Inventor: TONSOR ANDREW J
IPC: E02F3/43
Filed: 1991-11-18
Abstract: Construction vehicles of the type having a pair of lift arms extending from the frame to support a work implement, have generally been restricted to operating one specific tool. The attempt to combine the operation of several different work implements has been met with severe functional restrictions since some work implements have specific requirements not found in the operation of others. In order to provide a lift arm linkage arrangement (25) that incorporates the functional requirements necessary to operate a plurality of work implements (38) while maintaining a simple, yet efficient construction, an electronic control means (90) has been included in the design. The electronic control means (90) includes a plurality of sensors (142, 144) that are operatively associated with the lift (42) and tilt (56) means of the lift arm arrangement (25). The sensors (142, 144) enable the electronic control means (90) to constantly monitor the current position of the lift arms (26) and the work implement (38) and compare them with a programmed sequence of movements. The electronic control means (90) is further able to automatically adjust the position of the lift arms (26) and the work implement (38) in accordance with the programmed sequence.

Patent CA-2103631-A1 (CA)
Inventor: MACKEY JAMES C
IPC: B21D1/10
Filed: 1993-08-09
Abstract: An apparatus for straightening a propeller has an arbor press with two opposed inner surfaces. The opposed surfaces are spaced apart a sufficient distance to allow a propeller to fit between them with one opposed surface extending beyond the second opposed surface. Two pats are mounted on the first inner surface to support the propeller during the straightening procedure. One or both of the pads may be adjustable to more precisely locate the points of pressure that will be applied to the propeller to straighten it. A ram is mounted on the second inner surface to apply pressure to the propeller. A reinforcing ridge may be attached to the outer surface of the arbor press to provide rigidity during the propeller straightening procedure. To allow precision manipulation of the device under water, a floatation collar is fixed to the arbor press or the reinforcing ridge. The floatation has sufficient buoyancy to counteract the weight of the apparatus when under water. To prevent instability in the apparatus when under water, the floatation collar is positioned so that the center of buoyancy substantially coincides with the center of gravity. In one embodiment, a pair of reinforcing ridges and a cover may be used to define a water-tight enclosure. The pair of ridges provide reinforcement and the water-tight enclosure provides additional buoyancy. In operation, a single diver may manipulate the apparatus so that a bent portion of the propeller is between the opposed inner surfaces of the arbor press so that one side of the propeller rests against the pads. The ram is activated and the piston head of the ram applies pressure to the other side of the propeller to straighten the propeller. The apparatus may be manipulated by a single diver and eliminates the need for dry-docking a ship to straighten the propeller thus reducing the cost of repair and speeding up the repair process.

Abstract: DISTRIBUTED LIGHTING SYSTEM WITH FIBER OPTIC CONTROLS ABSTRACT OF THE DISCLOSURE A vehicle lighting system includes one or more central light sources (2a,2b), a plurality of optical loads (4R, 4L,6R,6L,8R,8L,10R,10L,12,14) including headlight lenses (36), an optical fiber network (16R,16L,20,24,28R,28L,30R, 30L) that extends from the light sources to illuminate the headlight lenses and other optical loads, and optical switches (20,32R,32L,34R,34L) and oscillators (18R,18L) that include respective input fibers (52a) illuminated from the light source and output fibers (52b) to respective op-tical loads, and operate by enabling and disabling optical connections between their input and output fibers. The headlight assemblies switch between high and low beams by moving their fibers vertically, and control beam diffusion by moving the fibers parallel to the lens axes, including an automatic diffusion adjustment for a headlight reflec-tion from a vehicle in front. The switches include various mechanisms for moving the input and output fibers into and out of alignment with each other, including a shaped resil-ient sleeve (54), a hinge (70) pivotally joining the fi-bers, an opaque shutter (82) with a transmissive section (86) movable between the fibers, and also a liquid-based switch (100) that relies upon total internal reflection. A feedback mechanism (62,64,66) for some of the switches dims the source lamp when the switch is OFF to conserve energy. The oscillators operate by normally urging an in-put fiber towards an OFF position, at which it actuates a mechanism (114,118,124) that shifts it to an ON position at which the mechanism is deactivated. A failsafe system em-ploys multiple light sources (2a,2b), with each source sharing its light output with the load for another source that has failed.

Title: Blend of flexible coil polymer and thermotropic liquid crystal segmented block copolymer
Inventor: FARRIS RICHARD J
IPC: C08G69/44
Filed: 1992-07-07
Abstract: Novel segmented block copolymers comprising mesogenic (or ''rod'') blocks and flexible coil polymer blocks are disclosed which are especially adapted to be blended with a substantially similar flexible coil polymer matrix to improve the mechanical properties of the flexible coil matric. For example, blends of poly(butylene terephthalate) (PBT) with a liquid crystalline block copolymer, poly(tetramethylene 4,4'-terephthaloyldioxydibenzoate)-b-poly(butylene terephthalate) (LCP-b-PBT) were prepared by precipitation from a common solvent, dried, and melt extruded through a capillary die to produce a monofilament. In all blends, the LCP-b-PBT  domains were less than 0.1 µm in size and ultrafinely and uniformly dispersed. Even though the blends were only moderately elongated into fibrils, interfacial adhesion between the LCP-b-PBT and the pure PBT appeared excellent.

Title: Hydraulically-actuated electronically-controlled unit injector having stroke-controlled piston and methods of operation
Inventor: AUSMAN THOMAS G
IPC: F02M57/02
Filed: 1991-12-23
Abstract: In a hydraulically-actuated electronically-controlled unit injector, the viscosity of the actuating fluid used to actuate the unit injector varies with ambient temperature and affects the magnitude of pressure drops in the actuating fluid circuit. Such variations in viscosity affect the magnitude of the fuel delivery command pulsewidth and/or actuating fluid pressure required for engine startup versus that required for normal engine operation. The present invention provides an improved hydraulically-actuated electronically-controlled unit injector (18) and methods of operation which compensate for variations in the viscosity of the actuating fluid used to hydraulically actuate a piston (88). The stroke of the piston (88) is controlled electronically and/or mechanically in order to achieve an appropriate amount of fuel injection.

Filed: 1994-03-09
Abstract: A cellular mobile communication system includes a plurality of base stations connected to a relay station, each base station having adaptability for coping with change in traffic volume within a relevant cell covered thereby. Each base station includes a variable gain power amplifier for amplifying a pilot signal and a power control circuit for controlling the gain of the power amplifier. The power control circuit controls gain of a pilot signal sending power in accordance with a control signal supplied from a device installed in a relay station for monitoring traffic states of the individual base stations. The relay station issues a command for lowering the power gain for the base station which covers a traffic-concentrated cell while raising the power gain for the base stations covering the neighboring cells, to thereby contract the size of the traffic-concentrated cell. With a smaller number of base stations, communication demand can be controlled over a broad area.
