Abstract: Method of and apparatus for stabilizing a plasma stream by the use of two different stabilization liquids. The plasma arc is stabilized in the discharge chamber by a whirl of a first stabilization liquid containing at least one element chosen from the group consisting of carbon and nitrogen, and the plasma arc is stabilized in the stabilization channel by a second stabilization liquid differing in its boiling point from the first stabilization liquid. Between the discharge chamber of the burner and the stabilization channel there is provided a transition space from which there lead outlets for the stabilization liquids. In the transition space there may be place an orifice plate dividing said space into two sub-spaces. From the stabilization channel upstream of the front nozzle of the burner there may be provided an outlet for the second stabilization liquid, which is disposed in the stabilization channel.

Abstract: The present invention relates to a method of producing self-supporting constructional elements by plasma-spraying onto a removable core.Recently, there is in widespread use the method of producing constructional elements, especially of heat-resistant elements of rotary shape, by plasma-spraying of ceramic oxides onto a removable core. Existing problems in the art are caused by the slow removal of an intermediate layer, which separates the deposited constructional element material from the core, in suitable solvents, and the necessary neutralization of the produced constructional element.These disadvantages are overcome by the method of the present invention characterized in that a core is preheated to a temperature in the range of from about 200.degree. C. to about 650.degree. C., a metallic or non-metallic intermediate layer having a thickness of about 0.1 to about 2 millimeters is deposited on the core by plasma-spraying.

Abstract: A soft contact lens is rested freely on a planar or convex (preferably spherical) surface immersed in a liquid. The liquid enclosed between the inner surface of lens and the planar or convex surface is sucked off and the volume of sucked off liquid is measured. A vessel with immersion liquid, having a plane or convex surface of its bottom is provided with a hole, which is connected with a measuring capillary tube through a broadened inlet chamber containing a mercury drop. The measuring capillary tube is furnished with a scale corresponding to its volume and is connected, at the outlet, with a drain or pressure reservoir through a broadened outlet chamber and a unit for pressure variation. The volume sucked off is determined by the shift in the mercury drop.
