A cover (24) for a welding wire container (10,12) is shown, having an upper surface (26) provided with a slot (32) through which the welding wire (16) can be withdrawn from the container, and having spacing means (34) which define an inner portion (36) and an outer portion (38) of the slot such that welding wire extending through the inner portion of the slot is held spaced from welding wire extending through the outer portion of the slot.

Cover for welding wire container

A wire guiding liner, in particular welding wire liner, has a plurality of roll holders (10) which are displaceable with respect to each other, each roll holder (10) holding a plurality of rolls (30). The angular displaceability of a roll holder (10) with respect to the adjacent roll holder (10) is limited such that when the wire is fed through the liner, it always touches exclusively on the rolls (30) even when the liner is bent to its maximum curve, such that the wire while being inserted always hits the next roll (30) at an angle that will push it towards and maintain it guided at the centre of the liner.

Wire guiding system

A composition comprising a) an epoxy resin; b) a hardener; and c) a stabilizer comprising a metal-containing compound, the metal-containing compound comprising a metal selected from the Group 1 1 -13 metals and combinations thereof, and wherein said composition contains a non-halogen flame retardant is disclosed.

Metallic compounds in non-brominated flame retardant epoxy resins

The invention relates to a halogen-free flame retardant, which can be obtained by polycondensation of monomers containing phosphorus with monomers which form esters. The monomer which contains phosphorus is an adduct of 9,10- dihydro-9-oxa-10-phospha-phenanthrene-10-oxide (DOPO) and ring-substituted DOPO derivatives on unsaturated carboxylic acids. Monovalent and multivalent alcohols are used as the monomers which form esters. The flame retardant has a mean molecular weight of greater than 20,000 at a mean degree of polymerization Pn of at least 55 and is preferably used to produce polyamide fibers and polyester fibers in the melt spinning method.

Halogen-free flame retardants

The present application relates to a wire guiding liner, in particular a welding wire liner, having a plurality of guiding bodies (10) which are pivotable with respect to each other around a defined pivot axis (16), wherein at least one biasing means (30) is provided which acts between adjacent guiding bodies (10) so as to push them apart while still allowing the liner to bend under pressure.

A wire guiding liner, an particular a welding wire liner, with biasing means between articulated guiding bodies

A flame-retarded epoxy resin composition which comprises an epoxy resin and a curing agent as the essential components and further contains a phosphorus-containing flame-retardant polyester resin obtained by the condensation or polycondensation of the reactive phosphorus compound represented by structural formula (Ι). Since the epoxy resin composition is enhanced in flame retardance by using the phosphorus-containing flame-retardant polyester resin serving as a halogen-free flame retardant, the composition little evolves toxic gas in burning and exhibits excellent moldability. Further, the products obtained by curing the composition are excellent in heat resistance, water resistance, chemical resistance, flame retardance, soldering resistance, moisture resistance, and tracking resistance and so on.
