Abstract: Disclosed is a cooled welding electrode with a plurality of fins in the water well, where the fins are tapered between approximately 10 degrees and 45 degrees.

Abstract: A combination of a lid knob and tool having interlocking capability provides an easily removed tool with a handle for applying an added prying, lifting or twisting force to a lid. The vertical cross-section of a sliding interlocking engagement is a dovetail shape. The knob is elongate and the slidable engagement between the tool assembly and the elongate knob positioned horizontally across the top of the lid allows for the selective positioning of the tool at different points on the knob.

Abstract: The present invention relates to a method for working a piece with a machine called a parallel-architecture machine of the type comprising a movable tool-holder table connected to a fixed table by a plurality of legs, the machine being programmed to carry out theoretical cycles of the tools, characterized in that: the fixed table (4) of the machine (1) is fixed relative to a zone of the piece to be worked; measurements are taken of the relative position between a first entity specific to the machine and a second entity specific to the piece; from the measurements previously acquired, the exact position is deduced, in coordinates and in inclination, of the first entity in a frame of reference; the preprogrammed theoretical cycles of the tool or tools are modified according to the exact relative position of the two entities calculated in the previous step.

Abstract: An apparatus (10) for filling at least one cell of an accumulator (12) with electrolyte is described, having a vacuum pump (14) for evacuating the cell of the accumulator (12), and having a filler device (16) for introducing the electrolyte into a fill opening (32) of a cell, and having a container (18) for receiving the entire accumulator (12), the container (18) communicating with the vacuum pump (14) via a connection stub (20), so that the accumulator (12) can be put in its entirety under a vacuum, and the filler device (16) has at least one delivery line (22) for the electrolyte, which line is extended in vacuum-tight fashion into the container (18). The delivery line (22) on each end has a respective filler head (34) with an outlet stub (36), and the outlet stub (36) engages the inside of the fill opening (32) of a cell with play (FIG. 1).

Abstract: Disclosed is a device (10) for forming a plurality of accumulators (14) that are combined to form a group (12) and positioned on a supporting element (60). The poles (16) of the accumulators (14) are arranged on the upper wall (20) of a housing. The device comprises a flat component (22) in the form of a plate, frame, grid or the like. A plurality of pole contacts (24,26) corresponding to the poles (16) of the accumulators (14) are arranged on said component. The pole contacts (24,26) are joined to a central electrical supply connection (32) by means of electro-conductive elements (28,30) that are fastened to the component (22).

Abstract: Resistance welding electrodes and processes of using and of fabricating the same are provided. The electrodes have a base portion and an integral nose portion projecting therefrom, with the nose portion terminating in a welding tip face. The nose portion tapers inwardly between said base portion and said welding tip face with a concave profile taper such as a frustum of a vortical surface. The electrodes used may be made up of a conventional copper material having copper combined with one or more metals selected from the group consisting of chromium, zirconium, cadmium, cobalt, nickel, beryllium, tungsten, aluminum, tungsten carbide, iron, and molybdenum; or, may be made of essentially pure copper. The electrodes may be used in a welding process, which provides for a generally linear increase in current stepping with reduced or eliminated conditioning of the electrodes.
