Patent EP-0257710-A1 (EP)
Inventor: DARRACQ DOMINIQUE
IPC: C25C3/12
Filed: 1987-08-19
Abstract: A bipolar electrode for electrowinning aluminum or other metals by electrolysis of a molten salt electrolyte containing a dissolved compound of the metal to be won comprises an anodic (5) and a cathodic (6) surface which are both preserved during operation by dissolution of small amounts of a substance in the electrolyte (7) which is capable of being deposited on either surface at a rate compensating the corrosion thereof during electrolysis. The anodic surface (5) is for example cerium oxyfluoride and the cathodic surface cerium hexaboride (6), both surfaces being preserved by addition of cerium compounds, such as oxides, fluorides, hydrides etc. to the melt. The cathodic surface may also include titanium diboride on top of or together with cerium hexaboride.

Abstract: The present invention provides a rule based process control system which adaptively controls a process by inducing control rules from the process as the process changes. During process operation data samples from the process are collected, and if a sample is not predicted by the current rules that control the process, new rules are induced from the new sample and previously collected samples by creating a decision tree. The controllable variable having the greatest effect on the goal occupies the highest tree node. New rules are produced from the decision tree which predict process behavior based on the new and old samples.

Abstract: Calipers have mutually pivoted legs (1,2) biased apart by a spring (3), and with a tip spacing adjustable by a nut assembly (6,9; 11,16) on a screw-threaded shaft (4) spanning the legs. This shaft may be pivoted on one leg (1) and be engageable in a detent (8) in an abutment (7) on the other leg (2) with which the nut assembly (6,9) co-operates to set the calipers in the gauging position. The shaft (4) may then be pivoted clear to release the legs, without disturbing the nut assembly, and subsequently restored to the exact gauging position. Alternatively the shaft (4) passes through an abutment (10) and the gauging position is set by a quick-release nut assembly (11) acting against one side of that abutment. On the other side, a nut (16) is then moved into contact before the nut assembly (11) is released. The legs can be subsequently restored to the exact gauging position by bringing the abutment (10) back into contact with the undisturbed nut (16). These principles are applicable to inside as well as outside calipers.

Abstract: Dans la recherche d'une activité maximale des micro-organismes, en particulier, pour obtenir des rendements excellents des bioréactions, deux exigences contradictoires doivent être remplies: il est souhaitable de confiner le micro-organisme pour éviter la contamination des substrats et produits, mais ce confinement exerce un effet défavorable sur les vitesses de réaction qui sont limitées par le transport des substrats et produits à travers la structure assurant le confinement. Conformément à l'invention, on résout cette difficulté en disposant les micro-organismes dans une phase 8e délimitée par une membrane 2e dont la porosité est juste suffisante pour retenir les micro-organismes, mais qui est perméable à tous substrats ou produits consommés ou excrétés durant l'activité desdits micro-organismes.

Abstract: A plurality of carbon fibers (1) are covered with an electrically nonconductive resin (2) so that the individual carbon fibers will not be brought into contact with each other, thereby forming a bundle of carbon fibers. Tips of the carbon fibers are retracted on one side of the carbon fiber bundle to form fine holes (3) that are open to the external side. If necessary furthermore, the retracted tips of the carbon fibers are coated with a permselective membrane, an enzyme or a microorganism, or an electrochemical catalytically active substance (4). The obtained microelectrodes have a small flow-rate susceptibility, undergo less contamination, and can be used as electrodes for measuring dissolved oxygen, as electrodes for measuring ion concentration, as electrodes for bio-sensors, or as reference electrodes.
