Abstract: L'invention concerne un dispositif de retenue d'un ressort de torsion pour piège à mâchoire. Ces ressorts comprennent deux branches distinctes qui se rejoignent en un point de jonction et qui ont chacune une extrémité. Ces branches peuvent se déplacer entre une position ouverte, où les extrémités respectives des branches sont écartées l'une de l'autre, et une position fermée, où elles sont rapprochées l'une de l'autre. Ce dispositif comprend un crochet de retenue monté de manière pivotante par au moins une attache sur l'une des branches du ressort pour maintenir ce dernier en position fermée ainsi qu'un moyen pour éviter le déplacement dudit crochet sous l'effet de la gravité. Un tel dispositif est particulièrement utile comme système de sécurité d'un piège à mâchoire car il permet d'ouvrir les mâchoires du piège avec un minimum de mouvement et sans que les mains soient nécessairement utilisées ce qui représente un grand avantage dans le cas où un être humain se fait accidentellement piéger les mains par le piège.

Title: Method and apparatus for inspissating solid-liquid mixtures by membrane technology
Inventor: HARTMANN EDUARD
IPC: A23L2/74
Filed: 1995-10-10
Abstract: To thicken remaining residues in ultrafiltration or microfiltration for clarifying fruit juices, systems having membrane module groups (1, 2, 3) connected in series are used in the cross flow process with a residue circuit . The groups (1, 2, 3) can be individually switched on or off in succession, depending upon the present thickening gradient of the residue in the residue feed stream. By operating a suitable number of groups (1, 2, 3), an operationally favorable working pressure is kept constant at the membrane modules until as great as possible a desired value of the thickening gradient of the residue is reached. In this way, an improvement of the overall capacity of filtration systems is achieved.

Abstract: L'invention concerne un procédé d'étanchéification d'embouchures de tuyauteries domestiques (6) et de tuyaux similaires d'alimentation de canaux des eaux d'égout (1), dans leurs zones de jonction. Afin de réaliser un raccordement étanche à la pression entre chacun des tuyaux concernés qui débouche dans le canal et la paroi dudit canal, le bord de l'embouchure (9) du tuyau est tout d'abord élargi par fraisage d'un évidement (15a) s'étendant le long de ce bord. Les cavités situées dans la zone du point de jonction, en dehors de la surface intérieure du canal sont alors remplies, depuis l'intérieur de chacun des tuyaux raccordés, d'une matière d'étanchéité (12) durcissant à la température ambiante. Cette matière durcissant à la température ambiante qui se trouve dans le trajet d'écoulement du tuyau à raccorder est ensuite enlevée, ce qui libère ledit trajet d'écoulement. Les cavités qui se situaient auparavant tout autour de ce trajet d'écoulement demeurent alors remplies de la matière d'étanchéité durcie. Une couche de recouvrement est éventuellement appliquée sur la surface intérieure de l'embouchure du tuyau concerné, dans sa zone de jonction.

Inventor: ADSER-LARSEN STEEN
IPC: H05B6/48
Filed: 1995-06-02
Abstract: Lorsqu'on utilise un générateur électrique à haute fréquence pour traiter des articles, il faut ajuster correctement l'impédance du générateur et de l'outil portant l'article à traiter et il faut éviter la formation d'ondes stationnaires dans les lignes de transmission, etc. En plus, il faut pouvoir traiter des articles ayant une taille qui est comparable à la longueur d'onde de la fréquence utilisée et mesurer exactement la puissance transmise à l'article traité. Ces objectifs sont atteints grâce à un procédé qui consiste à mettre un circuit en résonance et à ajuster un rapport de transformation de l'impédance pour avoir des valeurs correctes pour les impédances, ainsi qu'à corriger ces ajustements durant le traitement de l'article. Pour mettre en oeuvre le procédé, on utilise un appareil qui comprend au moins deux impédances variables, ainsi qu'un moyen pour détecter toute déviation par rapport à la résonance et par rapport à l'ajustement correct des impédances. Les deux impédances variables sont de préférence un condensateur qui est variable de façon continue et une self qui est variable de façon continue et la détection s'effectue en surveillant l'apparition d'une onde stationnaire sur la ligne de transmission.

Title: Painting Edge Limiter for a Painting Arrangement with a Short Residence Time
Inventor: ISFORT WOLFGANG
IPC: D21H23/36
Filed: 1995-07-08
Abstract: A coating edge limiter for a coating arrangement with a short dwell time. Color is fed under pressure into a coating chamber formed by a backing roll around which a paper web is guided, a barrier wall, a doctor blade element and sealing blocks located at both ends of the coater. A formatting plate almost completely covers an application zone between the doctor blade element and the barrier wall so that an edge region of the web is sharply delineated and kept completely free of color. In each of the sealing blocks water is supplied via channels to depressions thereby forming a pressure cushion. This pressure cushion prevents the pressurized slip in the coating chamber from flowing out laterally and ensures that the formatting plate is pressed flatly against the web. The coating edge limiter thereby makes it possible to establish very precisely the width of the web to be produced.

Title: Precompression pump sprayer having suck-back feature
Inventor: DOBBS DOUGLAS B
IPC: B05B15/02
Filed: 1997-04-03
Abstract: A precompression pump sprayer has a variable volume suck-back chamber in communication with the discharge orifice for inwardly suctioning any residual liquid away from the orifice and the spin mechanics to avoid clogging as a result of dried accumulated product. In one embodiment a cover on the plunger head is spring loaded and therewith defines the suck-back chamber. In another embodiment the plunger head is spring loaded on the piston stem, such that in both embodiments a top end wall of the suck-back chamber is shiftable relative to the piston stem independently of piston reciprocation. The biasing spring has a spring force permitting a shifting of the end wall to reduce the volume of the suck-back chamber at a peak pressure reached in the pump chamber beyond the threshold pressure required to open the discharge valve, at which time the spring is compressed. The restoring force of the spring causes the top end wall to shift to expand the volume of the suck-back chamber.

Filed: 1997-11-28
Abstract: In order to continuously change the transmission ratio between power-assisted steering mode and emergency steering mode and to maximize the flow of hydraulic oil in the power-assisted steering mode when the steering wheel is rapidly turned, a steering assembly is proposed which uses a common line which bypasses the metering pump, as a supply line for flow amplification during power-assisted operation and as a return line for changing the transmission ratio during emergency operation. This common line is connected to selected supply lines by way of throttles and with corresponding cylinder lines or with all cylinder lines by way of throttles. Steering devices of this type are employed in mobile equipment, in particular in slowly moving vehicles.
