Abstract: A pressure head (10) for contacting a workpiece (230) through relative movement in the vertical Z-direction includes a frame (20), a horn (100) for contacting the workpiece (230) and a gimbal (40) connected to the frame (20). The gimbal (40) supports the horn (100) such that the horn (100) can rotate about orthogonal X and Y rotation axes and can translate in the Z-direction relative to the frame (20). Three adjustment arms (170) movably connected to the frame (20) each apply a force on the horn (100) at points determining a plane for rotating the horn (100) about the X-axis or the Y-axis to a fixed position before contact with the workpiece (230). The adjustment arms (170) also provide electrical connection to electrical devices (136, 138) on the horn (100). A movable contact arm (190) connected to the frame (20) also contacts the horn (100) for providing an electrical connection.

The gimbal (40) has only a single outer torsion member (50) and supports the horn (100) such that the horn (100) can rotate about orthogonal X and Y rotation axes and can translate in the Z-direction relative to frame (20). Each gimbal (40) having only a single outer torsion member (50) allows a pair of gimbals (40) to support horns (100) in close proximity for operation on two proximal work areas.

Abstract: A tool for dismounting a bicycle pedal crankarm from a crankshaft. A bicycle crankshaft has a mounting end and the crankarm has a crank mount having a bore therethrough having on one end a socket mounted on the crankshaft mounting end. The tool includes a puller and a handle. The puller comprises a housing having a column bore therein and having a proximal end and a distal end having screw threads adapted for mating attachment with internal screw threads in the crank mount bore. A column comprised of a piston and a rolling bearing is contained in the column bore and reciprocally slidable therein. The handle is pivotally connected to the puller and pivotable 180.degree. between an attachment position and a dismount position. Pivotal movement of the handle between an attachment position and a dismount position when the housing is attached to the crankarm mount moves a cam that moves the column against the crankshaft mounting end to dismount the crankarm.

Abstract: A human powered vehicle comprises a frame supporting a rider in a substantially horizontal position, a driven wheel rotatably mounted on the frame, a drive gear for driving the driven wheel, left and right pedals mounted on the frame, the pedals reciprocally traveling in a substantially horizontal, rectilinear path, and a transmission connecting each pedal with the driven wheel for converting the rectilinear motion of the pedals into rotary motion for propelling the driven wheel. In a first exemplary embodiment, each pedal includes a rack and each transmission includes a pinion gear engaged with the rack. In a second exemplary embodiment, a drive belt connects each pedal and to the drive gear. The pedals are connected by that drive belt or another belt such that the pedals move simultaneously but in opposite directions In a third exemplary embodiment, each pedal is connected by a connecting rod to crank arm on the crank of a conventional crank driven bicycle.

Abstract: A test interface between a two sided circuit board to be tested and a test controller and it generally includes an upper and a lower test fixture each including personality plates having bores for simultaneously guiding translation pins into contact with test nodes on the circuit board under test. Circuit board tooling bores are mounted on tooling pins in the personality plates. The tooling pins tapered to a diameter slightly larger than the diameter of the circuit board tooling bores. One or both personality plates are mounted such that they may move responsive to forces exerted on the tooling pins because of nonalignment such that the forces tend to equalize. This results in better overall alignment.

Abstract: An efficiency indicator for a separation system, such as a water filter, wherein a first volume of fluid is exposed, under a first pressure, to a separation medium and a second volume of fluid is recovered therefrom, under a second, lesser pressure. The indicator comprises a housing including an aperture and a biased piston rod in a tube driven between a first position and a second spaced-apart position by the differential between said first and second pressures when said second pressure represents an undesired loss of medium separating efficiency. The piston rod has a first reflective colored coating at one location on said rod and a second reflective colored coating at a second location. A sphere of optical transparent material is mounted so as to project through the aperture of the housing.

Abstract: A cooling device for an electronic component, such as a computer processor, generally comprises a heat sink and a plurality of fans. The fans are redundant in that sufficient cooling is supplied should one fan fail. The fans are independently powered and are inspectable and independently replaceable in situ without un-powering the other fan or the processor. The heat sink includes a base plate having a bottom for surface contact with the processor, a front row of fins projecting upward from the front of the base plate and a rear row of fins projecting upward from the rear of the base plate. A plurality of fans are mounted substantially within a cavity between fan rows. Each fan blows a flow of air such that the flow impinges on the base plate.
