Patent ES-484506-A1 (ES)
Title: Universal joint
IPC: F16D3/38
Filed: 1979-09-27
Abstract: A universal joint includes a pair of yokes each having a pair of yoke arms with bores therein. Projecting portions of a trunnion cross extend into the bores of the yoke arms, and a number of bearings are arranged between the projecting portions of the trunnion cross and bearing sleeves which are secured within the yoke arm bores. An elastic seal extends over the radially outward end of each bore relative to the joint axis of rotation so as to close the outward sides of the bores and cover end faces of the projecting portions of the trunnion cross. A supply of lubricant can be contained between each end face and seal to be directed toward the bearings during operation of the joint, as a result of pressure exerted on the lubricant supply by the seal.

Title: Telescoping disconnect switch with gasketed covered access port
IPC: H02G5/06
Filed: 1979-10-31
Abstract: An isolated phase bus disconnect switch has a cylindrical center conductor coaxially disposed in a cylindrical conductive housing having an access port. The edges of the port which are perpendicular to the housing have a conductive gasket of tinned copper braid bolted thereto. A curved conductive cover has a rubber gasket attached to its edges. The cover is removably secured to the housing by a plurality of hold-down hinges attached to the housing which supply sufficient pressure to the cover to seal the rubber gasket and produce electrical contact between the cover and the housing. The electrical path from housing to gasket to cover to gasket to housing eliminates the electrical discontinuity caused by the access port, thus preventing destructive electrodynamic forces between the center conductor and the housing.

Patent ES-8207302-A1 (ES)
Title: Combined shift control.
IPC: F16H63/44
Filed: 1981-11-13
Abstract: A combined shift control for a motor vehicle driveline comprising a change speed gear transmission and a two speed axle whereby, for instance, a five speed gear box with one reverse gear is effectively extended to provide a seven speed driveline with one reverse gear. The gear box includes three parallel shift rods (12, 13, 14) each carrying a respective selector block (15, 16, 17). The slot (18) of the fourth/fifth selector block (17) is deeper than usual so that the gear lever (21) can operate it in two different transverse positions. In the first position the gear lever (21) actuates the fourth and fifth gears, but in the second position, after overcoming a spring-loaded plunger (20) and operating two micro-switches (24) which serve to change the axle ratio to a higher value, the gear lever (21) effectively actuates two further driveline speeds (sixth/seventh) when selector block 17 is caused to move the shift rod 14 to engage fourth and fifth transmission gears again. In order to retain the gear lever (21) in the high axle ratio position when the driver lets go of the lever means such as a slidable gate (22) which is locked into position when the high axle ratio is selected via the micro-switches (24) are provided. Alternate forms of switch and retaining means are described with reference to other Figures. An embodiment is disclosed in (FIGS. 12, 13) for use with a selector finger mounted on a cross shaft rather than a pivotable gear lever of FIG. 4.

Patent ES-8500518-A1 (ES)
Title: Ultra-high-speed relay
IPC: H02H3/40
Filed: 1983-10-21
Abstract: Protective relay apparatus for detecting the direction or distance to a fault from the measuring point on an ac electrical power transmission line using current and voltage deviation signals. The deviation signals represent the changes induced by the fault from the steady-state pre-fault magnitudes. Trajectories are plotted on an X-Y plane using the voltage deviation signal as the X-axis coordinate and the differentiated current deviation signal multiplied by the line reactance to the balance point as the Y-axis coordinate. Due to the use of the differentiated current deviation signal, the trajectories are straight lines. The threshold boundaries for determining the distance to or direction of the fault are time-varying lines of unit slope representing the pre-fault voltage at the fault point. For a fault outside the balance point, the trajectory lags the threshold boundary for a fault at the balance point, the trajectory is always equal to the balance point voltage and for a fault inside the balance point, the trajectory always leads the threshold boundary.

Title: Domestic drinking water installation
IPC: C02F1/78
Filed: 1984-06-01
Abstract: Installation has an ozone prepn. plant for drinking water, and is used esp. in tropical countries where a storage tank holds a certain quantity of drinking water is equipped with the ozone generator in a closed circuit.
