Title: Control systems for gas burning appliances
Inventor: COX GEOFFREY EDWARD
IPC: F23N5/10
Filed: 1954-07-05
Abstract: 796,314. Fluid-pressure servomotor-control systems. DE LA RUE & CO., Ltd., T. June 29, 1955 [July 5, 1954; April 14, 1955], Nos. 19649/54 and 10795/55. Class 135. A control system for gasburning appliances has the main gas flow controlled by a pressure-operated relay valve 13 in a first compartment 8 in the main gas flow separated by a wall 6 from a second compartment 10 containing a weighted diaphragm 9 attached to the valve spindle 12 passing sealingly through the wall 6, the valve being opened and held open by a flow of gas through a weep line 16, 24, 39, 14 and 14 from the main gas supply 1 on the inlet side of the relay valve to the second compartment beneath the diaphragm, and closed by interruption of the weep flow by closure of a primary control valve, e.g. 25, 19, 38 or a clockoperated valve on the inlet side of the relay valve. With the burner cock 5 closed a button 34 is depressed to close the valve 36, open a valve 33 and bring an armature 31 into contact with an electromagnet 28. Gas passing at 16 through valve 33 to the pilot burner 30 is ignited to heat a thermopile 29 which energizes magnet 28 to hold valve 33 open. On depressing valve 20 gas at 16 flows passt valves 33, 36 to act beneath the diaphragm of and open a pressure cut-off valve 21. With the thermal element 38 cold and its valve open the weep flow of gas then passes at 24 through this valve to pipe 39, beneath the diaphragm 9 and through a diaphragm orifice 14 to a waste burner 40. Gas also passes via throttle 23a to the space between the valve 13 and the cock 5. If the latter is closed, pressure in chamber 10 is sufficient to open valve 13. On opening cock 5 the main burner 2 is ignited by the pilot burner 30. In a modification a separate pilot burner is taken directly from the mains so that the pipe 37 and valve 36 are dispensed with, and the pressure regulating valve 18, lowpressure cut-off valve 19 and weep pipe 23 are also dispensed with. An adjustable screw may be provided to prevent the valve 13 closing completely. In a further modification the weep pipe 23 taken from upstream of the thermostat 38 and down stream of all other controls in the weak pipe and including a clock-controlled valve, is provided with an adjustable screw throttle so that the valve 13 opens and closes with the thermostatic valve 38 and the cock 5 becomes unnecessary.

Title: Improvements in or relating to lawn mowers
IPC: A01D34/42
Filed: 1924-08-20
Abstract: 243,062. Morgan, T. Aug. 20, 1924. Lawn-mowers.-The stationary blade is acted upon by means which automatically advance its cutting-edge towards the rotary cutter but positively resist movement in the contrary direction. The stationary blade 2 is carried by an angular bar 3 pivotally mounted at its ends on pivots enclosed in grease boxes. On it is an arm 7 pivotally connected to an H-shaped link 8 carrying a recessed pin 9 passing through a cylinder 10 rotatable on it. In the cylinder 10 slides a rod 11 fastened to a pivot pin 13 carried by a shield plate 14 fixed between side plates 6. Between the cylinder and an adjustable nut 12 on the rod 11 is a spring which continually presses the blade 2 against the rotary cutter 1. Downward pressure on the blade 2 tends to turn the pin 9 into the position shown in Fig. 4 thus causing one of its edges to engage the rod 11 and prevent forward movement of the arm 7, and downward movement of the blade 2. By turning the nut 12 the pressure between the blade 2 and cutter 1 may be regulated. Sufficient pressure may be applied to cause a hard blade 2 to grind the cutter 1. The shield plate 14 may be dispensed with and the outer end of the rod 11 carried by a cross-bar. The blade 2 may be provided with two arms 7 and controlling-devices. According to one Provisional Specification a recessed pin is operated by a lever engaging an incline on an arm on the bar carrying the stationary blade; the pin being mounted in a spring-pressed sleeve surrounding a tubular rod on which the pin binds to prevent downward moyement of the stationary blade. According to the other Provisional Specification a spring-controlled pivoted member carries a brake shoe or member bearing on an inclined or cam-shaped surface on the arm on the blade carrier; or the brake member is pivoted to a spring-pressed carrier sliding on a vertical rod. The arm on the blade carrier may be a stiff spring.

Abstract: 396,547. Wireless control of distant apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Alexanderson, E. F. W. ; 8, Adams Road, Schenectady, New York, U.S.A.) July 14, 1932, No. 19983. Convention date, July 15, 1931. [Class 40 (v).] An aircraft or other moving craft is steered automatically in accordance with a course determined by a magnetic compass and also in accordance with signals received from a radio beacon when the craft drifts from the course. An earth inductor compass is used and gyroscopic means are provided for correcting for the vertical component of the earth's magnetic field due to tilting of the compass platform during a turn. An inductor compass 1 has its armature connected in circuit with an indicating instrument 4, resistances 6, 7 and the winding of a polarized relay 5. The relay co-operates with contacts connected through low resistances to the grids of two thermionic valves 15, 16 which are normally negatively biassed by a battery 22 through high resistances 23, 24. When one or other contact is closed, anode current is caused to flow through the corresponding valve to energize one or other of two windings 13, 14 of a reversible clutch which connects a motor 9 to worm gear 11 for turning a rudder 8. The signals from a radio beacon of the kind modulated to different frequencies on the two sides of the determined direction are picked up by an aerial 44 and the detected signals are fed to two windings 50, 51 around magnets having reeds 48, 49 tuned to the two frequencies. The output from two windings 52, 53 on opposed magnets is rectified and fed to an instrument 56 connected across a part of the resistance 6. Normally no current flows through the instrument 56 but should the craft drift off its course a voltage is applied across the part of the resistance 6 and the relay 5 is actuated.

