Abstract: 1,106,820. Separating mixture by distribution between two immiscible liquids. CIBA Ltd. 24 Sept., 1965 [25 Sept., 1964], No. 40838/ 65. Heading B1F. Components of a mixture are separated by repeatedly distributing the mixture between two immiscible liquids in an apparatus comprising a series of interconnected chambers 15 defined by walls 7 transversing a cylinder 6, the apparatus being inclined at 30 to 60‹ to the horizontal (Fig. 2, not shown) and the apparatus being rotatable at such a speed as to cause rapid renewal of the liquids near the interface but to prevent emulsification by maintaining a coherent interface. Prior to the separation and with the assembly rotating the denser liquid is fed into the uppermost chamber through pipe 12 until it overflows through pipe 14 from the last and lowermost chamber, the lighter liquid is then introduced through pipe 12 until only the lighter liquid overflows from the last chamber, a part of the denser liquid in each chamber having been displaced. The mixture is then introduced into the first chamber which has been emptied, and to effect separation the light liquid is continually introduced through pipe 12 with assembly rotating, the fraction being collected from pipe 14. The cylinder is formed of a plurality of synthetic resin rings in tight sealing engagement with one another. The transverse walls are of stainless steel, and the plate openings 8 in adjacent plates, are displaced relative to one another, e.g. by 180‹ as shown. The outlet pipe from the last chamber may comprise a syphonic gas barrier (Fig. 7, not shown).

Abstract: 1,254,841. Reciprocating motors; compressed gas engines. BUTTERWORTH HYDRAULIC DEVELOPMENTS Ltd. Dec. 4, 1968 [Sept. 8, 1967], No. 41082/67. Headings F1A and F1M. In a fluid-pressure operated motor of the type in which reciprocation of a differential pressure biased piston 17 is controlled by reciprocation of a differential pressure biased spool 16 itself controlled by movement of the piston, the arrangement is such that the volume of fluid input equals the volume output, whereby intermittent exhaust back pressure is avoided. In the embodiment illustrated, a land 16d of the spool 16 controls a port 5a so that, when the piston 17 moves against its bias, i. e. in the direction of arrow Y, the volume of fluid displaced from the constant pressure piston chamber 13 passes through passages 4, 5 to the alternating pressure piston chamber 12, Fig. 1, and, provided the crosssections A2, A3 of piston lands 17b, 17c are such that A2 is greater than A3, which is greater than A1, the piston rod cross-section, the volume of fluid exhausted from a variable volume chamber 14 equals the volume entering the alternating pressure piston chamber 12 from the input. When the piston 17 moves in the direction of its bias, Fig. 3 (not shown), the excess of fluid displaced from the alternating pressure piston chamber 12 over that passing into the constant pressure piston chamber 13 passes to the variable volume chamber 14, the rest of the fluid passing to the exhaust.

Abstract: 865,349. Wrapping-machines. FORGROVE MACHINERY CO. Ltd. Nov. 30, 1959 [Dec. 22, 1958], No. 41369/58. Class 94(1). Packages formed by tubing a web 10 about spaced articles such as piles of biscuits 18 and then sealing and severing the tube at intervals, are gripped at their seals by cooling blocks, are carried forward at a speed greater than that at which they are fed to the severing means. The tube and articles are fed by opposed belts 21 over a longitudinal seam sealer 22 to rotary cutting and sealing means 23. The web and tube feed may be controlled by photoelectric means (not shown) to locate accurately printing &c. As each package is severed from the tube, its leading seal is gripped by cold blocks 26 which also grip the trailing seal of the preceding package. The greater speed of the blocks 26 causes gaps between the packages which facilitate feed adjustment by the photoelectric means and also permit deliberate variations of package length.

Milk is concentrated to a dry solids content of at least 30 per cent rennetted at 15-30C. for 5-15 minutes to insolubilise the cosein and obtain a homogeneous non- gelled mass, cooling to below 10C., dividing into a plurality of parallel flow streams, for example threads or lamellae, which are heated substantially instantaneously to 25-45C. to polymerise the cosein, washing the resulting curd in an aqueous bath, separating the curd, and collecting it in a homogeneous mass. The heating may be effected by passing the streams in direct contact with a heated bath, by passing the streams through tubes of appropriate cross section in a heat exchanger, or by means of high frequency electric fields. On entering the bath, desirably the streams are divided, transverse of their direction of motion, for example, by a rotating knife.
