Patent ES-302682-A1 (ES)
Title: Method for producing yarn
IPC: D02G3/32
Filed: 1964-07-31
Abstract: In a process of forming a composite elastic core yarn from an elastomeric - for example spandex - yarn 11 and from one or more rovings 49, by feeding yarn 11 to the front drafting rolls 42, 43 of a spinning frame, the yarn 11 is passed around a wheel 25 to which is applied a constant magnetic drag thereby to impart a constant elongation to the yarn as it reaches rolls 42, 43. Wheel 25, of nylon and having a hysteresis ring, is rotatably mounted on a bolt. Cylindrical magnets, adjustably spaced on the bolt from the ring, cause a braking force on the wheel, the magnitude of which is independent of the speed of revolution of the wheel. Adjacent the drafting rolls, yarn 11 is guided by a wire finger 26 rigidly secured to bar 30 which is slowly traversed and which also supports trumpet guides for the rovings. The yarn path from bobbin 12 to rolls 42, 43 is preferably at least 30" long. Yarn 11 is twisted when unwound from bobbin 12 and backtwisted when wound on bobbin 59. To reduce the liveliness of the composite yarn it is subjected to a vacuum, steam is introduced therein, and then the vacuum is restored to remove excess moisture from the yarn. The rovings may be composed of wool, cotton, nylon, polyacrylonitrile, polyester, -or rayon fibres, and blends thereof.

Title: Semiconductor device
IPC: H01L27/06
Filed: 1967-03-01
Abstract: In a semi-conductor arrangement, two surface regions of the same conductivity type and doping concentration and covered with oxide layers are given different electrical properties by providing the overlying oxide layers with different properties. The different electrical properties are achieved by forming the oxide on one of the regions so that it produces an inversion layer in the surface of the region. In a first embodiment, Fig. 1 (not shown), two identical insulated gate FET's are formed in a semi-conductor body by diffusing in the source and drain regions and applying a gate electrode over the insulating layer, the gate insulation of one of the transistors having been treated so that an inversion layer is formed between the source and drain. The untreated device operates in the enhancement mode with zero drain current at zero gate bias while the treated device has an appreciable drain current at zero gate voltage and so can be used in either the depletion or the enhancement mode. In a second embodiment, Fig. 3 (not shown), a bipolar transistor and an FET are manufactured by diffusing two regions into a wafer and then diffusing a region of the opposite type into one of the first regions to form the bipolar transistor and simultaneously diffusing two regions of the opposite type into the other of the first regions to form the source and drain of the FET. The oxide covering the channel of the FET is then treated to form an inversion layer. The invention may be applied to other combinations of semi-conductor devices in which an inversion layer is required over certain areas, the combination of a transistor and a thyristor being mentioned. The devices may be produced by polishing a P-type silicon wafer doped with indium, etching the surface and thermally oxidizing in moist oxygen. The oxide is photomasked and etched to form windows into which phosphorous is diffused by heating in nitrogen containing phosphorous pentoxide and then heating to drive-in the phosphorous. Methods of treating the silicon dioxide layer to produce selectively the inversion layer are described and include locally removing the phosphorous-containing surface of the oxide layer, produced during the diffusion locally depositing silicon monoxide, by evaporation in vacuo, on the silicon dioxide layer and heating in dry oxygen irradiating with X-rays and U.V. radiation replacing part of the oxide masking layer with an oxide layer produced by heating in oxygen saturated with steam heating in hydrogen locally depositing a metal (e.g. aluminium) on the oxide, heating, and then removing the metal removing the oxide and selectively depositing different oxides such as silicon oxide and lead oxide or silicon oxide and aluminium oxide applying a temperature gradient between the faces of the wafer and heating locally using I.R. radiation. The invention may be applied to devices made from germanium and to bodies comprising layers of semi-conductor material on an insulating substrate.

Title: Cooling apparatus and process
IPC: B01D51/10
Filed: 1967-04-17
Abstract: In a fluid cooling process, intended for the cooling of hot gases from the hydrocarbon cracking process described in Specification 1,165,906, the fluid is cooled in an annular chamber which at the inlet end thereof increases in cross-sectional area per unit length such that the outlet pressure of said fluid is substantially the same as the inlet pressure to said chamber. Preferably the area increase is equal to the increase in cross-sectional area of a conical pipe having an angle of divergence of from 4 to 7 degrees. In the gas cooling process described, the hot gases at from 1350 to 1650 F. are introduced into the annular chamber at about 700 to 800 feet/sec. and are cooled therein in about 1 to 30 milliseconds to about 1200 to 1400 F. The gas cooler shown comprises concentric tubes defining an annular coolant passage 33 arranged within an annular passage 35 for the gas to be cooled. This latter passage includes conical members 38, 39 at the gas inlet end 40 of the passage, together providing the required change in cross-sectional area at the passage inlet. The cooled gas is discharged through an outlet 44. Coolant (e.g. water) enters at 73 and is discharged (e.g. as steam) at 75. Other coolant means may as shown comprise spaced-apart tubes 67 arranged around the gas passage 35 and in close contact with the outer wallsurface thereof. The tubes extend between coolant inlet and outlet annular headers 49, 50 and the spaces between adjacent tubes (see Fig. 2) are filled with a heat conducting material (unspecified). Fins (56, Fig. 4), may extend into the gas passage 35 from the wall 34.

Title: A method and apparatus for manufacturing a bellows-like structure
IPC: B29C53/04
Filed: 1967-11-17
Abstract: A bellows structure of water proof impregnated fabric of heat fixable material is made by placing the fabric in intended folds, maintaining the fabric under pressure in this position and subjecting the fabric to heat treatment at a sufficient temperature and for a sufficient period of time to permanently fix the fabric. The structure is intended to be attached to the upper surface of a vehicle, e.g. a tank or armoured car, and can be drawn up to extend above the vehicle to allow it to float in water. The fabric is made of nylon, polyethylene terephthalate or polyacrylonitrile and is made water proof by impregnation with natural or synthetic rubber. The fabric is sewn to the required shape of the structure, i.e. rectangular with chamfered corners, and the intended fold lines are drawn thereon. The structure is suspended from a frame-like carrier 1, Fig. 3, to hang loosely over a template 2 which comprises a frame 3, Fig. 9, having inner and outer posts 4, 5 which project upwards to a height greater than the height of the collapsed bellows structure. The bottom edge of the fabric is secured by temporary clamps 6, Figs. 3 and 4, which engage around the frame 3. Each clamp 6, Fig. 4, comprises a rod 11, a stationary plate 12 and a movable plate 13 provided with a resilient stirrup 14 through which the rod 11 passes. If desired, the outer folds are prefixed by securing clamps 1 thereto and then applying heated tongs (7a), Fig. 1 (not shown), at a temperature of 100 C., for example. The structure is positioned in the template in the form shown in Fig. 9 with the prefixed outer folds against the posts 5 with members 8, slidable on the posts 5, positioned between adjacent folds. On the opposite side, members 9 rest against the posts 4 and are provided with plates 10 which extend internally of the prefixed folds. Displacement of the fabric is prevented by positioning U- shaped clamps 15 around the folds. When the complete structure has been folded in the template, cover plates 16 are placed thereover. Clamps (17), Fig. 5 (not shown), are applied to compress the fabric between the plates 16 and the frame 3. Each clamp (17) comprises belts 18, 19, Fig. 9, and cross-pieces 20, 21. The clamps 6, 15 are removed and the template 2 is introduced into an oven, e.g. at 100-200 C. for -2 hours, to permanently fix the folds of the bellows structure.
