Abstract: A swimming pool filter apparatus cover providing protection to a pool service technician servicing the filter apparatus, the cover forming a barrier between the technician and the filter apparatus. The filter apparatus is of the type having a central cylindrical body with upper and lower hemispherical portions, and an outwardly protruding flange base, with water inlet and outlet pipes intersecting the cylindrical body. A removable top cap which, when removed, reveals an entrance opening through the upper hemisphere. The technician extends his arm through this opening to remove contaminated sand or other filter material for replacement. The cover consists of a heavy flexible vinyl material having a rectangularly shaped main body to encircle the filter apparatus cylindrical body.

Abstract: A windshield for providing protection against wind and water spray for a driver and passengers in open boats of the type having a spaced apart driver's console and passenger's console, the windshield having a first and second panel operably attached to the boat floor situated between the two consoles, rising vertically upward to deflect wind and water spray. The two panels are held together at an angle by a centrally located hinge and secured to the floor of the boat by flexible holding members, the panels further secured by attachment to the consoles through additional flexible holding members attached to the upright sides of the panels. An alternate embodiment provides additional curved windshields attached to the first and second panels which are also attached to and residing above the driver and passenger's consoles respectfully.

Abstract: A device to restore the water level in a toilet bowl is disclosed wherein bleed water issued by the float actuated valve in a toilet tank reservoir is used to prime a syphon tube so that additional water from the toilet tank reservoir is shuttled down the overflow pipe to the toilet bowl to restore the toilet bowl water level during shortened partial flush operations of the toilet. The syphon tube consists of an inverted "U" shaped tube having one leg situated interiorly the overflow pipe and the other leg reaching down into the water of the toilet tank. The syphon tube operation is commenced by the bleed water injected into the base of the syphon tube through an initiator tube intersecting the syphon tube base so as to direct bleed water into the leg residing in the overflow pipe. An air vent opening situated in the initiator tube is effectively covered by water running through the initiator tube so no air is permitted to enter the syphon tube to disrupt the syphon operation.

Abstract: An improvement for a dual flush mechanism which permits a partial flush of a toilet in addition to the full flush. When the operator pushes the partial flush handle down, the partial flush mechanism lifts the flapper valve off the annular valve seat a small distance by raising the connected flush lever arm a similarly small distance. The improvement is a flush lever arm holder adapted to suspend the flush lever arm in the slightly raised partial flush position after the operator has released the partial flush handle. More particularly, a rotatable cam resides on a plate secured to the toilet tank wall, the cam, operably attached to a float, engages the underside of the flush lever arm such that the float holds the rotatable cam under the flush lever arm to secure it in the raised position during the partial flush. As the water level in the toilet tank falls, the float begins to fall with the water and lowers the cam holding up the flush lever arm.

Abstract: A linearly adjustable fluid damper of the sliding plate adjustable orifice type damper system having a fixed plate with a plurality of specifically arranged hexagonal shaped apertures therethrough and a slidable adjustable plate also having a plurality of specifically arranged hexagonal shaped apertures therethrough. The sliding plate is juxtaposed the fixed plate such that the apertures of the sliding plate overlap apertures of the fixed plate with center lines bisecting the top and bottom sides of apertures in both plates coinciding. The area of the resultant hexagonal composite orifice through both plates varies non-linearly from full closed position to full open position throughout movement of the sliding plate, however, the result is that fluid flow from zero to maximum through the resultant orifice is a straight line relationship with linear displacement of the sliding plate.

Abstract: A camera stabilizing support for steadying (either still or moving at a constant rate) a camera and/or camera and accessories by a photographer while taking pictures. The device includes a shoulder stock having an upper arm and lower arm which together substantially encompass the photographer's shoulder, an extension member attached to the shoulder portion, and a rectangularly shaped enclosure frame attached to the extension member. The rectangularly shaped enclosure frame is so constructed as to provide a hand piece for the photographer to grip and hold the invention during picture taking as well as carrying over long distances. In addition, as part of the enclosure frame, an upper camera and accessories plate and lower strobe light and tripod plate are provided. The upper plate is adapted to receive a release mechanism for securing the camera and lens and the lower plate alternately or simultaneously secures a strobe light bracket and a tripod.

Abstract: A collection pan for leaked waters from evaporative coolers is disclosed wherein a rectangularly shaped tray or pan resides underneath an evaporative cooler. The pan is characterized by four up extending sides at the outer perimeter of a flat rectangular base, the sides in height preferably greater than the sides of the base of the evaporative cooler.Generally central to the collection pan situated at a position to conform to the location of the outlet duct in the base of the evaporative cooler is an opening duct, the opening duct also characterized by four up extending sides. This opening duct is adapted to protrude into the outlet duct of the evaporative cooler with the sides of the opening duct in close proximity to the sides of the outlet duct. The height of the the outlet duct sides of the collection pan are greater than the sides of the evaporative cooler outlet duct and, also greater than the height of the sides of the collection pan.

Abstract: A supercharger for automotive engines utilizing the automobile flywheel as a part of the air compressor means is disclosed wherein air compression type vanes are attached to the flywheel. A donut shaped plenum encompasses the flywheel with the attached vanes, the donut shaped plenum open at its inner peripheral opening to receive air proximate the driveshaft to which the flywheel is attached. The vanes on the flywheel compress the air as the flywheel rotates and deliver the compressed air via an output conduit to the automobile carburetor or to the intake manifold of the engine where it is mixed with gasoline for insertion in the cylinders.

Abstract: A noise cancelling microphone for use in noisy environments is disclosed wherein noise entering the front portion of the microphone housing to impinge upon the microphone cartridge diaphragm is also permitted to enter proximate the rear portion of the microphone housing through strategically located inlet openings. This allows noise to impinge upon the back surface of the microphone cartridge diaphragm to effect a cancellation of diaphragm vibrations. These strategically located inlet openings at the top and the bottom of the rear of the microphone housing are situated so as to be directionally orientated towards the greatest source of the noise, namely orthagonal to the directional line of the front inlet openings and out of the path of the incoming air.
