Title: Improvements in safety valves
IPC: F16K17/08
Filed: 1929-11-07
Abstract: 344,809. Fluid-actuated valves. DEHN, F. B., 103, Kingsway, London.- (Crosby Steam Gage & Valve Co. ; 10, Roland Street, Boston, U.S.A.) Nov. 7, 1929, No. 33998. [Class 135.] Safety valves.-A relief valve comprises an aperture or throat 1a, a valve seat 2 at the terminus thereof, a deflector sleeve 5 and an aperture closer 3 movable within and relative to said sleeve to expose the deflector 5 progressively as the closure member 3 recedes from the seat 2 in order to produce an increased reaction lifting pressure on the closure member which is urged towards the seat 2 by a spring 4 located above it. The effective orifice between the deflector 5 and the seat 2 at full opening is not less than the control orifice of the throat 1a and the deflector 5 is adjustable vertically and may be locked by a set-screw 7 engaging notches 5b in said deflector 5. In operation, static pressure in the throat 1a raises the closure member 3 slightly, whereupon expansion pressure of the escaping steam raises the member 3 still further, thus uncovering a part of the deflector 5 and deflecting the flow of'escaping fluid rearwardly and producing a reaction pressure on the closure member 3. This reaction pressure raises the valve member still further and enlarges the outlet passage between the deflector 5 and seat 2 so as to render the effective aperture of the throat 1a the controlling orifice. Three distinct pop actions are thus progressively obtained so giving a characteristic approaching a straight line lifting force. In a modification the closure member 3 is provided with an overhanging lip.

[Also in Division F4] The speed of a centrifuge motor 11, e.g. in a washing machine is controlled by supplying it with repeated bursts of A.C. (e.g. via a triac) which are influenced by a comparison between the output of a tachogenerator 12 and a reference signal, and a final speed n 2  is reached after at least one intermediate stage n 1 . The motor control is by an undisclosed, known device 13. As shown, the motor is accelerated at full power to n i , and then at full power again to n 2  after an interval determined by a timer 14. In a second embodiment Fig.2 (not shown) the separate timer is replaced by an RC circuit in the controller. In Fig.3 (not shown), acceleration to the final speed is initiated when the on/off ratio of the bursts of A.C. falls to a predetermined value (showing), that the load has also fallen). In Fig.4 (not shown), the reference value for the speed is gradually increased (by an RC circuit) to the value n 1 , whereupon it immediately increases to the value n 2 , producing maximum acceleration from n 1  to n 2  only. In Fig.5 (not shown), the arrangement of Figs. (3 and 4) are combined, the motor being gradually accelerated to the speed n 1  where it remains until the on/off ratio has dropped, causing maximum acceleration to n 2 . Transistor circuits for the on/off ratio detecting device and for varying the reference value are described Figs.6 and 7 (not shown). Also described are an arrangement for maintaining the speed at n 1  until a water level switch indicates sufficient water has drained away, and for switching it off or reducing its speed for a predetermined time if vibration or bearing forces are excessive. The speed n 1  is chosen to be below the critical speed range.
