Abstract: ABSTRACT OF THE DISCLOSURE         The fibrous structure of a non-woven mat is disrupted by an apparatus comprising at least one roll which has one or more upraised ribs in a chevron pattern extending helically around the roll.  In processing, the mat passes under tension over at least a portion of at least one chevron roll and preferably over two chevron rolls which may or may not be intermeshing.  Thereafter, the mat may be crushed or crimped by being fed through to intermeshing third and fourth chevron rolls.  Additional rolls may be supplied to exert tension.  The mat which exits from the apparatus has a disrupted fibrous structure and is a superior skeleton within a structure such as a polymeric foam board.

Abstract: Process and Apparatus for Processing Plastic and Polymeric Materials ABSTRACT OF THE DISCLOSURE:    Novel and improved processes and apparatus for processing particulate plastic or polymeric materials which can be converted to the liquid state. Essentially, the process and apparatus involve feeding a particulate material to an annular processing passage for melting and controlled processing. The annular processing passage is provided by two elements. One is a rotatable element carrying at least one processing channel.          The other element is stationary and provides a complementary, coaxial surface arranged with the channel to provide the enclosed processing passage. Also associated with the stationary element are an inlet for feeding material to the passage, an outlet for discharging material and a member or members extending into the processing channel providing a material restraining surface between the inlet and outlet and a material collecting end wall surface for the passage. Rotation of the rotatable element provides a coaction between the rotatable element and material restraining surface providing member which establishes relative movement between the rotating inner channel wall surfaces and the restrained particulate material.          Because of the relative movement, only liquid (melted) material in contact with the rotating channel walls is dragged forward to the material collecting end wall surface for controlled processing and discharge.

Abstract: ELECTRICAL CONNECTOR FOR COAXIAL CABLE            Abstract of the Disclosure An electrical connector assembly for terminating a coaxial cable of  the type having a central electrical conductor separated from a braid-type outer electrical conductor by an insulation layer with a jacket around the outer conductor, said conductor assembly comprising a rear nut, a forward body, and a medial clamp member.  The clamp member has a body with a central aperture extending there-through from front to rear for receiving the insulation layer and central conductor therein and a tapering frusto-conical outer surface of a smaller diameter at the rear of the clamp.  The frusto-conical surface is provided with a helical groove (or portions thereof)  which are machined into the body to provide a series of undercuts or depres-sions.  The connector assembly is assembled over the co-axial cable with the nut slipped over the cable, and the clamp member inserted between the braid and the insulation layer.   The clamp member is rotated in the direction of the helical grooves to progressively draw the clamp member within the braid of the cable until the entire frusto-conical portion is within the braid.   An edge of each helical groove provides a corner surface which engages the braid,  securing  it and providing  a  resistence to un-desirable axial movement of the clamp member away from (out of) the cable.  The body and the nut are provided with interfitting threads to secure the entire assembly to-gether, with the clamp member captivated therebetween in proper position.

Abstract: ABSTRACT OF THE DISCLOSURE     A transmission system is provided for differential speed control.  An endless, resilient member in the form of an endless belt is driven by an input pulley.  The speed differential is derived by using the input speed taken from one effective radius of the resilient element and picking the output speed from a different effective radius of the resilient element, with the different effec-tive radii being variably selectable.  Thus an output pulley has its periphery in contact with the resilient member and a control carriage coupled to the resilient member is operative to vary the curvature of the resilient member with respect to the periphery of the output pulley.          In this manner, the neutral axis of the resilient member is varied to control the speed of the surface of the resilient member that is contacting the periphery of the output pulley.

Abstract: APPARATUS AND METHOD FOR CONTROLLING FOCUS           IN A RECORDING SYSTEM            ABSTRACT OF THE DISCLOSURE           A control system for maintaining proper focus of a radiant recording or writing beam, such as a laser beam, with respect to a recording surface, by measure-ment of the duty cycle of an oscillatory information-carrying  signal  recorded  from  the  recording  surface immediately after  recording.   The  system  includes a photodetector for detecting a reading beam used to recover the  recorded  information,  a focusing lens movable with respect to the recording surface to focus the writing and reading beams, a dither oscillator to generate a dither signal employed to move the focusing lens in an oscillatory manner, a duty cycle detector to provide a signal indicative of the duty cycle of the information-carrying  signal  recovered  by the  reading beam, and a multiplier for comparing the phases of the duty cycle signal and the dither oscillator signal, and thereby providing a correction signal indicative of the magnitude and  polarity focus error.   This control system provides fine focus control, and is utilized in conjunction with a coarse focus control comprising a focus  detector,  differential  amplifier  and  feedback path to the movable focusing lens.   In addition, the signal from the duty cycle detector can be coupled to maintain the power of the writing beam at an optimum level and to maintain the duty cycle at a constant level, such as fifty percent.

Abstract: NOZZLE AND METHOD FOR GENERATING FOAM     ABSTRACT OF THE DISCLOSURE           A nozzle and method for generating foam is disclosed which includes a nozzle body, a nozzle inlet, an orifice, a gas inlet, an impingement pin and a nozzle outlet.  The nozzle body has upstream and downstream ends and an inner wall defining a passage within the nozzle body.  The nozzle inlet at the upstream end of the nozzle body permits introduction of a liquid foam producing agent into the passage.  The foam producing agent then passes through the orifice, thereby forming a stream.  This stream is directed past the gas inlets in the nozzle body to aspirate gas into the passage. The stream then impinges against the impingement pin which is disposed transversely across the passage.  At least the upstream half of the cross-section of the impingement pin is annular so that the impingement pin disrupts the flow of the stream and splits it into secondary streams.  These secondary streams pass out-wardly on each side of the impingement pin and diverge with respect to each other prior to being deflected inwardly off the inner wall of the nozzle body.  The nozzle outlet comprises a transverse slot disposed parallel to the impingement pin so that a thorough mixing between the gas and foam producing agent is effected prior to discharge through the nozzle outlet as foam.

Abstract: ABSTRACT OF THE INVENTION   A document 14 to be read is illuminated by light source 10 and imaged by optics 16 onto a single 19 integrated defector array made up of a number of photosensitive linear arrays 20, 22, 24, 26. Each linear detector is read out to provide a line scan of the document. The document is then translated across the line, or its image is caused to translate to achieve the same result, and each linear array is read out again, resulting in raster input scanning of the document. The detector array consists of three or more linear arrays fabricated on the same integrated detector array 19 and located one above the other and horizontally aligned. Each one of the three arrays 20, 22, 24 is covered with a color filter 21, 23, 25, so that it only sees one color light (i.e., red, green, or blue). By reading the three arrays out in parallel, all three colors on the document are read simultaneously. The only difference between the three images (besides color), is that at any point in time, each one is at a different height on the document. This difference is eliminated by simply remembering which line each image is on and correctly formatting the data which reaches a printing device or is stored on a memory.
