Title: Process for the production of alcohols
IPC: C07C29/72
Filed: 1955-07-28
Abstract: Primary alcohols are obtained by oxidizing an aluminium hydrocarbon containing aluminium bound to the group -CH2-CHR1R11, in which R1 and R11 are hydrogen or hydrocarbon radicals, with molecular oxygen and decomposing the aluminium alcoholate so formed.  The oxidation may be carried out at a temperature between 0 DEG  and 100 DEG  C., preferably between 30 DEG  and 60 DEG  C.  In the examples: (a) nitrogen is bubbled through tri-n-octyl aluminium in a recycle apparatus and at one point in the cycle oxygen is introduced; the aluminium octylate obtained is decomposed by the addition of water and heating and the octyl alcohol formed is distilled off; (b) aluminium tri-(phenyl-ethyl) is treated as in (a) to give phenyl ethyl alcohol; (c) a mixture of aluminium alkyls obtained by cracking higher Fischer-Tropsch paraffins and treating the product with tri-isobutyl aluminium is oxidized and the alcoholates formed are then hydrolysed as in (a) to give a mixture of primary alcohols; (d) a higher aluminium alkyl is obtained by heating triethyl aluminium and ethylene under pressure and the product is treated as in (a) to give normal alcohols containing from 6 to 20 carbon atoms; (e) the aluminium compound obtained from 1-vinyl cyclohexene-(3) is treated as in (a) to give the alcohol of formula <FORM:0804335/IV (b)/1> similarly alcohols of formul  <FORM:0804335/IV (b)/2> are obtained from limonene and camphene respectively; and (f) dimeric dodecene is converted with tri-isobutyl aluminium into the compound <FORM:0804335/IV (b)/3> which is similarly oxidized to the alcohol <FORM:0804335/IV (b)/4> Specifications 713,081, 742,642, 763,824, 770,707, 778,098 and 794,359 are referred to.

Abstract: 614,757. Sorting fruit. TOD, Ltd., J. & J., and TOD, J. R. July 26, 1946, No. 22244. [Class 117] Apparatus for grading fruit according to size comprises a sorting table 2 having an inclined flap 22 hinged thereto on which the fruit to be graded is placed and by which it is transferred to a conveyer 1 travelling below a shaft 14 carrying a plurality of paddle wheels 3. Each of the wheels 3 comprises a disc with a plurality of radial spokes 19, to each of which is affixed a rubber or other resilient blade 20. The height of the paddles above the conveyer 1 on each succeeding wheel decreases from the feed end, whereby the largest fruit is removed by the first paddle wheel and the smaller fruit by succeeding paddle wheels into troughs 4 from which it is delivered into receptacles. The flap 22 is periodically raised and lowered, e.g. by linked to rod 23 pivoted to the flap, to means of a cam-actuated lever-mechanism regulate the supply of fruit to the conveyer 1. The paddle wheels 3 may all have the same radial length and the shaft 14 inclined in an adjustable manner to the belt. A brush may be placed transversely across the conveyer 1 in front of the first or of each of the paddle wheels to roll the calyxes of the fruit over for the period during which the fruit is under the paddle wheel or wheels. The delivery troughs 4 are provided with hinged spring doors 28 to retain the fruit and break its fall on its passage to the receptacle 35. These latter may be placed on a movable spring-controlled platform which, when a predetermined weight of fruit has fallen into the receptacles, moves against the spring forces and releases a trigger to allow the door 28 to close. The platform may also be adjustable in height.

Abstract: 187,763. Cammell, Laird, & Co., Ltd., Allan, J. M., and Carnegie, W. Aug. 23, 1921. Moulds; clamping and guiding moulds; casting processes. - To prevent fracture of clutches, gears, fly-wheels and other castings while cooling in chill moulds having projecting faces, both mould parts are moved in relation to the casting to free it from these faces as soon as a sufficient skin has formed. The mould halves 1, 2 are supported by links 5, 7 eccentrically pivoted to hand-levers 10 or the links 5 may be pivoted directly to a base 6. As the halves are separated by operation of the levers 10, which may be connected to operate simultaneously, the casting is supported clear of the mould by a disc 12 coming in contact with a projecting guide 14. The upper half mould has a flange 11 to guide the parts and the lower half has the vents 20 horizontal to avoid risk of the halves sticking. If the face of the lower half 2 projects at the centre an annular support with downwardly projecting pins to engage the base is employed. If pouring is effected through runners in a core this may be free to move with the casting when the mould half is separated therefrom. Other cores may be similarly arranged if they do not separate from the casting easily.

Abstract: 1306164 Colour television MAGNAVOX CO 12 May 1970 [22 Sept 1969] 22868/70 Heading H4F An arrangement for automatically adjusting the phase angle of the chrominance demodulating signal in a NTSC colour television receiver comprises a null detector 38 which compares the phase distribution of the colour energy in the signal as received from 34 with the phase of the reference signal obtained at 32 from the colour burst and determines a phase correction to be effected at 40 to minimize the energy in the reference phase. This correction is based on the assumption that flesh tones often predominate and that since the I phase (flesh) is at 90 degrees to the reference phase ( - Q), adjustment of the latter to maintain the quadrature arrangement will improve the reproduction of flesh tones. Fig. 3 (not shown) illustrates schematically the generation of a measure of "error" of the reference signal phase by adding the positive peak signal from the Q-axis demodulation output to the inverted negative peak signal, and the use of this in a phase corrector in a feedback loop. In an alternative arrangement (Fig. 4, not shown) the output of the -Q reference generator is passed to a circuit where it is varied between about - Q - 40 and - Q + 40 degrees in sawtooth manner at about 2 c.p.s. and used as demodulating signal in an auxiliary circuit whose output is rectified and smoothed over one frame period. The minimum value of this is detected and used to select the appropriate corrected - Q phase. The arrangement may also be used to adjust the chrominance signal before transmission, using the Q adder to derive the- Q phase reference signal which is then used as above described.
