Patent ES-401920-A1 (ES)
Title: Circular knitting machine needle selecting apparatus
IPC: D04B15/78
Filed: 1972-04-19
Abstract: Broadly, there is disclosed an improved apparatus and method for selecting controllably certain discrete bodies one from the other as the bodies move past a site of selection. More specifically, there is disclosed method and apparatus for selecting which of the needles carried within the tricks of the needle cylinders of rotary knitting machines are caused to knit or not to knit. In the device described, selection of the needles actually results, in the preferred arrangement, from the operation of magnet means including permanent and electromagnets upon edge portions of patterning or needle jacks located beneath the needles themselves, rather than by direct action upon the needles. The actuating or selecting mechanism generally comprises a first or lower magnet means that includes a pair of poles, one of which is shaped in such a fashion as to provide a cam surface against which one end (in this case, the lower end) of the jacks will be cammed into a preselected position. This preselected position is one in which the other ends of the jacks, here the upper ends, are moved into a select position where they can be magnetically engaged by a second or upper magnet means. The second magnet means includes a plurality of electromagnets, which in operation are sequentially energized, and permanent magnet means that serve to maintain the needle jacks in position for selection to the non-operative position and to maintain the jacks in the non-operative (non-knitting) position for a length of time sufficient to permit the jacks to clear the knitting cams located circumferentially about the periphery of the needle cylinder.

Patent ES-460795-A1 (ES)
Title: Method of an apparatus for extracting, measuring and adding a product
IPC: B29C48/29
Filed: 1977-07-15
Abstract: To extract and measure out a product from a bulk stock and adding said product inside a hopper use is made of at least three perforated surfaces or plates superimposed on one another and in contact with one another so that the product to be extracted is trapped in the hole(s) in the center plate between the top plate and the bottom plate by a relative movement of the top plate in relation to the two other plates then stationary in relation to each other and the product so trapped in the hole(s) in the center plate is extracted to the outside by a relative movement of the center plate in relation to the top plate and the bottom plate, then stationary in relation to each other, or by a relative movement of the bottom plate in relation to the center plate and the top plate. The addition and mixing of the additive so extracted with a product contained in a hopper, which products may be a pigment and a plastic in granules in a hopper, is effected by making a cavity in the bulk of the product contained in the hopper in an area close to its delivery nozzle and by pouring through the bulk of said product, from one or several distributors controlled by the device fed by the hopper, the additive(s) into the cavity for mixing there, which avoids dirtying the whole of the hopper and makes better and more proportionally accurate mixing possible. The invention is particularly useful when small grain or powdered products have to be measured, as is particularly the case in the plastics processing industry.