Title: Improvements in or relating to electromagnetic measuring instruments
IPC: G01D5/22
Filed: 1950-08-11
Abstract: 691,384. Transformers. GENERAL ELECTRIC CO., Ltd., MATTHEWS, A., and POLGREEN, G. R. July 30, 1951 [Aug. 11, 1950], No. 20029/50. Class 38 (ii). [Also in Group XXXVIII] An electro-magnetic pick-up head for measuring small displacements comprises two symmetrical transformers totally enclosed by an iron dust core except for two or more short air gaps which are varied by movement of a movable part of the core, the change in inductance of the secondary windings being indicative of the magnitude of the displacement. An embodiment for measuring pressure (Fig. 1) comprises a diaphragm 1 rigidly clamped at the outer edge and supporting two metal discs 5 at the centre, dividing a gas-tight chamber into two sections 6, 7, the forward section 7 being connected via a tube 8 to the space whose pressure is to be determined, and the other section 6 being evacuated. The discs 5 are assembled on a metal rod 9, carrying the movable parts 26, 27 of an iron dust core totally enclosing two spools carrying two primary windings 43 and two secondary windings 42. Air gaps 30, 31 are allowed between the movable cores 26, 27 and fixed cores 18, 19 separa.teci by a phosphor-bronze spider 22, which prevents lateral movement of cores 18, 19, the air gaps 30, 31 being adjustable by a metal cap 33 threaded on to the rod 9, altering the position of a metal sleeve 34 carrying the movable cores 26, 27. A gas-tight bellows 11 allows for longitudinal movement of the rod 9 while maintaining the vacuum in section 6. The two primary windings 43 are connected in series aiding and fed with A.G., the two secondary windings 42 being connected in series opposition across a milliammeter. The gaps 30, 31 are initially balanced by adjusting the cap 33, and subsequent movement of the diaphragm 1 produces a proportionate reading on the milliammeter. In a modification (Fig. 4) for more general use, the rod 9 is supplied with a tapped end 49 for coupling to any moving part, and a resistance winding 56 is assembled inside the head to provide temperature compensation. An over-travel alarm is also provided by the addition of an adjustable end stop 58 screwed into the casing, and closing an alarm circuit when rod 9 contacts the casing. The pick-up head may be employed in the arrangements described in Specification 677,355, [Group XXXVIII].

Title: Improvements in and relating to circuits for controlling the ignition of gas-filled and/or vapour-filled electric discharge tubes
IPC: G05B11/01
Filed: 1953-07-20
Abstract: 742,956. Rectifying; control systems for consumption apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 20, 1953 [July 23, 1952], No. 20051/53. Classes 38 (2) and 38 (4). [Also in Group XXXVII] For controlling the supply of energy to a load 9 from an A.C. source 10, 11, a grid of a gas or vapour-discharge valve 8 is energized with a variable alternating voltage derived from a variable-mu multigrid high vacuum discharge valve 1 to a grid of which is supplied a constant alternating voltage from transformer 3 together with a variable direct control voltage applied between terminals 5, 6. The valve 8 may be a, simple rectifier, Fig. 1 (not shown), or as shown in Fig. 4 may be one of a pair 8, 16 connected back to back to control the supply of A.C. to load 9 such as a lighting circuit or an electric furnace. Both valves 8, 16 have two grids, one supplied from a secondary winding of transformer 7 with the controlled A.C. output from valve 1 in phase with the anode volts, and the other supplied from transformer 14 or 19 through phase-changing circuits comprising capacitors 13, 18 and resistors 12, 17 with voltage displaced by 90 degrees from the anode voltage supplied from terminals 10, 11. Secondary windings 15, 20 of transformers 14, 19 provide a voltage displaced 180 degrees from the anode voltage to cut off the valves in the rest position of the control. The way in which the varying A.C. voltage on one grid of valves 8, 17 alters their output is described with reference to their characteristic curves, Figs. 2, 3 (not shown). Fig. 5 shows a circuit in which the armature of motor 37 is energized from A.C. source 10, 11 with direct current flowing in one direction or the other through valves 8 or 6 according as light falling on photo-cell 22 rises or falls about a set amount. Changes in the photo-cell vary the voltage drop across grid leak resistor 28 derived from the potential divider 23, 24, 25 connected across D.C. terminals 26, 27 so that with change in one way the grid of valve 21 becomes more positive and the alternating voltage across transformer 32 increases to fine valve 8 while the increased voltage across resistor 33 decreases the grid potential of valve 29 so that the voltage from transformer 36 decreases and valve 16 remains cut off. With change in the other direction, the voltages from transformers 32, 36 fall and rise respectively and valves 8, 16 are cut off and fired respectively. Valves 8, 16 may be replaced by valves with a single grid, when the outputs from transformers 32, 36 are rectified. The alternating voltage then applied to the grids of valves 21, 29 will be displaced. from their anode voltage by 90 degrees.
