Title: Improvements in or relating to devices for measuring spring pressure for use in conjunction with electric contact-making relays, switches, or the like
IPC: G01N3/00
Filed: 1932-07-13
Abstract: 399,628. Dynamometers. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, ROBINSON, E. and NEVILLE, A. E., Ericsson Telephone Works, Beeston, Nottingham. July 13, 1932, No. 19769. [Class 106 (ii).] Comprises a device for measuring spring pressures, especially of springs used in electric contact making relays, in which a member adapted to be displaced from a position of stability when the force applied to it exceeds a predetermined value is adapted thereafter to continue its movement in the same direction without further increase in the applied force. A lever 1 is pivoted about a knifeedge 2 in a V-shaped groove in a block 3 fixed to the case 4 and is connected to a helical spring 5 by a hook 6 passing through the block 3. The lever 1 has a hole 7 in which is a knife edge 8 engaging the hook 6. The member 1 is slotted at 9 and the knife edge 2 is located in the groove in the block 3 between pins 10. The spring 5 is anchored to a block 11 adapted to be adjusted by screws 12 passing through clearance holes in a block 13 fixed to the casing. A covering plate 14 is secured to the block 13. The lever 1 is tapered and the lower end widened to form two points as shown. The !ever 1 carries a counterweight 17 so that it is balanced about the knife edge 2. The angular movement of the lever is limited by a member 16 fixed to the case 4 the lever coming against one or other of the inner cheeks of the member 16 which passes through the narrow portion of the hole 7. By suitably arranging the stops at the ends of the member 16 the device can be made to serve as a limit gauge, the force required to move the lever when applied to its extremity being the maximum, permissible or the minimum permissible according to whether the lever is moved from one stop or the other. The sliding block 11 may project through the casing and have a mark or pointer which indicates over a scale the force measured. One or both of the stops on the member 16 may be adjustable. In a modification the lever is pivoted about its centre of gravity and carries a roller at the upper end engaging a roller carried by one end of a lever pivoted to the frame and attached at the other end to a leaf spring bearing against an adjustable stop causing the lever roller to press on the roller on the first lever so that the lever bears against an adjustable stop. A third stop limits the motion of the lever when the latter is depressed.

Title: Method of and means for relieving pressure in gas containers
IPC: G21C13/10
Filed: 1962-05-24
Abstract: 932,878. Nuclear power plant. ALLMANNA SVENSKA ELEKTRISKA A.B. May 24, 1962 [May 26, 1961], No. 19956/62. Class 39 (4). A method of relieving pressure in a gas container containing gas under pressure, for example a gas container connected to a nuclear reactor and containing radioactive fission product gas, in which the main part of the gas is transferred to collecting vessels connected to the gas container, is characterized in that the gas container is connected to several collecting vessels with operable and closable connection conduits, and that the gas container is placed in open communication with one collecting vessel at a time and the open communication between the gas container and one collecting vessel is closed after the pressure in the gas container and the collecting vessel has become substantially equal, before the gas container is placed in open communication with another collecting vessel. In the arrangement shown a gas such as hydrogen, deuterium, oxygen or helium is introduced into the steam circuit of a boiling water reactor 1 and passes through condensers 4 and 11 before returning to the gas container 15 and pump 17. The container 15 is connected to a conduit 18 which can communicate through valves 21a-21g and 22a-22g with collecting vessels 19a-19g. If the pressure in container 15 is excessive, for example due to incomplete condensation in condenser 4, or if a leakage occurs in the gas system, the gas in container 15 is transferred to vessels 19a-19g by successively opening and closing valves 21 and 22; the valves may be controlled automatically by pressure sensing means in the container and in the vessels. The last container 19g may initially be at subatmospheric pressure so that the final pressure in. container 15 may be reduced below atmospheric pressure.

Abstract: 761,497. Printing-telegraph transmitters, CREED & CO., Ltd. (Lorenz Akt.-Ges., C.). July 9, 1954, No. 20153/54. Class 40 (3). In a tape-controlled telegraph transmitter the driving motor is controlled by a governor operating a lever which, until the motor reaches a predetermined operating speed, actuates contacts to short-circuit the transmitter contacts and also controls the tape-feed mechanism to prevent advancement of the tape. In the rest position, or until the motor has reached operating speed, a control magnet (not shown) is de-energized and a projection 15 on a lever 1 is out of contact with a pin 18 on one of two springs 2 so that contacts 19, 20 are closed and provide a short-circuit of the transmission line. A slide 4 pivotally connected to the lever 1 and movable in a guide 5 has a ledge portion 16 located immediately below the arm 7 of a lever 6 which is blocked against movement when the follower 10 engages the low portion 26 of a cam 8 on a shaft 9 of the transmitter. The lever 6 is connected by a rod 11 to an arm 12 carrying a pivoted pawl 13 by which the sprocket wheel 14 is stepped to feed the tape 17 when the lever 6 is actuated by the cam 8. The electromagnet, energized when the motor attains its operating speed, moves the lever 1 against the action of the spring 3 when the arm 7 is raised clear of the projection 22 above the ledge portion 16 on the slide by the high portion 21 of the cam which corresponds to the stop element 2 of the signal. The movement of the lever 1 opens contacts 19, 20 thereby removing the short circuit of the line, and also allows the lever 6 to operate the tape-feeding mechanism. When the motor slows down at the end of transmission, the magnet de-energizes and the spring 3 is able to rotate the lever 1 to the position shown when the high portion of the cam 8 raises the arm 7 clear of the projection 22 on the member formed on the slide 4.
