Patent ES-335096-A1 (ES)
Title: Method of making aluminum sheathed coaxial cable
IPC: H01B11/18
Filed: 1966-12-30
Abstract: A method of making coaxial cable comprises continually advancing a plastic foam insulated centre core conductor, progressively forming a sheath as a longitudinally seamed tube of larger inside diameter than the outer diameter of the core insulation, welding the seam, drawing down the sheath into contact with the core insulation, and pulling the cable continuously to keep the sheath and core advancing. The sheath 14 is formed around the core 10 in a forming die 16 and passes through a roll stand 30 to a welding station 32. A further roll stand 36 serves to damp any movement of the cable as it enters a sizing die 42 and holds it steady during welding. Lubricant is poured from a pipe 46 on to the sheath before it enters the die 42 and the cable 14a passes from the die to be wound helically over drums 52, 54, which are driven rotationally in a fixed frame 57. Alternatively the lubricant is cleared from the drawn cable 14a by a nozzle 74 and the cable is frictionally gripped between moving endless bands 66. The sheath is preferably of aluminium, but may be of copper.

Patent ES-424863-A1 (ES)
Title: Electronic hybrid amplifier
IPC: H04B3/36
Filed: 1974-04-08
Abstract: An improved bidirectional amplifier using the inversion of signals across the output of a transformer having a balanced load is disclosed. The signals for the desired direction are inverted relative to one another by the transformer and fed to the inputs of a difference amplifier. The signals are algebraically summed by the amplifier to comprise an output approximately double that of either input. Reflected signals for the unwanted direction are not balanced and thus are not inverted across the transformer. When these signals are fed to the difference amplifier they are cancelled within the amplifier since there is no difference between the signals.

Patent ES-448691-A1 (ES)
Title: Hot water floor heater
IPC: E04B5/48
Filed: 1976-06-09
Abstract: The heater is in the form of a hot water carrying pipe coil supported on a suitable base, such as a sub-floor, and having spaced parallel pipe ducts interconnected by pipe bends. A pair of parallel supporting laths, preferably in the form of flat bars, are fixed on the sub-floor in spaced relation to the opposite side walls of a room to be heated, and circularly curved members are secured to the laths at spacings therealong equal to the spacing between the pipe ducts, the curved members on one lath being staggered longitudinally relative to the curved members on the other lath. The connecting bends of the pipe coil are looped around these curved members, which latter thus serve as a pipe laying gauge. Stop members are secured to the laths in spaced relation to the free ends of the curved members to form, in effect, troughs for the connecting pipe bends. Heat transmitting metal lamellae are secured to the pipe ducts to interconnect adjacent pipe ducts, and these lamellae may be formed with half-shell portions at each end, one overlying a pipe duct and the other underlying the adjacent pipe duct. The lamellae may be formed with alternating rows of depressions and elevations. In hard to heat areas of the floor, the parallel pipe ducts may be arranged much closer together than in the remainder of the floor, as by having a pitch which is one half the pitch of the pipe ducts in the remainder of the floor and, in such case, the curved members in the hard to heat area of the floor have an angular extent of more than 180 DEG and a radius which is less from that of the curved members in the remainder of the floor. The lamellae may be metal or may be metal powder-containing plastic.

Patent ES-465327-A1 (ES)
Title: Distribution of gas under pressure
IPC: F17C9/02
Filed: 1977-12-22
Abstract: The present invention relates to a method of and a cryogenic installation for distributing gases. From a storage tank at low pressure, successive portions of cryogenic liquid are withdrawn to an enclosure, which is isolated by closing a valve. After this, a further valve is opened, the effect of which is to cause the pressure in a receptacle to rise to the high distribution pressure and to allow the gas concerned to condense to a certain degree so that said enclosure is filled with liquid under pressure. The liquid evaporates partially at the periphery and is thus transferred to a heater and from there to a buffer container. The invention is applicable in particular to the distribution of oxygen, nitrogen and argon under pressure.

Process is relatively economical and uses generally available basic techniques and materials. In an example, a coating of macroscopic field-oriented acicular crystals was produced on a Ni-plated steel substrate by plating with a soln. of 160 g/l NH4NO3 and 90 g/l AgNO3 for 20 mins. at 1.5V.
Patent ES-467254-A1 (ES)
Title: Furnace flue apparatus for improved fly ash separation
IPC: F23G5/46
Filed: 1978-02-23
Abstract: The disclosed apparatus is disposed in the "U"-section deflector at the bottom end of flues connected to each other in a multiple-flue, vertical flue furnace. A deflecting plate and two associated projections, one on the plate and the other on the wall, influence the flow of gases in such a manner that first the radius of curvature of the gas making the turn is decreased, and second the distribution of flow at the input cross-section of the flow-receiving flue is more uniform. The first effect improves the effectiveness of fly ash removal from the turning gas stream. The second effect prevents localized sooting and uneven heating of a heat exchanger which may be installed in the end of the receiving flue.
