Abstract: OVER-CURRENT PROTECTIVE APPARATUS FOR A POWER CIRCUIT      Abstract of the Disclosure A solid state relay structure for use with different alter-nating current motors having a range of full load current ratings and service factor ratings.  The relay includes a rec-tangular housing and bores extending through the housing through which conductors to the motor are passed.  The rear end of the housing is spaced from the panel on which the relay is mounted so the conductors may be looped through the bores when portions of the looped conductors are passed in the space between the rear end of the relay and the panel.  The solid state components of the relay are encapsulated in the interior of the housing and are connected to switches, terminals, and a light emitting diode located at the front end of the housing.  The switches are provided so the circuits within the relay may be pro-grammed for use with motors having different overload current and service factor ratings, to operate in a manual or automatic reset mode of operation and be readily reset when the relay is programmed to operate in the manual reset mode.  One of the -switches acts as a test switch and causes the relay to trip independently of the current to the motor.  The relay, when tripped, will cause the diode to visually indicate that the re-lay has tripped.  The terminals and operating and test instruc-tions also located at the front end of the relay provide a con-venient arrangement for wiring the relay in its control circuit and provide the information required to program the relay for the characteristics of the motor it is to protect and the se-quence of steps to be taken to test the operability of the relay.

Abstract: DISPLAY RANGE MARKER PROCESSOR                Abstract of the Disclosure A variable range marker processing device for use with a PPI radar with digitized video displayed in non-real time.          The position of the range marker is initially operator deter-mined by rotation of a knob mechanically linked to an optically encoded disc.  Optical sensors produce a digital output indica-tive of tile disc rotation angle and range mark position as a distance from the center of the radar display screen.  A counter is preset with the digital output at the start of each sweep and decremented once each range cell until a count of zero is reached at which time an unblanking pulse is produced.  A numeric display of range is produced by dividing the number of range cells to the range mark by the range setting, scaling according to chosen units of measure, and displaying the result with a LED display, the computations being performed by a processor controlled by a permanently programmed memory.  The range mark stays on target as the range scale is changed.  The amount of movement of the range mark for a given amount of con-trol rotation is independent of range scale.

Abstract: ABSTRACT OF THE DISCLOSURE    Apparatus for separating particulate matter from a flowing fluid which, for example, may be sand entrained in a flowing stream of oil and gas, comprises an assembly including a plurality of small diameter tubular elements, the walls of which have a selected permeability to said fluid.  The tubular elements are held with their axes parallel between a pair of headers by suitable tension means.  The interior of the tubes are connected to at least one plenum and to a well tubing.  When this assembly is inserted into a well producing oil and gas which carries sand, the sand will be deposited against the outer walls of the tubular elements since the grain diameters are greater than the size of the openings in the walls of the tubular elements.  The fluid flows through the openings in the wall of the tubular element, into the plenum and then through the well tubing to the surface of the well.  By using suitable headers at each end, a plurality of these assemblies can be connected in series.  This apparatus is equally applicable to the filtering of any type of particular matter from any type of fluid.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an improved method for separ-ating plastic in film form from paper in a paper-plastic mix during the processing of urban solid waste.  The invention comprises a two step separation process.  Initial separation is effected by the action of rotating rollers which contact the paper-plastic mixture while it is being transported along a conveyor belt.  Final separation occurs when the plastic film which has become entangled in the rollers is taken therefrom by a fan driven cyclone.  This invention improves the separation process by skewing the axis of rotation of the separating rollers with respect to the velocity vector of the waste being transported along the conveyor belt.  Once the plastic film has become entangled in the rods on the surface of the rollers, it passes successively from one roller to the next until it is carried past the edge of the main conveyor belt and deposited on an  adjacent conveyor belt.  The outlined improvements effect a reduction in plant manufacturing and operating costs and result in a more efficient separation process.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates generally to relatively large irrigation water sprinklers  of the arm driven type which include a reversing mechanism for part-circle watering.  When a relatively large-diameter nozzle is used in sprinklers of this type, the reverse drive arm moves the sprinkler in a reverse direction with a very large accelerating force. The reverse movement can be so rapid that there is a significant risk of injury to anyone standing nearby, as well as a likelihood of increased wear and possible damage to the sprinkler it-self.   Of course, movement of the reverse drive arm can be adjusted to allow a smaller portion of the reverse deflector spoon to enter the water stream, thereby re-ducing the reverse accelerating force and obviating the problem.  However, when a nozzle of different size is again installed, readjustment is always necessary.  Prior art sprinklers do not have means associated with its reversing mechanism for automatically compensating for nozzles  of different sizes.  The present invention satisfies this need by providing an improved water sprink-ler of the arm driven type which has a reverse drive arm movable into the water stream emerging from a replace-able nozzle, to provide rapid reverse rotation of the sprinkler.  The improvement lies in a novel nozzle structure which limits movement of the reverse drive arm by an amount dependent upon the nozzle size, thereby resulting in substantially the same reversing force regardless  of nozzle size.
