Abstract: A depth assembly for use with a hand-held power tool (2) and including a motorized control unit for adjusting a position of a depth-setting member (3) and connectable with an energy source (4) which supplies power thereto, and a micro-controller (6) for controlling the operation of the control unit (5) and connected with a length-determining sensor.

Abstract: A cavity formed in a plate of a spine of a loose-leaf binder is open at the front of the cavity toward the back of the spine and is configured to hold a nut and prevent rotation of the nut in the cavity and to receive a threaded screw clearingly of the screw threads through the back of the cavity for threading the screw in the threads of the nut.

Abstract: An inline skate having an inline skate wheel; an in line skate axle which extends through the inline skate wheel and has a female receiving element; an inline skate frame which supports the inline skate axle, wherein the inline skate axle has a first contacting surface for contacting the inline skate frame; a securing element that has a second contacting surface for contacting the inline skater frame, and a male thread element for engaging the female receiving element of the inline skate axle, and a positive acting element for exerting a retention force against the inline skater frame, wherein the female receiving element does not have threads prior to engagement of the female receiving element with the male thread element, and wherein the male thread element is a self forming thread which forms a thread in the female receiving element upon engagement.

Abstract: A multipiece interfragmentary fixation assembly for interconnecting bone fragments across a fracture therebetween. The fixation assembly comprises a first axially elongated fastener having external threading for anchoring the first fastener into the bone substance of the first bone fragment. The first fastener defining a coaxial throughbore with internal threading extending along the length thereof. The fixation assembly also includes a second fastener attachable in non-movable relation relative to the second bone fragment. An elongated connector operably interconnects the fasteners such that rotation of the connector draws the fasteners and the bone fragments attached to each into a predetermined compressive relationship relative to each other. A retaining apparatus prevents the connector from inadvertently turning and thereby maintains the predetermined compressive relationship between the fasteners and the bone fragments to promote healing of the fracture.

Abstract: A robotic arm mechanism provides motion to an end effector via a motor driving a drive pulley. The drive pulley is connected by a belt structure to drive a driven pulley. The motor is mounted to a bracket. The bracket is slidably mounted to a base plate. The bracket is positioned relative to the base plate to provide desired tension in the belt structure. The bracket is fastened to the base plate by a bolt structure which extend from the base plate orthogonally to the motor. A threaded bore extends fully through the bracket from a distal mouth thereof removed from the driven pulley. The bore has an axis which is located generally in a plane which is contiguous with or parallel to the axes of the respective drive and driven pulleys. The bore extends from an opening facing the distal side downwardly to the base plate and towards the axis of the driven pulley. A set screw is engaged with the bore and extends through it such that the screw's tip forcibly engages with the base plate.

Abstract: A floatation device in the shape of a throwable airfoil, similar to the shape of a FRISBEE.RTM. brand toy, which can also be used as a cushion to sit upon. The device is comprised of a supporting structure which attaches to a bottom surface of a floatation structure. The supporting structure is preferably constructed of semi-rigid material which functions to maintain the proper shape of the device and is provided with a handle which is gripped by a person in order to throw the device. The floatation structure is preferably constructed of a soft, resilient material, such as polyvinyl chloride foam. The device is optionally provided with straps, arm holes, and central openings for holding onto the device when in the water and, optionally, provided with a bumper ring and a retractable handle mechanism for cushioning the impact of the device.

Abstract: A stacked array comprising at least one or more similar or dissimilar metals or composites and having either a tapered bore or a tapered sleeve. A tapered bolt adapted to be inserted into the tapered bore and having a taper that is different from the tapered bore. A method for selecting a greater or lesser taper on the bolt than the taper on the bore depending on the relative strength of the materials forming the stacked array as a means of reducing the installation force of the tapered bolt within the tapered bore.

Abstract: A removable blind rivet comprising a tube (1) with a head (3 or 6) on one end to contact one workpiece (11) of two workpieces (10 and 11) to be rivetted together, the other end (14) being upsetable against the other workpiece (10) by a pull pin (5) with a head (4) pulled into the tube, or by blasting an explosive charge (8) inserted in the other end (14) of the tube. The head is a removable nut (3) threaded upon the accessible end of the tube (1), or a spring washer (6) inserted in a slot (7) in the accessible end of the tube.
