The metal oxide media includes oxides and hydroxides of iron, and other metals. The material is derived from basic-oxygen steel-making process, and includes a h igh calcium content. The oxide surfaces facilitate the adsorption of phosphorus, and the increased pH facilitates the precipitation of calcium and other phosphates. The oxides are a catalyst for converting organic phosphorus to inorganic f...

A method of improving security of a luggage wrapping system. Firstly, apply at least one band around a piece of luggage. Secondly, apply a polymer plastic wrap to the luggage.

L'invention concerne un circuit de multiplication numérique pour multiplier un signal numérique SN par une forme d'onde périodique, en principe sinusoïdale. Ce circuit utilise un générateur numérique (10) de phase périodique .PHI. variant en dent de scie, et il utilise une approximation des échantillons d'une fonction Ksin.PHI. par des sommes algébriques de puissances entières positives de deux po...

Trouser garment comprising an item of clothing that encloses the wearer's pelvis and has an opening (2) for the waist and at least one leg hole (3, 3'). A dividing line (9, 9') extends all the way between the waist opening and leg holes to separate one of two side pieces (7, 7') from a front or back piece (5). A hook and loop fastener band (11, 11') joined to an inside edge (10, 10') of the front ...

Securing a rigid or flexible filter (2) in a dimensionally stable frame (1) comprises stretching the filter and temporarily securing it in the frame using eg. a dot pattern (6a - 6c) or line of hot-melt glue, double-sided adhesive tape, etc. The frame is then at least partially surrounded by a preferably low permeability material (3), eg. needle-felt, that is subsequently secured in place by at le...
