Abstract: ABSTRACT OF THE DISCLOSURE It is known to prepare thermoplastic resins having particular properties by cross-linking polymers or monomers having known properties. This procedure has the disadvantage that it is very difficult to make a polymer which has tailor made properties.  The present invention seeks to overcome the drawback by providing a thermoplastic resin composition having excellent resistance to weather  and impact, which comprises a binary graft-copolymer  of a rubber component consisting essentially of an ethylene-propylene rubber and an aromatic vinyl compound or a ternary graft-copolymer of a rubber component consisting essentially of an ethylene-propylene rubber, an aromatic vinyl compound and a vinyl cyanide compound; 0.5 to 10% by weight of liquid paraffin having a specific gravity from about 0.860 to about 0.905; and an antioxidant, an ultraviolet absorber or a mixture thereof.    The addition of the liquid paraffin has a synergistic effect on the resin enhancing its impact and weather resistance. Such resins are suitable for use in products subject to heavy exposure and wear.

Abstract: ABSTRACT OF THE DISCLOSURE          This invention relates to a method of controlling curvature of regions in a shaped thermoplastic sheet.  More particularly, it relates to producing bent glass sheets on a mass production basis by passing a series of glass sheets through a heated furnace and then bending each successive sheet to shape by press bending.  Temperature measurements are made on a selected portion or portions of selected heat-softened sheets to provide a profile of reference temperatures. After the sheet is shaped and allowed to cool, the radius of curvature errors of selected regions in each of said portions are determined.  The magnitude of these errors and the deviation of said reference temperatures from target temperatures determined for said portions determines the nature of one or more changes that are made in one or more parameters of the mass production operation.          In a preferred specific embodiment, a composite temperature is determined for each portion from formulae based on reference temperatures of the selected portions.  A selected composite temperature, one that provides a desired radius of curvature error in the regions of each selected portion, is determined for each of the portions of the sheet. A target temperature for each of the portions is determined from the selected composite temperature of the respective portions to give a desired radius of curvature error in the regions.  According to a specific preferred embodiment of this invention, the parameter of the operation that is changed is the heat pattern in the furnace, which is altered in response to the data derived from reference temperature readings and radius of curvature errors, determined with calculated target temperatures and desired values of radius of curvature errors, respectively, to cause subsequent heat-softened sheets to be heated in such a manner that the temperatures at the different portions approximate the target temperatures calculated from the selected composite temperatures.

Abstract: ABSTRACT OF THE DISCLOSURE           A high energy ignition adapter circuit prevents trig-gering of the counter by a false indication of the opening of the points due to a waveform peculiar to low coil signals pro-duced in vehicles using high energy ignition systems.  A timing light delay circuit having a variable delay is incorporated with the timing light to produce the delayed signal proportional to distributor advance, the delay being adjustable within two selectable ranges.  By measuring and displaying the computed dwell for each cylinder in sequence, distributor mechanical wear associated with shaft bearings and drive gears may be detected.          Power contribution and dynamic relative compression for each cylinder may be measured by using the counter to measure the time that the points are open, and the time that the points are closed, for each cylinder in sequence, and displaying the measurements.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved heterogenous specific binding assay method which employs a substance having reactant activity, i.e., a reactant, as a labeling substance in the detection of a ligand in a liquid medium.  The method is carried out using reagent means which comprises, as its labeled constituent, a conjugate formed of a specific binding substance coupled to the reactant.  The reactant advantageously is an enzymatic reactant such as an enzyme substrate or coenzyme.  The activity of the conjugated reactant as a constituent of a predetermined reaction system is utilized as means for monitoring the extent of binding of the labeled constituent in conventional heterogenous specific binding assay schemes. The presence of a ligand in a liquid medium may be determined following conventional competitive binding manipulative techniques.  After the necessary separation of the bound-and free-phases resulting in the specific binding reaction system, the extent of binding of the labeled constituent is determined by contacting either phase with the necessary materials to form the predetermined monitoring reaction system in which the labeling substance is active and assess-ing reactant activity therein.

Abstract: ABSTRACT OF THE DISCLOSURE            The disclosure relates to the provision of improved and advantageous facilities for the on-line adjustment of the length of the compressive shrinking zone in a so called two roll compactor.  The compactor shoe is supported at each end, by a pair of primary levers arranged to pivot around the axis of a feeding roll.  By movement of the primary levers, the tip of the compacting shoe, forming the upstream end of the compressive shrinking zone, is movable toward or away from a roller nip, formed by opposed feeding and retarding rollers and constituting the downstream end of the compressive shrinking zone.  A simple, reliable and precise adjustment feature is provided, enabling the operator to easily and quickly effect precision adjustment of the position of the shoe tip, while the equipment is in full speed operation, so that the processing of materials in the compactor may be optimized.  The physical arrangement of the new adjustment feature is such that, in addition to its significant functional advantages, it is readily adaptable to the structure of standard forms of equipment in the field, for on-site upgrading of machine performance.

Abstract: METHOD AND APPARATUS FOR PROCESSING      METAL MATERIAL INTO BALES            ABSTRACT OF THE DISCLOSURE         A frame having a baling chamber formed therein and a feed hopper member pivotally mounted adjacent the chamber for introducing a car body or similar article partially into the baling chamber.  A cover member is pivotally mounted adjacent the other side of the baling chamber and has a front edge constructed as a cutting edge. The cover member when pivoted to its open position permits the introduction of the car body into the baling chamber by tilting the feed hopper member.  The cover member, when pivoted to its closed position after the car body is partially introduced into the baling chamber, will partially crush and bend the car at approximately the middle portion thereof so that substantially one-half of the car body will be inside the baling chamber and the other half will protrude out of the baling chamber through the space adjacent the front edge of the cover member.  The portion of the car body protruding out of the baling chamber is sheared off and a portion of the car body remaining in the chamber is then partially crushed by moving the head of a first compression ram into the baling chamber.  The ram head has a cutting edge thereon which cooperates with the cutting edge on the cover member to produce the desired shearing action there-between.  The partially compressed material in the baling chamber is then further compressed into a completed bale by moving the head of a second compression ram into the baling chamber underneath the cover.  The travel path of the second compression head is at right angles to the travel path of the first compression head.  The completed bale is removed from the baling chamber by actuating a gate member to expose an opening in the bottom of the baling chamber to thereby permit the completed bale to drop out of the chamber through the opening by gravity.
