Abstract: In one embodiment, the musical box includes a box-like support structure and a music device disposed in the interior of the structure. A plurality of flexible continuous webs are sized to wrap around the outside of the structure. Each web has, along its outside surface, indicia representative of a particular mathematical data table, such as a multiplication table. One column of the table indicates the mathematical resultant of the remaining laterally displayed data. The resultant is disposed proximate a side of the support structure. A controllably movable strip or continuous web has a window and the window is sized to reveal one mathematical resultant. This continuous windowed web is driven by a gear and knob actuator.

Abstract: The controlled explosion projectile ejection system utilizes a source of combustible gas through a controllable input valve into a combustion chamber. Inside the combustion chamber is a sparking means. After the chamber is loaded or filled with gas, a spark control signal is applied to the sparking means and the gas ignites. At the output of the chamber is disposed a controllable output valve. In a simple embodiment, the output valve is simply a valve head biased against the output port of the chamber thereby inhibiting any gas flow from the chamber unless the pressure in the chamber exceeds the biasing force against the valve head. After ignition, the gas expands and the resulting pressure is much greater than the biasing force on the output valve head and the valve opens. Downstream of the output valve is a barrel with the projectile loaded therein. The expanding gas passes through the output valve and ejects the projectile from the barrel.

Abstract: A flow control assembly designed to regulate flow of water from a showerhead through a foot operated and fluid actuated valve assembly. The valve assembly is disposed upstream of a flow of water issuing from the showerhead and a variable volume chamber is mounted on the floor or base of a conventional receptacle such as a bathtub. Foot pressure applied to the variable volume chamber controls the flow of actuating fluid into and out of driving contact with the valve assembly thereby positioning the latter between a valve open and a valve closed position.

Abstract: A cleaning assembly to be used underwater primarily for the cleaning by removing of debris from bottom and wall surfaces of swimming pools, spas, and like water containing structures. A movable carriage supports a pump assembly which includes an impeller driven by a water sealed motor which in turn is powered by a water sealed battery or like electrical power source self-contained on the carriage. The impeller communicates directly with an input and output portion of a water channeling conduit so as to force water and debris carried thereby through the conduit, beyond the pump and eventually to a filter structure located on the exterior of the carriage. The filter structure is porous and therefore allows return of water directly to the pool while retaining debris which is removed from the bottom or wall surfaces of the pool.

Abstract: A pulling adaptor assembly specifically structured to be readily assembled and disassembled and thereby presented in a kit-type construction adaptable to any of a plurality of conventional pulling mechanisms such as hydraulic ram wherein the subject assembly is intended to remove either a male or female anchor element from a concrete or like material base, slab, wall, etc. The components of the subject pulling adaptor assembly are cooperatively structured and disposed relative to one another to maintain and increase a distance between the pulling mechanism and the anchoring slab, wall or structure such that sufficient resistance can be presented to the pull shaft of the hydraulic ram or pulling mechanism in order to concentrate the exerted pulling force on the embedded anchor.

Abstract: A roller-ball assembly including a spherically shaped ball but comprising a multi-piece construction including a substantially centrally disposed roller element and two ball segments preferably disposed at opposite ends or sides of said roller element and fixedly secured to one another or to said roller ball structure generally such that the roller element is movable relative to said ball segments. A rolling surface is collectively defined by the external surfaces of the roller element and said ball segments wherein collectively the external surfaces define an external spherical configuration of the roller ball assembly. The external or rolling surface of the roller ball, due to its multi-piece construction, may be defined by one or more external surfaces of said roller element and/or ball segments concurrently engaging a supporting surface over which the roller ball travels.

Abstract: A multi component butt of the type designed for use in combination with a fishing rod used for trolling from the back of boats generally some distance from shore. The butt includes an elongated shank portion comprising a major length of the subject butt and having a hollow interior portion of substantially straight line, linear configuration wherein the hollow interior portion has a substantially common inner diameter extending along a vast majority of its length. A gimble is press fitted into one end of the shank portion and a guide tube is press fitted into the opposite end so as to protrude outwardly therefrom to accomplish a bonded fixed engagement with reel seat tube on which a reel used in combination with a finishing rod is mounted. One or more additional bushings may be disposed, through press fitting, on the interior of the shank portion for further retention and stability of the end of the rod passing into the interior of the shank portion through the guide tube.
