Abstract: A device for motivating a user of an exercise machine while working out indoors. The device includes an exercise machine, a display connected to the exercise machine, a processor, and a sensor. The processor dynamically creates a workout in response to initialization information. The workout includes a plurality of segments, wherein a segment of the plurality of segments satisfies one or more requirements of the workout. The processor selects one or more video clips that correspond to the segment of the plurality of segments. The sensor communicates information relating to the user to the processor.

Abstract: An exercise machine can include a motivating and instructional user interface or display. The interface can include a virtual coach or other encouraging stimulus to provide key motivation for users of indoor exercise machines.

Abstract: A multiple opening sleeve valve is provided with a gate movable to control flow or pressure without the need for axial movement of a component through a pressure-containing seal. A gate actuator can include a drive rod and nut coupled to a gate substantially internal to the valve housing without the need for grease or similar external lubrication. The valve can provide for relatively high in-line gate-moving force, a reduction in force or torque requirements for operation, increased ease of wear-part replacement and decreased overall valve length, compared to previous valve configurations of comparable size or capacity.

Abstract: A dual chamber orifice fitting comprising a first chamber maintained in fluid communication with a pipeline, a fluid flowing in the pipeline passing through the first chamber; a second chamber selectively maintained in fluid communication with the first chamber; a sealing member selectively rotatable from a first position wherein the sealing member seals the first chamber from the second chamber, and a second position wherein the sealing member permits the first chamber to be placed in fluid communication with the second chamber.

Abstract: A nonconductive holster for use with an electrical meter is disclosed. The nonconductive holster comprises a protective guard for preventing a person who is using the electrical meter from coming into contact with any exposed power sources being measured with the electrical meter. The nonconductive holster is fabricated of a nonconductive resilient material which provides the electrical meter with a protective coating in the event that the electrical meter is accidentally dropped or inadvertently struck.

Abstract: There is provided by the present invention a speed changing apparatus having a housing mounting a plurality of inwardly directed, circumferentially disposed teeth, preferably in the form of a ring gear. The housing has a hub that rotatably receives at least a first shaft that in turn eccentrically mounts a plurality of elongate follower arms. Each follower ann is mounted at one end to the shaft with the other end having at least one tooth configured to engage the circumferentially disposed teeth. The housing further includes a base plate that is rigidly attached to the second shaft. Rotary motion is transferred between the first shaft and a second rotatable member by apparatus that includes a base pin that is rigidly attached to the base plate, an arm pin rigidly attached to a follower ann and a linking ann pivotally attached at opposite ends to the base pin and the arm pin. The second rotatable member may be a second shaft, the housing, or the base plate.

Abstract: There is provided by the present invention a mechanical drive system for driving first and second screw conveyors from a single power source. This system includes a primary drive providing power to the first conveyor from the power source and a secondary drive that includes a pair of gear boxes and that supplies power to the second conveyor from the primary drive.

Abstract: A multi-mode signal measurement system provides at least True RMS and Average RMS signal measurement modes in one system in response to a measurement mode selection made by an operator. The system controls the processing of the input signal by a selected signal measurement unit according to the operator selected signal measurement mode. After signal processing is complete, a display unit displays a value of the measurement of the input signal according to the selected measurement mode. Other measurement modes providing peak value and resistance measurement readings may also be provided.

Abstract: A solid state semiconductor power switch for controlling the application of AC power to a load wherein the power switch employs momentary ON/OFF switches for activating the power switch, and wherein additional circuit means is provided to preserve the ON/OFF condition or state of the power switch during a power-down situation such that upon restoration of the AC power the power switch can be caused to assume the same ON or OFF state it was in just prior to the power-down situation.

Abstract: A self-closing invisible hinge for returning a door to its closed position rom its open position including a self-closing structure in which the closing force can be selectively adjusted externally at the hinge and in which the self-closing structure is compact.

Abstract: A drywall frame compression anchor assembly for use with a sectional metal frame to be mounted in an opening of a wall comprises a restraining bracket having a pair of space support legs and a jamb anchor. The jamb anchor includes a hat section havng a generally U-shaped center portion and a pair of opositely extending wings projecting therefrom. The jamb anchor is moveably mounted between the supports of the spaced support legs to engage the surface of the opening.

Abstract: A low voltage switch without moving elements, uses a triac power switching element in series with the AC load. A flip-flop circuit provides latching operation for On and Off functions. The triac is isolated from low-voltage actuating circuitry by an optoisolator which draws power from a step down transformer. The transformer also isolates the AC line from the manual switch circuits. A metal case is heat sink for the triac switching element. A threaded nipple, an integral portion of the casing, can be inserted through plug openings in standard electrical junction boxes to form a continuous heat flow path from the triac into the juncture box.

Abstract: An apparatus for supportably elevating and lowering material handling apparatus having an elongate member includes two arms radiating upwardly from a base. A lower undercarriage arm is pivotably attached to the elongate member, and the lift arm is attached to a roller support which moves along a rail on the elongate member. The roller support and attached lift arm arm moved by a winch-drawn cable. At least one pair of spaced support sheaves is mounted on the elongate member, and the cable passes under the sheaves. At least one riser post extends upwardly from the base and is attached to the lower undercarriage arm so that it intersects the cable between the spaced support sheaves. A sheave mounted on the riser arm intersects and supports the cable when the elongate member is lowered. As the elongate member is lowered, the riser post supports an increasing portion of the downward load.

Abstract: An apparatus for mixing animal feeds and the like comprises a rotor having two opposing end assemblies connected by a center shaft for rotation within a mixer box. A flighted outer auger is mounted in the terminal portion of each set of corresponding radial arms of each end assembly, parallel to the center shaft. Each outer auger is rotated by drive means within the first hollow rotor end assembly, powered by a high speed drive shaft, and the entire apparatus is rotated by a low speed drive shaft. The drive shafts extend from opposing end assemblies and are coaxial to the center shaft. An optional center auger or optional intermediately spaced augers, parallel to the center shaft, are rotated by drive means within the second end assembly, driven by one or more outer augers.
