Title: Treatment of esters
Inventor: FORD IAN ALASTAIR MONCRIEFF
IPC: C07C67/48
Filed: 1951-02-23
Abstract: Saturated complex esters derived from aliphatic glycols or polyglycols, dibasic aliphatic acids and monobasic aliphatic acids or monohydric aliphatic alcohols are washed with aqueous alkali in the presence of methylol.  The complex esters may be represented by the general formula A(OOC-B-COOG)nOOC-B-COOA or A(COOG-OOCB)n-COOG-COOA in which B and G represent dibasic aliphatic acid and glycol residues respectively, n is an integer preferably less than 4 and A is a monofunctional aliphatic group.  The preferred esters are those of formula AOOC-B-COO-G-OOC-B-COOA in which A is a monohydric alcohol residue, B is a dibasic aliphatic acid residue and G a glycol or polyglycol residue.  Preferred starting materials from which the esters are derived are C8 and C9 alcohols, preferably branched-chain, sebacic and adipic acids, and polyethylene glycols up to and including hexa-ethylene glycol.  The preparation of the esters may be carried out by esterification in one or more stages, e.g. by the simultaneous reaction of stoichiometric proportions of the reactants, or by the preparation of the glycol half ester or the alcohol half ester and subsequent reaction with the alcohol or glycol respectively.  Conventional esterification catalysts, such as toluene sulphonic acid or sodium bisulphate may be used. Preferably the washing with aqueous alkali in the presence of methylol is followed by washing with water in one or more stages, at least one of these stages and preferably all of them being carried out in the presence of methylol.  The preferred range of proportion of methylol is 3/4 to 2 volume to one volume of ester.  Commercial methylol, containing about 5 per cent of methanol, may be used.  The washing is conveniently carried out between 10 DEG  and 30 DEG  C.  The preferred alkali is sodium carbonate and concentrations of 7.5 to 10 per cent (w./v.) are satisfactory. Preferably before the alkali washing the esters are stripped of volatile products by heating under vacuum.  In the example a complex ester prepared from sebacic acid, commercial "polyglycol 200" and 2-ethyl hexanol is heated under vacuum to remove volatile contaminants, heated with aqueous sodium carbonate in the presence of methylol and finally washed with water in two stages.  Specifications 666,697, 683,803, 687,346, [Group III], 687,347 and 687,348 are referred to.

Abstract: 920,461. Fishing reels. P. S. BRULHART. Feb. 8, 1961 [Feb. 8, 1960], No. 4678/61. Class 48. A fishing reel comprises a pick-up 11 rigidly mounted on a bell-shaped winding member 10 coupled by an adjustable friction clutch 12, 13 to the outer end of a rotatable driving spindle 7, a fixed spool 18, and an eccentric system for imparting a relative reciprocating motion between the winding member 10 and the spool 18 during winding in and for causing the pickup to be located clear of the line during casting. The eccentric system comprises a pin 23 secured to an extension 20 of a carrier 19 for the spool and engaged in a groove 24, 24<SP>1</SP>, Fig. 2, in a gear-wheel 5 rotated by a crank 3. On rotation of the crank in the winding-in direction the pin follows the closed part 24 of the groove to reciprocate the spool, and on rotation in the opposite direction the pin follows the other part 24<SP>1</SP> of the groove until arrested by the termination thereof. In this condition the spool occupies a position lower than its lowest position during reciprocation. The driving spindle 7 has a pinion 6 engaging the gear-wheel 5 and mounted in a thrust bearing 8. The friction clutch connecting the spindle 7 to the winding member 10 comprises a disc on the spindle 7 and two discs on the winding member 10. The frictional force is adjusted by a knob 16 having an inclined contact surface engaging pins 15 pressing an annular spring 14 against the discs. The crank 3 is secured to its shaft 2 by a ring 40 screwed on to the shaft. When the ring is unscrewed the crank can be turned into the position shown in dash-dotted lines for transporting. A one-way ratchet clutch 41 for the crank-shaft 2 can be retracted against the action of a spring by rotating a handle through 90 degrees. In a further embodiment the spool does not reciprocate but instead the winding member rotates and reciprocates. The spindle on which the winding member is mounted is so arranged in a pinion engaging the driving gear that it rotates therewith and slides therein. The spindle is rotatably but non-slidably mounted in a slidable block having a pin engaging a groove in the driving gear, the groove having a continuous part and a terminating part. The end of the terminating part is farther from the centre of the gear-wheel than any other part of the groove to locate the winding member at a high position clear of the line.

A frequency synthesizer receives as input a signal variable in 100 c/s. steps from 3-4 Mc/s. supplied by a unit of the type described in Specification 942,337 and provides an output signal variable in 100 c/s. steps from 1À6-31À6 Mc/s. The output of a final oscillator operating in the range 126À6-156À6 Mc/s. is mixed with the output of a fixed 125 Mc/s. oscillator to provide output signals in the required range and is also applied to a balanced modulator in which it is mixed with a signal at either 105, 115 or 125 Mc/s. in dependence on the 10 Mc/s. decade of the output frequency and derived from the 125 Mc/s. oscillator and a high stability 10 Mc/s. source. The output from the balanced mixer in range 21À6-31À6 Mc/s. is applied via a tuned filter to a mixer in which it is mixed with one of ten highly stable signals spaced 1 Mc/s. apart in the range 18-27 Mc/s. The tuning of the filter and the required signal are selected in dependence on the 1 Mc/s. decade of the final frequency. The mixer output in range 3À6-4À6 Mc/s. is applied with the input signal in the range 3-4 Mc/s. to a second mixer to provide a 600 kc/s. signal which is compared in a phase comparator with a 600 kc/s. signal derived from a stable source. The output of the comparator provides a signal to control the frequency of the final oscillator.
