Abstract: 637,548. Feeding webs. TURNER, R. Aug. 22, 1947, No. 23334. [Class 100 (i)] [Also in Groups XVII and XXIV] A control device, of the kind in which a feeler is arranged in the path of articles to be wrapped and adapted if the supply of articles is interrupted to actuate mechanism for disengaging the drive to feed rollers for the wrapping material comprises a clutch 6, 7 in the drive to the feed rollers 2, 3, an operating lever 13 pivotally connected to a collar 11 by trunnions 12, a continuously rotatable cam 14 associated with the lever, whereby the latter is periodically displaced from a normal dependent position, a strip-operating member 18 connected to the feeler member 17 and adapted to co-operate with a trip element 25 in such a manner that movement of the feeler 17 causes the element 25 to carry a knife edge 28 into engagement with the lower part of lever 13 when said lever is displaced from said normal position, whereby on return of said lever 13 by the action of the cam 14 the lever 13 is moved about the edge 28 to effect disengagement of the clutch. The collar 11 carrying the lever is axially slidable on a shaft 8 and spring-urged by a spring 10 so that the clutch 6, 7 remains in engagement. The lever 13 carries a roller 13a which engages a face cam 14 mounted on a shaft 15 and having a depression 14a which permits the lever 13 under the influence of a spring 12a to move about trunnions 12. If an article 1 is missing from the conveyer band 22 the feeler 17 can move downwardly when a roller passes on to a flat on a cam 20 timed with the cam 14, during the downward movement of the feeler an arm 23 projecting from the member 18 engages a projection 24 on a trip element 25 rotatable on a shaft 16. The consequent rotation of the element 25 causes a knife edge 28 to move into engagement with a notch 27 on the end of lever 13. When the roller 13a rides out of the depression 14a the lever 13 is displaced about the knife edge 28 so that the clutch 6, 7 is disengaged and a brake 29 urged by springs 31 engages the part 7 to stop the feed roller 3. A trip return lever 33 oscillatable on the shaft 16 by a cam 32 and roller 36 causes the positive disengagement of the element by means of a screw 35. The operation is repeated if there is still no article under the feeler 17.

Patent GB-793858-A (GB)
Title: Solutions of cellulose triacetates
IPC: C08J3/09
Filed: 1955-08-16
Abstract: Solutions of cellulose triacetates in mixtures of methylene chloride and an aliphatic alcohol of 1-4 carbon atoms contain a proportion of water above 0.3 per cent of the weight of the solution (reckoned as anhydrous) but below the minimum proportion which will make the solution turbid.  The methylene chloride-alcohol mixture preferably contains 80-99 per cent by weight of methylene chloride, and mixtures of methylene chloride and methanol containing 90 per cent or more of methylene chloride are advantageous.  When the solutions are to be used for spinning, the cellulose triacetate concentration may be above about 15 per cent and preferably between about 17 and 27 per cent.  The water which the solution is to contain may be present in or added to the solvent mixture or to the cellulose triacetate before the solution is formed, or the whole or part of the water may be added to the solution after it has been formed.  The cellulose triacetate and the solvent mixture may be mixed together in known manner, and the solution is preferably subjected to the vigorous shearing action described in Specification 785,806.  The solution may be formed at about 20-30 DEG  C. and then cooled to - 30 DEG  C. or heated to above 55 DEG  C., while mixing, as described in Specification 779,220.  In an example, a cellulose triacetate is dissolved in a mixture of 94 parts by weight of methylene chloride and 6 of methanol to form a solution having a cellulose triacetate concentration of 18 per cent.  Water is gradually added to the solution, and it is found that the latter has its lowest viscosity and best spinning properties when its water content is between 0.3 and 0.72 per cent by weight (based on the anhydrous solution).  When its water content reaches 1.2 per cent the solution becomes cloudy and its filterability falls markedly.  It is also found that, as the percentage by weight of methanol in the anhydrous solvent is increased to 12, the minimum proportion of water required to render the solution turbid is increased to 2.1 per cent (based on the anhydrous solution).
