Title: Improvements in control systems of textile twisting machines for the production of fancy effects in yarn
IPC: D01H5/36
Filed: 1963-08-07
Abstract: 970, 511. Producing fancy yarns. E. HAMEL. Aug. 7,1963 [Aug. 8,1962], No. 31075/63. Heading D1D. In making fancy yarns by changing for a selected time the rate at which yarn is supplied to a twisting apparatus by cams on a chain or disc which operate on an electro-mechanical or electromagnetic clutch for adjusting the speed of the delivery-means, a timing-device is operated simultaneously with the operation of the clutch means, is driven at a speed proportional to that at which the delivery means is driven, and, at the end of a predetermined period operates a switch to deenergize the adjusting-means. One part 2 of an electromagnetic clutch is keyed to a shaft 1 on which a yarn-delivery roller is mounted. The other part 3 is loose on the shaft and carries a pinion 4 meshing with a pinion 5 loose on a shaft 6. An arm 10 loose on shaft 6 carries a switch 11 and a pin 12 which can engage a selected one of a number of holes in a fixed disc 14. The pinion 5 carries a finger 7 which with the clutch-parts disengaged, is caused by a spring 8 to be in contact with a stop 9. When the speed of the deliveryroller is to be changed the control-cam provides an electric impulse which closes the circuit of a speed-adjusting clutch, and of the clutch 2, 3. The finger 7 engages the switch 11 after an interval determined by the setting of the arm 10 relative to the disc 14; the switch 11 disengages the two clutches, so that the delivery roller reverts to normal speed, and the drive to the pinion 5 is interrupted. During the rotation of the pinion 5, the spring 8 is tensioned so that when the clutch 2, 3 is separated it back-rotates the pinion 5 to bring the finger 7 against the stop 9. In another form the timer comprises a perforated disc continuously rotating with the shaft of the delivery-roll. When the speed of the latter is charged a lamp is switched on to give light-impulses through the holes in the disc to operate an impulse-counter through a light-sensitive cell. When a selected number of impulses have been counted, the circuits for the clutch controlling the delivery roller and lamp are interrupted.

Title: Manufacture of tetrahydrobenzyl tetrahydrobenzoate and pimelic acid therefrom
Inventor: HAWKINS EDWIN GEORGE EDWARD
IPC: C07C51/295
Filed: 1950-12-23
Abstract: D 3 - Tetrahydrobenzyl D 3 - tetrahydrobenzoate is prepared by condensing D 3-tetrahydrobenzaldehyde with itself in the presence of an aluminium or magnesium alkoxide, generally at temperatures between 0 DEG  and 110 DEG  C.  The reaction may be carried out batchwise or continuously and, if desired, in the presence of an inert organic solvent such as esters, ethers or hydrocarbons, D 3-tetrahydrobenzyl alcohol or, preferably, the ester product itself.  The specified catalysts are the ethoxides, isopropoxides and isobutoxides.  The aldehyde is preferably free from acidic impurities.  The ester may be recovered by distillation after neutralization of the catalyst. Hydrolysis of the ester, separated or not from the condensation mixture, yields D 3-tetrahydrobenzyl alcohol and D 3-tetrahydrobenzoic acid or, under alkaline conditions, its salt. The free acid or its salt, if desired after partial or complete separation from the hydrolysis mixture, may be converted into pimelic acid by pyrolysis in the presence of aqueous alkali at temperatures of 250 DEG  to 400 DEG  C. in batchwise or continuous fashion using, for example, an autoclave or coil reactor. Suitably, a slight excess of alkali over the theoretical amount for salt formation is used. Sodium and potassium hydroxides are preferred.  Conveniently the hydrolysis is effected using two mols. of alkali per mol. of ester and after refluxing and separating the liberated alcohol, pimelic acid is formed on pyrolysing the residue and acidifying.  The recovered tetrahydrobenzyl alcohol may be converted to the aldehyde for further condensation by oxidation, e.g. at 350-500 DEG  C. in vapour phase over a silver or other oxidation catalyst or by dehydrogenation, e.g. in the presence of a copper chromite catalyst. Unchanged aldehyde allowed to remain in the condensation product is stated to be converted into pimelic acid in the pyrolysis state. Examples are given.
