Patent GB-763474-A (GB)
Title: Improvements in or relating to the production of fatty acid monoglycerides
Inventor: SULLY BERNARD THOMAS DUDLEY
IPC: C11C3/06
Filed: 1954-02-09
Abstract: Fatty acid monoglycerides are produced by reacting with glycerol in the presence of tertiary butyl alcohol and an alkaline catalyst a di- or tri-glyceride of a fatty acid which is substantially insoluble in water, or a mixture of glycerides of said fatty acids, the glycerol being in excess of that required to form the monoglyceride, and separating from the reaction products a product consisting mainly of monoglyceride; any water present in the reaction ingredients being removed before commencing the reaction.  Neutral animal or vegetable oils, e.g. tallow or hydrogenated tallow, olive oil, linseed oil, soya bean oil, castor oil, and a mixed blend of oils as used in margarine manufacture, may be used with 50-60 parts by weight of glycerol for every 100 parts by weight of oil.  The oil is conveniently dissolved in t-butanol containing hexane and the mixture distilled to remove water.  A mixture of mono-, di- and tri-glycerides may be prepared by heating the free fatty acid with glycerol to 200 DEG  C.  The product, after dissolving in t-butanol and dehydrating by distillation, may be used as starting material. Suitable catalysts are sodium methoxide, sodium t-butoxide, and magnesium alkoxides.  The preferred catalyst is sodium or potassium glyceroxide prepared by dissolving alkali metal hydroxide in glycerol and removing water by distillation.  The glycerol solution of catalyst may be added to the solution of oil in t-butanol and the mixture allowed to stand for 24 hours.  The catalyst is then neutralized, e.g. with citric acid, and the t-butanol recovered by distillation under reduced pressure, water being added in the later stage of the distillation.  The residue is allowed to separate into two layers, an upper layer of monoglycerides and a lower layer of aqueous glycerol.  In some cases, the monoglyceride may be allowed to crystallize out with out neutralizing the catalyst and the mother liquor after filtering off the monoglyceride may be used for the preparation of fresh monoglyceride.  Detailed examples are given of the preparation of glyceryl mono-oleate from olive oil, and glyceryl monostearate from a mixture of mono-, di- and tri-esters produced by heating glycerol and stearic acid.

Title: Improvements in or relating to grapnels for submarine cables
Inventor: BROCKBANK ROBERT ALSTON
IPC: B63C11/50
Filed: 1960-02-03
Abstract: 971,152. Grapnels. POSTMASTER GENERAL. Jan. 30, 1961 [Feb. 3, 1960], No. 3917/60. Heading B7S. A submarine cable grapnel comprises a framework 15 with at least two prongs 1 and 2, 3 or 4, cable engaging surfaces 9 which are movable longitudinally of the grapnel, sea bed engaging flukes 30 which are normally held in the inoperative position (full lines, Fig. 4) and a linkage between the flukes 30 and surfaces 9 such that, in use, on the application of a predetermined pressure on the surfaces 9, the flukes 30 are released to the operative position (shown in dotted lines, Fig. 4). The linkage comprises a rod 8 having an eye-bolt 33 at one end and a collar 27 at the other which causes the flukes 30 to rotate about pivots 31 when the rod is moved axially. The rod is prevented from making this movement by a collar 20, secured to it by a shear-pin 21, which abuts extensions 10 of the surfaces 9. When the cable is located by the prongs 1 or 2 and engaged by the surfaces 9, which are knife-edges, it exerts a gradually increasing pressure until the shear pin 21 fails thereby allowing movement of the collar 20 with respect to the rod 8. The bell-crank levers 23 are then moved out of engagement with the collar 25 and the rod 8 is allowed to move to a position which allows the flukes 30 to move to the sea bed engaging position. This resistance to movement of the grapnel results in an increase in tension of the towing cable which can be detected by the towing ship whereupon it steams to a position above the grapnel and lifts it vertically until the tension in the submarine cable causes it to be severed against the knife-edge 9. The grapnel may be provided with clamps to hold a severed end of the cable. The surfaces 9 may be non-cutting surfaces which will lift the cable without damage. The surfaces 9 may be replaced by pulleys. A second grapnel may be secured to the rear end 16. A planing board may be provided to ensure the prongs 1 or 2 pick up the cable. The sea-bed engaging part may be separate from the cable engaging part, the two being joined by a coupling which allows the former to move to operating position when the cable is located. Specification 703,782 is referred to.

Title: Improvements in and relating to motion picture film magazines
IPC: G03B21/32
Filed: 1920-02-09
Abstract: 138,878. Burnett, J P. Oct. 9, 1917, [Convention date]. Kinematograph apparatus.-A magazine for an endless film comprises a vertically-disposed circula.r casing 4 having an opening 11, a rotary disk 8 forming its back, and radially-extending curved vanes 10 on the disk 8. The front of the magazine has a hinged door 12. The film is fed into the magazine by rollers 15, and is caused to fold upon itself by blades 16, 17, fixed respectively below the rollers and on the door. The weight oi the film which accumulates on the vanes 10 causes the disk and vanes to rotate and carry the film which is to be withdrawn up the opening 11. The rotation of the disk &c. is facilitated by mounting it on roller bearings, and by the curvature of the blades, this curvature tending to shift the film on entry towards the wall of the magazine and so increase its leverage, and on the other side of the magazine to shift the film towards the centre and decrease its leverage.
