Inventor: BABJAK JURAJ
IPC: C23C26/00
Filed: 1999-06-14
Abstract: Le procédé précipite des additifs sur des germes d'hydroxyde de nickel dans une solution d'ammoniaque. Ensuite, l'introduction d'au moins un additif métallique dans la solution aqueuse crée une suspension épaisse ayant un potentiel de réduction. L'additif est choisi dans le groupe constitué par l'aluminium, le cadmium, le cobalt, l'indium, le fer, le manganèse et le zinc. L'introduction d'oxygène dans la suspension épaisse contenant l'additif à une vitesse commandée préserve le potentiel de réduction de la solution. Au moins l'un des additifs se dissout dans la solution aqueuse en excès de la solubilité en solution de la suspension épaisse pour précipiter l'additif sous la forme d'un hydroxyde sur les germes d'hydroxyde de nickel.

Abstract: A posture chair for heavy duty use in business offices and particularly designed to support exceptionally heavy occupants. In order to support heavy occupants a large number of legs are utilized in the chair base to support the chair, preferably eight. The invention further resides in the use of a support plate, such as a heavy gauge metal disc or washer affixed to the legs of the chair, and contoured to conform to the slope of the legs. The disc or washer, preferably formed of steel, is placed in the preferred embodiment under the legs and welded thereto by weld beads placed in the corner at which each side of each leg engages the disc or washer and also between the disc and hub. This results in an exceptionally strong structure sufficient to support very heavy occupants. These elements of the chair base may also be integral and of cast metal, e.g., aluminum.

IPC: B02C21/00
Filed: 2000-01-04
Abstract: Pour obtenir des sélectivités élevées lors de la séparation de groupes de matières à partir de déchets, avant le broyage ultérieur généralement requis pour des processus de ce type, on arrange, directement après le broyage préalable, une extraction des métaux ferreux, un tamisage grossier, un séchage, une seconde extraction des métaux ferreux, un tamisage fin, une extraction des métaux non ferreux et une extraction des matières lourdes. Ainsi, on obtient le fait qu'avant le broyage ultérieur, toutes les matières dures perturbant le processus de broyage ont été séparées et on peut procéder à un broyage ultérieur par découpe. Grâce au broyage ultérieur par découpe à l'état non pollué et grâce à l'état sec, on empêche la contamination propre du mélange de matières à séparer après le processus de broyage ultérieur et on obtient une sélectivité élevée lors de la séparation.

Title: Computer system for decision support in the selection of diagnostic and therapeutic tests and interventions for patients
Inventor: BATES DAVID W
IPC: G16H10/60
Filed: 1998-08-13
Abstract: A decision support system for the selection of a diagnostic or therapeutic test or intervention, herein called studies, is supported by identifying a relative number of cases in which significant results were obtained in studies having the same indications. In particular, an ordering physician requests a study for a patient and specifies indications for the study, such as symptoms and a potential diagnosis. The number of studies performed, including those on other patients, for which results were significant for the same indications out of the total number of studies performed for the same indications is provided as feedback to the ordering physician. This feedback relates actual patient results to the appropriateness of the study. A decision support system in a health care information management system receives, from an ordering physician, an order for a study to be performed on a specified patient and indications for the study. The received indications for the selected study are used to access a database of result codes for previous studies having the same indications, including studies performed on other patients. A result of the comparison of the selected study and specified indications to the result codes database is then sent to the ordering physician. Decision support may be enhanced by using data extracted from existing scientific literature. In one embodiment, the decision support system is part of a health care management system that supports structured order entry for use by the ordering physician and a structured data entry module for entering result codes into the database.

Title: Multivariate statistical model-based system for monitoring the operation of a continuous caster and detecting the onset of impending breakouts
Inventor: VACULIK VIT
IPC: B22D11/16
Filed: 1999-07-20
Abstract: A method of monitoring the operation of a continuous caster in which a multivariate statistical model is developed using off-line measurements of process parameters representing normal operation of the continuous caster.  On-line process parameters are measured in real time to determine if the caster operation is normal by calculating test statistics on vectors calculated using the multivariate statistical model with input from the on-line process parameters.    The method may advantageously be used to predict breakouts in a continuous caster and allows an operator to take corrective action to avoid such breakouts.  Corrective action may also be taken automatically.

Title: Tracked vehicle steering system with failure detection
Inventor: MISTRY SANJAY ISHVARLAL
IPC: B62D11/10
Filed: 2000-03-21
Abstract: A control system is provided for a tracked vehicle drive/steering system having an engine driven hydraulic steering pump which drives a hydraulic steering motor.  The steering pump is responsive to steering control signals representing a status of an operator manipulated steering wheel. The steering motor provides an input to a differential track drive mechanism which responds to manipulation of the steering wheel and drives left and right tracks to turn the vehicle. The control system includes a control unit which receives signals from an engine speed sensor, a steering motor rotation speed and direction sensor, and the steering control signals. The control unit, when the steering control signals indicate that the steering wheel is turned in a direction opposite to a direction of rotation of the steering motor, generating and saving a first ratio value representing a ratio of the motor speed to the pump speed. Then, if the steering control signal is unchanged after a certain time duration, the control unit generates and saves a second ratio value representing a later ratio of the motor speed to the pump speed. The control unit then calculates a difference value representing a difference between the first and second ratio values, and generates a fault signal if the difference value has a magnitude which is less than a predetermined magnitude.  Thus, the control system generates a fault signal when the sensed signals indicate that the steering pump swashplate position is not changing as it should in response to changes in steering wheel position.
