Filed: 1954-01-07
Abstract: 757,415. Electromagnetic switches. ROTAX, Ltd. Jan. 6, 1955 [Jan. 7, 1954], No. 463/54. Class 38(5) A switch responsive to sustained but not transient overload and insensitive to acceleration, comprises a winding a on a non-magnetic bush b serving as a dashpot cylinder for two magnetic cores d, pole pieces c and an armature e completing the magnetic circuit. Springs f, g normally hold the cores in the position shown. A sufficient current in the winding a causes the cores to move towards each other with a delay produced by the dashpot action, the increased inductance of the magnetic circuit causing pivoting of the armature e against its spring j to close contacts h, i. An acceleration causes movement of the cores in the same direction and thus no change occurs in the magnetic circuit inductance.

Title: Improvements in or relating to fluid-tight valves especially for high pressures and temperatures
IPC: F16K1/34
Filed: 1931-01-08
Abstract: 370,451. Valve seats and faces. ZAGORSKI, J., 33, Kantstrasse, Berlin. Jan. 8, 1931, No. 681. [Class 135.] In valves for controlling the flow of fluids, especially at high pressures and temperatures, and of the kind comprising co-operating hard and soft metal seats, one of the seat members is made of a plastic and unelastic metal capable of resisting high temperatures, e.g. soft copper, soft iron, or alloys containing these metals, and completely or almost completely surrounded on three sides in a mounting or enclosure, while the other seat member is of hard steel and covers a relatively large proportion of the surface of the softer seat. In the construction shown in Fig. 1 a ring 2 of soft copper in the movable valve member 1 is adapted to be pressed against a relatively broad annular seat 3<1> formed directly on the hard steel diaphragm 3. Guide ribs 4 on the member 1 sliding in grooves on the valve body 5 prevent rotation of the valve, while the cover 6 fits against a soft copper ring 7. Other constructions are described in which the soft seating is formed on the fixed valve member, or may be sunk completely within or project slightly from its enclosure. In another arrangement, Fig. 10, the member 23 fitted with the hard seat 24 is formed with an integral cylindrical portion 25 adapted, in the closed position of the valve, to be spaced apart by a very narrow annular gap indicated at 26 from the member 21 containing the sunk soft-metal seat 22. This construction is suitable for the passage of fluids at high temperatures since, when the valve is slightly opened as shown, the point of constriction and of high velocity for the passage of the fluid occurs at the annular passage 26 between the hard body members 21, 25, the soft member 22 being entirely protected. In a modification the projecting annulus 25 is formed as an extension to one side of the enclosure for the soft metal.
