Abstract: An electrodeless lamp which couples strong microwave fields to a very small bulb of diameter about 1/2' or smaller. The lamp is operated in a mode which is independent of the height of the cavity and which provides electric field lines parallel to such height. The height of the cavity is substantially reduced as compared with prior lamps to provide strong coupling of the electric field to the bulb.

Abstract: An electrodeless lamp which couples to a small bulb and obtains a relatively high light output therefrom. A cavity which comprises a compound resonant structure including vestibule and reflector portions is provided. The combination of vestibule and reflector results in a condition of resonance throughout the cavity, whereby strong fields are coupled to the small bulb and a reflector is provided for directing and enhancing light output.

Abstract: A bipolar digitizer (A/D converter) is disclosed which uses a single comparator circuit for initially determining the polarity of a sampled input signal and for thereafter comparing the absolute magnitude of the signal to an applied ramp voltage. The time required for the ramp voltage to exceed the magnitude of the sampled input signal is converted into a digital waveform representative of the magnitude of the sampled input signal. Resistive means are selectively connected in shunt with a signal storage capacitor to achieve bipolar signal compression and increased dynamic range.

Abstract: A microwave oven having a directional rotating antenna axially supported on an axis of one wall of a microwave oven cavity of the microwave oven which provides circularly symmetric uniform energy distribution of microwave energy within the microwave oven cavity and consistent heating of a product in the microwave oven cavity. The directional rotating antenna includes a two-by-two array of antenna elements where each element is an end driven half-wavelength resonating antenna element supported by a length of conductor perpendicular to the wall of the microwave oven cavity. A parallel plate transmission line connects to each of the supports, four of which join at a junction which connects to a cylindrical probe antenna. The probe antenna is excited by microwave frequency currents of a waveguide adjacent to the wall of the microwave oven cavity. The directional antenna is rotated by a moving stream of air circulated through the microwave oven cavity. A dome having a flattened conical shape extending outwardly in the wall of the microwave oven cavity provides a nearly circular recess partially surrounding the directional rotating antenna and provides uniform energy distribution in the product being heated. The dome returns microwave energy reflected from the product towards a circular area in the middle area of the microwave oven cavity. A transition section extends between the top of the dome and the one wall of the microwave oven cavity. The waveguide including three sides affixes to the outside wall of the dome, the transition section, and an extension of the wall extending beyond the microwave oven cavity which supports the microwave power source, all of which comprise the fourth wall of the waveguide. The microwave oven provides a consistent cooking pattern, especially for sensitive foods by utilizing high power of the microwave power source.

Abstract: An electrodeless microwave discharge lamp includes a source of microwave energy, a microwave cavity, a structure configured to transmit the microwave energy from the source to the microwave cavity, a bulb disposed within the microwave cavity, the bulb including a discharge forming fill which emits light when excited by the microwave energy, and a reflector disposed within the microwave cavity, wherein the reflector defines a reflective cavity which encompasses the bulb within its volume and has an inside surface area which is sufficiently less than an inside surface area of the microwave cavity. A portion of the reflector may define a light emitting aperture which extends from a position closely spaced to the bulb to a light transmissive end of the microwave cavity. Preferably, at least a portion of the reflector is spaced from a wall of the microwave cavity. The lamp may be substantially sealed from environmental contamination. The cavity may include a dielectric material is a sufficient amount to require a reduction in the size of the cavity to support the desired resonant mode.

Abstract: An electrodeless lamp includes a stationary bulb (10) containing a fill for producing a discharge, the fill has a primary radiating material which ordinarily produces an unstable discharge in the absence of bulb rotation. The fill further includes an alkali metal in an amount sufficient to stabilize the discharge without bulb rotation. The alkali metal may be, for example, cesium bromide. Preferably, the fill is excited by a non-stationary electric field (E, E1) such as, for example, a circular polarized electric field.

Abstract: Method and apparatus for measuring gases dissolved in molten metal. Also disclosed are method and apparatus for dissolving gases in molten metal and a method of forming a gas permeable but molten metal impervious ceramic tube. A ceramic member is leached by an invention process so as to be selectively gas permeable. The member is inserted into molten metal to submerge the permeable portion. Then a vacuum is applied to the member and dissolved gases are measured by the change in pressure caused by gases entering from the molten metal. In another embodiment gas is applied to the submerged member to cause it to dissolve in the molten metal.
