Abstract: A puller tool for removing bearings and like items from a blind hole comprises a plurality of fingers mounted within channels on a circular guide member for radially directed motion. The fingers include an outer wedge portion for insertion between an annular face of the item and a seat surface of the hole, and a radially inner cam surface arranged for engagement by an elongated actuating member to which the guide member is threadably mounted for forcing the fingers in a radially outward direction.

Abstract: An apparatus for the controlled feeding of concrete strengthening and adhesion material, such as plastic fibers, to a concrete mix. The apparatus includes a set of reciprocating spikes that contract the fibers with a comb-like action that separates the individual fibers and moves them forward to a rotating agitator having a central rotating shaft with spokes extending outwardly to provide a further separation of fibers and a forward movement of the fibers toward a rotating impeller which moves the fibers forward and downward to a duct which exits to a concrete mixing apparatus. The separation of the fibers prior to entry into the concrete mix serves to inhibit or prevent subsequent aggregation or balling of the fibers in the mix.

Abstract: A method and apparatus for engrafting a blood vessel is disclosed. The apparatus includes a hollow tubular graft of a preselected cross section having a proximal and distal end containing compressable and expandable nitinol springs, and connecting bars to facilitate physical communication between both springs. Furthermore, the apparatus contains a transport and deployment member for delivering said hollow tublar graft to an engrafting site within a blood vessel. The transport and deployment apparatus is comprised of an insertion catheter having a graft balloon and a tip balloon, as well as multiple inner tracks for injection of fluid into said balloons and the blood vessel interior. The method includes transport and deployment of said graft, as well as non surgical movement and removal of said graft in the event of misplacement.

Abstract: A marker light device includes a bendable printed circuit board, a group of light emitting diodes disposed on the bendable printed circuit board and electrically connected thereto, and a power source electrically connected to the bendable printed circuit board, thereby causing the illumination of the group of light emitting diodes. The bendable printed circuit board includes an electronic circuit for intermittently turning the group of light emitting diodes on and off at a predetermined time interval to provide a flashing light. The bendable printed circuit board, when folded such that the opposite ends thereof substantially meet, includes two panels such that the group of light emitting diodes disposed on the first panel faces in a direction generally opposite to the group of light emitting diodes disposed on the second panel, whereby the light emitting diodes project light in substantially parallel beams.

Abstract: A toilet flushing apparatus. The toilet flushing apparatus includes a vacuum fan for generating a partial vacuum for transporting solid and liquid waste from a toilet bowl to a sewer drain, a sensor for detecting a level of flushing water in the toilet bowl, a selector for selecting a defecation flushing node and a urination flushing mode, and a control, including a solenoid, for controlling time operation of time vacuum fan. The solenoid is responsive to a signal from the selector for supplying a relatively large amount of flushing water in the defecation flushing mode, as well as responsive to a signal from the sensor for supplying a relatively small amount of flushing water in the urination flushing mode.

Abstract: Inventory monitoring apparatus capable of real-time counting of objects added to or subtracted from a location whose inventory is to be monitored. The apparatus includes structure for supporting a plurality of objects and at least one lever adapted to be contacted and displaced by movement of the objects to and from the supporting structure. Movement of the lever in one direction triggers a switch which generates a signal indicating that an object is being added to the support structure. Similarly, opposite movement of the lever triggers another switch which generates a signal indicating that an object is being removed from the support structure. A microprocessor receives and counts the signals generated by the switches to provide a real-time total of the quantity and, if desired, the locations of objects borne by the supporting structure.
