub of a spiral wheel 38 fast on shaft 22. The spiral gear 28 meshes spiral wheel 38 and is rotatable upon but selectively clutchable to the driving shaft 21 by a helical coil clutch 33 in series with a centrifugally operated friction clutch 34. The helical coil clutch 33 consists of a hub 44, fast on the driving shaft, surrounded by a helix 47 which also surrounds a hub 45 journaled on the driving shaft. The helix 47 has a projection 48 at its upper end which can be engaged by an electromagnetically controlled stop 49 to prevent it from frictionally coupling hubs 44, 45. Hub 45 is connected through a sleeve 59 to two weights 56 urged apart by springs, friction linings 57 being affixed to these weights. The friction linings can engage the inner surface of a cup-shaped member 54 connected by a sleeve 32 to the spiral gear 28. When the stop 49 is withdrawn, hubs 44, 45 are frictionally coupled by helix 47 and the weights 56 are rotated by the driving shaft 21 and coupled frictionally to the cup member 54. The initial gentle engagement of weights 56 with cup 54 is produced by the springs acting between them, increasingly fierce engagement resulting from the centrifugal force produced by their rotation. Thus spiral gear 28 rotates with driving shaft 21, and a high-speed drive is obtained' through train 28, 38, 22, 14, helical coil clutch 41 overrunning. When the stop 49 is engaged, a low speed drive is obtained through train 29, 35, 23, 36, 37, 41, 38, 22, 14, spiral gear 28 rotating freely on the driving shaft. Specification 527,540, [Group VIII], is referred to.

Title: Method for regulating anode-cathode spacing in an electroly tic cell to prevent current overloads and underloads
IPC: C25B15/06
Filed: 1974-03-26
Abstract: 1458901 Automatic control of electrolysis OLIN CORP 26 March 1974 [10 May 1973] 13416/74 Heading G3R  In an electrolytic cell with a liquid cathode and one or more adjustable anode sets, the current in each anode set is measured and compared with upper and lower reference signals which are adjusted in dependence on the total cell current. If the measured current lies outside the range defined by the reference signals the position of the anode set is adjusted. As shown, a horizontal mercury cell 1 with brine electrolyte has a series of graphite anode sets 2. The current in each set is measured by sensors 4, 5 and the measured value is temperature compensated by a thermistor 6. The resulting signal is fed through an amplifier 7 to comparators 8, 16 and also, together with signals from all the other anode sets, to a circuit 9 which averages all the input signals and supplies an output to an amplifier 10 which produces a common signal on a line 11. This signal is fed to pairs of potentiometers 12, 15 associated with each anode set, the setting of the potentiometers being chosen so that a desired proportion of the common signal forms a reference value for each of the comparators 8, 16. If the signal derived from amplifier 7 lies outside the range defined by the reference values, one or other of the comparators 8, 16 energizes a corresponding relay coil 13, 17, thus actuating a motor 14 which raises or lowers the anode set 2. If the signal on line 11  falls below a predetermined minimum level, its value is supplemented by a source 19. A digital voltmeter 21 can be selectively connected to the line 11 or to any one of the amplifiers 7 indicating measured anode currents. Operation of the anode adjusting motors is indicated to an operator by lamps 22, 23 and 26, 27 associated with relays 13, 17 and latching relays 24, 25 respectively.

Abstract: 475,165. Variable resistances. STEATIT - MAGNESIA AKT.-GES. May 12, 1936, No. 13482. Convention date, May 24, 1935. [Class 37] In a variable electric resistance or potentiometer comprising a resistance of arcuate form and a movable contact carried on a rotary spindle and sliding on the resistance, the bush in which the spindle is mounted serves to press into conductive contact with one another two conductors, one or both of which surrounds the bush and one of which makes contact with a point on the resistance to establish an additional but fixed tapping and the second of which forms the means by which external electrical connection is established with the fixed tapping. The resistance b is in form of a semi-conducting layer on an insulating support o, the ends being connected to contact lugs, and a sliding contact moves over the resistance, being carried by a rotary spindle c and connected with its contact lug g by means of a tubular metal rivet f forming the bush for the spindle c. A ring p of conducting material surrounds the spindle c and is formed with a projection q which engages the inside or outside edge of the resistance b. The projection q and the ring p are respectively pressed into engagement with the resistance b and the contact lug k arranged on the surface of the insulating base a by the bush f, an insulating member i being interposed between the parts f, p. Alternatively, the member i and ring p may be replaced by a ring of insulating material having a projection similar to the projection q, all of which is coated on its lower side with a suitable conducting material. In a modification, the resistance track b is arranged directly on the base a and a radially-directed coating strip of silver is applied to the resistance at the tapping point, the coating extending inwardly over the base a and terminating in a flat ring surrounding the spindle c. A contact lug having an inner ring portion is pressed on to the ring by the tubular bush f, a layer of insulating material being interposed between the bush and the contact member. The bush f may be coated with a semi-conducting layer so as to avoid oxidation of the metal surfaces.
