Title: Fiber optic switch
Inventor: ANDERSON JOHN C
IPC: G02B6/35
Filed: 1988-12-21
Granted: 1992-03-31
Abstract: Abstract A fiber optic switch of the moving fiber type and a method of making such switches.  The switch has at least one stationary fiber and a mobile fiber carried by an actuator, preferably a bimorph, the end of the movable fiber being movable between a transmitting position in which the core of the mobile fiber is aligned with the core of the one stationary fiber and a position in which there is no alignment of the core of the mobile fiber with the core of the same stationary fiber.  The stationary fiber is affixed to a smooth substrate surface with a slight flex downwardly between the point at which it is affixed to substrate surface and the end of the fiber which engages the substrate surface.  The actuator is mounted to move in a plane substantial-ly parallel to and above the substrate surface, and the mobile fiber is affixed to the actuator and with a downward flex between the point at which it is affixed to the actuator and the very end thereof which engages the substrate surface. The mobile fiber thus slides over the substrate on movement of the actuator.  The flexed engagement of both fibers with the smooth substrate accomplishes accurate alignment of the cores of the fibers in the vertical direction, and the production of the switch with the fibers flexed as described above does not require the provision of any highly machined components.  Moreover, accurate lateral alignment can be achieved by providing a lateral stop of the substrate surface, which may be in the form of short piece of fiber which has an accurately cleaved end.  The piece of fiber may be moved into a position and adhered to the substrate surface, such as by epoxy, so that as the mobile fiber swings to the aligned position, its engagement with the end of the fiber accurately locates it laterally.  In locating the piece, a drive wave form may be supplied to the bimorph to overdrive the mobile fiber, and the fiber is moved inwardly while the coupled light wave form output is monitored.  The fiber is adhered when the monitored coupled wave form is at an optimum form.  This proced-ure is also capable of providing accurate alignment of the cores of the mobile and stationary fibers without the requirement of highly machined components.

Title: Encased product and method and apparatus for encasing  same
Inventor: TOWNSEND RAY THEODORE
IPC: A23L13/00
Filed: 1989-04-21
Granted: 1995-09-26
Abstract: The encased product of the present invention comprises an elongated flexible casing cylindrically shaped substantially along its length and having opposite end closures.  A product material fills the cavity formed by the flexible casing and maintains the casing in a cylindrical shape.  The cylindrical casing is formed from an elongated strip of flexible material having opposite side edges, the strip being formed into a finished tubular casing with the side edges of the strip within each casing frictionally overlapping and engaging the side edges thereof.  The product is formed by continuously applying an elongated flexible ribbon to the outer cylindrical surface of a stuffing tube at a canted angle with respect to the longitudinal axis of the tube and rotating the flexible ribbon at the point where it is applied to the stuffing tube so that it will wrap around the tube in a plurality of helical revolutions to form a cylindrical casing on the tube.  The adjacent edges of the helical revolutions of the ribbon are frictionally overlapped to one another so as to  form a cylindrical casing and product is forced through the tube from the rearward end to the discharge end and into the cylindrical casing.  The stuffing tube may be a rotating stuffing tube or it may be a stationary stuffing tube.  A ribbon feed device is provided for feeding a continuous strip of ribbon to the stuffing tube.  Moisture is applied to the ribbon to enhance the cohesiveness of the overlapped side edges thereof.

Abstract: A keyboard having a conventional set of alphanumeric keys and special function keys which are actuable by an operator using a finger and a stylus.  The stylus-actuable keys have keypad areas which are less than a prescribed range of areas.  Other keys which have keypads greater in area than a value in the prescribed range are designed for keystroke operation by the operator's finger.  Alternatively, the stylus-actuable keys have center line spacings which are less than a value from a predetermined range of lineal dimensions, while the finger-actuable keys have center line spacings which are greater in value than a value in the predetermined range.          Having been derived from human factors considerations which have been defined for finger-actuable keys, the prescribed range of areas is preferably 100 square millimeters to 162 square millimeters and the predetermined range of dimensions is preferably 12 millimeters to 21 millimeters.  As a result, the footprint of the present invention is smaller than that for a standard sized keyboard while maintaining substantially the same key stroke procedures of a conventionally-sized PC keyboard.  Being suitable for use with a graphical tablet, another embodiment of the invention is made with keys mounted to a surface which is angled between 30 degrees and 90 degrees from the horizontal plane of a desktop.  In an effort to reduce manufacturing costs, the preferred embodiment of the invention is made with membrane type switches using conventional touch panel technology.

Abstract: ABSTRACT OF THE DISCLOSURE           The apparatus for trimming a layer of back fat off a pork shoulder butt comprises a frame as well as a flat, flexible and arcuate cutting blade with two ends respectively attached to a pair of blade holders pivotally mounted onto the frame.  A conveyor, a set of upper gripper belts, and a rotative roller pass the shoulder butt through the blade to trim  off the  layer of  fat.   The  rotative  roller has a diameter gradually decreasing along  its  longitudinal  axis from each end of the roller toward the center thereof to define an annular,  concave outer surface.   This roller is mounted onto the frame adjacent the arcuate blade on the outside of the curve this blade defines but with a distance separating  the  annular  surface  and  the  blade  to  enable passage of the layer of fat between them.  The annular outer surface of the roller is formed with teeth to engage the fat whereby  rotation  of  the  roller  forces  the  shoulder butt through the blade.   The two blade holders are pivoted to adjust the arcuation in the blade and the distance separating the  annular  concave  surface  and  this  blade  to an  inner profile and a thickness of the layer of fat whereby trimming of the latter layer is optimized.

The monitor is located adjacent the fluoroscope for viewing by an operator thereby permitting the operator to observe and/or position the bone in response to images displayed on the monitor.  A crisscrossed grid is located adjacent the image intensifier of the fluoroscope between the bone and the image intensifier.  A CPU compares the successive video images to a reference representation corresponding to a desired or previous movement or pattern of movement of the bone with respect to a second, immobilized bone and any resulting flexure of a joint between the bone and the second, immobilized bone.
