The esterification may be carried out in the presence of a reaction promoter and in an inert atmosphere. The first stage of the stripping process may be carried out under a vacuum of from 25-50 cm. of mercury and the second stage may be carried out under a vacuum in excess of 60 cm. of mercury. During the course of the reaction, fatty acids distilled off may be replaced by supplying the reactor with fatty acids of approximately the same composition, some or all of which may be from the distillate recoverable during the process.

Title: Apparatus for generating an electrical output signal of  variable frequency
IPC: H03L7/22
Filed: 1971-11-13
Abstract: 1396708 Automatic frequency control SOLARTRON ELECTRONIC GROUP Ltd 8 Nov 1972 [13 Nov 1971] 52844/71 Heading H3A Variable frequency generation apparatus comprises': a first variable frequency generator 10; a second variable frequency generator 26 producing a frequency lower than that of the first; a circuit 20 receiving the first and second frequencies: and producing an output frequency equal to the. difference between the first and a harmonic of the second; a phase sensitive detector 34 for comparing this output frequency with a further frequency #m to produce a control signal dependent on the difference which adjusts the first generator frequency to phase lock it to the other two; means RV1 for varying the second generator frequency to produce a continuously variable output frequency from the first generator; and means 51 for varying the second oscillator frequency if the frequency difference between #m and the output from circuit 20 exceeds a predetermined value. As described, the output from circuit 20, which is a sampling circuit, is fed to a band pass filter centred on #m. If the signal goes out of the passband, the output from the filter enables gate 70 to pass clock pulses from oscillator 88 to a counter 76 and D/A converter which produce a sweep voltage for a varactor controlled crystal oscillator 46. The output from this oscillator is mixed in 52 with the output from another varactor controlled crystal oscillator 47 which is manually adjusted by RV1 to give fine output frequency -control. The difference frequency output from mixer 52 is the second generator frequency. Coarse manual frequency control is effected directly on generator 10 by control 14 which is ganged with a switch 37 to disconnect frequency #m. During this condition, a further phase comparator 41 provides a "loss of synchronization" signal which enables gate 70 if a suitable signal is provided from filter 20. Further adjustment to the output frequency is by variable dividers 98, or alternatively, Fig. 2 (not shown) generator 10 may comprise a number of interchangeable oscillators. The output signals may be frequency modulated by deriving #m from a frequency modulated oscillator 92, or may be amplitude modulated by modulator 106.

Spindle 26 is sealed by packing rings 66, 68, 70 and is connected to ball B by a connection (Figs. 8 and 9, not shown) which provides limited universal movement between the ball and spindle. The upper end of the spindle is connected by pin 76 to a drum C carrying an actuating cord 28. A stop-pin 122 on the drum co-operates with an arcuate slot 120 (Fig. 1, not shown) to limit rotation of the spindle to the open and shut positions of the ball.
