Patent ES-483783-A1 (ES)
Title: Brake applying device.
IPC: F16D51/00
Filed: 1979-08-31
Abstract: A brake applying device for an internal cylinder having pistons operated to apply the brakes by one or both of hydraulic pressure or a wedge assembly that move transversely of the wheel cylinder. The wedge assembly has a wedge and rollers which act between the wedge and the pistons to facilitate movement of the wedge. The rollers are housed in a cage that can move relative to the wedge, the unloaded datum position of the cage on the wedge is determined by two opposed springs that act on the cage. In order to prevent the cage from becoming damaged during exceptional service conditions it has been arranged for the cage to move relative to the wedge during the initial application of the brakes. This is achieved by providing an abutment which is encountered by the cage during retraction of the wedge so as to compress one of said springs.

Filed: 1979-11-02
Abstract: This disclosure is concerned with a process of and apparatus for producing relatively low energy electron beams through pulsed cold-cathode beam generation in a mode of operation involving an important intermediate region of a substantially linear depth-dose profile characteristic that reduces the sensitivity to possible voltage variations, and with improved triggering structures that significantly improve reliability and minimize erractic pulse generation and missing pulses, thus particularly adapting the process and apparatus for such stringent applications as production-line sterilization of surfaces, materials or workpieces passed by the apparatus.
Patent ES-485744-A1 (ES)
Title: Disc Brakes
IPC: F16D65/54
Filed: 1979-11-06
Abstract: The pads (4) of a disc brake assembly are held symmetrically relative to guide surfaces (14) of a carrier by springs (9) which clip over the backing plate (5) of each pad (4). The springs (9) each comprise two arms (10) which depend from a bridge portion (11) and resiliently grip the backing plate The edges (13) of the arms are bent out of the plane of the arms (10) and frictionally engage the surfaces (14). During limited forward movement of the pad (4) towards the disc the frictional engagement holds the edge of the springs (9) in position and the springs resiliently deform. When the brakes are released the springs (9) relax, thus retracting the pads (4) clear of the disc. Forward movement beyond a predetermined amount causes the springs (9) to slip on the carrier so that the amount of retraction remains substantially constant. The springs (9) include a portion (12) which biases the pads (4) into contact with the carrier guide surfaces (3).
Patent ES-8104699-A1 (ES)

The oscillator (OS) is followed by a pulse shaper (JF) which generates with at least one edge of each rectangular signal (S1) a pulse (S2) which is short in comparison with the duration of the period of the rectangular signals (S1) and which is supplied to the signal loudspeaker (L) via an amplifier stage (T).
Patent ES-8106641-A1 (ES)
Title: Controlled regenerative D-C power supply
IPC: H02M7/162
Filed: 1980-09-11
Abstract: A-C energy, from an a-c power system, is converted by a phase- controlled SCR rectifier bridge, which is followed by a series-connected filter choke (21) and a shunt-connected filter capacitor (29), to d-c power for delivery via a d-c bus to a load, such as an inverter (24) and an a-c induction motor (32) driven by the inverter. When there is a decrease in load demand, for example when the motor speed is to be reduced, fast speed control is obtained by regenerating power back into the a-c power system from the load. Power flow through the d-c power supply is reversed by means of a switching network (22,25,41,42), interposed between the filter choke (21) and capacitor (29), having a pair of reverse SCR's for cross-coupling the positive and negative lines of the d-c bus. When the reverse SCR's are fired into conduction, the connections between the filter capacitor and the bridge's output terminals are effectively reversed, thereby facilitating power flow from the load to the a-c power system.
Patent ES-8202360-A1 (ES)
Title: Extracellular microbial lipoheteropolysaccharides and derivatives, their preparation and compositions containing them, and their uses.
IPC: C09K23/00
Filed: 1980-10-15
Abstract: Growth of Acinetobacter Sp. ATCC 31012 on various substrates and under varying conditions has been used to produce two classes of extracellular microbial protein-associated lipopolysaccharides (the "emulsans") which, on a weight-for-weight basis, are probably the most efficient emulsifiers discovered and which possess certain characteristics that permit these unique extracellular microbial lipopolysaccharides to be widely used in cleaning oil-contaminated vessels, oil spill management, and enhanced oil recovery by chemical flooding. These classes have been named alpha -emulsans and beta -emulsans, both of which have substantially the same polymer backbone but differ from each other in certain important structural aspects. Deproteinization of emulsans by hot phenol extraction produces the lipopolysaccharide components (the "apoemulsans") of each of such th emulsans, which components have been shown to be completely N-acylated and partially O-acylated heteropolysaccharides made up of a major amounts of D-galactosamine and an aminouronic acid, the O-lipoacyl portions of such apoemulsans containing varying percentages of fatty acid esters in which the fatty acids contain from about 10 to about 18 carbon atoms. Base hydrolysis under mild conditions of the emulsans and apoemulsans produces derivatives (the " psi -emulsans" and apo- psi -emulsans", respectively) which are completely N-acylated and partially to completely O-deacylated. Base hydrolysis under strong conditions of any of these products produces another derivate (the "proemulsans") which is completely O-deacylated and is partially H-deacylated. Emulsans and apoemulsans, both of which biopolymers are strongly anionic, exhibit a high degree of specificity in the emulsification of hydrocarbon substrates which contain both aliphatic and cyclic components. In addition, these extracellular microbial polysaccharides as well as their O-deacylated and N-deacylated derivatives are adsorbed on and capable of flocculating aluminosilicate ion-exchangers, such as kaolin and bentonite.
Patent ES-8106981-A1 (ES)
Title: Inlead and method of making a discharge lamp
IPC: H01J61/36
Filed: 1980-12-09
Abstract: The inlead for the electrode sealed into a quartz arc tube has a foil portion which is stiffened by reversely folded lateral edges. The folds overlap the tapering region of greater stiffness where the foil portion joins the end portions. In making a discharge lamp, the electrode-inlead assembly is self-centering as a result of making the overall width of the foil portion and its folded edges exceed slightly the internal diameter of the quartz tube or neck. The frictional engagement between the folded edges and the inside wall of the neck retains the assembly in place while the neck is heat-collapsed onto the foil to seal the electrode assembly in place.

Patent ES-8301541-A1 (ES)
Title: Error correctable data transmission method
IPC: H03M13/00
Filed: 1981-05-19
Abstract: An error correcting encoding and decoding system for transmission and reception of digital data is arranged for high error-correcting ability of both burst errors and random errors. In encoding apparatus a digital signal is processed as a plurality of word sequences. The words are interleaved into a different arranging order and are subjected to different relative amounts of delay. Then, first check words are generated to satisfy a parity detection matrix, such as a Reed-Solomon code matrix. After this, the resulting data words and first check words are again interleaved and are provided with respective different amounts of delay. Then, second check words are generated to satisfy a similar matrix. Finally, the first and second check words and the data words are interleaved prior to transmission. In complementary decoding apparatus, the cross-interleaved received signal is de-interleaved in a fashion complementary to the interleaving performed during transmission and the data words are delayed a complementary amount. The received data words are decoded by providing syndromes generated according to the parity detection matrix and burst or random errors are corrected by the check words.
