Abstract: A drain system adapted for use in fuel processing devices, as well as in other fluid equipment applications, includes sensing means for detecting the presence of a predetermined quantity of water or other impurities separated from the fuel, or the presence of other fluids, in an enclosure or container. Drain means are also included for discharging at least a substantial portion of the predetermined quantity in response to said detection of the presence thereof. The drain means is preferably actuated and deactuation by automatic control means in order to maintain said water or other impurities, or said other fluids, at or below the predetermined quantity. The fuel processing device herein further includes means for heating fuel in order to prevent fuel waxing and clouding. Several embodiments are described which are particularly useful for treating fuel as it is transmitted to an engine or other consuming device whereas another embodiment describes a fuel processing device particularly adapted for treating fuel as it is drawn from and returned to the fuel tank.

Abstract: Abstract of the Disclosure A feedthrough assembly for a conduit has, as is known, a wall formed with a throughgoing passage extending along an axis and having a radially inwardly directed wall surface.  An elastomeric adapter sleeve has an outer surface complementarily radially outwardly engaging the wall surface, an inner surface snugly surrounding and engaging a conduit passing axially through the passage, and an axially backwardly open and annular groove between the surfaces and of a predetermined radial width in a relaxed condition of the sleeve.  A tightening ring of a radial dimension greater than the width of the groove fits so tightly in the groove as to press the sleeve radially outward against the surface of the passage and inward against the conduit.  The ring is formed at least two similar sector-shaped ring parts having the same radius of curvature as the groove and having ends provided with angularly interfitting formations.

Abstract: ABSTRACT OF THE DISCLOSURE         A seam welding machine capable of producing  a uniform welding bead quality along the seam of cylindrical articles  to  be  welded  such  as  cans  and  the  like.          Commercial AC power is full-wave rectified and then passed through an inverter to produce a relatively high frequency AC  output  current.    The  AC  output  current  is  applied through  a  center-tapped  secondary  transformer   to  a rectifier circuit, and thence through a smoothing circuit composed of a reactor and a capacitor to a pair of rotary electrodes.    A  detector  senses  when  end  portions  of article to be welded are near the electrodes, and controls the AC power source so as to reduce the welding current at the  times when the end portions of  the  articles  to be welded are passing the rotary electrodes.

Abstract: ABSTRACT            In  a  weapons  training   simulator,  laser  radiation  is output via optics  (28)  to  simulate  the  firing  of  a  round.  and  reflected radiation received via a conjugate path to assess the effectiveness of the shot.  In the event of a miss a scan of the target area is required to provide fall of shot information.  The scan is performed by  controlled  movement  of  the  output  faces  of fibre optics (23, 24, 25) flexibly coupling to fixed sources (20, 21. 22) and of the input face of a fibre optic (200) flexibly coupling to a fixed detector  (201).  The problem of the bulk and inertia of prior art system  is improved by the remote location of lasers, drive and control,  which  may  be  conveniently  separated  for  service  or replacement  without  disturbing  the  optically  aligned  input  and output  faces.   A  futher  improvement  is  that  vertically  aligned multiple  sources  may  be  employed  without  undue  weight  penalty, yielding elevation information from a lateral scan.

Abstract: ABSTRACT OF THE DISCLOSURE:            A current limiter for high voltage utilizes the high migration velocity of an arc for rapidly inserting at least one pair of resistive runner rails upon a short-circuit in a circuit.  To be able simultaneously to fulfil the demands for a high energy absorption capacity and sufficient resistance per unit of length of the runner rails,  the runner rails are made of a relatively thin, insulated tape of an electrically conductive material, which is folded and packed to form a solid resistance package. Between the two runner rails in each pair of rails there extend two parallel walls of insulating material, which form between them a narrow gap for the arc. The magnetic field in the gap is reinforced with the aid of a magnetic core and/or current loops.

Abstract: METHOD FOR IMPLEMENTING AN ON-LINE PRESENTATION IN AN INFORMATION PROCESSING SYSTEM                     Abstract A  method is provided for creating on-line presen-tations on a computer display using a compiler, a compressor, and a processor.  The compiler converts control commands in source code format into object code format in order to specify how the information in an on-line presentation is to be presented on the display.  The compiler also creates a file identifying the image data to be used in the presentation.  This file contains the names of the display units de-scribing the image data used to indicate which of the uncompressed image data is to he operated upon by the compressor.  The compressor formats and compresses the displayable picture elements of text and graphic shapes which have been used to create the on-line presentation.  The processor then loads and executes the object code of the control commands with its corresponding picture elements of image data to create the on-line presentation.  The control commands are generated totally separately from the image data.
