Abstract: A computer mouse having cord management and cord connector storage and protection features. The feature for storing, deploying and retracting the device's cord in, from and into its case is an internal capstan, principally a reel, that is spring-biased to return to its retracted position. A pawl and ratchet assembly is used to fix or stabilize the cord at points of its extension; alternatively, a snubbing feature is shown that obviates the pawl and ratchet assembly. For securing the connector, thereby protecting it during transport, there is included in the case design a pocket or port into which the connector is retracted.

Abstract: A patch antenna is provided with one or more tuning strips spaced therefrom and RF switches to connect or block RF currents therebetween. When a conducting path for RF current is connected between the tuning strips and the patch, the tuning strips increase the effective length of the patch and lower the antenna's resonant frequency, thereby allowing the antenna to be frequency tuned electrically over a relatively broadband of frequencies. If the tuning strips are connected to the patch in other than a symmetrical pattern, the antenna pattern of the antenna can be changed. A feed network couples RF to the antenna and includes two hybrid couplers, one for providing the correct amplitude and phase of excitation at the feed probes, and the second for effectively dissipating reflected power due to antenna impedance mismatch.

Abstract: A torque tool for tightening a nut or fastener of a work piece to a pre-determined torque level is presented. The torque tool includes a split housing having mounted therein a gear train for driving a hinged gear, a releasably mounted reaction tool and an electronic circuit for indicating an amount of torque placed upon the fastener. A power input is, planar with and interconnected to the gear train. The gear train includes a worm and a worm gear. The hinged gear meshes with the worm gear and includes a socket for engaging the fastener. The reaction tool has an open end or jaw for receiving a portion of the work piece and an opposite end which, when mounted, is disposed within a tubular recess of the housing. This structure provides for the retention of reaction forces within the housing of the torque tool itself. The electronic circuit for indicating torque is employed to measure the reaction forces via a strain gauge and display such forces to an operator of the tool.

Abstract: A torque wrench is presented which has dual output/reaction modes, with the input and output operating in the same direction in both modes. In one mode, a stationary reaction adapter is outside of an inner rotating torque adapter; in the second mode, a stationary reaction adapter is inside of an outer rotation torque adapter. Torque levels are measured by strain gages mounted on a single reaction arm and are read out digitally.

Abstract: A torquing apparatus is presented having a split ring which engages a member to which a torque load is to be applied. The split ring is loaded into gripping engagement with the member during a forward (torque input) operation; and the split ring is released from the member during a return operation to achieve repeated operation without removing the apparatus from the member to be torqued.

Abstract: A torquing tool is provided which is adapted to tighten threaded connections located in hard to reach places to precise torque values. The torquing tool comprises a housing having a pair of spaced arms pivotably attached thereto. Each arm include a series of idler gears which terminate at a reversible output gear or drive shaft. The housing includes a gearing mechanism which drives a selector gear. The selector gear pivots between a first position which will actuate the idler gears and output gear in the first arm and a second position which will actuate the idler gears and output gear in a second arm. During use, the output gears of the torquing tool are mounted on a pair of spaced nuts; with the arms being pivoted to adjust for differing bolt centers. Next, a handle extending from the housing is actuated to move the selector gear between the first or second position to acutate the gears in either the first or second arms.

Abstract: A torquing apparatus is presented having a split ring which engages a member to which a torque load is to be applied. The split ring is initially loaded to establish a threshold friction load between the split ring and the member. The split ring is loaded into gripping engagement with the member during a forward (torque input) operation; and the split ring is released from the member during a return operation to achieve repeated operation without removing the apparatus from the member to be torqued.

Abstract: A wrench is presented which includes a power cylinder having a piston rod extending therethrough. An anchor or reaction assembly comprising an anchoring ring and attached anchor rod is adjustably attached to the piston rod to permit connection of the anchoring ring to a nut spaced from the nut to be turned. A wrench assembly comprising a preferably arcuate lever arm with a ratchet assembly is pivotably connected to the power cylinder. The wrench incorporates a ratchet pawl which engages a drive mechanism. A control lever can disengage the pawl from the drive mechanism, and a latch mechanism retains the control lever and pawl in a disengaged position until released.

Abstract: A low profile power wrench is provided which is useful both for general application and for easy accesses to bolts and nuts in cramped or hard to reach places. The drive of the wrench and the reaction system are in tension, thereby resulting in important advantages for the wrench. The wrench includes a power cylinder having a piston rod extending therethrough. An anchor or reaction assembly comprising an anchoring ring and attached anchor rod is adjustably (i.e., threadably) attached to the piston rod to permit connection of the anchoring ring to a nut spaced from the nut to be turned. A wrench assembly comprising a preferably arcuate lever arm with a ratchet assembly is pivotably connected to the power cylinder. Operating fluid (hydraulic or pneumatic) is delivered sequentially to the power cylinder through first and second inlet/outlet openings.

Abstract: The external sleeve of a slip brake in a torque wrench with a pair of clutches in series is provided with a spiral groove which houses lubricant. "O" rings at opposite ends of the external sleeve cooperate with an internal sleeve to seal in the lubricant. The slip brake of the present invention incorporates an internal split ring or drum which is adjustable to set the desired bias load of the slip brake. However, the split ring or drum is encased in a very thin steel sleeve which is attached, as by soldering, to the split ring. The outer surface of the thin steel sleeve abutts the inner surface of the outer ring and serves as the brake drum. Although the split ring is encased in a thin steel sleeve, the sleeve is thin enough (from about 0.025" to 0.030" thick) so that this sleeve will stretch when the split ring is expanded to increase the bias load on the slip brake.

Abstract: A combined torque wrench and geared wrench which includes a ratchet mechanism, so that it can be operated in either a clockwise or a counter-clockwise output direction and so that a nut can be run down by ratcheting if necessary (due to space limitation) or desireable. The body of the wrench is relatively small so it can be operated by hand for quick run down. Provision is made for incorporation of an elongated handle which can be used for quick run down, pre-torquing, and/or a reaction bar. The wrench also incorporates a gear train for torque multiplication, and the gear train can be crank actuated by either of two inputs which are accessible at opposite sides of the body of the wrench, thus making the wrench accessible for crank input even though one side may be in quarters which are too close for use of the crank. The two inputs on opposite sides of the wrench also serves the purpose of allowing drive input on the side opposed to the side which must be supported against a reaction surface.

Abstract: A self-aligning post is presented to direct and/or balance a load being transmitted. The post has a semispherical end section split from the remaining main cylindrical portion of the post whereby misalignment of the main cylindrical portion is compensated by the split end section. The post is further provided with means for retaining the cylindrical portion in contact with the semispherical end section and for preventing the split end section from slipping from a socket. Preferably, the retaining means is an annular skirt disposed along the flat perimeter of the semispherical end section wherein the cylindrical portion of the post will bear against the skirt during misalignment and thereby prevent slippage.

Abstract: Described herein is a radiation upset threshold detector apparatus for measuring the output from a circuit that is operating in a radiation environment to determine when the radiation upset threshold is exceeded for the circuit.

Abstract: A torque producing tool of compact design may have its driven output member displaced from the tool body through use of an easily attachable extension drive. By providing a plurality of different extension drives the maximum output torque of the tool may be varied in stepwise fashion.

Abstract: A torque wrench is presented having a pair of clutches in series. One clutch is a one way clutch, preferably reversible, which transmits the input force in one direction during torquing operations; and the second clutch provides friction restraint against movement in the opposite direction. When desired, force applied to the wrench in the opposite direction overcomes the friction clutches to release the wrench from the work.
