Abstract: 317,972. Parkes, S. R. July 28, 1928. Vehicle-window opening and closing apparatus. -Vehicle-window regulators of the kind in which a sliding panel is raised or lowered by means of a chain and sprockets or lever mechanism, and in which a self-locking device holds the window in any position, are provided with a quick release to allow the window to drop by its own weight or to be raised by hand. The chain sprocket 12 is connected to the driven member 13 of the selflocking mechanism by a dog-clutch 20, 21 which is adapted to be disengaged by means of a cam lever 51 pivoted in the handle boss and engaging one of two contacting slidable shafts 25, 23, the outer of which 23 is riveted to the sprocket 12. The contacting ends of the spindles 23, 25 are rounded. The slidable shafts may be operated by a projecting end operated by hand and retained in the released position by hand or by a spring- pressed bolt engaging a circumferential recess in the shaft. The clutch members 13, 7 are engaged by pairs of rollers 17, 18 on a pin 16 extending through the driven sleeve 9. The roller 17 engages a cam-shaped recess in the member 13 by which an axial disengaging movement is given to the member during an initial lost movement of the handle. Suitable sash-balancing springs or weights may be combined with the apparatus. The regulator is mounted on a column 6 strengthened by corrugations and apertured for securing to doors &c. of different depths. The lower sprocket, when provided, is slidably mounted on the column 6 by means of a sliding carrier 32, Fig. 3, on which a tensioning spring 35 acts.

The container may also be provided with corrugations by rolls 6 as described in the parent Specification. After forming the ribs and corrugations the rolls 10, which are provided with flanging collars 9, may be moved axially simultaneously by lever mechanism 12 .. 15 to perform the flanging operation. The rolls 8 may be independently or simultaneously adjusted to suit containers of different lengths or to obtain flanges of different heights. The rolls at one end of the shafts may be further adjusted to obtain the same height of flange at opposite ends in case during the operation more metal is drawn in from one side than from the other. This adjustment may also be effected to obtain flanges of different heights at opposite ends. The flange may be formed internally by transferring the flanging rolls 10, 8 to the opposite shafts. The grooved rolls 5 may be axially movable instead of the rolls 2. The rolls 8 may be adjusted during rotation thereof. For this purpose the shaft 4 may contain one or two rotatable threaded spindles engaging nuts provided with projections which engage the rolls through slots in the shaft.

Abstract: 532,949. Cellulose derivatives ; mixing machines. BRITISH CELANESE, Ltd. Aug. 2, 1939, No. 22402. Convention date, Aug. 2, 1938. [Class 2 (ii)] [Also in Group II] Apparatus for the continuous precipitation of cellulose acetate or other organic derivative of cellulose from solution comprises an elongated and substantially horizontal precipitating chamber divided into zones by baffle plates permitting communication from zone to zone, a shaft extending through all the zones and carrying blades for continuously propelling material through the zones and for mixing the material, an inlet at one end of the chamber for the solution to be treated, an inlet for precipitating liquid at or near the inlet for the solution, a further and independent inlet for precipitating liquid removed from the former in the direction of the outlet end of the chamber, and a sluiceway outlet for precipitated material. The bottom of the chamber may be semi-cylindrical. Some of the zones may be formed by downwardly depending baffles and others by upwardly extending baffles. Fixed transverse rods may be placed above the shaft in zones following upwardly extending baffles and below the shaft following dependent baffles. The solvent power of the solvent is first reduced by incorporating a precipitating liquid with the solution in an early zone and the cellulose derivative is then precipitated by incorporating further liquid with the solution in a later zone. Separate supplies may be connected to the different inlets for the precipitating liquid so that a dilute solution of precipitate may be added at an early zone and a more concentrated solution at a later zone. The precipitating liquid in both the diluting and precipitating zones may be 20 per cent. acetic acid or for low viscosity cellulose acetate there may be used water alone for precipitation. As shown in Fig. 1, the cellulose ester or ether solution flows from tank 1, into vessel 5 which comprises a cover 6 and a U- shaped bottom 8. Plates 11 extending from the top and a plate 12 extending from the bottom divide the vessel 5 into zones. Across the vessel are transverse rods 13 below shaft 20 and rods 10 above the shaft. These rods together with blades 14 cause the cellulose derivative solution to be well mixed with the precipitating liquid which is supplied from tanks 19, 21. The precipitated cellulose derivative and the liquid pass down sluice 22 to a separator 23. The liquid is withdrawn through pipe 24 and the cellulose derivative passes through conduit 25. Sodium carbonate or an alkaline earth metal salt may be added at one or more zones to neutralize acid catalyst. The gas produced when a carbonate is used leads to the production of a voluminous precipitate.
