Abstract: ABSTRACT OF THE DISCLOSURE A precision lens mounting assembly which includes a plurality of lens cells and a plurality of lenses which correspond to the plurality of lens cells. The lens cells have an annular shape. Flexure means are disposed within the inner diameter of the lens cell which hold the lens in a predetermined spatial relation at a datum temperature to the lens cell. The flexure means return the lenses to this predetermined spatial relation following temperature excursions away from, then back to, the datum temperature. The outer diameter of the lens cells in the assembly are all substantially equal and substantially concentric about the optical axis of the lenses they hold. The upper and lower surfaces of the lens cell each have three or more precision to the optical axis of the lens and have a predetermined spatial relation to the apex of the lens. Selected ones of the lens cells can be rotated, translated or moved axially with respect to the other lens cells into the lens assembly to correct for astigmatism, coma or spherical aberrations, respectively. Adhesive means are provided to hold the plurality of the lens cells together.

Title: Hydraulic control circuit for a master cylinder with multiple limit position
Inventor: KINZENBAW JON E
IPC: A01B63/14
Filed: 1987-06-19
Granted: 1992-01-28
Abstract: Abstract of the Invention An hydraulic circuit includes a master cylinder and at least one slave cylinder connected in series circuit.          An auxiliary discharge conduit with a solenoid-actuated valve is provided to selectively permit the master cylinder to extend its full useful range after the slave cylinders are fully extended.   Under normal operation the valve is closed so that the cylinders may extend together. When the slave cylinders reach full extension, the main control valve is kicked out of its detent and the system locks up in that position.  If the operator wants the master cylinder to extend further to a second limit position, he opens the solenoid-actuated valve and again operates the main control valve to extend the master cylinder.  The system insures that the main control valve will be released from the detent position when the slave cylinder is fully extended at the first limit position of the master cylinder.

Abstract: Abstract Disclosed herein is a method and circuit useful in the testing of integrated circuit chips.   On-chip test circuitry is provided at a selected location on an IC chip and energized while the chips are still mounted on a lead frame member, wound on reels and heated in an oven.  Advantageously, the continuous lead frame member may be a tape automated bond  (TAB bond)  flexible circuit which is adapted for gang bonding to a large plurality of ICs before being wound on reels.         In a preferred test circuit embodiment, the conductive on-off  state  of  digital  address  circuitry  is  controlled  by applying a test signal potential to an input test pad and through a fuse to a common test circuit function.   This junction is in turn connected between a transistor and diode in a series control network which is operative to control the conductive state of the address circuitry.  This network enables the input test pad to be used  as  both  a  test  signal  input  connection  and  a  ground connection for the IC test circuit.

Abstract: METHOD AND APPARATUS FOR LOADING     ARTICLES INTO A CONTAINER Abstract of the Disclosure A method and apparatus for loading articles into a container.  The articles, in the form of a side-by-side stack of small trays or boxes, are conveyed along a conveyor and are discharged into a bin, which is mounted for pivoting movement between an article receiving position, in which the base of the bin is located at an acute angle to the horizontal, to a dis-charge position where the base is disposed generally vertical.  The stack of articles received within the bin is supported against a movable end wall, and clamp-ing means is provided to clamp the stack laterally against a side wall of the bin, as well as clamping the stack against the base.  With the stack clamped in the bin, the bin is then rotated to the discharge position and the movable end wall is moved to a release posi-tion.  The bin is then lowered to lower the stack into a container, and on release of the clamping mechanism the stack is discharged into the container.

Abstract: ABSTRACT      A method for producing metal by the reduction of a metal halide by a reducing metal agent capable of continuously producing homogeneous metal of high purity.  In the method, particles of the same metal as the metal to be produced are charged into a reaction vessel and the metal halide and the reducing metal agent both in vapour form, are ejected upwards into the reaction vessel from its lower portion to form a fluidized bed of the metal particles in the vessel. The reducing reaction between the two vapours takes place on the surface of the metal particles at a temperature below the melting point of the metal product and at a pressure below a vapour pressure of each of the reducing metal agent and the metal halide at that temperature, resulting in depositing and growing the metal product on the surface of the particles.
