Title: Universal open-end spinning method of multicomponent yarns production
IPC: D01H4/00
Filed: 1968-09-30
Abstract: In open end spinning of yarn the material supply of staple fibres is fed into a plurality of cavities formed at the nip of the rotating, peripherally grooved, drums 9, 10 where each groove 18 of one drum faces a corresponding groove 19 of the other drum, such that the material forms an open end, fibrous strand within each cavity, and then a twisting torque is applied to the strands to form spun yarn which is wound into a package 88. A polymer substrate may be extruded in the form of round filaments or flat strips into the cavities from extruder 2 and within the cavity mixes with the fibres. The grooves of the drums are perforated so as to be under the action of suction devices 24, 25 within the drum. Cutting rolls 14, 15 with cutters 40, 41 divide the incoming webs 12, 13 of loosely held together staple fibres into strips, providing one for each groove. The torque is imparted by any false twisting device 77, while the strand is continuously pulled downwardly by the wind up arrangement 11. To aid in the consolidation and formation of the yarn it may be passed through a narrowing groove 79 of a condensing, heated, member 82 and subsequently through the groove 81 of a cooled member 84. In an alternative embodiment (Fig. 2, not shown) the fibre supply arrangement consists of two aerodynamic fibre web forming devices. The surfaces of the drums may be cooled for yarn stabalization.

Patent ES-434627-A1 (ES)
Title: Charge-coupled device
IPC: H01L29/768
Filed: 1975-02-11
Abstract: The invention relates to a charge-coupled device in which the charge transport takes place in the form of majority charge carriers via the bulk of a surface layer of the first conductivity type which forms a p-n junction with a substrate of the second conductivity type. The comparatively thick and high-ohmic surface layer has a comparatively thin low-ohmic buried zone of the first conductivity type which adjoins the said p-n junction. The buried zone forms a buffer layer against the depletion zone belonging to the p-n junction. Without detrimentally influencing the transport properties, a low-ohmic substrate may be used, which has important advantages in particular with respect to the leakage currents.

Patent ES-437812-A1 (ES)
Title: Electrical measuring instrument having stationary coil-moving iron mechanism which operates on attraction principle
IPC: G01R5/14
Filed: 1975-05-20
Abstract: An instrument for measuring the magnitude of an electrical current. A coil, through which the current to be measured flows, is positioned between two spaced plates constructed of a magnetic material, with each plate having a generally spirally-shaped opening therein. U-shaped magnetic members are positioned to complete a magnetic circuit through the plates. A movable magnetic member extends substantially vertically between the openings of the plates, providing a magnetic path between the plates for magnetic flux flowing through the center of the coil. The movable member is mounted for restrained rotation within the openings of the plates, with the angular movement being responsive to the magnitude of the current flowing in the coil. The rotation of the movable member with increasing current reduces the distance between the movable member and the adjacent surfaces of the plates which define their generally spirally-shaped openings.

Filed: 1978-12-07
Abstract: The effluent gas stream from a partial oxidation gas generator is scrubbed with water. A dispersion of particulate carbon and water is produced, mixed with a liquid organic extractant, and separated in a decanter. The overhead stream from the decanter, comprising a dispersion of carbon in the liquid organic extractant, together with small amounts of water, is mixed with extraction oil and heated in a vaporizing operation to produce a vaporized overhead mixture, comprising substantially all of the water and liquid organic extractant, and an unvaporized liquid bottoms dispersion of carbon in extraction oil containing only a minor amount of water and liquid organic extractant. The bottoms dispersion is passed into a steam stripper in counterflow with stripping steam. The overhead from the steam stripper, in admixture with 0 to 100 volume % of the overhead from the vaporizing operation is cooled and condensed to separate water and liquid organic extractant by indirect heat exchange in at least two and preferably three separate heat exchange or condensing zones in series, with a different coolant in each zone. Liquid organic extractant and air or water are coolants in two of the zones and the coolant for any remaining zone is selected from the group: (a) at least a portion of carbon/liquid organic extractant/water dispersion overhead from the decanter, (b) at least a portion of the extraction oil, and (c) mixtures of (a) and (b). The bottoms stream from the steam stripper, comprising carbon and extraction oil may be mixed with hydrocarbonaceous feed and pumped into the gas generator with or without further heating.
