The filter cake may be washed with an ammonium chloride solution to remove any occluded alkali metal chloride.  Specified alkanolamines are mono-, di- and tri-ethanolamine, mono-, di- and tri-butanolamines derived from 1- and 2-butanol, N-methyldiethanolamine, N,N-dimethylethanolamine and N,N-diethylethanolamine. The aqueous solutions are used as optical brighteners (see Division D1).ALSO:Aqueous compositions for use as brightening agents for cotton fibres and papers comprise alkanolamine salts of 4, 41-bis \sV4-[metanilino] - 6 - [bis(2 - hydroxyethyl) amino] - 1 3.5 - triazine - 2 - yl - amino \sV - stilbene - 2, 21 - disulphonic acid prepared by treating an aqueous solution of the alkali metal salt of the sulphonic acid with ammonium chloride at a temperature below 30 DEG C to precipitate the partial acid salt as a slurry, acidifying the slurry at 0 DEG -30 DEG C with HCI to a pH 1.0-4.0, filtering the slurry and reacting the wet filter cake with at least 4 mols alkanolamine per mol acid, boiling the mixture to produce an aqueous solution of the alkanolamine salt and if necessary, adding water to adjust the concentration of the salt to about 15% by weight, based on total solution.

The groups 1 and 2 have a space b therebetween. A first fluid (such as water or liquid sodium) circulates through the spaces a and b. The compartments 3 and 4 are respectively connected by manifolds 15, 16 and 19, 20 which provide for circulation through the compartments of a second fluid (e.g. water from which steam is formed). Each manifold connects lateral extensions of the compartments. The lateral extensions as shown are formed by corners of parallelograms but can be formed in other ways, e.g. as illustrated in Figs. 3, 4 and 5 (not shown). The adjacent groups 1, 2 of compartments in each bank are arranged in opposite orientation with symmetry with respect to an axial mid-plane at right angles to the plane of the compartments. Thereby the admission and discharge manifolds of adjacent groups in a bank occupy a staggered position in relation to one another. The compartments may be formed by sheet metal members 5 and 6 and a peripheral strip 7 joined by welding.

Abstract: 528,873. Luminescent materials. GENERAL ELECTRIC CO., Ltd., JENKINS, H. G., and RYDE, J. W. May 16,1939, No. 14599. [Class 39 (i)] Luminescent material comprising cadmium tungstate so activated that it is excited by radiation of wave-length 3650A and emits luminescent light whose dominant wave-length is considerably longer than that emitted by known magnesium tungstate when excited by radiation of wave-length 2537Š, is combined with an electric discharge device so as to be excited by the radiation therefrom. The activator may be uranium or bismuth or a mixture thereof. One method of preparing the material consists of dissolving 198 gm. of sodium tungstate of AnalaR grade (" AnalaR " is a Registered Trade Mark) in I litre of distilled water to form solution A. 154 gm. of cadmium sulphate of AnalaR grade is dissolved in 1 litre of distilled water to form solution B. 10 ml. of solution A is added to solution B, and the precipitate filtered off and discarded. The rest of solution A is added to the filtrate. The precipitate is filtered off, washed six times with hot distilled water, and dried at 180‹C. 0.1 per cent of uranium, in the form of nitrate, is added and the mixture dried at 180‹C. The solid is ground and heated to 1,000‹ C. in a silica boat for one hour in air. It is reground lightly, washed six times with boiling distilled water, dried at 180‹ C. and sieved to give a suitable size of particle. The luminescence excited by radiation of wave length 3650Š is red. 0.5 per cent of bismuth, in the form of chloride, may replace the uranium but preferably the proportion is 2-3 per cent and the luminescent light is yellow. Specification 527,685 is referred to. The Provisional Specification states that gold may also be used as activator.

Abstract: 1,213,200. Sheet forming BORG-WARNER CORP. 27 March, 1968 [10 April, 1967], No. 14681/68. Heading B5A. In a process for cold drawing hollow articles from plastics sheet material, the sheet is initially peripherally clamped under a first pressure and, during the drawing operation, the pressure is reduced to a lower value. This prevents wrinkling and fraying of the lip of the article and increases its dimensional stability. In the described embodiment, the sheet is drawn between co-operating male and female dies 16 and 32 and is initially applied by the female die against an annular draw pad 26 having an outer peripheral ridge 40. In operation, the sheet is initially clamped against the ridge by forward movement of the female mould, further movement of the mould causing the sheet to be drawn over the male mould. At a predetermined instance during the drawing stroke, the sheet is completely drawn off the ridge into the larger gap adjacent thereto thus causing the desired decrease in clamping pressure on the sheet.

Abstract: 572,612. Grinding toothed face clutches. ABBEY, A. (Gleason Works). Sept. 8, 1943, No. 14755. [Class 60] [Also in Groups XXII and XXIV] A toothed face clutch member 20 has teeth formed so that opposite sides of spaced teeth lie in common surfaces of revolution. The teeth may be cut with a face mill cutter 30, Figs. 3 and 4, having outside cutting edges 31 and arranged so that sides 23a, 24b of two spaced teeth 22a, 22b are cut simultaneously. After one side of a pair of teeth has been cut, the cutter is removed from the work, the latter is indexed one tooth pitch, and a second cut is made. The process is repeated until all the teeth are completed. The teeth of the companion clutch half 21 may be cut with a face mill cutter having inside cutting edges. The radii of the curved sides of the two sets of teeth may be the same or different. The teeth may be of constant depth from end to end and the cutting tool may round off the tops and the bottoms of the teeth during the cutting operation. The feeding movement of the cutter may be inclined both to the axes 32, 28 of the cutter and the work. The side tooth faces may be of positive pressure angle, Figs. 2 and 4, or of zero pressure angle. The axes of the cutter and work may be parallel to one another, or as shown in Fig. 27, the axes 222, 236, may be mutually inclined. In the latter case the direction of feed 237 is inclined to both axes 222, 236, and the root lines 243 of the tooth spaces will be inclined to the pitch line 240. Figs. 10 and 11 show a method of chamfering the teeth. A face mill cutter 85 has outside cutting edges 86 of concave profile and has its axis 87 inclined to the root plane 88. The clutch members may be used in a releasable clutch or they may be coupled together by bolts. Oscillatory cutting tools or grinding- wheels may be used instead of face mill cutters.
