Abstract: 867,583. Washing granular materials. CANNON, H-B. Sept. 12, 1957 [Sept. 27, 1956; June 14, 1957], No. 28769/57. Class 82(2) A slurry separating apparatus has an array of convergent troughs sloping downwardly and radially inwardly to a common outlet circle, a ring supporting the outlet ends of the troughs, a sharp-edge splitter element adjacent the outlet ends of the trougs, means for supplying slurry to the troughs comprising a circular channel disposed above and within the inlet ends of the troughs, outlets in the base of the channel and downwardly and outwardly sloping segments connecting the outlets from the channel with the inlets to the troughs. As shown, a circular array of troughs 12 are supported on a frame 10, the troughs sloping inwardly and downwardly and being supported at their outlet ends by a ring 42, shaped as a curved continuation of the floor of the troughs. Slurry is supplied from a tank 38 through pipes 36 to a channel 18 from which it flows to segments 24 which diverge downwardly and outwardly to a width corresponding to the width of the troughs. Baffles 32 may be provided in the channel to assist in producing an even flow of slurry to each trough. The stratified slurry flowing from the ends of the troughs meets a splitter element 54 having sharp edges 92 and 102 (Fig. 10) which divide the stream into three products. The position of the edges 92 and 102 may be adjusted by means of cables 116 and 130. U.S.A. Specifications 2,766,882 and 2,769,545 are referred to.

Patent GB-697668-A (GB)
Title: Lubricating compositions
Filed: 1950-11-24
Abstract: Textile lubricants free from water and inorganic salts are prepared by distilling the water for example, under sub-atmospheric pressure, from the neutralized sulphonation product of a fatty acid containing at least 10 carbon atoms or an ester thereof, blending the residue with lubricating oil and separating undissolved inorganic salts from the product.  Oleic acid is the preferred fatty acid, and esters referred to are vegetable or animal oils or fats, for example rice oil, olive oil and peanut oil.  The neutralized sulphonation product of a mixture of mineral oil, vegetable oil and fatty acid is particularly mentioned.  The sulphonating agent may be oleum and the neutralizing agent an aqueous solution of an alkali, for example sodium or potassium hydroxide.  The inorganic salts may be separated from the lubricating composition by filtration, using a filter aid such as diatomaceous earth or bentonite.  An alkyl phenol, for example diamyl phenol, may be included in the sulphonation mixture. Lubricating oils referred to are mineral, animal or vegetable oils and mixtures thereof.  Specifications 649,148 and 644,415 are referred to.

Abstract: 1,041,728. Freeze drying. LEYBOLDHOCHVAKUUM-ANLAGEN G.m.b.H. July 22, 1963 [July 24, 1962], No. 28871/63. Heading F4G. [Also in Division A2] In the freeze-drying of frozen material such as sensitive foods of vegetable or animal origin and juices and extracts of the foods, the frozen material is rapidly cooled to a temperature below that at which it was initially frozen and the material is freeze-dried subsequently to such cooling. The frozen material preferably is cooled to a temperature between 10‹ and 50‹ C. below its eutectic point whereby any thawing of the material during freeze-drying is avoided. The cooling referred to may be undertaken either in a separate vacuum chamber, for example at the input lock of a freeze-drying production line, as described in Specification 960,602, or in the actual freeze-drying apparatus employing an auxiliary means for the removal of water vapour of substantially smaller capacity than that of the vapour removal means of the freeze-drying apparatus proper.

Title: Improvements relating to electrical systems for remote transmission of mechanical movements
Inventor: NILSON JOHN ROBERT
IPC: G08C19/06
Filed: 1954-10-07
Abstract: 761,950. Electric follow-up systems. HAYS CORPORATION. Oct. 7, 1954, No. 28907/54. Class 40 (1). In a positional control system using similar differential transformers having movable magnetic elements at the transmitter and receiver, the number of transmission lines is reduced to three by connecting the transmitter and receiver transformer primaries 11-12, 22-23 in a series loop across the A.C. supply 26-26 by the lines 14, 15, and connecting the secondaries 13-24 by the third line 19 in series with the usual unbalance detector 30 across the point 18, common to the transmitter primary coils 11- 12, and a point 29 whose potential is mid-way between that of the supply terminals 26. Any movement of the transmitter magnetic element results in an error signal in the line 19 which in the usual way operates a motor 33 to move the magnetic element of the receiver into correspondence, e.g. through a cam 35, and actuates an indicator 34 or recorder. In a modification, Fig. 2 (not shown), the potential of the point 29 is made variable by using a tapped potentiometer to inject a voltage into the line 19 to compensate for resistance changes therein with temperature. The transformers may comprise E-type magnetic cores with pivotal armatures, Figs. 3, 5 (not shown), or, when measuring the thickness of a non-magnetic sheet 90, e.g. of glass, Fig. 4, an H-type core may be used having the secondary coil 13 on the cross limb 87 and the primaries 11-12 on the limb 86. The transformer then senses the distance of the magnetic base member 89 from the limbs 85-86 relative to the fixed distance therefrom of an armature 88.
