Title: Improvements in and relating to cinematographic film traction apparatus
IPC: G03B1/22
Filed: 1953-02-20
Abstract: 738,317. Kinematograph apparatus. KINGSTON, A. W. Feb. 8, 1954 [Feb. 20, 1953], No. 4866/53. Class 97 (1). An intermittent film feed mechanism is driven from a constant-speed drive through two devices, each having a continuously varying velocity ratio, in series, both devices being arranged to drive at maximum speed while the intermittent mechanism is driving the film. In the form shown a motor-driven shaft 39 carries a disc 40 having a pin 41 engaging a slotted arm 38 on a shaft 33 which is offset from the shaft 39 and which carries an arm 34 with a pin 35 engaging a slotted arm 32 on the shaft 30 on which is mounted the cam 29 which reciprocates the claw member 25 on the rods 26, 27. The pin and slot devices and the cam 29 are disposed so that both devices transmit their maximum velocity simultaneously while the cam is moving the member 25 downwards. The end 55 of the member 25 engages a peripheral cam 53 to rotate the member about the rods 26, 27 to cause engagement of the claws 28 with the film. As shown, this cam is driven by 2: 1 reduction gearing 30<SP>1</SP>, 531 from the shaft 30 so that the claw engages the film only on alternate downstrokes. For use in connection with television using British frequency standards the frequency of the member 25 may be 50 per second to produce a frame frequency of 25. For use on U.S.A. standards the frequency of the member 25 is 60 per second, the gearing 30<SP>1</SP>, 53<SP>1</SP> has a ratio of 1: 5 and the cam 53 has two operative portions which cause the claw to engage the film on the first and fourth of each group of five strokes of the member 25, thus producing film feeds at intervals of <SP>1</SP>/ 20  second and <SP>1</SP>/ 30  second alternately. In the arrangement shown each of the members 32, 34, 38 has a balance weight. In another arrangement their relative angular disposition and the offsetting of the shafts are arranged so that these members and the cam 29 balance one another. In a further arrangement the cam 53 is driven from a separate pin and slot device driven from the shaft 39. In the arrangement shown a shaft 52 is driven from the shaft 39 through gearing 44, 45, 47, 48, 50, 51. The shaft 52 transmits a drive to the other parts of the film feed mechanism.

Abstract: 275,878. Marks, E. C. R., (Barber- Colman Co.). Feb. 21, 1927. Winding-machines. - Relates to mechanism for finding the end of the yarn or thread upon a yarn mass and for carrying the end away as desired, and has special reference to automatic winding-machines of the kind described in Specification 156,607 wherein" winder-tending mechanism " is arranged to travel along the machine and to tie the ends from reserve bobbins to the ends on cheeses or cross-wound yarn masses other than those that have attained the desired size and to perform other operations necessary in the production of cheeses. An end is drawn from a cheese c, which is rotated to unwind the end, by means of a suction tube 291 which is then moved about a pivot 600 to allow a hooked member 324 to rise and thus to engage the end and carry it to the knotter. A carriage 89, as in the mechanism described in Specification 156,607, travels along the machine and when it reaches a winding-unit the cheese is rotated by a roller 278 on the leading side of the tube 291 and by a roller 301 on the following side, so that an end f, Fig. 2, together with, may be, a loose coil pulled off laterally and forming a loop e is drawn into the tube 291, which is then turned about its pivot 600 by a cam 609 engaging a bowl on a bracket 607 rigid with the tube so as to bring one side of the loop e between shear blades 605, 606. Thereupon, the hooked arm 324 completes its upward movement engages the end f and then moves downwards to carry the end f to be tied to the end from the reserved bobbin, the blade 606 being operated to sever the loop e which is then drawn into the tube 291. When the tying is completed the advance of the mechanism brings a roller 391 beneath the cheese to rotate it in the reverse direction to take up the slack of the tied ends.

Title: Apparatus and process for ageing alkali cellulose
Inventor: MORE JOHN WALTER
IPC: C08B1/10
Filed: 1959-02-12
Abstract: Steeped and shredded alkali cellulose is supplied, via a shoot 7, to a tower 1, whence it drops into a spreader 8 comprising a reversible conveyer belt 9, mounted upon a carriage 10.  The carriage 10 reciprocates between two positions in which it lies directly above the opposite ends of the interior of the tower. The tower is of uniform <PICT:0894933/IV (a)/1> cross-section and is provided adjacent to its middle and bottom respectively with transverse extractor mechanisms 2 and 3.  Each of them comprises a number of extraction rolls consisting of shafts 2a or 3a disposed in parallel across the width of the tower and carrying picker fingers 2b or 3b in the form of slats parallel to and projecting radially from the shafts.  The extraction rolls may be rotated continuously or intermittently during operation suitably through only a portion of a revolution each time they move.  Below the first extractor mechanism 2, a duct 4 encircles the tower and communicates with the interior of the tower by means of inlet ports 5 shielded by baffles 6.  During operation a mass of alkali cellulose filling the cross-section of the tower is built up above each of the extractor mechanisms and the rate of feed or fresh alkali cellulose and the rate of intermittent rotation of the extraction rolls are controlled so as to maintain constant the depth of each mass.  After passing through the first extractor mechanism 2, the alkali cellulose is subjected to aeration by contact with a slow current of air introduced via an air supply pipe 11, the duct 4 and the ports 5.  The alkali cellulose subsequently passes down the second mass and is removed from the bottom of that mass by the second extractor mechanism 3, whence it is collected by a conveyer 12.  Instead of air, oxygen is an oxygen-containing gas other than air may be introduced into the tower.  The oxygen, air or other oxygen-containing gas may be prewarmed or prehumidified.  More than one intermediate extractor mechanism with associated aeration means may be provided.  The tower may be provided with a jacket through which a heat transfer medium is circulated, but the temperature of the alkali cellulose is kept constant during the ageing preferably by controlling the temperature at which the cellulose is steeped in aqueous caustic alkali, the tower in this case being lagged to reduce heat losses and the temperature being maintained in the tower by the heat of the ageing reaction.  The invention increases the output of aged alkali cellulose per unit of cross-sectional area of the tower.
