Abstract: Procédé permettant de déterminer si une cellule électrochimique est sensiblement complètement chargée ou non. Il consiste à évaluer le taux de variation de l'impédance de la cellule selon les variations de la fréquence, à basse fréquence. En outre, on a prévu un procédé de détermination de l'état de charge d'une cellule électrochimique au moyen d'une comparaison de l'impédance de la cellule à au moins deux fréquences, ou d'une comparaison de l'impédance à moyenne fréquence avec celle à haute fréquence. On a également prévu un appareil de génération de signaux de sortie représentatifs de l'importance des composantes résistive et réactive d'une impédance (30). L'appareil possède un générateur (70) de signaux servant à faire passer un courant alternatif dans l'impédance, et un circuit démodulateur synchrone (88) servant à démoduler un signal de courant alternatif apparaissant entre les deux côtés de l'impédance après passage du courant. Un circuit déphaseur (130, 132, 136, 138, 140) produit de manière sélective des signaux de commande en phase ou dépahsés de 90° par rapport au courant alternatif dans l'impédance, afin de commander le circuit démodulateur de telle manière qu'il produise respectivement les signaux de sortie représentatifs de l'importance des composantes résistive et réactive.

Title: Method for monitoring the door mechanism of an elevator
Inventor: PERALA PEKKA
IPC: B66B5/00
Filed: 2001-10-08
Abstract: The invention relates to a method for monitoring the condition of the door of an elevator and determining its need for maintenance, the door comprising a door mechanism, door panels and a door operator. The signals (10) of the control system of a door in good condition are measured and a set of characteristics descriptive of the operation of the door is generated from them. The signals (10) of the door control system are measured the operation during the opening and closing movements of the door is divided into stages according to which parts of the door are functioning at each stage. From the measured signals (10), a set of characteristics descriptive of the operation of the door is generated. The set of characteristics thus generated is compared to the set of characteristics for a normal operating condition stored in memory, at least in one stage of operation. Based on the comparison of the two sets of characteristics, a diagnosis is performed to determine where and how the operation of the door and its components deviates from normal operation, and the result of the diagnosis is utilized to establish the need for servicing and a servicing date.

Abstract: L'invention concerne un ensemble (10) servant à centrer des courroies (12, 52) et des bandes. Cet ensemble comprend un cadre de support (20) qui est conçu pour être monté sous une courroie ou une bande en mouvement. Un arbre de support droit ou à angle (30) est monté de façon à pouvoir pivoter en son centre par l'intermédiaire d'un montant (32) pouvant tourner à l'intérieur d'une douille (26, 56) sur le cadre de support. Un arc de rotation sélectionné du montant dans la douille (26, 56) est déterminé par un ensemble butée de limitation ajustable qui peut se présenter sous la forme d'une paire de vis d'arrêt. Un rouleau est monté sur chaque extrémité de l'arbre (30). Les deux rouleaux (36, 50) présentent des extrémités coniques (38, 54). Lorsque la courroie ou la bande est décentrée, elle vient en contact avec l'extrémité conique du rouleau du côté vers lequel la courroie s'est déplacée. L'arbre pivote alors autour d'un axe vertical du montant (32) et par conséquent la courroie est ramenée dans sa position centrale.

Title: Method for preparing hyper- immunization serumes against cucumovirus group, tomatovirus group and broad bean wilt virus
Inventor: KHRISTOVA DIMITRINKA P
IPC: A61K39/12
Filed: 1989-11-24
Abstract: The method is applied in plant virusology of ELIZA-kits for quick diagnostics of viruses, causing diseases on plants. It requires a minimum quantity of highly refined virus antigen and the derived hyperimmune serums do not give cross reactions with antigens derived by samples of healthy plants. The method is implemented through immunization under the following scheme: the first two days - in the front eye chamber of rabbits, followed by a muscular injection. On the tenth day - again in the eye chamber, while at the 30th day a busteric venose immunization is carried out. Fourteen days after that, the level of the antibodies is surveyed and the rabbits are deblooded.

Title: Electrolytic etching apparatus and method for marking metal tubes with sequential identification numbers
Inventor: CATANESE JOHN A
IPC: B23H9/06
Filed: 1990-04-18
Abstract: ABSTRACT OF THE DISCLOSURE    An electrolytic etching apparatus employs a continuous stencil imprinted with a sequence of identification numbers and includes spaced spools and upper and lower electrodes defining an etching station located between the spools.  The stencil extends between the spools and is moved by rotatably indexing the spools to position successive ones of the identification numbers over the lower electrode for etching on a successive one of the metal tubes.  A wicking pad is draped over the lower electrode below the stencil and has one end extending into a reservoir of electrolyte also located below the stencil.  The wicking pad draws up electrolyte by capillary action to provide a steady flow of the electrolyte to the portion of the wicking pad located directly below a portion of the stencil located at the etching station.  The upper electrode is mounted for movement toward and away from the lower electrode and the wicking pad and stencil portions.  One tube to be marked is placed between the upper electrode and the stencil portion.  The upper electrode is moved downwardly to press the tube against the stencil portion and thereby against the wicking pad portion and lower electrode. A voltage is then applied to the upper and lower electrodes for causing the electrolytic etching action to occur and mark one identification number on the surface of the tube.
