Title: Contact regulators
Inventor: BARRY THOMAS JOHN
IPC: G05B1/04
Filed: 1959-12-30
Abstract: 925,710. Automatic control. ETHER Ltd. Oct. 19, 1960 [Oct. 19, 1959], No. 44201/59. Class 38 (4). In a contact regulator, a settable pointer f is carried on an insulated member e joining the ends of flexible conducting bands a, b tensioned around pulleys h, i by a spring cl inked to the bands by insulated couplings d. A movable pointer m of an indicating or recording instrument carries contacts n, o engaging a band and a conductor p, respectively. Contacts q, u, engaging the bands, are connected to terminals r, t, respectively. The insulated member e carries a printed circuit comprising a resistor v having tapping fingers engageable with the contact n. In a control circuit for a furnace, wherein the indicating instrument is responsive to furnace temperature, a coil 3 of a relay controlling the fuel supply is connected in series with a transistor 4 across a direct current supply. When the movable pointer is in the position shown, the base bias of the transistor is derived from a potentiometer formed by a resistor 2 and the printed circuit resistor v, and the relay coil 3 is sufficiently energized to close switch 7 and move a switch-arm 7 to engage a contact 10, thus causing an increase in fuel supply to the furnace. Closing of the switch 7 applies a bias to the transistor, through resistors 5, 8, tending to reduce the collector current and simultaneously charges a capacitor 6. As the measured temperature increases the contact n traverses the resistance v so that the bias of the transistor is reduced until the current through the relay coil is reduced to a value at which the relay releases. The fuel supply is reduced by the switch-arm 9 engaging contact 11 and the switch 7 is opened. The capacitor 6 then discharges to alter the bias to the transistor and re-energize the relay coil 5. The system then cycles at an on-off ratio determined by the position of the movable pointer m relative to the settable pointer f so as to tend to maintain the temperature of the furnace constant. For use with a circular scale instrument the bands are arranged around the circumference of a single pulley.

Lubricating oil  enters the tank 10 which is divided by a wall 14, through a conduit 42 and is directed by a nozzle 40 into a vertical path within the deaerator 36 and against the walls thereof, the air leaves via a port 50 and pressure relief valve 80 (this  valve may be in the port 50) and the deaerated oil leaves via an outlet 46 and conduit 48. A jet pump 44 supplements the flow of oil entering the conduit 42, through a conduit 78, to ensure an adequate flow to the lubrication system via the outlet 46 when the aircraft is in a nosedown attitude. Air above the oil in the compartment 16 is vented through a port 60 and conduit 58. Oil from the hydraulic system enters compartment 18 through a conduit 84 and jet pump 86 and returns to the system via conduit 82. The oil is pumped from compartment 16 through the conduit 88 or discharged therethrough from the compartment 18 depending on the pressure due to the level of oil in the latter compartment. During level flight the oil level in compartment 18 is maintained by a float valve 96 which is in venting communication with compartment 16 via a passage 100 and a standpipe 114, a float 98 closing the valve 96 when the required oil level is reached. A gravity valve 106 prevents inadvertent oil exchange between the compartments 16, 18 during nose-up or inverted flight attitudes, while the standpipe 114 prevents any exchange during nose-down flight, though the latter may be dispensed with and a port 110 to which it is connected, be restricted in size. In the event of a leak in the hydraulic system a reserve of oil is available in the compartment 16, the free end of the conduit 88 being spaced from the tank bottom to ensure sufficient oil remains for the lubrication system.
