Patent ES-372144-A1 (ES)
Title: Service and emergency brake control valve
IPC: B60T15/04
Filed: 1969-10-03
Abstract: A control valve for a fluid pressure braking system having normal and spring applied, fluid-released emergency brakes is operated in two stages, one for normal braking and the other for controlled emergency application of the spring applied brakes when fluid pressure in the normal braking circuit falls below a predetermined level. The valve has upper and lower sections 10, 14 controlling the supply of fluid to the normal brake chambers 32, 34 and emergency brake chamber 36 respectively by way of outlets 26, 78 and inlets 18, 58 connected to service and emergency reservoirs 22, 62. In normal operation when the driver depresses a pedal 42, a piston 38 is also depressed and valve seat 44 of a self-lapping valve engages a combined delivery and exhaust valve member 45 of a sleeve 48, a connection between a delivery cavity 24 and atmosphere through a bore 46 in the sleeve being interrupted. On further depression of piston 38, seat 44 forces sleeve 48 downwardly causing valve member 45 to disengage seat 50 thereby establishing connection between brake chambers 32, 34 and service reservoir 22 via conduit 20, inlet port 18 and cavity 24. Service reservoir 22 also communicates by a branch conduit 88 with the underside of a piston 90 biased upwardly by a spring 84, the fluid pressure which passes to release chamber 34 acting on the piston 90 upper face. In normal operation the downward force of a plunger 96, rigidly secured to piston 38, on piston 82 is not sufficient to overcome the combined force of spring 84 and the upwardly acting fluid pressure and the emergency brakes are held released by fluid pressure from reservoir 62 passing to chamber 36 via manual valve 60, conduit 58, chamber 56, chamber 76 and port 78. If fluid pressure in the reservoir 22 decreases below a predetermined value the downwardly acting plunger force on piston 82 causes the latter to move downwardly and an extension 80 thereof causes a valve member 68 of a further self-lapping valve and carried by a sleeve 71 to engage a seat 66 under the action of a spring 74 to disconnect reservoir 62 and chamber 36. Further movement of extension 80 disengages member 68 from a seat 92, fluid pressure in chamber 36 being partially vented to atmosphere by way of port 78, chamber 76, channel 64, sleeve bore 71 and port 54. The force of spring 64 temporarily overcomes the combined downward pressure of plunger 96 and chamber 34, pressure and member 68 engages seat 62. The process is repeated as the pedal is depressed. In a further embodiment plunger 96 engages a snap ring (100), Fig. 2 (not shown), carried by hollow extension 98 of piston 82, having Belleville washers acting between the piston and a section (97) of the extension engaging the plunger.

Title: Pressurized-water coolant nuclear reactor steam generator
IPC: F28D7/16
Filed: 1973-06-25
Abstract: A pressurized-water coolant nuclear reactor steam generator has a vertical housing for the steam generating water and containing an upstanding heat exchanger to which the pressurized-water coolant passes and which is radially surrounded by a guide jacket supporting a water separator on its top. By thermo - siphon action the steam generating water flows upward through and around the heat exchanger within the guide chamber to the latter's top from which it flows radially outwardly and downwardly through a down draft space formed between the outside of the jacket and the housing. The water separator discharges separated water downwardly. The housing has a feed water inlet opening adjacent to the lower portion of the heat exchanger, providing preheating of the introduced feed water. This preheated feed water is conveyed by a duct upwardly to a location where it mixes with the water discharged from the water separator.

Patent ES-456507-A1 (ES)
Title: Low friction balanced piston ring
IPC: F02F5/00
Filed: 1977-03-03
Abstract: A low friction piston ring of split annular construction has a circumferentially extending recess formed at its upper outer portion to define an outer radial ledge which divides the outer axial surface of the ring into a recessed outer face and a reduced (as compared to the total outer axial surface) bearing surface. The bearing surface preferably has a wear resistant coating thereon. The outside diameter of the recessed outer face is less than the outside diameter of the bearing surface by an amount at least equal to the radial wear depth of the bearing surface. A peripheral recess is also formed at the upper-inner portion of the ring to reduce or eliminate torsional twisting of the ring. The ring provides a reduction in frictional resistance between the ring and the cylinder wall, good sealing against gas blow-by and enhanced engine performance and exhaust emissions control.

Patent ES-472057-A1 (ES)
Title: Valve operator
IPC: F16K31/383
Filed: 1978-07-26
Abstract: An actuator for actuating valves and the like which comprises a pair of opposed cylinders, the axes of which are generally perpendicular to a valve stem. Pistons in the cylinders are connected to the valve stem by toggle links, the pistons being resiliently urged toward the center of the assembly which corresponds to a closed valve position. To open the valve, a fluid, such as air, is introduced between the pistons, so as to move them away from their rest (valve closed) positions. A handwheel is provided to manually open the valve by moving the pistons from their rest positions. A solenoid controlled pneumatic valve may be used to control the supply of air to the actuator. Either a failure in air pressure or an electrical failure will result in the pistons being urged to the rest positions and also result in closing the connected valve, i.e., the failure mode.

Title: Anti-stall controller.
IPC: F04B49/06
Filed: 1980-01-07
Abstract: Control system for a hydrostatic transmission of the type including a prime mover driven variable displacement pump, the displacement of which is controlled by a pair of strokers (28, 30). Flow of pressurized control fluid from the charge pump to one of the strokers, and from the other stroker to tank, is controlled by a main control valve (34). The control system includes an auxiliary control valve (44) defining passages (98, 100, 102) communicating between the lines connecting the main control valve and the strokers. The auxiliary control valve includes an on-off, electro-hydraulic valve (46) which prevents flow through the auxiliary valve in response to an electrical signal in one condition, and permits flow in response to an electrical signal in another condition. The electrical signals to the electro-hydraulic valve are generated by control logic (52) which alternates the electric signal between the one condition and the other condition at a duty cycle which varies proportional to the amount of pump destoke needed to prevent stalling of the prime mover.
Patent ES-488115-A1 (ES)
Title: Soaker hose
IPC: B29C48/38
Filed: 1980-01-31
Abstract: A porous flexible hose primarily of crumbed rubber and synthetic rubber reclaimed from rubber tires, ground to a relatively small granular size, with metal removed such as, for example, would pass through a 30-mesh screen, process-mixed through an extruder, with a much smaller binder mix of primarily polyethylene, in the order of 25% by weight, and with approximately 0.5% of the mixture added sulphur and 0.5% oil that can be random mixed grades of automobile engine oil. The resulting product is useful as a soil watering soaker hose that has a high degree of flexibility along its length. It is a water leaking soaker hose formed in the process through the extruder with limited foaming from steam originating from absorbed moisture in the crumbed, reclaimed rubber tire material, and from residual gases venting from the material mix, with product mix heating in the extruder, forming some open cell fluid flow paths. The foaming with steam and gases from the mix also form labyrinth passageways between the rubber tire granules and the polyethylene binder mix, and also through the binder mix that is non-compatible with the rubber granules but that forms a physical interconnective structural material binder therefor.
