In the electrode, similar frame portions each have shallow troughs (11) in which a lead grid (10B) is arranged with active material. The frame portions are arranged back-to-back and the active material is covered by a pervious web (23). The frame portions are of plastics and can be formed in one piece subsequently folded to bring them back-to-back. Pref. the troughs are V-shaped. Pref. positive el...

The models of the leather pieces to be cut out are given a codification mark associated with the definition of the contour thereof and the data are recorded in the memory of a computer, the models are placed on a skin while avoiding the defects, the position of said models on the skin is defined digitally and said position is recorded in the computer memory, and thereafter the pieces are cut out b...

This invention concerns a process for making alkanols which comprises contacting a mixture of CO and H2 at a pressure of 500 psig or greater and at a temperature of at least 150 DEG C. with a catalyst system comprising a ruthenium-containing compound and a halogen-free titanium or zirconium-containing compound dispersed in a low melting quaternary phosphonium or ammonium base or salt.

An apparatus for forming composite, fiber/resin components from fibrous, resin-impregnated tape comprises a gantry 11 for positioning a tape applicator head assembly 413 over a mold structure 412, which defines a mold surface of planar or contoured configuration. A control system is employed to control the movement of the tape head 413 over the mold surface 412 comprising a programmable means for ...

In order to make a good knot-free connection, even with highly twisted and thin threads, each of the two threads is introduced from opposite directions into a respective thread-receiving tube (15, 19), in such a way that the respective thread end projects from the thread-receiving tube. Each of the two thread ends is then opened up by means of a respective air stream. For this purpose, for example...

Polyoxyalkylene surfactants for cellular foams can be prepared by reacting a polyoxyalkylene adduct and an esterified unsaturated dibasic acid in the presence of a free-radical initiator.

Metal flake is formed by charging metal particles, liquid and milling material to a ball mill. Metal flake formed, liquid and milling material are removed from the mill at a rate commensurate with the charging rate. The flake is then separated from the milling material.

A monitor device for use in a laser system transmitting laser light through an optical fiber includes a heat-sensitive element which produces an output to monitor the laser system, the element being provided in a predetermined area of the fiber.

Anti-microbial polymeric quaternary ammonium compounds having linear chains which terminate in quaternary ammonium moieties, such compounds being formed by polymerization which is carried out in such a manner that the linear chains thereof are terminated in random fashion, the reaction resulting in the formation of the compounds being a one-step reaction between 1,4-dihalo-2-butene and a mixture o...

A ski binding having both a toe jaw and a heel holder. An electrical circuit is incorporated in the toe jaw and heel holder and indicates whether the ski boot is correctly clamped therebetween. The electrical circuit includes switch contacts located at strategic points on the toe jaw and the heel holder to indicate when the sole of the ski boot is not properly oriented relative to the toe jaw and ...
