Patent ES-485294-A1 (ES)
Title: Labyrinth trim valve
IPC: F16K47/02
Filed: 1979-10-23
Abstract: A fluid flow restrictor for use in a high pressure valve or the like which comprises a series of closely interfitting concentric cylinders alternately attached to the valve seat and an axially movable valve plug of the valve. In one advantageous embodiment of the invention, various arrangements of slot openings are formed through the several cylinders. The slot openings may be of any geometric shape, for example, rectangular or trapezoidal, and are of sufficient volume to act as expansion chambers for a compressible fluid. The openings of each cylinder communicate with the openings of an adjacent cylinder by various overlapping relationships between openings or by viscous friction flow paths between the cylinders to form restricting flow paths therebetween. Axial displacement of the valve plug will move the interfitting cylinders with respect to one another to vary the flow path dimensions between the slot openings of the cylinders. In another specific form of the invention, the interfitting cylinders are slotless, providing a viscous friction flow path between cylinders and expansion chambers above the open ends of each cylinder and between adjacent cylinders.

Patent ES-8204147-A1 (ES)
Title: Control system for regulating large capacity rotating machinery
IPC: F04D27/00
Filed: 1981-01-19
Abstract: The control system disclosed herein regulates a centrifugal compressor which has inlet guide vanes adjustable to vary the compressor capacity. A variable speed motor is connected to drive the compressor, and variation of this motor speed provides another input for regulating the compressor capacity. A control system achieves optimum energy efficiency, while avoiding surge, by the manner in which the motor speed and the inlet guide vane positions are regulated. To do this, a control signal must be derived to indicate the compressor head value. This signal is achieved by providing two signals, one related to the absolute condenser pressure, and the second related to the absolute evaporator pressure. The control system operates on these two signals to provide a third signal which is a function of a ratio, in which the numerator is the difference between the condenser and evaporator pressures, and the denominator is the evaporator pressure. Alternative measurement and processing techniques are described. This signal affords a very good indication of the compressor head and thus achieves increased efficiency of system operation, with consequent energy conservation, especially at lighter loads and low heads.

Title: Process for the preparation of vinyl chloride.
IPC: C07C17/38
Filed: 1982-09-03
Abstract: Operational improvements in the preparation of vinyl chloride by thermal cleavage of 1,2-dichloroethane. To date, the utilisable products of this cleavage process were cooled directly to 25 to 30 DEG C after having left at a quench tower at temperatures around 130 DEG C, followed by working-up by distillation. According to the invention, the cooling process is carried out in two steps, the first step being used for gaining energy. In this two-step cooling process, however, an additional formation of butadiene takes place, this problem being solved according to the invention by feeding iron- and chlorine-containing 1,2-dichloroethane to the particular stream of dichloroethane which acts as the reflux of a column for high-boiling components, in which the bottom of the quench tower is worked up.

Title: Adjustably metered transfer of resin increments in folded bed ion exchange systems.
IPC: G01F11/28
Filed: 1984-05-28
Abstract: Liq.-contg. increments of ion exchange resin granules are expelled from the end of a column in a moving folded bed ion exchange system in metered volumes. The column has a resin inlet and a resin outlet at opposite ends and is completely filled with compacted resin granules contg. liq. within and between them. The granules are forced into the column under hydraulic pressure thus displacing packed liq.-contg. resin from the outlet which passes into the lower portion of a metering chamber until the granules reach the level of the underside of a screen fitted across the chamber. Liq. passes through the screen to a predetermined height which is sensed along with the increased liq. pressure below the screen to generate a signal stopping the hydraulic pressure, a precise increment of resin granules being packed in the chamber. The increment is subsequently transferred to another unit in the system.

Abstract: A fusion-bonded matrix coating on endless, flexible metallic casting belts for continuous casting machines is described. The fusion-bonded matrix coating comprises a nonmetallic refractory material interspersed substantially uniformly throughout a matrix of heat-resistant metal or metal alloy, for example nickel or nickel alloy, The coating is applied to a revolving belt (10,20) being supported and driven by pulleys (34,36) in a machine by thermally spraying a powdered mixture directly onto the roughened casting surface of the belt, The machine holds the revolving belt under tension and applies cooling to the rear surface of the revolving belt (10,20) opposite to the region where the thermal spray gun (66) is applying the coating to the belt (10,20), and causes the thermal spray gun (66) to traverse uniformly transversely across the belt. The result is to insulate and protect the underlying belt from intimate molten metal contact. The life of the coated belts is dramatically increased, and the surface quality and properties of the cast product are significantly improved.
