Title: Interesterification process for fatty glycerides
IPC: C11C3/10
Filed: 1961-12-01
Abstract: Fatty glyceride esters containing not more than 0.1% free fatty acid are randomly interesterified by (a) forming a dispersion in the ester of 0.02-0.08%, by weight of the ester, of alkali metal, preferably sodium, hydroxide in the form of a 1-12% aqueous solution containing also at least 0.1%, but preferably not more than 0.3% glycerol, while maintaining the temperature high enough to melt all solids present but not so high as to flash off the glycerol, i.e. generally not above 160 DEG  C.; (b) maintaining the temperature at least 120 DEG C. but below that at which the glycerol will boil off, and usually not above 200 DEG  C., until the desired degree of molecular rearrangement has been attained; (c) destroying the hydroxide catalyst by addition of an edible acidic material, suitably citric or phosphoric acid, capable of splitting alkali metal soaps, in an amount of 1-5 equivalents of the alkali metal hydroxide present, but preferably in an amount no greater than that which would produce a free fatty acid content in the rearranged esters of 0.7%; and (d) removing the oil-insoluble material thereby formed.  If required, steps (a) and/or (b) may be carried out under reduced pressure.  If the glycerides to be randomized contain more than 0.1% free fatty acid, they may be pretreated to reduce the level below 0.1% by adding sufficient aqueous alkali metal hydroxide solution containing 1-12% hydroxide, and thereafter removing water by heating under vacuum. Glycerides suitable for interesterification comprises mixture of soyabean oil with tallow or lard, and of palm oil and coconut oil. The free fatty acid present in the product may subsequently be removed by a conventional deodorization process.  Specification 802,129 is referred to.

In a system for space-heating or cooling, or for heating or cooling an area such as a wall, floor or ceiling, or for heating an area such as an aeroplane runway, road or football pitch, by circulation of air, the air is forced by a fan 4 through a ducting arrangement comprising two spaced side ducts 1 interconnected by smaller section cross ducts 3 and by a cross-duct 2 similar in area to the ducts 1. The ducting is normally arranged below the surface of the area to be heated or cooled thereby as shown in Fig. 2. In an installation described, electric heating elements 5 are arranged in the duct 2. Alternatively, the ducting may contain means for cooling the air. When the ducting is incorporated in the wall, floor or ceiling of a room, the room air may be circulated through the ducting by way of branch ducts 8, 9, 10 in which control dampers (not shown) are arranged. Fresh air may be introduced into the system through the branch ducts. The system may include means for filtering and/or drying the air. The air ducts may be incorporated in or cast in concrete or the like, sufficiently massive to serve as a heat storage medium. Alternatively, for quick response heating the ducts are arranged near the floor or like surface to be heated.

The movable member may be a piston as shown or a diaphragm. In use, liquid under pressure is introduced into chamber 14 to move piston 13 against stop 16 and then gas at a lower pressure is introduced into chamber 11 the piston 13 remaining against the stop 16. Liquid is then allowed to escape from chamber 14 via valve 32a at a predetermined constant rate, and the piston 13 moves to the right causing the pressure in chamber 11 to decrease at a predetermined constant rate. The device may be used to test the sensor 10 of a line break control on a pipe-line which is adapted to close down the pipe-line if the pressure in the pipe-line falls at a predetermined rate. The gas in chamber 11 may be gas from the pipe-line or nitrogen from a cylinder 21. The hydraulic liquid may be a glycal-water mixture, and the pump may be hand or motor driven. The device may be portable or permanently installed in a line break control.

Abstract: 981, 550. Digital data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 21, 1963 [Dec. 24, 1962], No. 45922/63. Heading G4C. A system for correcting the reading of a block of data bytes from a record, e.g. a magnetic tape, which block has a parity check bit for each row and for each column, includes means for checking the parity of each row and each column, means to cause the record to be re-read and means to correct an erroneous bit if only one row and one column were in error on the previous reading. If two or more errors are simultaneously detected tape is re-read up to say 100 times to see if all but one of the errors can be removed by the cleanint effect of the tape read head. After 100 unsuccessful re-readings the tape drive is stopped by a counter or by a sub-routine of the computer for which the tape is being read. If only one row and one column are in error it is assumed that the error is due to a drop out and that a "one" bit is missing this "one" bit is inserted at an OR gate during the re-read cycle. Additional circuits selected by manually operated switches are arranged to prevent a correction if either further errors are detected during the re-reading or the error position shifts. Marginal dropouts are recovered as described in Specification 875,694.
