Filed: 1930-07-14
Abstract: 352,740. Vinegar. ERINGS, H., 39, Meckenheimer Allee, Bonn-am-Rhine, Germany. July 14, 1930, No. 21300. Convention date, May 6. [Class 14 (ii).] Vinegar is made by a continuous circulation process, the rate and temperature o infusion being co-ordinated, pre ferably auto matically, in such a manner that the temperature in individual zones of the gene. rator filling remains constant at an optimum value. Alcoholic liquid is drawn by a pump 9 from the collecting space 3 and forced through a flow-control valve 11 into a cooler 12. The cooled mash passes through a pipe 15 into a sparger wheel 16 in the upper part of the vinegar generator 1 and flows down the filling 4. The regulator 18 controls the infusion temperature through an operative connection upon a valve 19 in the cooling water pipe 13. The regulator 20 controls the rate of infusion through a valve 21 in the mash pipe. An areometer or hydrometer 22 causes a signal to function when acetification is complete. The sparger wheel 16 has a siphon 17 so that only one arm 16<1> is in use unless the flow of liquid exceeds a certain limit.

IPC: D02G1/16
Filed: 1960-06-17
Abstract: 952,464. Bulking yarns. EASTMAN KODAK CO. June 17,1960, No. 21306/60. Heading DIF. A travelling multifilament yarn e.g. of cellulose acetate, is bulked at a bulking station whereat it is subjected to the action of warm air (at a temperature of at least 90‹F.) which is free from condensate. The air may be filtered e.g. in three successive stages, to remove contaminants such as lint or oil of particle size greater than two microns. Two or more yarn ends may be bulked in one or each jet at the station and bulking may be enhanced by feed the yarn to the jet at a faster rate than the bulked yarn is withdrawn therefrom. It is recommended that the relative humidity for compressed air supplied to bulking jets should not exceed 30% for supply pressures up to 25 p.s.i.g. In the apparatus shown, air passes through a prefilter 1, an absolute filter 2, a compressor 3, a heater 4 and a filter 5 so as to supply clean dry air through a conduct 31 and inlet pipe 32 to a jet 6 which is enclosed in a removable or openable shroud 7, Figs. 2 and 3 and Fig. 4 (not shown) so that spent air from the jet can be conducted through a flexible tube 8 into an exhaust header 9 coupled to an exhaust fan 10 (see Specification 952, 466). Yarn fed from a package 33 by a feed roller 34 enters the jet at 35 and the bulked yarn is withdrawn at 26 by a roller 37 and taken-up as a package on a spindle 38. The cleaning action of the filters 1, 2 and 5 may be augmented by electrostatic precipitation (not shown). The noise produced by the jet is muffled (see Specification 952, 465).
