Patent ES-8501887-A1 (ES)
Title: Ultra-high speed protective relay apparatus and method for providing single pole switching
IPC: H02H7/26
Filed: 1983-08-01
Abstract: Protective relay apparatus and method for determining the faulted phase conductor of a three-phase ac electrical transmission line. The voltage and current on each conductor are measured and the steady-state ac electric power signal removed. The resulting filtered-voltage signals are multiplied by the characteristic admittance of the transmission line and then combined with the filtered-current signals to produce three current signals representative of the current on each conductor caused by an incident traveling wave and three current signals representative of the current on each conductor caused by a forward traveling wave. A comparator compares the six current signals to provide an indication of the direction to the fault and to provide an enable signal when the fault is on the protected line segment. The three incident-wave current signals are filtered to provide a modal signal representing the total current produced on the transmission line by a first propagational mode of the incident traveling wave. A discriminator processes the three incident-wave signals, the modal signal, and the enable signal to provide an indication of the faulted phase conductor.

Title: Improved water thickening agents.
IPC: C09D11/00
Filed: 1983-09-22
Abstract: Polymers of 98.9 to 95.5 weight percent of olefinically unsaturated carboxylic acids containing at least one activated double bond, 1 to about 3.5 weight percent of an alkyl acrylate ester of acrylic or methacrylic acid wherein the alkyl group contains 10 to 30 carbon atoms and 0.1 to less than 1 weight percent of a crosslinking monomer, are efficient thickeners in many applications where high ionic environments are encountered and may be used at lower concentrations to obtain equivalent or better results than prior art thickeners, and have been found to be particularly effective in print paste applications wherein there are reactive dyes, direct dyes and disperse dyes with high and varying ionic content. Further, in screen printing, improved print pastes are provided when they contain the novel polymers of this invention that have better rheology with less bounce back on release of printing pressure, and textile prints so made have better penetration. The resulting prints have an excellent combination of sharpness, lack of wicking, penetration, levelness and color yield.

Title: Pressure pulse generator.
IPC: E21B47/18
Filed: 1984-10-23
Abstract: Pressure pulse generator used for communicating information between points a well bore through fluid flowing in a tubing string, comprises (a) a housing connected in the string so that fluid flowing in the string partially flows through the housing; (b) a fixed stator within the housing; (c) a rotatable rotor within the housing adjacent the stator, so arranged that both the rotor and stator have spaced lobes so providing a number of ports allowing fluid passage, the movement of the rotor with respect to the stator creating maximum and then minimum fluid passage-ways, and hence fluid flow through the housing will be interrupted to cause the generation and transmission up stream of a pressure pulse signal; and (d) means for establishing fluid dynamic forces in response to the flow of fluid through the housing that bias the rotor generally into an orientation in which the ports provide the greatest fluid passageway. The dynamic forces are developed from the fluid flow by providing each lobe of the rotor with sides outwardly tapered in the downstream direction and with underlap relative to the stator lobes. The taper on each side of the rotor lobes is preferably in the range of 8-30 degrees with respect to the vertical axis.

Title: Strand storing and delivering device.
IPC: B65H51/20
Filed: 1985-05-31
Abstract: A simplified strand storage and feeding device having a rotatable spool (14) about which a traveling yarn (Y) is transiently wound while being fed to a textile machine, utilizes a novel driving arrangement for rotation of the spool (14), including a pulley (12) operatively affixed to the spool (14) and having plural radial teeth (34) circumferentially spaced about one side of a belt receiving recess in the pulley and a driving belt (35) having compatible edge notches meshing with the pulley teeth (34). The edge notched configuration of the belt (35) provides positively timed driving of the device while also being splicable by mechanical interconnection of separate belt ends, so that the belt (35) may be of non-endless form for ease of installation and breaks therein may be easily repaired by splicing. A slidably movable yarn withdrawal guide eyelet (92) is provided for withdrawing yarn from the spool (14) either tangentially or generally axially therefrom for operation of the device in either a positive or demand feeding mode. Two forms of pulley and spool assemblies are disclosed which eliminate the use of a separate yarn winding displacement member and are resultantly simplified, compact and less expensive than conventional devices.
