Title: Preparation of oxygenated compounds by carbonylation of olefins
IPC: C07C31/13
Filed: 1959-12-28
Abstract: Oxygenated compounds are prepared by the carbonylation of olefines at elevated temperature and pressure in the presence of a carbonylation catalyst and of an acetalisation agent consisting of an olefinic oxide or a polyhydric alcohol, the acetal which is formed being withdrawn from the carbonylation zone.  Suitable olefines are, for example, propylene, pentene-1, hexene-1, octene-1, cyclohexene, nonene and tetrapropylene.  The preferred conditions for carrying out the process are a temperature of 265-320 DEG F. and a pressure of 3000-4000 psig.  The products are mainly acetals and alcohols.  The acetals formed may be hydrolysed to give the corresponding aldehydes which may be hydrogenated or oxidised by known methods to give alcohols or acids respectively. Suitable acetalisation agents are, for example, ethylene glycol, propylene glycol-1.2, propylene glycol1.3, butane-diol-1.4, glycerin, ethylene oxide and propylene oxide.  It is desirable that all reactants should be substantially free of water.  In the examples (a) cyclohexene is carbonylated in the presence of ethylene glycol to give the ethylene acetal of hexahydrobenzaldehyde which is subsequently hydrolysed to give hexahydrobenzaldehyde and (b) butene-1 is carbonylated in the presence of ethylene glycol to give the ethylene acetal of a C5 aldehyde which is subsequently hydrolysed to give a mixture of n-valeraldehyde and 2-methyl butylaldehyde.

Title: Improvements in ring and traveller mounting arrangements for textile machines
Inventor: COLE STANLEY LEWIS
IPC: D01H7/56
Filed: 1963-11-20
Abstract: In a ring-and-traveller arrangement for a spinning-frame, the ring is rotatably mounted on a support adapted to provide a cushion of air between the ring and the support on which the ring can rotate, the traveller engaging the ring and being freely rotatable thereon.  In Fig. 2, (not shown) the ring-holder has an inclined bearing-surface 19 to receive a corresponding surface of a ring 14.  The holder has an internal passage 22 closed by an insert 23 which communicates by ducts 20 with eight exits 21, so that air under pressure fed into the passage 22 forms a cushion to support the ring.  The skirt portion 12 of the ring is of smaller diameter than the support and may be fitted with inclined blades. The drag of the traveller acting on the ring-portion 13 causes the ring to rotate and air impinging on the blades imparts an additional driving thrust to the ring.  When high operating speeds are employed, the supply of air may be reduced or cut off when the ring reaches a desired speed.  To reduce the speed of the ring, the latter may be provided with holes, to give an aero-dynamic braking effect, or friction or eddy-current braking-devices which may be variable according to the weight of the traveller.  In Fig. 3, (not shown) the ring comprises a skirt 26 running on rings 29, 30 clamped together at 33.  These have ducts 37, 39 with threaded and bored plugs 34 leaving clearances 27, 28 providing an air-cushion when air under pressure is introduced into the ducts 37, 38.

In Fig. 1 light from source 1 passes to detector 9 via a wavelength selector 2, a fixed linear polarizer 3, the rotating modulator 4, sample 6, a quarter wave plate 8 and the rotatable analyzer 7. In use a motor 5 drives the modulator at frequency f, and an optical pick-up produces reference signals indicative of this rotation.

The detector output is amplified and fed to a phase sensitive motor 11 which adjusts the analyzer to remove phase differences between the detector signal and the pick-up signal. The necessary analyzer rotation is doubled and is displayed at 12 to represent the sample's phase lag.
