Title: Method and apparatus for winding and forming field windings for dynamo-electric machines
Inventor: BURCH JERRY C
IPC: H02K15/085
Filed: 1997-09-09
Abstract: A method of winding stators having skewed slots and an apparatus for performing the method. The method includes the steps of positioning a stator (108) in a stator winding machine wherein the winding machine includes a winding spindle (18) having a wire exit aperture (110). Wire is fed through the wire exit radially outwardly for placement on the stator while the winding spindle is simultaneously moved in rotating and reciprocating movement to direct wire into the slots (112) and around the ends of the teeth (114) of the stator.      The wire is fed at a predetermined rate from a feed mechanism (78) located upstream from and mounted for movement with the winding spindle. The rate at which the wire is fed may be varied depending on the position of the winding spindle in a winding cycle and the desired position for placement of the wire within the stator.

Title: An air distributor or collector
Inventor: PALMER EDWARD G
IPC: F24F13/068
Filed: 1997-09-17
Abstract: An airflow apparatus for controlled distribution or collection of low velocity air. To collect air, a fan (40) draws air (51) from the proximal end of an elongated tube (20) disposed in an air-environment (50). Airflow through the tube's distal end is controlled by a tube terminator (30). The tube terminator may be an air impermeable cap completely preventing distal-end airflow. Tube (20) receives air all along its length through openings (21) in its wall. The wall is more air permeable per unit surface area of said wall, at its distal end, than at its proximal end. Wall permeability progressively increases from the proximal end to the distal end. A preferred tube type has a substantially constant rate of air ingestion at all points along the wall. Reversal of the airflow direction in the tube converts the air collector into an air distributor.

Title: Welding gun for projection welding
Inventor: DERDOWSKI RONALD A
IPC: B23K11/14
Filed: 1997-10-20
Abstract: A welding head for projection welding wherein the spring which biases the electrode is initially preloaded to exert a significant biasing force on the electrode to maintain it against a stop to define the normal fully extended position of the electrode. The spring of the welding head is also initially precalibrated to exert an accurate predetermined biasing force on the electrode when the electrode is depressed inwardly so as to effect compression of the spring by a predetermined distance, which latter distance is of very small magnitude. The welding head is disposed in engagement with overlapping sheets so that the electrode is engaged with the sheets in alignment with a projection thereon, and the electrode is depressed through said predetermined distance so that a uniform predetermined biasing force is applied to the electrode and hence to the projection weld area.

Title: Apparatus for communicating diversity signals over a transmission medium
Inventor: FARRIS ROBERT L
IPC: H04B10/12
Filed: 1999-05-03
Abstract: An apparatus for communicating, over a single transmission medium, two signals of substantially the same center frequency. The apparatus offsets in frequency one of the signals by combining the signal with the signal from a local oscillator. The apparatus then transmits the two signals, one offset from the other, as well as the signal from the local oscillator to allow for recovery of the two signals with a precise correction for the offset. In particular, the transmission medium is an optical fiber and the two signals are a main RF signal and a diversity RF signal received, respectively, by a main element and a diversity element of a diversity antenna system. The invention is of use, for example, in providing to a microbase station a main RF signal and its diversity RF signal received at a diversity antenna system remote from the microbase station and connected to the microbase station by an optical fiber.
Patent CA-2271340-A1 (CA)
Inventor: ZURBRUEGG HEINZ ROBERT
IPC: A61B17/82
Filed: 1999-05-06
Abstract: An improved method of reducing and stabilizing the sternum after a sternotomy includes fixing a staple (42) at the anterior surface (26) of the sternum adjacent to each outlet (30) for trans-sternal wire sutures (24). The staples (42) are applied to the sternal halves (20, 22) to reinforce the bone adjacent to the suture outlets (30) so as to prevent the suture from cutting into the bone. As each suture loop (24) is tightened to adapt the sternum, the suture loop (24) abuts the staples (42) adjacent the suture outlets (30). The staples (42) are deformed under force applied by the suture loop (24) to indicate that the loop has been tightened to an optimum degree. A sterile surgical staple gun (40, 40') is employed to install the staples (42) in the sternal halves (20, 22). A kit (80) for performing the improved sternal reduction procedure includes a pre-sterilized staple gun (40, 40') loaded with surgical staples (42), as well as suture/needle assemblies (82). The staple gun (40') can be provided with a recess (90) or notch at the lower edge of the front wall (88) of the staple gun (40') in order to be able to position the staples closer to the suture (24) or suture outlets (30).

Title: Robust technetium removal method and system
Inventor: SNYDER THOMAS S
IPC: B01J47/08
Filed: 1998-03-11
Abstract: The invention provides a method and processing system (10) for removing both anionic and cationic technetium complexes from an aqueous solution by adjusting the pH of the solution to greater than approximately 2, and directing the solution into an integrated resin and electrochemical plating device (30). The integrated resin and plating device (30) has a resin bed (32) or resin membrane in which is disposed one or more cathodes (38), and one or more anodes (36). A potential generator (34) produces at least a 1 volt potential between the cathodes (38) and anodes (36). As the solution passes through the resin (32), the technetium complexes are absorbed onto it. When a sufficient concentration of technetium complexes is adsorbed, the plating process can alternatively be driven to plate out the technetium onto the cathodes, or to collect various species in system anolytes/catholytes.

Abstract: Laying out a paragraph using a layout services library. An entire paragraph is defined as a single text run. The text run is laid out by substituting glyphs for the characters of the text run and then positioning the glyphs. After the text run is laid out, the length of the text run is compared to the line length. If the length of the text run exceeds the line length, then the text run is divided into a parent text run and a child text run. If justification is enabled, then the parent text run is justified. If a child text run is created, then the length of the child text run is compared to the line length.  If the length of the child text run exceeds the line length, then the process is repeated until the length of the last child text run does not exceed the line length. A layout services library provides text processing functions which support the paragraph layout and the justification.
