Abstract: L'invention concerne une amélioration relative à des batteries au plomb-acide. L'amélioration concerne la structure d'une batterie rechargeable au plomb-acide dans laquelle des électrodes (biélectrodes (5)) positives et négatives partagent la même grille ou le même substrat. Selon la présente invention, on empile lesdites biélectrodes les unes sur les autres, lesquelles sont séparées par des séparateurs (11) à mate de fibres de verre très poreux intercalés. Ces substrats positionnés entre les zones à électrodes positives et négatives font office de connexions électriques fixant les électrodes aux bornes de la batterie. On utilise le couvercle du boîtier de la batterie pour exercer une force de compression sur les biélectrodes et les séparateurs.

Abstract: La condensation de Tischtschenko d'aldéhydes est utilisée pour éliminer les aldéhydes de courants contenant une cétone sèche. La condenstion de Tischtschenko est utilisée pour condenser les aldéhydes en esters dont les points d'ébullition sont sensiblement différents de ceux des cétones, simplifiant considérablement la séparation des esters des cétones. Une étape d'extraction organique est utilisée pour obtenir un courant contenant une cétone sensiblement sèche. Une classe particulièrement préférée de solvants d'extraction est sélectionnée dans le groupe incluant le butane, le pentane, l'hexane, l'heptane, l'octane, le nonane, le décane et leurs mélanges. Dans des modes préférentiels de réalisation, la réaction de Tischtschenko est utilisée dans le contexte d'oxydation catalysée en phase aqueuse d'oléfines en cétones. La condensation d'aldéhydes en esters permet une élimination aisée et efficace des analogues d'aldéhydes des cétones désirées.

Patent WO-9006478-A1 (WO)
Title: Interactive electronic thermostat
Inventor: BERKELEY ARNOLD D
IPC: G05D23/19
Filed: 1989-12-07
Abstract: An interactive electronic thermostat operates to communicate with an installer through an audible or visual display and keypad to instruct the installer to perform tasks and enter observations to effect proper connections at the thermostat of heater/air conditioner wires in spite of the absence of labels identifying the functions of those wires. The thermostat requires entry of coded indicia representing operator-observed conditions in the system in response to displayed instructions carried out by the operator. Control circuits are automatically assigned functional tasks in response to the operator-observed conditions entered into the system. Different program routines are invoked depending upon the number of system wires and the type of heater/air conditioner being controlled. Under appropriate circumstances, messages are displayed informing the operator/homeowner that the thermostat is incompatible, or has no advantageous use, with the heater/air conditioner. In one embodiment the installer needs only connect the wires to the thermostat terminals one time; the thermostat reconfigures its internal connection paths in response to installer-entered indicia to assure proper control of the system.

Title: Batch process control using expert systems
Inventor: SKEIRIK RICHARD D
IPC: G06F9/44
Filed: 1990-04-05
Abstract: Batch process (700) control is improved by defining a step endpoint condition (702) in an expert system (900) knowledge base; using the expert system (900) to monitor for the occurrence of the endpoint in the batch process; and triggering a change in a batch process condition when the endpoint is found. Preferably, the expert system (900) and the batch process condition change are implemented as modules which execute under control of timing and sequencing functions in a supervisory control system, and the change affects a setpoint (or other control objective) in a continuous control system. Multiple instances of modular expert systems allow parallel process units to be easily controlled.

Title: Machine translation and telecommunications system
Inventor: CHONG LEIGHTON K
IPC: G06F17/22
Filed: 1991-12-30
Abstract: A machine translation and telecommunications system automatically translates input text in a source language to output text in a target language using a dictionary database (22) containing core language dictionaries for general words, a plurality of sublanguage dictionaries for specialized words of different domains or user groups, and a plurality of user dictionaries for individualized words used by different users. The system includes a receiving interface (11) for receiving input from a sender, in the form of electronic text, facsimile (graphics) input, or page image data, and an output module (30) for sending translated output text to any designated recipient(s). The input text is accompanied by a cover page or header (50) identifying the sender, one or more recipients, their addresses, the source/target languages of the text, any sublanguage(s) applicable to the input text, and any formatting requirements for the output text. The system uses the cover page or header data to select the core language, sublanguage, and/or user dictionaries to be used for translation processing, to format the translated output text, and to send the output to the recipient(s) at the designated address(es). The dictionary database (22) can cumulate an evolve over time by adding new words as scratch entries to the user dictionaries and, through the use of dictionary maintenance utilities, by updating and/or moving the scratch entries to higher-level subdomain, domain, or even core dictionaries as their usage gains currency.
