Title: Improvements in or relating to method of recovering oils from oleaginous meats of nuts, beans, seeds and the like
IPC: C11B1/00
Filed: 1953-04-23
Abstract: Fatty oils, particularly coconut oil, are extracted from the meats of nuts, beans, seeds, &c., by pressing the juice therefrom, centrifuging the juice to obtain an oily cream and an aqueous milk, subjecting the cream without fermentation to temperatures between 30 DEG F. and 120 DEG F. for less than eight hours to break the cell walls of the emulsion, raising the temperature of the cream (if necessary) to 100 DEG F. to increase enzymatic action and break the oil emulsion, and finally centrifuging to <PICT:0747187/III/1> separate the oil from the aqueous liquid.  Either of two treatments to break the emulsion may be used, a short chilling treatment or a longer warming treatment.  In the chilling treatment, the cream is chilled to 30 DEG -50 DEG F. and then warmed to 80 DEG -120 DEG F. to induce the activity of the natural enzymes to break the emulsion.  In the warming treatment the cream is warmed to 80 DEG -120 DEG F. for a period of several hours.  Only a few minutes is required in the chilling treatment.  In a suitable plant, coconut meat is shredded in a shredder 10 and passed to a press 14 to expel the juice, which is then supplied to a centrifuge 18 from which the cream is discharged through line 21 and the aqueous milk through line 23 to a tank 25. The cream is then subjected to either of the above enzymatic treatments.  Using the chilling treatment, the cream is delivered to a chilling drum 30 and the scrapings of solid cream therefrom are dropped into a melting device 34 and warmed to the above temperatures.  The melted cream, now broken, flows to a vessel 37 and is then supplied to another centrifuge 39 discharging the oil through a line 46 and the aqueous liquid through a line 48 to a tank 49. Using the warming treatment, the cream is delivered from line 21 through a pipe 44 to a warming apparatus 41, such as a heated coil 40, and warmed therein to the above temperatures.  After the enzymatic action, the cream, now broken, is passed to the centrifuge 39 as before. The pressed meat from the press 14 may be passed to a drier 52 and then to a screw press 54 to expel residual oil.  The latter is collected in a storage tank 60 which also receives the oil from line 46.

Abstract: 1,106,224. Carbon dioxide generator. G. M. RIEDL; E. M. REYNER and S. R. FREEDE. 18 March, 1965 [19 March, 1964], No. 11436/65. Heading B1X. [Also in Division F1] A pressurized dispensing container (see Division Fl) encloses a chemical gas generator which is responsive to decreasing pressure in the container to generate gas. In Fig. 1, gas generator 42 is mounted on an insulating layer 13 within a flexible bag 40, and comprises a chamber 44, e.g. for aqueous or anhydrous citric acid, connected by either pipe 46 having a check valve 50, or a capillary tube. (Fig. 4, n o t shown), to a chamber 54, e.g. for sodium bicarbonate. When the container pressure falls, acid rises from chamber 44 to chamber 54. producing CO 2  which inflates bag 40 to maintain the pressure in the container. Valve 50 prevents flow of acid when the container is inverted. In Fig. 3, a coiled or folded flexible bag 140 has its inner coils lined with sodium bicarbonate, and its outer coils filled with acid via a valve 143. Fall in container pressure causes expansion of the bag to expose the bicarbonate to the acid, thereby inflating the bag with CO 2 . The bag may be of plastics, metal foil or treated fabric. Other examples of acid are tartaric, hydrochloric and sulphuric.

Patent GB-671608-A (GB)
Title: Improvements in or relating to the synthesis of alcohols
IPC: C07C29/14
Filed: 1950-05-09
Abstract: In a process of carbonylation of olefinic compounds with carbon monoxide and hydrogen to form an aldehyde, decomposition of dissolved catalyst metal carbonyl in a catalyst decomposition zone, and hydrogenation to alcohol in a catalytic hydrogenation zone, water is added to said hydrogenation zone either by injection into the feed or separate injection into the hydrogenator.  Alcohol selectivity is increased, and higher hydrogenation temperatures are possible.  The feed to the catalyst decomposition zone is preferably dried to a water content of less than 1, preferably about 0.5 per cent, and the catalyst-free product is hydrogenated after adding water which may be as much as 50 but is preferably 1-10 per cent.  A sulphactive catalyst such as molybdenum sulphide on activated carbon may be used. It is desirable that the water is substantially completely in the vapour phase.  The carbonylation may be effective with a cobalt soap as catalyst in a concentration of 0.1-5 per cent of the olefin. After high pressure gas separation, and drying, catalyst is decomposed by heating at about 300-400 DEG  F., CO being removed in a stripping gas, and metal by filtering.  Hydrogenation is then effected at 300-600 DEG  F. and 2500-4500 p.s.i.g., with continuous or intermittent injection of water.  Examples illustrate the effect of removing water from the decobalter feed, and of adding water in the hydrogenation of a C8 aldehyde.

A variable inductor comprises one or more coils 13, disposed in a magnetic circuit member 4 which also includes a permanent magnet 1 and an element, which may be the magnet, which is movable to vary the density of flux in the magnetic circuit. The magnet is mounted on a spindle 5 which is pressed by a spring 11 compressed between the magnet 1 and a brass strip 10 against a bearing member 8 in a brass strip 9. The strips 8, 9 join the two ends 2, 3 of member 4 between which the magnet 1 lies. A magnetic screen 12 surrounding magnet 1 provides a path for the leakage flux when the magnet is rotated from the position shown of minimum inductance. The coils 13 are flattened toroids surrounding cylindrical ferrite cores. To avoid the need for screen 12, ends 2, 3 may surround the magnet, Fig. 4 (not shown). In a modification, the magnet 1 is stationary and the movable element is a magnetic member which rotates between a position in which it completes the magnetic circuit through the coils and a position in which the flux is diverted to a shunt path, Fig. 5 (not shown).

Abstract: 702,048. Knitting. WOLSEY, Ltd. Feb. 19, 1951 [May 10, 1950], No. 11591/50. Class 74 (2) In a circularly knit sock, the heel pouch, knitted by reciprocation whilst the instep needles are inactive, has upper suture lines 11 diverging downwardly from the top of the heel to the point 13 thereof and intermediate suture lines 12 extending rearwardly from the heel point, and is of plain fabric incorporating a heel yarn of material different from the yarn of which the leg is knitted and extending to and fro between the upper suture lines and between the intermediate suture lines. When knitting has progressed to line 10, 11, 15, the instep needles and all the heel needles, excepting a small central group thereof CHN having extrashort butts, are moved to inactive, loop-holding level. Reciprocatory knitting is then begun and nylon splicing yarn introduced, needles being progressively brought down from the inactive level and added to the ends of the inactive group until all heel needles are knitting, so producing downwardly divergent upper suture lines 11. Narrowing and widening are then carried out to produce intermediate suture lines 12 and, when all heel needles are again active, the instep needles are re-introduced and circular knitting resumed along the line 14, 15. When narrowing is by two up-pickers which operate alternately in successive swings, each to pick up the first needle reaching it and widening is by at least one down-picker operating in each swing to pick down the first two inactive needles reaching it, the up-pickers . may be rendered active just before the points 13 are reached, in the production of the sutures 11, to obviate the formation of eyelet holes at those points. The splicing yarn may be continued along the foot bottom and knitted into the toe, which may be formed by narrowing and widening. A superposed needle cylinder machine may be used and the leg and instep may be of rib fabric.
