Title: Improvements in Baffle Plate Separators For Separating Particles from Gases
IPC: B01D45/06
Filed: 1967-06-01
Abstract: An air cleaner comprises an array of parallel corrugated baffles 2, defining tortuous passages along which the air flows therebetween, the rounded bends in the baffles becoming progressively sharper from upstream to downstream side. Fig. 2 shows baffles whose successive included angles [alpha] may be 100, 90 - and 80 degrees. In Fig. 3 (not shown), successive bends have decreasing radii of curvature of 20, 17 and 13 mm. In Fig. 4 (not shown), the planar sections of each baffle, upstream and downstream of the corrugations, are laterally staggered, and the downstream bend in each passage is displaced sideways of the others. There may be two to six bends in a passage. The cleaner is used in an air conditioning system downstream of a blower and a water spray humidifier (13) (Fig. 5, not shown), to remove the water droplets from the air.

Patent ES-351925-A1 (ES)
Title: A device operating as an altimeter and an altitude stabilizer
IPC: G01C5/06
Filed: 1968-03-23
Abstract: Apparatus for measurement and control of the altitude of an aircraft comprises first and second radiation sources and a radiation detector to detect the pressure of the atmospheric air, the detector being used in association with the first source when measurements of altitude are to be carried out, and with the second source when the output of the detector is to be used to control the altitude, the detector circuitry including a gate through which the detector output can be coupled to a servo mechanism, operating on the elevator or engine of the aircraft, when control of the altitude is to be undertaken. The radiation manometer comprises a chamber 1, through which atmospheric air can flow, containing a surface barrier diode of N-type silicon 2 mounted on a vertically displaceable arm 5. The two radiation sources are [alpha]-emitters, one 3 being of Am241, formed as an electrolytic deposit on a platinum disc, and the other 4 being a relatively thick disc of enriched uranium. They are mounted on a rotatable table which turns between two positions bringing either one of the sources in line with the detector 2. When source 3, which is effectively a monochromatic source, is operative the output of device 9, an integrator or ratemeter, operating on pulses from the detector which have passed through pre-amplifier 7 and threshold amplifier 8, is connected through gate 11 to operate a servo mechanism 12 controlling the aircraft elevator or engine, whereby a constant altitude may be maintained. When source 4, emitting a much wider range of energies, is operative the gate is closed, and the apparatus may function as an altimeter, the indicator 10 being graduated in altitudes. In altitude measurement, to obtain maximum sensitivity the threshold level of amplifier 8 is set as low as possible, by control C 3 , but high enough to suppress noise pulses. The sensitivity of the apparatus is affected by variation of the sourcedetector distance and several scales are provided on meter 10 corresponding to particular values of this distance. In altitude control, the threshold level is set to define the altitude to be kept. This is possible since, with the americium source, the pulse count rate is affected greatly by very slight altitude changes, up to a certain height, Fig.6 (not shown). The effective source-detector distance is adjusted when controlling altitude, for different altitude ranges by the introduction of respective filters for each range e.g. of polyester film or polyester film plus a gold filter. The apparatus is calibrated in a standard atmosphere and so corrections to the measured altitude are necessary to allow for air temperature variations with altitude.

A stop flange 28 may be provided for the face 15 to abut. The recess 7 may be lined with rubber or plastics material in a frame of metal or harder plastics than the lining. Single or double glazing may be mounted in the sash by removable glazing strips 23, Fig. 5 which has teeth 29 to be engaged by teeth 30 on tapered strip 28 which fixes sealing strips 31 against the glazing 21. The recess 6 in the sill of the main frame may be used to collect condensation water &c. from the window and which is drained away through tubes 17.
Patent ES-359738-A1 (ES)
Title: Process and apparatus for producing torque in synthetic filaments,fibers and yarns
IPC: D02G1/02
Filed: 1968-10-30
Abstract: Synthetic yarn is crimped by passing it along a path for a first time, returning the yarn to the path for a second time, twisting the lengths of yarn as they pass along the path and subsequently separating the yarn lengths. The yarn is drawn, heated and cooled during crimping. As shown, the yarn is passed twice in a twisted path between rods 11 and 16. The yarn lengths are twisted about each other in opposite directions on either side of twisting pin 18, which inserts false twist into the yarn. At the start of operation the yarn lengths pass on either side of pin 18 and the spindle 10 is then rotated manually to insert the required number of turns of twist in the yarn lengths. The yarn can be heated prior to twisting. The yarn can be drawn prior to twisting or after the yarn has passed along the twisting path for a first time, see Figs. 1 and 2, not shown.
