Abstract: 1,229,360. Potassium magnesium sulphate chloride. NATIONAL LEAD CO. 18 July, 1969 [18 July, 1968], No. 36276/69. Heading C1A. Kainite, KC1.MgSO 4 .3H 2 O is produced by moistening a double sulphate of potassium and magnesium, e.g. leonite, K 2 Mg(S0 4 ) 2 4H 2 0, or picromerite K 2 Mg(S0 4 ) 2 .6H a O, with 10% or less by weight of water in the presence of magnesium chloride and then aging the mixture at a temp. of from 25 to 40 C. for a period sufficient to effect such conversion. Preferably the double sulphate is moistened with 10% by weight of an aqueous solution containing at least 20% by weight of magnesium chloride. The aging preferably extends over a period of at least 48 hours, and the double sulphate to be treated may have been obtained by the evaporation of a natural brine, with elimination of the sodium chloride first formed and evaporating the residual solution to deposit the desired double sulphate. The mother liquor from this deposition may be used as the source of magnesium chloride. The contaminated product of the present process may be purified by flotation.

Abstract: 1,231,638. Photopolymerizable products. BADISCHE ANILIN- & SODA-FABRIK A.G. 20 Sept., 1968 [22 Sept., 1967], No. 44781/68. Heading C3P. [Also in Division G2] Photopolymerizable compositions in the form of plates, sheeting or film contain a photopolymerizable compound having at least two olefinic double bonds and an indigoid dye (which serves as a visible marker for indicating the extent of photopolymerization when the compositions are exposed to a light source). The compositions generally include a vinyl polymer, polyester, alkyd resin or cellulose ester or ether as the base material, and a photoinitiator (e.g. diacetyl, benzil and benzoin compounds) in an amount of 0À01-10% by weight of the composition. A polymerization inhibitor is also preferably included in the compositions. The poly-unsaturated monomer is preferably one that contains amide, urethane or urea groups, e.g. bis-(meth)- acrylamides. Monoolefinically unsaturated compounds may additionally be present in minor amounts, e.g. (meth)acrylamide, styrene and alkylene glycol mono(meth)acrylates. In an example a photopolymerizable composition comprises a copolymaide, m-xylylene-bis-acrylamide, triethylene glycol bisacrylate, the diether formed from ethylene glycol and methylolacrylamide, N-methoxymethylmethacrylamide, benzoin methyl ether and the cyclohexylammonium salt of N-nitrosocyclohexylhydroxylamine (inhibitor).

Abstract: 1,231,938. Holography. XEROX CORP. May 12, 1969 [May 14, 1968], No.24020/69. Heading G2J. In a method of forming holographic images an object modulated beam of coherent radiation is directed at one face 26 of a photo-hardenable layer 28 and a reference beam of coherent radiation, in phase with the object beam, is directed at the other face 12 to create a standing wave interference pattern in and at the faces of said layer to create a corresponding change in and at the faces of said layer in resistance to a solvent to produce surface relief holographic recording. Preferably the vector direction of the reference beam is other than perpendicular to the photo-hardenable layer and forms an angle of between 90 degrees and 180 degrees with the direction vectors of the object beam. The two beams are collimated. After exposure the photo-hardenable layer is developed in a suitable solvent to form at least one blazed surface. A self-supporting layer will form two such surfaces and can then be split to give two holograms. The blazed surface may be coated with a reflective material e.g. aluminium, gold, silver, chromium. Desirably the minimum direct distance of the top of the riser portion of each step in the blazed surface above the tread portion is between 0À05 and 10 microns. The image is reconstituted in the usual way. If the photo-hardenable material is self-supporting the surface relief may be produced on both its faces, and the layer hologram split to give two separate holograms.

Abstract: 1,250,557. Resolutions of lysine. STAMICARBON N.V. 30 Sept., 1969 [2 Oct., 1968], No. 48076/69. Heading C2C. A salt of an optical antipode of lysine with sulphanilio acid is produced by forming a supersaturated solution of a mixture of salts of the optical antipodes of lysine with sulphanilic acid, separating an optically active salt from the mixture by selective crystallization, and also racemising the non-desired optionally active salt of lysine and sulphanilic acid by heating an aqueous solution of the salt, e.g. at about 200 C. Crystallization may be effected by sealing, and both enantiomers may be obtained from successive crystallization operations; also subsequent saturation of the mother liquor from the crystallization of one form with the racemic salt yields the other antipode. The optical purity of the lysine sulphanilate salt may be increased by treatment with a solvent, e.g. water or aqueous alcohols or ketones, which produces a solid phase of greater optical purity in contact with a saturated liquid phase. Optically active lysine is recovered from the sulphanilate salt, e.g. by use of ion-exchange resin techniques. Specification 1,191,100 is referred to.

Abstract: 1317775 Packaging CHRISTENSSONS MASKINER & PATENTER AB 2 June 1970 26442/70 Heading B8C A cardboard carton is closed by a thermoplastics foil 135 which is heat-sealed to the end of the carton and which has a border 36 lying on the carton side walls. Simultaneously with the sealing of the border 36 to the side walls, the border and the side walls are pressed inwardly to give the formation shown in Fig. 5. Crimping of the border 36 is thus reduced and the quality of the seal improved. The carton has an internal groove 38 which can accommodate excess material resulting from the carton deformation. The corners of the foil may be cut off as shown in Fig. 3 to avoid the presence of excess material at the corners of the carton after sealing, which excess could lead to leakage. Prior to application, a foil is gripped by a suction device 44 which is associated with a heat sealing head 46. After its location over a carton, the heat sealing head is lowered to seal the carton. Inclined surfaces 57 on the head seal the foil border and deform the carton. A recess 58 in the head forms a bead around the edge of the carton top to take up any expansion of the central region of the foil. In a modification (not shown), only the parts of the side walls adjacent to the junctions between the side walls are pressed in.

The datum stop may be of variable width and constructed in the form of a pair of wedges 8a, 8b the former fixed and the latter longitudinally displaceable to effect the variation in width. In operation the datum stop 8 is adjusted to a desired width and the spacer assembly 10 displaced to bring a selected rod into alignment with a stop 12 on an abutment member 13 attached to a work-table 2 on the machine tool. Engagement between the stop 12 and the positioning device is effected by an actuator 16 which displaces the member 13 which is movable relative to the table 2 to effect abutment between the stop 12 and a selected one of the rods 10.
