Abstract: Abstract of the Disclosure The invention relates to a dual DC voltage power supply providing positive and negative DC vol-tages including soft turn-on circuitry to limit in-rush current to substantially uncharge capacitive loads. The power supply includes a plurality of rectifier cir-cuits providing at least one positive DC voltage level and at least one negative DC voltage level from at least one AC input voltage.  A plurality of power ter-minals receive the rectified voltage, and an output terminal is provided for each DC voltage level.  A reference terminal is provided for connection to a point of reference potential.  A control for each DC voltage level is coupled in parallel relationship with the capacitive load and is responsive to the voltage developed across the load attaining a predetermined value whereupon the control provides a firing signal. A turn-on current suppressor is provided for each DC voltage level, the suppressor having a relatively high impedance connected between one of the power terminals and the output terminal wherein the impedance limits the magnitude of current supplied to the load in the absence of the control firing signal.  A switch, having a main current conduction path coupled in parallel with each suppressor impedance, is responsive to the control firing signal to provide a low impedance by-pass across the suppression impedance.

Abstract: PORTABLE WHEEL TRUING GAUGE     ABSTRACT     A pair of parallely spaced apart arms are pivotally attached to a plate member which can be attached to the fork crown of a bicycle.  A rim contacting head is threadedly attached to the arms.  The head is used to gauge both the roundness of the bicycle wheel and the deviation from the plane of its axis or degree of "wobble".  The gauge maintains the references of the "roundness" and "wobble" while the wheel is taken in and out of the forks to tighten the wheel nipples and thereby correct the wobbles and out of truness of the wheel.

Abstract: PROCESS FOR RECOVERING MAGNETITE          FROM FLY ASH                   ABSTRACT OF THE DISCLOSURE           This invention relates to a process for recovering magnetite from fly ash.  Fly ash containing magnetite is made into a slurry having 5% to 10% solids by weight and the slurry is then concentrated in a settling tank to a slurry having approximately 20% solids by weight.  The concentrated slurry is delivered to a magnetic separator where the magnetite is separated from the remainder of the fly ash.  The magnetite is then crushed in a pulverizer to a size so that 95% of the crushed magnetite will pass through a 325 mesh sieve.  The crushed magnetite is then de-livered to a second magnetite separator which is weaker than the first magnetic separator to separate the crushed magnetite from any impurities.  The purified crushed magnetite is then dried and stored.

Abstract: WHIRLFILTER          Abstract of the Disclosure A filter is described for separating solid particles and breaking down dense masses from a liquid carrier, and for promoting mixing of friable, dry material with the liquid.  The filter comprises a housing having an interior wall of substan-tially circular cross-sectional configuration.  A cylindrical filter member is carried inside the housing but is spaced apart from the housing interior wall.  A circular fluid flow path is thus defined between the wall and the filter member.  A liquid outlet port is defined in the housing and communicates with the inside of the filter member.  A liquid inlet port is oriented so as to direct the fluid flow over and past the filter so as to cause an extending filtering and filter-cleaning action.

Abstract: ABSTRACT OF THE DISCLOSURE           The forging device is equipped with two upsetting-tool holders which are shaped as angular elements.  They are installed between a head and a base, are mounted slidably in a direction transverse to the head movement and are connected with the head by articulated connectors.  The arms of the angular elements which are situated parallel to the head movement are equipped with upsetting tools.  Between the upsetting tools a gripper of the formed material is installed, which is composed of two jaws.  The arms of the angular elements, which are transverse to the head movement, are mounted slidably with regard to the jaw of the gripper in the direction transverse to the head movement.  These arms are pressed against the jaw in the direction of the head movement and cause the clamping of the material between the jaws.  After the material has been clamped, the jaws remain immobile during the whole metal forming process, The device permits to upset a rod or a tube simultaneously at two places or to manufacture branched forgings, like crosses, T-shapes, Y-shapes and the like.

Abstract: ABSTRACT: "A microwave method for measuring the relative moisture content of an object."           The known moisture meters are not reliable in the case of variation in the density and a non-uniform distribution of the object to be measured in the measuring space. Methods are described in which in known manner the complex transmission factor of the object to be measured and, which is new, also simultaneously the complex reflec-tion factor is measured. A preceding measurement in a given form for making a calibrating curve remains required. The theoretical basic ideas, confirmed by measured values, are shown for various "measuring spaces", namely for free waves and TEM guides, that is coaxial guides, for waveguides with the special case of low-loss samples and with a low dielec-tric constant and for a closed resonator.

Showalter ABSTRACT OF THE DISCLOSURE         The thinned arrayed transducer for a sonar system includes an array of sonar elements mounted in rows (layers) and columns (staves) on a structure, preferably cylindrical, to form a checkerboard pattern wherein the spacing between adjacent elements in the rows and the column is equal to or greater than .lambda.m/2, where  .lambda.m is the wave-length of the signal of frequency fo transmitted in the medium where the sonar is being used.  The transducer structure is made from a layered cloth impregnated with a phenol based material, and includes openings in which the sonar elements are mounted.  The sonar elements which are effectively a half wavelength in length consist of a cylin-drical ceramic section fixed end-to-end to a cylindrical metal section.          The metal section is made of a loading metal, such as brass.  The transmit-receive circuitry energizes the elements by row using a modu-lated signal to form a variable sonar beam.  The signals detected by the elements are combined by column or stave to provide a column output signal and the signals from adjacent pairs of columns are combined to provide the output signals for the data processor.

Abstract: Abstract of the Disclosure A display for a measuring instrument comprises an array of liquid crystal display segments forming a scale and a multi-digit numerical display in which each digit position comprises a multi-segment liquid crystal display.  An input circuit comprises a transducer, which may be responsive to mechanical, electrical or any other form of signal, and an analog-to-digital converter to provide digitized input signals.          Under the control of a signal processing circuit which may use a microprocessor, the digitized signals are applied to respective de-coder/drivers for the scale array and numerical display such that the scale is stepped by one segment for each unit change in the next to least significant digit of the numerical display.  The least signifi-cant digit thereby provides an interpolation of the input value be-tween adjacent segments of the scale array which provides a stepped or quasi-analog display.  The display may also provide limit annunci-ators driven by comparator means responsive to the current digital values.
