Abstract: The housing (1) for the gripper device of a robot encloses the drive (4) of movable gripping members (3). There is a free connection between housing interior and operating area of the robot only in the form of slot-shaped openings (7, 7') in the housing wall (8). It is possible by using a suction device to generate in the housing (1) a vacuum which is intended to prevent the passage of rubbed-off particles from the housing interior into the operating area.

Abstract: A hinge for the pivotable connection between the fixed case and the mobile leaf of doors, windows and similar frames, having anti-forcing means and adjustment means. The hinge comprises two supports (1, 2) respec­tively screwed to the case (3) and to the leaf (4), provided with a screw-cover plate (13) which is not removable when the leaf (4) is mounted on the case (3), by virtue of a tooth (41) projecting from the inner face of the plate (13) which abuts against the projecting head of one of the fixing screws (5, 6). In through holes of the supports (1, 2) are seated two bushings (18, 19), each possessing an eccentric hole (20) in which are accommodated the two half-sections (30a, 30b) of a pin (30) which acts as a fulcrum for rotation. By rotating the bushings (18, 19) in the holes (16) of the supports (1, 2) it is possible to adjust the distance between case (3) and leaf (4). Both the holes (16) of the supports (1, 2) and the bushings (18, 19) possess longitudinal groovings (17, 22) and can be reciprocally blocked by a stopper (32) having projecting plugs (34) which are inserted between the groovings (17, 22). The pin (30) cannot be retracted when the leaf (4) is mounted on the case (3), since it possesses an annular enlargement (31) of a diameter greater than that of the holes (16) of the supports (1, 2).

Abstract: On obtient une lumière à ondes courtes en projetant une lumière à ondes longues sur une orbite d'électrons qui emmagasine des électrons rapides afin de provoquer une diffusion Compton inverse pour diffuser la lumière des ondes courtes. La lumière de l'onde longue est réfléchie à répétition de manière à entrer en contact avec l'orbite d'électrons. On peut accroître sensiblement la section de la collision en augmentant le nombre de collisions entre la lumière projetée et les électrons. Une lumière à longueur d'ondes suffisamment courte est obtenue au moyen d'un petit appareil sans que l'on ait besoin d'augmenter significativement l'énergie des électrons.

Abstract: Appareil de contrôle de courant au travers d'un circuit d'une lampe utilisant une dérivation de résistance en série dans le circuit dont une extrémité est connectée à une source de courant et dont la seconde extrémité est connectée à la lampe. Le circuit comprend un comparateur connecté sur la dérivation ou shunt et possède une tension de commutation de seuil telle qu'une tension sur le shunt supérieure à la tension de seuil effectuera la commutation du comparateur vers un état de marche (comme dans le cas où la lampe ne fonctionne pas) et telle qu'une tension sur le shunt inférieure à la tension de seuil (comme dans le cas où la lampe est en circuit et fonctionne) effectuera la commutation du comparateur vers un état arrêt. Dans un mode préféré de réalisation, le shunt est en réalité une portion d'une trace d'une plaque à circuitr imprimé. De manière à compenser les changements de résistance dans le shunt qui se produisent lorsque la température de la trace de la plaque à circuit imprimé change, un circuit de compensation de température est inclus pour maintenir la tension de commutation de seuil dans une relation fixe par rapport à la température du shunt. L'appareil comprend un circuit additionnel connecté au comparateur de manière à diminuer la sensibilité du comparateur aux changements dans la tension d'alimentation de circuit. Dans un mode préférentiel de réalisation, le circuit possède une sensibilité 50 % aux changements de tension d'alimentation. Le circuit peut être fabriqué sous la forme d'un circuit intégré monolithique de manière à améliorer la fiabilité, les coûts et la fabrication.

Title: Method of repair of turbines
Inventor: FRASER MICHAEL JAMES
IPC: B23K20/00
Filed: 1991-06-10
Abstract: A method of repairing stator blades in a turbine comprises the steps of making a pre-shaped insert (20) of a material the same as or compatible with the material of the stator blade (12), the size of the insert is such that it forms a substantial part of the stator blade, the method including the step of removing a piece of material from the stator blade including the damaged part or part that it is required to modify and welding in the new insert. The insert is treated so that at least a part of it is hardened, the hardening may be diffusion alloying or plasma spray and the size of the insert is that the weld line between the insert and the turbine blade is removed from the area of high wear by making the insert larger than would apparently appear necessary, this enables substantial cut-outs to be made on each stator blade which in turn permits of much better access to the stator blades for securing the new insert and/or additional hardening steps such as plasma spray after the insert has been secured to the stator blade.

Abstract: A container (10) for retaining bulk liquid materials is provided having an outer drum (12) forming an enclosed cavity bounded by a base portion (14), upright walls (16) and a top wall (18) including at least one port (20). A liner (26) is disposed within the cavity of the outer drum (12) and is fixably secured to a first bung (32) removably engaged with the port (20). The first bung (32) has a central opening (39) enabling access to the interior of the liner (26) for filling and discharge purposes. When filled with a bulk liquid material, the liner (26) conforms in shape to the shape of the enclosed cavity of the drum (12). The first bung opening (39) is sealed by a second bung member (46) in engagement with the first bung member (32). Upon the emptying of the bulk materials from the drum (12), the liner (28), being thin walled, substantially fully collapses. The first bung member (32) may then be disengaged from the port and the liner (26), in its collapsed state, removed through the port in the top wall (18) of the drum (12). Thus, an easily removable liner is provided which eliminates the necessity of cleaning the drum prior to subsequent use.
