Abstract: A self centering guide pipe axis laser guide is based on the use of three parallel links spaced 120 degrees apart which are engaged to be expanded or contracted. When expanded the links contact the inside diameter of the pipe which accordingly establishes the center axis of the pipe. The driving means for the links is a rotating screw mounted in a base centrally located with respect to the three links. In the front of the base is a laser module whose beam is aligned with the center axis of the pipe once the links contact the inner diameter of the pipe. Gauges mounted in a saddle on top of the pipe determine the proper slope once the center axis has been established. A calibrated scale on the guide can be used for determining both inner and outer diameters of the pipe. While the laser guide has been illustrated in determining the center line of pipes, it also has other uses such as aligning pillow blocks to a center line.

Abstract: An intramobile element for dental implants that includes an elastic, flat, circular washer having rounded edges, being 0.75 mm in height and designed to fit neatly on existing abutments and a prosthesis that comprises a gold member to which a porcelain cover is cast. The gold member has a cylindrical head with an internal cradle to precisely support a gold retaining screw with a rounded head and a screw channel spaced from the screw threads to allow for rotation of the prosthesis and making use of existing specific length abutments to control placement of the washer either supragingivally for hygienic reasons or supragingivally for esthetic reasons.

Abstract: Specially designed healing caps with varied bottom surfaces and different shaped channels and diverse shaped lockwashers for obviating loosening of the healing cap when screwed into an implant fixture. The healing cap has a retaining screw separate from the cap body and the combination of healing cap and lockwasher also prevents breakage of the cap body or fixture or both due to excessive torque and prevents gingiva from growing over the fixture at any point.

Abstract: A repair flange comprising members of flat, thin, preferably non-corrosive sheet material dimensioned so as to be flush mounted over finished floor surface. The repair flange is designed to fit around the necks under the attachment rim of various size closet flanges and has an opening offset from the usual circular opening wherein the inner edges of two flange members can be proximate one another, spaced a distance apart or staggered. The flange members wherever their location, fit closely around the neck of the closet flange and the flange body extends over the floor surface beyond the area encompased by the rim of the closet fiancee so that attachment to the floor material can be made beyond the base cf the closet flange. The repair flange primarly adapted to repair floor material directly under the base of toilet bowls which contributes to a snug and tight connection of the toilet bowl to the floor system.

Abstract: A universal thermoplastic U clip adapted to be fastened to the apparel of a user and having a pressure sensitive adhesive affixed to one of its legs for supporting diverse semi-flat non-porous articles. The article is fastened to the adhesive by moderate pressure and is permanently secured.

Abstract: A pet entrance pager in the form of a channel like member designed to be fitted over the vertical edge of a door and held tightly against the sides by a non-skid material. The rear of the channel is fitted with an alarm assembly activated by a cover plate spring mounted on one of the channel sides and having a switch, which when activated by an animal pushing on the cover plate trips the alarm assembly. To attract the animal the pager is sprayed with scent. In the event the door is not of standard size inserts are placed channel and the door.

Abstract: A roundabout adapted for play or exercise in the yard using one or a plurality of bicycles secured by top and bottom mounting assemblies to a mounting post rotatable about a fixed post solidly implanted in the ground. The bike or bikes are fastened to mounting assemblies by straps and can be readily disassembled by simply unbuckling the straps. The ground post can be removed and the same placed in another area of the yard. Motive power is supplied by a small wheel placed exteriorly of the front bike wheel and fastened on the bottom mounting assembly.

Abstract: A data management method for representing hierarchical functional dependencies. Data are modeled as assertions assigning values to attributes along a path of dependencies. Attributes are created by specifying their parents and are assigned identifiers which distinguish them from their siblings. Assertions are stored as storage sequences, which are identifiers corresponding to the attributes of a path alternating with values assigned to the attributes. Storage sequences are stored as indices of a hierarchical data structure. Application values are stored in the tree with predecessors, and deleted with dependents. Assertions are denoted by function assignments which assign values to function instances. Function instances may reference multiple values, and attributes may be created at any time. Data storage, access and deletion are efficient.

Abstract: A repair flange comprising members of flat thin, preferably non-corrosive sheet material dimensioned so as to be flush mounted over a finished floor surface. The distinguishing features herein are that this repair flange is designed to fit around the necks under the attachment rim of various size closet flanges and has an opening offset from the usual circular opening wherein the inner edges of two flange members can be proximate one another, spaced a distance apart or standard. The flange members wherever their location fit closely around the neck of the closet flange and the repair flange body extends over the floor surface beyond the area encompassed by the rim of the closet flange so that attachment to the floor material can be made beyond the base of the closet flange. The addition of guide marks on the flange members facilitate the positioning of the flange members with respect to the closet flange.

Abstract: A bolt head assembly comprises a circular bottom and a longitudinal straight walled section extending upwardly therefrom. Only the longitudinal section is threaded. A separate shank is threaded into an internal threaded portion of the bolt head. A washer and nut at the end of the bolt are used to secure a commode. In the event that the commode has to be replaced or any other exigency exists the shank can be easily removed from the head despite binding of the nut and washer to the bolt because of corrosion. Application of torque to the nut would cause the threaded shank to separate from the internal threaded portion of the head and be removed along with the nut and washer.

Abstract: A paint brush configured to facilitate cleaning, prevent stiffening of the bristles and extend the life of the brush having a dome shaped member positioned between the lower end of the bristles and ferrule.

Abstract: A brightly colored semi-trapezoidal car trunk carrier tray made of plastic having a plurality of compartments some of which are adjustable in size by use of inclined insertable slats, some compartments having restraining modules for stabilizing the position of large or odd sized articles, spaced hangers on at least one side of the tray, a fastener and a recessed magnet on the bottom of the tray and sectionalizing the tray to make it smaller or larger.

Abstract: A leveling device for stabilizing furniture positioned adjacent a wall and resting on carpeting comprising an insert in the form of a plate with a nose forming an angle having a jack embedded in the vertical nose of the angle. The jack comprises U-shaped legs that puncture carpeting and padding and rest on the floor.

Abstract: A method for packaging electric wiring by using a grasping tool to assist in ensleeving the wiring in a plastic sleeve. Subsequent to ensleeving the grasping tool is disengaged. The sleeve with the enclosed wiring is folded over to form a neat compact package which is secured and ready for storage.

Abstract: A light weight portable transistorized radio receiver having male outlets in the rear and female outlets in the front. The male outlets plug directly into a standard A.C. electrical energy source and the female outlets are adapted to receive connections from an assortment of electrical appliances.
