Patent ES-358389-A1 (ES)
Title: Creel
IPC: B65H63/036
Filed: 1968-09-21
Abstract: Bobbins 6 are mounted for rotation by placing them in dishes 8 on spindles 10. An inflatable tube 14 surmounted by a strip 21 of braking material extends under all the dishes 8 in each row on the creel. The tubes are normally deflated, but when the warper that is drawing the yarns from the bobbin is stopped (e.g. by a yarn breakage detector) the tubes are inflated to bring the bobbins to rest. The air supply system may include a pressure-operated switch acting if the air supply fails, so as to stop the machine whilst there is still sufficient air in an accumulator to inflate the braking tubes. Conversely, the inflatable tubes may lie under the ends of the spindles and may be normally inflated to lift the dishes 8 off the braking strip 8.

The catalyst may be an oxide, cerate, manganate, manganite, chromite, chromate or vanadate of cobalt, nickel, ruthenium, palladium, platinum or a rare earth metal or a mixture of rare earth oxides. The wetting agent used may be glycerol or another polyol or any detergent that does not prevent the formation of the high temperature binder or the catalytic action. The high temperature binder may be titanium dioxide, formed from titanium lactate added to the slurry, or silicon dioxide formed from sodium silicate in the slurry. The water used to form the slurry is distilled or de-ionized, and the slurry is applied by an airless method. The ratio of active catalyst to high temperature binder in the finished coating is between 45:1 and 70:1 by weight.
Patent ES-377960-A1 (ES)
Title: Method and apparatus for simultaneously recording on film time displaced segments of an electrical signal
IPC: H04N9/79
Filed: 1970-03-25
Abstract: Video signals from pairs of successive fields produced by a television camera 10a are recorded on black and white cinematograph film in interlaced relationship in a single film frame. To shorten the number of film frames needed to record a program of a plurality of pairs of interlaced television fields the signals are passed through a one-field period delay means 18, and the delayed and non-delayed luminance signals are alternatively sampled at 27 at a frequency high relative to a line period whilst the spot producing the raster on the printing cathode-ray tube 28, Fig. 1, is subjected during the display to a castellated line scan, Fig. 2A, of said sampling frequency, such that the successive luminance fields are laid down in a dot-interlaced manner, e.g. field 1 on line portions 39 and 42 and field 2 on line portions 41 and 43. Vertical sync. pulses control the continuous film drive. To ensure that the delay of the delayed video signal is exactly one-field period, a small variable delay 19 is used, servo controlled by the output of a phase detector 22 determining the phase difference between sync. signals from the delayed and non-delayed video signals. The high frequency sampling signal is produced by generator 27a and is also added at 34 to the vertical deflectors signal from the tube 28. As an alternative to the above sequential sampling with a single beam, a recording beam tube 281, Fig. 3, using two beams may be used, beam 1 recording lines 39a, 42a, Fig. 2B, from the delayed first field of a pair and beam 2 recording interlaced lines 41a, 43a1 from the second field of the pair. Continuous film movement is again used, and each field is recorded twice in consecutive film frames. In the arrangement of Fig. 4 a twobeam tube 2 is again used. Delays 62 and 64 delay the successive fields A 1 , B 1 , A 2 , B 2 , A 3 , B 3 &c. for one and two-field periods respectively. A gate 66 passes the undelayed field signals, and the two-field period delayed signals on successive fields under the control of sync. generator 16. Beam 1 is modulated with the output of the gate 66 and beam 2 with the output of delay 62. The action of the circuit may be summarized by the following table:

Title: Device for packing objects in a bag
IPC: B65B67/12
Filed: 1972-09-04
Abstract: The invention provides an improved device for packing objects in a bag, in which the objects are pushed through a sleeve to come into a bag that is suspended below said sleeve.
