Abstract: A self-drilling anchor is provided which includes an elongated tapered plastic body and anchor assembly. The body has an external helical threaded portion, a central clear bore for receiving the anchoring assembly, two diametrically opposed break-away slotted portions, and an axial driving flange concentrically positioned relative to the tapered body first end. The flange has inner and outer walls, a central clear aperture for receiving a screw driver, and at least two diametrically opposed notches for receiving a bladed driver for drilling the tapered body into a hollow wall. The anchoring assembly is centrally received in the clear bore, and includes an externally threaded screw, a collar, and at least two diametrically opposed separable arms. The collar is internally threaded for receiving the screw. The separable arms have spring loaded ends and pointed ends. The spring loaded ends are pivotally attached to the collar.

Abstract: A raised floor access panel is provided which includes a substantially flat panel having an upper load supporting surface and a lower surface to be supported on a plurality of pedestal support members each adjacent to a corner of the panel, and at least one panel lifter having a top wall and two side walls, the side walls slidably extending through a first and second slots in a plate rigidly attached to the lower surface for vertical travel of the top wall and side walls upwardly, through a generally rectangular panel recess.

Abstract: A rear bicycle suspension has a main frame including a seat riser tube, a down tube, head tube, and a bottom bracket housing having left and right sides, a guide arm and a shock mount attached to the main frame, a pair of swing arm assemblies each one in pivotal attachment on either side of the main frame at a first pivot point and to a bell crank at a second pivot point, the swing arms in rearward extension form the first and second pivot points to at least one rear swing arm attachment point, and further including a lever arm connected between the first and the second pivot points, a guide arm having first and second ends wherein the first end in pivotal attachment to the guide arm bracket at a fifth pivot point and the second end extends upward and rearward from the fifth pivot point, wherein the bell crank is pivotally connected between the lever arms at the second pivot point and to the guide arm at a third pivot point, a shock absorbing member in pivotal attachment at one end to the shock mount and at a

Abstract: A portable, hand held exhaust pipe cutter having an air motor to drive a cutting wheel arranged parallel to a drive shaft of the air motor by an angle head gearing device. The cutter makes straight cross-sectional cuts through cylinders by using a feed lever pivotally attached to the air motor that engages the cylinders to be cut and guides them into engagement with the cutting wheel. The feed lever on an opposing end includes a handle that extends along the air motor so that a user can grip both the control lever of the air motor and the handle of the feed lever simultaneously with a single hand.

Abstract: A processing system for dynamic analysis of hydraulic performance in a computerized fire sprinkler system model is provided to aid sprinkler designers in auto-peaking the system when at least one of the elements are in a flowing hydraulic state, the system comprising storing in a first memory means a drawing view of a fire sprinkler system, the drawing comprised of a plurality of changeable interengageable system elements, representational of an actual construction, for selective assembly together, the elements having distinctive dimensional and operational properties including an open, closed or automatic flow, providing a remote area boundary for dynamic movement through the view, the remote area in operative connection with the automatic property, finding any one of the elements having an open-flow property, locating the boundary in the view, finding any one of the elements within the boundary having an automatic flow property, calculating a hydraulic result for at least one element using the open or autom

Abstract: An omni-directional wheel is provided which includes a frame having an upper portion for affixing the frame to an under-side of a weight bearing surface, at least two side walls, and a central cavity defined by the side walls for receiving at least one spherical wheel, at least two wheel bearings connected in axial alignment to the side walls for rotation of the wheel about a fixed axis, at least two wheel seats each having one side in axial connection to the wheel bearings and an opposite conical face wherein the conical faces are disposed in opposite axial alignment for mounting the wheel between the faces and a force of static friction is exerted relative to the conical faces and the wheel when the wheel is rotating about the fixed axis and a force of kinetic friction is exerted relative to the conical faces and the wheel when the wheel is rotating about an axis perpendicular to the fixed axis, and an upper load bearing connected to the frame which bias against an upper surface of the wheel.

Abstract: A bed harness for a pet, has a ventral strap, collar strap, and a girth strap, the ventral strap connected between the collar and the girth straps, a stay having a first and second end, the first end attached to the ventral strap at a point in close proximity to the girth strap, a bed having an upper surface, a lower surface, and a central vertical shaft through the surfaces for receiving the second end through the surfaces, and a device for stopping the second end from releasing back through the shaft, the stopping device attached near the second end of the stay at a distance from the first end which allows the pet to sit or stand on, but not move from, the upper surface of the bed. In this manner, the weight of the pet restrains the animal to the desired location of the bed.
