Patent ES-374104-A1 (ES)
Title: Reduction of turn-on delay in liquid crystal cell
IPC: G02F1/1365
Filed: 1969-12-01
Abstract: To reduce the time required for a nematic liquid crystal cell to change from its transparent state to its light scattering state in response to repetitive voltage pulses of relatively short duration, a number of such pulses being required to cause the liquid crystal to scatter light to an extent which is a function of the amplitude of the pulses, the internal resistance of the cell is increased prior to the application of the repetitive pulses. To increase the internal resistance of the cell the number of free current carriers present in the liquid crystal is reduced by applying either a continuous direct voltage bias (Figs. 8 and 9, not shown) or a continuing train of voltage pulses (Figs. 10-12, not shown) to the cell at a level lower than the voltage threshold for dynamic scattering of the cell. By increasing the internal resistance it is found that the number of excitation pulses necessary to effect a substantial amount of light scattering is reduced, i.e. the " turn-on " time for the cell is reduced. In addition, the cell exhibits a larger scattering effect and is thus brighter. The liquid crystal cells may be arranged in a matrix to form a television type display, and in every frame interval a row of cells is simultaneously " addressed," i.e. have their internal resistances increased, while pulses having amplitudes corresponding to the video information of respective elements of the row are applied to the cells.

Patent ES-382777-A1 (ES)
Title: Fluid pressure gauge
IPC: G01L7/08
Filed: 1970-07-31
Abstract: A gauge for measuring the air pressure in vehicular tires has a lower compartment filled with a body of water and an upper compartment normally communicating with the outer atmosphere either directly or through a slack diaphragm. An upwardly closed viewing tube calibrated in units of pressure has a lower end opening into the upper chamber above the normal water level so as to be normally vented to atmospheric pressure. An inlet port in the lower compartment is connectable to the inflated tire whereupon the entering air drives the water past the entrance end of the viewing tube and thereafter closes the upper compartment against the atmosphere (by closing a hydraulic valve or deflecting the slack diaphragm against an apertured lid) so as to prevent the escape of the water therefrom and to build up a rising counter-pressure in that compartment forcing part of the water into the tube.

Title: Uranium complex recycling method of purifying uranium liquors
IPC: C22B3/00
Filed: 1974-10-31
Abstract: Uranium is separated from contaminating cations in an aqueous liquor containing uranyl ions. The liquor is mixed with sufficient recycled uranium complex to raise the weight ratio of uranium to said cations preferably to at least about three. The liquor is then extracted with at least enough non-interfering, water-immiscible, organic solvent to theoretically extract about all of the uranium in the liquor. The oganic solvent contains a reagent which reacts with the uranyl ions to form a complex soluble in the solvent. If the aqueous liquor is acidic, the organic solvent is then scrubbed with water. The organic solvent is stripped with a solution containing at least enough ammonium carbonate to pecipitate the uranium complex. A portion of the uranium complex is recycled and the remainder can be collected and calcined to produce U3O8 or UO2.

Title: Hopper gate for self-unloading ships
IPC: B65G47/18
Filed: 1976-12-22
Abstract: A belt feeder gate for use in self-unloading ships of the type in which the hold of the ship is provided with a hoppered bottom including a plurality of hoppers overlying an unloading conveyor belt moving lengthwise of the ship. Each open hopper bottom is closed by a gate comprising two wheeled gate sections which are movable relative to each other along stationary tracks in a horizontal plane and in a direction laterally of the direction of travel of the underlying unloading conveyor belt. The respective longitudinally opposite wheeled ends of the respective gate sections project in underlying relation to longitudinally spaced "hog ridges" defined by the walls of adjacent hoppers, each "hog ridge" being an inverted V-shaped hollow space defined beneath two upwardly converging oppositely longitudinally inclined walls of two longitudinally adjacent discharge hoppers. The stationary tracks on which the wheeled gates move are also in underlying relation to, although not within, the respective "hog ridges," and the hydraulic rams which impart movement to the gate sections are housed within the "hog ridges." A further feature of the construction is the V-shaped axial cross-section of the wheels on the gate sections, which V-shaped cross-section rides on an inverted V-shaped track to prevent "play" or wobble of the wheeled gate relative to the tracks, thereby providing a constant and stabilized linear relation of the wheeled gate relative to the power means such as a hydraulic ram, which imparts movement to the gate sections.

Title: Piston ring assembly
IPC: F16J9/06
Filed: 1979-05-23
Abstract: Disclosed is a piston ring including a spacer-expander spring member. In a preferred embodiment the ring is of cast iron and includes two axially spaced cylinder wall contacting lands. At least one generally rectangular inwardly facing spring receiving recess is formed in the interior wall of the ring to receive the spring member which is formed from a flat strip of metal in a "U" configuration with the legs thereof facing outwardly, peferably aligned with the lands on the ring.
