Abstract: 361,598. Moulding pulp tubes. MAGNANI, A., 4, Via Roma, Casale Monferrato, Italy. Nov. 14, 1930, No. 34361. Convention date, Dec. 9, 1929. [Class 87 (ii).] Tubes are formed from fibrous pulps by supplying the pulp between a hollow forming roller and a pressure roller, the forming roller being hollow and adapted for connection to a suction device. The pulp is raised from the vat 32, Fig. 2, by the pump 3, Figs. 1 and 2, and delivered between the forming roller 1 and pressure roller 2 by the pipe 34. The forming roller 1 is perforated as shown at 5 and also provided with an annular chamber 13, Fig. 3, at one end leading to a suction pipe 15. The roller is enclosed by a removable wire cage 7. The pressure roller 2 is provided with a series of looselymounted rings 16, 17, Fig. 4, and is mounted on sliding bearings 22 adjustable by the hydraulic pistons 24 to regulate the distance between the cylinders. The pressure roller shaft rotates faster than it would do if the roller were driven solely by frictional contact with the forming roller. The pump 3 is reciprocated on the rails 27, the piston being moved during the process by the curved rail 28 and the spring 30. When the roller 1 is wound fully it is removed .from the machine and placed in the double-walled mould 42, Fig. 5. Pressure applied between the walls forces the inner resilient wall 45 against the pulp to further compress the tube, while subsequent suction releases the tube again. Afterwards the roller is withdrawn from the wire cage and then the cage withdrawn from the tube.

Title: Improvements in or relating to moving picture filming cameras
Inventor: HAMPL JAN
IPC: G03B1/50
Filed: 1959-10-13
Abstract: 931,157. Kinematographic cameras. MEOPTA PREROV, NARODNI PODNIK. Oct. 13, 1959, No. 34606/59. Class 97 (1). A kinematographic camera with interchangeable film spools having a single film feed mechanism has an adjustable objective mount coupled to an image field mask and viewfinder mask to enable one row of full film-width exposures or two rows of half film-width exposures to be made. As shown in Fig. 1, a take-up spool 8 is rotated by a spring motor at 9 coupled to a locking wheel 14 releasable by the trigger 15 and coupled to the feed spool 7 through a gear system 10, 11, 12, 31, 30 which includes a bevel gear co-operating with bevel pinion 18 to activate an eccentric 21 which drives a shutter 21 (Fig. 2) and reciprocates the claw D to feed the film F past the aperture 25 and pressure pad 26 shown in Fig. 3. A finger 27 follows the radius of the film on the feed spool 7 and, when this is almost equal to the spool hub radius, causes deflection of a lever 28 to engage a pin 29 on gear 30 thereby stopping the feed mechanism. During the motion of lever 28, an arm 42 of said lever engaging a pin 43 moves downwardly a catcher member 41 to disengage a horizon ally slidable bar 33, which if moved forwardly would (a) pivot the lever 28 out of engagement with pin 29 by means of the abutment 33a thus releasing the feed mechanism, and (b) would couple the rewind drive, in a manner to be described later. This cannot happen while the tranversely slidable objective mount 2 is in the half film width position shown in Fig. 3 since the bar 33 is connected to a member 45 forward movement of which is prevented by 2. The objective mount 2 has a pin 3 which in this position is engaged by a lever 4 (Fig. 2) one arm of which masks half the film width while the other arm supports a pivotable viewfinder mask 5. When the objective mount 2 is moved to the left in Fig. 3, the pin 3 assumes the dotted position shown in Fig. 2, thereby pivoting lever 4 to unmask the whole width of the film and viewfinder, and unlocks the member 45 which can then be moved forwardly together with the slide 33 by means of button 34 when the film has run out to unlock the feed mechanism, as described previously. The forward movement of 45 simultaneously pivots the pressure pad 26 by means of the projection 38 into the dotted position to release the film for engagement by the idle spindle 37 and causes the gear 30 to ride up the slanting portion of the slide 33 to bring into engagement the clutch 32-35 for transmission of the rewind drive to spool 7.
