Patent ES-364295-A1 (ES)
Title: Method of making electrode
IPC: H01M12/06
Filed: 1969-03-01
Abstract: An electrode is prepared by coating a face of a polymer membrane with an electrocatalyst, placing a metal grid on the coated face, placing the uncoated face on a resilient mat, and applying pressure to the grid. Suitable films are preferably unsintered and made of PTFE, polychlorotrifluoroethylene (PCTFE ),polyvinyl fluoride (PVF) or polyvinylidene fluoride (PVDF), of 0À5-20 mils. thickness. Suitable electrocatalysts include Nb, Co, Ni, Fe, Au, Cu, Pd, Ir, Pt, Rh, Ru, Os, Er, Ag and Ag or Au amalgams, which may be mixed with hydrophobic particles e.g. of PTFE, PCTFE, polytrifluorethylene or silicone rubbers. The metal grid may be of Ni, Cu, Fe, Ti, Ta, Ag, Au and alloys thereof, of 35-90% porosity and 1-20 mils. thickness. In an example an unsintered PTFE film is coated with an aqueous dispersion of Pt black and PTFE in 10: 3 weight ratio, an Ni grid is pressed into it as above, at 800 p.s.i., and the film is dried, cut to size, and mounted in a frame as an envelope cathode in a zinc/air cell using aqueous KOH electrolyte. Hydrophilic films, e.g. polymethyl methacrylate, polyvinyl alcohol, regenerated cellulose, or copolymers of vinyl chloride or vinyl alcohol may also be used.

Title: Apparatus and process for the continuous manufacture of a waveguide formed by a cylindrical helix
IPC: H01P11/00
Filed: 1973-03-13
Abstract: Apparatus and process for the continuous manufacture of a waveguide having a helically wound conductor with an exterior sheath extruded thereover in which a forming machine which can produce only a limited length of helix is stopped intermittently for the replacement of the conductor storage reels thereof but the extrusion press operates continuously. During the time that both the forming machine and the press are operating normally, they are maintained a substantially fixed distance apart, but during the time the forming machine is stopped, the extrusion press is moved toward the forming machine at a rate permitting uniform extrusion of the sheath on the previously formed helix. After the forming machine is restarted its forming speed is increased as the press is moved away therefrom until it reaches substantially its original spacing from the forming machine at which time the forming speed is returned to normal.

Title: Steam generator with split flow preheater
IPC: F22B1/02
Filed: 1973-07-23

Title: Method and apparatus for signaling brake lining wear of a brake
IPC: F16D66/02
Filed: 1974-06-05
Abstract: The method of the present invention is particularly characterized by the event of periodically changing the contact pressure between the friction shoe and the braking body at the mutual contact of the raised area and the counter area whereby, during the periodic changing of the contact pressure, a signal is generated to thereby indicate critical wear of the lining. Periodic changing of the contact pressure is indicated, via the control mechanism to the individual operating of the brake. As a further step in the method of the present invention there is provided periodic changing of the braking couple. The signal which is generated during the periodic changing of the braking couple may be in the form of pulsations of the vehicle deceleration. The raised area may be constructed in the form of a cam having a parabolically cured abutting surface. In addition, the counter area may be provided with a covering layer having a wearability which is of a lower order of magnitude of that of the material of the raised area but which is of a higher order of magnitude than that of the friction material of the brake lining.

Patent ES-478790-A1 (ES)
Title: Tubular scaffolding coupling.
IPC: E04G7/02
Filed: 1979-03-06
Abstract: A coupling for tubular scaffolding including a boss mounted on a standard by a pin or by welding and a wedge ring rotatably encircling and co-planar with the boss. Radial insets in the boss combine with the ring to form apertures in which pegs are located, the pegs being attached to the ends of ledgers and transoms. The inner face of the wedge ring has sloping wedge surfaces in the vicinity of the apertures which alter the radial dimension of the apertures. Thus, when a peg is located in an aperture the wedge ring can be rotated to wedge the peg firmly in the aperture. The problem existing prior to the invention was the difficulty of securing ledgers and transoms. This has to be done by screw couplings or by getting above the coupling in order to tighten it. The coupling of the invention can be operated from below, i.e. by a person standing on erected scaffolding.

Title: Process and apparatus for drying and preheating of coking coal in a single flight stream tube
IPC: C10B57/10
Filed: 1979-09-10
Abstract: A process and an apparatus for the drying and preheating of coking coal is described, in which a coarser grain fraction of the starting coal is separated out at least at one location in a flight stream tube through which the coal and a heat carrier gas are fed, and in which this larger grain fraction is subsequently reintroduced into the main stream containing only the finer grain fraction of the coal and the predominant portion of the heat carrier gas. The method and the apparatus through which the method may be carried out allow for a single-step process for both drying and preheating of the coal, make it possible to substantially reduce the length of the flight stream tube necessary, and increase the uniformity of the degree of pretreatment of the variously-sized fractions of the starting material.
