Abstract: ABSTRACT OF THE DISCLOSURE         A body support member for spacing a body above a sup-porting structure which comprises a sheet of resilient plastic material permanently deformed to produce downwardly disposed, laterally spaced, elongated protuberances distributed over a body support area for engaging the supporting surface, adjacent elongated protuberances being complementary in shape with each one having a plurality of reversed direction portions along its length, the reversed direction portions in adjacent protuberances being in overlapping relation in the plane of the body support area looking in the direction the elongated protuberances ex-tend, whereby the body support area of the member will resist flexing along all lines traversing the body support area.  Where desired, the resiliency of the plastic material of the body sup-port member can be such that the reversed direction portions of the elongated protuberances incorporate an inherent spring-like action under the weight of a supported body to cushion the same.          Ornamental cover material may be applied over the top and/or bottom of the body support member.  The body support member is so designed that it can be vacuum or pressure molded and is there-fore stackable in large numbers for shipment and storage.  The body support member may have joined to the lower portions of the elongated protuberances a second sheet of plastic material which is flat or a second sheet of plastic material which has upwardly disposed elongated protuberances which can be complementary in shape to the elongated protuberances of the body support member joined to the lower portions of the downwardly disposed elongated protuberances of the body support member.

Abstract: ABSTRACT OF THE DISCLOSURE         In cementing a well with a thixotropic cement, such as with the portland cement/CaSO4.?H2O/water slurry described in U.S. 3,563,313, an effective means for con-trolling fluid loss from the slurry is to precede the slurry with a fluid comprising water, a water soluble alkali metal compound capable of releasing a multivalent metal cation to react with the soluble silicate to form a pumpable gel, and a water dispersible cellulose com-pound and an inert particulate which together impart fluid loss control to the fluid.  Optionally, the fluid may contain one or more of:  a chelating agent for poly-valent metal cations; a weighting material; a material to minimize lost circulation, and a salt to stabilize fresh water sensitive sandstones and shales, e.g., those having a high clay content.

Abstract: Abstract of the Disclosure A dry wiping system for use in a mechanized car wash establishment in which an automobile moves along a defined path comprises a series of strips of water absorbent material suspended from a carrier above the path of the automobile. The carrier, which moves the strips so that they wipe across the wet exterior surfaces of the automobile, is guided along a circuit which causes the strips to be carried across the path of the automobile at an angle such that the strips have a substantial component of motion in a direction opposite the motion of the automobile substantially throughout each traverse of the path. Preferably, the circuit of motion is of trapezoidal form and the system also includes a pair of power driven wringer rollers positioned to receive the strips after they have passed across the automobile to dewster the strips prior to their next excursion across the automobile.

Abstract: SPEERS, Samuel F.          TOY ILLUMINATING ASSEMBLY            Abstract of the Disclosure A toy assembly is presented wherein board means is adapted to receive a plurality of separate light trans-mitting pegs.  The board means generally forms the bottom wall of an enclosure in turn provided with a generally planar cover such that the pegs and other includable portions of the toy may be conveniently stored therein.          The inner surface of the cover is provided with a light reflective surface that is upwardly disposed when the cover has been removed and attached to the toy so as to serve as a support for the board means.  The board means is disposed at an acute angular relationship to the re-flective surface such that light incidence upon said surface is reflected to those peg portions disposed in the board means.  This construction eliminates the need of an included light source with the toy as well as forming of a self-contained storage and transport container.

Abstract: PUBLIC KEY CRYPTOGRAPHIC APPARATUS AND METHOD     Abstract of the Disclosure A cryptographic system transmits a computationally secure cryptogram that is generated from a publicly known transformation of the message sent by the transmitter; the cryptogram is again transformed by the authorized receiver using a secret reciprocal transformation to reproduce the message sent.  The authorized receiver's transformation is known only by the authorized receiver and is used to generate the transmitter's transformation that is made publicly known.  The publicly known transformation uses operations that are easily performed but extremely difficult to invert.          It is infeasible for an unauthorized receiver to invert the publicly known transformation or duplicate the authorized receiver's secret transformation to obtain the message sent.

Granted: 1982-06-01
Abstract: ABSTRACT OF THE DISCLOSURE     A process is provided herein for preparing an ethylene-?-olefin copolymer having a density of 0.850 to 0.945.  In the process, ethylene and 1 to 40 mol% thereof of an ?-olefin having 5 to 18 carbon atoms are co-polymerized in a substantially solvent-free vapour phase condition and in the presence of a catalyst comprising a solid substance and an organo-aluminum  compound,  in which the solid substance contains magnesium and at least one of  titanium and vanadium.   The copolymer so produced is superior in transparency, appearance and gloss, and its flexibility and elasticity are excellent both at low temperatures and at room temperatures.  Despite such an excellent flexibility, the resulting polymer exhibits equal or even superior strength to that of ordinary polyolefins.   The copolymer is very superior in weathering- and chemicals-resistance, as well as having super-ior electrical characteristics, e g , dielectric loss, break-down voltage and resistivity.   The copolymer exhibits very superior characteristics with respect to resistance to impact and to environmental stress cracking.   The copolymer can be formed into films, sheets, hollow containers, electric wires and various other products by known forming methods, e.g., extrusion molding, blow molding, injection molding, press forming and vacuum forming. Because of its excellent strength, elongation, transparency, anti-blocking property, heat-sealing property and flexibility, it provides good films. Because of its low hexane extract, it can be safely used as a food packing film.   Because of its transparency, stiffness and resistance to environ-mental stress cracking, it is also suited to blow molding.  Because of its excellent electrical characteristics and easy application to extrusion molding, it can be used as an insulator for electric wires.

Abstract: ABSTRACT OF THE DISCLOSURE A method of treating molten cast iron is disclosed, wherein a sand mold Is formed with a gating system, a plurality of casting cavities, and treating chambers all located symmetrically about a parting plane of said mold. The treating chamber is interposed in the gating system and is configured to receive a predetermined sized module of treating alloy arranged to fit snuggly within a predetermined size lower portion of said chamber  The module is comprised of fiberboard folded into a closed container condition and filled with granular treating alloy particularly comprised of nominally 5% MgFeSi.  The molten metal reacts progressively from the top of said module to the bottom portion thereo as the molten metal flows over and therepast.  The fiberboard enclosed granules constitute a convenient, economical and improved mode for treating molten cast iron particularly when nodularization is required, and particularly with restrictions such as those imposed by the shall mold technique wherein the centerline of the reaction chamber coincides with the parting line of the mold.  Due to differential ferrostatic head heights during mold filling there is a radical variation in flow rate through the treatment chamber. These conditions necessitate the use of a granular material with a tendency to more immediately react with the molten metal than a cast to-shape or briquetted material.  The granular material is enclosed in the module of sufficient integrity to hold a cubicle configuration extendinq across the plating plane, allowing the mold halves to be closed.
