摘要： An electrical circuit breaker in which a pressurized gas such as SF6 operating on a closed gas circuit is utilized to extinguish the arc drawn between the switching contacts and perhaps also to actuate the contacts themselves includes an upstanding hollow insulator column at the top of which is supported a switch contact chamber and an adjacently located readiness tank containing the pressurized gas ready for delivery to the contact chamber as soon as a switching-out sequence is initiated. To assure rapid replenishment of the gas in the readiness tank so that a second switching-out operation can take place immediately, and at the same gas pressure as the first one should this be necessary, for example, due to the persistence of a short circuit on the line to which the breaker is connected, replenishment gas is stored in a cylinder at the lower end of the insulator column and this cylinder contains a piston which is driven in a direction to expell the gas stored in the cylinder and deliver it to the readiness tank through an interconnecting pipe line as soon as the gas pressure drops in the readiness tank as a result of delivery of the pressurized gas from the latter into the switch contact chamber. Thus the drop in gas pressure in the readiness tank resulting from the first disconnection of the switching contacts is compensated for and restored immediately by the re-pressurizing action resulting from the displacement of the piston.

摘要： Apparatus for measuring the temperature at the surface of an object by measurement of the infrared radiation emitted from its surface comprises a variably heated metallic body which serves as a compensating radiator, a reflective member mounted on a shaft within a cavity provided within the compensating radiator body for rotation, or alternatively oscillation, about an axis forming an oblique angle to the plane of the reflective member such that in one position of the reflective member only infrared radiation from the surface of the object is reflected by it into a radiation detector, while in another position of the reflective member only infrared radiation from a wall surface of the cavity within the compensating radiator is reflected by it into the radiation detector, thusly admitting infrared radiation from the object and compensating radiator in alternation to the radiation detector. The detector produces at its output an alternating current signal determined by any temperature differential existing between the object and compensating radiator, and the heat supply to the compensating radiator is varied in accordance with the signal in such sense as to reduce the signal to zero whereby the temperature of the compensating radiator then equals the temperature of the object.

摘要： An apparatus is disclosed for measuring the roughness of a surface with improved accuracy. The apparatus, several embodiments of which are disclosed, includes a device for illuminating a surface being studied and a photosensitive detector for determining the maximum intensity of light reflected on the surface. Apparatus is also provided for detemining two points at which the intensity of the reflected light has fallen to a selected fraction of its maximum intensity. The distance between these two points is then measured along the intersection of the plane of incidence of the illuminating beam with a plane perpendicular to the direction of specular reflection. This distance provides an accurate quantitative measure of the roughness of the surface being studied.

摘要： A turbine by-pass arrangement for use in thermal power plants serves to by-pass a portion of the steam delivered by the steam generator around the turbine and discharge it into the coupling sleeve located between the turbine outlet and the condenser inlet. The by-passed steam is divided into two parts, one of which is de-compressed as well as de-superheated while the other part is merely de-compressed. The two parts are admitted into the coupling sleeve in such manner that each constitutes a screen with respect to the other as regards protection for the turbine and condenser components of the installation.

摘要： Apparatus for measuring the temperature at the surface of thin elongated objects such as a metallic wire by measurement of the infrared radiation emitted from the surface of the object comprises a variably heated metallic compensating radiator provided with an opening through which the object passes and a rotatable chopper wheel interposed between the object surface and the compensating radiator. The side of the chopper wheel facing towards the compensating radiator is made radiation reflective and a radiation detector is positioned to receive in alternation the infrared radiation emitted from the surface of the object and which passes intermittently through the rotating chopper wheel and infrared radiation emitted by the compensating radiator and which is reflected intermittently into the detector from the reflective side of the chopper wheel. The detector produces at its output an alternating current signal determined by any temperature differential existing between the object and compensating radiator, and the heat supply to the compensating radiator is varied in accordance with the signal in such sense as to reduce the signal to zero whereby the temperature of the compensating radiator then equals the temperature of the object.

摘要： A steam power plant providing steam to drive a steam turbine coupled to an electrical generator includes a pressure-fired boiler the fuel flow rate of which is controlled by a livesteam regulator and a pressure-charging set consisting of turbocompressor for providing combustion air and which is driven by a gas turbine powered by the exhaust gas from the boiler and a starter motor, all on the same shaft. The speed of the pressurecharging set is regulated by varying the throughput of the gas turbine and/or the temperature of the gas turbine inlet in such manner that it neither produces surplus power nor requires power from the outside in accordance with variations in the steam power demand from the boiler as the load on the steam turbine changes. The starter motor for the pressure charging set is disconnected after starting and, at full load on the plant, the charging pressure for the combustion air is at least 9 bar, and the exhaust gas at the gas turbine outlet is no higher than 165*.

摘要： A method for producing electrical superconductors consisting of a great number parallel spaced thin filaments of a superconductive material in which diffusion is effected in parallel spaced zones between two adjoining metallic layers, one being vanadium and the other a copper-gallium alloy by utilization of a foreign substance between the layers establishing similar parallel spaced zones in which diffusion of gallium into the vanadium is either prevented or the superconductive properties of the inter-metallic compound formed by the diffusion is considerably reduced. The layered material with the foreign substance therebetween is formed into rods the axis of which corresponds to the direction of the parallel spaced zones; these rods are then embedded in a cylinder of a highly electrical conductive matrix material such as copper or aluminum, after which the matrix cylinder is subjected to a drawing operation to effect a reduction in its cross section and hence also the cross sections of the rods embedded therein, and then heat-treated to effect the desired diffusion of gallium from the copper-gallium layers to the adjacent vanadium layers along the parallel spaced zones between zones in which diffusion has been prevented or the superconductive properties of the inter-metallic compound formed at such zones have been reduced by the presence of the foreign substance.
