Title: Improvements in Web Rewinding Machines
Inventor: BREACKER EDWARD ALBERT
IPC: B65H19/22
Filed: 1965-10-13
Abstract: 1,153,633. Winding webs. CHAMBON Ltd. 13 Oct., 1966 [13 Oct., 1965], No. 43398/65. Heading B8B. A web-winding machine comprises an indexable turret 22 adapted to carry individual mandrels from a loading station to a winding station defined by a pair of driven rollers 11, 12. The web, which may be longitudinally slit is advanced to the winding station via a pair of spring loaded accumulating rollers 14, 15; further rollers 16, a web brake 17, 18, and a spring loaded roller 19 which during winding is held-up against the force of the spring by a pawl-and-ratchet mechanism 65, 66. A third driven roller 13 is carried by a fluid-cylinder dampened, parallel-movement, linkage system (Figs. 12,13), to load the web-roll 10 resting on the parallel rollers 11, 12. When the web-roll 10 has reached the required diameter, the feed rollers 11, 12, 13 cease rotating and the turret 22 is indexed through 60 degrees when a locator 20, Fig. 3, of a Geneva device rotates out of a recess 21 in the turret. In so doing, the completed web-roll is removed from the winding station and a new mandrel takes its place. During the 60 degree rotation of the turret, a stationary knife 25 fixed to the machine frame co-operates with one of the six knives 24 fixed to the turret, and severs the web. As this happens, the brake 17, 18 clamps the web, the accumulating rollers 14, 15 rotate to take-up the web still being delivered, and the pawl 66 is tripped by the turret 22 to release the roller 19. Downward movement of the roller 19 until it comes against a stop (not illustrated), draws back the leading or cut edge of the web until it lies just over the drive roller 11. With the turret indexed through 60 degrees, the drive roller 13, which started a downward descent when the wound web-roll was removed, now comes into contact with the mandrel to urge it against the rollers 11, 12. Further, a tuck-in blade 28, driven by an eccentric cam 70 via a lever 71, tucks the leading end of the web into the empty mandrel slot 30. The empty mandrel was correctly orientated to receive the tuck-in blade 28 by a cam surface which is moved into position to engage two diametrically spaced cam follower rollers (not illustrated) carried on one end of the mandrel, as the turret rotates.

Filed: 1972-09-22
Abstract: 1402742 Fluid regulation SIEMENS A G 22 Sept 1972 [23 Sept 1971] 44070/72 Heading G3H [Also in Divisions A5 and F2]  A valve (10) located in a liquid infusion apparatus [see Division A5] provides a liquid flow passage which has a cross-sectional area which varies along its length and is adjustable to expose passage cross-sections corresponding to a small and a larger throughflow quantity. The valve 10 may consist of a piston 25, Fig. 2 which is axially slidable in a cylinder 20 and is circumferentially constrained by a pin 26 engaging in a slot 27. An adjustable nut 30 on a threaded pin 28 at one end of the piston 25 is held in contact with a stop 20a on one end of the cylinder 20 by a compression spring 33 abutting the other end of the cylinder 20 and a cover 31 screwed on a threaded pin 29 at the other end of the piston 25. Flow between unions 23, 24 passes via a space 35 provided by a narrow section of the piston 35 and a tapered passage 36 in the wide section of the piston. Axial displacement of the piston varies the cross-section of the passage. A suitable minimum flow is established by adjustment of the nut 30 and a momentary increase in flow is caused by manual compression of the spring 33 through the cover 31. Alternatively, the valve 10 may comprise two co-axial flat discs 41, 42, Fig. 4, in contact, one having a circumferentially curved tapering groove 49 on its contacting surface, the larger end of the groove communicating with an inlet bore 44. The other disc has an outlet bore 45 at the same radial spacing as the inlet bore 44 and the groove 49. Relative rotational displacement of the discs alters the effective crosssectional area of the groove 49 between the bores 44, 45.

