Abstract: A device, comprises an electrical circuit, comprising a processor, a memory, and a clock, operable to determine a physiological parameter of a user from a physiological signal; a counter, having a count number decremented by an operation of the electrical circuit to determine the physiological parameter; and a software program, executable by the processor, operable to receive an authorization code, to determine an increment number from the authorization code, and to change the count number by the increment number, wherein the device can be used a greater number of times by the user after receipt of the authorization code.

Abstract: A method of inserting z-axis reinforcing fibers into a multi-layer composite laminate. Layers of material made up of z-axis fiber and y-axis fibers are automatically transported into a z-fiber deposition machine having a housing with upper and lower surfaces. Z-axis apertures are formed in the respective upper ad lower surfaces. An elongated solid rod having a tapered front tip is aligned in close proximity to the aperture in the bottom surface. The rod is first rotated by a motor and then actuated upwardly completely through the thickness of the layer of x-y material by an actuator. A first hollow tube having a z-axis is axially aligned with the aperture in the top surface and a fiber bundle is threaded downwardly through a first hollow tube to a position adjacent its bottom end.

Abstract: A method and apparatus for forming an improved pultruded and clinched Z-axis fiber reinforced composite laminate structure. The upper and lower skins and the core are pulled automatically through tooling where the skin material is wetted-out with resin and the entire composite laminate is preformed in nearly its final thickness. The preformed composite laminate continues to be pulled into an automatic 3-dimensional Z-axis fiber deposition machine that deposits “groupings of fiber filaments” at multiple locations normal to the plane of the composite laminate structure and cuts each individual grouping such that a extension of each “grouping of fiber filaments” remains above the upper skin and below the lower skin. The preformed composite laminate then continues to be pulled into a secondary wet-out station.

Abstract: The present invention relates to a process for producing an optically active aldehyde (first aldehyde) containing a reduced amount of the corresponding enantiomeric aldehyde (second aldehyde) which process comprises: (1) providing an initial solution containing a non-eutectic mixture of the first aldehyde and the second aldehyde, which mixture has a composition in the compositional region where only the first aldehyde crystallizes when its solubility limit in the solution is exceeded, and (2) maintaining the solution at a temperature above the eutectic temperature of the mixture and under conditions such that the solubility limit of the first aldehyde is exceeded so as to form a crystalline first aldehyde containing relatively less of the second aldehyde than was present in the initial solution.

Abstract: A card edge connector for printed circuit boards is disclosed which employs a double-decker design. The connector may have the same length and width as conventional connectors used on Industry Standard Architecture (ISA) personal computers but is deeper. Conventional 8- and 16-bit ISA accessory circuit boards may be plugged into a corresponding socket which is also disclosed herein until they reach a stop upon which they rest, working as they would in an ISA personal computer. 32-bit Extended Industry Standard Architecture accessory circuit boards have a second row of connectors and a notch so they slide farther down into the socket, lining up with a second row of contacts. This design uses less physical space for connectors, allowing more room for logic circuitry on the motherboard.

Abstract: The invention provides an intertube thermal conductance rate limiting device for a nuclear reactor fuel channel having an inner pressure tube and outer calandria tube. The device comprises a wire screen placed in the annular region between the pressure tube and calandria tube which limits the contact area between the two tubes. By reducing the contact area, the screen limits the thermal conductance rate to the calandria tube. This reduces or eliminates the potential for film boiling or "dryout" of the calandria tube.

Abstract: An improved extrusion structure and techniques for obtaining very high extrusion speeds based upon the use of higher extrusion temperatures and resulting increase in critical extrusion rates. Structure is provided for eliminating back flow of the extrudate, for continuously mixing the extrudate just prior to entering the extruding die, and for controlling the temperature of the extrudate at critical locations along the path of flow.

Abstract: A cooling system pressure tester is provided which allows consumers to determine the approximate vent pressure of their automotive cooling system, as well as to check for leaks in the system. The device includes a connecting and restriction element for introducing water into the system and an adjustable pressure relief valve for limiting the maximum pressure.

Abstract: In a regenerator vessel for stripping water from wet glycol, a tray is provided for collecting dry glycol; from that tray the dry glycol flows by gravity only through an indirect heat exchanger into indirect heat exchange relationship with the incoming wet glycol. A process for drying wet gas such as water-containing natural gas includes glycol regeneration with the gravity flow of the dry glycol through heat exchange means.

Abstract: A one-piece club holder for attachment to a vehicle door has a closed-end ring-shaped socket at its lower end and a transversely extending, U-shaped clamp at its upper end connected by a narrow strip having holes therethrough for fasteners to secure it to the inside of the vehicle door. Midway of the ends the strip has a portion widened on an arc to pass partially around the club, the widened portion being progressively widened toward the lower end to pass halfway around the club. The bracket is adapted to be fastened to the inner side of the door at its opening side at an angle of from 30.degree. to 45.degree. from the vertical so that the upper end of the club is available to be grasped for removal immediately when the door is opened.
