Title: Method of opening crimped yarn
IPC: D02G1/00
Filed: 1968-08-12
Abstract: A knit-set-deknit crimped yarn is opened by withdrawing the yarn from a knitted fabric 1, passing through a relaxation zone 5 under a tension of less than 0.05 g/d and thereafter applying a frictional force to the yarn in its relaxed state to displace the filaments relative to one another thereby to open the yarn. The relaxation zone extends between a roller 4 for withdrawing the yarn from the fabric and the device 6 for applying the frictional force to the fabric. The peripheral speed of the withdrawal roller 4 is higher than that of the yarn to cause the roller to slip with respect to the yarn. As shown, the device 6 comprises an agate knife edge 7. Alternatively, the device 6 can comprise two parts resiliently pressed together or an aerofoil-shaped ceramic pin. After passing the friction device 6 the yarn can be advanced at a tension of at least 0.1 g/d. The yarn can be entangled and interlaced by a fluid. This treatment may decrease the bulkiness of the yarn.

Title: Fluid control system for liquid storage apparatus
IPC: F17C13/12
Filed: 1968-08-17
Abstract: L.N.G. is stored under pressure and near its boiling point in a heat-insulated vessel 20a having no ullage space and vapour evolved due to heat leak together with expanded liquid is vented through a duct 34 leading to a drum 38 of sufficient capacity to accommodate said vented vapour and liquid and having sufficient ullage space to provide for expansion and vaporization due to normal heat leak in the drum itself which latter has a pressure relief vent valve 61 in a discharge stack 62. A plurality of vessels 20a to 20n are vertically mounted in a ship's hold and have access ducts 21a to 21n connected by relief valve 36a to 36n to the vent duct 34 and by liquid block valves 27a to 27n to an insulated liquid header 26 having one end leading to the drum 38 and the opposite end connectable to a shore liquidfill and emptying line 11 and a pump 12 to a tank 10. The storage vessels have further access ducts 22a connected by relief valves 35a to 35n to vent duct 34 and by block valves 31a to a main uninsulated vapour header 30 connected at one end to drum 38 and connectable at the other end to a shore line 13 and a compressor 14 to the vapour space of tank 10. Vapour block valves 31a-31n are each controlled by a liquid sensor 32a to 32n whilst the liquid block valves 27a to 27n are controlled by vapour sensors 28a to 28n. The liquid level in drum 38 is maintained below a predetermined height by means 49 which withdraws excess liquid, vaporizes it and discharges either through valve 61 and stack 62 or through a line 55 to the ship's engines or to a burner 59. To fill the vessels 20a-20n and with shore lines 11, 13 connected to headers 26, 30 a valve 48 in header 26 is closed, valves 23a to 23n and open as are valves 15, 16, 29, 33 and pump 12 is operated and liquid flows through open liquid block valves 27a to 27n to the vessels 20a to 20n whilst vapour is forced through open valves 31a to 31n, header 30 and line 13 to tank 10. When a given vessel, say 20a, is filled with liquid, the level reaches a sensor 32a which then closes the liquid block valve 27a, which it controls, and filling is completed when sensor 32n closes valve 27n. During the voyage valves 23a to 23n and 27a to 27n are closed but valve 48 and vapour block valves 31a to 31n remain open whereby expansion liquid in access ducts 22a to 22n gains access to the uninsulated header 30 where it is vaporized and carried through the vent header to the drum 38.

Patent ES-378912-A1 (ES)
Title: Key telephone systems using pushbutton or rotary dials
IPC: H04M9/00
Filed: 1970-04-22
Abstract: An intercommunication system has subscriber stations 50 connected to a plurality of exchange lines 51 and to a single common intercom line 52 and these connections are selected by operation of respective keys. The called party on the intercom line is selected by operating a dial or push-buttons. The solution equipment thus has to accept either open-circuit pulses or multifrequency tones. In both forms of signalling the number of the called party is finally stored in binary form on relays in the binary digit store 58 and causes the respective relay contacts in trees 59, 60 to be operated to supply a calling signal, both ringing and a flashing lamp, to the required station. Tone frequency signals on a two out of seven code are detected in filters 55 and pass to binary converter 57 which consists of AND gates whose outputs energize the respective relays in store 58. Dial pulses are detected as the opening of a relay contact in detector 64 and are then repeated as short duration standard height pulses which are used in converter 65. Use of the actual dial pulses could cause erroneous operation of the relays in store 58. Each pulse received causes the respective ones of the binary relays to be energized so that the energization pattern indicates the number of pulses received and causes contact trees 59, 60 to be set so that the required station is signalled. The control unit provides the signalling and other call signals and includes a circuit 62 which detects either one or two stations to be off hook and alters the output of the signalling control accordingly. Call signalling includes providing a steady light at all stations to indicate that the common line 52 is seized and the provision of both a flashing light and single or repeated ringing signal at the called station. When the called station goes off hook the light stops flashing and burns steadily.

Title: Device for locating defective fuel
IPC: G21C17/07
Filed: 1976-06-07
Abstract: A method and apparatus for locating defective nuclear fuel elements is disclosed. Fuel elements that are to be tested are enclosed in a test chamber, filled with water. Air is pumped or pulled into the chamber, entering through a gas sparger at the bottom of the chamber and displacing a portion of the water above the fuel element. This reduces the pressure in the vessel, forms an air pocket above the fuel element and purges the water surrounding the fuel element of fission gases released from defective fuel elements. The activity of sample gas drawn from the chamber is continuously monitored to indicate fission gas content. In subsequent steps the pressure in the chamber is further reduced with a vacuum pump and gas drawn from the air pocket above the fuel for testing is recirculated and allowed to continuously purge the water surrounding the fuel elements of fission gases released from defective fuel elements.

Title: Apparatus for applying a protective coating to the welded seam of a can body or the like
IPC: B05C13/02
Filed: 1978-05-12
Abstract: An apparatus for applying a protective coating to the inside of the welded seam of cans. When fabricating cans which are provided at their inner surface with a protective coating it is necessary, following the welding operation, to apply to the region of the welding seam the then missing part of the protective coating. Prior techniques were unable to achieve any optimum application of the seam-coating which would reliably cover the welded seam. If the fabricated cans are particularly intended for use for canned foods this then is dangerous to the health of the user. With the apparatus of the invention the protective coating is applied by means of a driven applicator roll to the welded seam. By suitably selecting the outer or jacket surface of the roll and a scraper as well as the rotational speed of the roll it is possible to optimize application of the protective coating.

Title: Tachometer system
IPC: G01P3/42
Filed: 1979-01-08
Abstract: A tachometer system for supplying a control signal indicative of positional and/or speed errors of a rotatable element comprises a tachometer on which marks are arranged in a closed track and a detector responsive thereto to produce n tacho-pulses per revolution of the tachometer. The tachometer system further comprises a memory device with n locations in which n correction signals are stored. The correction signals are obtained by driving the tachometer at an accurately constant speed, measuring the phase difference between the tacho-pulses and the reference signal, and storing the phase-error signals related to the consecutive tacho-pulses in separate locations of the memory device. When the tachometer system is used in a servo control loop these correction signals are used to correct the phase-error signals then measured, yielding a correction in respect of the deviations in these phase-error signals owing to positional tolerances of the marks on the tachometer.
