Abstract: Memories coupled to a gaming terminal, are reprogrammed by a method and apparatus which includes identification, negotiation, downloading and verification information from an external information source to a gaming terminal. Hardware devices are used to identify gaming terminals or components.

Abstract: Photometric apparatus and method for determining the absorbance ratio, in a sample, of two different wavelength lights. A first light is given a reference intensity and is passed through the sample. A second light is passed through the sample and its intensity is varied so that the intensity of the second light that has passed through the sample is equal to the intensity of the first light that has passed through the sample. When these intensities are equal, the intensity of the second light is detected in a state wherein it has not passed through the sample, resulting in an equivalent to the ratio of the absorbance in the sample of the second light and the first light.

Abstract: Process and apparatus for weighing material being collected. In the illustrative embodiment, plasma that has been separated from whole blood is collected. The tare weight is sensed and the weight of the material being collected is sensed. Pulses are provided in frequency proportion to the sensed weight. The tare weight pulses are counted and stored. A net weight counter is set with a predetermined count corresponding to the maximum amount of plasma to be collected. A measure weight signal reverses the tare weight count with the net weight counter being inhibited until the tare weight count reversal has been completed. Once the tare weight count reversal is completed, the net weight counter is operative to count the sensed weight pulses. A completion signal is provided when the predetermined count has been decremented to zero.

Abstract: A phlebotomy needle assembly is provided which permits an anticoagulant to be mixed with whole blood immediately adjacent the cannula through which the whole blood is drawn, to prevent coagulation. A blood-anticoagulant mixing device has a blood inlet for coupling to the cannula, an anticoagulant solution inlet for coupling to a source of anticoagulant and a blood-anticoagulant mixture outlet for coupling to outlet tubing. The blood inlet and the anticoagulant inlet are generally coaxial and the mixture outlet is axially offset with respect to the inlets. The blood inlet defines a mixing chamber and a passage communicates with the mixing chamber and the mixing outlet for providing an outlet flow path through the mixing device for the blood-anticoagulant mixture.

Abstract: An internally threaded dispensing closure for an externally threaded pharmaceutical container having a pour lip. The top surface of the closure defines a first opening surrounded by an upwardly extending port having a membrane therewithin. The spike of an administration set or the like may be inserted into the port to pierce the membrane. The top surface of the closure also defines a second opening having a hydrophobic filter communicating with the air above the top portion and also below the top portion. A gasket is carried by the underside of the top portion for sealing engagement with the pour lip of the container.

Abstract: A membrane diffusion device, such as a membrane oxygenator, is disclosed which comprises a stack of flat membrane wall pairs and flat membrane supports in alternating, interleaving relation. The casing includes a pair of opposed sidewalls that are substantially parallel to flat sides of the stack, and a pair of substantially vertical crimps are formed on each of the sidewalls to provide external compression on the end portions of the stack.

Abstract: Centrifugal processing apparatus in which a processing chamber is rotatably mounted with respect to a stationary base. An umbilical cable segment comprising polyester elastomer tubing is fixed at one end substantially along the axis of the processing chamber at one side thereof, with the other end of the cable segment being attached substantially on the axis in rotationally locked engagement to the processing chamber. In a preferred embodiment, the polyester elastomer is HYTREL.RTM. polyester elastomer.

Abstract: A container closure is provided with internal threads which compensate for variations in the external threads of a container neck onto which the container closure is to be threaded. The container closure threads extend inwardly toward the central axis of the closure and, in the illustrative embodiment, define an angle of 30 degrees with respect to the central axis. The closure thread tapers inwardly as it extends toward the central axis and is generally flexible but is sufficiently rigid to prevent the lower thread from contacting an immediately higher thread during flexing of the threads.

Abstract: A closure system is provided for a threaded container. A threaded closure cap has an annular skirt which engages a resilient gasket that is stretched over the bottle neck. The resilient gasket overlies a cap support flange which extends from the neck. Downward axial movement of the cap with respect to the container provides a vertical compressive force against the resilient gasket by the cap skirt. A heat shrinkable outer member surrounds the closure cap and provides a tamperproof seal with respect to the container.

Abstract: A thermoplastic pharmaceutical solution container includes a neck portion having at least one port through the neck portion. A thermoplastic port protector or closure covers the port and defines a frangible section. The closure has a length to diameter ratio providing good mechanical advantage leverage to rupture the frangible section when the closure is pushed sideways. A seal is formed with the closure by forcing a die heated above the melting point of the plastic material into the neck portion, removing a portion of the port protector and forming a depression. The frangible section is formed in the vertical side wall of the depression.

Abstract: There is provided an improved means and method for attaching a flexible tube to a container of the type having a stub tube port with an end of the tube fitted over the stub port. The attaching means includes a resilient ring tightly fitted over the tube end and a retainer cap fitted over the ring and bonded to the container.

Abstract: An injection site is provided in the illustrative embodiment, in which a first inlet (to which a parenteral fluid conduit is connected) and a second inlet (adapted to receive injected medication) are parallelly located on one end of a main body portion. An outlet is located on the opposite end of the main body portion, with the second inlet and the outlet being substantially coaxial. The main body portion defines a single chamber that communicates with the inlets and outlets and is constructed to provide unobstructed flow of the parenteral liquid and medication to the outlet. The chamber is of a length that aids in preventing the medication that is injected from dropping through air.
