Title: Multicavity klystron for microwave and uhf with interfering mode suppression slots in the ends of the drift tube
IPC: H01J25/12
Filed: 1967-12-22

Two slots at one end of the tube may be either diametrically opposite, or displaced through 90 degrees. The opposed ends of two drift tubes terminating in a common cavity may each have one or two slots, the slot pattern in one being displaced through 90 degrees with respect to that in the other.

Title: Telephone subset with resistive hybrid network
IPC: H04M1/58
Filed: 1968-05-09
Abstract: An anti-sidetone circuit for a telephone subset comprises a bridge circuit including oppositely directed amplifiers 57 and 58 in opposite arms with the two wire line 52 connected across one diagonal of the bridge at points 63 and 64 and with a differential amplifier 56 connected to receive the signal across the other diagonal and apply it to the receiver 51. The microphone 50 is connected via a phase splitter 55 to feed signals of opposite polarity to amplifiers 57 and 58, amplifier 57 being a grounded emitter amplifier, providing a further 180 degree phaseshift to the signal applied to point 61 of the bridge, and amplifier 58 being an emitter follower providing no further phase shift to the signal applied to point 62, so that signals of identical phase and similar amplitude appear across the differential amplifier from the microphone, providing only the required small sidetone, while appreciable signal is fed to the line 52. Amplifiers 57 and 58 present appreciable impedance to signals on the line 52 which are therefore applied, via capacitor 70 and capacitor 71 and relatively low value resistor 59, across the differential amplifier input, to be applied to the receiver 51.
Patent ES-357047-A1 (ES)
Title: Selective adsorption process
IPC: C01B3/56
Filed: 1968-08-08
Abstract: A four bed adiabatic pressure swing bed cyclic process for separating gas mixtures by adsorption comprises taking each of the four beds in turn and in the appropriate time relationship through the sequence of steps shown. Thus, feed is passed by manifold 10 to bed A where impurities are adsorbed and product effluent leaves by manifould 11. Adsorption is discontinued before impurity breakthrough occurs, whereupon feed is switched to bed D, and thereafter in turn to beds B and C before bed A comes on-stream again in the next cycle. After adsorption in bed A has been discontinued, the pressure of bed A is equalized with that of bed B (which is being repressurized prior to coming on-stream) through the discharge end of bed B. Thereafter, bed A is cocurrently depressurized by connecting its discharge end to the discharge end of bed C, thereby purging bed C prior to repressurization of residual sorbate through manifold 12. Bed A is then countercurrently depressurized through its inlet end to desorb and remove sorbate through manifold 12 and afterwards purged by introducing gas from the countercurrent depressurization step of bed D to its discharge end. Bed A is then repressurized partly with gas from the pressure equalization step of bed B, and partly by the recycling of a portion of the product effluent. As described, the process is of particular application to the removal of light hydrocarbons, carbon monoxide and dioxide, ammonia, hydrogen sulphide, argon, nitrogen and water from gas streams consisting principally of hydrogen, but is also of value in separating nitrogen or helium from minor amounts of impurities. A flow sheet is provided (see Fig. 1, not shown) setting out details of the various valves and interconnections necessary. In one example, the beds are each constituted of a first section of active carbon and a second section of calcium zeolite A. The process may also be adapted for use with five beds (see Fig. 3). Reference has been directed by the Comptroller to Specification 1,067,177 and 989,073.

Patent ES-406457-A1 (ES)
Title: Ball valves
IPC: F16K5/20
Filed: 1972-09-07
Abstract: A ball valve having a novel seat arrangement whereby the seat rings, placed on opposite sides of the ball closure member, are each retained by a ferrule which is screwed into the valve body. The ferrule secures and positions the seat ring in a manner whereby the seat is advanced toward the ball to simultaneously form a seal between a counterbore in the valve body and the outer periphery of the seat, and, to preload the seat against the surface of the ball closure member, forming a seal therebetween. Such simultaneous forming of seals is assisted by a tapered conical surface of contact between seat rings and their respective ferrule. Thus, the advancement of the ferrule toward the seat results in a seal being established simultaneously between the seat and the body, and, the ball closure member and seat.
Patent ES-418984-A1 (ES)
Title: Process for preparing high molecular weight polyisocyanates
IPC: C07C67/00
Filed: 1973-09-21
Abstract: There is disclosed an improvement in the process for producing high molecular weight polyisocyanates by the reaction of volatile diisocyanate and an active hydrogen-containing substance. The improvement consists in using, as solvent medium for the reaction between the volatile diisocyanate and hydrogen-containing substance, a solvent, in particular acetonitrile, which has a strong affinity for the high molecular weight polyisocyanate, is only partially miscible with the aliphatic and/or cycloaliphatic hydrocarbons used as solvents for the extraction of unreacted volatile isocyanate, has a low boiling point by virtue of which it is easily distillable without causing collateral reactions and, finally, may be replaced by the solvents which are normally used in applying the high molecular weight polyisocyanates in practice, such as ethyl acetate, butyl acetate, acetic acid esters in general, alkyl carbonates, ketones, chlorinated hydrocarbons, etc.
Patent ES-422283-A1 (ES)
Title: Apparatus for treating textile fabric to retard inflammability
IPC: D06B23/16
Filed: 1974-01-14
Abstract: Textile fabric previously impregnated with THPOH is treated to retard inflammability by passage therethrough of toxic ammonia gas in apparatus which permits the THPOH-NH3 reaction to be carried out in a sealed chamber preventing escape of the toxic gas. The invention operates to confine the gas in a flow path whereby substantially all of the gas flowing through the apparatus is passed directly through the fabric. The fabric is passed through the sealed chamber by means of gas-tight entrance and exit portals. A perforated drum is mounted within the chamber and the fabric is passed about the perimeter of the drum. Sealing elements cooperating with the drum confine ammonia gas introduced into the interior of the drum to flow only through those perforations covered by fabric. Undue accumulation of water which is a product of the reaction is avoided by both the slanted ceiling configuration of the chamber which promotes condensate runoff and the positive gas flow velocity established within the chamber which tends to draw water vapor from the reaction site.

Title: Pollution control system and method for the removal of sulfur oxides
IPC: C01B17/04
Filed: 1978-09-12
Abstract: A pollution control system and method in which sulfur oxides in flue gases are adsorbed by activated char in a gas-solid contacting device. The saturated char is regenerated in an integrated desorption-reduction vessel, to which crushed coal and combustion-supporting air are supplied. A portion of the crushed coal is burned to provide the heat for the regeneration of the char, resulting in the formation of sulfur dioxide and carbon dioxide gases, and the chemical consumption of a portion of the char. The remaining crushed coal reduces the sulfur dioxide to gaseous sulfur, and results in a material having a porous system suitable for use in the adsorption of sulfur oxides. The remaining regenerated char and the oxidized coal are cycled back to the gas-solid contacting device, and the gaseous sulfur is condensed to liquid in a condenser.
