Abstract: The invention is to an electrostatic fluid filter that includes a housing, a removable array of filter elements and alternately electrically charged plates positioned parallel to the fluid flow. The charged plates are mounted between spacers each of which includes a mesh made of an insulating material and further includes a plurality of parallel guide tracks positioned on the mesh for holding the charge plates, and where each guide track is adjacent to a conductive strip which is in electrical contact with the plate in that guide track so that the plates are in electrical contact with alternately either a positive or negative electrical terminal.

Abstract: The invention is to a puzzle toy which includes a solid body having a plurality of bore holes extending completely through the solid body such that each bore hole extends between two faces of the solid body. Some of the bore holes intersect with other bore holes such that pins inserted into the bore holes would interfere with at least one other pin in a bore hole. Some of the pins have at least one notch along its length to allow an interfering pin to partially pass through without interference. Each pin extends through a slide that moves the pin to one side after it is removed from its respective hole.

Abstract: An exercise apparatus has a first bar with two side bars, each side bar extending generally perpendicular from and attached adjacent to the opposite ends of the first bar. The first bar is rotatably mounted with respect to the side bars. A second bar is connected to said side bars of said first bar by one or more loops of cord. Adjustment devices are used in conjunction with the cord to adjust the distance between the first bar and the second bar. Accessory straps may be used in conjunction with the first bar to perform various exercises.

Abstract: A system for monitoring the steady state condition of a motor vehicle shock absorber is used to identify conditions in which a tire may be under- or over-inflated, or in which a shock absorber needs adjustment or replacing. A device for measuring distance, such as a measuring tape, is affixed along the length of a movable portion of a shock absorber, and is monitored by a shock absorber sensor, which is mounted in a fixed position relative to the measuring device. The vertical distance through which the movable portion of the shock absorber moves and the velocity of the oscillations of said movable portion is thereby monitored, and data is transmitted from the sensor to a circuit for transforming said data into a visual display for visual monitoring by the vehicle driver. Said data is further sent through a comparator circuit for comparing to other data received simultaneously from at least one other sensor similarly mounted in relation to another shock absorber of the vehicle.

Abstract: The invention is to a flexible connector for attaching license plates to a vehicle, where the license plate is subject to being hit or moved over objects that would damage the license plate. The connection incudes a spring and plunger in a main body. The plunger has a flexible arm formed thereon which has a key end that connects to a knob. The flexible arm extends through holes in the license plate and a mounting frame and holds the license plate secured to the frame by the knob attached to the key on the flexible arm. When the license plate is hit or moved, the plunger will compress the spring allowing the flexible arm to extend out of the body and flex sufficiently to allow the license plate to move with the force striking it.

Abstract: The invention relates to a small utility air storage tank that includes a pressure gage and an air flow regulator. The storage tank may be used alone or in conjunction with a second storage for storing and supplying a larger amount of air for use with an airbrush or air blower. The storage tank and second storage tank may be filled with air from an air source. One of the storage tanks may be filled by discharging gas cartridges into the storage tank. An auxiliary tank may be attached to the storage tank for use in sand blasting or to create a vacuum.

Abstract: The invention relates to a portable plating system that operates stand-alone with a battery power source, or with an A.C. power source. The system is also capable of working from an automobile battery as the power source. The system is packaged in a combination storage/work station unit which stores the plating equipment when not in use, and serves as a work station when the equipment is assembled and ready for use.

Abstract: The invention is to an aspirating tooth brush which has a vacuum drawn through the tooth brush handle and openings in the side of the tooth brush handle opposite the bristles, and an inlet in the end of the brush body to which the vacuum line is attached. The handle may also have a second channel in the handle for dispensing water into the mouth during brushing and aspirating.

Abstract: The invention is to a utility carrier for carrying balls, and for dispensing balls and holding balls during a ball game, and for storage of balls and bats, and other equipment between games. The carrier is attached to a fence or other object. Balls are held in the carrier, and a rigid handle attached to and suspended below the carrier has clips thereon for holding bats.

Abstract: The invention is to a mail box flag that is constructed to lock the flag in place, and to allow the flag to be raised by moving a lever that holds the free end of the flag. The flag is stored out of sight in a flat rectangular housing that has an outside surface that is constructed, in one example, to resemble a brick.

Abstract: The invention is to a ball toy and game method utilizing the ball device. The ball toy includes two hemispherical parts that may be separated to enclose an electronic timing device and a digitized voice module. The electronic timing device is actuated by pressing a button switch to initiate a randomly programmed timer. The randomly programmed timer will, at the end of the randomly programmed time interval actuated a voice module that will enunciate the word "gotcha", or any other programmed word.

Abstract: The invention is to a stool for use in a swimming pool. The stool has a single leg attached to a seat. A gripper device is placed on the end of the leg to prevent the leg from slipping when it engages the bottom of the pool.

Abstract: The invention is to a gamma matching antenna in which a motor driven shunt is used to adjust the gamma match feed line. The shunt is movable along the antenna driven element and the gamma march rod on brushes or rollers that are in good electrical contact with the gamma rod and driven element, and allows the shunt to move along both element without binding. A control circuit moves the shunt in response to, and to minimize the SWR of the antenna.

Abstract: The invention is to a jig that may be either temporarily or permanently mounted for use on a simple, low cost, belt or drum sander. On a belt sander, the jig is placed over the fence on the sander and secured thereto by thumb screws, or may be bolted to the sides of some sanders. The jig is mounted adjacent to a drum sander. The jig is an adjustable guide under which a work piece is placed. When the work piece is sanded to the desired thickness, the attachment is stopped from further downward movement by set screws, and the work piece is not further sanded.

Abstract: Disclosed is a pen holder device having two pen holders, one mounted vertically above the other. In each pen holder is a reduced enclosed end for receiving a pen tip, and a seal adjacent the enclosed end to prevent air circulation around the pen tip when the pen in the holder.

Abstract: Disclosed is an apparatus and method for aligning the flat edges of semiconductor wafers in a wafer cassette. The apparatus includes a roller and alignment blade mounted in a frame on which the wafer cassette is mounted. A motor mechanism rotates the roller and alignment blade to align the wafer flat edges.

Abstract: The invention is to a roofing material and the method of making the roofing material. The roofing material is in the form of a standard material know as "felt" or "tar-paper" that has a plurality of nail tabs attached to the felt base material prior to coating the felt base with a water resistant material such as petroleum "tar". In a second embodiment, the nail tabs are attached to the felt during installation of the felt on a roof. The roofing material is attached to a roof with roofing nails that are driven through the tabs.

Abstract: An apparatus and method for converting petroleum related hazardous waste material utilizes a modified tanker truck and a filter consisting of hydrophobic material and activated carbon to separate the water content of the waste while capturing the solids contend yielding a high BTU-content fuel.
