Title: Thermionic electron-emissive electrode with a gas-binding material
IPC: H01J29/94
Filed: 1969-04-02
Abstract: A thermionic electrode comprises a metal sheet support having on one surface an electronemissive coating and on the other surface a coating of a getter material which diffuses through the support and has an activating influence on the electron-emissive coating. The sheet metal support may be of Mo, Ni-plated Fe, Ni or "cathode-Ni" (i.e. Ni with a small amount of Mg, Al, Si or Zr) and between 20 and 100 Ám thick. The getter material, which is of the high temperature type since it is heated together with the emissive material, may be Zr, Ti, La, Ce or Th and may contain 20-60% by weight of W and/or Ni powder. In coating the support with getter material, metal particles, e.g. of V, Mo, Fe, Co or, preferably, Ni, are first sintered on to the support surface and the getter material, generally in the form of hydrides, is provided in the interstices between the metal particles and the coating thus formed compressed between rollers to trap the getter. The coating of emissive material on the other face of the support may be provided in a similar manner, and may comprise Ba, Ca and Sr carbonates with 1-10% by weight of Ti, Zr, Hf or Th, having a density of between 1 mg. and 10 mg. per square centimetre of emitting surface. The electrode is activated by heating. In an example the support strip is "cathode-Ni" containing 0À03-0À09% by weight of Mg, is 50 Ám thick and the coatings on each surface are 10 Ám thick, the getter being Zr with 30% by weight of Ni. The getter material is also an activator for the emissive coating, e.g., the getter may include Zr which diffuses through the support to reduce, for instance, BaO to free Ba. The electrode may be used in a diode or triode, Figs. 1 and 5 (not shown) and may comprise a cylindrical support with the emissive layer on the outside and the getter layer on the inside surface and housing a heater. Alternatively, in a low pressure Hg vapour lamp for example, Figs. 2 and 7 (not shown), the emissive layer is on the inside and the getter on the outside of a cylindrical support. Furthermore the electrode may be used in an electron gun of cathode ray tube. Electrode dimensions are given in a number of examples. In manufacturing a support, Ni particles may be magnetically aligned prior to sintering.

Patent ES-418109-A1 (ES)
Title: Flow controller for flowing products, more particularly, bulk materials
IPC: G01G11/00
Filed: 1973-08-22
Abstract: The flow controller has a closure member of adjustable through-flow cross-section arranged on a storage bin or a gravity discharge pipe, and a regulating drive for regulating the through-flow cross-section. An inclined impact plate is secured on a first lever arm of a balance beam, in downwardly spaced relation to the closure member, so that the impact force on the plate, due to deflection thereby of the product falling through a given distance, is proportional to the actual value of the flow rate as expressed as quantity by weight per unit of time. The balance beam is pivotally connected intermediate its ends to a fixed frame and has at least one counter weight on a second lever arm, and an ajustable force-producing device acts on the balance beam in opposition to the impact force to regulate the through-flow cross-section. The deviation between the desired and actual values of the flow rate of the product, resulting from the interaction between the impact force and the force-producing device, is converted into a corresponding positive or negative pressure signal serving as a regulating signal for the regulating drive. An auxiliary beam is pivotally connected separately to the fixed frame, and the adjustable force-producing device loads the auxiliary beam. A supporting edge is mounted on the auxiliary beam for adjustment longitudinally thereof in engagement with the second lever arm of the balance beam to transmit to the latter a precisely balanced proportion of the load produced by the adjustable force-producing means, indicative of the desired value of flow rate of the product, and acting in opposition to the impact force. The adjustable force-producing device may comprise a weight movable longitudinally of the auxiliary beam in cooperation with a percentage scale, or a pressure responsive diaphragm element acting on the auxiliary beam through a lever arm extending therefrom, and the diaphragm element may be adjustable longitudinally of the auxiliary beam. Several such flow controllers may be individually adjustable with respect to different products and controlled from a central station.
Patent ES-420387-A1 (ES)
Title: Table feeder
IPC: B07B1/28
Filed: 1973-11-08
Abstract: An improved table feeder type material handling apparatus includes a support table or tray which is moved through forward and return strokes by a dirve assembly to convey ore or other material disposed on the tray in a forward direction relative to the tray. In accordance with a feature of the present invention, the stroke or distance through which the tray is moved can be varied while maintaining the stroke rate substantially constant. To provide this capability, the drive assembly includes a rotatable input member which is connected with the support tray by a linkage. A connection between the linkage and the input member is offset relative to the axis of rotation of the input member. Therefore, when the input member is rotated about its central axis, one end of the linkage is moved along a circular path. The stroke distance through which the support tray is moved is adjusted by varying the angular relationship between the central axis of the input member and the path of movement of the support tray to thereby move diametrically opposite portions of the circular path relative to the path of movement of the support tray. A screening table or tray receives material from the support tray. The screening tray moves through forward and return strokes with the support tray. In addition, the drive assembly is effective to move the screening tray through up and down strokes to promote the movement of small particles of ore through openings in the screening tray.

Patent ES-436096-A1 (ES)
Title: Rolling mill gauge control
IPC: B21B37/18
Filed: 1975-03-26
Abstract: A rolling mill gauge control system and method are disclosed for controlling the delivery thickness or gauge of a strip workpiece leaving one or more roll stands of a tandem rolling mill. The initial roll opening setting and the initial speed setting for each roll stand are typically provided by an operator or a schedule calculation computer system prior to the passage of the work strip through the roll stand. Assuming these initial speed settings are correct, the known mass flow operational condition of the work strip in relation to the last stand target delivery gauge is used to establish the initial desired mass flow delivery gauge from each controlled roll stand of the rolling mill in relation to the desired delivery gauge from the last roll stand. Then as the work strip passes through each successive roll stand, and before the work strip reaches the X-ray gauge measurement device following the last roll stand, the roll force determined actual delivery gauge from each roll stand is compared with the initial desired mass flow delivery gauge to determine a work strip gauge error leaving the latter roll stand, which gauge error is utilized for determining a desired correction in the roll opening setting for that roll stand before the work strip reaches the X-ray gauge device.

Title: Picture display device and deflection coil both having self-aligning surfaces
IPC: H01J29/86
Filed: 1975-04-30
Abstract: In a picture display tubes having deflection angles of 110 DEG and more the conical central part near the transition to the neck has a substantially flat variation perpendicular to the tube axis. As a result of this an accurate positioning of the deflection device on the display tube is seriously hampered. This problem is solved by centering members which are present on the conical central part and which cooperate in a self-centering manner with centering members forming part of the supporting cage of the deflection device. The position of the deflection device in the axial direction is accurately fixed by abutment members forming part of the supporting cage in co-operation with abutment surfaces forming part of the envelope of the tube.
