Title: Aircraft cabin air pressure regulator
IPC: B64D13/04
Filed: 1946-05-29
Abstract: 615,676. Automatic control systems for pressurized aircraft. BENDIX AVIATION CORPORATION. May 29, 1946, No. 16360. Convention date, July 23, 1945. [Class 38 (iv)] In an aircraft cabin air pressure control system, the operating datum is controlled over a portion of the range in accordance with the atmospheric pressure. As shown, a bellows 33 responsive only to atmospheric pressure controls the angular position of the shaft 25 and so the position of the end of a bellows 19 responsive to the cabin pressure and consequently the pressure at which the latter bellows controls contacts 15, 16. Springs 28, 45 tend to rotate the shaft 25 in a clockwise direction, in opposition to the action of the atmosphere and cabin pressures on the bellows 33 and 19 respectively. The cabin air pressure is controlled by adjustment of the orifice 3 by the sleeve valve 4 which is set by the reversible electric motor 7 via the rack and pinion 8, 9. The motor 7 rotates in a direction dependent upon the setting of arm 13 between the contacts 15, 16 by the bellows 19. With the atmospheric pressure high enough to cause the screw 36 and stop 37 to engage, by the compression of bellows 33, the control system is at first ineffective as shown by the line AB, but after a given fall of pressure, the bellows 19 functions to maintain the cabin pressure constant, as at BC. With the external pressure low enough to cause disengagement of 36, 37, the springs 28, 45 operate to effect a constant ratio between the cabin and atmospheric pressures over range CD, while at D, 47 and 48 engage and the spring 28 only operates. Specification 593,585, [Group XXIX], is referred to. The Specification as open to inspection under Sect. 91 states that the springs 28, 45 may be arranged, first, to render the cabin pressure constant during a further fall of atmospheric pressure after point D is reached, and secondly to reduce it at a constant rate as the atmospheric pressure continues to fall beyond a datum value. This subject-matter does not appear in the Specification as accepted.

Filed: 1973-04-05
Abstract: 1452607 Fuel elements UNITED KINGDOM ATOMIC ENERGY AUTHORITY 1 April 1974 [5 April 1973] 16434/73 Heading G6C A fuel element comprises a fuel can 1 having an internal fission gas plenum chamber 5 with a wall portion of the can bounding the chamber 5' being adapted to vent the chamber in a controlled manner when the can wall reaches a predetermined temperature. This temperature is one approaching that at which a reduction in the yield point of the can material occurs such that ballooning is imminent. In one embodiment Fig. 2 the can 1 contains VO 2  fuel pellets 2 separated by a spring 3 from an end cap 4 to form the chamber 5' in the can wall bounding which there is an insert 6 of a material which melts at the predetermined temperature to allow venting of the chamber 5'. In an alternative embodiment Fig. 3 (not shown), the insert is a double-headed rivet in a hole in the can wall, which rivet becomes loose at the predetermined temperature due to the difference between the thermal expansion coefficients of the rivet and the can wall material. Suitable materials are Zircalloy for the can 1 and gold-plated Al or Zr-Be alloy for the insert 6 of the first embodiment, and Zircaloy-2 for the can and Zircaloy-30 for the rivet of the second embodiment. In a third embodiment, Fig. 4, a stainless steel plug 11 is inserted as a loose fit at room temperature in a hole 10 in that part of the wall of the can 1 bounding the chamber 5'. As the can 1 warms up to operating temperature so the plug 11 expands to fill the clearance in the hole 10. The plug 11 is preferably sealed to the can 1 by a braze 12. A Zircaloy plug 14 is fitted into a central hole 13 in the plug 11, being a press fit at normal operating temperatures. At the predetermined temperature, the stainless steel plug 11 has expanded a greater amount than the Zircaloy plug 14 which becomes loose and is pushed out by the differential pressure across the wall of the can 1 so creating a relatively large leakage path.
