Abstract: The data transfer system operates by collecting data from game machines and transferring said data to a smart card type data transfer unit containing memory, addressing, control, and protection circuitry. Depending on the level of capability desired, the card may or may not have microprocessor and encryption circuitry. Various embodiments include systems that store data regarding cash flow, security violations, machine malfunctions, and volume of play attributable to an individual player, and transfer that data to a smart card for use in monitoring machine performance and determining the eligibility of a particular player to receive premiums as a play incentive. Additionally, either in concert with one or more of the above features or not the system can allow a player card to be used in lieu of cash to play game machines. In this instance, the player card can either be used as a pre-paid debit card, or as a credit card in which case money is collected from the player after he has played.

Abstract: A hair band is arranged for securement of a hair grouping in surrounding relationship with a hair band, including a central rigid core of memory retentent material selectively receiving a sheath thereabout to accommodate hair groupings of various sizes within the band structure. A modification of the invention includes the sheath formed with a tubular chamber filled with a temperature sensitive liquid crystal to effect visual color change in response to ambient temperature. A further hair band organization utilizes a clasp member, wherein the clasp member includes a flexible arcuate top plate spaced from a bottom latch plate, with the latch plate including a medial friction plate equivalent to the hair band formed with bifurcated end and a central body mounting a resilient sleeve thereabout to provide frictional engagement between the medial friction plate and the bottom latch plate when in an assembled configuration.

Abstract: Two substantially purified larval T. solium antigens found circulating in the cerebrospinal fluid of patients infected with T. solium, having molecular weights of 190 KD and 230 KD, are disclosed. These antigens, alone or in combination, may be used to diagnose or to follow the course of neurocysticercosis, caused by T. solium infection.

Abstract: Immunological methods are disclosed for diagnosing active human neurocysticercosis, including a serum test and a cerebrospinal fluid test. The serum test involves detecting an antibody in serum which recognizes at least one of three particular antigens isolated from Taenia solium larvae. The cerebrospinal fluid test involves detecting an antigen or antigens of larval origin, preferably by an ELISA technique.

Abstract: A test socket for integrated circuit packages has a body member carrying a plurality of pairs of opposed contacts on either side of a circuit package receiving cavity which seats a depressible spring loaded platform. When a circuit package is inserted, the contacts make electrical contact with the circuit package terminals and are deflected outwardly as the package is pressed downwardly. The force exerted by the deflected contacts and the terminals is sufficient to provide good electrical contact and to overcome the biasing force on the platform to retain the circuit package in the socket. The circuit package is released by a tool which has a cavity to receive the body member and cam elements to deflect the contacts and permit the spring-loaded platform to move upwardly and release the circuit package.

Abstract: A crane with an anti-skewing device comprising a platform suspended under a bridge deck by two end truck assemblies supported by runways on a bridge. Each end truck assembly includes two sets of trolleys and an upper load bar interconnects the two sets of trolleys. A lower load bar is suspended from the upper load bar by a kingpin for rotation about a vertical axis. Hinge tubes support the platform on the suspension assembly for pivotal movement in a direction lengthwise of the platform. Each end truck assembly is driven by a variable speed motor. As skewing occurs a mechanical sensing mechanism senses relative movement between lower load bar and the upper load bar and provides a signal to an electronic circuit causing one or both of the motors associated with the end truck assembly on which the sensing mechanism is mounted to increase or decrease the speed of the motor and thereby correct the skew.

Abstract: Isocyanate-derived foams are prepared from an isocyanate, catalyst, blowing agent, foam stabilizing surfactant and at least two active hydrogen-containing compounds wherein one of the active hydrogen-containing compounds is an alkylene oxide polymer having an equivalent of at least 300 and being composed of at least about 10 weight percent, based on a total weight of the polymerized alkylene oxide in the polymer, of a polymerized ethylene oxide.

Abstract: This invention is for an inexpensive flexible heater material (heat pad) for food heating, medical compresses and the like. The heat pad is a composite material consisting of a supercorroding metallic alloy powder dispersed throughout a porous polyethylene matrix. The supercorroding alloy material consists of a powdered alloy of magnesium and iron which is produced by high energy powder metallurgical milling techniques. Pressureless sintering of a mixture of the supercorroding alloy powders with UHMW polyethylene powder results in the formation of a flexible porous matrix material with active ingredients therein that are readily activated with a suitable electrolyte fluid.

Abstract: A process is disclosed for burning hydrocarbons in the vapors emitted from contaminated metallic scrap in a remelt furnace having a molten bath therein. The furnace comprises a charging chamber and a heating chamber separated by a wall. The wall is provided with at least one lower opening and at least one upper opening through which the chambers are in communication above and below the level of molten metal. Scrap is charged into the charging chamber where molten metal ablatively melts the charge. Oil and other surface contaminants evolving from the charge are drawn through the upper opening in the wall into the heating chamber by maintaining a pressure in the heating chamber less than, or negative in relation to, the pressure in the charging chamber. The hydrocarbon vapors burn in the heating chamber and contribute heat of combustion. Controlling the level of pressure differential between the heating chamber and the charging chamber facilitates substantial benefits in efficiency and economy.

Abstract: A method and means for the repair of severed peripheral nerves utilizing a porous, thin walled, bridge conduit or tube and an applicator instrument therefor. The instrument is connected to a vacuum source and has means for supporting the tube in the region of the transverse hole therein. When supported by the instrument the interior of the tube is operatively connected to the vacuum source through the transverse hole and a pressure differential is created between the interior of the tube and the ambient atmosphere by means of the vacuum source. This pressure differential is used to draw one end of the severed nerve into one end of the tube and then the other end of the severed nerve into the other end of the tube, the nerve ends being in abutment within the tube. Additional means may be provided to maintain the nerve ends in abutment within the tube when required and means may also be provided facilitating removal of the tube upon repair of the nerve if desired.
