Patent ES-346345-A1 (ES)
Title: Adjusting device for disk brake
IPC: F16D65/56
Filed: 1967-10-23
Abstract: In or for a disc brake, a return spring 12 normally displaces a hollow piston 3 against a stop 10 on a pin 1 screwed into a caliper half 14. A further pin 17 projecting from pin 1 is resiliently biased against an inclined surface 16 of a sleeve 19 so as to provide automatic slack adjustment. As described, hydraulic fluid entering port 23 is arranged to displace the hollow piston 3 so as to engage a friction lining (not shown) against the disc. The return spring 12 is located between a cover 9 engaging a stop ring 10 and a cylinder 8 supported by a ring 2 against a circlip 4 within the piston 3. The sleeve 19 has three arms 20 (Fig. 2) and rests on a stop ring 11, spring 21 maintaining pin 10 in resilient contact with the 20-45 degrees inclined face 16. The screw 1 is normally adjusted manually by means of a tool-engaging slot 25 so that a gap S, corresponding to the brake clearance, exists between the lower side of arms 13 and ring 2. After the brake lining has become worn, application of brakes will cause the arms 13 to engage the ring 2 so that the engagement of pin 10 with the incline 16 will rotate the screw 1 so as to adjust the clearance. Radial grooves 26 may be formed in the arms 13 and the ring 2. Fig. 3 shows an alternative return spring 12a having ears 28 engaging the ring 2.

Title: Formation of calcium phosphate coatings on ferrous surfaces
IPC: C23C22/78
Filed: 1969-01-15
Abstract: A process of forming a coating of calcium orthophosphate on ferrous surface comprises contacting the surface with an aqueous suspension at a pH of 5 to 9 containing undissolved primary or secondary calcium orthophosphate and then treating the surface with an aqueous acid phosphatizing sulution containing calcium orthophosphate. The suspension may contain 0.5-3g/1 of an alkali metal orthophosphate as a buffer and should contain up to 5g/1 of the calcium orthophosphate which has a particle size of 50% less than 3À5 microns and 90% less than 30 microns. The suspension is preferably made with deionized water, but if tap water is used a softener such as E.D.T.A. or mitrilotriacetic acid is added. Non ionic surface active agents are also added to stabilize the dispersion. The ferrous surface is treated with the suspension for 1 minute up to 100 C. by immersion, flooding or spraying. Treatment is then carried out in conventional aqueous acid phosphatizing solutions containing calcium orthophosphate, nitrates, nitrites, NaOH, chlorates.

Title: Magnetic shuttle drive for continuously progressing sheds in weaving looms
IPC: D03D49/44
Filed: 1969-08-14
Abstract: A shuttle 1 of a travelling wave shedding loom is driven magnetically by magnets 7 in a moving member 9 cooperating with a plurality of similar magnets 5 in the shuttle 1. The side of the shuttle track is formed by a comb 3 into the spaces of which the warps 4 are pressed as the shuttle passes, the side of the shuttle adjacent the comb being faced with a layer of low friction material such as tetrafluorethylene. During motion the poles of the two sets of magnets are displaced so that a pole of a magnet 7 lies opposite the space between a pair of poles of the magnets 5, whereby the attraction and separation between unlike and like poles produce, on each pole of the magnets 5, forces the components of which along the length of the track are all in the same direction to produce a strong driving force whilst at right angles to the track they oppose one another to reduce the force with which the shuttle bears against the comb 3.
Patent ES-375107-A1 (ES)
Title: Supervisory system for unattended repeaters
IPC: H04B17/40
Filed: 1969-12-31
Abstract: A supervisory system for intermediate repeaters enables the gain of a repeater to be determined from either terminal station, and the noise produced by a repeater to be measured from one station without interrupting service. To test for gain, terminal station A(B) transmits a test signal lying in a 1st(2nd) frequency band not used for traffic. At the repeater this signal is converted by a modulator into a signal lying in a 2nd(1st) frequency band, this signal being returned to the A(B) terminal. The repeaters are identified by the frequency of a crystal filter included in the path of the test signals. The circuit can be used with single or double amplifier repeaters.

Title: Static energy reserve for static voltage converters in rail vehicles - has capacitor connected through high resistance to supply wire
IPC: H02J9/06
Filed: 1977-06-25
Abstract: The device has an auxiliary capacitor for current supply before the converter input filter. Its capacitance is much greater than the total capacitance of the input filter capacitors. This capacitor is connected through a resistor to the supply wire. The resistor resistance is so high that the capacitor can be continuously supplied with h.v. even in case of a short-circuit in the capacitor. It is, therefore, designed for the line overvoltages. This overvoltage is a fraction of maximum permissible overvoltages. The capacitor is statically connected to the converter only when the current collector is not in contact with the contact wire. Thus the capacitor is slowly charged when the current collector is in a continuous contact with the contact wire, and delivers energy to the converter during brief interuptions of the current supply.
