Columbium is provided with a barrier on the surface thereof by forming an oxide layer of columbium, complexing the oxide layer with a Group III metal, and then oxidizing the Group III metal, for example, by treatment with phosphoric acid.

To reduce the danger of electrical shock in two-wire non-grounded electrical systems, the leakage current from line L1 to ground is balanced by an injected current from ground to line L1, and similarly the leakage current from line L2 to ground is balanced by an injected current from ground to line L2. In this way, the leakage current from line L1 to ground cannot pass through a human body from ground to L2, since the leakage current form a closed current loop.

The invention relates to a safety device for protecting against any overpressures which may prevail in an enclosure, which device is constituted by a deformable membrane applied in fluid tight manner over an orifice connecting the inside of the enclosure with the outside, and by a perforated holder for the membrane, situated between the latter and the inside of the enclosure. The invention finds an application in the protection against fluid overpressures is the tanks of a methane-tanker.

A vaccine composition and method for the immunization of ewes against EAE (enzootic abortion in ewes) based upon inactivated Chlamydia sp. propagated in cell culture. The invention also relates to a method for the preparation of said vaccine and an intermediate therefor.

Water-resistant articles such as automobile surfaces are protected against soiling from asphalt undercoating, paint overspray and the like, by applying a pre-coat film of polymer that is readily flushed off with water after the soiling exposure is terminated. Pre-coat is preferably applied from aqueous dispersion and has sufficient levelling agent content to keep it from separating into droplets when applied on a heavily waxed surface. Fluorinated surfactants, by themselves or mixed with silicon...

A protective glove comprising a glove body provided on its back side surface and on each finger portion with a ridge form of pad of a soft material such as rubber or the like extending from near the tip of the finger portion to the back main portion, the pad being formed on its upper surface with a central longitudinal groove and sewed, by machine sewing or the like, at the interior of the groove, to the glove body.

Vaccines affording protection against the diseases resulting from infection of cats with feline leukemia virus are produced from cells infected with that virus or from the virus alone.

A method of defense for use by a human defender against attack by an assailant comprising the steps of puncturing the skin of the assailant, and injecting a sublethal dose of an initially liquid chemical pain producing substance into the body of the assailant so as to cause him to break off the attack.
