Title: Head seal for a mine stopping
Inventor: KENNEDY JOHN M
IPC: E21F17/103
Filed: 1988-11-28
Granted: 1992-06-02
Abstract: HEAD SEAL FOR A MINE STOPPING            Abstract of the Disclosure A mine stopping comprising a plurality of panels adapted to extend in side-by-side relation from the floor to the roof of a passageway in a mine.  Each panel com-prises a first elongate member constituting the lower mem-ber of the panel and a second elongate member constituting an upper member of the panel.  Each member has a web and flanges at opposite sides of the web, each flange having an inturned portion at its outer edge extending generally parallel to its web.  One of the members has a telescoping sliding fit in the other.  The upper member of each panel has a head at its upper end, the head being generally of channel shape in transverse cross section having a web and two flanges.  A sealing member of compressible material pocketed between the two flanges of the head extends up out of the upper end of the upper member for pressure engage-ment with the roof.  The sealing member compresses during pressure engagement with the roof and exerts lateral expan-sive forces against portions of the flanges of the head symmetric about a vertical plane extending in a side-to-side direction with respect to the panel midway between the web of the upper member and the inturned portions of the flanges.  The symmetry of the head results in equivalent lateral expansive forces exerted against the flanges of the head during compression thereby to avoid canting of the panel with respect to the vertical plane.

Title: Photo-processing device
Inventor: MCDONALD FRANK W
IPC: G03B27/46
Filed: 1989-01-10
Granted: 1992-04-28
Abstract: ABSTRACT     An apparatus for forming enlarged exposures of film negatives is provided.  The apparatus is adapted to be coupled to the housing of a conventional photo-processing machine without requiring permanent modification of the conventional machine.  The apparatus includes a pair of magazines, one magazine of which houses a roll of unexposed paper.  The unexposed paper is fed from the one magazine, vertically through the apparatus and into the other magazine.  A mirror placed in the conventional machine, reflects a focussed light beam that has passed through a negative.  The light beam is directed into the apparatus so that it impinges on a portion of the unexposed paper passing therethrough thereby forming an exposure of a negative on the paper. Drive motors automatically advance the paper from the one magazine to the other, upon exposure of the negative on the paper.  A cutter is provided for cutting the paper when a complete reel of negatives has been exposed.

Title: Polymeric casing with textured surface
Inventor: MCGLOTHLIN MARK W
IPC: A61B19/04
Filed: 1989-01-26
Granted: 1993-01-19
Abstract: POLYMERIC CASING WITH TEXTURED SURFACE                 ABSTRACT OF THE DISCLOSURE      A polymeric casing with a textured (matte-finish) surface is manufactured by dipping a form having external contours conforming to the desired shape of the casing in a solution of a polymer dissolved in one liquid, withdrawing the form from the solution to retain the solution as a film over the form's outer surface, applying a second liquid over the surface of the film, the second liquid being one which is immiscible with the first and in which the polymer is insoluble, then solidifying the polymer into a solid film, preferably by solvent evaporation.  Application of the second liquid prior to complete drying of the polymer film causes the resulting film to have a matte finish, which has a lubricous effect without the need for added lubricant powders or liquids, particularly when combined with a mandrel which imparts a similar surface finish to the interior of the film.

Title: Switch-mode power supply
Inventor: LEONARDI GIOVANNI M
IPC: H02M3/28
Filed: 1989-02-02
Granted: 1993-05-04
Abstract: RCA 85,014 ABSTRACT           An input supply voltage is coupled via a primary winding of a flyback transformer to a collector of a chopper transistor switch that operates at a given frequency. During a portion of each period when the chopper transistor switch is conductive, a second switch applies a short-circuit across a secondary winding of the transformer at a controllable instant that causes the emitter current of the chopper transistor switch to increase at a significantly higher rate.  When the emitter current exceeds a predetermined threshold level, a one-shot arrangement is triggered.  Consequently, a pulse is produced that turns off the chopper transistor switch and that maintains it nonconductive for the duration of the pulse.  A flyback pulse produced in a winding of the transformer is rectified to produce a DC output supply voltage. The length of the interval when the chopper transistor switch is conductive is controlled by the second switch in accordance with the level of the output supply voltage in a negative feedback manner for regulating the output supply voltage.

Title: Method and apparatus for controlling tissue growth with an applied fluctuating magnetic field
Inventor: LIBOFF ABRAHAM R
IPC: A61N2/00
Filed: 1989-03-01
Granted: 1993-09-07
Abstract: 2716.004 ABSTRACT     An apparatus and method for regulating tissue growth in vivo are provided. The apparatus includes a magnetic field generator and a magnetic field detector for producing a controlled, fluctuating, directionally oriented magnetic field parallel to a predetermined axis projecting through the target tissue. The field detector samples the magnetic flux density along the predetermined access and provides a signal to a microprocessor which determines the average value of the flux density. The applied magnetic field is oscillated at predetermined frequencies to maintain a preselected ratio of frequency to average flux density. This ratio is maintained by adjusting the frequency of the fluctuating magnetic field and/or by adjusting the intensity of the applied magnetic field as the composite magnetic flux density changes in response to changes in the local magnetic field to which the target tissue is subjected. By maintaining these precise predetermined ratios of frequency to average magnetic flux density, growth characteristics of the target tissue are controlled.
