Title: Method for treating textile materials to uniformly set their shape
IPC: D02G1/20
Filed: 1968-02-23
Abstract: In the treatment of a web of textile fabric formed of synthetic fibres, e.g. polyester, polyamide, polyacrylic, polypropylene or cellulose triacetate fibres, which have been textured at a predetermined temperature, in which the texture of the filaments is reset at a higher temperature and the interlacing loops and off sets of the fabric are also set so that they exhibit elastic memory at this higher temperature, the fabric web supported in an open condition is immersed in a bath of liquid maintained at a substantially constant temperature which is higher than the predetermined temperature at which the fibres were originally textured but below the glass transition temperature of the fibres so that the fibres in the web are heated to substantially the temperature of the liquid, and the web is removed from the bath and cooled to set the texture of the fibres and the interlacing loops and offsets of the fabric. The fabric web may be supported on a conveyor which may be formed by a tenter frame which employs pins or clips to support the fabric web at a controlled width between a pair of rails moving at a constant speed, and which carries the web in a longitudinal direction through the bath, shrinkage in both the longitudinal and transverse directions being allowed by overfeeding the fabric web onto the conveyor arid by adjusting the width of the conveyor in the region of the bath to allow for transverse shrinkage if the fabric web has not been preshrunk. The fabric web may be immersed in the treating liquid at 300 -450 F for 1-15 seconds and the liquid may flow with the fabric web in the bath at a velocity substantially equal to or lesser or greater than the velocity of the web. The fabric may be cooled by passing it through a cooling and washing bath and then dried or treated with a dye, antistatic agent or UV absorber. The texture of the fabric may be altered by controlling the tension of the web by controlling the rate of feed and width of the web or by controlling the rate of flow and direction of the treating liquid in the bath. The treating liquid may be a polyhydric alcohol, e.g. ethylene, diethylene, triethylene, tetraethylene, propylene or dipropylene glycol, an alkylene carbonate, e.g. ethylene, diethylene, propylene or dipropylene carbonate, or a mixture thereof, or a mixture of a polyhydric alcohol and diglycollic acid or phosphoric acid. In Fig. 1 fabric web is unwound from roll 10, passed through feeding mechanism 12 and mounted on pins 14 of tenter chain 16 modified so that an offset 18 is provided in which the fabric web is carried through heated liquid 20 in trough 22 provided with a pipe 24 having inlet 26 and outlet 28 and a pump for circulating the treating liquid in the direction of the fabric web. The fabric web is then passed through washing bath 30 maintained at a temperature lower than the temperature of the treating liquid and dried.

Title: Improvements in the manufacture of synthetic textile yarns for hosiery
IPC: D02G3/26
Filed: 1969-07-02
Abstract: A process for the manufacture of a yarn which can be used particularly for hosiery, wherein the yarn is subjected to twisting and untwisting operations, is characterised in that a synthetic material yarn is first twisted to a value ranging between one third and one quarter of its saturating twist, this twist is then fixed and the yarn is then partially untwisted leaving a final twist with the same direction as the initial twist which was imparted and ranging between 0.1 and 0.3 times the value of that initial twist. The initial twist is preferably fixed in the presence of saturated steam in a non- oxidising atmosphere, and is effected by a treatment including a slow rise in temperature, a stage at the maximum temperature, rapid cooling followed by a rapid rise in temperature and finally cooling to room temperature. The thermal treatment may be repeated several times. The yarn may be given an initial S- or Z-twist and two yarns may be doubled for use.

Title: Fuel oil filter
IPC: B01D29/01
Filed: 1978-04-21
Abstract: A totally enclosed fuel oil filter housing having a fuel inlet nipple and a fuel outlet nipple is assembled on a mounting bracket with the nipples extending through hexagonal apertures in the mounting bracket. The inlet and outlet nipples are threaded to couple connecting fuel lines and are of different sizes to prevent a reversal of the connections. The nipples have hexagonal peripheries which mate the apertures so that torsional forces during coupling are transmitted to the bracket rather than to the seals between the nipples and the filter housing, and the apertures of the mounting bracket are formed by being drawn out of the plane of the base of the mounting bracket to project therefrom. The side walls of the housing has inwardly directed ribs and a bead of sealant spans each rib to localize the pressure between the side walls of the housing and the accordion pleated filter medium through the sealant bead to assure a void-free seal therebetween.

Patent ES-480760-A1 (ES)
Title: Method and apparatus for recovery of energy from blast furnace exhaust gas
IPC: F01K7/34
Filed: 1979-05-21
Abstract: The present invention relates to a method and apparatus for recovering energy from a blast furnace exhaust gas by utilizing an axial-flow turbine. According to the method of the present invention, a blast furnace exhaust gas is first passed through a wet scrubber to remove dusts and form a saturated gas, and low temperature water is sprayed to the saturated gas to add condensed mists to the gas. According to this method, adhesion of dusts to a turbine can be effectively prevented. When large nozzles and large moving blades are used for the turbine for use in practising this method, adhesion of dusts and erosion of nozzles and moving blades can be effectively prevented. This energy recovery method can be practised very advantageously by using an axial-flow turbine in which the gas flow-out direction at the nozzle outlet is made in agreement with the gas flow-out direction at the moving blade outlet to always impart to the gas a swirling speed around the axial center of the turbine, so that the dusts and mists are shaken off from the gas.

Patent ES-8100484-A1 (ES)
Title: Method and apparatus for detecting blemishes on the surface of an article
IPC: G01B11/30
Filed: 1980-02-15
Abstract: A method and apparatus for grading and sorting articles, particularly fruit, according to size, surface blemish and surface color. Fruit is passed sequentially through a camera array which scans the surface of each fruit and measures the intensity of light reflected from successive discrete surface segments. Significant differences between such measured intensities are detected and a measurement of surface blemish is generated in accordance therewith. Size measurements are derived by counting the total number of segments in the surface of each fruit. Color measurements are derived by averaging the ratio of red light intensity to infrared light intensity reflected from each of a plurality of surface areas of each fruit. The fruit are separated and delivered to separate receivers by a mechanism responsive to the size, blemish and color measurements of the respective fruit.
