Patent ES-321260-A1 (ES)
Title: Improvements in evaporators for the distillation of sea water
IPC: B01D1/06
Filed: 1965-12-29
Abstract: Liquid, e.g. sea water, is distilled in a multiple effect evaporator comprising a series of metal plates 1 arranged face to face with spaces between them forming a series of cells 2, the whole series being disposed between a steam chest 23 and a condenser chamber 26. The cells are maintained under reduced pressure by pump 39. Sea water supplied through pipe 13, is distributed through pipes 11 and slots (not shown) so that it flows as a film down the right-hand side of each plate 1. The left-hand side of the first plate is heated by steam chest 23, and the vapour given off from the waterfilm on the other side of the plate flows across the cell 2 and condenses on the opposite plate and thus supplies heat through this second plate to the water-film flowing down its righthand side in the second cell. This same process of evaporation and condensation takes place in the following cells, but in the last cell the vapour condenses on the plate bounding the condenser chamber 26. The bottom of each cell is divided into two adjacent troughs by a vertical plate (not shown). Unevaporated water is withdrawn from the left-hand troughs through pipes 15 which lead to a common pipe 20. Distilled water is withdrawn from the righthand troughs through pipes 17 which lead to a common pipe 22. The unevaporated water and the distillate are withdrawn from the system via pipes 43 and 44, respectively, which pass through heat exchanger 38. The sea water to be distilled is pumped through heat exchanger 38, and is thereby preheated before it reaches to tops of plates 1. The distillation of ethyl alcohol, acetone and toluene is referred to. The recovery of butyl acetate from water is mentioned.

Patent ES-338868-A1 (ES)
Title: Strengthening of oxidized soda-lime glass articles
IPC: C03C21/00
Filed: 1967-04-04
Abstract: Glass articles having a composition including 7-25% wt. Na2O and 45-80% wt. SiO2 are strengthened by ion-exchange desorption of copper ions which are not induced to metallic copper and which therefore impart no significant colour to the heated article. Preferably the layer so produced should be deeper than any Griffith flaws and abrasion marks that may reasonably be expected in use. An aqeuous halogen is used and is preferably diffused into the glass above its annealing temperature and the layer thus produced is placed in compression when the article is cooled, but the introduction may be made at a lower temperature and subsequent heating and cooling performed. The treatment should be carried out in a non-reducing atmosphere.

Patent ES-369030-A1 (ES)
Title: Safety closure for high pressure gas tanks
IPC: F16K1/30
Filed: 1969-07-01
Abstract: A safety closure and coupling 10 for the opening in a high-pressure gas container T, e.g. a scuba diving bottle, comprises a container sealing portion 12, which may screw into container T, enclosing flow passage 14 connecting a safety flow valve body 62, which fits into the container, with a shut-off valve 28 and an external connection 24. The flow valve member may comprise a ball 78 of non-corrosive material held away from valve seat 76 by spring 74, so that gas may flow through drillings 82, past ball 78 to passages 66, 14 and 16. A gas flow in excess of a limit predetermined by the strength of the spring and the geometry of the valve, e.g. caused by a rupture of closure 10, forces ball 78 against seat 76, thus restricting the gas flow to the small amount passing through by-pass 84. The by-pass 84 guards against pressure buildup when the tank is heated, e.g. in a fire, both by removing gas from the tank and by the cooling produced by expansion of the gas flowing through the by-pass. Extension 64 is preferably made of brass or other high thermal conductivity metal to aid heat transfer to the vented gas. In the embodiment shown rotating stop valve 28 in valve seat 20 by means of knob 48 connects passage 16 via counterbore 18 to passage 22 and thus to external connection 24. Passage 16 may contain a safety plug 58 of soft metal designed to blow out if the pressure in 16 exceeds 2500 p.s.i. at 100 F., and at a lower pressure at higher temperatures, to provide protection for the tank in case of fire. A back pressure valve (90, Fig. 2, not shown) having a closure (98) may be inserted into the flow passages (92, 22a) between the stop valve and the external connection, so that a spring (100) closes the valve when the pressure in passage (92) drops below 300 p.s.i. The user, e.g. a diver, having been thus warned by cessation of the gas flow that his gas supply has decreased to 300 p.s.i., turns a lever (126) to lift the valve closure member (98) off its seat (96), and makes use of the remaining gas. In another modification, the safety closure is so dimensioned that it may be enclosed within a cap (148, Fig. 3, not shown), screwed on to the gas container T, and the safety plug of soft metal is replaced by a rupture disc (13b) held over the open end of the passage (16b) by a masher (138).

Title: Means responsive to road surface conditions for selecting adaptive braking system control channel controlling wheel
IPC: B60T8/84
Filed: 1969-12-16
Abstract: In a brake antiskid system including a control channel for controlling the brake force simultaneously on a first and second vehicle wheel in response to a selected control signal and including means for generating signals proportional to the rotational velocities of the first and second wheels respectively, the control signal selection device comprises circuitry, responsive to the signals, for sorting the signals and causing a low voltage signal to be produced on one terminal and a high voltage signal on another terminal, a comparator responsive to the signals for generating a primary error signal whenever the ratio of the signals exceeds a predetermined value and means responsive to the error signal for sampling the terminals, the sample comprising the selected control signal. Wheel sensors 6, 10 generate pulses at a level related to wheel velocity and the pulses are converted to a D.C. voltage level, proportional to wheel speed, in counters 8, 12 to provide on terminals 8a, 12a D.C. voltage levels proportional to the rotational velocity of the left and right wheels respectively, these signals being sorted by circuits 14, 16 so that the low speed signal always appears on terminal 18 and the high speed signal on terminal 20. A comparator 24 such as a differential amplifier has applied thereto the left wheel voltage signal directly and the right wheel voltage signal attenuated by resistors 26, 28, another comparator 34 having applied directly thereto the voltage on terminal 12a and the attenuated voltage from terminal 8a and the outputs are fed through respective diodes 36, 38 to a power stage 40 which can energize a relay coil 22b and cause relay pole 22a to contact terminal 20 instead of terminal 18. When the wheel speeds are similar within predetermined limits, power stage 40 has no output and control channel 42 is connected to the low velocity terminal 18 but when they differ by a predetermined amount the channel 42 receives the high speed voltage signal.
