Abstract: 1,151,939. Diesters; diols. CELANESE CORP. 14 Sept., 1966 [23 Sept., 1965], No. 41075/66. Heading C2C. A mixture of monomeric hydroxy-esters, which can be hydrogenated to a diol mixture over a copper chromite catalyst, is obtained by mixing a stoichiometric excess of a C 4-8  α,#- alkanediol with a mixture of acids obtained by the oxidation of cyclohexane, heating the reaction mixture to reflux while separating water vapour and organic compounds boiling below the b.pt. of the alkane diol and the pressure obtaining, passing the residual mixture through a reaction vessel divided by baffles or packing into a series of successive reaction zones, or through successive reaction vessels, so as to avoid back mixing, while maintaining the reaction zone or zones at an elevated temperature and at a pressure of 50-760 mm. HgA and continuously withdrawing vapours of the water produced and organic compounds boiling below the b.pt. of the alkane diol under the conditions obtaining without permitting the withdrawn vapours to pass through the liquid in any other reaction zone or vessel, and withdrawing the resultant ester mixture after a residence time sufficient to reduce the acid content thereof to below 1À0% by wt. The starting acid mixture contains adipic, glutaric, succinic, hydroxycaproic and formylvaleric acids. By stoichiometric excess is meant one mole of diol per mole carboxylic group in the acid mixture. The final esterification stage is preferably effected at 200-300‹ C. for 2-6 hours. Examples relate to the preparation of 1,6-hexane diol esters and the reduction thereof to 1,4-, 1,5- and 1,6-diols.

The element is formed of at least two flat pieces disposed in contact over substantially the whole of their adjacent surfaces, said pieces being rigidly connected together, each piece having a slot which is not substantially larger than the thickness of the respective piece, the slots being superposed to form the gripping slot. In the embodiment shown, the gripping slot comprises slots 4, 5 in pieces 1, 2 respectively, a wider slot 26 in piece 25 being at least partially closed by parts 27, 28 which may be resiliently separated to allow a conductor to be received in the slot 26 and thence retained therein.

Title: Improvements in or relating to wind control mechanisms for twister and spinning frames

Abstract: 1,112,952. Builder motion. MAREMONT CORPORATION. 7 Oct., 1965 [7 Oct., 1964], No. 42552/65. Heading DID. A builder motion for a spinning &c. frame, comprises a pivoted builder arm and means for oscillating it about its pivot, a member connecting the builder arm to elements which control the formation of the package, the point of attachment of the member being movable for changing the effective length of the builder arm, reversible drive means for reciprocating said joint of attachment, and means mounted separately from the building arm for controlling the reversible drive means. In Fig. 1, a windlass shaft 24 has attached to it a chain 26 connected to the ring rail, a chain 44 attached to a torsion-bar 40 and a chain 32 attached to a drum 34. Also attached to the drum is a chain 36 connected to a pivoted builder arm 28 oscillated by a cam 30. The torsion-bar tends to rotate the windlass shaft to raise the ring-rail, and to keep the arm 28 in contact with the cam; the chain 36 acts through the drum and windlass shaft on the ring-rail so that the rail is lowered when the chain is tightened as the arm 28 is depressed, and is allowed to rise as the chain is slackened. The chain 36 is attached to the builderarm through a nut 52 on a rod 86 which is . pivoted, independently of the arm, at the same point 152 as the arm is pivoted. The rod is drawn upwardly by the pull exerted on the chain by the torsion-bar so that rollers attached to the nut engage the undersurface of the arm. The rod 86 is threaded, and to effect the traverse, the rod is rotated first one way and then the other, and the nut is prevented from rotating so that it moves along the rod. It is arranged that, whatever the posiof the rod, the position of the lowest point of the traverse does not vary; to this end, the undersurface of the arm is an arc of a circle about the axis of the drum 34 as centre. To rotate the rod, a control mechanism is provided in an accessible position, which has provision for adjusting the length of the traverse, if desired when the frame is in operation. This mechanism comprises a reversible motor 134 which is operatively connected to a bevel 88 on the end of the rod. The motor also drives a threaded rod 110 on which moves, as the rod is rotated, a nut having arms 120, 122 carrying adjustable screws 126, 128, which alternately engage a fixed contact 130 to reverse the motor. The apparatus is designed to produce a package having a "partial taper" top. The nut on the rod 110 is arranged to move upwardly as the nut 52 moves outwardly; alternate traverses are of different lengths determined by the positions of screws 128 (for the long stroke) and 126 (for the short stroke). The following are also described: a circuit, Fig. 7 not shown, through which the reversals of the motor are effected, and, Fig. 6 not shown, the arrangement of the nut 86, the associated rollers, the connectionto the chain 36, and the builder arm and its follower 98.

In a refrigerating system comprising a compressor 10 and condenser 12, liquid refrigerant from the condenser is cooled in a heat exchanger 32, passes through a flow restrictor 22 and is then divided into two streams, one of which passes through line 24 to an evaporator 14 and the other of which passes through a by-pass line 30 via the heat exchanger 32 where it evaporates to cool the liquid refrigerant flowing to restrictor 22. Superheated vapour from line 30 is returned to the suction line 16 where it evaporates any liquid leaving evaporator 14 and a valve 36 for regulating the relative proportions of the two streams is provided in line 16 upstream of its connection with line 30. Valve 36 may be adjusted automatically in response to the temperature of the medium being cooled by evaporator 14 and may be located in line 24 downstream of its connection with line 30. Restrictor 22 may be a capillary, fixed orifice or, as shown, a thermostatic expansion valve having its sensing bulb 26 mounted on line 16 downstream of line 30. Water condensed on evaporator 14 is collected in a sump 34 and used to cool exchanger 32. In the embodiment of Fig. 3 (not shown), the heat exchanger (32<SP>1</SP>) comprises a tube (21) through which liquid refrigerant from the condenser is supplied to a chamber (23) and about which is coiled part (31) of the by-pass line (30<SP>1</SP>).
