Abstract: ABSTRACT OF THE DISCLOSURE A signalling circuit including an electrical to acoustic transducer which is sequentially energized by a pulsatile ringing source includes a potentiometer in series between the source and transducer.  The potentiometer is continually decreased in resistance as source pulsations continue to that each successive acoustic output is of increased intensity.  The wiper of the potentiometer is a needle of a meter movement and the fixed resistance of the potentiometer as arcuate and positioned in place of a meter scale.  A passive quasi-integrator circuit is coupled between the source and the input to the meter movement for pro-ducing a generally increasing signal for advancing the wiper along the resistance.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for discharging cinders from an incin-erator has an upwardly open intake pit having horizontally spaced front and rear walls. A water-filled trough is provided below this intake pit and has an upwardly concave floor and defines an upward-ly extending outlet for cinders which have been quenched after they have dropped down in the pit into the water in the trough. A stepped plunger has a front face slidable in an arcuate path along the floor of the trough between a retracted position relatively close to the front wall defining the pit and an advanced position relatively far from the front wall. This plunger also has an upper surface on which is provided a step having a face which lies in back of the front wall in the retracted position of the plunger and between the walls in the advanced position. Thus as the plunger is advanced from the retracted to the advanced position the step pushes large objects against the rear wall of the pit and compresses these large objects.          In addition, this step is inclined so as to exert a downward compon-ent of force on material in the pit and press it against the floor of the trough.

Abstract: A METHOD AND APPARATUS FOR FORM REMOVAL FROM CONTOUR COMPRESSED          IMAGE DATA          Abstract of the Disclosure An apparatus for removing form (background) information from an image for data compression; and for adding the form information during reconstruction of the image.          Each object in an image is compressed by contour following of the exterior and interior borders of the object, and encoded in chain link form.  Each object in the image as it is compressed is correlated with the appropriate object in the form image by comparing the encoded objects with the already stored encoded objects of the form.  If there is a match, the image object which matches the form is deleted from the compressed image.  Since the order in which the objects are encountered is known, it is only necessary to correlate each image object with at most a single form object.  The correlation includes comparing the starting points of the contour information, the perimeter of the object (the length of its border chain) and the object area.          The comparisons are made within a predetermined acceptable tolerance.  If the variable image data overlaps some of the form image data, the object is retained in the compressed image.  During reconstruction of the image, the form and image data are combined using a technique similar to logical OR operation.

Abstract: ABSTRACT OF THE DISCLOSURE     A dump truck having a telescoping container body which is initially telescoped to a reduced length to discharge a portion of the load and thereafter elevated to discharge the remainder of the load in the manner of a conventional dump truck.

The drive mechanism for driving the front and back section relative to one another consists of a rack mounted on the front section and a reciprocating drive means mounted on the truck.  A pawl is mounted on the drive mechanism and engages the rack to selectively push or pull the front section as required.  The length of the stroke of the drive mechanism is substantially shorter than the total length of movement of the sections between the extended and retracted positions thereof.

Abstract: METHODS AND APPARATUS FOR SEPARATING PARTICLES USING A MAGNETIC BARRIER          Abstract of the Disclosure A flowable mixture of particles is separated in accordance with the magnetic susceptibilities of the particles by feeding the mixture into a magnetic field in such a manner that the mixture is urged by a non-magnetic force, e.g., gravity, towards the locus at which the magnetic energy gradient H.theta.H/.theta.X of the field is at a maximum.  The magnetic energy gradient defines a magnetic barrier along the locus of its maximum magnitude which exerts a magnetic force on the particles in opposition to the non-magnetic feeding force.          Particles having a magnetic susceptibility lower than that value at which the force exerted by the magnetic barrier balances the non-magnetic feeding force pass through the barrier, whereas particles of greater magnetic susceptibility are prevented from crossing from one side of the barrier to the other side and may therefore be recovered separately from the less susceptible particles.  Continuous separations may be carried out by giving the mixture a velocity component lengthwise of the barrier such that particles deflected by the barrier will move therealong to a collection point.  The magnitude of the maximum magnetic energy gradient may be varied along the length of the barrier or plural barriers of different strengths may be provided in succession to provide for progressive separation of the mixture into fractions of different magnetic susceptibilities. Naturally non-magnetic, but conductive, particles may be separated by employing superimposed a.c. and d.c. magnetic fields, the d.c. field establishing the magnetic barrier and the a.c. field inducing magnetism in the conductive particles.  Also, particles may be suspended in a fluid and separated along the magnetic barrier in accordance with the relative values of the magnetic susceptibility and density of the particles and fluid, respectively.
