Title: Method for detecting longitudinal tear in a conveyor belt
Inventor: FUKUDA MASAHISA
IPC: B65G43/02
Filed: 1991-04-11
Granted: 1994-12-13
Abstract: Abstract of the Disclosure This disclosure relates to a method and apparatus for automatically detecting any longitudinal tear that is generated in a conveyor belt during its operation, utilizing detectable elements embedded at a plurality of points of the conveyor belt.  An externally installed sensor and a control unit are also provided.  At each of the aforementioned points of embed-ment in the belt, a set of at least two of the detectable ele-ments is embedded, and the control unit is arranged (a) to receive and process signals from the sensor, the signals having a varied intensity corresponding to the number of detectable elements in a given embedment point, (b) to average the intens-ities of a plurality of the signals for the given embedment point, and (c) to judge, on the basis of the average obtained in (b), the presence or absence of breakage of detectable element or elements at the given embedment point.  The above-mentioned arrangement is able to judge whether one of the two detectable elements is broken, and the judgment is not affected by variation of the distance between detectable elements and the sensor.  If breakage of a single detectable element of any set is identified, the affected element may be repaired during an outage of the conveyor.  In this way, breakage of two ele-ments of a point without any longitudinal tear will be eliminated.

Title: Outline compensation apparatus for television receiver
Inventor: WADA MICHIO
IPC: H04N5/208
Filed: 1991-06-04
Granted: 1995-07-25
Abstract: An outline compensation apparatus for a television receiver includes a circuit for detecting outlines of regions of a picture, expressed in a video signal, and a velocity modulation circuit for effecting outline enhancement in response to an output signal produced from the outline detection circuit.  The amplitude of that output signal is controlled in accordance with one or both of a contrast adjustment signal and a sharpness adjustment signal that are used to process the video signal in order to modify the degrees of contrast and sharpness of definition of the picture, respectively.          The operation of the outline compensation apparatus is thereby made to effectively complement any increase or decrease of display contrast and/or sharpness that results from the application of the contrast adjustment signal and sharpness adjustment signal, enabling the user to more easily adjust the television receiver to obtain a clear and natural-looking displayed picture.

Title: Parcel processing system with end of day rating
Inventor: SCHURICHT JURGEN
IPC: G06Q30/04
Filed: 1991-11-01
Granted: 2003-02-18
Abstract: A parcel processing system provides shipping documents required for a number of shipping carriers and/or classes of service. The system includes a keyboard, a scale, a memory, a printer and a processor. The processor receives carrier/service selection signals from the keyboard and transaction data from the keyboard and/or the scale. The processor determines on the basis of the carrier/service selection signal whether to rate or defer a parcel transaction. Data for a deferred transaction is stored in the memory. The foregoing steps are performed with respect to a number of transactions and a number of deferred transactions are combined into an aggregation. The processor receives a deferred rating signal from the keyboard and performs a rating operation with respect to the aggregation of deferred transactions. The printer prints a manifest reflecting the result of the rating operation.

Title: Cache controller
Inventor: SHERMIS J HERSCHEL
IPC: G06F12/10
Filed: 1991-11-26
Granted: 2001-08-28
Abstract: A cache controller is coupled between a central processing unit (CPU) and a memory management unit (MMU). The MMU is coupled to main memory, and the cache controller is further coupled to a cache memory. A cache controller transfers a block of N programming instructions from the main memory into the cache memory. Once this transfer is complete, the CPU begins the sequential execution of the N instructions. Generally concurrently, the cache controller scans each of the N instructions to detect branch instructions. Branch instructions are those instructions which require additional data not found within the block of N instructions previously loaded into the cache. Upon detection a branch instruction, and prior to the execution of the branch instruction by the CPU, the cache controller fetches the branch instruction data from main memory, and stores it within the cache.

Title: Genetic engineering process for the production of s-(+)-2,2-dimethylcyclopropanecarboxamide by microorganisms
Inventor: ZIMMERMANN THOMAS
IPC: C12N15/10
Filed: 1992-07-27
Granted: 2000-11-28
Abstract: A genetic engineering process is disclosed for the production of S-(+)-2,2-dimethylcyclopropanecarboxamide. For this purpose, a new DNA that codes for a stereospecific hydrolase is isolated from a microorganism. This DNA is then ligated in an expression vector, and a hybrid plasmid results, which is used to transform microorganisms. These microorganisms are then able to biotransform the R-(-) isomer in racemic R,S-(~)-2,2-dimethylcyclopropanecarboxamide into R-(-)-2,2-dimethylcyclopropanecarboxylic acid. Optically active S-(-H)-2,2-dimethylcyclopropanecarboxamide is thus obtained.
