Described is a high intensity discharge lamp including a lamp bulb envelope, first and second electrodes, a seal and a fill situated within the lamp bulb envelope. The lamp bulb envelope is composed of single crystal sapphire tubing. The lamp bulb envelope includes end portions and a central portion, the central portion having a greater diameter than the end portions. The end portions may be a cylindrical tube shape and the central portion is a smooth three-dimensional shape. The first and second electrodes extend through opposite ends of the lamp bulb envelope so that at least a portion of each of the electrodes is situated within the lamp bulb envelope. The seal seals each of the first and second electrodes to an inside wall of the corresponding end of the lamp bulb envelope. A voltage is applied to the first and second electrodes to generate an arc plasma therebetween.

An invention for supplying power to a well. In one embodiment power heats a tubing from adjacent the surface to a selected level to prevent the formation of solids. The tubing is heated by passing an electric current therethrough. In one form the tubing is insulated from the wellhead and the casing down to a selected level where an electrical connection is made between the tubing and casing. Current is applied to the tubing at a point below an insulating tubing collar. In another form an insulated conduit is run into the well to a selected depth and connected to the tubing. Electrical power is connected to the tubing and to the insulated conduit.In another form a sucker rod is electrically insulated from the tubing down to a selected depth. The sucker rod includes a non-conducting section such as a fiberglas sucker rod. A conduit is run through the fiberglas rod and connected to the steel sucker rod therebelow.Also disclosed is a system for preventing formation of solids in a petroleum well by suspending a loop of wire in a well and passing a controlled amount of power along said loop of wire to heat the wire in which the loop of wire has sections of different resistance to apply different amounts of heat at different depths of the well. Further, there is disclosed an electromagnet for use as a contact between a wire and a well tubing and/or as an anchor.

A method and apparatus for curing three dimensional objects such as cylindrical two piece cans with ultraviolet light without having to rotate the cans, at conventional can line speeds and using a minimum number of lamp units. In a first embodiment, the cans are moved, without rotation, between at least a pair of ultraviolet lamp units so that the closest surfaces to the lamp units are substantially within the focal planes thereof. The lamp units are parallel to the direction of can movement or are rotated from that direction by a small angle with the lamp units of each pair being rotated by the same angle but in opposite senses. In a further embodiment, each lamp unit, instead of being faced by another lamp unit, is faced by a reflector to increase the cure speed attainable with the same number of lamp units.

An ultraviolet flux multiplying air sterilization chamber comprises inner surfaces having a diffuse reflective behavior. The sterilization chamber includes an inlet aperture and an outlet aperture for air to flow through said chamber and a light source emitting an ultraviolet light. Due to the reflectivity of the inner surfaces of the chamber, a flux of the ultraviolet light is multiplied by reflecting multiple times from the inner surfaces of the chamber. The inlet and outlet apertures are advantageously configured to reduce the amount of light that escapes from the chamber and increase the amount of photons available in the chamber. In an exemplary embodiment, perforated end panels having diffuse, reflective interior surfaces may be provided over at least a portion of the inlet and outlet apertures.

A high intensity discharge lamp, especially for optical projection systems, in one embodiment uses an anode electrode, a cathode electrode and a cylindrical envelope of single crystal (SC) sapphire. The fill may contain hydrogen, chlorine, sodium, scandium, sulfur and selenium and is under pressure exceeding 20 atmospheres. The lamp produces a continuous non-flash arc and generates a correlated color temperature between 6500 and 7000 degrees Kelvin and an efficacy exceeding 60 lumens/watt.
摘要:
A high intensity discharge lamp constructed with a tubular envelope composed of single crystal sapphire in which a continuous non-flash arc is created across multiple electrodes to generate a radiation emitting plasma. The lamp may operate at higher temperatures and pressures than conventional high intensity discharge lamps to produce greater luminance at any given power input. The lamp fill may be chosen from a wide range of gases and additives to produce the desired light spectra in the range from ultraviolet through near infra-red. The effective life of the lamp may be significantly extended. The lamp may be utilized particular benefits in image projection where a small powerful light source is required to optically match increasingly smaller image generation devices. In particular, the lamp may maintain a pre-selected correlated color temperature from 4,000 to 9,000° K over the life of the lamp. Alternatively, the lamp may be operated without electrodes utilizing microwave or radio frequency radiation as a power source.
摘要:
A method for establishing a region of a high density, high energy plasma at an altitude of at least about 1500 kilometers above the earth's surface. Circularly polarized electromagnetic radiation is transmitted at a first frequency substantially parallel to an earth's magnetic field line to excite electron cyclotron resonance heating in normally occurring plasma at an altitude of at least about 250 kilometers to generate a mirror force which lifts said plasma to said altitude of at least about 1500 kilometers. Heating is continued at a second frequency to expand the plasma to the apex of said field line whereupon at least some of the plasma is trapped and oscillates between mirror points on said lines. The plasma will be contained within adjacent field lines and will drift to form a shell of relativistic particles around a portion of the earth.

摘要:
A method and apparatus for altering at least one selected region which normally exists above the earth's surface. The region is excited by electron cyclotron resonance heating to thereby increase its charged particle density. In one embodiment, circularly polarized electromagnetic radiation is transmitted upward in a direction substantially parallel to and along a field line which extends through the region of plasma to be altered. The radiation is transmitted at a frequency which excites electron cyclotron resonance to heat and accelerate the charged particles. This increase in energy can cause ionization of neutral particles which are then absorbed as part of the region thereby increasing the charged particle density of the region.
