Abstract: AUXILIARY POWER SYSTEM AND APPARATUS     Abstract of the Disclosure An auxiliary power system for an internal combustion engine.  The system employs a vapor or hot gas engine coupled to an internal combustion engine by means of an overrunning clutch assembly.  The internal combustion engine, operated conventionally, generates heat in its cooling and exhaust systems as well as in accessory equipment.  The heat generated in the internal combustion engine and its accessories is used for generating vapor in one or more heat exchangers, the vapor preferably being from a liquid with a boiling point well below that of water.  The generated vapor is used to drive a vapor engine.  Temperature-sensitive means is employed to measure the heat generated in one or more parts of the system for controlling a linear solenoid valve for automatically control-ling the internal combustion engine temperatures and thereby the amount of vapor generated.  A vacuum-controlled throttle valve is also employed in conjunction with the solenoid-operated valve for automatically controlling the input of vapor to the vapor engine for controlling its idle speed and for providing maximum acceleration as needed.  Safety valve means and vapor condensing means are provided at the output of the heat exchangers and steam engine to condense the generated vapor for recirculation in the system.

Abstract: SWITCHING VOLTAGE REGULATOR     WITH LOW RFI NOISE    Abstract of the Disclosure To convert an unregulated input voltage applied across an input and a reference terminal to a regulated output voltage across a load between the reference and an output terminal, a switching transistor is connected in series with an induction coil between the input and the output terminals.  A flyback diode is connected between the reference terminal and the juncture between the transistor and the first coil, and is poled to be reverse biased when the transistor is conductive.  The transistor is cyclically (a) switched from full conduction to cutoff to interrupt a current flow between the input and the output terminals and through the coil to induce a voltage across the coil to establish a current flow between the reference and the output terminals and through the diode, (b) switched from cutoff to partial conduction at a controlled rate to reduce the current flow through the diode at a relatively slow, controlled rate, and (c) rapidly switched from partial con-duction to full conduction when the current flow through the diode has been reduced to a predetermined value.  The gradual reduction of current flow through the diode reduces "snap off" of the diode and minimizes RFI (radio frequency inter-ference) noise generated thereby, and the value of the regulated output voltage is controlled by the duty cycle of the transistor.

The novel process results in an unexpected great saving of reaction time and of energy. Exceptionally small amounts of catalytically active acids are required and, consequently, the products obtained contain only very small amounts of ionic compounds.      The products have excellent mechanical and electrical properties and are very suitable in all fields of application of aminoplast resins.

Abstract: ABSTRACT     The present invention relates to a control circuit for a brushless self-starting D.C. motor.  The motor comprises a permanent magnet rotor and a stator coil.  A component is provided which is magnetic field-dependent and which is subjected to the rotor field to determine the rotary position.          A controllable electronic servo-element is connected in series with the stator coil at a D.C. source.  The servo-element controls the flux through the stator coil in dependence on the rotary position of the rotor.  The magnetic dependent parameter changes of the magnetic  field-dependent component are converted to a control signal for the servo-element.          The control circuit comprises an oscillator having an LC resonant circuit of which the inductance is formed by the magnetic field-dependent component in the form of a sensing coil having a core.  The oscillations of the oscillator are modulated in response to the induction generated in the sensing coil by the rotor field.  The control signal for the servo-element is derived from the modulated oscillator output and the oscillator frequency is considerably higher than the rotor speed of the D.C. motor.

A radiation beam is impinged on the flocculated solids transverse the direction of travel of the solids adjacent the discharge means from the thickener, and the impinged radiation beam is detected by detector means to continually measure the density of the flocculated solids preferably by degree of absorption of radiation.  The detector in turn produces an electrical signal proportional to the density of the flocculated solids that automatically regulates and controls the rate of discharge of the flocculated solids from the thickener.
