Title: Exercise projectile, more especially of the discarding sabot type
Inventor: SIE SWAN L
IPC: F42B8/14
Filed: 1978-05-10
Granted: 1981-05-19
Abstract: ABSTRACT An exercise projectile of the discarding sabot type and having a projectile body consisting of at least two parts which, after traversing a predetermined trajectory, are separated from one another and are provided with first and second connecting means for keeping these parts interconnected prior to firing and during the predetermined trajectory, respectively, and with disconnecting means for rendering the connecting means inoperative at least at or near the end of the predetermined trajectory.  The first con-necting means comprise means cooperating with the sabot, like collars engaging in grooves of the sabot.  The second connecting means are of the type acti-vated by the firing of the projectile, e.g. of pneumatic type, like gas pressure interlocking means which, during the predetermined trajectory, are kept under a gas pressure derived from the firing gas pressure and are reduced during the predetermined trajectory by suitable means, like leakage ducts.

Abstract: ABSTRACT Synthetic filaments composed of homopolymers and co-polymers of poly(alkylene oxalates) are absorbable in animal tis-sue with minimal adverse tissue reaction.  Polymers prepared by reacting a dialkyl oxalate with an alkylene diol are melt spun and drawn to obtain oriented fibers having good tensile properties and a high level of flexibility and softness.  The filaments are particularly useful in the preparation of surgical prosthesis comprising woven or knitted fabrics and meshes.  Other absorbable surgical devices including films and molded items may also be pre-pared from the disclosed polymer.

Abstract: IN THE UNITED STATES PATENT AND TRADEMARK OFFICE Application for Letters Patent TO ALL WHOM IT MAY CONCERN:          BE IT KNOWN THAT I, ARNOLD WEINER, a citizen of the United States of America, residing at 2507 Avenue X, Brooklyn, County of Kings, New York, have invented certain new and useful improvements in WAFER AND FASTENER FOR USE IN ELECTRONIC THEFT DETECTION SYSTEM.                    ABSTRACT OF DISCLOSURE          A wafer construction which includes an expansive, generally flat plastic member formed with a spiral groove in which an elongated electrical conductor is held in the shape of a coil.  The plastic member is also formed with a recess in which a capacitor is contained.  The capacitor is connected to both ends of the conductor to form a resonant electrical circuit.  A hardened steel reinforcing element is also embedded in the wafer around the wafer circuits to protect them against severing.  A tack-like fastener element has a concave head which telescopes over a dome-like projection on the wafer to provide a tamper resistant fastening assembly when the tack shank is inserted into an opening in the wafer.

Abstract: ABSTRACT OF THE DISCLOSURE A method is described for using ball sealers as a diverting agent when treating a subterranean formation penetrated by a well provided with casing having perforations at a plurality of levels.  Ball sealers sized to plug a perforation, a first fluid having a density greater than the ball sealers and a second fluid less dense than the ball sealers are introduced into the casing concurrently or in any order.  The amount of the first fluid introduced should be sufficient to fill the lower portion of the casing to a level between the lower perforations to be plugged and the upper perforations to be left open to fluid flow.  Once the ball sealers are disposed below the upper perforations, treating fluid is injected into the casing to cause a flow of the second fluid through the lower perforations to carry the ball sealers down the casing to plug the lower perforations and to cause fluid flow through the upper perforation which the ball sealers did not plug.

Abstract: METHOD OF SELECTING OPERATION OF A FLUID-BED REACTOR AND APPARATUS FOR DOING SO                ABSTRACT OF THE DISCLOSURE A method is disclosed for using a pendulum viscometer having damped torsional oscillations, in a laboratory catalytic fluid-bed reactor, to monitor a propensity to stick which is exhibited by certain supported catalysts. A fluid-bed of such catalysts has been found to become suddenly more sticky just before a point at which a change in pressure drop across the fluid-bed can be measured due to a process "upset". At this point ("the inversion point"), the upset is usually irremediable. The method includes correlating data on catalyst stickiness from alaboratory reactor operating at atmospheric pressure, with an expected level of catalyst stickiness in a commercial reactor operating at elevated pressure. A pendulum viscometer and related auxiliary apparatus is disclosed for magnetically and electrically measuring and recording the rate at which the pendulum's torsional oscillations are damped. Frequent measurements are made during normal operation of the fluid-bed to determine its stickiness (as evidenced by the rate at which the pendulum's torsional oscillations are damped) relative to the stickiness at the inversion point. Operation of the fluid-bed under conditions for which measured rates of damping are predeterminedly lower than the rate nearthe inversion point, assures operation of the fluid-bed reactor at maximum efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE A        container packaging material for use in six pack can wraps, six pack bottle carriers, twelve pack carriers, etc, comprising a composite of a paper material laminated to a plastic film.  The plastic film provides tear resistance to the composite, so that paper material may be used which has a tear resistance less than that of other  packaging paper materials.  The reduced tear resistance allows the use of paper having a lower caliper, basis weight, and, therefore, cost than conventional     container packaging material.  Natural kraft paper and recycled paper of 12-16 point caliper are preferred for use with the present composite.  The plastic film may be .25-2 milk thick and is preferably formed of polyethylene terphthalate,  polyethylene, polyvinylchloride, poly-propylene, or cellophane.  The preferred films are transparent and permit reverse printing on their inner surface to provide abrasion resistant decoration visible through the film.  Adhesives are used to bond the film to the paper and are selected to be compatible with the film used.  The film may be metallized to produce a foil effect or may be strengthened by radiation treatment.

Abstract: SAUSAGE CASING AUTOMATIC CLOSING SYSTEM                ABSTRACT OF THE DISCLOSURE         This relates to apparatus for effecting the closing of one end of a shirred casing strand.  A strand is to be automatically presented to a previously developed closer in alignment therewith and under a preselected pressure.  A transfer device is provided for receiving a doffed strand, transferring the strand transversely and then moving the strand longitudinally so that an end of the strand  engages the closer.  A gripping mechanism is provided which includes a pair of jaws having opposing clamp elements of a generally V-shape or angle cross section.  The two jaws are simultan-eously movable either together or apart and are urged apart by compression springs.  A fluid cylinder actuated linkage urges the jaws towards closed positions.  By varying the closing force, the clamp members can be first moved to a pre-set spacing providing a receptacle into which a doffed strand of a predetermined size may be readily slid.  Then by increas-ing the the pressure of the cylinder, the strand may he suf-ficiently tightly gripped to prevent relative movement during the closing operation.  The closer members are separated to release a closed strand at the end of the closing operation. By varying the pressure to the cylinder in the receptacle forming stage of the clamping members, the size of the re-ceptacle may be adjusted in accordance with variations in size of casing strands to be handled.  A control cystem for the automatic operation of the transfer device in conjunction with the closing device is provided.
