Title: Floating pivot hinge and knee brace
Inventor: HARRIS DAVID P
IPC: A61F5/01
Filed: 1987-12-18
Granted: 1991-12-03
Abstract: ABSTRACT A knee brace includes a thigh cuff having inner and outer spaced brace arms adapted to extend along the user's thigh toward the knee, a calf cuff including inner and outer spaced brace arms adapted to extend along the user's calf toward the knee, and floating pivot axis hinges rotatably connecting the inner and outer brace arms of each pair.  The hinge is formed by a pair of juxtaposed hinge plates, each having a pivot face in opposition to a pivot face on the juxtaposed plate, with a concave groove in each of the face.  A pivot bearing ball is confined between the opposed faces and retained in the concave grooves.  A spring, bellville spring, or disk spring biases the hinge plates together when the pivot bearing ball is positioned in the opposed grooves between.  The pivot bearing ball provides a floating pivot axis for hinge rotation of said hinge plates and thereby said braces relative to each other, the ball and concave grooves allowing the hinge plates simultaneously to slide and pivot relative to each other.  The pivot axis f loats between the hinge plates depending on the degree of pivoting and sliding movement in a wearer's knee joint as a result of flexion thereof.

Title: Round baler with continuous bale size monitoring
Inventor: STROSSER RICHARD P
IPC: A01F15/08
Filed: 1988-05-13
Granted: 1991-03-05
Abstract: Round Baler with Continuous Bale Size Monitoring Abstract of the Disclosure A potentiometer is driven by one of the serpentine arm assemblies used to maintain apron tension during formation of a round bale  o that the output of the potentiometer continuously provides an indication of the size of a bale being formed in the baler. A microprocessor based control circuit senses the output of the potentiometer, converts it to a digital value, and compares the digital value with a value representing a desired bale size.  When the two values are equal, the microprocessor computes the number of revolutions of a net feed roll that is required to wrap the bale a preselected number of times, energizes the net feed roll mechanism to feed net into the bale forming chamber, and counts the revolutions of the net feed roll.  When the required amount of net has been dispensed, the microprocessor stops the net feed roll and activates a mechanism to cut the net.  The size of a "full bale" is selected by actuating keys on a control panel.  An offset is automatically provided to compensate for wear in the apron mechanism affecting the "zero" setting of the bale size sensor.  The system permits signalling the operator to steer left or right along a windrow to control bale shape as the bale being formed in the chamber increases in diameter, the signalling rate being non-linear with respect to bale diameter.

Abstract: Abstract of the Disclosure In a printer in which drive transistors coupled to hammer drive coils control energization of the coils within each of a plurality of magnetic print hammer actuators to provide firing of hammer springs associated with the print hammer  actuators,  leakage  of  one  or more  of  the  drive transistors when they are switched off is detected by a testing circuit which flags a fault condition to turn off the driver circuits if the current at a junction common to all of the drive transistors exceeds a predetermined threshold value. This  provides  an  early warning  system  in  which  faulty transistors are routinely detected well before they have a chance to fail and thereafter burn out the associated coil included within a hammerbank of the printer.  The testing circuit which comprises a resistor and an operational amplifier coupled in parallel between the common junction and a power supply terminal is activated by a transistor switch which responds to a test control microprocessor to repeatedly close and thereby test for transistor leakage as well as possible shorted  coils  when  the  printer  is  not  printing.    The microprocessor also repeatedly sequences through the drive transistors to momentarily switch each of them on so that the testing circuit can determine that they and the associated hammer drive coils conduct properly by insuring that a current of predetermined minimum value is present at the common junction. A power transistor coupled to provide rapid current rise when the drive transistors are switched on is also tested for leakage using a second testing circuit, when the printer is not printing.

Abstract: ABSTRACT OF THE DISCLOSURE A method for molding  a  substrate  for  use in supporting  a  magneto-optic recording structure in-cludes the steps of providing a mold having a cavity that defines  a plane and that is designed to form a thin disk-like magneto-optic substrate  and mounting such mold with such plane horizontal and an axis of circular  symmetry  thereof  substantially vertical. Hot  fluid  plastic  flows  from  the center of such horizontal mold  so  that  the  fluid  plastic flows relatively uniformly and radially outwardly from the center of the mold to minimize  azimuthal variations in birefringence.   Such flowing may be bb injection or  compression  molding.    Molding  apparatus  for manufacturing such  magneto-optic substrate includes such mold  and a  support for jpositioning such mold with the  plane thereof horizontal.  Hot fluid plas-tic is injected to the center  of such  mold, as for example from  the vertical  axis of symmetry of such mold.  With the plane of the mold horizontal and the hot fluid plastic flowing radially and symmetrically outwardly from the center  of  the  mold,  the fluid plastic  moves  substantially radially and uniformly through the mold.   The magneto-optic  substrate has relatively  small  azimuthal  variation in birefrin-gence.

Granted: 1993-08-03
Abstract: ABSTRACT (ref Fig 1) Method of modifying an optical waveguide an waveguide so modified A method of structurally modifying a silica monomode optical fibre (4) by launching optical power into the fibre (4) from a Nd:YAG laser operating at 1.064um and raising the temperature of a portion of the fibre (4) by bringing a metal film (12) into contact with a polished half-coupler block (6) to absorb energy from the laser (2).  A structural modification of the fibre is initiated which propagates towards the laser (2) sustained by the optical power.  It provides a means of decommissioning  an optical fibre.  The modified optical fibre (4) has regular periodic damage sites which can be used to form a diffraction grating.  The method may also be used as an optical power limiter to protect optical networks from too high optical power inputs.
