Patent ES-429324-A1 (ES)
Title: Ceramic capacitors
IPC: B32B7/00
Filed: 1974-08-16
Abstract: A sintered ceramic article which comprises internal electrodes and/or conductors is formed by producing a sintered ceramic body that has areas of ceramic with interconnected pores extending to an outer face thereof and providing a conductor in said porous areas. The ceramic body may be formed by depositing, as by screen printing, on sheets of a powdered dielectric or insulating ceramic material bonded with a temporary bond, an area of a temporarily bonded powdered ceramic material which on firing becomes porous, consolidating a plurality of such sheets, and sintering them. Subsequently a conductive material may be provided in the porous areas by impregnating said areas with a conductive material or with a material which is reacted or decomposed to form a conductive material in said areas.

Title: Loading of fuel rods
IPC: G21C21/08
Filed: 1974-12-31
Abstract: A method of loading fuel rods of the nuclear variety with radioactive pellets wherein the rod is evacuated, subsequently filled with an inert gaseous atmosphere, loaded with such pellets in linear array, and sealed. The pellets in this method are brought in linear array from a supply station to a predetermined situs and then are transferred in such array into a linear bed which is subsequently sealed, evacuated of atmosphere and then filled with helium. The pellets are then transferred in such linear array from the bed to a communicating fuel rod and the latter is sealed in form for use in the core of a nuclear reactor.
Patent ES-443181-A1 (ES)
Title: Supersonic shock wave compressor diffuser with circular arc channels
IPC: F04D29/44
Filed: 1975-12-03
Abstract: A supersonic shock wave compressor diffuser forms a concentric annulus about a radial compressor having a central axis. Circular channels diverge with an increasing divergence angle as they extend along an arcuate longitudinal center line from an inner circumference very near the periphery of the compressor to the outer circumference of the diffuser. Shock waves may occur within the channels near the inner circumference of the diffuser or may occur within a vaneless diffusion space adjacent the periphery of the compressor and provide efficient energy conversion and reduce the velocity substantially below MACH 1 to further improve the efficiency of the subsonic diffusion downstream therefrom. A logarithmic spiral is approximated by a circular arc subtended by the channel longitudinal axes to permit recovery of angular momentum while the circular cross section of the channels permits recovery of swirl velocity energy. The required diameter of the outer circumference of the diffuser is reduced by using the shock waves to greatly reduce gas velocity within a short distance, by the curvature of the channels and by the angle of incidence of the longitudinal channel axes.
Patent ES-444282-A1 (ES)
Title: Fluorescent lamp with envelope grooves
IPC: C03B23/051
Filed: 1976-01-05
Abstract: A low pressure discharge lamp, particularly a fluorescent lamp, having a plurality of separate and continuous grooves along its length each of which is formed for 360 DEG around the envelope. The groove configuration maintains a generally arcuate cross-section of varying radius to thereby alter the wall recombination rate of the plasma ions with the phosphor. In the embodiments where the cross-section of the envelope as deformed by the groove is non-circular, the invention also acts to increase the plasma arc stream length thereby changing the electrical and luminous properties of the lamp. A method and apparatus for making the grooves using a plurality of heat sources is also described.

Title: Bushing for leaf valve - has oblique threaded stub and contoured seat for hand operated fluid valve
IPC: F16K41/12
Filed: 1976-09-10
Abstract: The leaf valve or diaphragm valve is fixed into a bushing, and has a valve seat (18) obliquely between inlet (14) and outlet (16). The valve cap (24) is screwed (22) into the valve housing (12) and sealed by an extra welded seam (26) to prevent fluid leaking out.

Patent ES-461687-A1 (ES)
Title: Polyvinyl alcohol compositions for use in the preparation of water-soluble films
IPC: C11D17/04
Filed: 1977-08-17
Abstract: Compositions consisting essentially of a (i) resin mixture containing a low molecular weight polyvinyl alcohol and a medium molecular weight polyvinyl alcohol, and optionally, a copolymer of vinyl alcohol and an ethylenically unsaturated ester and (ii) as a plasticizer a polyethylene glycol, which compositions can be used for preparing films by melt extrusion or aqueous casting.

Title: Method for preparing active anodes for electrochemical processes particularly for manufacture of hydrogen
IPC: C25F3/02
Filed: 1978-03-15
Abstract: Active anodes are produced which are used in electrochemical processes, in particular the electrolysis of water to produce hydrogen.

Abstract: The process involves polymerisation of the monomer at elevated temperature in a saturated hydrocarbon which is liquid under the process conditions and in which both the monomer and the polymer formed are soluble, by means of a chromium oxide supported catalyst which is obtained from a catalyst precursor (which is itself a silicon dioxide-based, finely particulate support which is homogeneously coated with a chromium compound) by (1) treating the catalyst precursor (if necessary with addition of a promoter) at elevated temperature with an oxygen-containing gas, and then (2) allowing carbon monoxide to act on the product obtained from step (1). The process is characterised in that the chromium oxide supported catalyst employed is prepared from the catalyst precursor by using, in both steps (1) and (2), the solid in the form of a fluidised bed which is maintained by a carrier gas stream, with the provisos that (1) in step (1) the oxygen treatment is carried out at a temperature of from 400 to 1500 DEG C for a time of at least 30 minutes, and (2) in step (2) the carbon monoxide treatment is carried out at a temperature of from 250 to 500 DEG C for a time of from 0.5 to 3 hours by means of anhydrous and oxygen-free gas which comprises nitrogen to which a total of from 100 to 1000 mol%, based on the chromium trioxide content of the product obtained from step (1), of carbon monoxide is added, distributed evenly over the total carbon monoxide treatment time.

A removable protective paper (38) is arranged over the adhesive material. The lower layer (16) of loose fibrous material is provided with recesses (18) which serve to take up fairly large, abruptly occurring quantities of liquid. The sanitary towel is capable of absorbing large, abruptly occurring amounts of liquid, so that leakage is prevented.

Abstract: A method of and apparatus for making up two members (14, 16) having mated threaded connections such as tubing and casing used in drilling and production of oil wells, for ensuring that sufficient threads have been engaged, and proper torque has been applied thereby producing a leak proof joint. The mating threaded connections are threadably engaged while measurements are made of the torque (64) required to turn one of the members relative to the other, and measurements are made of the number of turns (152) of the members relative to each other. Simultaneously, the measured torque and measured turns are plotted on an x-y graphic display (151) showing the torque/turns relationship. The graphic display also includes prerecorded values of minimum and maximum turns, and reference, minimum and maximum torque for the particular threaded connection. The method and apparatus shows, during makeup, any abnormal, torque/turns relationship that may indicate a defective makeup. The method and apparatus also reduces the speed of makeup when the measured torque reaches a predetermined value for controlling the end point of the makeup. A portion (40) of the apparatus may be used independently as a torque measurement assembly.

Title: Apparatus and process for medium consistency oxygen delignification of pulp.
IPC: D21C9/10
Filed: 1980-12-02
Abstract: Medium consistency oxygen delignification of pulp is carried out in a series of tubular reaction zones. Rapid delignification is achieved by agitating the pulp by rotating a timing screw in the first reaction zone at a speed in excess of 10 rpm, modifying the flights on the timing screw to increase the amount of agitation, or a combination of the two. Primary oxygenation is carried out in the first reaction zone while subsequent zones provide the retention time needed for the delignification reaction to go to completion. A thick stock pump is used to introduce the pulp into the first reaction zone.
