Patent GB-2237940-A (GB)
Title: Power controller for electric hotplate
Inventor: BUTTERY MICHAEL HARCOURT
IPC: H05B3/74
Filed: 1989-09-14
Abstract: In a LOW range of operation a heater element L1 is energised via an adjustable energy regulator and an element L2 is not energised, whereas in a HIGH range element L1 is energised continuously and element L2 is energised via the regulator. Elements L1, L2 may be of thick film material deposited on the underside of a ceramic hot plate, the resistance of L1 being twice that of L2. The control arrangement reduces inrush current problems associated with the high temperature coefficient of resistivity of such elements. A thermal relay may be provided to prevent energisation of element L2 before the hotplate has been warmed by element L1. The energy regulator may have a shaft carrying cams to operate switches S1 to S4 and a regulator adjustment cam, the cams being shaped so that the regulator progresses to full power energisation of element L1 over the first 180 DEG  of rotation, then switches element L1 to full power and connects element L2 to the regulator whereby further rotation to 270 DEG  increases energisation of element L2 from zero to full power. A stop on the cam shaft may prevent it being turned directly from OFF to the HIGH range. <IMAGE>

Abstract: A method of and apparatus for reducing the iodine content in a nitric acid nuclear fuel solution. In a reprocessing plant for burned off fuel elements from nuclear reactors, iodine expressed from substances contained in the fuel elements during a dissolution process is trapped in filters in a waste gas system. In order to reduce the residual iodine content of a nuclear fuel solution formed during the dissolution process, the nuclear fuel solution is first heated and blended with inactive iodine compounds, air and/or oxygen being supplied at the same time. Then, the nuclear fuel solution is heated and the vapour flow created thereby is passed through the nuclear fuel solution, nitrogen oxides being supplied at the same time.

Title: Vent valve for hot air balloon
Inventor: CAMERON DONALD ALLAN
IPC: B64B1/62
Filed: 1991-10-28
Abstract: A venting valve in a hot air balloon comprises a valve member (4) of parachute form located by constraining lines (6A) for closing an outlet hole (2) in the balloon envelope (1) and movable away from the hole (2), constrained by the lines (6A), to permit outflow of air from the interior of the envelope (1). A releasable locking mechanism (10) secures the valve member (4) to the envelope (1) to limit valve-opening movement of the valve member (4), the valve member (4) being freed for further valve opening movement upon release of the locking mechanism (10). In this venting valve, with the valve member (4) secured to the envelope (1) by the locking mechanism (10) the valve member (4) is prevented from moving clear of the effect of the outflowing air and hence from open condition is urged by this air to close again. The lines (6A) are sufficiently long to permit opening movement of the valve member (4) to a position clear of the effect of the outflowing air, allowing increased outflow of air, but such movement is only obtainable by release of the locking mechanism (10).   <IMAGE>
