Abstract: Le plan CHEDROD pour les barrages actuel, futuriste, révolutionnaire est en principe l'idée et l'image de mon invention en général. Voici en quoi consiste le plan CHEDROD pour les barrages de Centrale hydro-électrique à réserve pompée. Le plan consiste à récupérer l'eau à la sortie des turbines des barrages hydro-électriques et de la faire rentrer ou passer dans des turbines supplémentaires. Les turbines supplémentaires fournissent l'électricité aux pompes pour les faire fonctionner pour remonter l'eau au barrage principal pour le maintenir à son niveau. La récupération d'eau se fait sous forme d'entonnoir. Voici quelques exemples avec dessins du fonctionnement d'une Centrale hydro-électricue à réserve pompée d'après le plan CHEDROD en général.

Filed: 1990-09-04
Abstract: Abstract Self-contained theft and vandalism deterrent system for equipment security including sensors (12) for detecting conditions to which an alarm (24, 26, 28, 50) is responsive.  The analog signals from the sensors (12) are serially delivered by a multiplexer circuit (16) whence they are then directed to a network (20) for conversion to digital signals.  The digital signals are delivered to a micro processor (22) where the signals are evaluated to determine if an alarm condition exists.  The sensing means (12) include sound and  vibration detector  for monitoring the ambient envelope. The micro processor (22) includes built in reprogramming and comparator circuits for varying the level at which a given condition will trigger an alarm response.

Patent CA-2033706-A1 (CA)
IPC: H04L12/56
Filed: 1991-01-07
Abstract: An apparatus and method for effectively managing a switched virtual circuit network by detecting and resolving call routing problems occurring in the routing pattern of the network is provided. Detecting the call routing problems is advantageously achieved by a first process contained in a network management center which has access to all nodes in the network and performs routing table verification for each node whenever there are changes in the routing tables caused by changes in the network, such as an addition of nodes, links and the like. Otherwise, call looping may occur during call set-up as a result of any undiscovered or uncorrected errors in one or more routing tables in the network. Detection of call loops is achieved by the first process through use of a plurality of processing modules that recognizes and excludes in their analysis of the network certain network components that can not be involved in call looping. Identified routing problems are resolved by a second process which provides alternative recommendations as to how best to modify the routing tables in the nodes of the network. A selected one of the alternative recommendations is coupled from the network management center to the nodes in the network for changing the routing tables located at the respective nodes.

Title: Process for producing articles comprising anodized films exhibiting areas of different colour and the articles thus produced
Inventor: JOZEFOWICZ MARK A
IPC: C25D11/22
Filed: 1991-05-09
Abstract: Abstract of the Disclosure A process for producing articles comprising anodized films exhibiting areas of different colour and the articles thus produced.  The process comprises anodizing a surface of an article made of or coated with aluminum or an anodizable aluminum alloys to produce an anodic film having a porous outer layer and a non-porous inner barrier layer between the porous layer and the underlying surface of the metal article. A metal is electrodeposited into the pores of the film to form a semi-reflective layer of metal deposits in the film which generates a visible colour by effects including light interference between light reflected from the semi-reflective layer and light reflected from the underlying metal layer.  A cathodically biased electrode is brought into contact with or close proximity to limited areas of the film to cause the barrier layer to thicken in those limited areas only.  This step in itself may create a pattern of different colours in the contacted and non-contacted areas of the film.  However, further anodization of the surface is preferably carried out before, after, or both before and after, the contact with the electrode, at a voltage which causes the film to thicken below the deposits in the non-contacted areas, but not significantly in the contacted areas.  The contact with the electrode and additional anodization, if employed, causes the optical path that light travels when reflected from the metal deposits and the underlying metal surface to differ in the contacted and non-contacted areas, thus resulting in the generation of different interference colours in these areas.  If desired, the film can be detached from the aluminum article on which it was formed and a very thin layer of metal applied to the exposed surface of the film in order to make a very thin, flexible, planar, patterned article suitable for use as a packaging sheet, or the like.
