The present invention relates to a safety binding of a boot on a ski which comprises two lateral jaws (2) mounted for movement under the force of an elastic member (5) between a closed service position in which these jaws coact with the sole of the boot (C) and an open position. It also comprises structure (3) interacting with the heel of the ski boot and having a sole grip member (29) mounted for...

A bottle is moved over a sector of a circular path and simultaneously rotated around its longitudinal axis for the opto-electronic inspection of the mouth area for chipping of the glass. The bottle is guided through the beam path of a measuring apparatus on its way over the circular path. A measuring beam passes at an oblique angle to the longitudinal axis of the bottle in the area of the mouth op...

A safety ski binding having a sole plate which is pivotally supported on a ski-fixed pivot pin in a horizontal plane, however, is secured against lifting off from the ski. The sole plate has a front jaw at its front end and a heel holder provided with a housing at its rear end. The heel holder has a sole holder which is pivotal upwardly about a transversely extending axle on the housing against th...

Fibre material is impregnated with an epoxy resin, a photopolymerisation catalyst and a heat-activatable crosslinking agent, and the impregnated material is photopolymerised by exposure to light. It can be fully cured by heating, forming reinforced composite elements.

PURPOSE:To manufacture an electrode rod consisting of a superconductive alloy by one time of melting by interposing an additive element such as Ti, Ta or the like at the boundary part between a copper matrix and high-melting metal and melting the additive element into the high melting metal by a consumable type arc melting method. CONSTITUTION:Plural holes 2 are provided in the axial line directio...

An equipment management system for use with weapon systems on submarines. Such systems involve large numbers of equipment items which require repair, replacement, updating etc in circumstances which may not be conducive to accurate log-keeping of the 'build' state of the system. The invention provides an integrated monitoring system in which each item is provided with a unique bar code which can b...

A pipe assembly for use in production or drilling systems comprises a plurality of pipe members connected together in end-to-end relationship and a plurality of tubular conductor members electrically connected together in end-to-end relationship. The members have co-operating tapered or stepped portions, and/or screw-threaded portions whereby the pipe members support the conductor members in inter...

A rotatable drum (1) carries, and is driven by, a gear rim (3), with bevel toothing (12), via a flexible frustoconical casing (5) which accommodates distortions of the drum and absorbs axial loading resulting from the bevel toothing. Flexing of the gear rim is resisted on one side by the stiffness of the casing (5) and on the other side by a stiffening ring (9).

Polyurethane foams prepared from the reaction of polyester polyol with organic isocyanate have improved flame retardance and dripping ember retardance by incorporation of an additive comprising (1) halogenated flame retardant, and (2) water or alcohol soluble urea-formaldehyde resin.
