Patent CA-1309855-C (CA)
Title: Coating device
Inventor: ECKHARD MARTIN
IPC: B05C3/18
Filed: 1988-01-08
Granted: 1992-11-10
Abstract: ABSTRACT OF THE DISCLOSURE    An application-chamber is provided at the doctor-element between the outlet from the chamber containing a coating compound and a strip of material to be coated and  the  counter-roll  carrying  it.   The application-chamber is defined,  in relation to the doctor-element, by  a  baffle-plate  and  is  held  at  a pressure  above atmospheric pressure.   Between the outlet or baffle-plate, the strip of material and the counter-roll, the application-chamber is divided in the direction of the doctor-element  (coating  blade),  and  a  gap  exists between the end of the guide-wall and the coating blade, the width of the said gap being between 4 and 10 mm. This makes it possible to apply a satisfactory coating even with very low surface-application-weights.

Title: Method for underwater acoustic direction sensing
Inventor: FARMER DAVID M
IPC: G01S3/808
Filed: 1988-01-22
Granted: 1991-12-10
Abstract: METHOD FOR UNDERWATER ACOUSTIC DIRECTION SENSING                Abstract of the Disclosure A method of determining the bearing "S" of a signal transmitter relative to a remote signal receiver. A signal pulse having a high signal to noise ratio is transmitted and sampled at closely spaced receivers dis-placed from the transmitter by a distance "D".  Sampled phase components are derived at each receiver by de-riving in-phase and quadrature components of the sampled pulse and by deriving the arctangent of each such com-ponent.  The arrival time of the sampled pulses is mea-sured by applying a least squares Gaussian fit to the modulus or to the amplitude envelope of the pulse sam-ples.  The difference ".delta.t" between the time of arrival of the pulse at each receiver is determined and then the approximate phase difference 2.pi..omega..delta.t between the sampled pulses is determined where ".omega." is the carrier frequency of the transmitted pulse.  The phase difference is then applied to resolve the phase ambiguity of the phase com-ponents and the bearing "S" is then calculated as cos(S) =      where "c" = the propogation velocity of said pulse; and, "r" = the displacement between said receivers.     The method also facilitates correction of errors in the apparent transmitter bearing which are introduced by relative medium movement, in which the signal pulse is transmitted through a medium which moves with a component of velocity "u" perpendicular to the acoustic path between the transmitter and receivers, thereby causing the bearing to appear to deviate from the actual bearing of the transmitter relative to the receivers; and, by small scale fluctuations in sound speed between the transmitter and each of the receivers.

Title: Seal assembly
Inventor: SALT JONATHAN G L
IPC: F02C7/28
Filed: 1988-02-11
Granted: 1993-01-19
Abstract: SEAL ASSEMBLY                 ABSTRACT OF THE DISCLOSURE     A seal assembly for reducing fluid leakage around a circumferential periphery of an annular nozzle stage in a gas turbine engine includes an abradable annular seal member having an annular attachment ring attached to an outer surface, the ring including a radially extending flange portion.  The side of the seal member opposite the attachment ring forms a conventional labyrinth seal with a rotating member extending from a turbine wheel. The nozzle stage includes  an annular portion extending inward  towards  the seal member  and having an axially facing  area  for  abutting  the  attachment  ring.   The member depending  from the nozzle stage in conjunction with  the  attachment  ring  forms  a  radially  slidable seal.   Tabs  are provided attached to one side of the seal member for engaging the depending member from the nozzle  stage  for  holding  the  seal member  in  sliding contact against the nozzle stage.   The  radial  sliding relationship  between the  seal  assembly and the nozzle stage permits differential radial movement between the attachment ring and the nozzle stage to thereby maintain the  sealing  relationship  under  differential  operating temperatures.

Title: Photo imaging system using two-dimensional optical lens array
Inventor: HARDY JAMES A
IPC: G03B27/50
Filed: 1988-03-18
Granted: 1992-09-08
Abstract: PHOTO IMAGING SYSTEM USING TWO DIMENSIONAL            OPTICAL LENS ARRAY ABSTRACT OF THE DISCLOSURE A photo imaging system includes a two-dimensional lens array for forming an image of an object on a receptor element.  The lens array includes a number of optical glass fibers which are mounted in rows between supporting plates so that each row is adjacent to a plate.  This causes the optical fibers to be supported in a parallel manner to reduce distortion which is caused by unsupported bending or flexing of the fibers.  Since the lens array and receptor element remain fixed relative to each other during image formation, formation of a complete image of the object is achieved by providing a lens array having a sufficient number of fiber rows.

Title: Electrical connector with secondary wedge lock and protected integral latching arms
Inventor: O'GRADY THOMAS R
IPC: H01R13/627
Filed: 1988-05-19
Granted: 1992-04-21
Abstract: Abstract Electrical Connector With Secondary Wedge Lock And Protected Integral Latching Arms An  electrical  connector  including  a  basic connector   shell   having   two   female   terminal receptacles  inserted  through  one  end  and  being lockingly engaged with the interior of the connector shell  by means  of  tabs  from  the  shell  interior extending  into  mating  openings  in  the  terminal receptacles, with a secondary locking wedge member inserted  through  the  opposite  end of  the  shell, causing the tab-opening locking engagements to be further  locked  together  by  compressive,  wedging forces directed towards the central interior of the shell.  The secondary locking member at its top has two side, flexible legs having laterally extending locking protrusions which engage into mating cavities in  the  side,  interior  of  the  shell,  effectively locking the secondary locking member into the shell. The wedge locking member and its interfacing with the interior structure of the shell forms an interior rectangular  structure  over  which  is  placed  a compressive sealing gasket.  The rearmost structure of   the   secondary   locking   member   forms   in configuration a "T" which mates with two, opposed "L" shaped corner members on the interior of the shell, two laterally spaced openings being formed thereby for the insertion of the male electrical connectors to engage with the female terminal receptacles.  Two integrally  formed  latching  arms  are  provided  on opposed  sides  of  the  exterior  of  the  shell  for latching and unlatching the shell from male terminals on, for example, a fuel injector.  Pairs of flanking, protective, side flanges are provided on the exterior of the shell extending over a substantial portion of the sides of the latching arms, protecting them from inadvertent contact  from  the  sides,  helping  to prevent inadvertent disengagement of the connector from the fuel injector.

Abstract: SLIDE CALCULATOR FOR BACKGROUND LIGHTING               ABSTRACT      There is disclosed herein a slide calculator for determination of flash-to-background distance for studio photography when using color filters over the flash. By use of the calculator, known factors, such as lens f-stop, film speed, flash guide number (GN), background density (darkness), desired degree of color (including shades of gray and white) saturation of said background and filter exposure factors can be used to determine the working distance of a background-flash with a color filter over the flash.  An electronic flash meter is not required. The calculator includes a front panel with a window-like aperture and a back panel. Two slide members are positioned and movable between the front and back panels. Indicia is provided on the front panel and is generally arranged adjacent the window like aperture. Indicia is also provided on the slide members and is arranged for exposure at the window. In connection with distance to be determined, the indicia on the slides and the indicia adjacent the window are arranged in a predetermined manner and relationship so as to permit the distance to be calculated. Photos or slides showing how various color filters will photograph in various shades provides a visual aid in choosing a color and shade and is used in conjunction with the slide calculator to determine the flash-to-background distance required to reproduce said color and shade. 5 Claims, 4 Drawing Figures
