Abstract: Disclosed is a liquid crystal light modulation device comprising a liquid crystal element consisting of at least one liquid crystal cell and a voltage signal input means           . electrically connected with the liquid crystal element, wherein each liquid crystal cell contains a chiral smectic liquid crystal material layer and when a voltage signal is input to the liquid crystal element, the polarization direction of a light transmitted by the liquid crystal element is changed by approx, 90° as compared with the state where the voltage signal is not input to the liquid crystal element.  This enables a change of a light path and an open-close (on-off) operation of a light path at a high speed (optical switching time:  not longer than 1 msec).

Abstract: Truck tractors are connected to their trailers by fifth wheels and several companies manufacture fifth wheel assemblies. The tractors consist of a pair of longitudinally extending beams or rails to which the fifth wheel assemblies mount. Each fifth wheel manufacturer provides several types of fifth wheels, depending upon the type of trucking service being provided. Complicating the situation is the fact that the lateral spacing between the beams will differ. As a result of these variations, different types of mounting brackets have been developed to secure the fifth wheels to the trailer frames. The drop-over bracket fifth wheel mounting assembly consists of an L-shaped angle brace which complements and is slipped over the beam of the tractor; a bracket on its top connects to the fifth wheel. The flat plate method utilizes a thick, flat plate to span across and rest upon each of the beams; it also has a top side bracket. The drop-over method resists longitudinal loads very well but has been found to develop fatigue cracks as a result of lateral and lateral overturn loads. The flat plate method has proved to be a more costly, yet more effective method of preventing fatigue cracking. The present invention combines the positive features of each individual system into a single, and unitary lightweight cast mounting assembly, thereby providing structural homogeneousity which is resistant to fatigue cracking. Since the combined bracket mounts directly to the tractor beams, it can be used from tractor to tractor if necessary, with no concern for the lateral spacing between the beams of a particular tractor.

Abstract: The invention provides a direction sensor and a method of calibrating a direction sensor having a relative heading sensor (14) and an absolute heading sensor (16). The method allows calibration (22) of both the relative heading sensor (14) and the absolute heading sensor (16) at the same time, by taking advantage of the known angular relationship between maxima and minima on the measurement curve of the absolute heading sensor (16). Such maxima and minima are found by rotating the sensors (12-18) through and angle of at least 360°, reading the absolute and relative heading. sensor outputs., at numerous points and comparing each successive output. The relative heading sensor output at the minimum is substracted from that at the maximum, and the difference divided by the known angle to arrive at a conversion constant for the relative heading sensor (14). The center and radii of the measurement curve of the absolute heading sensor (16) may be found by determining the maxima and minima of the curve in two perpendicular directions.

Abstract: A thermoformed thermoplastic truck bedliner has at least one pair of under-cut load restraint pockets forrned by portions of opposed bedliner sidewalls. The pockets are recesced from the sidewall so that a load restraining member such as a 2 x 4 beam may be pressed downwardly to be snapped into engagement with the pockets. The pockets support the boards in a horizontal orientation, with the wide dimension of the board extending from front to back within the liner to give greater board stiffness against loads shifting from front to back. The pockets may be formed in either under the rail bedliners or in over the rail bedliners. In an alternative embodiment, each under-cut pocket is formed in a cross shape such that a board may be positioned horizontally or vertically.

Abstract: A lubricating mechanism for a piston type compressor in a refrigeration system. A cam plate is mounted on a drive shaft for integral rotation therewith in a crank chamber, which is defined in a casing. Pistons are coupled to the cam plate and reciprocate in cylinder bores extending parallel to the drive shaft. Each piston compresses refrigerant gas containing lubricating oil mist and discharges the compressed refrigerant gas from the compressor during rotation of the cam plate. The refrigerant gas is supplied into the crank chamber and is circulated in the casing. The lubricating oil is supplied to various moving parts from a location near the drive shaft. An oil pan is provided outside and to the side of the casing for collecting lubricating oil. A recovering passage connects the oil pan with the crank chamber to convey the lubricating oil from the crank chamber to the oil pan for collection. A guide passage guides the lubricating oil collected in the oil pan to the location near the drive shaft using gravitational force.      By mounting the oil pan on the side of the casing, the oil pan collects relatively less liquefied refrigerant and more oil, and thus improves lubrication of the compressor.

Title: Fail-safe fluid transfer controller
Inventor: STEMPORZEWSKI FRANCIS V JR
IPC: B67D7/36
Filed: 1996-06-11
Granted: 2004-11-02
Abstract: A fail-safe fluid transfer control apparatus has full redundancy in the response to various inputs such as overfill probe signals, ground detection signals, and the like. Independent microprocessor controllers independently evaluate the inputs and each output control signals to close a respective relay when the inputs indicate that fluid transfer may commence. The relays are arranged in series such that both must be closed for a fluid transfer to commence. The control signals from each controller include a static signal and an alternating signal, both of which must be properly output to close its respective relay. Each controller monitors the state of each relay, and discontinues its control signals if either relay appears to be malfunctioning. Each controller runs an different, independently written firmware program to process the detected inputs to prevent a common firmware error. An optical bypass key replaces conventional mechanical keys and transmits an optically encoded signal to the controller for establishing a bypass condition. A preheating circuit is also provided for providing a dynamic voltage supply to standard thermistor probes which may be encountered.
