Patent EP-0398126-A1 (EP)
Inventor: YAMAKITA YOSHIMICHI
IPC: D06B23/30
Filed: 1990-05-08
Abstract: A method of continuous changing dye-colour in spray dyeing for a long tape, which is fed by guides continuously. According to a preferred embodiment, one dye-solution is sprayed for the tape from at least one dyeing-nozzle connected to one feeding line, which is either of a pair of feeding lines and which feeds selectively the one dye-solution or one cleaning-solution. When the tape is fed with a predetermined length, the spraying of the one dye-solution is stopped. Then, the one dyeing-nozzle is exchanged with at least one other dyeing-nozzle by turning the one dyeing-­nozzle away from the tape and turning the other dyeing-nozzle to the tape for spraying another dye-solution. While the other dye-­solution is sprayed, the one dyeing-nozzle, which was used for spraying for a proceeding sprayed portion of the tape, and the one feeding line, to which the one dyeing-nozzle is connected, are cleaned with the one cleaning-solution to prepare for spraying a new dye-solution. Further, at just on time when an undyed portion, which is produced by the exchanging of the dyeing-nozzles, passes through each guide, the dye-solution attached to each guide is removed so as not to mix into a following sprayed portion of the tape.

Abstract: In a pelleting machine having a rotating die disc (2), in order to monitor the maximum pressing forces the forces exerted by the rams (4) are transmitted for evaluation to a computer, by means of which an ejector device (10) is to be controlled so that defective pellets can be separated out. Since a pellet press makes use of die discs having a varying number of die bores and therefore also different numbers of rams, in known devices a complete changeover, for instance of the proximity switches, to the particular ram division is necessary. According to the invention, the exchange of a die disc (2) for one of a different kind is substantially simplified by the avoidance of a changeover of the electronic device, if the position of the die disc (2) is determined continuously by the emission of pulses from an angular pulse transmitter (20) connected to a computer (26, 34), in which the pulses are coordinated with entered maximum pressing-force values for the purpose of evaluation. For this, the pellet press is equipped with an angular pulse transmitter (20) which transmits the pulses triggered by the rotating die disc (2) to a connected computer for allocation to the measured maximum pressing forces. The signal transmitter (18) can at the same time be designed as a disc which is provided with a coding and which is arranged preferably exchangeably and adjustably.

Abstract: A sewing machine pressing leg and an adjusting device therefor is disclosed, wherein several rollers are disposed under the pressing leg to contact a sewed material so as to censure the smoothness of material feeding and avoid crimp of the sewed material. Therefore, the seam is kept straight, smooth and beautiful. The contact area between such pressing leg and sewed material is larger so that a smaller pressure is applied to acquire better material pressing effect so as to avoid a pressing track left on the surface of the sewed material by the rollers. The pressing leg is mounted on a transverse and a longitudinal adjusting bar by means of which the pressing leg can be adjusted to an optimum position to press the sewed material and facilitate the sewing operation.

Date Feb. 21, 1991.Separation of tetrahydrofuran (THF) from a mixture containing water, THF and a lower alkanol such as ethanol or methanol, is achieved by distillation in two zones, the vaporous mixture from the first zone being condensed and redistilled at a higher pressure in the second zone. Substantially pure THF is recovered from a lower part of the second zone, while the vapor from the top of the second zone is combined with the vapor from the first zone prior to condensation and the resulting condensate forms the liquid feed to the second zone. The process is suitable for recovering THF from complex reaction mixtures, containing also butane-1,4-diol and gamma-butyrolactone, obtained by hydrogenation of a dialkyl maleate.

Abstract: A parison thickness control system includes an extruder die (1) and a mandrel (2) which are movable relative to each other to change wall thickness of a parison (4) extruded between the extruder die (1) and the mandrel (2) during an extrusion or forming cycle of the parison. A parison control pattern is derived by manually inputting master points each defined in terms of a target parison wall thickness and an elapsed time during the parison extrusion cycle. A further parison control pattern is derived by performing the spline interpolation to interpolate between the master points. A still further parison control pattern is derived by correcting the above-noted further parison control pattern to allow the maximum or minimum value of the master points to indicate a limit value for the target parison wall thickness during the parison extrusion cycle. The parison extrusion cycle is divided into a given number of equal time intervals to define cycle points. The target parison wall thickness is derived for each cycle point based on the above-noted still further parison control pattern. The relative movement between the extruder die (1) and the mandrel (2) is controlled based on the derived target parison wall thickness for each cycle point. At least one of the cycle points may be used for triggering operation of an associated device.
