Abstract: An antistatic additive for polyamide fibres is disclosed, which is a polyoxyethylene having an average molecular weight of 20,000 and a very narrow range of molecular weight, the molecular dispersion index ranging from 1.02 to 1.2. The antistatic mode of action of the additive according to the invention is not completely elucidated, but outstanding and persistent antistatic properties have been experimentally ascertained. The maximum amount to be used is 0.5% by weight with respect to the polymer; higher amounts are in no wise detrimental, but afford no advantage.

Abstract: A percussion fuze for rockets having an impact sensitive assembly with a spring loaded electrical contact. An explosive train has a rotor, a primer in the rotor and a detonator. A first safety inertia device has a cylindrical housing and a first spiral spring arranged in the housing. A ring abuts the first spring and a plurality of first spheres are arranged circumferentially within the ring. A second safety inertia device has a second spiral spring and a cup abutting the second spring. A plurality of second spheres are arranged circumferentially within the cup. A third safety inertia device has an electrical contact guide tube axially displaceable within the cup towards the rocket tip having an annular projection with an inclined surface. A third spiral spring acts on the contact guide tube. The guide tube is retained in the inoperative position by the second spheres arranged between the inclined surface and the inner upper surface of the housing.

Abstract: A method for obtaining synthetic polyamide yarns, more particularly polyamide yarns, is disclosed, which have a high affinity towards basic dyestuffs. The dyeability with basic dyestuffs is improved by adding to the polymerization mass, prior to, or during progress of, polymerization, an aromatic aldehyde having the general formula

WHEREIN M AND N ARE INTEGERS WHICH ARE 1 OR 2, THE GROUP SO3X indicates both a free sulphonic group or such a group salified with a member selected from the group consisting of ammonium ions, alkali metals and alkaline earth metals. Hypophosphorous acid, or an alkali metal salt thereof can also be added to improve the whiteness of the parts of the yarn or fabric which are not to be dyed.
