Patent ES-279970-A1 (ES)
Title: Process of purifying aqueous solutions with hydrate formers
IPC: A23L2/12
Filed: 1962-08-10
Abstract: Ice crystals are formed in an aqueous solution by first contacting the solution with a hydrate forming substance to form a hydrate in the solution, then reducing the temperature of the hydrate to the fusion temperature of water in the aqueous solution and decomposing the hydrate while simultaneously forming ice crystals. As shown, sea water from a line 10 is pumped through pre-coolers 14, 16 to a vessel 18 where it is directly contacted with liquid propane from line 20 to form a hydrate, the vessel 18 being cooled by indirect heat exchange with an ice slurry from line 22. Hydrate-brine mixture from vessel 18 then passes through line 26 to a vessel 30 which is maintained at a low pressure and in which the hydrate decomposes and ice crystals are formed, propane vapour released during the decomposition being withdrawn through line 32 under the control of a valve 34 and supplied to a compressor 54. Icebrine slurry is passed through line 36 to a centrifuge 38 where the ice is washed with fresh water from a line 40, then separated and passed through line 44, a repulper 46 in which controlled amounts of product water are added to the slurry and line 22 to vessel 18 where it provides cooling during the hydrate formation and is melted. Part of the resultant water passing through line 24 is supplied to the centrifuge through line 40 and part to a condenser 50 where it directly contacts and partially condenses propane vapour from the compressor 54. The water then leaves the condenser through line 52 and is used in precooler 14 before leaving the process as product water. Liquid propane from condenser 50 passes through line 56 to line 20 while propane vapour passes through line 58 to a second compressor 62, condenser 66 and flash cooler 70, the liquid propane from the latter also being passed to line 20 for use in vessel 18. Propane vapour from the flash cooler is recycled through line 60 to the inlet of compressor 62. Brine leaving the centrifuge 38 through line 42 is used in precoolers 14 and 16 before passing to waste. Cooling for the decomposition of the hydrate may be provided either in the vessel 30 or in line 26 by indirect contact with a refrigerant instead of reducing the pressure in vessel 30. The process may also be used to concentrate fruit juices or waste sulphite liquors and the function of the vessels 18 and 30 may be performed in a single jacketed vessel which is provided with agitators and in which the pressure is reduced after formation of the hydrate.

Title: Hydraulic control devices for braking systems of vehicles
IPC: B60T8/44
Filed: 1965-07-26
Abstract: In a fluid pressure braking system comprising at least one brake cylinder 14, a source of fluid pressure 2 and a unit 4 including a driver actuated slide valve 6 disposed between source and cylinder, the slide valve coacts with a piston 9 housed in a chamber 8 to form a device for damping out the vibrations of the slide valve and the brake cylinder is connected through an auxiliary pipe line 21 to the chamber 8. On actuation of the valve the pressure in the cylinder 14 acts on the piston 9, which has ample clearance in the chamber 8, to provide an upward force on the valve 6 and oppose, together with the force of spring 7, the application force on the pedal 24. On release of the pedal force the former forces raise the valve 6 to connect the brake cylinder with the reservoir line 2 through passages 13, 23, 5 and 21, 22, 23, 5. The latter route provides an arrangement for automatically bleeding the system. The valve 6 may be actuated directly by the driver. Alternatively, two slide valves 6 may be provided and controlled by a compensator lever.

Title: Improvements in or relating to the production of valuable gases
Filed: 1965-10-13
Abstract: Fuel gas is made from a hydrocarbon distillate by a two-stage process, namely: catalytically hydrocracking the distillate in the absence of steam in one zone and gasifying part at least of the products of the hydrocracking in a second zone. The gasification step may comprise a partial oxidation process (not described) or continuous steam reforming with a nickel catalyst and may comprise two reformers in parallel, see Fig. 1 (not shown) one dealing with the lighter fractions of the hydrocracking to produce a CH4-rich gas, and one the heavier fractions to produce an H2-rich gas. The first reformer may be replaced by a thermal hydrocracker, see Fig. 2 (not shown), and the CH4-and H2-rich gases may be mixed together, if desired with an external gas, e.g. LPG, natural gas, refinery gas or tail gas. The flow diagrams (Figs. 1, 2) make clear the complete process, which includes purification, recycling of H2 to the first (hydrocracking) zone and recycling of C11 + fractions to the first zone. The preferred hydrocracking catalyst is silica-alumina with one or more of Group VI and Group VIII metals or their oxides, sulphides and selenides, other supports being mentioned. Preferred feedstocks are those boiling from 200 DEG to 650 DEG F., and products include olefins and benzol. Five specific examples are described.

Patent ES-373516-A1 (ES)
Title: Rf receiving circuits
IPC: H04B1/10
Filed: 1969-11-14
Abstract: A receiver input stage for the reception of RF signals has a parallel tuned circuit including inductance 5 and a variable capacity diode 7 coupling the input signals to the gate of a field effect transistor 9, a first current circuit includes the inductance 5 and the variable capacity diode 7, a second current circuit includes the variable capacity diode and the coupling for the gate and source of the FET 9 and the first and second current circuits are only intercoupled by the variable capacity diode. In the RF amplifier for a radio or television shown i.f. signals are suppressed by filter 3 but interference pulses which would tend to destruct the gate insulation layer 15 pass to the tuned circuit 5, 7 which is tuned to frequencies of the interference pulses which are limited by the variable capacity diode 7. Also these interference pulses have a higher parasitic resonance frequency of a circuit comprising diode 7, capacitors 8 and 20. The input capacity between gate and source and the FET 9 is protected from these parasitic frequencies also by the diode 7. Parasitic inductance 22 in series with the diode 7 must be prevented as this forms a coupling of the parasitic frequency components of the interference pulses to the gate. A small additional protection of the layer 15 can be achieved by connecting in a known manner a limiting diode 23 as shown and a conducting screen 24 may be provided to prevent unwanted coupling. The parasitic inductance 22 can be decreased by using a specially constructed variable capacity diode 7 (Fig. 2a, 2b, not shown), having n and p doped layers (27, 30) and an insulation layer (28) with a conductor (26) connected to the n layer (27) and conductors (34, 35) connected by leads (32, 33) to the player (30). Connections of this diode to the FET of Fig. 1 are described (Fig. 3, not shown). As an alternative to the tuning by the variable capacity diode the inductor 5 may be variable with a constant direct voltage applied to the variable capacitor diode 7. An AGC voltage is applied to a second gate 11 of the MOS FET 9.
