Abstract: A clamping mechanism for mounting a monitoring device to an electrical cable includes a core assembly formed by a plurality of laminations secured together and arranged in a generally rectangular configuration.  A spring spanning the core is anchored at one end to the core at a point near the housing of the monitoring device and at the other end is attached to a bridging member affixed at the opposite end of the core near the housing.  This allows the spring to expand less as it transverses the bridge in order to accommodate different power cable diameters.

Title: Code division switching scheme
Inventor: SHERMAN MATTHEW J
IPC: H04B1/707
Filed: 1997-11-12
Granted: 2001-10-30
Abstract: Each user signal of a communications network is encoded using a narrowband traffic code and a wideband cover code for transmission to a signal relay (e.g., a communications satellite) in one of a plurality of uplink signal beams. The signal relay receives all of the user signals in the different uplink signal beams and processes them to re-transmit them in different downlink signal beams to their different appropriate destinations. The narrowband traffic codes and wideband cover codes are selected to encode the individual user signals in such a way as to permit the switching processing of the signal relay to be implemented at the beam level (e.g., individual components processing multiple user signals at a time) rather than at the user level (e.g., one switching circuit for each user). For example, in one embodiment, all user signals within the same signal beam are encoded using different narrowband codes and thesame wideband cover code, while user signals in different signal beams are encoded using different wideband cover codes. The present invention enables a reduction in the volume and cost of switching equipment within the signal relay. Furthermore, much of the switching processing can be implemented at intermediate frequencies (IF) using conventional, relatively inexpensive radio frequency (RF) components.

Title: Tiled, flat-panel displays with color-correction capability
Inventor: GREENE RAYMOND G
IPC: G06F3/14
Filed: 1997-03-25
Granted: 2002-01-29
Abstract: The present invention features a tiled, flat-panel, color display (20) that has a color-correction capability (24). The display is a tiled mosaic of individual display tiles (22), such as AMLCDs. Column and row inputs that are typically provided for a single display tile system are distributed over a plurality of display tiles. The color purity is achieved for the display by sorting the tiles into groups, matching their color coordinates, and correcting non-uniformities optically (e.g., by using a graded neutral density filter (28) having a grading function being the inverse of the brightness distribution non-uniformities) and/or electronically. Then, each individual tile in the mosaic is color-corrected via a multiplexed controller/driver circuit (12).

Abstract: A post production processing application receives and manipulates document print images, in particular to integrate postage printing and accounting into the document finishing, without the need for a specialized postage printing system. The post production processing application may run on a main frame, together with the application(s) that generate the document print images, or on some other computer platform. The post production processing application calculates postage for each document and interacts with a postage metering functionality to obtain digital tokens. Each token includes an encrypted cipher for use in validating applied postage indicia. The mail processing system uses the tokens to generate postage indicias, containing the ciphers, during the subsequent document printing and finishing processes. The meter functionality may reside in software (e.g. as part of the post production processing application), in a meter device associated with and connected to the platform that runs the post production processing application or in a remote data center in communication with that platform. The mail processing system may print the indicias on the documents or on envelopes that will carry the documents.

Title: Method & apparatus for electrically braking a motor
Inventor: ROTH-STIELOW JORG
IPC: B60L7/10
Filed: 1998-09-24
Granted: 2008-12-16
Abstract: Converter-powered electric motors are often braked by electrical means. For this purpose the electronic converter that powers the motor is so controlled that the motor, when in generational operation, sends energy by way of the converter into an electrical braking resistor additionally connected to the converter, and this energy is there converted to heat. In order to avoid overloading the electrical braking resistor, an additional electronic or thermo-mechanical protective device is customarily provided. To simplify the arrangement, it is proposed in the present invention to provide as an electric braking resistor one made of a resistive material with a conductance that decreases progressively as the temperature rises through a certain range below the maximal acceptable operating temperature of the braking resistor. As a result, the power that can be accepted by the electrical braking resistor is made self-limiting, so that the braking resistor is protected against overheating.

Title: Method and apparatus for adjusting the boundary surface between two controllably flowing and mutually separable solutions and for conducting both solutions out of the separation part
Inventor: NYMAN BROR
IPC: C22B15/00
Filed: 1997-04-29
Granted: 2006-06-06
Abstract: The invention relates to a method for adjusting the boundary surface between the two mutually separable solutions in liquid-liquid extraction at the discharge end of the separation part and for preventing the aeration of the solutions when discharging them from the separation part, so that the overflow height of the settled, lighter organic solution is maintained constant. In order to adjust the boundary surface in between the mutually separable solutions, the overflow height of the heavier aqueous solution is adjusted by conducting the settled aqueous solution from down upwards through tubular elements, in which case the height of these overflow pipes can be adjusted. The aeration of the solutions when discharging them from the separation part is prevented by conducting the solutions into transfer pipes through covered, shaft-like weir boxes that are deeper than the discharge end. The invention also relates to an apparatus whereby the boundary surface between the solutions is adjusted and the areation prevented.

Granted: 2006-11-07
Abstract: A process for beveling the tip of a medical catheter is described. A catheter blank is mounted on a mandrel normally with the mandrel tip extending beyond the tip of the catheter to be beveled. The mandrel and catheter blank are inserted into a previously heated mold having a passage therethrough through which the mandrel passes. At a portion of the mold at which the terminus of the catheter is to be formed, a constriction is provided through which material (flash) may pass from the mold volume to the outside of the mold. The material is permitted to cool sufficiently such that when the mandrel and catheter are withdrawn from the mold, the flash tears and separates from the catheter at the point of the constriction formed between the mold and the mandrel.
