Title: Improvements in and relating to protective systems for electric circuits
IPC: A23G1/24
Filed: 1931-03-20
Abstract: 377,219. Protective cut-out systems. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A. -(Assignees of Allgemeine Elektricitõts Ges. ; 2, Friedrich Karl-Ufer, Berlin.) March 20, 1931, No. 8674. Convention date, March 20, 1930. [Class 38 (v).] Relates to means for obtaining selective indication of and cut-out protection against an earth fault in a section of a branched hightension system unaffected by an earth fault in another section of the system which is dealt with by distance relays. The earth fault relays of each section are electrically interlocked with other relays which open when due to a double earth fault a negative phasesequence component appears in the section currents or voltages. In the arrangement shown, the branch circuit L2 from the bus-bars T, S, R have star-connected current transformers C connected through a neutral point choke coil N. The two star points S1, S2 are connected together through the current coil E of the earth fault relay which is thus supplied with the zero phase-sequence component of the line currents. The relay has a voltage coil connected to the bus-bars through the transformer H. The current transformers are also connected to the corner points of a bridge connection B of four impedances Z1 .. Z4 of which the last is the winding of a relay R1, the contacts of which are in series with those of relay E through the tripping coil AM of the circuit-breaker S1. The winding of the relay R1 carries a measure of the negative phasesequence component of the current in the event of a double earth and so by opening the relay R1 prevents the tripping the circuit-breaker.

Abstract: 611,632. Hydraulic presses. PRECISION DEVELOPMENTS CO., Ltd., OLAH, G., and BOX, F. J. March 23, 1946, No. 9033. [Class 69 (ii) In an apparatus comprising a main pump 1 and an auxiliary pump 2 supplying liquid through an unloading valve 3, feed pipe 4, and a control valve 7 to an hydraulic press, the control valve is actuated by a rod 11 which is loaded by a spring 13 or other equivalent means to urge the valve to its return-stroke position but during the operating stroke of the press the valve is prevented from moving by a trigger bar 14 engaging a notch 15 in the rod. The trigger bar is attached to a differential piston 17 in a cylinder 16 communicating through a pipe 19 with the main pump 1 and through a non-return valve 22 to the feed pipe 4. This non return valve is byepassed by an adjustable hydraulic resistance element 23. During an operating stroke of the press the trigger bar 14 is kept in engagement with the notch 15 by the liquid pressure from the main pump acting under the piston 17. When at the end of the stroke pressure increases to move valve 3 so that the main pump unloads, pressure under the piston 17 disappears and liquid from the pipe 4 flowing through the element 23 forces the piston downwards until after a predetermined time the rod 11 is free to be moved by the spring 13 to put the valve 7 in the position to cause the return stroke of the press. The unloading value 3 may be constructed as described in Specification 611,628.

Title: Apparatus for electrostatic latent image development
IPC: G03G15/08
Filed: 1972-02-29
Abstract: 1385966 Developing electrostatic latent images XEROX CORP 29 Feb 1972 [4 March 1971] 9320/72 Heading G2H An electrostatic latent image on a photoconductive surface 10 is developed by toner particles presented to it by an endless donor member 24, consisting of a dielectric body 36, an apertured or mesh electrode 38 which overlies the dielectric body and may itself be covered by a dielectric film, and an electrode 40, or array of electrodes, beneath the dielectric body, together with means by which a potential can be established between the electrodes 38 and 40 and subjected to temporary reversals. The toner particles are held to the surface of the donor member by fields which extend through the surface, and attract the particles. Loss of effectiveness of these fields, brought about by the build up of electrostatic charges between the dielectric layers or between the body 36 and the air, is prevented by reversal of the potential in question over successive parts of the donor surface, e.g. by a commutator composed of segments 30 and 32. Alternatively the electrode 38 may be made up of mutually-insulated sections connected to a commutator, and the electrode 40 may be continuous, and connected to earth, or the electrodes 38 and 40 may both be made up of sections. When a donor member with a segmented electrode transfers toner at a development station C the potential between the relevant portions of the electrodes 38 and 40 may be removed to assist toner transfer. Preferably the donor member is a rotating cylinder, but it may be an endless belt or a moving flat plate.

Filed: 1972-02-29
Abstract: 1418022 Endless conveyers CRISPLANT AS 26 Feb 1973 [29 Feb 1972] 9351/72 Heading B8A In a conveyer of the kind described in Specification 1,326,363, each endless conveyer is brought into operation by the engagement of a pinion 26 with the teeth of a rack 32. Thus as the belt conveyer units move along rails 18, the pinion 26 rolls along the rack 32 and thereby drives a belt driving pulley 12. The pinion 26 is brought into engagement selectively, with the rack 32, by the action of a member 34 which is lifted upwards from an inoperative position (dot-dash lines) to an upper operative position by the action of a drive cylinder 38. Another drive cylinder 40 controls the direction of rotation of the belt 4 according to whether the rod 34 is disposed in the position shown in full lines, or the position shown in broken lines. The member 34, according to its direction of inclination engages the drive spindle of the pinion 26 and deflects it on to either rack teeth 32 or rack teeth 32<SP>1</SP>. Torque of the rotating parts is so designed as to increase the pressure of driving engagement of the pinion 26 with the rack teeth. In a modification (Figs. 4 and 5, not shown) the rack 32 and pinion 26 are replaced by friction surfaces (46), (48), and a pulley (45). The friction surfaces may be provided by runs of a belt passing over pulleys (49). In a further modification (Fig. 7, not shown) the rack 32 is replaced by an electrical conductor rail (62). The pinion 26 is replaced by shoes 60 which slide on the conductor rail and transmit electric current to a drive motor 64 of the pulley 12. There is a separate rail (62) corresponding to each direction of conveyance of the belts 4. Other variants of the latter arrangement are described with reference to Figs. 8 and 9 (not shown).
