Abstract:
A window of a transparent material suitable for closing an opening in a wall of a sealed container, which window has two conical portions whose bases face each other. An elastic seal is interposed between each of the conical surfaces and the wall of the opening.
Abstract:
A process for preparing oriented semiconductor monocrystalline rods with a specific resistance which drops towards the center of the rod. The process utilizes rapid non-crucible moving zone melting of a preformed vertically positioned semiconductor rod using an inductive heating device which annularly surrounds the rod.
Abstract:
A housing has an interior provided with two axially spaced and aligned openings, and is connectable in sealing relationship with a wall of the pressure vessel, so that one of the openings is in registry with a viewing port provided in this wall. A spherical, cylindrical or conical body having a bore is sealingly accommodated in the interior of the housing and can be turned to and from a position in which its bore registers with the openings and, hence, with the port. Sight glasses, lenses or the like are sealingly mounted in the bore and permit viewing of the interior of the pressure vessel when the body is in the position in which the bore registers with the openings.
Abstract:
A sight glass apparatus for viewing the interior of a pressurised vessel, chamber or a pipe conveying fluid under pressure is described. The sight glass apparatus comprises a sight glass assembly mounted over an opening into the vessel, chamber or pipe, the sight glass assembly comprising a sight glass adjacent the opening which provides a window to the inside of the vessel, chamber or pipe, and a containment vessel mounted behind and/or around the sight glass assembly for containing fluid exiting the opening in the pipe in the event that the sight glass assembly fails. In this way, even if the sight glass assembly fails, the pressurised fluid within the pressurised vessel, chamber or pipe is safely contained. In addition, a secondary sight glass can be provided behind the first, with a liquid or gel, or minimal gap, between the primary and secondary glasses to reduce the likelihood of a failure in the first sight glass triggering failure of the second sight glass, and/or a valve can be provided to automatically isolate the pressure system upon a sight glass failure.
Abstract:
The invention relates to a flange (4) for a CVD reactor (1) to which a camera, particularly a thermal imaging camera (10), has been attached by means of a fastening device (5), wherein the camera may be oriented such that at least one of the silicon rods (15) located in the CVD reactor (1) is captured. The invention further relates to a use of a camera, particularly a thermal imaging camera (10), for determining the diameter D of silicon rods (15) during the deposition process of pure silicon when conducting a CVD method. In addition, the invention relates to a CVD method for producing silicon rods (15) wherein the fluid volume of the process gas supplied is a function of the diameter D of the silicon rods (15).
Abstract:
According to the invention, a device which has an atomizing container (1) is provided for generating an aerosol comprised of a gaseous constituent, especially of air such as sterile air, and of a liquid constituent, especially of a sterilant such as peroxide. The liquid constituent is continuously atomized in said atomizing container (1), and is mixed into a gas stream passing into the atomizing container (1). To this end, an atomizing nozzle (8) for the liquid constituent of the aerosol is centrally arranged in the lower area of the atomizing container (1), and means (2; 23) for forming an upward-oriented directional gas stream are arranged upstream from the atomizing nozzle (8). Said gas stream flows around the atomizing nozzle (8) in a coaxial manner.
Abstract:
PURPOSE: A device for observing the inside of a high pressure reactor is provided which is applied to the high pressure reactor requiring reaction conditions of high temperature and pressure to observe physical phenomena during reaction that are generated in the reactor with the naked eye. CONSTITUTION: The device for observing the inside of a high pressure reactor comprises an observation means(40) that is coupled to a certain position on the outer circumferential surface of the reactor(20) or an opening part at one side of the reactor so that the observation means is connected to the inside of the reactor; and a beam irradiation means(50) which is coupled to a certain position on the outer circumferential surface of the reactor corresponding to a position that is spaced apart from an installation position of the observation means in a certain angle, or an opening part at the opposite side to the reactor so that the beam irradiation means(50) is connected to the inside of the reactor, and in which a separate light source is irradiated from the outside to the inside of the reactor, wherein the observation means(40) comprises a tubular member, a cover(42), a transparent member(43), a transparent member holder(44), and a sealing member(45).
