In an alternative embodiment, the strip B is secured to a flap 15 and projects slightly below the bottom wall 17 of the carton. The strip may be secured with a hot melt adhesive of the ethylene vinyl acetate type, and may have a serrated cutting edge. If the carton contains material in a sealed bag the strip B is used to open the bag.  The strip B is fed from a roll 41 through a cutting device 42 where a fly cutter (52), Fig. 3, not shown) cuts teeth in the strip and then over a roller 65 which operates microswitches 66, 67 controlling the rate of feed. Subsequently the strip passes to an applicator 43 where it is severed into appropriate lengths and applied to a carton blank that has previosuly been supplied with adhesive. Alternatively adhesive may be applied to the strip B, The applicator includes a fixed block 70 carrying drive wheels 73, 74, a nip roller 74a, and a sliding block 81 carrying idle pressure rollers 82, 83. A piston and cylinder 93, 94 move the sliding block towards the fixed block to feed the strip B to the carton blank. When the sliding block is retracted a cutting edge 86 shears the strip against a block 75. Photo-electric cells sense the presence of a carton blank and by means of a fibre-optic device initiate the application of adhesive. A further fibre-optic device controls a valve which permits actuation of the piston and cylinder 93, 94.

Filed: 1926-11-27
Abstract: 280,714. Peters & Co., Ltd., G. D., and Rawlings, V., P. Nov. 27, 1926. Fluid-pressure.-A control valve for compressed-air brakes on a locomotive or tractor under the control of a vacuum train-pipe is provided with two pistons 4, 5 of equal diameter and smaller than the control-valve piston 2, the space between them being constantly open to atmosphere by a port 18. Leakage is thus prevented between the space 15 connected to the compressed-air brake-cylinder and the space 11 connected to a vacuum reservoir. The space 13 on the other side of the piston 2 is connected to the vacuum train-pipe, admission of air to which causes the pistons to move so as to close exhaust ports 19 and open a valve 9 to admit air under pressure to the brake cylinder from a reservoir connected to the port 7. Brake-cylinder pressure acting on the piston 5 returns the pistons allowing the valve 9 to close so that the brakecylinder pressure is maintained proportional to the train-pipe pressure. The piston 5 also maintains this proportionality during exhaust of the brake cylinder through the ports 19. A spring 20 bears on the piston 2 urging the pistons in a direction to effect unseating of the valve 9, and is adjustable by means of the nut 21 on the screw peg 22. In a modification of the invention a diaphragm replaces the piston 2 and the piston 4 may also be replaced by a diaphragm. A driver's valve is provided on the locomotive to control the compressed-air brakes and a compressed-air train-pipe when the train is provided with compressed-air brakes.

Filed: 1947-11-12
Abstract: 645,369. Gauging-apparatus. PETTY, J. D. PAXTON-. Nov. 12, 1947, No. 30167. Class 106 (ii)] In a machine for gauging a linear dimension or other physical quantity of an article, a movable member 6, positioned according to the magnitude of the quantity,' operates a selector switch, Fig. 3, to illuminate one of a number of signal lights (not shown) each corresponding to a range of magnitudes of the quantity and indicating a shoot or other route for the article for that range, the light remaining illuminated until extinguished by movement of the article along the indicated route. In the lineardimension gauge shown, the article is a cylinder 1 resting on a bed 2, 3 which is slid into the gauging position, determined by an adjustable stop 7, by a knob 9. Further pressure on the knob closes a spring-released switch to energize a solenoid 25 and actuate a thrust cup 45 which has a spring-pressed ball engaging an annular groove in a plunger 15. The plunger therefore moves forward until stopped by the articleengaging member 6 when it is freed from the cup. The member 6 has a stepped collar, thus providing three stop-surfaces 6, 13, 14 corresponding to different ranges of diameter of the cylinder 1 and there are three corresponding spring-pressed balls 22, Fig. 3, selectively engaged by a contact ring 39 on the plunger 15 to light the associated signal light. When the gauged cylinder is passed down the corresponding shoot (not shown), a switch in the light circuit is opened, thus de-energizing the solenoid and returning the cup 45 and, through a flange 18, the plunger 15 to the initial position. According to the Provisional Specification, a number of dimensions may be gauged simultaneously.
