Patent ES-303547-A1 (ES)
Title: Echo sounder
IPC: B02C19/00
Filed: 1964-08-28
Abstract: In a pulse echo-sounder for depth-recording or fish location, the echo period is measured by gating a clock-pulse counter on with the transmitted pulse and off with the echo pulse, the counter feeding a digital display with a stored read-out in terms of distance. In the embodiment of Fig. 2, ultrasonic transmitter (2) drives a magnetostrictive transmitting-receiving transducer (4) and echo pulses are amplified by an amplifier (3) (these may form part of a known system). In a unit (5), pulses from transmitter (2) and amplifier (3) are shaped and used to open a gate (7) to feed clock pulses from a generator (6) to a binary counter (8) during the echo period. A bank of relays (9) converts the binary count to a three-figure decimal reading which is displayed on digital indicator lamps in a unit (10) and in slave read-out units (11), and which is printed out on paper tape by a printer (12). The frequency of the clock pulses from generator (6) may have one of four predetermined values in the range 390 c/s. to 7500 c/s. to give a depth reading in decimetres, metres, feet or fathoms, the particular unit of measurement being displayed. In order to prevent flicker of the read-out the relays in the bank (9) are provided with hold-in contacts and store the read-out information until deenergized simultaneously by a control circuit (13). A timing unit (15) determines the rate at which echo sounding measurements in display (10) are changed and a recording device (16) may be used to provide a conventional echo gram.

Title: Polypivalolactone yarn
IPC: D02G3/02
Filed: 1968-08-19
Abstract: Polypivalolactone filaments having a tenacity of at: least 7 g/den and an elongation at break of not more than 20% may be produced by melt-spinning polypivalolactone having an intrinsic viscosity of not less than 0À75 (measured in trifluoroacetic acid at 25 C.), preferably between 2 and 4, through a spinneret having orifices of at least 0À2 mm. diameter, but in particular having orifices of 0À7 to 2À5 mm. diameter, preferably of 1À0 to 1À5 mm. diameter while applying drawdown at a ratio of 50 to 500, preferably of 100 to 300. It is essential that the extruded filaments after having been drawn down, are quenched, i.e. shock-cooled, by means of a liquid medium having a temperature below 100 C. The solidified filaments (usually formed into a yarn before or after the quenching step by passing them through a convergence guide) are then annealed at a temperature between 110 and 220 C., preferably between 140 and 180 C., without applying stretch. The annealing time is usually at least 1/ 10 th of a second, e.g. 3-120 minutes, in particular 10 to 30 minutes. The filaments may be allowed to shrink freely or to a certain extent, but are advantageously kept at constant length during annealing. Lastly, the filaments are stretched to 65-95%, preferably to 70-85%, of the elongation at break of the annealed filaments. Thus, if the filaments possess an elongation of 70% (i.e. the filaments or yarn will break when stretched to 1À7 times its original length) it will, upon stretching at a draw ratio of 1À6 : 1, provide a yarn stretched to 85% of the elongation at break of the annealed yarn. Suitable stretch ratios are in the range of 1À1 : 1 to 2 : 1, preferably of 1À4 : 1 to 1À75 : 1. Stretching may be carried out at a temperature from room temperature up to 210 C. but is preferably effected at temperatures between 150 and 200 C. The stretched yarn is subsequently wound up. on known means. The term " polypivalolactone " is defined as a linear polyester consisting essentially of recurring ester structural units having the formula The application of draw down to the. extruded. filaments may be applied to them while they are passing through a zone, e.g., a " hot box" situated immediately next to the spinneret and.. maintained at a temperature between 175 and 305 C., in particular between 250 and 300 C. and in which the diameter of the filaments is reduced to a diameter of between 1/ 7 and 1/ 20 . of the diameter at which. the filaments. are. extruded. The " hot box " may have a length of 10 to 30 cm. and the quenching zone is preferably not more than 35 cm. below the. hot box.

Patent ES-363306-A1 (ES)
Title: Solid state carbonator control
IPC: G05D9/12
Filed: 1969-02-05
Abstract: Two electrodes contacted by different degrees of accumulation of a substance within a container are associated with solid state switching devices so connected that means regulating the accumulation of the substance are energized or de-energized according to whether the substance makes or breaks contact with both electrodes. In Fig.1, a pump 17, energized from an A.C. source 11 through a triac 13, supplies liquid to a container 36. When the liquid touches both electrodes 37 and 38, transistors 42 and 43 are both rendered non-conductive to de-energize a relay 66 and open contact 19 so that triac 13 is rendered non-conductive to switch off pump 17. When the level falls below electrode 38 and transistor 43 becomes conductive, the current taken by the latter is insufficient to operate relay 66 and restart pump 17 until the level falls below electrode 37 and the current is increased by transistor 42. Then, when the level rises and transistor 42 is again non-conductive, the current taken by transistor 43 is sufficient to maintain relay 66 and pump 17 operating until the level reaches electrode 38. A similar system is described for controlling a compressor to maintain the thickness of an ice bank between limits determined by a pair of electrodes.
