Abstract: 1521328 Automatic voltage control SONY CORP 6 Nov 1975 [14 Nov 1974] 46091/75 Heading G3R [Also in Division H2] A circuit for regulating the voltage across a load 10b connected to the output of a D.C. to D.C. converter comprises a potentiometer 11, the wiper arm 11a of which is connected to the base of a transistor 12. If the voltage across the load increases, the conduction of the transistor 12 decreases. The voltage Eo supplied to an astable multi-vibrator 2 therefore decreases so that a transistor 3a has an increased period in a non- conductive state. A transistor 4 is in a conductive state for an increased period of time so that a transistor 6 is held non-conductive for an increased period. The voltage supplied to the load via a transformer 7 is therefore reduced to maintain the load voltage constant. Protective arrangements are provided, responsive to momentary and average excessive current, and voltage overload.

Abstract: 1,270,344. Mounting rotors of electrical machines. ENGLISH ELECTRIC CO. Ltd. 18 Sept., 1970 [19 Sept., 1969], No. 46223/69. Heading H2A. [Also in Division F1] A runner for an axial flow hydraulic turbine, pump or pump-turbine has the rotor of an electrical machine attached to the periphery of the runner vanes by resilient means arranged to permit relative radial movement. The resilient means may be stressed at assembly such that when the runner is stationary each vane is loaded compressively in a radial direction. In one arrangement, Fig. 2, the rotor 6 of an electrical generator carries poles 10 and is secured to the tip 20 of each vane of a turbine runner by a spring device 8. The latter comprises two stacks of conical spring washers 12, 14 separated by a flange 16 on a stud 18 screwed into the vane tip 20 and surrounded by a tubular housing 22 screwed to a flange 24À2 of rotor 6. The washers 12, 14 are thus held in compression and permit radial movement of rotor 6 relative to the vanes under thermal or centrifugal influence. Housing 22 may be filled with a damping liquid. Figs. 3 to 13 (not shown) illustrate arrangements which are basically similar to Fig. 2. In a further modification, Fig. 14, the generator rotor is secured to each vane by a stud 100 screwed into the vane tip. A bush 102 surrounds the stud and is bonded to a rubber or plastics cylinder 104 bonded in turn to a sleeve 106 fitted within a cylindrical housing 108 formed in the rotor. In a modification, Figs. 16, 17 (not shown), the bush 102 is replaced by a stack of rubber or plastics annuli, each annulus (110) being sandwiched between a collar (112) fixed to a central stud and a corresponding collar (114) fixed within a housing (116) formed in the rotor. In a further arrangement, Fig. 18, the generator rotor is formed in four circumferential segments and each segment is secured to the tip of a vane by an elastic beam 118. The latter is secured at its centre by bolts 124 to a pair of flanges 120 on the vane and is connected at both ends to the segment by bolts 122. In order to achieve an interference fit each bolt 122, 124 is tapered and surrounded by a split collar (126, Figs. 19 to 21, not shown) having a corresponding internal taper so that when the nut on the bolt is tightened the collar expands. In a modification, Figs. 22 to 25 (not shown), the beam (128) is secured in a different manner. The beam may be divided at the vane and the two halves cantilevered from the ends of the rotor segment to which they are attached. In any of the embodiments rubber or plastic packings (e.g. 96, 98, Figs. 12, 13, not shown) may be provided between adjacent radial faces of the vane tip and generator rotor to absorb torsional and axial forces. The runner may be disposed in a tube forming part of a tidal flow hydro-electric scheme.

Filed: 1964-11-17
Abstract: 1,067,919. Printing processes. RANK XEROX Ltd. Nov. 17, 1964 [Nov. 29, 1963], No. 46844/64. Heading B6C. [Also in Division G2] A surface coating of contaminant is deposited or removed imagewise on or from a frostable surface so that, on development by softening the surface and applying a uniform electric field, only the contaminated parts of the surface produce a frost image. The contaminant may reduce the threshold voltage of the thermally softened frostable material so that, on applying a weaker electric field than is normally used for development, the uncontaminated parts of the surface remain unchanged. The contaminant may be applied by spray or roller through a stencil (Fig. 1, not shown), by evaporative transfer from a uniform layer applied to the differentially absorptive surface of an original subjected to infra-red radiation (Fig. 3, not shown) or by direct contact with an original carrying an image-wise coating of contaminant, such as natural oils in the human skin (Fig. 4, finger printing, not shown). Alternatively, a uniform coating of contaminant may undergo image-wise removal by evaporation at the light struck areas of an intense, optically-projected image (Fig. 5, not shown). In this form, a continuously moving web (25) receives contaminant from an applicator roller (38) and is carried past an exposure station, a charging device (41) and a heater (42). The contaminant used is a fluorocarbon. The frost image is erased, for re-use of the material, by heating to a temperature higher than that used for development. In a xerographic application, Fig. 6, the contaminant is applied to the frostable surface by transfer from a photoconductive surface 50, on which it has been deposited by mist development, at 53, of an electrostatic latent image. The transfer to paper strip 58 carrying a frostable layer is assisted electrode 63. Charging electrodes 65 and heater 66 develop the frost image. One example of a frostable layer is a two micron thick coating of glyceryl ester of abietic acid on a conductive substrate or on a transparent insulating substrate having a conductive layer. A 50% reduction in the threshold voltage of this substance may be obtained by using dimethyl siloxane as contaminant. Other frostable materials include coumarone, styrene and indene resins and polyvinyl chloride.

In a monostable circuit comprising a semiconductor controlled rectifier of the kind which can be switched from the conducting to the non-conducting condition by the application of a suitable pulse to its gate electrode, the application of a positive triggering pulse from pulse source 9 renders the semi-conductor controlled rectifier 10 conducting whereupon capacitor 16 charges through resistor 17 towards the voltage established across load 11 until the break down voltage of the fourlayer diode 15 is exceeded, whereupon the discharge of the capacitor through the diode 15 and cathode-gate path of the rectifier 10 switches the latter off. Diode 18 provides a low impedance discharge path for the capacitor after the rectifier 10 has been switched-off. In a modified circuit. Fig. 2 (not shown), the capacitor 16 is charged through a charging resistor from the voltage established across a Zener diode connected, together with a dropping resistor, in parallel with the load. The charging rate and hence the " on " time of the circuit is thus made independent of supply-voltage variations.
