Patent ES-497751-A0 (ES)
IPC: C22F1/00
Filed: 1980-12-15
Abstract: This invention is directed to an improved zinc containing metallic coated ferrous product, particularly sheet and strip, which is resistant to intergranular penetration by zinc and embrittlement of the ferrous base. Use of such zinc containing metallic coated ferrous product in elevated-temperature service, such as found with certain appliances and automotive exhaust components, is enhanced by the coated products of this invention. The resistance to embrittlement of the zinc containing metallic coated ferrous base, when subjected to elevated service temperatures, is achieved by the use of a high-phosphorus containing steel base. For a plain content steel base, a phosphorus content of at least 0.020% by weight, preferably at least 0.030%, and more preferably at least 0.039% was found sufficient to render such zinc-alloy coated ferrous base resistant to embrittlement by zinc. By use of such high phosphorus ferrous base, for the reception of a zinc containing alloy coating, an improved metallic coated ferrous product has been found which resists intergranular penetration by zinc and embrittlement of the ferrous base. Such coated product has extended service life at temperatures above about 450 DEG  F. (232 DEG  C.) and when restored to room temperature possesses a high degree of ductility.

Abstract: Apparatus for continuously producing an elongated strip-like fastener member is disclosed which facilitates highly efficient formation of the fastener member with a great multiplicity of resiliently flexible hook-like projections. The method comprises the formation of an extrusion of plastic material which is shaped between a pair of coacting first and second rollers of the apparatus. Notably, one of the rollers is formed of a series of plates and defines a plurality of hook-forming cavities about its periphery within which the hook projections of the fastener member are formed. The forming roller is suitably cooled so as to effect substantial reduction in the temperature of the molten plastic extrusion form which the fastener member is formed. In this manner, the fastener member may be removed or stripped from the forming roller without opening of the hook-forming cavities, thus promoting highly efficient formation of the fastener member without resort to unduly complex equipment or processes. The fastener is uniquely configured and includes upstanding hook-like engaging elements having stem portions of at least partially arcuate configuration to produce a combination of properties previously unknown in such fasteners.

Abstract: Described are new Saccharomyces cerevisiae yeast strains transformed withan  alpha -galactosidase gene (MEL<+>) using recombinant DNA methods. Baker's and distiller's yeasts producing  alpha -galactosidase are used in the corresponding industry because they are able to utilize the raffinose contained in molasses. This results in a greater yield of yeast (or ethanol) and in reduction or elimination of the costs associated with the biological oxygen demand (B.O.D.) in the effluent of factories. As a result of the improved ability of brewer's yeasts to produce  alpha -galactosidase a sensitive method for monitoring pasteurization of beer is provided. The new yeast strains prepared by using recombinant DNA methods produce more  alpha -galactosidase than naturally occurring alpha -galactosidase producing yeast strains. Also described are methods for marking yeast strains and for producing stable transformants of yeasts.

Abstract: Of two edges (14, 16) to be joined together of a multilayer foil, the inner edge (16) is obliquely trimmed in the longitudinal direction prior to the pressing together in such a way that the layer (6) located remote from the surfaces (10, 12) to be pressed together protrudes beyond the other layers. If the two layers (14, 16) are pressed together during the welding operation by means of two tool elements, not shown, then the inner layer (6) of the inner edge (16) overflows so as to form one uninterrupted layer with the inner layer (6) of the outer edge (14). When the foil is used as packaging material, in particular as a tubular liner for a packaging tube, it is assured that the product to be packaged will come into contact only with the inner layer (6), so that an undesirable reaction with one of the other layers is avoided.
