Patent ES-427095-A1 (ES)
Title: Method for refining iron-base metal
IPC: C21C5/36
Filed: 1974-06-07
Abstract: A method for refining iron-base metal such as pig iron which contains minor amounts of elements including silicon, manganese, phosphorus, carbon, sulfur, and other incidental impurities, characterized by the steps of containing molten iron-base metal in a metallurgical vessel, heating and oxidizing the molten metal to cause chemical reactions to remove excessive contents of the said elements, adding slag conditioners of relatively high basicity (lime-to-silica ratios of 2.5:1 to 4.0:1) which conditioners consist essentially of oxides of selected metals including iron, manganese, silicon, magnesium, and calcium, and which conditioners have a melting point of from about 2000 DEG to 2800 DEG F, and continuing to heat while oxidizing the mixture of the molten metal, slag conditioner, and slag-forming materials until said minor amounts of elements are reduced to the desired percentages, and are retained in the slag formed. More specifically, the function of the slag-conditioner is to eliminate the encapsulation of large particles of lime by dicalcium silicate and thereby more rapidly taking the lime into solution. Thus, the need for fluorspar is eliminated.

Title: Plant for continuous production of explosive containing explosive oil
IPC: C06B21/00
Filed: 1975-04-09
Abstract: An explosive is produced in a continuous process made up of three stages. The first stage is mixing the solid ingredients of the explosive and transporting it to a mixing station. The second stage is emulsifying nitroglycerine and transporting it to the mixing station where the nitroglycerine is separated from the water and combined with other liquid ingredients. The third stage is the mixing stage where the solid and liquid ingredients are mixed or kneaded and formed into suitably-sized explosive units. The mixing station is provided with a mixer having a pair of hoppers in which are deposited the liquid ingredients and the solid ingredients, and which empty into a housing having a pair of rotating mixing screws which mix the liquid and solid ingredients. The liquid ingredients never contact the bearings of the mixing screws. The ratio of liquid to solid ingredients of the explosive may be varied by varying the feeding rate of each.

Title: Method of preparing soluble collagen fibers
IPC: A23J1/10
Filed: 1980-11-18
Abstract: A method of forming soluble collagen fibers from raw animal hides is disclosed. Raw animal hides are treated with an aqueous solution of an alkali metal hydroxide and a dehydrating agent to remove the hair and fat therefrom to yield a substantially fat-free corium. The interfibular bonds of the collagen in the corium are stabilized with an aqueous solution of an alkali sulfate. The corium is neutralized and dissolved in an aqueous acid solution to yield a collagen solution. The pH of the aqueous collagen solution is adjusted to the isoelectric point of the collagen to precipitate the collagen fibers from the solution. The collagen fibers are dried. The collagen fibers so produced are useful in edible food, may be redissolved and further processed for a plurality of uses.

Title: Contact device.
IPC: H01H37/10
Filed: 1981-11-11
Abstract: A contact arrangement includes an elongated striker reciprocable in direction of its elongation and a pair of movable contacts moved by the striker and cooperating with adjacent stationary contacts so that during reciprocation of the striker between two end positions one of said movable contacts engages the stationary contact adjacent thereto while the other movable contact is spaced from the adjacent stationary contact, and vice versa. In order to obtain during the reciprocation of the striker up to the moment of switching the contacts a high contact pressure, the striker is provided with a guide extending transverse to its reciprocation direction for a movable guide body. The movable guide body is mounted on one end of a link member the other end of which is articulately engaged with an angle lever in the region of the knee of the latter. A tension spring is connected at one end to the movable guide body and at the other end to one arm of the angle lever, the other arm of which is pivotally mounted on said support. A stationary guide body is coordinated with the movable guide body and the arrangement is made in such a manner that during the switching movement the movable guide body first moves in one direction along one face of the stationary guide body and then in the opposite direction along an opposite face of the stationary guide body.
Patent ES-8301112-A1 (ES)
Title: Roll-up device for safety belts
IPC: B60R22/34
Filed: 1981-12-29
Abstract: A roll-up device, particularly for safety belts used in vehicles. The device provides a so-called automatic belt blocker with belt-sensitive and/or vehicle-sensitive blocking of the belt winding spindle, which is provided with a projection which cooperates with a locking member, which in turn can be locked in place via detents which engage with notches associated with a housing. There is the problem that, in the event of high belt forces, the locking member will slip away from the projection, and thus from the notches of the housing, thereby freeing the blockage. The aim of the invention is therefore to prevent the locking member from breaking out of its predetermined position in this way. To solve this problem, at least one overlapping arrangement is provided between the projection of the belt winding spindle, and the radially deflectable locking member, to ensure that the locking member does not move out of its position in the axial direction of the belt winding spindle during blocking. The overlapping arrangement preferably includes an opening in the projection, and protrusions on the locking member, which protrusions engage in the opening. The entire locking member may also pass through the opening. The invention has the advantage of locking the locking member in position not only radially, but also axially.
