Title: Reaction system for strongly exothermic reactions - esp. methanisation using adiabatic and isothermal reactors in series
Inventor: LOHMUELLER REINER DIPL ING DR
IPC: B01J8/02
Filed: 1977-02-08
Abstract: Strongly exothermic reactions which are catalytically accelerated are carried out by using an adiabatic reaction coupled in series with an isothermal reactor. The two reactors can be placed before or after each other. One scheme involves splitting the incoming feed between the reactors virtually in series. However, the outlet from the isothermal reactor is then fed through the adiabatic reactor. The heat released in the isothermal reactor is used to generate steam. For use in strongly exothermic reactions such as the hydrogenation of CO and CO2. These reactions are virtually uncontrollable in the straight adiabatic reactor while the isothermal reactor requires carefully conditioned steam to achieve favourable reaction products. The system described gives controllable reaction rates without unnecessary complication.

Patent DE-2722518-A1 (DE)
Inventor: SAUFHAUS EGON
IPC: B27N1/02
Filed: 1977-05-18
Abstract: In order to ensure a constantly uniform gluing of the starting material for chipboards, for the chip weight fed to a gluing machine (11) via a belt weigher (1) with load cell (2), a signal is generated representing the actual value of the chip weight and, from this signal, by application to a potentiometer set to the setpoint value of the ratio of chip weight to binder weight, a signal is derived which indicates the binder setpoint value. A metering pump (4) driven by a d.c. motor (3) conveys binder from a storage tank (5) through a line (6) via a valve (10) into the gluing machine (11). A load cell (7) arranged below the storage tank (5) supplies, as a consequence of the reducing weight, a binder actual-value signal which represents the required binder weight and is compared in a comparator with the binder setpoint-value signal. The rotary speed of the drive motor (3) of the metering pump (4) is closed-loop controlled by means of the resulting error signal. Compared with known volume measurements, this process makes possible correct metering, even of binders containing solid components, without fear of the metering device becoming blocked. <IMAGE>

Title: Data identification system for master-slave computer operation - adds identity information to signal before signal path branches to enable automatic transfer of process control without information loss
Inventor: HECHT SIEGFRIED DIPL ING
IPC: G06F11/20
Filed: 1977-11-12
Abstract: The data identification system consists of two data receivers forming part of a process double computer system. The receivers are fed with data from a single source. The system operates in the 'master-on-line' slave in stand-by' mode. The source data passes through an encoder and is identified before being split. Both computers receive identical data. In the event of failure of the first receiver the second computer automatically takes over the process. So that no data is lost during the transfer period, the second computer compares the identification signals of the information last received by the first computer with the last data received direct and of low priority. The second computer then determines with which data to proceed further.
