Title: Process for the regulation of the amount of heat which is fed to the bottom of an extraction column.
IPC: B01D3/42
Filed: 1980-04-15
Abstract: A process and apparatus are provided controlling the heat input of an extractive distillation column. The bottom of the column is heated with a major stream of thermal energy which is either slowly varying in time or controlled by the amount of starting material mixture and with a minor stream of thermal energy which is controlled by sensing the thermodynamic state in the upper half of the column during the process. The major stream can provide about 90 percent and the minor stream about 10 percent of the heat fed to the column. The minor stream can be controlled by the temperature at one point in the upper half of the column, by the temperature difference at two points in the upper half of the column or by gas chromatographic analysis of the extract material concentration near the top of the column. The process allows one to keep a low concentration of the extract material in the raffinate.

Title: Information processing system for error processing, and error processing method.
IPC: G06F11/10
Filed: 1980-07-29
Abstract: A data processing system for error processing and an error processing method, which system includes a main memory (M), an information processing unit (A), an error processing unit (EP) and an alternate memory. When an error arises in a portion of the main memory, corrected information is stored in the alternate memory. Then, under the control of the error processing unit (EP), the alternate memory is employed instead of the malfunctioning portion of the main memory. The alternate memory is adapted to be used only when the error is a fixed error or a burst error, in order to avoid a system shut-down caused by fixed- and soft-errors or burst- and soft-errors which occur during information processing. The alternate memory, therefore, is not used in a case where the error is a soft error. This imparts an additional advantage in that the size of the memory is reduced.

Title: Brake gear for electric rolling stock
IPC: B60L7/02
Filed: 1981-03-12
Abstract: PURPOSE:To simplify a constitution by a method wherein the pressure of an air brake pipe is transmitted to a stopping brake pattern generating circuit through an air pressure-voltage transducer, and an electric brake pattern is obtained. CONSTITUTION:The air pressure of a brake pipe TFA is controlled by manually operating a brake valve BV of an air transducer BP or exciting a braking solenoid B and a taking-off solenoid R. The air pressure of the brake pipe TFA is supplied to a brake cylinder BC through a cut-off solenoid valve PAMV. An air pressure- voltage transducer TD, on the other hand, converts the air pressure of the brake pipe TFA into voltage, and forwards it to a field chopper device FCH through a stopping brake pattern generating circuit SBPC and a comparison amplifier AMP. A current relay CR excites the cut-off solenoid valve PAMV when a fixed quantity or more of generating braking force is generated, and cuts off air brake.
