Title: Control of carbon balance in a silicon smelting furnace
Inventor: DOSAJ VISHU D
IPC: C01B33/025
Filed: 1991-11-12
Abstract: CONTROL OF CARBON BALANCE IN A SILICON SMELTING FURNACE              ABSTRACT           The present invention is a process for the carbothermic reduction of silicon dioxide to form elemental silicon. Carbon balance of the process is assessed by measuring the amount of carbon monoxide evolved in offgas exiting the furnace.  A ratio of the amount of carbon monoxide evolved and the amount of silicon dioxide added to the furnace is determined.  Based on this ratio, the carbon balance of the furnace can be determined and carbon feed can be adjusted to maintain the furnace in carbon balance.

Title: Modular neural network process control system with natural language configuration
Inventor: SKEIRIK RICHARD D
IPC: G06N3/04
Filed: 1991-07-25
Abstract: A modular neural network process control system and method with natural language configuration allows neural network functions to be easily configured and operated without programming expertise.  Neural networks are provided as standard modules in a modular control system architecture. Each module has a storage area for holding module parameters and for holding a pointer to a neural network procedure. The procedure carries out the real time training and prediction functions of the neural network, and can be pointed to by multiple neural network modules. For neural network parameters, such as weight matrices, requiring large storage, the module storage also holds a pointer to a neural network parameter storage area. Partially defined neural network functions are presented to the user as a template, and the user completes the specification of the neural network functions by entering data into the template. Each type of partially defined function corresponds to a generic neural network procedure which is used to execute the module function. Or, neural network specifications can be accepted in a limited set of substantially natural language constructs, which are parsed into symbolic specifications. A neural network procedure is created by combining code fragments needed to implement the symbolic specifications.

Title: Interfacially synthesized reverse osmosis membranes and processes for preparing the same
Inventor: TOMASCHKE JOHN E
IPC: C07C61/00
Filed: 1992-07-16
Abstract: Abstract of the Disclosure Water permeable reverse osmosis membranes are prepared by interfacially polymerizing on a microporous support an essentially monomeric polyamine reactant having at least two amine functional groups per reactant molecule, and an essentially monomeric amine-reactive polyfunctional single ring cycloaliphatic acyl halide having fewer than six carbon atoms per ring and having on the average at least about 2.2 acyl halide groups per reactant molecule.  The polymerization is preferably carried out in the presence of a monomeric amine salt, which increases the flux rate of the resulting membrane. In addition, an aromatic polyfunctional acyl halide may be used in conjunction with the cycloaliphatic acyl halide in order to increase salt rejection rates.  Preferred cycloaliphatic acyl halides are 1-cis, 2-trans, 3-cis, 4-trans-cyclopentane tetracarboxylic acid chloride, 1-cis, 2-trans, 3-cis, 4-trans-cyclobutane tetracarboxylic acid chloride and 1-cis, 2-trans, 4-cis-cyclopentane tricarboxylic acid chloride.  The preparation of novel alternating cis/trans isomers of cycloaliphatic polycarboxylic acid halides is carried out using metal salts of the all-cis polycarboxylic acids.

Filed: 1992-09-02
Abstract: In a system for controlling a gear ratio of a multi-step geared or continuously variable automatic transmission of a vehicle based on determined parameter indicative of operating condition of the vehicle including a driving resistance, the driving resistance is calculated in an equation in which motive force - driving resistance =  vehicle mass x acceleration using the law of motion. In the first embodiment, the calculation is carried out, without using a torque sensor, by applying an adjustment for torque consumption by a device such as an air conditioner and a torque loss caused by braking. In the second and third embodiments, the driving resistance is calculated using a torque sensor. Thus, with the arrangement, the driving resistance can be accurately determined applying appropriate adjustment, a gear ratio to be shifted is properly determined in any traveling condition including hill climbing.

IPC: A44B11/25
Filed: 1992-09-23
Abstract: ABSTRACT OF THE DISCLOSURE In an inflatable seat belt unit of the present invention, a bag-like belt 2b is maintained in band-like shape in normal case.  When a tongue 5 is engaged in a buckle unit 4 for putting the belt on, a gas flow hole 4a and a gas flow hole 5a are aligned, and a gas flowing passage is formed, while the gas flow hole 4a and the gas flow hole 5a are shut off by caps 11 and 12 in normal case. Because a gas generator 9 is not operated in normal case, the inflatable seat belt unit fulfills the function to restrain the occupant in the same manner as the conventional type ordinary seat belt unit.  In an emergency, high pressure gas is generated from the gas generator 9, and the generated gas ruptures the caps 11 and 12 and enters the bag-like belt 2b.  As the result, the bag-like belt 2b is instantaneously and perfectly inflated and developed, and the occupant can be perfectly received by the inflated and developed bag-like belt 2b.
