Title: Improvements in and relating to electric switches with arc-extinguishing means
IPC: H01H33/76
Filed: 1938-07-28
Abstract: 517,447. Gas-blast switches. BRITISH THOMSON-HOUSTON CO., Ltd. July 28, 1938. Nos. 22481, 22482, 22483 and 22484. Convention dates, July 29, 1937, Aug. 5, 1937, Aug. 5, 1937, and Aug. 7, 1937. Addition to 467,809. [Class 38 (v)] The invention of the parent Specification is modified in that the tubular member communicates with the blow-out chamber only at a part or parts located intermediately of the ends of the member. Fig. 1 shows the gas-evolving tube 1, the chamber 2 housing the fixed contact, the movable contact 4, and filling member 3 which may also be of gas-evolving material. The tube 1 consists of an inner carbamide-resin tube, reinforced by an outer hard-fabric tube screwed at 9, 10 into the blow-out chamber 6. This tube is further reinforced by a tube 11 made of non- carbonizing material, such as the polymerized acrylic acid derivatives described in Specification 483,128. The evolved gas passes through openings 5 into the chamber 6 and thence through a metal gauze cooler 7 and vents 8. In another embodiment, the oval blow-out chamber 22, Fig. 2, is formed of parts 25, 26, 27 braced together by an insulating tube 29 provided with opposite threads 15, 16 The evolved gas thus passes through the openings 5 into an intermediate chamber 20 within tube 29 and then through apertures 21 and preferably through a metallic gauze cooler 14 wound or otherwise mounted on the tube 29, into the blow-out chamber 22. A second cooler 13 may be located over the vents 8. To minimise the gas pressure impact on the walls of the blow-out chamber when the latter is oval, Figs. 4, 5 (not shown), the tube 1 is surrounded by a spaced concentric cylinder for taking up the first shock, this cylinder being, e.g., of metal and apertured so that the gas passes readily therethrough. A gauze cooler is provided on the inside of the cylinder and may itself be constructed to function as the " shock " cylinder. The " shock " cylinder may be made of springy material. e.g., of steel, Fig. 6 (not shown), with overlapping longitudinal edges controlled by a compression spring to vary the opening between these edges according to the gas pressure. In a further embodiment, the oval blow-out chamber 44, Fig. 7, has the tube 1 arranged at one focus, and at the other focus the chamber is provided with a dome 46 and if desired a similar lower dome 40 in which the vents 47 are provided. A cooler 49 is provided coaxial with the dome 46 which is braced by a bolt 48.

Title: Improvements in or relating to devices for supplying a machine with cylindrical articles
IPC: B23Q7/10
Filed: 1936-08-21
Abstract: 480,283. Feeding cylindrical articles from hoppers. DELAUNAY, J. E. Aug. 21, 1936, No. 23072. [Class 78 (i)] Cylindrical articles such as tubes are fed one at a time from a storage hopper by transfer-mechanism which delivers each article, as it is segregated from the mass, straight to the machine without any intervening movement. Thus, the movement of a guided, forked, actuating rod 19, 20 at right-angles to the plane of the paper towards the eye, causes spaced cams 17 to swing a pair of members, 9 about the pivots 11 against the action of springs 12 and thus causes their wedge-shaped edges 14 to push all the articles 8, except the lowest one, upwards in the inclined slots 6, thus enabling the slot 15 to close over and segregate the lowest article. During the latter part of the movement the surface 14 also swings levers 51 against the action of springs 53 and thus prevents the raised articles jamming in the mouths of the slots 6. This movement of the rod 19, 20 also moves the delivery rod 27 on an idle stroke by means of the connecting bar 28, so that it moves past the article 7 which is to be delivered on the succeeding stroke. The pusher-bar 29 carried by the rod 27 is swung aside out of register with the article during the main part of the idle stroke by a fixed cam acting on the lever 31, and is restored again by a second cam towards the end of the stroke after it has passed the end of the article. Also, during this stroke locking-bars on the cams 17 enter the holes 40 and lock the displaced members 9 to the fixed members 35. On the return stroke, the member 29 pushes the article 7 axially to a point where it is engaged by the gripping-members which feed it into the machine, the locking-bars are removed from the holes 40 and the cams 17 are withdrawn from the members 9. Towards the end of the stroke the member 29 is moved again out of register with the article ready for the next stroke. On the released members 51 and 9 being restored by their springs the articles fall by gravity until another one is in position for being delivered in the following cycle of operations. The movement of the apparatus may be interrupted on the return stroke to allow the gripping-members time to draw the article out of the apparatus. For treating articles of different diameters at different times, a series of inclined slots 6 may be formed on plates which can be rotated to bring any particular slot into the acting position shown, Similarly the members 9 may carry a series of slots 15 any one of which can be turned into the acting position.

Filed: 1956-07-27
Abstract: 794,640. Levels. GENERAL ELECTRIC CO. July 27, 1956, No. 23317/56. Class 97(2) An instrument for giving a vertical reference indication comprises a short period pendulum and a long period pendulum each capable of free oscillation about a common axis, and a magnetic coupling between the pendulums which tends to align them but which is effective only when the relative angular displacement between them is small. As shown, the long period pendulum consists of a flywheel 10 on a shaft 11 mounted in bearings 12, 13 in supports 14, 15. The flywheel is unbalanced by a screw 16. The short period pendulum 21 is mounted on a bearing 22 on the support 15 and carries an extension 27 to which is secured a vane 26 movable between the poles of a damping magnet 28 which may be a permanent magnet or may have an energizing coil 29. A bar magnet 24 secured to the pendulum 21 acts on the screw 16 with a force which decreases with relative angular displacement of the pendulums. As explained in the Specification, this results in the pendulum 21 correcting errors in the long period pendulum. Movements of the latter relatively to the support 15 are transmitted by a pick-off device 17 of the Kind described in U.S.A. Specification 1,431,627.
