Title: Activation of electric dry batteries
IPC: H01M6/32
Filed: 1954-06-28
Abstract: 756,998. Batteries. BAUER, R. E. June 28, 1954 [July 15, 1953], No. 18831/54. Class 53. [Also in Group XXVIII] A dry battery is activated by introducing a predetermined amount of water into a vessel placing the battery in the water closing the vessel and reducing the air pressure to withdraw air from the battery and then increasing the pressure to force water into the battery. The process is carried out by the apparatus shown in Fig. 3 in which 10 is the vessel containing water 12 into which the battery 13 is immersed. A predetermined quantity of water is admitted into the vessel 10 by means of passages 28, 37 leading to a receptacle 50 which is fed with water from a closed container 55. The level of the water in the receptacle 50 can be adjusted by adjusting the height of the container 55 by means of threaded bolts 57. The battery is suspended in a holder 14 attached to the lid 15 of the vessel 10. The lid is pivotally attached at 17 to an arm 18 to which is pivoted a stirrup 39 which carries a valve 29 at its lower end. When the lid 15 is in its raised position as shown in Fig. 3 the valve 29 is opened and water flows from the receptacle 50 into the vessel 10. A spring catch 47 holds the arm 18 in the raised position. When the levels of the water in 10 and 50 have become equalized the arm 18 is lowered by a handle 21 to close the vessel 10 and the valve 29 and to immerse the battery in the water 12. The lid 15 is held in the closed position by a catch 22. Air is now removed from the vessel by one stroke of a pump attached to a tube 25, the pressure being indicated by a gauge 26. - A glas window 27 in the lid enables air bubbles released from the battery to be seen. When air ceases to be withdrawn from the battery the air which has been removed from the vessel is returned and the vessel is then opened and the battery removed. The mouth of the container 55 is closed by a valve 63 when the container is removed for replenishing with water and when inverted. When fixed in position as shown in Fig. 3 the stem 62 abuts against the support 53 and opens the valve. A foot-operated pump which at a single stroke removes air from the vessel 10 and forces it back on the return stroke is shown in Fig. 6. A cylinder 70 pivoted at 71 to a frame 72 encloses a piston, the rod 74 of which carries a bracket 77 pivoted at each end to a member 80. Each member 80 is pivoted at 84 to an arm 82 hinged at its lower end to the frame 72. The arms carry a foot-plate 83 and the members 80 are further pivoted at 85 to links 81 pivoted to the frame. The extent to which the plate 83 can be depressed, and hence the stroke of the piston, is determined by the position of an adjustable stop 86 with which the arm 82 engages when the plate 83 is depressed.

Title: Improvements in speed limiting devices for turbines
IPC: F01D17/14
Filed: 1955-07-01
Abstract: 777,008. Turbines. GENERAL ELECTRIC CO. July 1, 1955 [July 1, 1954], No. 19160/55. Class 110 (3). A turbine having speed-limiting means comprising a movable member adapted to permit flow of working fluid through the rotor in one position and to interrupt the flow in a second position and means biasing the member to the first position also has means for causing the member to move to the second position against the biasing means in response to windage torque only when the torque exceeds a predetermined magnitude. Windage torque is the torque exerted by the rotary motion of gases which are set in motion by the turbine disc. A turbinetype starter motor comprises a rotor 2, supported by bearings 3 in a casing 4, which is connected to the engine to be started through a shaft 5, pinion 6, reduction gearing and a clutch. Working fluid is supplied to the rotor through a nozzle box 10 and nozzles 11. To restrict the flow of gases from the nozzles 11 through the turbine blades 12, an annular nozzle control plate 13 is provided. This control plate is mounted on a bearing 14 and biased by a spring 16 into the position shown in Fig. 2 in which openings 15 in the plate are aligned with the nozzles 11. The nozzle plate may be located against axial movement by making it co-operate with suitable rabbeted portions in the casing 1 as described in Specification 624,223. Suitable stops (not shown) are provided to limit the angular movement of the plate. When the rotor 2 is in motion it causes the gases between the plate 13 and rotor 2 to rotate. The gases impart a windage torque to the plate 13 which increases with increase of rotor speed. If the rotor speed becomes excessive, the plate 13 moves against the action of spring 16 and the openings 15 are moved out of alignment with the nozzles 11 so causing the working fluid to flow around the rotor into the exhaust casing 8. Projections 18 on the back of the plate 13 enable the flow of gas to hold the plate against the action of the spring. Small vanes 17 may be provided on the rotor 2 or plate 13 or both to increase the windage torque.
