Title: Spot size modulatable ink jet printhead
IPC: B41J29/38
Filed: 1994-05-04
Abstract: A spot size modulatable, drop-on-demand type ink jet printhead for producing grey-scale images on a substrate.  The ink jet printhead includes a main body portion having an ink-carrying channel extending therethrough and a piezoelectric actuator coupled to the ink-carrying channel.  A spot size for droplets to form when striking the substrate after ejection from the ink-carrying channel is selected  and  a  look-up  table  translates  the selected spot size into a time period during which a  voltage  pulse  is  to  be  applied  to  the piezoelectric actuator by an associated switching structure to cause the ejection of a droplet of ink capable of forming a spot having the desired size. An associated control circuit causes the switching structure to initiate application of the voltage waveform, determines whether the voltage waveform has been applied to the piezoelectric actuator for the time period and terminates application of the voltage  waveform  upon  expiration  of  the  time period.  The control circuit includes a sequencer which selectively asserts or deasserts at least one control signal to the switching structure, a timer which  instructs  the   sequencer  to  initiate application of the voltage waveform and determines time elapsed since initiating application, and a comparator which compares the time period produced by  the  look-up  table  and  the  elapsed  time determined by the timer.

Title: Method and Apparatus for Parallel Processing in a Database System
Inventor: HALLMARK GARY
IPC: G06F9/46
Filed: 1994-09-09
Abstract: The present invention implements parallel processing in a Database Management System. The present invention provides the ability to locate transaction and recovery information at one location and eliminate the need for read locks and two-phased commits, The present invention provides the ability to dynamically partition row sources for parallel processing. Parallelism is based on the ability to parallelize a row source, the partitioning requirements of consecutive row sources and the entire row source tree, and any specification in the structured query language (SQL) statement. A Query Coordinator (802) assumes control of the processing  of an entire query and can execute serial row sources (804, 806). Additional threads of control, Query Servers, execute parallel operators. Parallel operators are called data flow operators (DFOs). A DFO is represented as SQL statements can be executed concurrently by multiple processes, or query slaves. A central scheduling mechanism, a  data flow scheduler, controls a parallelized portion of an execution plan, and can become invisible for serial execution. Table queues are used to partition and transport rows between sets of processes. Node linkages provide the ability to divide the plan into independent lists that can each be executed by a set of query slaves. The present invention maintains a bit vector that is used by a subsequent producer to determine whether any rows need to be produced to its consumers.  The present invention uses states and a count of the slaves that have reached these states to perform its scheduling tasks.

Patent CA-2174737-A1 (CA)
Inventor: FALLER DOUGLAS V
IPC: A61K38/00
Filed: 1994-10-13
Abstract: This invention is directed to compositions and methods containing physiologically stable compounds of butyric acid salts, derivatives of butyric acid, or combinations thereof, for the treatment of neoplastic and other diseases and disorders including leukemias, lymphomas, sarcomas, carcinomas, squamous cell carcinomas, neural cell tumors, seminomas, melanomas, neuroblastomas, germ cell tumors, undifferentiated tumors, mixed cell tumors, metastatic neoplasias, neoplasias derived from pathogenic infections and other malignancies. Butyric acid derivatives include analogs homologs including next adjacent homologs and compounds based on a part of the butyric acid moiety. These compositions are useful prophylactically and as a treatment for directly eliminating transformed cells by inducing cellular differentiation. These same compounds also indirectly eliminate transformed cells by reducing the expression of MHC and non-MHC antigens of the surface of transformed cells which enhances their identification and subsequent removal by the patient's immune system. In addition, these compositions are useful for decreasing multi-drug resistance activity of the cell which, in conjunction with conventional chemotherapy, results in greater concentrations of chemotherapeutic agents within the cell, thereby enhancing there effectiveness, and for the treatment and prevention of gastrointestinal disorders such as colitis, inflammatory bowel disease, Crohn's disease, and ulcerative colitis.

Title: Rinsing procedure for automatic washing machine
Inventor: BADGER GORDON GEORGE
IPC: D06F33/38
Filed: 1996-07-26
Abstract: A laundry washing machine in which water is conserved by replacing the conventional deep rinse by a series of spray rinses. Each spray rinse utilises a predetermined quantity of water which is sprayed directly at the clothes load while the load is rotated, thereby allowing the rinse water to pass straight through the clothes load, removing soil and/or detergent from the clothes on its way. The amount of water used in each spray rinse is determined from a first "sense rinse" cycle in which the volume of water required to totally saturate the clothes load is found. In each subsequent rinse, a proportion (preferably from about 50% to about 100%) of this value is used.

Patent CA-2183103-A1 (CA)
Inventor: SILVESTRINI THOMAS A
IPC: A61F9/007
Filed: 1995-02-06
Abstract: La présente invention concerne un dispositif et un procédé de correction d'anomalies optiques de l'oeil humain. Elle implique l'utilisation d'une sonde électrochirurgicale présentant des configurations physiques spécifiques. Selon ce procédé, il convient d'utiliser de préférence un dispositif radioélectrique à haute fréquence d'électrodissection ou d'électro-ablation. L'étape initiale consiste à constituer au moins un site d'accès au volume cornéen derrière la membrane de Bowman. Ce site est placé de préférence sur la surface antérieure de la cornée, qu'il traverse pour s'arrêter derrière la membrane de Bowman. La sonde électrochirurgicale est ensuite introduite dans le site d'accès et, en fonction de l'anomalie visuelle à corriger, activée de manière à ajuster le volume des membranes du stroma cornéen par ablation ou dissection. La forme du volume disséqué ou retiré par ablation dépend de l'aberration à corriger. Par exemple, si l'aberration optique qu'il faut atténuer est une hypermétropie, on peut procéder à une réduction circulaire du volume cornéen sur la périphérie extérieure de la masse cornéenne. Dans d'autres cas, comme pour le traitement de l'astigmatisme, on peut réduire des sections plus petites du volume cornéen. Dans certains cas, on peut couper la membrane de Bowman pour que la courbe de la cornée puisse s'adapter après l'ajustement du volume cornéen. Ces coupures dans le relief peuvent être radiales, circulaires, semi-circulaires ou avoir toute autre forme adaptée à l'ajustement requis.
