Abstract: WRAPAROUND CLOSURE ARTICLE     ABSTRACT     A wraparound closure article comprising a slit tubular body having upstanding rails      extending along the slit is formed by a combination of blow-and compression-moulding. The rails      are formed by compressing a longitudinal edge portion of a parison between two parts of a closed split-mould to form a flange, and the tubular body      is formed integrally with the rails by blowing the remainder of the parison into contact with the closed mould. The flange is then cut to provide the slit of the wraparound closure article and to divide the flange into two discrete rails. The slit extends along the pinch-line     that forms as a result of compressing the edge portion of the parison in the closed mould.

Abstract: IMPROVEMENTS IN CENTRIFUGAL PELLETIZING SYSTEMS                 ABSTRACT OF THE DISCLOSURE             Uniform pellets of thermoplastic material are formed by centrifugally expressing strands of heated ma-terial from orifices on the rim of a hollow rotor and severing the strands with a linearly moving endless blade at a selected radial distance from the rim.  The severed pellets pass in a tangential path through a cooling spray at the entrance to a pellet outlet duct.  The severing blade is mounted on a bracket for movement to and from the severing position and for adjustment radially and circumferentially of the rotor axis.  Two blade assemblies are employed alternately so that blade replacement may be accomplished without interrupting operation.  Downstream from the outlet duct an auxiliary knife-gate is employed adjacent a scrap duct and is movable from a severing posi-tion to a scrap duct closing position.

Abstract: VARIABLE SPEED PRINTING FOR DOT MATRIX PRINTERS                  Abstract of the Disclosure A variable speed printing (VSP) adaptor for a dot matrix printer which includes a monitoring means having a plurality of devices each capable of assuming one of two states.  The monitoring means monitors the state of the pattern data to be printed,  and,  in the preferred embodiment, the monitoring means comprises a counter which is preset with a number equal to the number of column scans with a dot print line.  The pattern data to be printed is scanned in a forward direction, i.e., in the normal printing direction starting at the first print position and the count  in the  counter is decremented one count for each column data scanned.          During the time interval between when this data is latched and the actual hammer actuation, the pattern data is scanned in the backward direction starting at the last print position.  Each time the column data for a backward scan is zero, i.e., no dot to be printed, prior to sensing a non-zero column, the count in the counter is decremented one count. The printing operation continues in the interleaved forward/backward scans until the count in the counter reaches a reference level such as zero. Upon sensing this reference level in the counter, a control signal is generated which indicates that the printing of the dot row is complete and initiates movement of the paper to the next dot row position.  In an alternate embodiment, the monitoring means comprises a random access storage device.

Abstract: ABSTRACT OF THE DISCLOSURE       The manure spreader includes a wheeled, V-shaped body having a longitudinally positioned impeller rotatively carried near the bottom of the V-configuration.  The impeller blades are positioned on a multi-sided body and are arranged in oppositely generated helices to urge the manure both from the rear of the body and from the front of the body toward an outlet gate which is positioned in the body intermediate its ends.  A rotary spinner is carried outwardly of the body in position to receive the effluent from the outlet gate and a suitable drive mechanism is provided to rotate the spinner at many times the rotative speed of the impeller.  The spinner and the impeller are simultaneously rotated by a common drive, which may be a tractor PTO, and an adjustable deflector is provided in effluent path from the spinner to easily vary the spray pattern.

Abstract: ABSTRACT OF DISCLOSURE          In an apparatus for passive leg-exercises comprising a pedal bearing which is supported by a floor stand and a pedal crank with pedals driven by a driving motor, the invention provides that above the floor stand, which forms a lower apparatus section, there is an independent upper section which carries handle bars.          This upper section is connected with the floor stand by a tube of flat cross sectional configuration and is inclined from the vehicle in the direction towards the user.  The knees of the user are maintained relatively apart by smooth walls of the upper section.  The user can operate the apparatus from a wheelchair so that it is possible to treat particularly patients suffering from illnesses such as multiple sclerosis or paralysis.          The pedals are suspended and therefore allow, even where full control function is lost in the patient's feet, an optimal anatomically correct position at all times while the crank is turning.

Abstract: ABSTRACT         This invention relates to a tuner/converter for receiving and con-verting television signals by cable into television signals adapted to channels 2,3 or 4 of the VHF band in the RTMA standard.  The tuner/converter is versatile and can be incorporated into existing converters.  As opposed to such circuits currently in existence which are complicated and costly to manufacture, the design of this invention is an integral module on a single circuit plate which can be more easily and accurately manufactured and thereby provides batter performance characteristics.  The intermediate frequency amplifier block employed in this invention allows for standard electronic components to be in-corporated therein through the use of printed resonant lines.

Abstract: ABSTRACT     Porous polytetrafluoroethylene materials having high strength and coarse microstructure are produced by densifying the materials after removal of lubricant and then stretching.  The term, "coarse," is used to indicate that the nodes are larger, the fibrils are longer, and the effective pore size is larger than conventional materials of the same matrix tensile strength.          Densification can be achieved through the use of such devices as a densification die, a calender machine, or a press.  This invention can be used to produce all kinds of shaped articles.
