    摘要： A circuit is provided that can provide, in a single package, a circuit to monitor a sensing element which uses a variable resistor. The circuit (also known as a signal conditioning circuit) may contain resistor input terminals to which a reference set resistor and a resistive sensor can be attached. A reference voltage signal can be applied to both terminals. There are also a circuit for sensing the resulting current flowing through both the set resistor and the resistive sensor. The difference of the currents flowing through each element can then be monitored as being indicative of the difference in resistance between the set resistor and the resistive sensor. The current difference signal can be used to generate a voltage difference signal indicative of the difference in resistance between the set resistor and the resistive sensor. The signal conditioning circuit may be used to adjust the temperature of various devices.

    摘要： A method according to the invention analyzes the generation of graphical images by cataloging primitives by the states in which they are rendered. It permits, for example, for analysis of the execution of a computer instruction sequence, e.g., a computer program, of the type that generates a graphical image from a plurality of primitives. The method includes the steps of identifying primitives rendered by the instruction sequence, along with the composite graphical states in which those primitives are rendered. The method further includes generating an output signal characterizing the program, i.e., via cataloging the primitives by the states in which they were rendered.

    摘要： A clock which is intended for use in soda fountains, restaurants, bars and other places of business as an advertising display, and which may be illuminated. The clock comprises a rectangular-shaped rigid frame, a translucent thin plastic panel constituting a clock face which is mounted in the frame and which extends across the area circumscribed by the frame, the thin panel being held in place by integral lugs which fit into slots in the frame, and a transparent plastic cover mounted on the frame in front of the clock face. In one embodiment the drive motor for the clock is mounted on the rear side of the plastic panel. In a second embodiment the drive motor, together with an illumination source for the translucent panel, are mounted in a housing which is supported on the rear side of the frame behind the thin plastic panel.

    摘要： Apparatus for blocking fluid flow in a well casing where the well is out of control due to blowout, fire or casing leaks. A shell comprised of two hingedly connected mating parts is mounted on the casing so as to enclose a portion thereof in a sealed manner. A metal cutting saw blade in the shell is provided with power means to reciprocate it and move it into the casing whereby the blade cuts through the casing. The width of the blade is greater than the casing diameter so that upon completion of the cut the blade blocks the fluid flow. This permits a shut off valve or other control means to be installed in the casing above the shell after which the saw can be withdrawn and the shell removed for re-use.

    摘要： An aircraft air distribution system includes a base and first and second arrays of nozzle air transfer ports in the base. An adjustable flow plate is positioned over the nozzle air transfer ports. A compressible member is located between the base and the adjustable flow plate and between the first and second arrays. First and second air ejector regions are located, respectively, on the sides of the compressible member between the base and the adjustable flow plate to connect to the first and second arrays, and direct air from the first and second arrays from the sides of the base. Fasteners moveably connect the adjustable flow plate to the base and are adjustable to change a size of different sections of the first and second air ejector regions to change an amount of airflow originating from the different sections of these regions.
