[Also in Divisions A2 and C5] A triglyceride composition is prepared by fractionally distilling a randomly interesterified lauric acid oil having an iodine value of less than 5 at an absolute pressure below 15 mm. Hg to obtain a distillate and a residue fraction. In place of the said oil, a lauric acid oil co-randomly interesterified with up to 15% by weight of a non-lauric acid oil containing predominantly triglycerides of C 16  and higher fatty acids, may be used. The lauric acid oil and the non-lauric acid oil are preferably hydrogenated to an iodine value of less than 5 before interesterification. Suitable lauric acid oils are coconut, palm kernel, babassu, tucum, murumuru or mixtures thereof. The preferred non-lauric acid oil is rapeseed oil. In an example, coconut oil is hydrogenated then randomly interesterified by heating the oil with glycerine, with NaOH as catalyst, and distilled at 280.. 290‹ C. to give a desirable residue.

Title: Data transfer system
IPC: G06F3/06
Filed: 1963-10-16
Abstract: 1,018,762. Transferring data. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 16, 1963 [Oct. 30, 1962], No. 40767/63. Heading G4C. In a system for transferring a sequence of data bytes (each being bits in parallel), a normal byte initiates a cycle to cause its own transfer and also initiates, after a delay, a next-byte signal which enables the transfer of the next byte if this has abnormally low signal levels due, for example, to magnetic tape dropout. In Fig. 1 (not shown), a byte read from a magnetic tape (NRZI) is base clipped at a low level by low sensing units and at a high level by high sensing units, the clipped signals being stored in low and high registers respectively. In the absence of dropout, the high register will be more reliable than the low register because the high sensing units will pass less noise than the low. On the other hand, with dropout, the low register will be more reliable because low-signallevel dropped-out bits will get through the low sensing units but not the high sensing units. The first byte of the sequence to be transferred is a " start-block " byte having sufficient 1's for dropout of all of them to be extremely unlikely. When this byte (or rather the first undroppedout 1 bit thereof, in case of skew) arrives in the high register, a signal RC-O (not shown) is provided to actuate a delay device 31 (not shown) which after a delay of about half a bit period produces a signal RC-7 (not shown). This signal causes a vertical redundancy check (VRC) unit to perform a parity check on the bits in the high register. If there is a parity error, indicating dropout, the contents of the low register are read into an output register. If there is no parity error, the high register is read into the output register. Signal RC-7 (not shown) also sets a trigger 33 (not shown) to actuate a second delay device which after a delay of about half a bit period sets a trigger 35 (not shown). This trigger produces a next-byte signal level at one input of an AND-gate 28 (not shown). When the next byte arrives in the low and high registers, exclusive OR circuits compare corresponding bits in the two registers and any non-equality (indicating possible dropout) opens AND-gate 28 (not shown) to the next-byte signal thus setting a trigger to produce a substitute signal to actuate delay device 31 (not shown). To avoid possible actuation of delay device 31 (not shown) by noise in the low register during the last next-byte signal produced during the block transfer, the last byte of the block may be an " end-of-block " byte to disable the delay device by means not described. The comparison exclusive OR circuits may be replaced by AND gates, the high register input to each being via an inverter.

Abstract: 961,760. Electric selective signalling. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 30, 1962 [Nov. 2, 1961], No. 41013/62. Heading G4H. The duration of a pulse is encoded as a sequence of clock pulse, by a device not requiring the arrival of the pulse to be synchronised with the clock pulse generator, by applying to to two identical threshold devices 1, 3 (e.g. Schmitt triggers) the outputs of which control identical AND-gates 2, 4 to which are applied clock-pulses P 1 , the outputs of gates 2, 4 each being applied to an AND- gate 5 nad to an OR-gate 6, the outputs of which feed the first stages of shift registers 8, 9 respectively; the information stored in the first stage of register 8 being shifted to the second stage between adjacent clock pulses P 1 ; and means being provided for clearing to "ZERO", during the period between adjacent clock pulses,the "ONE" stored in the second register 9 during the previous period provided AND-gate 5 has stored a "ONE" in register 9 during either the same (first-said) period or one of the two preceding periods, but otherwise to transmit said "ONE" in register 9 to actuate an alarm device 12. Registers 8, 9 have three and two stages respectively and shifting is accomplished by clock pulses P 2 , P 3  respectively, of the same frequency as pulses P 1  but lagging in phase, P 3  later than P 2  later than P 1 . The shifting of a "ONE" in register 8 clears the second stage of register 9 to "ZERO". The alarm 12 is actuated if a "ONE" is present in the second stage of register 9 when a pulse P 3  occurs, i.e. if there were no "ONES" in register 8 on occurrence of the previous P 2  pulse. The system enables malfunctioning to be indicated without the alarm being actuated when the threshold levels of devices 1, 3 are (only) slightly different and a P 1  pulse arrives at gates 2, 4 when the input pulse signal level lies between the threshold levels. The sequence of pulses representing the input duration is fed to an unspecified unit 7.
