Patent DE-3922410-A1 (DE)
Title: High-availability drive with redundant rigidly-coupled motors - enables role of failing motor or regulator to be fulfilled by survivor operated under different conditions
Inventor: SCHNEIDERSMANN ERNST-OTTO
IPC: H02P5/00
Filed: 1989-07-07
Abstract: Two motors are coupled together by mechanical gearing and fed with current from a power regulator. If one motor fails, the other motor can maintain the drive to e.g. a cable drum by exerting double torque, or continuing at half speed with double the number of pole pairs in use. Alternatively, three or more motors are geared together with similarly redundant balanced regulators. USE/ADVANTAGE - Operation can be continued even after breakdown of one of the motors or of a regulator.

Patent DE-4005641-A1 (DE)
Inventor: ROGERS WILFRIED DAVID
IPC: E05B47/00
Filed: 1990-02-22
Abstract: In a cable-operated or like latch, primary and secondary locking levers (30 and 31) are arranged for rotation about a common axis which is spaced from the axis of rotation of an operating lever (49) connected to an electric actuator. The secondary locking lover (31) is moved by a control element which is also connected to the latch release lever, and the two locking levers (30 and 31) have a load transfer means (42) acting to transfer a limited load between them. This load transfer means can be a spring (42) located by the pivot mounting for the two locking levers (30 and 31). This enables the use of a manual key operation to disengage the locking lever by overcoming the spring load transfer means even when the secondary locking lover is maintained in its engaged position by the actuator. <IMAGE>

Title: Deposition of quartz glass layer for use in optical fibres - consists of burning silicon-contg. volatile cpds. in flame which is directed at the substrate surface
IPC: B29C48/13
Filed: 1990-08-21
Abstract: A quartz glass preform is made by deposition on a substrate surface of a flame in which combustible Si cpds.  are burned with the addn. of air or O2 pref. just before the cpds. enter the flame. Pref. Si cpds. are alkoxysilanes, silanes, alkylalkoxysilanes, siloxane or silanol. Dopant can be added as volatile cpds. to the flame, e.g. BBr3, B(OCH3)3, borane, ole, corresp. P cpds. or Ge cpds.. The flame is pref. formed on an extended sprayhead and is pref. passed over the deposition substrate which is cooled to a temp. which allows the Si cpds. deposited to form a glass. USE/ADVANTAGE - The deposition method is much simpler to use than current plasma deposition techniques. It does not form glass-soot particles and does not require a glass forming step after the deposition. The yield of Si material deposited is high and so is the deposition rate. There is a clear preferential deposition direction. The process is used for the mfr. of preforms for quartz glass fibre formation.

Title: Control system for sewage treatment plant with single-stage activation tank - using fuzzy logic computer to derive regulating value, e.g. for rate of oxygen addn. from inexact measured and input data
Inventor: WIMMER MICHAEL
IPC: G05D21/02
Filed: 1991-12-12
Abstract: In a new control system for biological processes in a sewage treatment plant with a single-stage activation tank (1), exact or inexact actual values are determined by probes (6, 7), an inexact control values are input manually via an input device (7). The actual and control values are converted to inexact variables (12) in a 'fuzzification' procedure, and are processed in accordance with an inference rule (13). A regulating value is then derived by a 'defuzzification' procedure (14). ('Fuzzy Logic' is a procedure by which a computer derives accurate or precise values from inexact - or 'fuzzy' - input data). USE/ADVANTAGE - Used in partic. for controlling the rate of input of oxygen (16) in aerobic and anaerobic processes in sewage treatment. Allows the treatment process to operate with greatly reduced supervision, and increases the efficiency of the process by enabling the system to cope with inexact input data. This type of data is often the only type available - e.g. the only available assessment of the degree of foaming in a treatment tank may be an operator's judgement of whether foaming is light, heavy or moderate.
