Abstract: A stationary power tool extension table includes a transparent support plate for positioning against a first side of a built-in table on a stationary power tool. Side plates are connected to an edge of the support plate for positioning against adjacent sides of the built-in table. The support plate is hinged to a frame with an open top and an open bottom. Height adjustable legs are attached to the frame for positioning the support plate level with the built-in table. Slide connectors on the frame and the side plates connect the side plates to the support plate, and enable the side plates to slide horizontally against the sides of the built-in table. A removable tray is supported within the frame by a flange around the bottom of the frame. When the tray is removed, a light may be positioned under the support plate to illuminate a work piece from below.

Abstract: The present cutter is comprised of a plate for attaching to the top of a conventional hammer tacker. A notch at the front end of the plate is for engaging a raised head at the front of the hammer tacker. A belt clip projecting from the rear end of the plate is angled away from the hammer tacker for clipping to a belt. A side extension is arranged on the plate to one side of the notch. A shallow groove is arranged on the bottom surface of the side extension, and a blade is positioned in the groove. A thumb screw attached to the blade is positioned through a slot in the side extension. The blade is movable along the groove for extension or retraction relative to the front end of the plate. When extended, the blade is angled to one side of the hammer tacker.

Abstract: A runoff drain filter is comprised of a tray for being supported inside a runoff drain. A plurality of separately removable cartridges are supported by the tray and aligned with holes in the tray. Each cartridge is comprised of a bucket and an insert. The insert is comprised of a central overflow tube centered in the bucket by a vented annular top plate and an annular bottom plate. Runoff pouring into the tray is directed into each bucket through the vented annular top plate. The runoff is filtered by a perforated tube which is part of the central overflow tube before it is discharged through an open bottom of the central overflow tube. Debris and contaminants are collected in the buckets. The total capacity of the filter is divided among the separately removable cartridges to enable a filled cartridge to be more easily lifted by an average person.

Abstract: The present stick is comprised of first and second tubes telescopically connected together. The tubes are biased away from each other by a coaxial coil spring. A shaft is positioned within the first tube, and is biased outwardly from an outer end of the first tube by another coaxial coil spring. A cam is attached to an inner end of the shaft. Holes are arranged on the first tube adjacent the cam. Balls are positioned inside the first tube between the cam and the holes. Detents are arranged along the second tube. When the shaft is released, the balls are forced outwardly through the holes and into detents which are aligned with the holes to lock the first and second tubes together. When the shaft is depressed, the balls are retracted by the cam away from the detents and allow the first and second tubes to telescope.

The storage container is comprised of a plurality of parallel storage tubes, a cap, and a lock nut. The filled punch is pushed into the storage tubes for encapsulation, and cap is secured against the open end of the storage container by the lock nut. The material samples are ejected from the storage container with an extraction tool with prongs attached to the press. Prongs on the extraction tool are inserted into the punch through breakable ends of the storage tubes, and the material samples are pushed out through breakable ends of the cap by the prongs into a collection vial.

Abstract: A hydrodynamic bearing includes a fiber optic sensor for measuring static and dynamic bearing forces or loads during operation. The fiber optic sensor is positioned within the bearing through the most direct load path, which is through the pad support for a tilting pad style bearing. In additional to being positioned in the pad support of a tilting pad bearing, the sensor is also placed 1) inside the pad support or on the pad support structure, and 2) oriented perpendicularly with the shaft centerlines. After the sensor location is chosen and the sensor is properly positioned, a calibration procedure is utilized to determine the relationship between the radial load and measured strain for the specific bearing. Once the calibration factor has been determined, the sensor may be utilized in the bearing to measure load during operation.

Spring clips are detachably attached to the pins. A first end of a springy, forwardly bowed clamping bar is hinged to the first recurved end and positioned behind the support bar. To use, the support bar is positioned through the looped ribbons of a plurality of medals. The clamping bar is pressed against the back of the ribbons, and its free second end tucked under the second recurved end of the support bar to clamp the ribbons in position. In another embodiment, the clamping bar is separate from the support bar. In yet another embodiment, the mounting device is comprised of a T-shaped pin inserted through the ribbon of a medal.

Abstract: A sanding block includes a base member with a flat working surface for being positioned against a generally flattened sanding belt. A tightening arm has a first end hinged to a first end of the base member, and a second end movable between an open position away from a second end of the base member, and a closed position latched against the second end of the base member. A first retaining bar is secured to the tightening arm for engaging a first end of the sanding belt, and a second retaining bar is secured to the base member for engaging a second end of the sanding belt. When the tightening arm is opened, the first retaining bar is moved for slackening the sanding belt, and when the tightening arm is closed, the first retaining bar is moved for tightening the sanding belt against the working surface.

Abstract: A cubicle door is comprised of first and second brackets for wrapping over the top edges of a cubicle panel on opposite sides of the entry way. A roller blind has a proxiinal end hinged to the first bracket, and a distal end which is removably supported on a support attached to the second bracket.

The grooves allow the roller blind to meet the second support at different fixed angles to fit the shape of the entry way. Alternatively, a rotatable turret with a notch is arranged on the second bracket. The roller blind is received in the notch, and the second bracket may be oriented at different angles relative to the roller blind by rotating the turret.

All the segments are moved by the same amount relative to adjacent segments whenever the second end segment is moved by the linear drive to adjust the length of the spinal support for supporting spines of different lengths. A spinal manipulation device is movable within a longitudinal slot in the spinal support for evenly applying therapy to the length of the spine. The spinal manipulation device may be a reciprocating device, a roller device, or a water jet device.

Abstract: A massaging device includes a motor, and a rotatable head attached to the motor. A hinged handle is attached to the motor for providing an adjustable grip. Resilient beaters are arranged radially around the head. The beaters are respectively connected to keys by narrowed necks. The keys are detachably secured in longitudinal slots on the head, so that the beaters are detachable from the head. When the head is set spinning by the motor, the beaters are rotated for massaging the body to relax muscles or reduce cellulite. The beaters are easily removable from the slots for exchanging them with replacement beaters. Each beater is comprised of a resilient core, such as foam, completely enclosed by a flexible non-tacky cover, such as a neoprene or vinyl sheet. Although many resilient materials, such as foam, tend to be sticky enough to grab hair if exposed, the beaters do not grab hair because the resilient cores are completely enclosed by the non-tacky covers.
