Material is pressed into two cans 24 simultaneously by plungers 102, 104 which press material out of measuring boxes 16 as these move with the cans. In the form illustrated, empty cans carried by rotating plates 20, 22 are first raised by rollers 68 engaging a cam track 72 into sealing engagement with a plate 82 cooperating with plates 86, 84 to carry the measuring boxes in synchronism with the cans. The measuring boxes and cans are filled with loose material which is manually levelled with the plate 84, and then pass beneath the plungers 102, 104 which are moved in circular paths 110, 112 to compress the material into the cans. Each plunger 102, 104 may terminate in a pneumatically operated extension (Fig. 8, not shown), so that the compressing stroke can be varied. The plungers are driven by cranks 160, 162, the stroke of which may be varied, and are constrained by guides 124 to follow the path of the cans. The volume of the measuring boxes 16 may be varied. A further pair of plungers may provide an initial compression.

G.; 363, Penning- ton Avenue, Passaic, both in New Jersey, U.S.A.) Feb. 29, 1932, No. 6048. Convention date, March 20, 1931. [Class 70.] Rubber material, particularly filaments, sheet or tube, made by extruding latex into a coagulant, is dried at a temperature which gradually increases as the material advances, and is vulcanized by passing through an inert gas at a temperature of at least 325‹ F. The temperature of the gas, which may be steam, carbon dioxide or ammonia, is from 325 to 400‹ F or higher, as compared with the normal vulcanizing temperature of 280 to 300‹ F. As shown in the Figure, a rubber filament, which may contain vulcanizing ingredients in the colloidal form or in solution, after passing through a coagulating bath 5 and a washing bath 8, is conveyed on belts 10, 11, 12 through a drier 13, the temperature, which may be from 180 to 300‹ F., in which is arranged to be higher at the exit end than at the entrance. It then passes through vulcanizer 21, which is supplied with heated gas from the superheater 52. Thermometer 24 may automatically control the vulcanizing temperature.

Title: Improvements in knitting-machines
IPC: D04B9/46
Filed: 1919-03-11
Abstract: 151,297. Reggio, G. March 11, 1919. Circular machines; knitting stockings. To obtain a shaped effect at the knee, calf, heel, sole, and elsewhere by varying the size of the loops in the same course, using a splicing-thread with the longer loops if desired, the needlecylinder is moved up and down during the formation of each course by its supporting-tube G, which carries an incline F resting on a screw E at the lower end of a lever O suspended from a lever B resting on one of four cams on a cam shaft A. The lever B normally rests on a cam concentric with the shaft., but can be moved under the control of the pattern drum J to rest on any of three cams which are of suitable shape for making loops of gradually increasing lengths for the knee, calf, and heel respectively. To obtain a tapering effect below the calf, the movement imparted from one of the cams is modified by a pattern-controlled lever V connected to the lever 0 which gradually pushes the screw E along the surface of the incline F; there is thus a certain amount of lost motion and the position at which the tube G begins to be lifted by the lever 0 is varied.

Title: Improvements in or relating to gun mountings
IPC: F41G3/12
Filed: 1944-04-01
Abstract: 581,937. Gun sights for aircraft. RICE, E. A. B., ROSE, A. G., NICHOLLS, K. H., CURTIS, S., WAITE, L. W., and ROSE BROS. (GAINSBOROUGH), Ltd. April 1, 1944, No. 6106. [Class 92 (ii)] Relates to sighting devices for gun mountings of the kind described in Specifications 577,908 and 577,919, wherein a sighting arm 11 operates follow-up mechanisms for moving the guns and wherein the sight 12 which is pivotally mounted on the arm is given a compensating movement for any movement the arm may make before the follow-up mechanism operates. According to the invention, means operable in synchronism with the firing mechanism are provided for restraining the sight from pivotal movement on the arm 11 during the firing of the guns. In the construction shown, the arm 11, as in Specification 577,919, is pivotally mounted about a horizontal axis on a member 16 which is pivotally mounted about the training axis of an aircraft turret 17, and the compensating movement in training is imparted to the sight by links 19, 42, 32, 33. When a button 31 is depressed to actuate the firing solenoids of the guns, a further solenoid 39 in the circuit actuates arm 38 of a two-armed lever 37, 38 and causes a member 36 on arm 37 to descend and to clamp link 42 between it and a fixed gripping member 34. The clamping mechanism and solenoid 39 are mounted on arm 11. The clamping of link 42 prevents the sight moving about the training axis on arm 11 during firing. A similar clamping mechanism controlled by another solenoid prevents the sight from moving about axis 13 when the firing button 31 is depressed.
