Title: Improvements in or relating to screw-down stop valves
IPC: F16K31/50
Filed: 1958-07-02
Abstract: 885,208. Valves. CORNING GLASS WORKS. July 2, 1958 [July 3, 1957], No. 21205/58. Class 135. A screw-driven stop valve is actuated by a screwed spindle 25, Fig. 1. The closure member 15 is located in a pipe coupling housing 10 and co-operates with a seat 13 in the wall of an angular bore 12 of the housing 10. A yoke member 27, 28 is clamped to a flange 32 mounted on the housing by two pairs of bolts 34, 35 the latter of which also serve to locate a gland member 40, 41, 42, Fig. 3, which compresses a packing 37 against a shoulder 36 of the bore 12. The screwed actuating spindle 25 is carried by the yoke 27 and co-operates with an internally and externally screwed member 22 which passes through a collar 20 adhesively fixed to the hollow closure member 15 which carries an elastic ring 14 of a corrosion-resistant plastic. A compression spring 23 is retained between the collar 20 and a plastic cover 24 which is held in position by a nut 24a. A plastic protecting cover 50 fits over the yoke 27. On rotation of the spindle 25 the friction of the packing 37 prevents rotation of the closure member which thus moves axially towards or away from the seat 13. When the valve is closed a further rotation of the spindle 25 allows the spring 23 to press the closure member on to the seat.

Title: Improvements relating to the control of direct current electric motors
IPC: H02K47/16
Filed: 1932-07-27
Abstract: 403,464. Rotary transformers. PESTARINI, G. M., 4, Tapton House Road, Sheffield. July 27, 1932, No. 21209. [Class 35.] For preventing surges owing to voltage differences when a metadyne transformer is connected to a supply line, a stator winding is provided arranged to establish a magnetic flux in the rotor such that an electromotive force equal and opposite to the line voltage is developed at the primary brushes. A metadyne transformer is defined as a rotary machine transforming continuous current at constant voltage to a constant continuous current or to a current related to the voltage in accordance with a desired law. The rotor is driven at constant speed by an external motor or other means are provided by which the total power input is automatically adjusted to be equal to sum of the output and the losses at the desired speed. The machine shown is wound for two poles and has four polar salients. The primary brushes 3, 4 are in circuit with the trolley line T and earth G and the secondary brushes 5, 6 with the motors 8, 9. In Fig. 1, the poles 10, 11 carry windings 12, 13 connected to the mains through a switch 14. The field set up by these windings induces a voltage between the brushes 3, 4 when the armature 1 is rotated so that the main switch can be closed. No current flows in the secondary circuits 8, 9. In a modification, Fig. 2, the poles 15, 16 are provided with windings 17, 18 whereby an electromotive force is set up between the brushes 5, 6 and currents flow in the secondary circuits. These set up fluxes in the rotor which induce an electromotive force between the primary brushes 3, 4. The two methods described may be combined, the poles all carrying windings connected in series. After the counter-electromotive force of the transformer has been made equal to the line voltage, a relay may close or permit closure of the switch 7 or such a relay may give an indication that the voltages are equal. In another arrangement, the switch is closed a predetermined time after the energization of the stator windings. An adjustable impedance may be shunted across the switch 7 to limit current rush. In such a case, the machine may be connected to the line when at rest. The windings 12, 13 and 17, 18 may be similarly used and they may be connected in series with an additional adjustable impedance. The motors 8, 9 may be connected in series across the brushes 5, 6.

Title: Hydraulic brakes
IPC: F16K17/26
Filed: 1929-07-12
Abstract: 333,365. Coatalen, L. July 12, 1929. Fluid-pressure.-In hydraulic braking systems having separate pipes between the master cylinder or cylinders and the various brakes or sets of brakes the pressures in the separate pipes act normally in balance upon the opposite faces of a valve which at all times prevents communication between the two pipes and when subject to unbalanced pressures moves to obstruct the pipe line in which the pressure is lower, to prevent loss of oil should one pipe leak or break. The pipe lines 2, 2 and 3, 3 are connected with opposite ends of a valve chamber containing a floating valve 5 in the form of a piston restrained in its balanced position shown by a groove 11 engaged by a spring-pressed ball 12. If one pipe line fails the valve will move to close the appropriate outlet 9 or 10 preventing loss of oil and allowing the undamaged pipe line to function. The valve also closes the inlet pipe 7 or 8. To hold the valve at the end of its travel additional grooves 13 are arranged to be engaged by the ball 12. The ends of the valve chamber carry detachable caps 14, upon removal of which the valve can be pushed back to its central position. In a modification oppositely acting springs return the valve 5 to the central position and the valve acts only to cut off the supply at the inlets 7 or 8. The device may be used with the equalizing system described in Specification 331,700, the resistance of the spring-pressed ball 12 slightly exceeding any resistance in the equalizing device so that the pressure on the valve is normally always balanced.
