Title: Improvements in or relating to ship stabilizers
IPC: G05D1/08
Filed: 1928-09-04
Abstract: 320,478. Hammond, J. H. Sept. 4, 1928. Rolling motion of ships, damping.-In installations for minimizing the rolling or pitching of ships comprising tanks containing a stabilizing fluid, such as sea water, connections containing a control fluid such as air, are provided and means operated in accordance with the angular roll or pitch of the ship regulate the flow of the control fluid and hence the amount of stabilizing fluid in the tanks. On each side of the ship tanks 23, 24 are provided with bottom orifices 26, 27 open to the sea. The tops of the tanks are connected by pipes 28-30. Control gear 32 is centrally disposed and comprises flap valves 40, Fig. 2, in each pipe controlled' by spring-actuated detents 45 operated by the energization of solenoids 46, 47 electrically connected to studs 56, 61, 65 and 59, 63, 66. The respective sets of solenoids are energized by the rocking of a member 71 carrying fingers which contact with the studs, the release of the detent 44 or 45 the valve to swing in one direction or the other. The rocking of the member 72 occurs when one of a pair 77, 78 of oppositely-disposed solenoids is energized. These solenoids are in electrical connection with the system shown in Fig. 4 which includes a gyroscope 84, the gimbals of which carry arms 93, 110, carrying rollers 94, 111. These rollers work on segments 125 which are geared up with an electric motor 132 which is brought into play if the rollers, through rolling of the ship, are displaced from. their central position on the segments 125. The movements of the shaft 131 are also transmitted through electrical repeater-mechanisms to the shaft 161 of a governor 177 which controls an arm 181 which thus moves at a rate proportional to the speed of the ship across segments 184, 183, 182 thus successively connecting the conductor 203 with the conductors 202, 201 and 200 and closing in successive order the circuits of the magnets controlling the valves in the pipes 30-28 on the energization of the magnets, successively releasing the. detents which normally lock the flap valves. This allows the air, which in the event of a roll to the right-has been compressed in the tank 24, to pass through the pipes 28-30 into the tank 23 which is under reduced pressure. In this way the pressure in the opposite tanks is gradually equalized as the ship approaches its position of maximum roll. The resulting movement of water in the tanks produces a turning moment in opposition to the roll of the ship. The position of the sectors 184 may be adjusted by hand through suitable gearing to allow the point at which the valves are open to be adjusted. In a modification, the gyroscopic control unit is replaced by a pressure control unit in the form of a sensitive pressure gauge. In another form, in which a single pipe connects the tanks a damped pendulum acts as the control unit.

Title: Catch for longitudinally slidable window
Inventor: LEONARD BRIAN WILLIAM
IPC: E05C3/24
Filed: 1964-06-19
Abstract: 1,026,189. Latch for sliding windows. FORD MOTOR CO., Ltd. June 19, 1964, No. 25413/64. Heading E2A. A catch for a slidable window 7 comprises a rotary catch plate 3 carried on the inner surface of the windows, a stationary striker 29 which when the window is moved in the closing direction engages the catch plate to rotate it to a position in which it is locked against further rotation and the striker, by engagement with the plate prevents movement of the window in the opening direction and a device for unlocking the plate so as to permit opening of the window. A base plate 5 is bonded to the inner surface of the window, the base plate having an integral pivot 9 and an opening 11. Rotatably mounted on the pivot 9 is the catch plate 3 which has a peripheral opening 15 aligned with opening 11 and peripheral teeth 17, 19. A knob 1 is also rotatable on the pivot 9 and has an opening 21 aligned with openings 11, 15. Within the aligned openings 11, 15 and 21 there is an insert 27. In the open position the nearest tooth 19 is above a horizontal line through the top of the striker. As the window is closed, the inner surface 17<SP>1</SP> of the tooth 17 contacts the striker so that continued movement of the window rotates the catch plate in a clockwise sense. The rotation of the catch plate causes the insert to slide in opening 11 until it contacts the end and so prevents further rotation of the catch plate. Rotation of the knob 1 in this position (Fig. 2) causes the insert to contact the abutment surface 13 of the base plate opening 11 thus preventing rotation of the catch plate. When the knob 1 is rotated counterclockwise the insert is moved away from abutment 13 allowing the window to be opened. In another embodiment the pivot 9 is tubular with a headed steel pin down its centre which passes through an opening in the window.
