Abstract: An exercise unit or weight machine which may be mounted to a door frame for use. The device is designed for portability in that the unit may be quickly mounted to the door frame and dismounted therefrom, and is symmetric so as to allow the device to be used on either side of the door frame.

Abstract: A filter for filtering gases, such as air, using a backing material on the downstream side of a filter media to prevent the filter media from blowing out, or separating from a frame. The backing material is congruent in shape with the filter media, so that if the filter media is pleated, the backing material is pleated in a like shape. The backing material may extend to an upstream side of said filter media so as to further aid in blow out resistance.

Abstract: A fuel overflow collection device having a bag which is placed under a fuel outlet or overflow on a vehicle, such as a boat, to collect fuel spillage or overflow during the refueling process. A first embodiment is attached to a side of a vehicle, such as by adhesive means, underneath a fuel overflow so as to collect fuel therein. A second embodiment attaches to a fuel outlet or overflow so as to collect fuel overflow or spillage during the refueling process.

Abstract: A damping control device which can be used to control the rate of movement or prevent the movement of a handle or other control means, such as a handle which is used to operate valves. This invention relates to control devices such as handles generally, and is more specifically directed to a damping means which can be used in conjunction with control devices, particularly those used to operate valves, to control the rate of actuation of said control device.

Abstract: Perfluoroalkanes, including perfluorobutane, perfluoro propane and perfluoropentane are used in aerosol spray compositions contained within aerosol spray containers to act as propellants. Further, perfluoroalkanes are combined with sulphur hexafluoride for use as aerosol propellants. Specific examples, including insecticide formulations, are particularly set forth.

Abstract: A paint brush holder which allows a paint brush to be incremental lowered into a paint can as paint is removed from the brush from the can by means of the brush. The holder as characterized by a plate which rests in a pivotal fashion on the edge of the paint can, with one end of said plate lowered into the paint can by means of a tie attached to the paint can opposite said plate.

Abstract: A restraining device having an anchorage the length of which may by contacted so as to cause pads on the ends thereof to apply pressure to the sides of an elevated work surface to secure the anchorage, and further having a tether, one end of which is attached to the anchorage, and the opposite end of which is attached to a harness which is worn by a worker so as to keep the worker from falling from the elevated work surface.

Abstract: A geothermal heating and air conditioning system having heat exchange coils located vertically in the ground is provided with a condenser receiver and a metering system which allows a relatively large amount of refrigerant to be used within the system for maximum efficiency without the problems of liquid refrigerant buildup which have been previously associated with geothermal systems using vertical coils.

Abstract: This invention is an insulation device and material comprising fiberglass covered or sandwiched between polyethylene or woven polyethylene. The invention as disclosed herein has superior insulative characteristics over and above the use of fiberglass alone or fiberglass covered by paper, foil or plastic materials commonly found in the prior art. The invention is particularly well suited to the insulation of liquid containing vessels and conveyance means, such as water heaters and pipes.

Abstract: A package is disclosed herein which may contain a fluid material which is capable of being discharged from the package by the application of manual pressure from a thumb and a forefinger to the package so as to cause the package to burst in a controlled fashion to discharge the fluid material contained within the package. The package may comprise a second chamber which receives the fluid material discharged from the first chamber after the first chamber is burst by manual pressure so as to further control the rate and manner of discharge of the fluid material from the package.

Abstract: Disclosed herein is a magazine for repeating shotguns, which may be incorporated into existing repeating shotguns, comprising a box type magazine which intersects the magazine of the shotgun so as to receive shells into the magazine tube from the magazine, and a shell drive assembly which traverses the magazine tube so as to position a shell which has entered the magazine tube into a firing chamber. This invention incorporates the manual action slide of a manual, or pump, shotgun to actuate the shell drive assembly, and uses the gas pressure actuation means of an automatic shotgun to provide movement of the shell drive assembly.

Abstract: This invention is a container in which bait may be contained, and which may be inverted so as to allow bait and water to enter a portion of the container which is then separated by a porous means from the remainder of the container, so that when the container is returned to its upright position belt is separated into a portion of the container for easy removal from the container.

Abstract: A torch positioning apparatus controls a torch as it moves downward at a relatively rapid rate toward a work piece until it trips a proximity switch, causing the rate of travel of the torch to be slowed. The torch continues its travel until it strikes the work piece and stops, and the increase in the level of power required upon stopping is detected by a circuit which compares this increased power requirement with a power level previously measured and stored while the torch is moving, causing the direction of travel of the torch carriage to be reversed for a preset time so as to position the torch at the desired height above the work piece. A safety mechanism is included which shows the travel of the carriage in case the proximity switch fails.

Abstract: An improved rigid filter plate for use in sludge dewatering or oil and water separation is characterized by a lower layer of relatively large material and an upper layer of relatively smaller material bonded thereto, with grains of sand interspersed within the upper layer and bonded to the material making up the upper layer. The device yields high efficacy in sludge dewatering and oil and water separation, while requiring a low level of cleaning and maintenance, yet is resistant to damage from mechanical cleaning when cleaning is necessary. An efficient and economical method of producing the device is also disclosed herein.

Abstract: Disclosed herein is an electrode which may be used in plasma cutting torches which has a superior service life over similar electrodes found in the prior art, due to a design which improves cooling of the electrode, and which allows advancement and resurfacing of the electrode insert.

Abstract: A device is disclosed herein which will apply strips of plastic to paper, such as kraft paper, transversely to the travel of such paper as it is fed from a roll. The resulting paper may then be formed into a bag by machinery commonly in use in the industry, without modification, with the resultant bag having a leakproof, waterproof bottom.

Abstract: A device is disclosed herein which may be used to simultaneously squeeze and shape a quantity of hams or other meats during the cooking process. The device comprises pairs of racks or trays with one of each pair being fixed and one movable. The pairs of racks are spring loaded to pull the movable rack toward the fixed rack to squeeze and shape the meat located between them during the cooking process. A hydraulic cylinder or other power means is attached and actuated to simultaneously separate the trays before and after the cooking process to load and unload hams.
