Apparatus for carrying out the process comprises a pressure generator having a feed device for granular fuel, a tar separator, and a pelletising device connected by a tar conveying pipe to the tar separator, for the addition of binder to the granular fuel, the pelletising device conveying the pellets produced thereby into the feed device. The granular fuel is screened to pass only that portion below a predetermined grain size to the pelletiser, the remaining portion being fed directly to the generator.

Abstract: Abstract of the Disclosure A method and apparatus for infusing fluids into the human body includes a peristaltic-type pump and an administra-tion set having a vinyl tubing section on which the pump acts. To prevent the release of dissolved gas in the tubing section and the possible coalescence of released gas bubbles into pockets of air the pressure in the tubing downline of the pump is increased by partially restricting the lumen of the tubing.  This restriction also assists in restoring the tubing to its original shape following compression by the peristaltic pump for more accurate metering and more efficient pumping action, and prevents uncontrolled gravity flow in the event of a pump failure.  To provide a uniform compression force on the tubing the pressure rollers of the peristaltic pump are individually spring biased against the wall of the tubing, which is held in position by a stationary pressure plate.

Abstract: VOLTAGE REGULATION IN AN ELECTRONIC ENGINE CONTROL    SYSTEM HAVING DIGITAL EFFECTOR ACTUATORS                     ABSTRACT OF THE DISCLOSURE      The unregulated AC electrical power provided by an engine driven alternator to an airborne electronic engine control system which controls the performance of a gas turbine engine, is rectified to provide unregulated DC voltage signals for system electrical power.  The system provides position control of a plurality of controlled surfaces within the engine through a plurality of digital effector servo actuators, each of which includes a mechanical assembly for providing displacement of the surface in each of two directions in response to a magnetic field provided by a respective one of two oppositely polarized solenoids disposed within the actuator.

Voltage regulation circuitry provides voltage regulation gate signals having an ON portion with a time duration proportional to the excess amplitude of the unregulated DC voltage signal amplitude above that of a reference voltage level, and presents the regulation gate signals, simultaneously, to both solenoid gated switches in each of the plurality of actuators in the absence of a position gate signal to the respective actuator to provide cancelling magnetic fields which inhibits actuator displacement while increasing the current load to cause attenuation of the unregulated voltage signal amplitude.

Abstract: EXPANDING AND BEADING APPARATUS FOR TUBES AND THE LIKE      ABSTRACT OF THE INVENTION         An apparatus is disclosed for expanding and beading the end portion of a steel tube positioned within an opening of a tube sheet for use in boilers, heat exchangers and the like.          The apparatus accomplishes the expansion and beading of the tube with relative portability, substantial efficiency, and minimum noise levels.  An elongated housing has one end portion adapted to be inserted into the tube with a plurality of rollers mounted for rotation about the periphery.  The rollers are tapered slightly and offset at an acute angle with respect to the central axis of the housing.  A mandrel having a taper opposite that of the rollers is positioned therebetween such that insertion of the housing into the tube while rotatably inserting the mandrel between the rollers causes the rollers to roll into the tube along a helical path while shifting radially outward to expand the tube and develop generally axial and substantial inward forces.  A beading roll is positioned on the housing and loosely retained so as to engage the end of the tube so as to cold work the end of the tube to provide an arcuate bead in sealed relation with the tube sheet.  Substantial forces are transmitted to the beading roll via the housing and these forces are sufficient to deform the end of the steel tube by cold working.  The beading roll is capable of transferring these cold working forces to the tube primarily by the provision of two substantial support rollers mounted on roller bearings.  An offset bearing member is mounted on the housing to engage and roll along the inner surface of the tube so as to offset bending forces produced by the beading roll on the housing.  An alternate embodiment utilizes dual op-posed beading rolls while eliminating the offset bearing member.

A signal, having a parameter to be controlled, is provided; and a detecting circuit detects when the parameter is within a pre-determined range.  An UP/DOWN counter counts clock pulses and is responsive to the detecting circuit for counting in one direc-tion when the detected parameter is greater than the predetermined range, for counting in a second direction when the detected para-meter is less than the predetermined range and for ceasing its counting when the detected parameter is within the predetermined range.  A parameter control circuit uses the count of the counting means as a control signal to adjust the parameter so as to bring said parameter within the predetermined range.  A typical applica-tion of the automatic adjustment system is a white-balance control system for use with video camera apparatus.
