Abstract: A holder for a concrete slurry hose connectable to support a hose for dispensing a slurry at an elevated location such as at the top of a wall. The holder comprises an elongated body which is to be supported at the top of the wall. The body includes a pair of straps which would be secured to the hose some spaced distance from the dispensing end of the hose. The lower end of the body includes a pair of handles. These handles are to be grasped and used by a human to facilitate movement of the body to various locations along the wall.

Abstract: A bolt on drive assembly for a core drill which utilizes a spoked reinforcer mounted between a pair of discs. The discs are removably mounted on the tube by bolt fasteners. A drive connection is removably mounted and centrally located on a outer disc of the pair of discs. The drive connection is adapted to connect with a drive shaft to cause rotation of the tube.

Abstract: A first embodiment of electrical connector assembly establishing direct power to a plug-in module which utilizes a female connector that is electrically connected to a pair of spaced apart buss bars. The female connector is mounted in a fixed position in conjunction with a backplane. A male connector, which has a pair of male pins, is electrically connected to the female connector with this male connector to then be electrically connected to a plug-in module. A second embodiment of electrical connector assembly is for establishing a direct power supply to a mezzanine printed circuit board which is mounted parallel to but spaced from the plug-in module. The second embodiment of electrical connector assembly also utilizes a female connector that is connected to a pair of spaced apart buss bars. A male connector is then mounted in conjunction with the female connector with this male connector being mounted on the plug-in module.

Abstract: A tool instrument which has a plurality of elongated tools mounted within a housing. Each tool is separately movable relative to the housing between a retracted position located within the housing and an extended position projecting outwardly from the housing. The normal at-rest position for each of the tools is in a locked position relative to the housing. Manually pushing onto a button will cause a shaft to be moved to disengage the tools and permit the tools to be moved relative to the housing.

Abstract: A pliers which has a pair of heads with these heads being reversible so that one head is in a usage position the other head is in a stowage position located between a pair of handles. Each handle of the pair of handles is pivotable about one hundred sixty degrees with the handles to be located in juxtaposition in both the usage position and the stowage position. Each handle including a convex surface and a concave surface and also each handle including a pommel. Each of the convex surfaces and each of the concave surfaces and each of the pommels function to ergonomically assist in grasping of the handles.

Abstract: A pet litter collection bag and spatula which comprises a flexible walled bag which has a closed end and an open end. At the closed end is mounted a spatula with a graspable handle of the spatula extending within the confines of the internal compartment of the bag. The spatula is thin and bendable so as to be manually deformable to accommodate to the shape of the terrain on which it is being used to scoop up the pet litter. Once the pet litter is located on the spatula, the bag is reversed in position enclosing the front portion of the spatula with the open end of the bag to be tied to a closing position.

Abstract: A pipe coupler for joining a pair of pipe sections in a fluid tight manner. A hollow connector has an internal chamber within which is to be located a pipe section. Surrounding the pipe section and mounted in conjunction with the connector is a coupler. The coupler includes a grab ring housing. Formed within the grab ring housing is an annular concavity. Mounted within this concavity is a grab ring which includes a plurality of pivotable biting members which are arranged to dig in the wall surface of the pipe section when the pipe section is longitudinally moved a limited withdrawing distance from the connector.

Abstract: A diffusion cell to facilitate the automatic or manual removal of test aliquots of liquid from a receptor chamber of the diffusion cell so as to determine percantaneous absorption through a membrane of a substance from a donor chamber into a receptor chamber of the diffusion cell. There is utilized a capillary port through which the test aliquot is to be removed. A refilling tube connects also with the receptor chamber to add receptor liquid into the receptor chamber as the test aliquot is being removed. A quick release clamping apparatus secures the donor housing which contains the donor chamber tightly to the main housing of the diffusion cell.

Abstract: An artificial fishing lure which has a pair of interconnected tumblers. The tumblers are to rotate when the fishing lure is moved through water which is to be an attractant to a fish to induce striking of the lure. By the interconnecting of the tumblers, the tumblers are always rotated at the same speed but in opposite directions thereby balancing the movement of the tumblers on the lure assuring that the lure always moves in an upright position through the water and does not turn over which would twist the fishing line to which the lure is attached.

Abstract: A floating heat exchanger for pond liquid and a method of evaporating water from the pond liquid that utilizes a mass of pipes that are floated at or just below the surface of the pond liquid with one end of the pipes being connected to an inlet manifold and the opposite end of the pipes connected to an outlet manifold. The pipes and manifolds are part of a heated closed loop heat transfer fluid system. The pond liquid is raised in temperature which facilitates the evaporation of water and the concentration of dissolved or suspended solids within the pond liquid.

Abstract: A handheld air injector apparatus that is to be used in conjunction with an airtight closeable container where the injector apparatus is to connect with a container and supply air within the container to a preselected level.

Abstract: A cutting disc core for a circular shaped saw blade which has a circular shaped body which has a center hole and a circular peripheral edge upon which is to be mounted a plurality of spaced apart cutting segments that is to perform the cutting of the saw blade. Surrounding the center hole and formed within the body are a plurality of slits with there being a solid tab that is integrally connected to the body located between each directly adjacent pair of slits. The tab constitutes a frangible seal with the circular ring or bushing which is formed about the center hole to be removable by being forcibly physically separated from the body.
