Abstract: 1,051,089. Sulpholane purification. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. July 5, 1965, No. 28295/65. Heading C2C. A sulpholane containing sulpholene, particularly one produced by the hydrogenation of a 3-sulpholene, especially in the presence of an aliphatic alcohol, as hereafter defined, is purified, by a, process which comprises contacting with an aliphatic alcohol, in the presence of an amount of a basic substance, especially with an alkali metal, e.g. Na, or alkaline earth metal hydroxide, such that the pH of the sulpholane/ alcohol mixture when diluted with an equal volume of water is at least 8, and preferably 10 to 14, whereby the sulpholene in said mixture is converted to the sulpholanyl ether of said alcohol, and thereafter recovering purified sulpholane from the resulting mixture by distillation. Aliphatic alcohol is defined as a monohydric alcohol, the sulpholanyl ether of which is substantially non-volatile or has a boiling-point sufficiently different from the boiling point of the sulpholane from which it is to be separated. The example describes the purification of sulpholane in a 40% by weight concentration in isopropanol as obtained by the hydrogenation of 3-sulpholene with Raney Ni catalyst, followed by the destruction of the free sulphur dioxide with hydrogen peroxide and neutralization of the sulphur trioxide with aqueous sodium hydroxide. Additional sodium hydroxide was added to effect the sulpholene conversion after which the products were separated by distillation.

Abstract: 1,234,549. Ink-ribbon mechanisms. INTERNATIONAL COMPUTERS Ltd. 28 Jan., 1970, No. 4056/70. Heading B6F. [Also in Division H2] An arrangement for driving an inked ribbon 1 in a typewriter comprises two shaded pole induction motors 4,5 (see Division H2) driving a ribbon winding up reel and a paying out reel, the motors being arranged to rotate in the same direction with that one driving the winding up reel delivering a higher torque than the other one. Rivets 53 (only one shown) near the opposite ends of the ribbon operate switches 35 and 36 respectively to alter the energization of the motors so that they reverse their rotation and that one driving the winding up reel always delivers the higher torque. Upon de-energization of the motors, the rotors are braked to maintain tension in the ribbon. In the arrangement shown, on re-energization of the motors the ribbon is always moved from left to right (as clepicted in the drawing) but by controlling the system with a toggle action contact operated by the rivets 53, it is possible to ensure movement of the ribbon in a given direction on re-energizing the motors after a period of standstill.

Rotatable ball plug valve comprises a ball valve member 5 supported against the downstream slat 7 by a spring 9. The valve member has a key and slot connection with an operating stem 10 which allows it to take up its position on the downstream seat. The valve member may be clear of an upstream seat 8 excepting under reversed pressure conditions. The stem 10 is located axially, e.g. by a sleeve as shown between the handle 12 and body 1, so that it cannot push downwardly and displace the valve member. A stop plate 16 on the key end of the stem co-operates with an abutment 17 on the body and limits the rotation to 90 degrees. The stem may seat conically at 26 in a bonnet 21 to provide frictional resistance preventing accidental rotation of the valve member. The stem is sealed by an 0-ring 22. In another embodiment a ring (41), Figs. 6 and 7 (not shown), seating on the ball constitutes an abutment for the spring.

Powder is discharged from a container 1 by compressed air supplied through porous screens 10, 11, the pressure in the container being maintained at a constant value irrespective of the level of the powder in the container. A bypass pipe 21, extending between the top of the container and an ejector 22 in the outlet pipe 23, is provided with a valve 24 controlled by a diaphragm unit 25 connected to a regulator 27 coupled to a pressure sensor 28. In operation, with the material inlet valve 6 closed and the compressed air control valve 15 open, the by-pass valve 24 is closed. When the pressure in the container reaches a predetermined value, the regulator 27 causes the outlet valve 19 to open and controls the by-pass valve 24 so as to maintain the pressure in the container substantially constant. In the event of a blockage in the delivery pipe 23, the container pressure increases and the regulator causes the outlet valve 19 to close and the by-pass valve 24 to open fully. In a modification, the by-pass pipe 21 is replaced by a by-pass pipe 211 extending between the compressed air inlet pipe 14 and the ejector 22 and provided with a control valve 241.

As shown, rotor 17 completes one revolution in 24 hours and cams 60, 60<SP>1</SP> are arranged (Fig. 4, not shown) to change-over a contact 140 twice in each revolution of rotor 17, the angular steps of shaft 20 being located by a detent 42 and plate 41 corresponding in shape to the star wheels 51, 52. The wheel 53 is freely rotatable on shaft 20 but axially secured thereon. It has seven points and is thus rotated once per week. A fixed plate 133 engages the face-cam portion 530 such that when it encounters a cam rise the wheel 53 and therefore the shaft 20 is shifted axially against the action of a spring 30, thus bringing wheels 51, 52 respectively into alignment with the alternative fingers 1711, 172<SP>1</SP>.

A dial 170 is provided on rotor 17 for time-setting of fingers 171 to 173. The programme may be altered by rearrangement of cam members on wheel 53, or by changing the wheel 53. A programme change may be provided by manually stepping wheel 53.
