Abstract: FOR:  SRC RESIDUAL FUEL OILS                         ABSTRACT     Coal solids (SRC) and distillate oils are combined to afford single-phase blends of residual oils which have utility as fuel oil substitutes.  The components are com-bined on the basis of their respective polarities, that is, on the basis of their heteroatom content, to assure complete solubilization of SRC.  The resulting composition is a fuel oil blend which retains its stability and homogeneity over the long term.

Abstract: Abstract A general and versatile method for quantitation of a variety of analytes which supplies a directly observable result not requiring instrumentation is disclosed.  The method is based on competing enzymic reactions, wherein one of the reactions is capable of forming a directly observable product, which is a colored product.  Direct quantitation is obtained by altering the relative amount of competing reaction catalyst with respect to control reaction catalyst. Materials capable of analysis using this method include enzyme substrates, enzymes, immunogens, and specific affinity binding partners.

Abstract: ABSTRACT OF THE DISCLOSURE           A transceiver is provided with a means for deter-mining its own prescribed frequency upon the occurrence of an adverse transient condition, such as lightning, or upon initial installation after manufacture.  Since it can safely be assumed that a transceiver's prescribe reception frequency is the same as its transmission frequency, the present inven-tion measures the period of its transmission frequency in order to determine the frequency of its reception frequency.          The exact frequency of incoming demodulated messages must be known in order for the transceiver's digital demodulator to properly demodulate the incoming signals.  A high frequency signal, such as 1 mHz, is used to increment a pulse counter and the values of this pulse counter are stored upon the occurrence of two successive negative edges of the carrier signal.  The present invention also provides means for direct-ing its carrier signal to an input port of its microprocessor during power-up sequence in order for the period of the carrier signal to be easily measured.

Abstract: PATENT     ABSTRACT OF THE DISCLOSURE           Apparatus for recording audio and video signals comprises a signal processor for producing a processed video signal and a frequency-modulated audio signal.  The frequency-modulated audio signal is obtained by frequen-cy-modulating a carrier in response to an input audio signal.  A magnetic recorder records both the frequen-cy-modulated audio signal and the processed video signal in oblique tracks arranged successively on a magnetic tape.          The recording is done selectively in a first recording mode wherein the oblique tracks are formed with spaces between successive tracks or a second recording mode wherein succes-sive tracks are contiguous.  A modulation control controls the frequency-modulation carried out by the signal processor to produce the frequency-modulated audio signal with a first modulation index in the first recording mode and with a second modulation index greater than the first modulation index in the second recording mode.

Abstract: ABSTRACT          A teaching apparatus especially for dyslectic students of the type wherein a platen carrying the work lesson is movable between a raised position in which the indicia on the worksheet is readily traceable by a student on tracing paper positioned over a window above the platen to a lowered position where the indicia on the worksheet gradually becomes indiscernible to the student.  A bellows is moved to a collapsed position in response to movement of the platen to its raised position and the bellows is operative when extended to move the platen to its lowered position.  Valve means are provided to selectively control the rate at which air is allowed to move back into the collapsed bellows to thereby control the rate of extension of the bellows and the rate at which the platen returns to its lowered position.

Abstract: ABSTRACT OF THE DISCLOSURE           The machine preferably utilizes a laser whose light output, modulated to produce a plurality of beams which move simultaneously across a photosensitive surface, thus forming a "broad brush" laser beam.  In one embodiment, the photosensitive material is in elongated sheet form and moves longitudinally while the broad brush laser moves continuously back and forth across the moving sheet.  In another embodiment, the sheet material is wrapped around the surface of a drum and the drum rotates past the laser beam, while the laser beam moves either continuously or intermittenlty so that contiguous circumferential bands of composition are formed, filling the whole sheet of material with only one pass of the projection mechanism along the length of the drum.  Means are provided for compensating for the simultaneous continuous motion of the broad brush and the photosensitive surface in order to produce straight lines of text composition which are perpendicular to the edges of the photosensitive surface.  Each sweep of the laser beam is contiguous with the preceding sweep, and in each sweep each full character, or any part of a character, which falls within the sweep path is projected onto the photosensitive surface, thus further enhancing the speed of photocomposition.  Characters and graphic matter preferably are stored in digital form by a raster image processor in order to enable this type of operation.

Abstract: WATER-BLOWN SILICONE FOAM                          Abstract This invention relates to a method of producing silicone elastomeric foam of low density.  The method mixes polydiorganosiloxanes having hydroxyl endblocking or vinyl endblocking or mixtures of both along with water to react with silicon hydride in the presence of platinum catalyst to release hydrogen gas to create a froth which cures to a foam. The combination of ingredients allows the manufacture of silicone foam having different combinations of properties than those obtained from previous methods.  Embodiments of the invention also make use of specific profoamers and specific alcohols to further modify the properties of the foams produced.  The method of this invention yields a low cost, low density, silicone elastomeric foam having physical properties which enable it to be used in cushioning and sealing applications.

Abstract: ABSTRACT OF THE DISCLOSURE     A low energy consumption water circulator device for creating a flow of water in a body of water.  The device comprises a support raft to sit on the body of water.  A number of photovoltaic panels are mounted on the raft to generate electrical energy.  A DC motor which drives a propeller at a low angular velocity is suspended from the raft in the water body.  The motor receives its power from the photovoltaic panels.  An intake pipe with an outlet end positioned close to the surface of the water body and an inlet end close to the middle elevation depths of the water body is suspended from the raft so that the propeller, during operation, is located in the intake pipe.  A water circulation device is associated with the outlet end of the intake pipe to change the direction of the water leaving the outlet end of the pipe so that it reaches the surface of the water body and does not immediately plunge back downwards.  The water circulator device is designed primarily for use in remote sites, particularly where there is no access to grid electricity.
