Fabric and filamentary materials, e.g. woven, non-woven and knitted textile fabrics 4 warp threads, are washed by winding the material on to the perforated surface of a drum 5 rotatable about its longitudinal axis, periodically introducing charges of washing liquid into the interior of the drum, and rapidly rotating the drum whereby washing liquid is forced from the interior of the drum into the wound material and, during the intervals between the introduction of the charges of the washing liquid into the interior of the drum, at least part of the washing liquid in the wound material is forced out therefrom by centrifugal force, the material thereby being subjected to a plurality of washing treatments with separate charges of washing liquid. The washing liquid is preferably introduced into the drum for intermittent periods of 1-5 minutes duration and the intervals between these periods are preferably of 1-3 minutes duration. At the start of the operation, the liquid may be passed into the drum for rather longer periods than 1-5 minutes. The composition and/or temperature of the washing liquid may be altered during the operation. In one example,water at a temperature of 80-90C. having a washing agent dissolved therein is initially used and is then replaced by water at a temperature of 70-80C. and finally water at 10-20C.is used. According to the thickness and number of layers of the wound-up material, the perforated drum is preferably rotated at a speed of 50-300 revolutions per minute. The drum 5 is provided with a perforated jacket and a perforated hollow shaft 6. Washing liquid is supplied to the interior of the drum through a perforated shaft pin 7.

Title: Method of and apparatus for measuring the pitch angle of yarns provided with a twist
IPC: D07B7/02
Filed: 1975-08-05
Abstract: 1494264 Measuring pitch angle of yarns photoelectrically ERWIN SICK GmbH OPTIKELEKTRONIK 5 Aug 1975 [12 Sept 1974] 32693/75 Heading G1A The angle α at which a thread 12 is wound, Fig. 1, is found by illuminating the thread to cause reflections 13 and aligning a slit shutter with the reflections. In Fig. 2 (not shown), the thread moves longitudinally over a support (19), and is illuminated by a lamp (22) via a beam-splitter (20); light reflected by the thread passes via lens (18) to a rotatable slit shutter (14) and then to a photodetector (16). The detector signal is an alternating carrier signal caused by the longitudinal thread motion, and is modulated by rotation of the shutter, as in Fig. 4 (not shown). The peak signal corresponds to alignment of the shutter and the reflections 13. The shutter may be rotated by a motor (27) synchronously with the mains supply; a mains detector determines when the mains cycle passes through a given value, and this is used to define a reference point in the rotation of the shutter so that the shutter angle corresponding to the maximum photo-detector signal can be found. The shutter may be fixed and the thread moved angularly with respect to it; the lamp may be modulated to produce the carrier signal. The shutter may be oscillated rather than rotated.

Abstract: 1,256,007. Chromatographic separation of stereoisomers. ORDENA LENINA INSTITUT ELEMENTOORGANICHESKIKH SOEDINENY AKADEMII NAUK SSSR. 1 July, 1969 [1 July, 1968], No. 33135/69. Heading B1X. [Also in Division C3] Mixtures of stereoisomers, e.g. racemic mixtures, which form a complex with a transition metal ion are chromatographically separated using an optically active asymmetric sorbent in the form of a complex with the same transition metal ion. The sorbent is preferably the product obtained by treating a cross-linked chloromethylated styrene copolymer with an optically active α- or #-aminocarboxylic or -aminophosphonic acid or an amide or ester thereof and then introducing a copper or nickel ion (see Division C3), but may also be the product obtained by reacting formaldehyde with tyrosine or a derivative thereof, or be a derivative of chitosan or alginic acid. The process is particularly applicable to the separation of amino acid mixtures using water and/or ammonia as eluent, and is preferably carried out by passing the eluate containing the eluted material in the form of a metal complex through a further column of the same sorbent which is not in the form of a metal complex, whereby the metal ion is removed from the separated material. Alternatively, the sorbent in complex form may comprise the centre portion of a single bed, the upper and lower portions consisting of uncomplexed sorbent, successive runs being performed in opposite directions to ensure that the metal ion is not removed from the column and remains generally in the centre of the bed.
