Title: Magnetic control system for circular knitting machines
IPC: D04B15/78
Filed: 1976-04-26
Abstract: An improved magnetic pattern control system for circular knitting machines. Each system includes a bar forming a bearing surface. Selector elements of the knitting machine are adapted to be tipped or pivoted about the bar as they pass the bar to move corresponding knitting needles into a knitting or non-knitting position. The bar extends in the direction of travel of the selector elements. A plurality of electromagnets are mounted at each selection station of the circular knitting machine. Each electromagnet has a pair of polar surfaces. The midpoint between all pairs of polar surfaces coincide with respect to each other and these coinciding midpoints are therefore equidistant from the bar forming the bearing surface.

Patent ES-463460-A1 (ES)
Title: Apparatus for applying a label to an object
IPC: B65C3/00
Filed: 1977-10-21
Abstract: Apparatus for labeling objects including fruits supplied to a labeling station by an endless conveyor. Labels on a carrier tape are moved from a supply reel by a knurled roller which impresses a surface weakening pattern on each label so it will readily conform to a non-planar surface of the object. The tape is formed into a feed storage loop by an oscillatable tension regulating arm which controls actuation and deactuation of the knurled roller. An indexing tape segment passes through an indexing block in a transfer station, where each entering label is sensed by a detector. Indexing movement of the tape is initiated by an object detector on the conveyor. Indexing moves the tape around a sharp bend to strip the detected label from the tape and position it in a label holding frame. A label transfer wheel with peripheral suction cups is operated in timed relation to the detection of an object on the conveyor, to move a suction cup under the label in the holding frame, whereupon a vacuum is applied to grip the label and carry it to a position where it is pressed against a surface of the detected object, at which time the vacuum is released. A thin lip of the suction cup is deformed by the pressing action to vent the cup interior to atmosphere. A take-up storage loop is formed by a second oscillatable tension regulating arm which controls the intermittent actuation of a motor driven tape take-up reel.

Title: Process and apparatus for producing aqueous sodium chloride solutions from rock salt.
IPC: C01D3/08
Filed: 1981-02-27
Abstract: The invention relates to an open dissolving chamber for rock salt and to a process for the production, free from vapors, of concentrated, aqueous sodium chloride crude brine by continuously dissolving rock salt in this dissolving chamber. The dissolving chamber contains a heap of rock salt with which the brine which is unsaturated in respect of salt comes into contact. The brine thereby becomes saturated with sodium chloride and then passes out of the dissolving chamber. In the present process, the unsaturated brine enters at the base of the dissolving chamber. The saturated crude brine is removed from the rock salt through at least one vertical or inclined screen which largely holds back suspended rock salt particles. The liquid level of the saturated crude brine in the dissolving chamber should not reach the surface of the heap of rock salt, and the side of the screen facing the interior of the dissolving chamber should be completely covered with a mixture of saturated crude brine and rock salt.
