Patent ES-304195-A1 (ES)
Title: Evaporator for concentrating radioactive solutions
IPC: B01D3/00
Filed: 1964-09-19
Abstract: An evaporator for concentrating radio active solutions, e.g. a solution of a plutonium salt, comprises a vessel 202 connected by branch-tubes 216 and 222 to an external heater 220 of the rising- film type. The boiling solution enters the vessel 202 tangentially through branch 222, the separated vapour flows out of the top of the vessel, and the liquid is returned to the heater through branch 216. Liquid droplets are removed from the vapours rising up vessel 202 by means of Raschig rings made of glass comprising B2O3. There may be four heaters, each containing three electric immersion heaters 228. The bottom of vessel 202 is connected to branch-tubes 216 by a vertical annular tube 204. The solution-to-be-concentrated is introduced into the apparatus through pipe 212 and the concentrated solution is withdrawn through conduit 226, and means may be provided for regulating the level of the solution in vessel 202. The vapours pass from the top of vessel 202 into cyclone separator 234 where any residual liquid droplets are separated. This liquid is returned to the evaporator through pipes 238 and 212. The dry vapours leaving the cyclone are conducted to condenser 242. In order to absorb neutrons and gamma radiation, blocks of cadmium or polythene 250, 252 are disposed as shown. Provision may be made so that the apparatus is automatically made inoperative if crystallization occurs in the solution.

Title: Shaking-funnel device for the gravity concentration of solid particles
IPC: B03B5/04
Filed: 1965-01-21
Abstract: An apparatus for the gravity separation heavy and light materials of practically the same size comprises a container 1 having a wide-angled, funnel-shaped bottom or diaphragm 2 provided with an outlet port 10 at its lower part, an outlet duct 14 opening in the container a certain distance above the port 10, means for mounting the container, means for imparting a combined gyratory and vibratory movement to the container and a pipe 15 and a conical baffle 16 for feeding the mixture of materials, either in the dry state or in water, to the periphery of the container. Due to the conicity of the bottom or diaphragm 10 and to the gyratory and vibratory movement of the container, the materials to be separated tend to flow or settle with different settling speeds along spiral paths towards the outlet port 10 but due to the difference in settling speeds, they separate into a lower layer of heavy material which is removed through the port 10 and a channel 13 and into an upper layer of light material which is removed through the duct 14 by means of a pump P. A valve 11 on an adjustable lever 12 controls the discharge through the port 10. The container is supported on a member 3 mounted on the pins 4 of three cranks 5 mounted on a framework 6 and driven by a motor 8 through a belt 9 and gears 7. The construction of the cranks, the gears and the framework is sufficiently rough and have such a play as to vibrate the container when the latter is driven. The throw of the cranks may be adjustable. In a modification, the pipe 14 may be introduced from below through a wider central port 10. In another modification, the pipe 14 is introduced centrally from below but the discharge for the heavy material is through a number of openings provided in the bottom 2 around the pipe 14. In a further modification, the pipe 14 penetrates through the side wall of the vat as shown in dotted lines and may be slightly inclined or horizontal and may be provided with a downwardly bent end opening above the port 10. In another embodiment, Fig. 8, the container 1 is divided internally by a number of funnel-shaped diaphragms 2 vertically spaced above a bottom 2, each diaphragm and the bottom having a central discharge port 10. A discharge duct 14 opens above each port and a conical baffle 16 is provided above each diaphragm and the container bottom. In a further embodiment. Fig. 9 (not shown), the container is suspended from a support and the driving cranks may be slightly inclined to increase the vibrations imparted to the container.

Title: Composition for the Determination of Enzymes
IPC: C12Q1/37
Filed: 1968-09-06
Abstract: A composition for the determination of amino acid arylamidase (leucinaminopeptidase) comprises (a) alanine hydrazide, alanine pnitroanilide or alanine-#-naphthylamide, (b) a buffer solution with a pH of 6.5 to 7.5, with or without (c) an aromatic aldehyde colour reagent, for example p-dimethylamino-benzaldehyde. In use, the sample, for example blood serum, is incubated with the substrate and the buffer solution. When alanine p-nitroanilide is used, the p-nitro-aniline formed is determined colorimetrically, optionally in a kinetic test. When alanine hydrazide or alanine-#-naphthylamide is used, the hydrazine or #-naphthylamine formed react with the aromatic aldehyde colour reagent and the solution is acidified to give a coloured salt, the extinction of which is measured. A test pack contains solutions of the alanine derivative and of the buffer, optionally mixed together, with or without a solution of the colour reagent.

A squelch circuit 46, Fig. 3 (not shown) receives the output of amplifiers 15, 16 and the A.G.C. voltage and normally biases diodes 3, 4 to be conducting, but when the ratio of the carrier levels is equal to or exceeds 7.8 db the appropriate diode 3 or 4 is biased off to block the weaker channel and an alarm is operated. For use in a space diversity system, switches 31, 32, 33, 34 are in the position shown. For frequency diversity, the switches may also be as shown, the local oscillator frequencies being adjusted accordingly, or switches 31, 32 may be operated to connect a common aerial 35. For time diversity, the carriers may have closely spaced frequencies or cross-polarization techniques may be used and a delay 38 is connected into one channel to bring the two channels into time coincidence. Provision also is made for an angle diversity system, an antenna 41 including a reflector and horns 43 providing narrow highly directional beams being connected by operation of switches 31, 32.

Title: Method for the combustion of sulphur
IPC: C01B17/54
Filed: 1972-03-09
Abstract: A method and an apparatus for the combustion of liquid sulphur in a combustion chamber. The injection device for the liquid sulphur and the primary air comprises a double spraying arrangement: a simple mechanical spraying device in which the liquid sulphur is driven through a spray nozzle without the aid of an auxiliary driving fluid and a pneumatic spraying device in which a turbulent rotational primary air stream mixes with the relatively coarse spray produced by the spray nozzle through a constriction zone and into the combustion chamber, transforming the relatively coarse spray into a relatively fine spray. The fine spray enters the combustion chamber at the apex of a conical end wall of the combustion chamber and is driven into contact with the conical end wall due to the whirling action of the primary air. Secondary air is introduced along the lateral walls of the combustion chamber, in order to protect these walls of refractory material from the radiation heat produced during combustion.

Title: Method of, and apparatus for, manufacturing a video record
IPC: G11B7/24097
Filed: 1976-03-22
Abstract: When the information of a continuous-motion video record is displayed in the stop-motion mode by repeated display of two fields which form an interlaced picture, motion in the scene gives rise to a frame-frequency flicker phenomenon in the stop-motion picture. By forming suitable video signal combinations in discrete groups which each comprise two associated fields and by recording these combinations in the video record, the flicker phenomenon in a stop-motion picture is eliminated without continuous display being perceptibly affected.

Title: Method of starting a combustion system utilizing a catalyst
IPC: F23C13/00
Filed: 1978-01-02
Abstract: A method and system are provided for starting a combustion system utilizing a catalyst, and at the same time provide low emissions of unburned hydrocarbons and carbon monoxide.The method is particularly applicable to starting such combustion systems which are subject to intermittent operation, such as for example, gas turbines used to power automotive vehicles in which carbonaceous fuels are combusted to provide the motive fluid, or furnaces which are used intermittently.
