Abstract: ABSTRACT OF THE DISCLOSURE         An optical reproducing apparatus includes an optical pickup device which projects a laser beam onto a record disc having an information signal recorded in a plurality of record tracks thereon and which reproduces the information signal from the modulated laser beam reflected from the record disc, the optical pickup device including an objective lens movable in directions toward and away from the record disc to focus the projected laser beam onto the record disc; a focus servo control arrangement which moves the objective lens in the directions toward and away from the record disc in response to a focusing error signal which, in turn, is produced in response to the modulated laser beam, so as to focus the projected laser beam onto the record disc; a laser beam tracking device which rapidly moves the laser beam projected onto the record disc, during a search mode of operation, in a direction transverse to the record tracks to a desired position with respect to the record disc; a track jump signal generating circuit which produces a track jump signal in response to a track jump command signal to control the laser beam tracking device to rapidly move the projected laser beam to the desired position; and a current divider circuit which reduces the level of the focusing error signal, at least during the duration of the track jump signal, in response to the track jump command signal.

Abstract: ABSTRACT:             SIDE DISCHARGE CONVEYOR ASSEMBLY A conveyor assembly follows a pathway defined by a supporting framework, wherein the pathway may include serpentine portions.  The framework supports a transport mechanism for movement along the pathway, and a belt assembly is carried by the transport mechanism. The belt assembly includes a continuous belt having flexible convolutions permitting the belt to follow serpentine portions of the pathway and also permitting the belt to locally laterally tilt for side discharge without requiring the transport mechanism to similarly tilt.  A pivotal member between the transport mechanism and belt assembly permits the belt to tilt laterally, such as on a hinge point laterally offset form the center of the conveyor pathway.  An actuator causes a selected portion of the belt to tilt on the hinge point.  A suitable actuator includes a camming member located on the opposite lateral side of the supporting framework from the hinge point, and the belt assembly may include a tiltable arm extending over the camming member for interacting contact. The camming member may be longitudinally movable for varying the longtiduinal position of discharge and also may be vertically movable for varying the degree of tilt imparted to the arm and, in turn, to the belt assembly.  The inverted return run is provided with a retaining rail to prevent the belt assembly from tilting under force of gravity.

Abstract: ABSTRACT OF THE  DISCLOSURE      A battery to be charged is connected to the stator winding output terminals of a permanent magnet alternator by way of two half-wave rectifier circuits. Each rectifier circuit has at least one controlled rectifier in series with the battery.  The controlled rectifiers have gate terminals, respectively, for supplying a signal that renders them conductive.  A semiconductor isolating or shut off switch, preferably a transistor switch, connects the battery terminal to a voltage divider circuit that develops two discrete voltage levels that are proportional to battery voltage. A zener diode circuit fed from the battery provides a stable reference voltage.  A first comparator compares one of the voltages that corresponds with the battery voltage being a predetermined amount below full-charge condition with the zener reference voltage and if the reference voltage is exceeded, the comparator trips to turn on one of the SCR diode rectifiers for charging the battery at a relatively low rate with half-wave rectified dc.  A second comparator compares a still lower voltage in the divider with the zener reference voltage and trips to effect turning on the other SCR diode to charge the battery additionally to the other SCR and the half-wave rectifier circuit in which it is connected.  Thus, full wave charging occurs.  If the bat-tery is accidentally  disconnected high voltage could develop on the alternator terminals.  Disconnection turns off the isolating transistor and the controlled rec-tifiers lose their gating signals and turn off.  High voltage across the alternator during the last half of the cycle before turn off is dissipated to ground by a zener diode.

Abstract: "TURBOCHARGER"                ABSTRACT     A turbocharger to provide pressurised combustion air for an internal combustion engine from which exhaust gases drive a turbine wheel which rotates a shaft driving the air compressor.  Rotating with the shaft is a bush having a flange at right angles to the shaft and having a counter-thrust surface facing a tapered-land  thrust bearing on one side of a plate.  The tapered lands form an annular array of successive bearing sectors about an aperture which receives the bush.  A slight step extending radially, separates the high end of each tapered-land or sector from the adjacent low end of the adjacent sector.  A groove surrounds the array of sectors.  Rebates or retrenchments opening into the groove eliminate a radially outer portion of the high end of each sector and a radially outer portion of the low end of the adjacent sector.  At the high end of each sector each retrenchment has a side or edge at an angle to the radial direction so that at each high end contact between the thrust bearing and the counter-thrust surface on the conically rotating shaft is (instead of area contact) reduced substantially to line contact thereby reducing frictional retardation of the shaft.  Notches extending radially from the aperture to part way across the sectors facilitate lubrication.

Abstract: METHOD OF FILTRATION USING    SEMIFLUIDIZED BEDS                       ABSTRACT       A method of filtering fine solids from a fluid (gas or liquid) flowing upwardly through a chamber containing a semifluidized bed of discrete filter particles.  During a filtering operation, the upper or packed section of the bed is immobilized by a porous retainer at the top of the chamber and, as the operation proceeds, the packed bed section gradually expands downwardly, and the fluidized bed section below it progressively decreases in size, thereby extending the duration of the filtration run and yielding a more uniform distribution of solids throughout the filter medium.

Abstract: ABSTRACT      A self-contained portable ventilator/resuscitator which can be operated from either an internal power source, or in the event that the power source fails, can be manually operated to provide the patient with a supply of filtered ambient gases.  The ventilator/resuscitator includes a housing (12) in which is mounted a chlorate candle (36), a filter (38), a pump (32), and control means (34).  The pump is caused to be operated by the chlorate candle and will cause ambient gases to be drawn into the filter to be mixed with the output of the candle for subsequent delivery to the patient.  The device further includes an accumulator (14) which, during normal operation, stores excess gases during the expiratory cycle, and, in the event that the chlorate candle ceases operation, can be manually operated through movement of the handle (90) to either draw gases into the accumulator through filter (38) or to force the filtered gases into the lungs of the patient.
