Abstract: An improved mechanic's creeper apparatus for use when working under a vehicle and the like includes a frame having an upper end, lower end, right side, and left side frame portions. A contoured deck or body platform is supported between the right and left sides. Each side bears at least three casters with wheels arranged in a non-collinear arc to prevent capture in a crack or expansion joint on the floor of the workplace. The upper end carries a height-adjustable headrest which remains parallel to the plane of the body platform when raised.

Abstract: A fish length measuring apparatus that incorporates a digital scale allows fishermen to both measure and weigh their catch without touching or handling the fish. The apparatus incorporates a housing with a lip grip to grasp the mouth of the fish. A viewable digital output screen is connected to a weight-sensing member whereby the weight of the fish generates a digital numeric display. A distance-measuring sensor projects a beam towards a surface adjacent the tail of the fish and detects the reflection from that surface, then calculates the distance (i.e., length) and displays the length on the output screen. The contour of the housing facilitates hand-holding of the apparatus, and a variety of unique digital data may be selectively displayed on the output screen.

Abstract: A removable Flash integrated memory module card has a plastic shell and an integral Flash memory module. On the backside of the card, there are exposed contact pads. When the card is inserted into a card-hosting device, the card can communicate with the device through the exposed pads. The manufacturing method includes manufacturing of the memory module and utilizing plastic molding techniques for making the card outer body. The method involves preparing the substrate, mounting the components, testing the module, preparing the molding device, and molding the card body.

Abstract: An electro-mechanical electrostatic air cleaner that combines a low air resistance dielectric fibrous filter material positioned between and electrically charged by two electrically resistant carbon coated screens. The screens are charged by a remotely mounted bi-polar power supply. A pair of post ionization electrodes charge particles in the air with opposite charges, causing the particles to agglomerate. A plurality of screens may be placed in an array for increased one-pass filtration.

Abstract: A utility table and storage apparatus for use in vehicles such as pickup trucks having a truck bed includes three main parts: a main frame, a rail system, and a tool storage system. The main frame is made up of a frame assembly with four collapsible legs. The legs have wheels, and are adjustable in height. The main frame forms the support structure for the work table, the top of which is preferably covered by a 4 ft. by 8 ft. piece of metal, plywood, or other suitable material. When the main frame/table portion is outside the truck bed, it rests on the four legs with the wheels attached, allowing it to be moved around. The rail system consists of three components, the anchor frame, the guide frame, and the transfer frame. The anchor frame is bolted down to the bed of the truck. The guide frame guides the transfer frame during movements of the main frame, and is temporarily bolted to the anchor frame, but can be removed if needed to allow the full use of the truck bed.

Abstract: An HVAC duct boot seal is disclosed which may be installed on vent openings during construction and prior to protect the ventilation system from contamination by construction debris entering the vent openings and to improve the vent seal after construction is complete. The boot seal includes a selectively removable cover portion, at least one side wall disposed at a substantially right angle to the cover portion and defining a recess for engagement with the edge of a duct boot opening, and a flange disposed outwardly from the exterior surface of the side wall. Also disclosed is a method of using the inventive duct boot seal.

Abstract: A wastewater treatment washer compactor system having in-channel motorized screen for installation in an influent channel and removal of screenings from the influent stream; at least one washer and at least one compactor for washing and dewatering the screenings; and system control means for coordinating and controlling the motor speed of the motorized screen, the washing cycle time and processing rate of the washer(s), and the compacting rate of the compactor(s).

Abstract: A combination trucker's belt and extrication harness is provided, said combination including a belt having loop portions and connection means at each of its ends, and a multi-use strap affixed to the second end and contained within a quick-open hook-and-loop fabric pouch. The multi-use strap includes a first ring connected to the loop portion of the second end of the belt, a short strap connected at one of its ends to the first ring and connected at its other end to a second ring, a long strap connected to the second ring and extending from the second ring through a snap connector having adjustment means and a tail portion extending beyond the snap connector which terminates in a third ring. The multi-use strap may be deployed for multiple uses, including aerial platform tethering, search tethering, and for configuring as a leg and pelvis reinforcement making the combination suitable as a low angle rescue harness and emergency rappelling harness.

Abstract: A fill door for use on the angled surfaces of furnace shells and chemical containers. The door is pivotally coupled to a door frame integral with the angled surface and includes a rim that mates with a female channel in the door. A U-shaped latch is pivotally connected to the frame and includes a threaded spindle operatively connected to crack. The surface of the door includes a female sleeve having a bore for accommodating the end of the spindle when the latch is over the door and the spindle is tightened into its closed and locked position. The door further includes a cantilevered arm having an angled bore which allows it to swivel around a substantially vertical cylindrical post connected to frame. The arm and door swing in a substantially horizontal plane around the axis of the post.
