Patent GB-812655-A (GB)
Abstract: 812,655. Cold cathode tubes. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 19, 1957 [June 22, 1956], No. 19303/57. Class 39(1). In a glow-discharge tube, in which an auxiliary anode is located near the main cathode and the main electrodes are parallel flat plates, the gas-filling consists of a pure rare gas at such a pressure that the product of this pressure and the distance between the main electrodes lies to the right of the minimum on the Paschen curve of the gas concerned but is smaller than the value at which oscillation occurs. The auxiliary anode is a flat element situated near a sharp projecting part of the main cathode, located laterally of the main discharge path, so as to render the break-down voltage lower than that corresponding to the minimum on the Paschen curve. With this arrangement there may be a high ratio between the ignition voltage of the main anode and that of the auxiliary anode. As shown, the molybdenum cathode 3 is provided with a thin molybdenum wire 5 closely spaced from the auxiliary anode 6. The auxiliary anode preferably consists of a material such as nickel, the work function of which is in excess of that of the cathode so that the break-down voltage from the main anode to the auxiliary anode exceeds that to the cathode. At the side of the main anode 4 is provided an auxiliary cathode 7 which may carry a very weak current to prevent ignition delays. In the example given the gas filling consists of pure neon at a pressure of 90 mms and the main-electrode spacing is 3 mms, the corresponding break-down voltage between the main electrodes being 340 volts.

Title: Combination microwave gas convection oven
IPC: H05B6/80
Filed: 1982-01-13
Abstract: The oven has a tubular burner 80 operating in an induced draught environment. Two counter rotating blowers 60 in a chamber 56 draw air from a combustion chamber 54 and force it into the oven cavity 12 through perforations 65. The slight negative pressure created in the combustion chamber 54 draws air in from the cavity 12 through perforations 62, thereby completing the convection recirculation. The negative pressure in the combustion chamber 54 also causes secondary combustion air to be drawn up along the sides of the burner 94 which is positioned just below an aperture 100 in the floor of the combustion chamber. The burner 94 has a plurality of top ports which provide low port loading and are preferably slots transverse to the length of the burner. The structure provides good flame characteristics with low noise of combustion. A magnetron 24 feeds microwave energy into the bottom of the oven cavity 12. <IMAGE>
