Title: Method of and apparatus for the precipitation of cellulose esters from solutions thereof
IPC: C08B3/16
Filed: 1965-04-20
Abstract: <PICT:1071325/C3/1> <PICT:1071325/C3/2> A cellulose ester is precipitated from its solution in solid pieces of a predetermined and easily washable shape and size, by forming a form of precipitant on the upper surface of a flat, stationary nozzle, continuously passing the solution to be precipitated through apertures in said nozzle into contact with said film, cutting at regular time intervals above said surface the fluid jets of the solution, and removing continuously from the nozzle the precipitated product suspended in the precipitation liquor. The precipitatant may be used in an amount by weight which can be reduced to less than a fifth of the amount by weight of the solution to be precipitated.  The cellulose ester may be cellulose mono-, di- or tri-acetate, propionate, butyrate, acetoformate, acetopropionate or acetobutyrate.  Where cellulose acetate is precipitated, it may be in a solution obtained by acetylation of cellulose and the solvent may be acetic acid or acetone.  The precipitant may be water, aqueous acetic acid, ethyl ether or a mixed hydrocarbon solvent.  Preferably, cellulose acetate of acetyl content (expressed as acetic acid) greater than 50% is precipitated by aqueous acetic acid.  After precipitation, an aqueous acetic acid may be obtained with an acetic acid concentration higher than 60% by weight.  In apparatus as shown, cellulose acetate solution is applied to the annular trough 8 and is forced through the holes 4, to form jets of liquid which are precipitated by the precipitant which is supplied through 7 and flows as a thin film over the surface containing the holes 4. The liquid jets are cut by the rotating cutters 13 and the solid pieces of precipitate so formed, together with excess solvent and precipitant, pass into the trough 11 and are removed at 12. In a modified arrangement (not shown) the shaft 10 is tubular and is connected to the pumping system for the precipitant, the shaft 10 carrying, in addition to blades 13, one or more tubular arms the lower ends of which are provided with distributors.

Abstract: 1,114,876. Reciprocating conveyers. AMERICAN MACHINE & IRONFOUNDRY CO. 19 April,. 1966 [22 April, 1965], No. 17060/66. Heading B8A. Cigars which have been wrapped in cellophane are directed to a packaging machine by infeed conveyers 50, 52, intermediate conveyers 54, 56 and a discharge conveyer 58. All the conveyers are of the reciprocating rake type and are driven by a single motor. The conveyers 50, 52 are identical, as are the conveyers 54, 56. The rake conveyer 50 comprises a driven rockable arm 80 connected to a main block 98 which slides on rods 102, 104 and which carries a pivot block 99. This block supports a rake 110. As the arm 80 moves towards the right as seen in Fig. 5, the initial movement rotates pivot block 99 and raises the rake 110 which passes above the cigars as it moves to the right. As the arm starts its movement to the left, pivot block 99 rotates clockwise and, having passed the rake over a selected number of cigars, moves downwardly and draws the group into registry with conveyer 54. To facilitate maintenance &c. the rake assembly may be lifted about a shaft 218 by a knob 120. Chains 128 are fixed to engage and align the cigars. A channel for the cigars is formed by guides 130, 132 of which 132 is adjustable for cigars of different lengths. A hold-down plate 160 bears on the cigars after they pass from beneath the chains 128. The rake conveyer 54 comprises a driven rockable arm 184 which by a rod 190 and a carriage actuating element 192 is connected to a carriage 204. Rakes 248, 251, 252, 253 are secured to the carriages and are operated in unison, between raking and non-raking positions, by a cam mechanism which actuates rake 252 only. This rake is supported on a rod 264 rotatable by the action of a cam 280 which engages a roller plate 272 secured to the rod 264. With the carriage 204 moved to its righthand position in Fig 9, rake 252 is raised by clockwise rotation of the rod 264 so that the rake clears the cigars as it is moved towards the left. In the extreme left-hand position a cam 282 actuates plate 272 and the rake 252 is lowered in position to engage a group of cigars. A leaf spring 270 maintains the plate 272 and the rake in whatever position it may be actuated by the cams. The channel of the conveyer is adjustable for cigars of differing diameters. The discharge conveyer 58 has a rake 376 and a hold-down plate 378 which are raised, lowered and reciprocated by action of a cam 320, linkage 326, 336 and a block 338 which supports the rake. The block 338 is pivoted on a block 342 slidable on bars 350, 352. Means are provided to disable one rake of the multi-rake conveyer 54 or 56 if there are less than the required number of cigars. The conveyers 50, 52 are operated 180 degrees out of phase and the conveyers 54, 56 operate 180 degrees out of phase but in unison.

[Class 97 (iii)] In a gyroscopic apparatus erected by pendulous shutters 10, 11 controlling air ports 12, 13, damage such as detachment of a shutter from its supporting spindle 15 is avoided by choosing the cross-sectional area of the shutter spindle along a part or the whole of its length so as to provide sufficient torsional resilience to absorb inertia forces set up if (through variations of manufacture) one shutter alone engages its stop. As shown, the resilience is obtained by reducing the centre portion of the spindle. The end portions of the spindle engaging the bearing surfaces in the casing 14 are burnished. In assembling the shutters, one shutter is first soldered to one end of the spindle whilst these parts are maintained in a jig with the spindle at right-angles to the face of the shutter, the parts are removed, the spindle is inserted through the bearings in the casing 14, the second shutter is added, spacer bars 20 are inserted temporarily between the two shutters and the casing so as to maintain the faces of the shutters parallel to the planes of the air outlets, locating bars 22 are inserted temporarily through the air ports to provide abutments for the edges of the shutters whilst the second shutter is soldered to the spindle, and thereafter the spacer and locating bars are removed. The shutters are spaced from the casing 14 by washers 19. Each shutter is provided with an adjustable mass 24 for the purpose of adjusting the shutters to central position, this being effected whilst the gyro casing is held erect in a jig.
