Patent ES-344280-A1 (ES)
Title: Vapor generating apparatus
IPC: F22B35/00
Filed: 1967-08-21
Abstract: In a vapour generator in which liquid supplied at 38 flows through an annular downcomer space 29 into a vertical vapour generator shell 17 in which the liquid is evaporated by heating tubes 18, an adjustable ring 45 is provided in the downcomer space.

Patent ES-353354-A1 (ES)
Title: Process for preparing chlorine-free nitric acid solutions
IPC: C01B21/46
Filed: 1968-04-30
Abstract: Chloride ions are removed from a nitric acid solution containing nitrosyl chloride and optional solids by passing a gas which under the reaction conditions does not react with the nitric acid solution e.g. oxygen, nitrogen or air through the solution and blowing out the bulk of the nitrosyl chloride in the gas phase, adding dinitrogen tetroxide in excess amount relative to the residual chloride ion content and then completing the blow out process. The blowing out process may be carried out at 20-50 C. and preferably a pressure of 0.1 to 1 atmospheres absolute. The amount of dinitrogen tetroxide added may be 0.4 to 0.7 times the amount of nitrosyl chloride contained in the nitric acid solution used as the starting material. In the examples potassium nitrate, nitric acid and nitrosyl chloride are introduced at the head of a plate column and oxygen is simultaneously introduced at the bottom of the column. Liquid N 2 O 4 is added dropwise half way down the column.
Patent ES-353617-A1 (ES)
Title: Improvements relating to Filter Presses
IPC: B01D25/176
Filed: 1968-05-07
Abstract: A filter press plate with a central feed aperture (Fig. 1, not shown) has an array of projections 4a, 4b, extending outwards from its web 2 to level with its peripheral frame (1), projections on adjacent plates abutting when the press is closed, to prevent webs 2 deforming if different pressures exist in adjacent chambers. Projections may be integral with the webs 2, as in Fig. 2 (not shown), or may screw together as a nut and bolt through web 2. Washers 11 ensure that projections project the correct distance from the web, and grooves 5 receive the filter cloths 6, retained by elastic rings 7.
Patent ES-354085-A1 (ES)
Title: Device for encoding a list of terms
IPC: G11C17/00
Filed: 1968-05-18
Abstract: In a coding device, an alphabetically arranged list of terms is disposed on a rotary disc 1 in the form of a spiral of constant pitch. On the other side of the disc, in opposite and back-toback relation, is disposed a list of the corresponding encoded indications, there being a window 14 for stroboscopically reading the terms while the disc rotates, and means also for reading the encoded indications, e.g. a bank of photoelectric cells. The terms and codes are present on strips 2 and 21 (Figs. 2a and 2b, not shown), fixed to the metal disc 1 by means of members passing through holes 6 (Figs. 2a and 2b, not shown), this also ensuring correct relative positioning of term and corresponding code strip. The length of the strip is equal to the pitch of the spiral. The disc 1 is mounted between the two arms of a U-shaped support 9, which is radially displaceable along bars 10 by engagement with a continuous chain 11. Windows (only one, 14, shown) permit observation of the term and code strips. The circumference of the sprocket 12 is equal to the pitch of the spiral, so that in one complete rotation of the disc, the window 14 in the support 9 moves from one coil of the spiral to the next. Observation of the terms may be achieved stroboscopically by shining a lamp 19 on to a mark 5 (Figs. 2a and 2b, not shown), e.g. of white paint, on each strip, and reading the reflected light intensity with a photo-electric cell 20 (Fig. 3a, not shown), the electronic apparatus 22 to 26 causing a synchronized flash from the tube 27, so permitting reading of each term at high speed. Instead of the mark 5, a hole 21 in each strip may be used (Fig. 3b, not shown). The keys 16 and 18 control the rotary motion of the disc, the speed being proportional to the displacement of the keys, this being achieved by means of a rack and pinion attached to a potentiometer incorporated in the motor supply (Fig. 4, not shown). As the speed of rotation decreases, a change from flashing to continuous light is effected by means of the circuit of Fig. 4. The code may be marked on the strip by photogravure, or by a magnetic recording technique, and closed circuit T.V. may be used for viewing.

The conveyor with the means for heating, cleaning and drying the tubes is the subject of Specification 1,240,305. Operation of the conveyor &c by piston-cylinder device (156) (Fig. 34, not shown) with an air supply controlled by master timer (272) continues until the last of the programmed tests is completed, when to end the cycle an end wash timer is actuated and this continues to index the conveyor for a predetermined number of cycles to ensure cleaning of all the tubes 24. The sample dispensing assembly (Fig. 7) comprises a pick-up needle (62) (Fig. 8, not shown) carried by car 64 movable along arm 66 which itself is rotatable about one end to move needle (62) to a position over a sample container 46 on turntable 32, which may be mounted over a cooling jacket 50, then back over a row of tubes 24 on the conveyor, car 64 travelling along arm 66 to dispense aliqnots of sample into each container in the row. The samples in each longitudinal row of tubes on the conveyor may be subjected to the same test. The sample pick-up and dispensing device is the subject of Specification 1,240,304. The reagent dispensing assembly (Fig. 35), which is the subject of Specification 1,240,306, comprises piston-cylinder device 280,278 and one-way valves 282, 284. Reagent is withdrawn from container 38 through valve 282 into the cylinder and forced out of the cylinder through valve 284 under air-pressure. The reagent dispensing lines for a row of tubes 24 on the conveyor pass through holes in a bar 334 mounted transversely over the conveyor. At the analysing station the contents of a row of tubes 24 are simultaneously aspirated into a row of cuvettes for optical measurement. The operations to be carried out on each sample are preselected by pressing buttons on a control panel (Figs. 1, 62, 64 not shown). The control means is the subject of Specification 1,240,308.
