Title: Method of and apparatus for reducing asymmetrical stresses in a generally cylindrical sheet metal side wall of a container of such a side wall
Inventor: RAGETTLI CHRISTIAN
IPC: G09F5/02
Filed: 1968-05-14
Abstract: 1,204,736. Restoring shape of articles; altering physical properties. VAN LEER (U.K.) Ltd. 6 May, 1969 [14 May, 1968], No. 22931/68. Headings B3Q and B3V.  A method of reducing asymmetrical stresses in a cylindrical sheet metal container and restoring its shape by removing any dents comprises expanding the container by radially expanding and retracting inner dies past the yield point of the metal and compressing or shrinking the container by radially movable outer dies while supporting the container interiorly by said inner dies until the yield point is exceeded and the diameter of the cylinder is  less than its original diameter and then collapsing the dies to allow the container to return to its original diameter. Apparatus for carrying out the method comprises a base 1, a head 2 and a casing 3 the base and head being connected by tension rods 4. An hydraulic cylinder 7 carried by tension rods 6 operates a conical member 9 which actuates spring-loaded segmental inner dies 10. Hydraulic cylinders 12 mounted in the head 2 reciprocate a conical member 15 which actuates segmental outer dies 17 which extend through slots in the casing 3. In order to prevent thin sheet metal from buckling the axial edges of the dies are serrated to provide zig-zag gaps between the dies.

Title: Improvements in rotary tubular furnaces
IPC: F27B7/00
Filed: 1934-08-08
Abstract: 442,030. Rotary furnaces. JOHNSON, J. Y., 47, Lincoln's Inn Fields, London.-(I. G. Farbenindustrie Akt.-Ges. ; Frankfort-on-Main, Germany) Aug. 8, 1934, No. 22940. [Class 51 (ii)] The shell of a rotary kiln is provided with devices by which the heat losses by transmission through the shell can be varied as desired. In the construction shown, the shell a is surrounded by a lagged casing b having slots d, which can be controlled by a hit-and-miss ring c operated by handles h. When the slots are open a current of air passes through the annular space formed by the casing, partly owing to convection effects and partly to the rotation of the furnace, the current due to rotation being increased by vanes e. Lateral openings g are provided for the escape of air. In a modification (Figs. 3 and 4, not shown), the casing is formed by pivoted slats operated simultaneously by an adjusting-ring. The shell may be formed with ribs f which increase the cooling effect. The regulating device may extend over the whole length of the shell or may be subdivided so that the heat losses can be controlled independently in different zones.

Abstract: 660,745. Fluid pressure brakes. WESTING HOUSE BRAKE & SIGNAL CO., Ltd. Sept. 6, 1949 [Sept. 7, 1948], No. 23024/49. Class 103 (i). In fluid pressure braking apparatus, for railway and like vehicles, of the type in which the braking pressure is varied in accordance with the load on the vehicle by means of a fulcrum, forming part of the control gear, which is adapted to be moved by linkage connected to an unsprung part of the vehicle, the displacement of the fulcrum is arranged to be automatically prevented while the brakes are applied. This is brought about by use of a special construction of carriage 21 having a slot therein through which passes a slider 29 connected at one end by links 23, 25 and bellcrank 24 to an unsprung vehicle part 26, and at the other end to an anchored spring 28. When there is no downward pressure, due to the action of the control gear, on the fulcrum lever 9, a plate 34 is caused by springs 35 to clamp the slider 29 in the carriage 21, so that movements of the links 23, 27 are transmitted to the fulcrum 20. If, however, there is substantial downward pressure on fulcrum 20, the plate 34 is pressed down on springs 35 so that the slider 29 is loose in the carriage and consequently will not transmit jolts caused by the wheels running over rail joints to the fluid pressure control gear fulcrum.

Abstract: 390,403. Photographic cameras combined with telemeters. LEITZ GES., E., Optical Works, Wetzlar, Germany. Aug. 24, 1932, No. 23671. Convention date, Oct. 17, 1931. [Class 98 (i).] In a camera provided with a telemeter mechanically interconnected with the focusing mount of the objective, the adjusting movement is transmitted to the telemeter not from the objective mount itself, but from a separate adjusting member into which different objective mounts can be fitted, this member being left in screw-threaded engagement with the camera, or with a part fixed thereto, when objectives are interchanged. The arrangement provides automatic focusing for objectives of one focal length only ; if an objective of different focal length is fitted, the objective must be separately adjusted in its mount in accordance with the distance of the object as determined by the telemeter. As shown, the objective A is carried by a mount B fitted at B<1>, as by a continuous or interrupted screw thread or a bayonet joint, into a flange C<1> on a member C which is in screw-threaded engagement at C<3> with a ring D fixed to the camera E and is provided with an arm C<2> whereby it may be rotated so as to produce axial focusing movement of the objective mount, this movement being communicated by the edge C<4> of the member C to a lever F connected to the movable mirror or other adjustable member of the telemeter (not shown). The edge C<4> may be flat as shown, oblique, or curved, as may be required to co-ordinate the focusing movement with the telemeter adjustment. The adjusting member C is left permanently on the camera, and when an objective is to be changed the objective mount is detached from the flange C<1> and is replaced by the new objective mount. Distance and focusing scales are provided on the ring D and the mount B for use when objectives are used for which the arrangement does not provide automatic focusing, as referred to above.
