PURPOSE:To prevent a short-circuit to the positive pole strap caused by falling off of active material and/or piling up of sponge lead by a method wherein spacers, whose positive pole strap side is made to be lower than the negative pole strap side, are provided while the projections, which prevent the spacers from floating and are thinner than the thickness of the negative pole strap, are prepare...

PURPOSE:To avoid additional exposure of copper or a copper alloy in a cutting process by forming necessary parts such as lugs and legs in an unexpanded part, previously removing a grid adjacent to a width cutting part, and forming a covering layer on the expanded plate. CONSTITUTION:A thin plate 1 made of copper or a copper alloy is expanded, and necessary parts such as a lug 16, and legs 17 are f...

An electro-mechanical actuator has a ferrous alloy armature movably mounted within a body chamber. Two axially-spaced permanent magnets are arranged radially inwardly of the chamber and partially define the chamber at the ends thereof. A coil surrounds the chamber. The body is formed of a magnetically-permeable material. Because of the high reluctance of the magnets, each magnet forms a short magn...

A novel, one-pot procedure for the preparation of N-acryloyl- alpha -amino acids involves the steps of: i) reacting a ketone, an ammonium salt, and a cyanide salt in water, optionally in the presence of ammonium hydroxide and a co-solvent, to form an aminonitrile; ii) acryloylating the aminonitrile in aqueous media to afford an acrylamidonitrile; and iii) hydrolyzing with aqueous acid the acrylami...

Procedure and device for cutting pieces of material to order, from a band of material, by using a cutting table equipped with a vacuum installation for holding the band of material in place and a workable, longitudinal and traverse slide on the cutting table, running along the desired cutting lines, which is controlled by a data processor for marking and data control, as the carrier of a cutting t...

Coating metal substrates comprises applying a primer layer (1) by electrophoretic painting, followed by a protective layer against stone impact (2) and a filler layer (3) and then the usual paint layer(s). The novelty is that the compsn. for (2) contains (a) a prepolymer or mixt. thereof based on a urethane-acrylate (I), (b) reactive (meth)acrylate monomer(s) (c) a hardener system and (d) organic ...
