Abstract: 108,126 LIGHT SCANNING ASSEMBLY FOR ELECTROPHOTOGRAPHIC  PRINTING PLATE MAKING APPARATUS          ABSTRACT OF THE DISCLOSURE             A light scanning assembly for electrophotographic printing plate making apparatus of the type which comprises an enclosure which houses a copyboard, an optical train and a carriage.   The carriage moves in a horizontal path beneath a platen carrying a sheet of electrophotographic material.  The carriage has a corona device, a slot, a toning device, including an electrical development: electrode or bias plate and means for withdrawing excess toner from the electrophotographic sheet after toning.  The copyboard is loaded in horizontal position and moved along a guide track to a vertical position   When the copyboard is vertically oriented, the light scanning assembly is translated across the face of the copyboard in synchronism with the movement of the carriage to project the pattern on the copyboard horizontally through an optical train from whence it is deviated upward to cooperate with the slit.                     The light scanning assembly comprises a support bracket mounting a pair of illuminating lamps disposed spaced one above the other respectively each with an associated elliptically configured reflector, whereby the light from each lamp is directed to a common band location across the face of the copyboard.  The support bracket is driven, for translation of the lamp pair and their common band, across the face of the copyboard synchronously with the movement of the carriage.  The light scanning assembly further includes an additional illuminating lamp mounted with its associated reflector on a second bracket secured to the first bracket for movement therewith but, pivotally coupled thereto for independent rotation across the surface of the copyboard.   This additional lamp is energized only when a transparent master or original is carried by the copyboard and the first pair of lamps are not energized.          The second bracket is pivotable to rotate said additional lamp and associated reflector along a predetermined arc during the vertical translation thereof so that the light emitted therefrom is focused along a straight line continuously directed to the center of the optical train so that the image always is in focus.  A cam wheel on the bracket follows a canted or tapered guide surface formed on a vertically arranged leg supporting said light scanning assembly to effect pivoting of the said bracket, return of the bracket being effected solely by gravity.

Abstract: ABSTRACT     An alternating current generator for use as a shot exploder suitable for firing electric detonators coupled through toroid transformers e.g. 'Magnadet' detonators.  The detonating system is energised by means of a signal that is automatically generated at the resonant frequency, thus avoiding the usual time-consuming and dangerous practice involving in-situ determination of inductance and selection of capacitors.  A power oscillator having a transistor is used to supply the energising signal.  This transistor is switched by a current feedback signal.  In the preferred form a transformer is located in series with the output, the secondary of the transformer driving the transistor.

Abstract: ABSTRACT OF THE DISCLOSURE          A compressor adapted for capacity control in-cludes a rotor mounting thereon vanes slidably, a cylinder receiving therein the rotor and the vanes, side plates secured to the opposite sides of the cylinder, a vane chamber defined by the vane, rotor and the cylinder and closed at its sides by the side plates, suction ports and a discharge port.  Suction loss produced when the pressure within the vane chamber becomes below the pressure of the refrigerant supply source during suction stroke is utilized for suppressing the refrigerating capacity of the compressor at high speed operation.  With the arrangement of the compressor, the effective area of the flow passage leading to the vane chamber from the suction ports varies in at least two stages such that it becomes smaller in the latter half of suction stroke than in the former half thereof.  Thus, in the compressor, driving torque can be reduced at low speed operation and adequate effects of capacity control can be obtained at high speed opera-tion.
