Title: Improvements in or relating to Controlling Mechanism for Train-brakes.
IPC: B60T13/64
Filed: 1916-08-28
Abstract: 101,347. Knorr-Bremse Akt.-Ges., and Hildebrand, W. Aug. 28, 1916. Addition to 106,131. Fluid-pressure.-Relates to combined single and double chamber brake systems in which, in an application, one chamber of the double-chamber brake cylinder supplies the single-chamber cylinder, and after equalization is vented to atmosphere. The invention comprises a triple valve adaptable both for high-speed and ordinary trains by means of a hand-cock controlling connexions whereby, for slow-speed trains, the accelerator valve is cut out, a throttled supply passage to the single-chamber brake cylinder is substituted, and the double-chamber braking action is rendered ineffective. In the release position, Fig. 1, the train-pipe at L feeds into the double-chamber cylinder by passages 1 - - 5 and pipe D, and the single-chamber cylinder is open to exhaust by pipe F and passages 6 - - 10. The pipe E connects the slide-valve chamber II with the idle-space or control chamber of the double-chamber cylinder. Figs. 1 and 2 show the hand-cock H in position for highspeed working, in which the train-pipe L is connected by passage 18 with the piston chamber of an accelerator valve q, the piston of which controls the connexion between passages 14, 16 forming the unthrottled means of connexion between the idle-chamber of the double-chamber cylinder and the single-chamber cylinder. When the train-pipe pressure is suddenly reduced, the valve q, moves down and opens the exhaust port 15 to the train-pipe. The pressure air also flows from the idle chamber by pipe D, cock H, passages 14, 15, valve i, and pipe F to the singlechamber cylinder. When equalization is effected between the idle and single chambers, the valve i moves up to cut off the single chamber and to open the idle chamber to exhaust port 15 by passages 19, 20. For slow-speed working, the cock H is turned to the position shown in Figs. 3 and 4, cutting off the train-pipe L and idle-chamber pipe D from the passages 18, 14, so that neither the train-pipe or the idle-chamber is vented to atmosphere, and the flow to the single-chamber cylinder from the idle chamber is by the passages 5, 6 and throttled slide-valve passages. A chamber is provided for collecting moisture.
Patent GB-591749-A (GB)
Title: An improved method of and apparatus for manufacturing containers from flexible sheet material
IPC: B31B70/00
Filed: 1945-05-15
Abstract: 591,749. Making boxes. BEE BEE BISCUITS, Ltd., and BUXBAUM, E. K. May 15, 1945, No. 12164. [Classes 18 and 94 (ii)] An open container is made by applying a sheet of flexible material to the end face of a block, folding the marginal portions of the sheet on to the side faces of the block leaving wings or ears projecting at the corners of the block, and with the sheet held by suction to the block, moving it to successive operating positions in which the wings are folded down against the walls of the container and sealed in position, and the complete container is withdrawn from the block. In the machine shown, a web of material is fed over a fixed table 14, over a reciprocating table 15, and beneath a metal strip 16, and is clamped to the table 15, when the latter is in its rearmost position, by pads operated by a suction cylinder 18. The table 15 and the web are then advanced until the forward edge of the web is held by suction heads 19 carried by a slidably mounted bracket 20, when the latter is in its rearward position. After the suction is cut off from the cylinder 18, the clamping pads release the web, the table 15 returns to its original position. and the web is again clamped to the table, so that a guillotine 21 may cut off a sheet of the required size. A rotatable shaft 6 carries a disc 7 to which are secured four radial arms 8, the outer ends of which carry blocks 9, 9a, 9b, 9c, respectively, around which the containers are formed and by which they are carried to the successive operating positions. The sheet is positional underneath the block 9 and above a vertically movable table having four flaps 23 hinged thereto. The table is raised and the flaps swing upwardly to fold the edges of the sheet so as to form a rectangular casing with ears at the corners thereof. The table and flaps are retracted but the sheet is held to the block by means of suction applied through holes in the block. The shaft 6 is rotated to the second operating position 9a where the ears at the two rear corners of the casing are folded forwardly by a pair of arms 26 carried by a shaft 27. The shaft 6 is further rotated to the third operating position 9b when the two forward ears are folded on to the casing by a pair of heated plates 31 which also seal the folds of the container to a predetermined height. A further rotation of the shaft 6 brings the container to the fourth operating position 9c where it is removed from the block by means of a pair of plates 33 carried by a vertically movable arm 34 and having holes to which suction is applied, the suction holding the container to the block being released. The suction connection to the holes in the plates 33 is then broken and the container drops into one of the cups on a conveyer 11 whence it is taken to be labelled, filled, and sealed. Specifications 542,148, 542,228, 542,244, and 543,463, [Group XVI], are referred to.
