IPC: A23C11/04
Filed: 1954-07-14
Abstract: A fatty food composition comprises a fat mixture containing fatty acids with 16 to 18 carbon atoms in the chain and either myristic acid or fatty acids with chains of at least 20 carbon atoms.  The starting material may comprise an animal fat of a non-ruminant mammel, such as lard, lard oil, pig bone grease or horse oil, to which is added a glyceride or glycerides containing myristic acid. This addition may comprise a vegetable fat from plants of the families Myristicaceae, Palmae, Simurabaceae, Voclyscaceae, and Salvaoloraceae, which fat may be partly or entirely freed from fatty acids with chains of less than 14 carbon atoms by interesterification with myristic acid.

In a transformer comprising a plurality of coils on a core, each coil has a plurality of layers of spirally wound conductors connected in parallel relationship and spaced apart to provide ducts for cooling medium, ducts also being provided in the insulation surrounding the coils, in the areas of lower voltage gradient. The H.T. winding on core 22 (Fig. 2) has coils 32 to 38 comprising pairs of layers 32A, 32B to 38A, 38B the layers of a pair spaced apart by duct formers 45 to provide ducts 47 for passage of the cooling medium and parallel connected as Fig. 4 to secure negligible voltage stress between coil layers the layers being transposed midway at 32C-38C (Fig. 2). Insulation 86 between and around the coils may be L-shaped, U-shaped or flat sheets and the meeting ends 88 of pieces of sheet are bevelled, scarfed or tapered to eliminate voids which may give rise to corona. The low-voltage winding has sections 60A, 60B disposed one on each side of the H.T. winding, each section having pairs of coil layers 61A, 61B to 63A, 63B and 64A, 64B, 65A, 65B respectively, connected and insulated similarly to the H.T. winding and having ducts 74 and duct formers 72 between the layers of each pair. Insulating layers 94 insulate the H.T. winding from the core 22 and from the L.T. winding 60 and in those areas of this insulation where the voltage stress is lowest there are cooling ducts 82. The insulation in all cases is of cellulosic sheet material such as pressboard, which may be impregnated with insulating oil. Alternatively the insulation may be moulded or cast. Electrostatic screens 52, 54, with insulating layers 54 on each side the whole wrapped with Coronox insulating tape, are disposed in between the H.T. and L.T. windings. In a further embodiment (Fig. 5, not shown) there are also cooling ducts in the insulation between the H.T. coils. The H.T. coils may be closer together at the ends where they are connected together in series and the thickness of the cooling ducts in the insulation between the coils may be tapered (Fig. 6, not shown).

Patent GB-388303-A (GB)
Title: Improvements in the manufacture of cellulose esters
IPC: C08B3/26
Filed: 1932-07-28
Abstract: Cellulose organic esters of higher molecular weight than cellulose acetate are recovered from solution in organic acid by adding the solution to an aqueous non-solvent precipitating bath containing initially at least 50 per cent of organic acid.  The process is more particularly applied to the separation of the higher esters of cellulose from their esterifying mixtures.  In an example, cellulose acetatepropionate in solution in a mixture of anhydrous propionic acid and glacial acetic acid is diluted with aqueous propionic acid and acetic acid, and the solution is then poured with vigorous stirring into a precipitating liquid containing propionic acid, acetic acid, and 50 per cent of water. Further quantities of water are added during the precipitation process in order to limit or prevent increase in the concentration of organic acid.  The precipitate is readily disintegrated, washed, and filtered.  It may be washed by the countercurrent method and treated with boiling water.  The separated precipitating liquid may be used for diluting a further quantity of the cellulose ester solution.  The precipitating liquid may be concentrated and used in a subsequent esterification process.  In another example, cellulose butyrate dissolved in a reaction p  mixture of butyric acid and monochloracetic acid is diluted with aqueous monochloracetic acid and the solution is poured with stirring into 52 per cent monochloracetic acid, water being added at a rate sufficient to keep the concentration constant.  Other esters which may be treated by the process are cellulose propionate, acetate-butyrate, and acetate-stearate. Specifications 287,880 and 290,571, [both in Class 2 (ii), Cellulose &c.], are referred to.

Title: Improvements in and relating to supports for lids of gramophone cabinets and other receptacles
IPC: E05F3/02
Filed: 1929-07-11
Abstract: 336,285. Spratt, H. Hart-. July 11, 1929. Stays; checks. - A telescopic stay is provided with mechanical means for locking it in its extended condition, the lock being removed by a slight further extension of the stay, and the telescoping members form piston and cylinder of a fluid dash-pot for checking the closing of a gramophone or other cabinet lid to which the stay is applied. The dash-pot piston 15 is tapered towards both ends and is free to slide axially upon a neck 14 formed in the plunger 11. The halves of a ring 18, which is divided diametrically, are pressed inwards by a spring 19 and ride upon the plunger when the stay is strut. In extending the stay, the piston 15 moves to the lower end of the neck 14 and ultimately the ring halves 18 snap below the shoulder 14a of the plunger 11, as shown in the left-hand halves of the Figures. The coned piston is forced past the ring halves by a further extension of the stay and in the subsequent closing movement slides to the upper portion of the neck 14 and there holds the ring halves open until the shoulder 14a enters between them. The cylinder element 10 is surrounded bv a second cylinder 1 which forms a reservoir, liquid being drawn into cylinder 1 past a ball valve 7 and discharged, after leakage past the piston, over the rim of the cylinder.

Feeding webs.-In a, tape web-threading device for rotary printing-machines, the means for guiding the tape through the printing and impression cylinders are located beyond the ends of the cylinders and clutch mechanism is provided for temporarily transmitting drive to the tape when it is desired to thread the web. The tape 4, Fig. 1, passes in a closed loop around pulleys such as 6 and 7 located at one side of the machine. As shown in Fig. 4, the pulley 5, around which the tape also passes, is rotatably mounted on the shaft 8 of the impression cylinder 1 and is of the same diameter and coaxial therewith. A hand-wheel 11 carrying pins 9 is slidably mounted inside the pulley 5 and positively connects the latter to the impression cylinder 1, by engagement of the pins 9 in apertures 13 in a ring 14 secured to the shaft of the impression cylinder. The hand-wheel is located in its " in " and " out '' positions by means of a spring-pressed ball 15 bearing in recesses in the boss of the pulley 5. The pulleys 6 are loosely mounted at the ends of the rollers over which the web runs. To effect the threading of the web, the pulley 5 is engaged with the impression cylinder, the web attached to the tape, and the press inched round until the web-threading operation is completed, whereupon the web is detached from the tape and the clutch mechanism thrown out of operation.
