Title: Coupling assembly
Inventor: KINNEY GERALD R
IPC: F16L23/16
Filed: 1990-06-29
Abstract: Abstract of the Disclosure A Coupling Assembly The invention relates to a coupling assembly for connecting two members.  The coupling assembly prevents excessive radial movement, scrubbing of the coupling members, and leakage of fluid being transferred through the coupling.  The coupling assembly includes a tube end having a pair of spaced apart annular beads defining a groove for a resilient seal ring seated in the groove and the other member defined a bore for receiving the tube end.  A guide ring substantially centers the tube in the bore whereupon a clamping assembly releasable connected to the tube is clamped to the other member securing the tube in the centered position while permitting limited axial movement of the tube.

IPC: A61F9/00
Filed: 1990-08-23
Abstract: A pair of rotatable optical image deflector assemblies is disclosed which are detachably mounted via an adapter bracket to a conventional eye testing apparatus.  Each optical image deflector assembly has a fixed light reflecting optical element, and a pivotal reflecting optical element.  The optical image deflector assembly directs light onto a peripheral area of a visually sensitive or functional area of the retina which is normal to the central field of the retina.  The pivotal optical element scans a pre-set field expanding test chart and projects an image thereof to the visually sensitive or functional area of the retina.  The optical image deflector assembly is usable in making prismatic eye glasses to expand the normal central field of view of a person suffering from retinitis pigmentosa or hemianopia.  The prismatic eye glasses refract images from a field outside the normal central field of view within and along the peripheral edge of the visually sensitive central area of the retina for expanding the normal central field of view.

The amplifier is mounted  to the  coupling  piece with the aid of elongate  conductive pins  which also serve to connect the sensor leads to  the amplifier.
Patent CA-2030110-A1 (CA)
IPC: H04N1/32
Filed: 1990-11-15
Abstract: A facsimile device and a maintenance and control method thereof are disclosed, which enable a reduction in time  load  and  economic  load  incurred  by users  and  a maintenance and control station with respect to maintenance and control of the facsimile device.  The facsimile device includes   a trouble   type   determining   circuit   for determining, when trouble occurs, whether or not the type of trouble can be handled by the users.  A control circuit controls a sending/receiving circuit so that,  when the trouble  type  determining  circuit  determines  that  the trouble  cannot  be  handled  by  the  users,  the  trouble information is sent to a facsimile unit of the maintenance and control station.  Therefore, even when trouble occurs that cannot be handled by the user, the trouble can easily be quickly dealt with, resulting in a reduction in time load and economic load on the user and the maintenance and control station with respect to the maintenance and control of the facsimile device.

Title: Method and apparatus for wood chip sizing
Inventor: BROWN ROBERT A
IPC: B07B9/00
Filed: 1991-02-12
Abstract: A system and process for sizing wood chips to provide a flow of wood chips which are acceptable for feeding to a digester of a pulping system.  A flow management screen station is rovided which divides an incoming unacceptable flow (F0) into two fractional flows (F1, F2), neither of which is acceptable for feeding to the digester.  One of the output flows from the flow management screen is concentrated in oversized and overthick chips compared to the incoming flow.  The other output flow is concentrated in undersized chips and particles compared to the incoming flow.  The output flows from the flow management screen are then fed to second and third screens (16, 14) which separate "overs" and "unders" from the respective flows to provide acceptable flows to the digester.

Title: Sunlight readable display structure
Inventor: TANNAS LAWRENCE E JR
IPC: G09F13/00
Filed: 1992-01-10
Abstract: SUNLIGHT READABLE DISPLAY STRUCTURE                   ABSTRACT OF THE DISCLOSURE    Sunlight  readable  display  structure  includes  a layered structure formed of a reflective element, an LED light source, a colored filter, a legend plate, and a liquid crystal  shutter.    The  reflective  element  is positioned behind the LED light source.  The light source is formed of an LED array having a diffusion medium disposed in front of the LED array for scattering light when energized.   The liquid  crystal shutter permits displayable information on the legend plate to be viewed only when the LED array and the liquid crystal shutter are energized.  The reflective element and the diffusion medium reflect and scatter incident sunlight which is passed through the liquid crystal shutter, legend plate and colored filter back through the colored filter and legend plate and out the liquid crystal shutter.   The colored  filter is preferably selected to have certain spectral transmission characteristics.  As a result, the contrast of the displayable information on the legend plate is  enhanced and is unaffected by washout to a viewer located in the area of incident sunlight.
