Title: Crystalline metallophosphate compositions.
IPC: B01J27/16
Filed: 1982-06-16
Abstract: A novel family of crystalline, microporous aluminophosphate compositions is synthesized by hydrothermal crystallization at elevated temperatures of aluminophosphate gels containing a molecular structure-forming template. The family comprises a number of distinct species, each with a unique crystal structure. Calcination removes volatile extraneous matter from the intracrystalline void space and yields microporous crystalline adsorbents with uniform pores, the dimensions of which vary, among the individual species, from about 3A to 10A in diameter. The compositions represent a new class of adsorbents of the molecular sieve type, and also exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as catalysts or catalyst bases in chemical reactions such as hydrocarbon conversions.

Patent ES-8501838-A1 (ES)
Title: Generation of energy.
IPC: F01K25/06
Filed: 1983-08-05
Abstract: A method of generating energy which comprises utilizing relatively lower temperature available heat to effect partial distillation of at least portion of a multicomponent working fluid stream at an intermediate pressure to generate working fluid fractions of differing compositions. The fractions are used to produce at least one main rich solution which is relatively enriched with respect to the lower boiling component, and to produce at least one lean solution which is relatively improverished with respect to the lower boiling component. The pressure of the main rich solution is increased whereafter it is evaporated to produce a charged gaseous main working fluid. The main working fluid is expanded to a low pressure level to release energy. The spent low pressure level working fluid is condensed in a main absorption stage by dissolving with cooling in the lean solution to regenerate an initial working fluid for reuse.

Patent ES-8707056-A1 (ES)
Title: Variable bandwidth handsfree telephone using switched capacitor filtering
IPC: H04M1/60
Filed: 1986-03-26
Abstract: This invention is a technique for providing isolation between the two channels of a handsfree telephone subset without resorting to gain switching or gain variations in the transmission path. The invention involves separating the frequency spectrum into two portions and allowing the stronger signal to capture a major portion of that available spectrum. Switched capacitor filters are used to control the degree of frequency bandwidth allocated to each channel while the filters are clocked from a common source assuring no possibility of overlap in the frequency spectrum. The affect of varying the bandwidth is much less noticeable than varying the amplitude and, therefore, creates much less user irritation.
Patent ES-8703356-A1 (ES)
Title: Improvements in hydraulic anti-skid braking systems for vehicles.
IPC: B60T8/50
Filed: 1986-05-16
Abstract: In an anti-skid braking system a modulator for modulating the supply of hydraulic fluid from a master cylinder to a brake incorporates a flow-control regulator valve and an exhaust valve which is responsive to signals from a sensor. When the exhaust valve is closed the regulator valve is in a first position to permit unrestricted direct flow through it and when the exhaust valve is open a variable orifice in the regulator valve provides a restricted flow through it. The exhaust valve and the valve are only connected hydraulically and a conventional inlet valve normally operated directly by the sensor is omitted. The construction is therefore simplified since relative position tolerances are otherwise eliminated.