Title: Production of finely divided cuprous oxide
Inventor: CAMPBELL ALASTAIR
IPC: C01G3/02
Filed: 1960-12-22
Abstract: Finely divided cuprous oxide is prepared by adding alkali to cuprous chloride solution at such a rate that the pH and temperature throughout the reaction mixture is maintained at 6,0-9,0 and 30 DEG -90 DEG C. respectively.  The pH is preferably at the higher end of the range when the temperature is at the lower end of the range, and vice versa, e.g. pH 8-9 at 60 DEG C. and pH 6-7 at 90 DEG C.  In one embodiment, cuprous chloride in brine and a 20% sodium hydroxide solution are fed in simultaneously to a precipitation vessel fitted with stirring paddle.  The addition of alkali is controlled by a valve which in turn is controlled by a pH meter, the electrodes of which are immersed in the liquor overflowing from the tank.  The pH is thus maintained at 8,5 and the temperature is maintained at 60 DEG C. by cooling the vessel.  The liquor overflowing from the precipitation vessel collects in a settling tank, where the pH is raised to 9,5 by further addition of alkali to ensure complete conversion of cuprous chloride to cuprous oxide, and prevent formation of cuprous oxychloride.  The precipitated oxide is allowed to settle, and washed with water.  A suspensibility test is performed on a mixture of oxide, sulphite cellulose lye liquor and a wetting agent.  The precipitation vessel is preferably one tenth the size of the settling tank.

Title: Process for the separation of a starting mixture by means of liquid-liquid extraction
IPC: C10G21/28
Filed: 1970-09-24
Abstract: 1321465 Separation of the components of a liquid mixture by solvent extraction and distillation SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 24 Sept 1970 [26 Sept 1969] 45526/70 Heading BIB [Also in Division C5] Following a process wherein a liquid starting mixture is submitted to liquid-liquid extraction with a solvent which boils at a higher temperature than the mixture and in which some of the components of the starting mixture are more readily soluble than others, the less soluble of the dissolved components are removed from the extract phase by distilling it in the presence of a liquid mixture which boils within a lower temperature range than the starting mixture and which contains components which are more readily soluble in the solvent than others. The lower boiling mixture is preferably derived from an original mixture from which the starting mixture is also obtained, e.g. by distillation or extractive distillation. In an example, a mixture of benzene, toluene, xylene, paraffins and naphthenes, obtained by thermal treatment of gasoline, is separated by distillation in column 52 into a C 6 -C 9  fraction boiling in the range 115‹-165‹C, and a C 5 -C 8  fraction boiling in the range 65‹-135‹C. The higher boiling fraction, which contains 91% of aromatics, is passed through line I into column 2 where it is extracted with sulpholane supplied through line 3; and the raffinate, which contains 70.5 paraffins, is discharged through line 4. The extract phase is passed through line 5 into column 6 where it is distilled in the presence of the lower boiling fraction from column 52, additional sulpholane being supplied to column 6 through line 53. Column 6 is operated at a pressure of 1.2 atm. abs. and a top temperature of 113‹C: and the overhead fraction is condensed and passed into the lower section of extraction column 2. The bottoms fraction from column 6 is passed to column 10 where it is stripped with steam supplied through line 12. Sulpholane, withdrawn from the base of column 10, is recycled to column 2; and a sulpholane-rich stream, withdrawn through line 53, is passed to column 6. The overhead fraction obtained from the head of column 10 comprises only aromatic hydrocarbons, and is separated by subsequent distillation into a benzene-, a toluene- and a xylene-fraction.

Abstract: 1,023,608. Recognizing blood samples. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 13, 1964 [Dec. 31, 1963], No. 46266/64. Heading G4R. In apparatus for the recognition of blood samples a search beam from a cathode ray tube scans 72 (Fig. 2, not shown) across a slide until it locates a cell and subsequently scans around the cell 34 (Fig. 5, not shown) to determine its length and shape and then across the cell 108 to determine its colour and internal configuration. During the first scan around the cell under the primary scan control 74 (Fig. 2, not shown) the number of pulses produced by each of the circular steps is counted and the contour length and hence cell size is determined at 76. The direction of each step is determined by differentiators at 80 and the sequence of directions determines whether the cell is circular or otherwise at 82. During the second scan around the cell under the control 84, at every fourth step the beam traverses the cell and returns only when on the left-hand side of the cell and blue, red and pink filters give signals indicative of the colour of the cell at 88. The blue filter is coupled to amplitude detectors to distinguish between dark and light blue and also to a pulse width decoder and single shot multivibrator with a counter in order to distinguish between a blue nucleus or granules. The characteristics corresponding to the different cell types are gated together 78 and the numbers of each type counted. After the second encirclement of the cell the search beam crosses over the cell whilst blanked out and continues across the slide until it encounters another cell.
