Title: Thermal actuator
IPC: F03G7/06
Filed: 1972-09-22
Abstract: 1381558 Thermal responsive devices DANFOSS AS 22 Sept 1972 [22 Sept 1971] 43978/72 Heading G1D [Also in Division F2]  A thermal actuator for a valve 6, 7, has formed therein a working chamber A containing a vaporizable liquid 21 and an equalizing chamber B, the two chambers being in selective communication with one another by way of an aperture-defining seat 14 and the channels formed in a valving- member 15, such channels being defined by the polygonal cross-section of the valving-member and being in communication with transverse passages 16. The stem 5 of main valve-member 6, is connected to an interior housing 11 which depends from a bellows 4 and which houses an electromagnetic coil for actuating valving-member 15. The lowermost portion of housing 11 carries an electric heater coil 17. In the state of the actuator shown, the two chambers A and B are in communication with one another and so there is no net pressure differential across the bellows wall 3, there being, in such circumstances, a net downward force on valve stem 5 due to the action of spring 12. On activating the heater 17 and closing magnetic valve 14, 15, the vaporizable liquid 21 (e.g. a fluorochlorohydrocarbon) becomes heated and the vapour thereby generated eventually produces a force greater than, and opposite to, the force of spring 12, thus opening valve 6. If the latter is then to be closed rapidly, magnetic valve 14, 15 is opened and so the pressure in chambers A and B becomes equalized thereby rendering spring 12 effective in rapidly moving closure member 6 into engagement with seat 7. On condensing in chamber B, the condensed vapour flows back into chamber A via passages 16, possibly assisted by a small pump. A pressure sensor 20 cuts-off the current to heater 17 when the pressure exceeds a predetermined value. Alternatively a limit position switch may be used. In a modification Fig. 2 (not shown) the chambers A, B are separated by a rolling diaphragm (29) supporting a movable wall (33) which is frusto-conical to direct condensed vapour from chamber B back to chamber A. Parts of the electromagnetic valve (35) and parts (23, 24) of the actuator housing may be of moulded plastics material, whereas the top (25) of chamber B is of metal to assist condensation.

Title: Improvements in or relating to apparatus for controlling a fluid power motor
IPC: F15B11/08
Filed: 1962-11-22
Abstract: 1,034,108. Hydraulic apparatus. APPLIED POWER INDUSTRIES, Inc. Nov. 22, 1962 [Nov. 22, 1961], No. 44224/62. Heading F1P. An hydraulic piston 2 Fig. 1 (not shown) is held in any position under load by closing exhaust valves 32, 44 and supply valves 46, 48 in lines 50, 54 connected to opposite ends 51, 52 of the cylinder 3, and during such holding period delivery from a continuously running pump 4 is by-passed to an exhaust reservoir 5 past a valve 16 held open by the stem 20 of a downwardly biased piston 18 and past an open solenoid valve 8. Valves 32, 48 are held closed by a spring 39 surrounding the stem of a plunger 88 Figs. 2, 3 (not shown) of such length as to allow limited axial play whereby valve 48 can be opened by high supply pressure and valve 32 opened by downward displacement of the stem 38 of a piston 36 when the latter is urged downwardly against a spring 37 by hydraulic pressure build-up in a pilot line 26. Valves 44, 46 are of similar construction but the piston stem 42 serving to open valve 44 is biased to the open position by its spring 41 and is displaced to the valve-closing position by pressure build up in a pilot line 30 leading to the underside of piston 40. During holding periods solenoid valves 8, 12 are open and valve 10 is closed, during a piston advance period against load valves 8, 12 are closed and valve 10 is open whereas during return under load valves 8, 10 are closed, and valve 12 is open. At the start of piston advance, pressure from a line 6 builds up in pilot line 24 sufficient to lift piston 18 and allow valve 16 to close. Fluid pressure then opens a check valve 14 and supply valve 48 to enter line 50; line 54 being connected to exhaust 5 past valve 44 which is held open by piston stem 42 since the space below piston 40 is connected to exhaust 5 through pilot line 30 and open valve 10. On opening valve 12 and closing valves 8, 10 to effect piston return under load valve 32 becomes unseated by pilot pressure in line 26, valve 48 is held on its seat, valve 44 is allowed to be seated by spring 86 since piston 40 is lifted by pilot pressure build-up in line 30 whereupon full hydraulic pressure then opens valve 46 and is admitted through line 54 to the return side of the piston 2. High pressure relief valves 17, 62, 64 and low pressure relief valves 66, 68 are provided. In a modification for use with a single acting piston cylinder 3a, Fig. 1a (not shown) the union connecting valves 48, 32 to the line leading to the load end of the cylinder is permanently blocked, solenoid valve 12 is maintained always open. Piston advance is effected by the solenoid valve settings for retracting a double acting piston whilst piston return is effected by opening valves 8, 10. The various valves are assembled in a common block 70 as are fluid flow lines and pressure relief valves.

Abstract: 1,022,119. Pulse radar. NORTH AMERICAN AVIATION Inc. Dec. 20, 1961, No. 45705/61. Heading H4D. A monopulse radar, mounted in a low-flying aircraft, provides a display of the range of obstacles above a selected clearance plane as described in Specification 1,022,120. Warning signals are developed which intensity modulate the P.P.I. display to brighten the obstacle representation and which are formed in accordance with the expression where R = obstacle range h 0  = present clearance E s  = radar sum signal E D  = radar difference signal K = constant. The expression (1) incorporates the feature that the centre line of the antenna beam pattern and the clearance plane intersect at a selected range. Antenna azimuth control may be provided by a programmer and both elevation and azimuth antenna control signals are applied through a roll resolver. Where the system is employed for mapping a pitch pick-off from a gyro-vertical is employed to provide the horizontal reference. Automatic gain control is provided to allow for range and obstacle reflectivity. A sawtooth range sweep voltage is provided by a display vertical deflection circuit controlled from the transmitter trigger. The sweep generator (Fig. 6, not shown), comprises a pentode having capacitive feed-lock to the control grid. The trigger pulse is supplied to the screen grid together with a bias voltage. The range sweep voltage at the pentode plate is applied to the control grids of a dual triode to provide at the dual anodes, positive and negative range signals simultaneously. The latter are applied respectively to the control grids of the pentodes forming a multiplier. The suppressor grids of the pentodes are supplied with signals of the form of the parenthesis in expression 1. The net pulse gain at the plates changes linearly in proportion to the sawtooth voltage at the control grid and this voltage is therefore proportional to the product of range and the bracket expression in expression 1.
