Abstract: 689,988. Screwing-up and unscrewing nuts. HOLMAN BROS., Ltd., and COOMBES, F. B. Oct. 8, 1951 [Oct. 12, 1950], No. 24961/50. Class 83 (iii). An impact wrench comprises a driving member 16 driven from a reversible pneumatic or other motor 10 through epicyclic reducing gearing 15, a hammer 18 journalled for axial and rotational movement on an extension 16a of the driving member and an anvil 19 carrying a socket 21. The driving member and hammer interfit to form a fluidtight space 31 to which fluid, such as the compressed air for the motor, is admitted through a bore 28, spring-loaded non-return valve 32 and bore 30, the initial pressure in the space 31 being adjustable to any value up to that of the motor air supply by a screwed rod 34. When the resistance of the nut being driven exceeds a pre-determined value, the rotation of the hammer and anvil is arrested but the driving member continues to rotate so that balls 27 in cam tracks on collars 24, 26 fixed to the driving member and hammer cause the anvil to move up. This upward movement disengages dogs 22 on the hammer from dogs 23 on the anvil and compresses the fluid in the space 31, the energy stored in the compressed fluid being re-applied to the hammer so that it strikes a blow on the anvil when it is forced down to re-engage the dogs again. Both collars may have cam-tracks of constant or varying slope or one of them may be merely a flat thrust-plate.

Filed: 1954-08-30
Abstract: 774,812. Pressure-relieving devices for fluids. JOHNSON, MATTHEY & CO., Ltd. Aug. 9, 1955 [Aug. 30, 1954], No. 25156/54. Class 135. A vacuum support for a domed disc 3 which is adapted to burst on the attainment of a predetermined pressure on the concave side thereof consists of a domed member 2 shaped to fit exactly the member 3 and provided with apertures 5 to allow access of the pressure to the member 3, the member 2 having radial slits 7 so that if, after bursting of the disc 3, the holes 5 present such a resistance to flow as to prevent adequate release of pressure the member 2 opens up to allow unrestricted flow. The member 2 is formed initially with a slightly more domed contour than is required in the finished member so that after the formation of the holes 5 and the radial slits 7 the member can be pressed downwardly to the required shape in which process the edges of the radial slits are pressed into tight engagement with each other. This process is facilitated by the truncating of the apex of each of the sectors 6 formed by the radial slits. A thin piece of foil, e.g. silver, 12, soldered in position, retains the sectors in mutual alignment and ruptures to allow the member 2 to open. An arcuate slit 7a is associated with each radial slit to facilitate bending of the sectors 6. The member 2 may be made, e.g., of nickel.

Title: Improvements in or relating to electric switches with arc extinction by self generated vapour pressure
IPC: H01H33/98
Filed: 1931-09-10
Abstract: 393,927. High-tension switches. SIEMENS-SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. Sept. 10, 1931, No. 25433. Convention date, Nov. 27, 1930. Void [Published under Sect. 91 of the Acts]. [Class 38 (v).] In an " expansion " switch in which the arc vaporizes a liquid and is extinguished by suddenly expanding the vapour and causing its condensation, a second break in series is provided and the pressure developed in the expansion chamber blows the liquid across this second gap. As shown in Fig. 2, the fixed contact in the liquid (e.g. water) within the expansion chamber is engaged in the closed position by an intermediate spring- controlled contact 3 which is moved into the closed position by upward movement of the hollow movable contact 2. When the contact 2 is moved downwards to break the circuit, the intermediate contact follows and an arc is drawn in the liquid whereby pressure is developed. After a certain movement, the contact 3 is held up by the bracket 7 and the movable contact leaves it, whereupon the liquid under pressure is blown across the second gap and the relief of the pressure ensures the extinction of the arc at the first gap. The intermediate contact may be hollow and may move into a bell-like housing above which the expansion liquid is located. In the form shown in Fig. 5, which is particularly applicable to switches using water as the quenching liquid, the expansion action takes place between the fixed and intermediate contacts 2, 3 in an inner chamber 4. The movement of the middle contact is arrested and a second arc gap drawn as the contactmember 2 moves upwards out of the container '8. The pressure is thus relieved, the first arc extinguished by expansion action and the second by the rush of oil across the gap. The upper contacts may be arranged in a separate upper chamber to extinguish the second arc on the expansion principle.
