Patent CA-2182021-A1 (CA)
Title: Roller for a guide system for continuously cast metal
Inventor: PLESCHIUTSCHIGG FRITZ-PETER
IPC: B22D11/128
Filed: 1995-01-19
Abstract: The invention is directed to rolls for a strand guide stand for producing strands in the form of slabs, blooms, and billets resulting in a central running of the strand in the strand guide stands and accordingly in highly reliable casting - even at casting speeds of up to 6m/min. This high level of casting reliability is achieved by means of strand guide stands in which the rolls have a slightly concave surface line (cambering of the strand) resulting in the surprising elimination of the weaving motion of the strand in the direction of the narrow sides and accordingly ensuring that the strand runs centrally with reference to the center axis in its main direction of progress.

Title: Data buffer monitoring apparatus in a disk drive system
Inventor: ANDERSON STEVE
IPC: G06F3/06
Filed: 1995-03-10
Abstract: A data buffer monitor apparatus which monitors the space availability in WRITE buffer and the number of sectors available for transfer in the READ buffer and generates the OK TO TRANSFER signal. The data buffer monitor apparatus includes a READ buffer monitor, a WRITE buffer monitor and a transfer controller. The READ buffer monitor monitors the total number of sectors stored in the READ buffer, the number of sectors in the READ buffer available for transfer to the host and generates a READ OK TO TRANSFER signal if the sectors for a requested READ operation are stored in the READ buffer. The WRITE buffer monitor monitors the total number of sectors in the WRITE buffer and generates a WRITE OK TO TRANSFER signal if the WRITE monitor determines that a requested WRITE operation can be performed. The transfer controller in response to either the READ OK TO TRANSFER signal being generated by the READ buffer monitor if a READ operation has been requested or the WRITE OK TO TRANSFER signal being generated by the WRITE buffer monitor if a WRITE operation has been requested generates an OK TO TRANSFER signal indicating the requested READ or WRITE operation transfer of sectors to and from the disk drive system may be performed by the disk drive.

Inventor: LINN CARL PRESTON
IPC: C12Q1/68
Filed: 1996-11-08
Abstract: The present invention provides methods for detecting amplified oro unamplified nucleic acid target sequences at increased temperatures by changes in fluorescence polarization. The decrease in fluorescence polarization associated with hybridization of oligonucleotides at higher, more stringent, temperatures is overcome by including a double-stranded DNA binding protein in the assay. At elevated temperatures, the double-stranded DNA binding protein restores, and often enhances, the magnitude of the change in fluorescence polarization associated with single- to double-stranded conversion of an oligonucleotide probe or primer.

IPC: G06F9/42
Filed: 1996-12-02
Abstract: In summary, the present invention is a multithreaded computer system having a memory that stores a plurality of objects and a plurality of procedures. Each object has a lock status of locked or unlocked, and includes a data pointer to a data structure. The system uses a global object locking procedure to service lock requests on objects that have never been locked as well as objects that have not recently been locked, and uses a local object-specific locking procedure to service lock requests on locked objects and objects that have been recently locked. The global object locking procedure has instructions for changing a specified unlocked object's lock status to locked, and for creating for each specified object a local object locking procedure. The local object locking procedure includes a lock data subarray for storing theobject's lock data and instructions for updating a specified object's stored lock data. A lock data cleanup procedure, executed when the system's garbage collection procedure is executed, releases the local object locking procedure of a specified object if the object has not been recently locked.

Inventor: KING RANDAL DANIEL
IPC: C23C18/31
Filed: 1992-11-18
Abstract: A stabilized spray displacement tin plating process of copper printed circuit innerlayers is disclosed for the manufacture of multilayer printed circuit boards.  During prolonged use of spray tin plating, the plating solution becomes saturated with cupurous thiourea complex which precipitates interfering with spray nozzles and other mechanical components.  The tin plating solution is stabilized by removing portions from the reservoir before saturation is reached, selectively precipitating the thiourea complex, and returning the remaining solution back to the reservoir. The precipitated cupurous thiourea complex is redissolved in acid and either disposed of by conventional waste treatment or the acid solution can be electrowinned to reclaim copper and oxidize thiourea to form a more acceptable acid solution for waste treatment. Preferably,the thiourea is isolated from the anode during electrowinning, so that the acid thiourea solution formed may be used to partially replenish the tin plating solution in the reservoir. By such periodic removal of the complex, the plating bath is stabilized and its useful life is extended dramatically.

Title: Method and apparatus for implementing a communication service contract using cell arrival information
Inventor: CORBALIS CHARLES M
IPC: H04L12/56
Filed: 1996-03-06
Abstract: To simplify the service decision made in a queue based digital switch, a method and apparatus is introduced that makes service decisions based upon the history of incoming cells. The apparatus includes a minimum service rate circuit that monitors the rate of arriving cells. The minimum service rate circuit tests the arriving cells to determine if they are in conformance with the minimum service rate of a service contract. The minimum service rate circuit may use a continuous state leaky bucket algorithm or virtual scheduling algorithm as specified in the CCITT Recommendation I.371 document to determine if a cell is in conformance with the minimum service rate of the service contract. When a cell arrives that conforms to the minimum service rate, the minimum service rate circuit notifies the server and the server serves the queue associated with the connection.

Abstract: A method and apparatus for efficiently rendering and printing bands of image information defined by a page description language. The invention estimates the print time for each print band sufficiently in advance to control a page-oriented output device print engine. In a first embodiment, the present invention controls the speed of the print engine for each page to be printed, based on a "rendering cost" or rasterization time estimate for some or all of the bands on each page. In a second embodiment, the present invention controls the speed of the print engine for each band to be printed, based on a "rendering cost" or rasterization time estimate for each band. An additional aspect of the present invention is that the print engine can be sped up for empty or sparse pages or bands, thus improving overall print speed. A third variation of the invention controls the speed of the print engine between groups of bands ("subpages") when the engine speed cannot be changed for each band, but can be changed for spaced-apart bands or groups of bands. In each case, the print speed is matched to the rendering speed to eliminate or reduce the need to pre-render, compress, and decompress page description language print information. By rendering and printing each band of data "on the fly", memory requirements are reduced. Print speed is optimized by providing band print data "on the fly" while maintaining the highest print engine speed possible for the complexity of particular data.
