Patent ES-372184-A1 (ES)
Title: Metering devices
IPC: A01C7/12
Filed: 1969-10-03
Abstract: A seed or fertilizer metering device comprises a body 22 and a rotary metering member 15 having a fluted portion 45 and a tubular extension 46 non-rotatably mounted on a drive shaft 19, and a cylindrical cut-off element 48 freely rotatably mounted on the extension 46, the shaft 19 being axially movable by means of a handle 71 so as to bring the metering member 15 into an in-use or an out-of-use position, from which latter position the member may be withdrawn from the body in a direction transverse to the said axis. The device is mounted beneath an aperture 18 in a storage hopper. The fluted portion 45 rotating with the shaft 19 meters quantities of material to a seed boot 43 hung on the hooks 41. A locking ring 51 prevents the extension 46 and the cut-off element 48 from moving axially with respect to the shaft 19. A sealing disc 56 axially movable relative to the shaft 19 and fluted portion 45 is rotatably journalled in an aperture 26 in the body 22, a U shaped spring 60 holding the disc in position. When the member 15 is to be moved to the out-ofuse position the lever 71 is operated to move the shaft 19 from right to left (as seen in Figs. 2 and 4). The locking ring 51 and hence the cut-off-element 48 are thus moved to the left, the latter replacing the part of or the whole of the fluted portion 45 which is in the chamber 69. The member 15 may be removed from the body by detaching the spring 60 from the bearing surfaces 65 and extracting the member 15 so that the cylindrical portion 48 passes through the open slot 28 and the shaft 19 through the slot 29. A cut off flap 68 is provided having a cross member 95 supported between the depending side walls 94, A spring control plate 98 is mounted on a shaft 20 and has a spring locator 101 and an abutment face 104 which engages the surface 103 on the flap 68. The flap is adjusted by rotating the shaft 20 and is able, because of the spring 100, to adjust itself in response to the amount or size of material being discharged by the fluted member 45. In an embodiment, Fig. 5 (not shown), a replacement fluted portion having smaller flutes is described.

Patent ES-415851-A1 (ES)
Title: Actuating apparatus for a diverter for sheet articles
IPC: B07C3/06
Filed: 1973-06-13
Abstract: In an actuating apparatus for a diverter for sheet articles fed at equal time intervals along a first path, the diverter being disposed at a fork junction where selected articles are to be diverted out of the first path into a second path, actuating linkage is provided for causing the diverter to effect diversion of the articles to the said second path in response to a signal. Control means disposed upstream of the fork junction are effective to deliver the signal when there is some irregularity appertaining to one of the articles or after a predetermined number of articles has passed. An energy store biases the actuating linkage towards a position in which diversion is effected but locking means hold the acutating linkage against the bias of the energy store. The locking means are at least indirectly coupled to a shaft that is rotated so that the locking means become ineffective at least once during each time interval. The locking means comprise a double-acting abutment insertable into the oscillatory path of a lever which is connected to the diverter, is movable therewith when the diverter is actuated and is provided with appropriate counter-abutment surfaces. Means are provided for charging the energy store during a fraction of one time interval in response to the signal and for keeping it charged during a predetermined period, a second energy store being provided which seeks to return the diverter after it has been actuated.

Patent ES-463628-A1 (ES)
Title: Feeder conduits for a glass furnace with heating electrodes
IPC: C03B7/098
Filed: 1977-10-28
Abstract: A feeder conduit is disclosed for conveying molten glass from a forehearth of a glass furnace to a glass forming machine. The feeder conduit includes an elongated conduit which receives molten glass from the forehearth and delivers the molten glass to an inlet of a bowl-shaped container. The container has an orifice in its bottom for withdrawing the molten glass therefrom and a vertical cylinder disposed within the container and above the orifice. The cylinder and side wall of the container opposite the inlet of the container define a semi-annular channel therebetween and a first electrode is inserted in the molten glass upstream of said cylinder and a second electrode is inserted in the molten glass within the semi-annular channel. The first and second electrodes are offset from the centerline of the feeder conduit. As the molten glass flows through the inlet in the container, around the cylinder and through the semi-annular channel, an electric current passes between the electrodes to heat the molten glass.
Patent ES-464921-A1 (ES)
Title: Hydraulic stirrer immersed below surface of a hot liq. - for churning liq. to mix in dust shaken from the dust separator
IPC: B01F15/00
Filed: 1977-12-09
Abstract: The base of a dust separator comprises a vessel filled with a hot liq. that is normally viscous at ambient temps., e.g. black liquor from producing wood pulp by digestion. Rising vertically through the bottom of the vessel is a supply pipe that is closed at its upper end. This vertical pipe has lateral orifices and on it is mounted, so that it can pivot, a hydraulic stirrer immersed below the surface of the liq. Hot liq. passes from the vertical pipe, through the orifices and out through the arms of the stirrer. The resulting rotation churns the surface of the liq. Used for removing dust shaken from dust collectors, e.g. electrostatic precipitators. The churning of the liq. surface wets all the dust and uniformly mixes it in the body of the liq. Prevents blocking of liq. outlets and adherence of the dust to walls. Requires no external power source to support the motion.

Patent ES-466990-A1 (ES)
Title: Anti-cavitation valve
IPC: F16K47/08
Filed: 1978-02-15
Abstract: The disclosure relates to a controllable valve structure, for throttling liquids under high pressure in a manner to minimize cavitation damage to the valve parts. The valve structure includes a cylindrical trim cage surrounding the valve seat and plug and formed with a relatively large multiplicity of passages for the radially inward flow of liquid. The orifices are so shaped and contoured that the effective throttling orifice of each is formed as close as practicable to the inner wall of the trim cage, causing formation of vena contracta in regions spaced as far as practicable from the walls of the trim cage. This reduces damage resulting from cavitation and correspondingly increases the useful operating life of the valve. In conjuction with the foregoing, the end face of the valve plug is recessed in the areas circumscribed by the annular valve seat, such that the inwardly displaced vena contracta are also displaced axially relative to the end face of the valve plug, minimizing cavitation damage to the plug, as well as to the trim cage. A specific valve construction is also disclosed, which achieves the theoretical objectives mentioned above which is, at the same time, capable of practical, economical manufacture.
