Title: Electrically actuated rotary fluid valve for zone heat control
IPC: F16K31/04
Filed: 1958-10-09
Abstract: 886,631. Automatic temperature control systems. DOANE, D. B. Oct. 9, 1958, No. 32231/58. Class 38 (4). [Also in Groups XXIX and XXXVII] An electrically-operated rotary valve comprises a valve 11, Fig. 1, controlling flow through the body 10, a base-plate 25, Fig. 3, removably attached to the body and carrying a unidirectional electric motor 64 mounted on a terminal plate 43 and a rotary switch 55, and a motor shaft extending through the terminal plates and through and connected, e.g. by enlargement 77 engaging opening 75, to the rotary switch into a driving engagement, e.g. via tongue and slot 78, 33, with the valve stem 33 for unidirectional co-rotation of the switch and the valve. On heat demand thermostatic switch 93, Fig. 6, connects with contact 92 and current flows from a transformer secondary coil 90 via a conductor 80 continually in contact with the rotor 72 of the switch, and via rotor arm 87 connecting contact 79 through the motor 89 which then begins to open the valve and turn rotor 72 via reduction gearing 65. When the valve is partially open rotor arm 87 engages contacts 81 whereby current flows through a relay 97 for operating a pump circulating heating medium through the valve. When the valve is fully open arm 87 leaves contact 79 and engages contact 82 and motor 89 stops. When the heat demand is satisfied switch 93 returns to contact 94 whereby current flows via contact 80, rotor 72, arm 87 engaging contact 82 so that motor 89 continues rotating in the same direction until arm 87 leaves contact 81 to stop the circulating pump and when the valve is closed arm 87 leaves contact 82 and diametrically opposite arm 88 engages contact 79 preparatory to operating the valve on a further heat demand. The base-plate has brackets 30, 31 engaging ears 22, 23 on the valve body to hold the plate in position and close a plate 35 located on the base-plates by a bridge 34 which engages a notch 32 in the valve stem to retain the valve in the body.

Patent GB-873928-A (GB)
Title: Improvements in and relating to sample introduction devices for vacuum analysing apparatus
IPC: H01J49/04
Filed: 1959-09-24
Abstract: A glass capillary tube 1 is high-vacuum sealed by means of a valve flange 2 and a cellar 3 of synthetic plastic material to a valve casing 4 having a cylindrical hole 5 in such manner that the lower orifice of the glass capillary interchangeably fits the cylindrical hole 5 of said valve casing.  The resilient diaphragm 6 is stretched and fixed to the valve casing by a flange 7 and its middle portion is pressed on the lower orifice of the glass capillary by knurled screw 8 which will close or open said orifice at will.  Fig. 2, <PICT:0873928/III/1> not shown, illustrates further embodiment of a sample introduction system according to the invention in detail. During normal use of the sample introduction system the apparatus, as described above, is fitted to the inlet system of the mass spectrometer by means of a flange 10.  The capillary section remains closed.  The system is now evacuated by aid of a pump.  A glass pipette containing a determined quantity of the sample to be analyzed is then placed on the upper orifice 13 of the glass capillary section whereupon the lower orifice 14 of the capillary section is opened by turning the knurled screw in a counter-clockwise direction.  Due to the fact that the system is under vacuum the liquid is sucked into the capillary section.  As soon as the capillary section is filled, the glass pipette is removed.  When the liquid level has reached one of the upper markings 11, the lower orifice 14 of the capillary section is closed.  Now the cavity 5 is evacuated again, the vacuum pump is then stopped and the inlet system is now connected via a valve to the inlet system of the spectrometer. By turning the knurled screw 8 the capillary is opened again, the fluid is sucked into the lower portion of the capillary and evaporates at the inner walls of the cavity, due to the fact that the casing is normally heated up by aid of heating members clamped to the outside of the cavity.  When the liquid level has reached one of the lower markings 11, the capillary is closed again.

Abstract: 1,177,217. Valves. BROCKHOUSE HEATER CO. Ltd. 10 Oct., 1967 [21 July, 1966], No. 32714/66. Heading F2V. A valve, which can be used for regulating or relieving fluid pressure, comprises a cylindrical chamber 11, inlet and outlet connections 32, 33 respectively, a cage member 22 which is integral with a piston 28 movable within the chamber bore 18 and having a passage 19 and seat 20, and a stem 15 having one of its ends provided with a reduced diameter portion 25 which is adapted to enter with clearance the bore 19, and its other end provided with a head 30 which is adapted for engagement by a cam 31. In operation as a pressure regulator, the cam-operated stem is movable upwardly or downwardly so determining the extent to which the piston 28 has to be moved by fluid pressure at the inlet before a ball-type valve member 21, normally forced by the inlet pressure against the seat 20, is unseated as a result of the reduced diameter portion 25 entering the bore 19 and engaging the ball. In operation as a pressure relief valve, the stem is moved to a given position which determines the pressure at the inlet necessary to move the piston far enough for the ball to be moved from its seat and hence pressure relieved. In an alternative embodiment, spring 26 may be replaced by a damper disposed in a fluid duct and connected to the piston, the position of the damper in the duct determining the load on the piston.

Title: Improvements in or relating to voltage regulating arrangements
Inventor: GRAHAM JOHN ST CLARE WILLIAM
IPC: G05F1/34
Filed: 1949-12-22
Abstract: 667,246. Automatic voltage control systems; charging batteries. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Dec. 4, 1950 [Dec. 22, 1949], No. 32802/49. Class 38 (iv). In automatic voltage regulating apparatus voltages corresponding to voltage deviations are amplified and applied to the control winding of a magnetic amplifier, the output of which is injected into the supply circuit to provide the required correction. A storage battery EB supplies bus-bars 10, 11 and an ampere-hour meter AH operates a contact ah1 when the battery is, say, 25 per cent discharged, to energize a self-holding relay AHA, a contact aha2 of which energizes the D.C. winding of a saturable reactor SC to reduce the impedance in series with the A.C. supply from a mains transformer TRA to a rectifier RB1 so that the rectifier output, which charges the battery through smoothing circuit SC1, is raised from a trickle charge to full charge level. The ampere-hour meter then runs in the reverse direction to operate a contact ah2, when charging is complete, to short-circuit the winding of relay AHA and restore trickle charge conditions. In Fig. 2 (not shown) the ampere-hour meter drives a condenser in series with a cold cathode discharge tube which fires at a predetermined state of discharge of the battery to cause energization of saturable reactor SC. To maintain constant the voltage of bus-bars 10, 11, e.g. in a telephone exchange, a bridge circuit VB containing linear and non-linear resistors becomes unbalanced on voltage deviation to energize saturating windings A, B of a biased push-pull magnetic amplifier MA1, a protion of the D.C. output of which, across resistors YC, YD, energizes the saturating winding of a second biased magnetic amplifier MA2, the D.C. output of which, from a rectifier RB2, is injected in series, aiding the supply to bus-bars 10, 11 so as to correct the voltage deviation. Variations of bus-bar voltage caused by changes of load and charging of the battery are respectively directly compensated by windings H, G of magnetic amplifier MA2 which are energized by the volt-drops across resistors YF, YE in the battery discharging and charging circuits, respectively. Use of a push-pull magnetic amplifier in place of magnetic amplifier MA2 to provide bucking or boosting of battery voltage is referred to.
