Abstract: A first embodiment of a toilet seat lowering device is provided for coupling to the toilet handle of a toilet system to lower a vertically positioned toilet seat. The device consists of a tubular member which is positioned over the handle of the toilet system and a spaced wedge member for sliding between the toilet lid and seat. The sleeve and wedge member are connected together by a wire member. Upon operation of the toilet handle, the wedge slides between the toilet lid and toilet seat to lower the latter to the toilet commode. In a second embodiment of the invention, the toilet lowering device consists of a pair of holding members for holding the toilet lid and a wedge for causing a vertically positioned toilet seat to be lowered when the toilet handle is operated. A plastic connector connects the toilet handle to the toilet lowering device.

Abstract: The invention concerns an apparatus and technique for detecting the voltage of A.C. high voltage lines. A radar wave is transmitted towards the high voltage lines and is reflected to a detector when the AC voltage drops to threshold level. Reflection continues until the AC voltage cycles to the threshold level on it second half of the cycle. A time interval is calculated for radar reflection and non-reflection, and a ratio thereof is calculated by a microprocessor which generates a display indicating the voltage carried by the AC lines in accordance with the time interval ratio.

Abstract: An improved assembly of rectangular frame carrying a strand of inward-pointing Christmas tree lights includes a shoulder in the inner end of each hole for a light, limiting inward travel of the light on simple assembly in which the lights and sockets are pushed through from the outside; for instant assembly/disassembly an elastomeric band around the outer perimeter in a groove in the frame retains all lights and can help retain the assembly in a window frame, if desired, together with one or more plunger type retainers.

Abstract: A tubular expandable elastic container for holding and dispensing a frozen confection as it thaws. The frozen confection holds the container in an expanded configuration, and as it thaws the contraction of the container forces thawed frozen confection from an open end of the container. A whistle is also provided at the open end of the container and a valve in the whistle structure for preventing air from entering the container when a user blows air into the whistle.

Abstract: A hinge mask product is provided, which consists of two substantially rectangular parts, with one of the parts having a tab for removal of this one part. One part of the mask is for the face of a hinge positioned and coupled between door and a door frame. The other part of the hinge mask is for the pin of the hinge. These parts of the hinge mask are used to mask the front face of the hinge and the hinge pin to prevent them from being covered by paint, stain, lacquer, or similar material when the door and door frame are located with a material, such as paint, lacquer, and the like. Hinges are of several standard sizes, and there are several specialty sizes. The hinge mask can be manufactured to cover both standard and specialty sizes.

Abstract: An infant-protecting sunshade for use in a land vehicle such as an automobile with an infant car set or a stroller. The sunshade is a unitary member stamped in the shape of a flat mushroom from flat sheet rubber and bent at fold lines to form a hood having a back insertable for support behind an infant car seat, a forwardly foldable top, and first and second downward sides, foldable up and securable by hook and loop fastening over the top when not in use. Being flexible, either or both sides can, in tight quarters, be rolled up to pass an obstruction such as the inside wall of an automobile.

Abstract: An elongate brush with handle forming a "T"-shape, has a plurality of cups along a top portion, all facing generally toward an end of the elongate brush so that with the elongate brush vertical it can be used for stirring asphalt-type compounds in buckets and for dipping out predeterminable quantities and spreading them, with or without use of a rubber spreader fixed parallel with the elongate brush. The plurality of cups can be made as a unit and need only cover about half the length of the elongate brush from the handle to the end opposite the end that they face. Inclined brush shape is disclosed to facilitate pouring.

Abstract: An improved nasal prosthesis is disclosed. The improved nasal prosthesis is adjustable and therefore provides a single design which is adaptable to a variety of patients. The improved prosthesis includes an adjustable strut and adjustable rings.

Abstract: A ladder beacon is provided which will aid firefighting and rescue personnel in locating a ladder in adverse conditions such as darkness, smoke and fog. The ladder beacon is a small self contained strobe light which is affixed to the top rung of a ladder and which is automatically activated when the ladder is raised to a vertical position.

Abstract: A knockdown mobile forms cart is provided which requires no tools to assemble or disassemble. The cart is assembled from welded and chrome plated steel wire components including a base, side pieces and a tray having folding end pieces. Stacking trays allow two or more trays to be supported by a single base. The components interlock, resulting in a rigid structure. Casters are also provided.

Abstract: A hydraulically operated elevator door mechanism includes a motor-driven shaft connected to rotate gears within a fluid reservoir. Fluid is "pumped" as the gears rotate, to one side of a piston, propelling the piston. The piston is connected to two pulleys over which a cable length is attached to the elevator door. Piston movement causes the pulleys to effectively shorten the length of cable between the pulley and door, which in turn, causes the door to slide.

Abstract: The invention is an improved dental instrument for scaling by ultrasonic operation. The scaler is coated with diamond particles to overcome the patient discomfort associated with the prior art chipping and dislodgement procedures. Four unique and novel scaler configurations are provided for various aspects of dental work, each is diamond coated and fitted for ultrasonic operation at lower power settings than present prior art instruments.

Abstract: A postal decal (stamp) which may be purchased regularly as a stamp is developed such that it carries a separable part of which is available for entering a destination identifier code (e.g. zip code) with the proper tool which can be a pen or pencil. These identifiers are written such that they are machine readable. Thus the process of sorting the mail and parcels to their destination can be greatly enhanced together with less human intervention for sorting. These stamps may be obtained at the usual post offices. If special pens or pencils are needed, they can be provided also at those post offices or at any other outlet. A second type of stamp is developed where the part designated for entering the destination identifier is thinly coated partially or totally with a magnetic or illuminating or coloring material which can be detected by the appropriate `reading` or scanning machine which reacts sensitively to this coating material.

Abstract: The invention is an improved anchor for machine bolts and other similar fastening devices in masonry or other materials. The improved anchor consists primarily of a two-piece body structure. When in use the two-piece body structure is arranged for receiving a fastening device, such as a machine bolt or other similar fastener. The two-piece body structure is cylindrical on the exterior thereof with the offset between the first and second of the two pieces of the body structure being a cut or separation through the body structure at an angle to the longitudinal centerline of the two-piece body structure. Each of the two pieces of the two-piece body structure has a plurality of saw tooth-like cuts or serrations on a portion of the exterior surface. The saw tooth-like cuts on the first piece of the two-piece body structure being located 180.degree. from the saw tooth-like cuts on the second piece.

Abstract: The invention concerns an emergency lighting apparatus which is activated by a homeowner in the event of an emergency. Transparent house numbers are illuminated from behind, while a strobe light is flashed. The illuminated numbers are mounted on the face of a first compartment and the strobe light is mounted within a second compartment. The two compartments are surrounded by a water-tight housing which might be readily attached to a building.
