Abstract: PROCESS AND EQUIPMENT FOR THE DETERMINATION OF THE MAGNETITE AND PHOSPHORUS CONTENTS OF MAGNETITE-CONTAINING ORES  .                     ABSTRACT OF THE DISCLOSURE                                    _ _ Process for the determination of the magnetite and phosphorus contents of magnetite-containing ores.  A sample of dust which has been produced artificially or obtained as byproduct is collected and placed in an electromagnetic field.          The magnetite content of the dust sample is determined from changes in the magnetic flux or the relative permeability.          Subsequently the phosphorus content of the total dust sample mass is determined.  Also the total dust sample mass is like-wise determined from changes in the magnetic flux or the relative permeability.  The dust sample is preferably dried prior to measuring the change in the magnetic flux or the relative permeability.  Equipment for carrying out the process includes a coil system having at least one measuring coil for determining the magnetite content.  The core of the measuring coil forms a tube which has a minimum filling height that ex-ceeds the length of the coil.  An additional measuring coil, whose length exceeds the maximum filling height of the tube, is provided for determination of the sample mass.  The tube is connected to a reaction chamber for carrying out the phosphorus analysis.  The reaction chamber is connected to reagent storage containers.  A microprocessor is provided for evaluating the measured values and simultaneously controlling the operation of the equipment.  The tube is connected to a dust collecting unit, preferably via an elbow.

Abstract: ABSTRACT OF THE DISCLOSURE           A drive circuit for a brushless DC motor assures that the stator coils of the motor do not generate unwanted electromagnetic noise, but does not sacrifice efficiency of the motor.  The drive circuit can include an input circuit to which a rectangular switching signal is applied, a drive circuit including a drive transistor providing stator drive current in response to the input switching signal, and an RC smoothing circuit to impart sloping leading and trailing edges to the drive current so that the drive current assumes a some-what sinusoidal shape and the electromagnetic noise is avoided. In order to prevent the motor efficiency from dropping under low-torque and high-speed conditions, the delay times for the leading and trailing edges are controlled to increase or decrease in dependence upon the load to the motor.  In one embodiment, the collector-emitter voltage of the drive transistor is sensed and this voltage is furnished to a control transistor so that the latter adjusts the level of the input switching signal according to the sensed voltage level.  Preferably, the base current applied to the drive transistor is kept near the satura-tion level.                             -i-

Abstract: SPRING FEEDING MECHANISM                        ABSTRACT      Disclosed is a spring feeding mechanism for use with plumbing tools of the type having an elongated coiled spring wire, or plumber's snake and means for rotating the snake about its longi-tudinal axis.  The mechanism includes a snake engaging element movable into and out of driving engagement with the snake for feeding the snake axially of itself.  The engaging element includes first and second hingeably interconnected jaws movable from a first open position to a second closed position proximate the snake, a pair of feed rollers being rotatably carried by the second jaw.  At least one feed roller is rotatably carried by the first jaw, each of the feed rollers being adapted to rotate about an axis disposed at an angle with respect to the longi-tudinal axis of the snake and each having helical grooves formed therein adapted to operably engage the coils of the snake when the jaws are in the second position so as to urge axial movement of the snake relative to the feed rollers.  Latching elements are operably coupled with the snake engaging element  for moving the first and second jaws from the first position to the second position and for latching the jaws together in the second closed position.  The latching elements include biasing means for yieldably urging against separation of the jaws while at the same time being responsive to forces opposing axial feeding of the snake so that the feed rollers will automatically move out of driving engagement with the snake in response to such forces.

The two-layer metal-effect coating is intended still to have good mechanical properties and a high weathering resist-ance.  This two-layer metal-effect coating is achieved by obtaining the polymer resin by copolymerizing:  a)  1.0 to 50.0% by weight of acrylonitrile and/or methacrylonitrile, b)  0.1 to 10.0% by weight of a compound having 2 or more polymerizable olefinic double bonds and c)  40.0 to 98.9% by weight of other copolymerizable compounds, with the total amount of the components a, b and c being 100% by weight.
