Abstract: A microwave plasma generator for producing an axisymmetric plasma, having a waveguide apparatus, means for introducing a microwave source into the waveguide apparatus, and means for generating a circular axisymmetric microwave field from the microwave source. There are means for tuning the field to match the impedance of a plasma load. Further included is a vacuum chamber for containing a gas to be ionized to form the plasma, means for introducing this gas into the vacuum chamber, and means for coupling the microwave field to the vacuum chamber to form the plasma.

Abstract: The electric incandescent lamp has a blown glass lamp vessel having a neck-shaped wall portion, a parabolically curved wall portion which extends substantially transversely and a wall portion curved in accordance with an arc of a circle which extends substantially in the axial direction. A filament is arranged in a plane through the foci of the wall portion and at least partly coincides therewith. The electric incandescent lamp has the advantage that, independent of its finish it has a lamp vessel of the same shape and the same mounting means for the filament. The manufacture of incandescent lamps of different types is thereby simplified considerably.

Abstract: A device for boosting power supply voltage is provided with a transformer having a secondary winding which generates an elevated voltage when the power supply current is supplied to the primary winding, whereby the voltage generated in the secondary winding is supplied to a load while voltages corresponding to the inverse electromotive force generated in the primary winding are supplied to another load.

Abstract: A short cathode ray tube (CRT) is formed wherein the axes of deflection in the X and Y directions are separated, and by bending the electron beam path in a region between the separated axes. The deflections and beam bending may be accomplished magnetically or electrostatically. The CRT may use a single electron gun or a multiple gun assembly.

Abstract: A thin-film EL display panel drive circuit capable of varying the drive voltage according to changes in the number of emitting picture elements.

Abstract: An electrodeless lighting system (10) is provided for converting electromagnetic energy whose spectrum is within the ultraviolet bandwidth into energy within the visible bandwidth of the electromagnetic spectrum through excitation of fluorescent composition coatings (20). The lighting system (10) provides for an excitation mechanism (12) which generates an enclosed magnetic field, an induced electrical field, and a radiating electrical field, where the induced electrical field is substantially parallel and in the same direction as the magnetic field. Both the magnetic and induced electrical fields are applied at substantially the same frequency for accelerating and directing electrons for collision with gas composition atoms contained within a closed contour gas housing (14) and in particular within a gas housing chamber (16). An electrostatic shield (26) substantially encompasses the excitation mechanism (12) is provided for containing the radiating electrical field within the lighting system (10).

Abstract: A lamp holder assembly for use with an incandescent fixture includes a base that provides a predetermined amount of rotational movement relative to the housing to allow proper orientation of the assembly with respect to the incandescent fixture. In one embodiment, a rib located on the internal surface of the base engages an arcuate-shaped projecting member at two spaced apart positions of movement. The spaced apart positions of movement define the amount of rotational movement which preferably is 180.degree..

Abstract: A stiffener is bonded to the bead of the flashlight bulb and extends along and between the pins. The stiffener includes indexing surfaces for use in laterally positioning the stiffener and flashlight bulb. An insert is bonded into a PR base so that the exposed end of the insert is a prescribed axial distance from an axial reference surface of the PR base. The insert includes a first set of indexing surfaces that center the insert in the PR base. The insert also includes a second set of indexing surfaces for receiving and centering the indexing surfaces of the stiffener with respect to the insert. The stiffener is inserted into the insert far enough that the bead of the flashlight bulb contacts the exposed end of the insert, thereby assuring that the filament is a prescribed distance from the axial reference surface of the PR base. A tight sliding fit between the stiffener and the insert assures that the stiffener is centered within the insert, which in turn is centered within the PR base.

Abstract: An electrical adapter assembly for enabling use of a fluorescent lamp in connection with an incandescent lighting fixture comprises a hollow and cylindrical housing, an Edison-type base extending from one end of the housing and a cover enclosing the end of the housing opposing the base. A toroidal ballast is located within the housing and is capable of receiving portions of the fluorescent lamp within hollow central portions of the ballast to enhance spacial efficiency. The base is either affixed to the housing, or alternatively, is rotatingly associated with the housing to provide a security feature.
