Filed: 1951-01-30
Abstract: 693,518. Sterilizing apparatus. DEKKERS, P. M. C., and SIEBOLS, P. Jan. 30, 1951 [Feb. 9, 1950], No. 2343/51. Class 49. In apparatus for sterilizing or pasteurizing the contents of bottles or other containers on trucks in a tunnel comprising a heating portion of the tunnel into which the trucks enter first and in which the temperature of the containers is raised to the sterilizing or pasteurizing value by means of a stream of air heated by steam injection and a cooling portion which the trucks enter thereafter, the trucks are arranged in a continuous row and have partitions which, in distinct positions of the trucks, co-operate with baffles on the floor and ceiling of the tunnel to form a zig-zag passage for the air; the driving mechanism of the trucks is such that they are intermittently moved to occupy successively the distinct positions, whereat the direction of the stream of air with respect to the containers is reversed, and the same stream of air is passed through the whole tunnel in the direction opposite to that of the movement of the trucks. With the apparatus of Figs. 1 and 2, trucks 13 on wheels are moved intermittently through a tunnel in the direction of the arrows y, each movement of the trucks being over a distance A. Each truck has three partitions 16, 17 and 18 or has two partitions 16 and 17 or 17 and 18, the end partitions making contact or being common for adjoining trucks. Baffles 19 extend from the roof 4 of the tunnel and baffles 20<SP>1</SP>, 20" and 20<SP>111</SP> extend from the floor of the tunnel to force air blown through the tunnel to take the zig-zag path indicated by the arrows x. In a shunt conduit from the tunnel is a blower 10 and a steam injector 11.

Abstract: 809,525. Stencilling-apparatus ; feeding webs. STORK & CO's. APPARATENFABRIEK N. V., Geb. Jan. 29, 1957 [Feb. 15, 1956], No. 3138/57. Addition to 718,459. Classes 100(1) and 100(2) A machine for printing through a stencil screen on to an intermittently movable web comprising at least one reciprocating squeegee driven at a non-uniform speed over a screen support and raised during the lifting and lowering of the screen from the web to allow web feed, such that the squeegee performs an even number, e.g. two, inoperative strokes in its lifted position and a smaller number, e.g. one, operative strokes in lowered position, the upward movement of the squeegee being controlled by a rotatable member on a shaft which causes the horizontal reciprocation of the squeegee is characterized in that a transmission mechanism is provided between the shaft and mechanism for effecting such reciprocation for alternating an even number of short inoperative squeegee strokes with a smaller number of longer operative squeegee strokes. As shown, a squeegee carrier 14 is reciprocated by a connecting rod 13 actuated by a crank 11 secured to an oscillating shaft 10 driven by a pinion 56. The pinion 56 is driven by a rack 55 reciprocated by a crank 54 on a shaft 52 driven by a pinion 53 meshing with a pinion 51 on a shaft 4 carries a cam 46 engaging a follower 19 secured to a transverse beam 24 connecting a pair of levers 16, pivoted about axes 21, a beam 22 connects levers 17 pivoted about an axis 20. The levers 16, 17 are hinged at 18, such that rotation of the cam 46 effects raising and lowering of carrier 14 in synchronism with the reciprocation thereof. As shown in Fig. 4, the squeegee 34 pushes printing paste 45 across the screen 35 while performing stroke a. Towards the end of the stroke, the squeegee is lifted and performs short inoperative strokes c and b and is then lowered to behind the paste 45. The squeegee then performs stroke d followed by inoperative strokes e and f. Screen frames 37, Fig. 2, e.g. three for multi-colour printing, are supported on side rails 38, attached by adjustable clamps 39 to end members 40 having brackets 41 carrying downwardly-projecting rods 15, 23. The rods are engaged by the ends of levers 16, 17 towards the end of their upward movement to lift the screens and allow the web to move forward. The squeegees 34 carried on cross members 33 secured by clamps 32 to the carrier 14. The web is fed while the frames 37 and carrier 14 are raised by an intermittently driven belt 26, Fig. 1 to which the web is temporarily attached. The belt 26 is driven through a one way clutch 8 by a chain 7 attached to a spring 9 and actuated by a rotating crank 5. The chain 7 is attached to a slidably adjustable block 6 on the crank 5. ,
