Title: Process for removing higher-melting fatty materials from glyceride oils
IPC: C11B7/00
Filed: 1962-09-21
Abstract: The subsequent separation of higher melting fatty material from glyceride oils is facilitated by the addition of 0.001-0.5%, by weight of the oil, of a sucrose fatty acid ester which contains not more than 5 unesterified hydroxyl groups per sucrose molecule and which contains at least one residue of a C12- 22-fatty acid and at least one residue of a C2- 6-fatty acid, the C2- 6-acids comprising 5-100% by weight of the C12- 22-acids.  The oil, which is suitably cotton-seed oil, corn oil, palm or palm kernel oil, hydrogenated soyabean oil, or a directedly re-arranged glyceride oil may either be heated with the additive until all the fatty material present is liquid before being cooled, or, alternatively, the oil may first be completely liquefied by heating and the additive then added.  The preferred additive is sucrose tetraacetate tetrapalmitate. Specification 604,136 is referred to.

Title: Improvements in or relating to matching systems for wave guides
IPC: H01P5/08
Filed: 1954-12-13
Abstract: 772,631. Waveguide impedance-matching. SIEMENS & HALSKE AKT.-GES. Dec. 13, 1954 [Dec. 22, 1953], No. 36052/54. Class 40 (8). A waveguide impedance matching system comprises an adjustable capacitative and/or inductive diaphragm 4 so mounted that the effective area of the diaphragm (which determines its reactance) is variable in situ and in addition the diaphragm itself is displaceable in the direction of the axis of the waveguide. The system shown is designed to provide matching between a waveguide 1 and the input or output antenna 2 of a helix 3 forming the slow-wave structure of a travelling-wave tube. The reactance of the diaphragm is varied by rotating it about a thin metallic or ceramic spindle 5 which passes through a slot 6 in the narrow wall of the waveguide. This slot enables the diaphragm to be displaced axially. Resilient metal plates 7, 8 on either side of the slot provide metallic contact between the diaphragm and the waveguide. Alternatively the connection between the diaphragm and the waveguide may be capacitative. The diaphragm may be mounted in a section of the waveguide which is telescopically displaceable along the remainder of the guide. Two diaphragms may be used instead of one, one of them being displaceable.

Title: Boric acid dehydration
IPC: C01B35/10
Filed: 1965-08-24
Abstract: Orthoboric acid is dehydrated by maintaining a slurry thereof, in an organic liquid, at a temperature of 110-160 DEG  C., until at least 50% is dehydrated to metaboric acid.  Further dehydration of the boric acid may be carried out at a higher temperature.  The organic liquid may be a saturated or unsaturated hydrocarbon having 4-30 C atoms or a hydrocarbon substituted by, e.g., hydroxyl, sulpho, nitrile, borate, or carboxyl groups.  The orthoboric acid may be present as 0.1-20% by wt. of the slurry. The slurry may be introduced continuously into a large body of the organic liquid maintained at the required temperature, a continuous stream of metaboric acid slurry being withdrawn therefrom.  Gases inert to the reactants, e.g. N2 or air, may be used as stripping gases.  The distillate of organic liquid and H2O may be condensed, separated and the organic liquid recycled to the reaction.ALSO:Borate esters are produced by contacting with molecular oxygen a slurry of metaboric acid produced by heating a slurry of orthoboric acid in an organic liquid to a temp. of 110 DEG -160 DEG  C. until at least 50% of the acid is dehydrated to metaboric acid. The orthoboric acid may be further dehydrated by heating at a higher temp. before the oxidation.  The organic liquid may be a saturated or unsaturated hydrocarbon having 4-30 C atoms, or a hydrocarbon substituted by e.g. OH, sulpho, nitrile borate or carboxy groups.  In the example a slurry of metaboric acid in cyclohexane is produced, oxidized at 120 DEG  C. with O2 to the ester, and then hydrolized to produce cyclohexanol and cyclohexanone. The boric acid produced in this hydrolysis is recovered and recycled.

Title: Coating method and apparatus
IPC: B05D1/36
Filed: 1960-10-27
Abstract: A method for coating, more particularly moisture-proofing, discrete particles, such as glass beads, while advancing the same along a feed path, comprises the steps of continuously feeding a mass of the particles to be coated along said path, increasing the depth of the particle mass as it is fed along a portion of said path portion, applying a silicone material, which <PICT:0902554/III/1> term includes any of the polymerizable silicanes, such as silanes or polysiloxanes which are capable of undergoing further polymerization, to said particles during the agitation thereof, and curing said material so as to form a uniform coating on each of said particles. The curing may be carried out by the addition of an activator or by heating.  As shown, beads from a delivery hopper 6 are introduced into conveyer 5 comprising a screw 8 mounted in shaft 9 and driven by electric motor 10, and consisting of an infeed section A, an intermediate section B and an outfeed section C, in a trough 30. As the beads pass from section A to section B their rate of movement is slowed down by the introduction of mixing bars 20 between the flights of the screw 8, paddles 24 on each flight and openings 22 in each flight, and thus the depth of the beads is increased.  In this section the beads are treated with an activator, e.g. a water-soluble silicate or other aqueous alkaline solution, which enters trough 30 from tank 40, after which treatment the beads come in contact with the silicone material, preferably in liquid form, (a list of suitable silicones being given) which enters trough 30 from tank 45.  The silicone is completely dispersed throughout the beads as a result of the violent agitation of the particles, which agitation continues till the particles pass to section C in which the level of the particles drops to the original level and the beads are then discharged into bin 7 via conduit 52.

Abstract: 962,247. Knitting-machines. WILLIAM COTTON Ltd. Oct. 17, 1962 [Oct. 19, 1961], No. 37460/61. Heading D1C. A full cardigan rib fabric is produced on a straight bar knitting machine in which the frame needles tuck in alternate courses, characterised by the operational steps, carried out during the production of the tuck courses by the frame needles of separating the old machine needle loops OML including the machine needle tuck skitches MTL, on the shanks of the machine needles from the machine needle new loops MNL in the beards of the machine needles 3 at the machine needle beard pressing stage, and retaining the frame needle selvedge tuck loops FTL on their selvedge frame needle, so that these selvedge tuck loops are thereafter formed ininto knitting selvedge loops. This separation is brought about by causing the frame needles 1 to draw a slack course so that the machine needle tuck loops are enlarged and tend to trail behind when the machine needles advance to the needle beard presser. The retention of the selvedge tuck loops is effected by closing of the selvedge frame needle beard 2 by an individual presser element. The retention of the selvedge tuck loops on the selvedge frame needle may also be effected by an inward rack of the thread carrier 44 when the frame needles are lowered so that the selvedge yarn becomes wrapped around the selvedge frame needle shank. (Figs. 18-20). A quality cam 38 Fig. 14 (not shown) mounted on the machines main cam shaft produces the slack courses. A catch 74 (Fig. 22) is releasable for rendering the mechanism ineffective when required by operation of a solenoid 81 connected to it by a link 82, there being suitable control by springs 83, 84. A rise 80a on the cam 80 operates the mechanism to engage the truck 67 with the cam 68 whereby the truck lever 62 is operated to back rack the lead screw 61 at the times required.
