Title: Improvements in and relating to plastics valve bags
IPC: B65D30/24
Filed: 1963-03-01
Abstract: 971,290. Making plastics valve bags. M. GENNERICH, and A. WINDMOLLER, [trading as WINDMOLLER & HOLSCHER]. March 1, 1963 [April 9, 1962; May 9, 1962], No. 8382/63. Heading B5D. [Also in Divisions B6 and B8] A gusseted plastics valve bag is made by flattening open one corner of a gusseted tube, inserting a valve sheet 10 (Fig. 1) beneath the comer fold 6 and welding it thereto at 11, folding the corner of the tube back to its original position and welding the valve to the walls at 15 and 16, a weld preventing means having previously been inserted. Each operation is made with the bag stationary, the movement between operations having been in the longitudinal direction of the tube. The bag is now moved transversely to strip it from the stationary weld preventing means and then again longitudinally to form an end weld. The bag is moved transversely and then back longitudinally to form the other end weld and may then be moved to another working position to form diagonal corner welds of the gussets to the bag walls at the non-valve comers. The gusseted bag tubes are initially stacked at 76 (Fig. 28), resting on angle ledges 77, 78 and rollers 79 which roll backwards and forwards without sliding on the bottom of the pile. In the position 79<SP>1</SP> the lowermost tube is gripped by suction openings 80 in the roller and is then wound on to the roller as it simultaneously rotates and moves back to its original position. The lower tube wall 1 is the first to be pulled over the angular ledge 77 and is thus separated from the upper wall 2. In the lower position the grippers 82 secured to rotating chains 81 are pivoted into the open tube, the air suction is turned off at 80 and the opened tube proceeds to the further working positions. Retaining fingers 83 on the grippers 82 prevent the wall 1 from collapsing. The valve sheet may have its internal end of thinner material than the external end, either by welding a thinner sheet to the inner end of the first sheet or by using a material of varying thickness. The varying thickness may be obtained either by extending a sheet with varying cross-section across its width or by rolling a sheet of material at intermittent intervals along its length.

IPC: B65B13/28
Filed: 1920-03-22
Abstract: 152,580. Gans, L. S. March 22, 1920. Twisting wires together.-Apparatus for tightening wire strapping around boxes and twisting the ends of the wire together to secure them comprises a revoluble device B, Fig. 1, mounted in a frame A and provided with a notched member H over which the wire ends are bent, the device B being rotated in one direction to tighten the wire around a box, and in the other direction to rotate the member H and twist the wire ends while the member B approaches the box to neutralize the resultant strain. The frame A has flanges a, Fig. 2, to engage the box sides at a corner and a screwed aperture b traversed by a screwed shank C with an attached handle D. A stem E lies within the shank and has at its upper end a clutchcollar F with a spring-pressed pin to engage ratchet teeth on the handle boss, while at the lower ends of the stem E is secured a cylindrical block G with a shoulder g on which is secured the plate member H with notches h. The wire w is passed around the box and its ends are bent over the notches h. The handle D is then turned in the direction in which the pin j rides over the ratchet teeth J and the screwed shank is moved away from the box to tighten the wire, rotation of the plate H being prevented by a ratchet M on the stem E being engaged by a spring-pressed pin mounted in a collar K, which is held against rotation by a pin l thereon engaging a lug on the frame. When the wire is tightened, the handle D is rotated in the opposite direction and, as the pin engages the ratchet teeth J, the stem E is rotated, causing the plate H to turn and twist the wire ends, the shank C moving back towards the box to relieve the strain.

Title: Improvements in or relating to the distillation of complex mixtures
IPC: B01D3/34
Filed: 1940-05-10
Abstract: <PICT:0572297/IV/1> Complex mixtures of mutually soluble liquids separable only with difficulty by simple distillation are separated by distillation with an entrainer that is completely miscible with the initial mixtures and all its components, that belongs to a chemical series which is different from any of the components of the mixture, that differs in polarity from the components to be separated, that boils below the initial boiling point of the mixture, that gives with the component removed by the distillation a vapour pressure curve which is distorted from the normal as shown in the curve C, but is not so distorted from the normal as to give an azeotropic curve B, and that does not form an azeotrope with the other components of the mixture, the mixture being distilled at temperatures rising from slightly above the boiling point of the added entrainer to slightly below the initial boiling point of the original mixture, and a one-phase liquid distillate being collected that consists of the added liquid and that component of the original mixture giving the most distorted vapour pressure curve.  The process is particularly applied to the dehydration of acetic acid using acetone as entrainer.  The pseudo azeotropic distillation may be followed by an azeotropic distillation to obtain further separation of the components.

Title: Improved pigments
IPC: C09C3/08
Filed: 1942-06-26
Abstract: Ammonium naphthenate is added to an aqueous suspension of a pigment before water is removed therefrom and the pigment dried. The amount of ammonium naphthenate is 0.5 to 15 per cent of the weight of dry pigment.  The pigment more rapidly develops maximum tinting strength and has a smaller grit content than an untreated pigment.  The invention may be applied to the manufacture of iron blues, chrome yellows, azo pigments, vat dye pigments, titanium dioxide and like pigments.  The addition is preferably made to the slurry before filtration but may be made to the pigment paste just before drying. It is made after any calcination step which may occur in the preparation of the pigment.  Examples describe (1) the addition of a solution of ammonium naphthenate to a slurry or presscake containing an iron blue pigment (2) the addition of ammonium naphthenate to slurries containing respectively chrome green, copper phthalocyanine, and a maroon pigment comprising the manganese salt of the azo dye obtained by coupling diazotised 2 - naphthylamine - 1 - sulphonic acid with 2-hydroxy-3-naphthoic acid.
