Title: Interferometric imaging system
Inventor: DULMAN LEV
IPC: G02B9/02
Filed: 1989-11-16
Abstract: ABSTRACT OF THE DISCLOSURE      A quality control system provides for real-time, high-speed, high-resolution, comparison of the three-dimensional form of a sample with that of an exemplar. The quality inspection system includes a sample analyzer, an exemplar analyzer, a comparator, a controller and a position memory. The sample analyzer includes a sample imager for providing an interferometric image of a sample of inspection, a sample scanner for scanning the sample image, and a sample transducer for converting the resulting sample scan into a sample signal representing the three-dimensional form of the sample. The exemplar analyzer similarly includes an exemplar imager, an exemplar scanner and an exemplar transducer to provide an exemplar signal representing an exemplary three-dimensional form for said sample. The comparator provides a comparison signal which identifies the scan times during which differences between the sample signal and the exemplar signal are detected. These signal differences correspond to differences in the fringe patterns of the interferometric sample and exemplar images and thus in form discrepancies in the sample from the exemplar. The comparison signal is used to enable writes to a memory which is constantly receiving position data at its data port so that position data corresponding to signal differences are stored. The position memory can then be read by a host system which can thus acquire a list of locations of potential defects.                                                    ORA*903 PATENT

Inventor: LYKKEN THOMAS G
IPC: G05G5/28
Filed: 1990-05-14
Abstract: Abstract of the Disclosure An apparatus for controlling the position of an operating handle includes a plate for coupling an operating handle to a positionable device such as a hydraulic valve.  The plate includes a detent notch.  An auxiliary lever is movable between a first, engaged position and a second, disengaged position and is maintained in either position by a compression spring which exhibits toggling movement as the lever is moved between positions.  The lever includes means for engaging the detent notch when the lever is in the first position and the handle is thereby retained in a predetermined position.      The apparatus is especially useful on agricultural tractors which tow implements having hydraulically operated functions.  In addition to permitting retention of the operating handle in the neutral position, the apparatus can also retain the handle in an operating position and, in cooperation with a stop mechanism, also permits handle movement to a float position for positioning implements or decelerating high inertia loads.

Patent CA-2019695-A1 (CA)
Inventor: KELLEY REGINALD D
IPC: F16D55/36
Filed: 1990-06-22
Abstract: A tubular hub member receives a shaft and is surrounded by a housing formed by a base section coupled to a cup-shaped closure section. The hub member defines an inlet passage for circulating cooling oil and supports a set of brake discs which interfit between a set of brake plates supported by pins projecting inwardly from the base section. An annular thrust plate is supported by the base section for axial movement and carries a set of compression springs which urge the thrust plate for clamping the brake plates and discs against a pressure plate mounted within the closure section. An annular electrical coil and support body are mounted by screws and spacer sleeves within the closure section, and an annular armature plate is supported by the sleeves for axial movement adjacent the end wall of the closure section. A set of actuating pins extend axially between the armature and thrust plates through the coil body and pressure plate, and the armature plate cooperates with a portion of the closure section to define a variable oil recirculating passage. Axial movement of the armature plate displaces cooling oil into the inlet passage to provide a surge of cooling oil during braking. The pressure plate has passages which are aligned with recesses in the coil body for recirculating cooling oil when the brake unit is positioned with a vertical axis, and diametrically opposed rotatable members provide for manually releasing the brake unit and for automatic reset to inactive positions.

Title: Circuit arrangement for word-by-word serial-to-parallel conversion
Inventor: TURBAN KARL-ALBERT
IPC: H03M9/00
Filed: 1990-07-06
Abstract: ABSTRACT OF THE DISCLOSURE    In a circuit arrangement which converts a serial input bit sequence consisting of successive n-bit words to a parallel word format, a serial-to-parallel converter operates in an unsynchronized manner, i.e., with an arbitrary synchronization offset with respect to the word beginnings in the input bit sequence.  A synchronizing circuit detects the offset of the synchronization and provides an offset signal.  There is connected in series with the converter a circuit which, in accordance with the offset signal, rearranges the bit groups delivered by the serial-to-parallel converter in such a way that complete words are delivered successively to n outputs of the circuit arrangement.  Instead of a synchronizing control circuit for the serial-to-parallel converter, a control circuit connected in series with the converter is used.

Title: Light weight, fast steering riding trowel
Inventor: ALLEN J DEWAYNE
IPC: E04F21/24
Filed: 1991-04-05
Abstract: A compact, lightweight riding trowel for finishing concrete of enhanced maneuverability. A rigid frame is supported above the concrete by a pair of downwardly projecting synchronized rotors, each of which revolves multiple blades frictionally contacting the surface. Lights attached to frame corners provide illumination. The operator manually steers with a pair of primary control levers which tilt the rotors to generate steering forces. The pitch of each rotor blade are controlled manually or electrically, and a cable-driven clutch fork system is activated to vary pitch between minimum and maximum. Each of the tiltable rotor assemblies are driven by gear boxes coupled to the motor through a flexible disk drive shaft. Each gear box is mounted to the frame underside by a pivot steering box.      Parallel lever arms extending beneath the frame in a direction generally perpendicular to the biaxial plane defined by the rotors are deflected by the primary control levers. Each activates elongated torque rods coupled to the gearboxes and tilt the rotors in a plane parallel with the biaxial plane. The torque rods are generally aligned, and for leverage they are braced by a gusset and offset from that axis of rotation defined within the pivot boxes which enables one of the rotors to tilt in an and perpendicular to the biaxial plane. One lever arm controls a torque shaft interconnected with a tertiary linkage system which tilts one rotor in a plane perpendicular to the biaxial plane, and which achieves a mechanical advantage.
