The system includes a lightweight panel for releaseable attachment to the opening of a cargo container, a refrigeration unit separate from the lightweight member, and flexible conduits for conducting vapor between the cargo container and the refrigeration unit in a substantially closed looped system.

Abstract: A blind cleaning device in which rollers are mounted on fingers which are designed to be projected between the slats of the venetian blinds. The rollers are retained on the fingers by means of a releasable detent means which is integral with and defines the end of the fingers. The rollers are mounted in a rotatable but interference fit on the fingers.

Abstract: A prone patient positioner is provided which includes about four padded pylon members mounted on a beam or rail structure. The pylon members are positionable along the beams structure so as to provide a padded pylon at each of the patient's forehead, chin, upper chest and pelvic area. The prone patient positioner is strapped to and movable with the patient.

Abstract: A single line pair power control system is disclosed and consists of a reflex module supplying direct current of a first or a second polarity to the control line pair. The polarity of the reflex module reverses in response to a drop in the voltage between the control lines. One or more command modules may be connected between the control lines for short circuiting the two lines to thereby cause polarity reversal of the reflex module. One or more power control relays may be connected to the control lines, such that the relay switch ON for one polarity state of the control lines and are switched off for the opposite polarity of the control lines, thereby controlling power to a load. Also disclosed are an extender module for extending the length of the control lines beyond the length that can be driven by the reflex module, and override circuits for disabling the operation of the command modules, and a special interface which allows control of the reflex module through logic level signals.

Abstract: A stationary dot matrix printer for printing both continuously variable and repetitive information on a moving substrate utilizing a continuously driven endless loop of ink absorbing web material and either a solvent laden wick to wipe the print wires or a composite web having a non ink-absorbing impact layer on the print head side of the web. A shuttle element drives the web reciprocally in a lateral direction to distribute the wear.

Abstract: A disposable sanitary napkin comprising an elongated absorbent pad having two opposite faces extending between two pad ends and two side edges has a reversible bag of substantially impermeable material affixed to one pad face such that the bag may be reversed to wrap and contain the pad after the used pad has been rolled up for hygienic disposal after use.

Abstract: A removable speedbump-cover comprising an elongated laterally arcuate panel which is designed to rest on its elongated edges on the surface of a driveway. Gusset plates extend transversely of the panel on its concave side. The lower edges of the gusset plates are spaced slightly from the surface of the driveway so as not to interfere with the mounting of the panel. The panel is sufficiently flexible to permit the lower edges of the gusset plate to come into contact with the surface under load.

Abstract: An improved telescoping retainer for dental prostheses includes a coping mounted to an abutment tooth and having an endless O-ring groove formed about the outer axial surface of the coping in a plane generally transverse to the coping axis. The coping mates closely with a retainer cavity in the dental prosthesis and has a complementary O-ring groove defined in the retainer surface. A resilient O-ring is fitted over the coping such that the ring cross section is partly received within the coping groove and partly within the retainer groove, thereby forming a resilient interference fit between the dental prosthesis and the coping. A method for making the grooved copings and retainers is disclosed.

Abstract: A product and process for relaxing and softening the fibers in textile fabrics. The product consisting essentially of an alcohol-aqueous admixture including a silicone-glycol copolymer surfactant and/or a fluorinated alkyl ester surfactant together with a quaternary ammonium salt surfactant. The product being preferably applied to the fabric in the form of a very fine mist and in quantities just sufficient to dampen the fabric. The dampened fabric is manipulated so as to form it to the desired configuration and it is maintained in that configuration while it drys.

Abstract: This fish securing device has a relatively small diameter cylindrical axial assembly to which are hinged a number of fish securing arms. A spring loading mechanism contained within the axial assembly urges the hinged arms towards a closed fish securing position by means of an actuating linkage arm associated with each securing arm. A cocking and trip mechanism is actuatable upon tugging on a fish lure connected to one end of the axial assembly for releasing the securing arms from an open cocked position towards their closed position to secure a fish tugging on the lure. The device features an improved, compact, streamlined configuration whereby the spring loading mechanism is contained within the central tubular assembly and wherein the cocking and trippng mechanism and securing arm actuating linkages are disposed in a relatively protected position between the securing arms and the central axial assembly to minimize the possibility of damage or of entanglement with underwater growth, rocks or debris.

Abstract: A combination toothpick dispenser/matchbook is disclosed in comprising a matchbook provided with a cover foldable against an opposite match-carrying portion of the matchbook, the cover having an inside surface, a toothpick dispenser attached to the inside surface, the dispenser including a pocket for receiving lower ends of toothpicks inserted therein, a retainer for holding the intermediate portions of the toothpicks flat against the inner cover surface, and a flap covering the upper ends of the toothpicks, both ends of the toothpick, that being cover for sanitary purposes and security while being readily accessible for individual removal. The combined matchbook/toothpick dispenser is disclosed in two different embodiments and a separate self-contained toothpick dispenser is also disclosed.

Abstract: A stationary dot matrix printer for printing both continuously variable and repetitive information on a moving substrate utilizing a readily replaceable ink applicator for applying ink to a blank foil adjacent to the printing station.

Abstract: A boiler for a heat sensitive working fluid in which there are three systems, first, a stream of hot combustion gas system, second, a heat transfer fluid system and lastly, a heat sensitive working fluid system. The heat transfer fluid is at the interface between the hot combustion gas and the working fluid so as to prevent the formation of hot spots.

Abstract: A carrier material is combined with Tc-99m and the resulting radiolabeled reagent is combined with a known ulcer-specific compound. The resultant agent, because of the ulcer-specific compound, tends to accumulate at the site of an ulcer in the digestive tract. The presence of localized concentrations of Tc-99m in the digestive tract indicates the existence and location of an ulcer. The Tc-99m is detected in the digestive tract by conventional radioimaging procedures.

Abstract: A multi-speed friction drive suitable for propelling cycle vehicles comprises a drive frame attachable to the frame of the cycle, a drive motor mounted to the frame, a gear hub mounted to the drive frame and driven by the motor through a belt drive. A friction roller is formed on the outer shell of the gear hub, which is coupled to the belt drive through a shiftable gear arrangement internal to the gear hub. The cycle is propelled by frictional engagement of the roller with a cycle wheel.

Abstract: A toothbrush to automatically guide the user to simultaneously clean a tooth surface, the cusps, and the gingival sulcus at approximately 45 degrees. The bristle elements are arranged generally in two banks with the free ends of the bristle elements in the first bank extending convergingly with the free ends of the bristle elements in the second bank to provide a V-shaped tooth receiving channel having an acute included angle of from about 10 to 55 degrees. The bristle elements in the respective banks which are closest together, which is at about the apex of the V-shaped tooth receiving channel, extend into contact with one another at the bristle tips to define therebetween a doublet of mutually supported bristle elements. This doublet provides a stiff cleaning element for the nooks and crannies of the cusps of the teeth.
