Abstract: An apparatus that separates a golf club head and a golf club shaft to which it is adhesively secured. A hosel push member is positioned in abutting relation to the hosel of the club head. An externally threaded guide tube is slideably inserted over the hand grip of a golf club shaft and is positioned in trailing relation to the hosel push member. A drive member in the form of a coil spring or a rigid tube is ensleeved around the guide tube, and a drive member push member screw threadedly engages the threads on the guide tube so that advancement of the drive member push member applies pressure upon the drive member. Heating the hosel after application of pressure onto the drive member weakens the adhesive and results in separation of the club head from the shaft.

Abstract: A compact disk changer includes a magazine having an inner body and an outer body that are rotatable independently of one another about a common axis of rotation. The inner and outer bodies are slideably interconnected by a helical member so that relative rotation between the bodies in a first direction increases the axial spacing between them and relative rotation in a second direction decreases the axial spacing. This construction reduces the size of the changer and does not require precision tolerances between moving parts. A plurality of compact discs are stacked within the magazine, and each disk is supported by a disk holder. When the disk at the top or end of the sack is to be played, relative rotation between the inner and outer bodies creates an axially extending space adjacent the selected disk and a playing mechanism is inserted into that space.

Abstract: A digital frequency synthesizer employs a predetermined residue number system to generate phase angle information. The phase angle information is then converted from the predetermined residue number system into a weighted binary number. A part of the weighted binary phase angle information is used to address a read only memory that includes predetermined initial data points at each address. A predetermined iteration process that makes use of some or all of the weighted binary phase angle information that was not used to address the read only memory is then employed in an iterative process to generate final data points for the predetermined waveform. The initial data points are stored in the read only memory as weighted binary numbers and the iterative process employs weighted binary arithmetic. A second embodiment stores the initial data points in the read only memory as digits from a predetermined residue number system and the iterative process employs residue number system arithmetic.

Abstract: An improved flow-through washing and scrubbing brush handle for interconnection at one end to a source of pressurized water such as a garden hose and connectable at the other end to flow-through type scrub brush or the like. The device may include structure for varying water flow therethrough for delivery into the scrub brush and further includes a telescoping structure which releasably secures a selected overall length between its sliding inner and outer tubes. Unique sealing arrangements also prevent water leakage anywhere along the device, including from between inner and outer tubes.
