  • Patent number: 6394807
    Abstract: A method of growing jaw bone and the related guided-tissue regeneration plate support and fixation system employed in the method where an isolated and protected space free from tissue impingement, occlusal loading, chewing forces or muscular pressure is created between the periosteum and the jaw bone. This space is created by first placing either a dental implant or a guided-tissue regeneration plate support and fixation system tenting-type support screw into the jaw bone. The plate portion of the guided-tissue regeneration plate support and fixation system, preferably made out of titanium, is a two-piece structure including a first support plate component having a peripheral region and a generally open central portion and a fine mesh screen juxtaposed over the central portion of the support plate and fixed to the peripheral region thereof.

  • Patent number: 6345964
    Abstract: A molten metal pumping device is disclosed that comprises a pump base including at least one input port, a pump chamber, and a discharge leading to an output port. A rotor is retained within the chamber and is connected to a rotor shaft. The device further includes a superstructure attached to and positioned above the pump housing, a motor on the superstructure, a drive shaft connected to the motor and a coupling connecting the drive shaft to the rotor shaft. The rotor extends beyond the input port to deflect solid particles thereby reducing jams and preferably is a dual-flow rotor, directing molten metal both into the chamber and out through the discharge. The coupling is flexible and has two coupling members with a flexible disc disposed therebetween. Another aspect of the invention is a housing for a transfer pump that includes a discharge leading to an output port and a button adaptor extending from the discharge.

  • Patent number: 6244537
    Abstract: An apparatus that permits a rotatable wing to be operated in three modes: a first orientation mode, a second orientation mode, and a mode in which the wing rotates (called the rotating mode). The apparatus permits the wing to be stowed and used in both fixed-wing flight and rotary wing flight. The apparatus may be a component of an aircraft capable of fixed-wing flight with a fuselage oriented generally in the direction of flight. In the first orientation mode, the wing is generally parallel to the orientation of the fuselage, providing a relatively compact stowage configuration. In the second orientation mode, the wing is generally perpendicular to the orientation of the fuselage. The first orientation mode thus facilitates stowage of the wing during stowed flight of such an aircraft under power of a host aircraft, the second orientation mode facilitates fixed-wing flight, and the rotating mode facilitates rotating-wing flight. The wing may be started into auto-driven (i.e.

  • Patent number: 6190598
    Abstract: A process of making a composite vessel with superior mechanical and aesthetic characteristics includes the steps of: A) preforming a composite thermoplastic shell (e.g., by winding a commingled roving of fiberglass and a thermoplastic material onto a thermoplastic liner) having an opening for access to the interior; B) placing the shell (which may optionally be preheated) into a mold (which itself may optionally be preheated); C) introducing an inflatable bag containing a heater into the shell through the opening; D) heating the inflatable bag to a temperature which is sufficient to render the shell fluid while pressurizing the interior of the inflatable bag; E) continuing step D) until the shell forms against the interior walls of the mold; F) allowing the formed composite vessel to cool; G) removing the inflatable bag; and H) removing the formed composite vessel from the mold.

  • Patent number: 6187054
    Abstract: A method is disclosed for making vascular prostheses from ePTFE said prostheses having a diameter which is larger, and a wall thickness which is smaller than previously achievable using ram extrusion techniques. The method consists of extruding a PTFE tube, finish processing the tube into an ePTFE tube, laterally dilating it by expansion in incremental steps, calendering the tube after each dilating step, while the tube is being maintained at an elevated temperature. Once the tube is dilated it can be sintered with another tube to form a laminate. Alternatively, a wire stent may be joined with one or more tubes, thereby biasing the laminate to a cylindrical configuration.

  • Patent number: 6123523
    Abstract: A device for dispersing gas into molten metal, the device comprising: (1) a pump having: (a) a pump base including a pump chamber and a discharge, (b) a motor, (c) a motor shaft connected to the motor, (d) a rotor shaft connected to the motor shaft by a coupling and (e) a rotor fastened to the end of the rotor shaft opposite the motor shaft, the rotor shaft positioned in the pump chamber. The motor shaft and rotor shaft each have gas-transfer passages and the rotor preferably includes openings to transfer gas from the rotor-shaft passage into the pump chamber. The pump generates a stream of molten metal traveling through the discharge. Gas is introduced into the motor shaft passage and passes into the rotor shaft passage where it is transferred to the rotor and ultimately escapes through the openings in the rotor and into the pump chamber. As the rotor turns it mixes the gas and the molten metal and this mixture travels through the entire length of the pump discharge.

  • Patent number: 6074702
    Abstract: A two-part coating system comprises a first part comprising a blend of an aliphatic polyisocyanate with a non-reactive resin or a liquid epoxide resin and a second part comprising an aromatic polyamine, such that the two parts when mixed together and applied to a surface form a rapid-setting impervious coating. The coating system is suitable for application by spraying using equipment in which the two parts of the system are first combined at the point of spraying, at the spray head. In particular the system may be used to apply an impermeable lining to the internal surfaces of pipelines, for example by means of a centrifugal spinning head.

  • Patent number: 6027685
    Abstract: A system and device for introducing gas into molten metal comprises: 1) a pump having a pump chamber and a discharge, 2) a gas-release device for releasing gas into the discharge, and 3) a flow-directing device to substantially reduce or eliminate the low-pressure zone behind the gas-release device. The pump creates a stream of molten metal through the discharge. The gas-release device, which is preferably a graphite tube, has an end extending into the discharge. Gas is introduced through the gas-release device into the discharge where it escapes into the molten metal stream passing therethrough. The flow-directing device is positioned behind the end of the gas-release device to eliminate the low pressure zone that normally forms there. During operation, the molten metal is diverted around the sides and bottom of the flow-directing device and the gas is dispersed within the molten metal, rather than being trapped in a low-pressure zone.
