Patent ES-354441-A1 (ES)
Title: Dampening system for rotary offset press
IPC: H01J35/24
Filed: 1968-05-21
Abstract: Dampening fluid, such as water, is transferred from trough 1 to a roller 18, and eventually to lithographic printing cylinder 37, by a roller 2, which has an hydrophilic surface and is wiped by a flexible-surfaced roller 7, which is held so that it does not rotate after being contacted by the wetted surface of the roller 2. The roller 2 may have a chromium surface and the roller 7 one of rubber, and the roller 7 may be friction-braked, and be rotated by the roller 2 only until dampening fluid lubricates their contact so that the roller 2 slips against it. The roller 2 may be wiped to a greater or lesser degree by the roller 7 by adjustment of the pressure with which the roller 7 is urged against it. The roller 18, which is flexible-surfaced, may revolve at a constant speed and slip against the roller 2, so that the quantity of water delivered to it can be varied by changing the speed of the roller 2. Alternatively the roller 18 may revolve at a varying speed and drive the roller 2 by contact, slipping only when its speed falls so low that a constant-speed drive operating through a free-wheel device or an electrical equivalent of one takes over to drive the roller 2. The roller 2 may deliver dampening fluid to an inking roller, or to a train of inking rollers 28, 29, 31-36, 38, 39, 41-44, receiving ink from a duct roller 26 and messenger roller 27 and supplying it to a printing cylinder 37. The rollers 33, 34 and 39 of the train are reciprocated axially. The printing cylinder 37 may be replaced by one of a different size and the inking rollers 36 and 44 be moved relative to the rollers 33 and 43 to accommodate it.

Patent ES-431377-A1 (ES)
Title: Finishing apparatus
IPC: B24B31/073
Filed: 1974-10-25
Abstract: A machine for finishing parts, having part-isolating means such as vertical partitions or dividers, defining one or more compartments, disposed at least partially within the finishing chamber, each compartment designed to accept a part or parts to be finished and to maintain parts isolated from other parts. The finishing chamber and the part-isolating means are movable with respect to each other. As a result, as the part moves along the finishing chamber during the course of the finishing process, the compartment defined by the part-isolating means, e.g., partitions, moves longitudinally with the part and isolates it from other parts. In one embodiment of the invention, the part-isolating means, such as partitions for defining compartments for the parts, also moves vertically or pivotally with respect to the finishing chamber, e.g., to clear rises therein. Thus, in effect, the compartment surrounding the part and isolating it from other parts, moves with the part. In all embodiments the partitions are arranged to move longitudinally with the parts, and means are provided for retarding or stopping the parts longitudinally. Means is provided for separating finishing material from the parts and discharging finished parts. The finishing machines may be curvilinear or annular gyratory motion-type machines, linear tub-type machines, or any of various types of tumbling machines.

Patent ES-461489-A1 (ES)
Title: Power plant speed channel selection system
IPC: G05D13/62
Filed: 1977-08-09
Abstract: A turbine control system incorporating a speed monitoring system for generating an actual turbine speed measurement for control of turbine speed and load is disclosed. The speed monitoring system employs two identical speed channels each of both analog and digital form and a third channel of only analog form. The two identical speed channels of digital form and the third channel of analog form are coupled to a programmed digital computer based process controller for use in controlling turbine speed and load. The two identical speed channels of analog form and the third channel are coupled to an overspeed protection controller for use in preventing turbine overspeed. Within each controller, an identical channel is selected without preference to be used as the actual turbine speed measurement. A transfer between identical speed channels will only be performed if a malfunction is detected in that identical channel utilized as the actual turbine speed measurement. This transfer will be performed without affecting the operation of the turbine as controlled by either of the two controllers. The malfunction of any two of the input channel forms to a respective controller disables only the speed control function of that controller.
