Abstract: In the location of an earth fault on a sheath of an underground cable, pulses of direct current are applied to the sheath at one location on the cable. A search is made for the magnetic field due to a fault current to earth flowing in the sheath which is produced by the applied d.c. pulses using a portable magnetometer, with a visual indicator, and the visual indications on the magnetometer are correlated with the periods of application of the pulses to the sheath. Preferably, the pulses are correlated with the magnetometer indications by simultaneously transmitting signals indicative of the periods of current application and using, with the portable magnetometer, a portable receiver arranged to receive the transmitted signals so that the magnetometer indications by simultaneously transmitting signals indicative of the periods of current application and using, with the portable magnetometer, a portable receiver arranged to receive the transmitted signals so that the magnetometer indications can be correlated with the received signals.

Abstract: An electronic balance having highly improved accuracy of the measurement obtained by reducing the errors due to the scatter of data, which is an inevitable problem of the prior art in which the measurements have been made by calculating the simple average value of the sampled data during a predetermined period of time to avoid the interfering influences due to vibrations of the object being measured as such or caused by installing locations or windiness. In the electronic balance of this invention, the values of data sampled during a predetermined period of time are stored and at the same time the latest sampled values is compared in order with the previously stored values. When the value of difference obtained by the comparison is within a predetermined acceptable allowance, calculations are made for all the stored values to derive an average value. If the difference is beyond the allowance, the stored data are erased and the operations of sampling and comparison are repeated until the scatter of all the sampled values may come within the limit allowed. Since the electronic balance of this invention is capable of measurement with high accuracy even under the vibrative cirumstances, it may be effectively used for body-weight measurement of laboratory animals or various kinds of control system in factories, and further is applicable to measurement systems which are equipped on moving carrier means such as cars, ships and the like.

Abstract: The underlying technical problem is the production of squirrel cages for the rotors of large electrical machines, in particular producing the connection between the short-circuit rods arranged in the rotor lamination stack and the short-circuit rings terminating the squirrel cage on both end faces of the rotor. In the past, the rotors were produced by pressing copper profiles into slots of the rotor lamination stack provided for this purpose and subsequently brazing the short-circuit rods projecting over the rotor lamination stack to prefabricated short-circuit rings. Copper and copper alloys were preferably used as the material. This known method, and the materials used, resulted in considerable production costs. In order to avoid these difficulties and disadvantages, in the method according to the invention, the ends of the short-circuit rods are immersed centrally in an annular fluid metal mass. The temperature of the fluid metal mass is regulated such that the ends of the short-circuit rods are etched and such that a short-circuit ring is formed when the fluid metal mass solidifies which connects the ends of the rods to one another. Aluminium or an aluminium alloy are used as the material for the cage and the fluid metal mass (Figure 3). <IMAGE>

Abstract: In an arrangement for protection against overvoltage for electrical equipment, an overvoltage suppressor (1,11,21,31) is combined with an element of a shape-memorising alloy (7,17,24,25,34,35) which has the property, after cold deformation, of returning to its original shape once a specific, critical temperature has been exceeded and of maintaining this memorised shape even after subsequent cooling, at least within a certain temperature range. The arrangement is implemented such that the shape memorising alloy creates a short-circuit of the electrodes of the overvoltage suppressor when the critical temperature is exceeded and thus represents additional temperature protection. The resetting can be implemented either mechanically, manually, or in the case of shape-memorising alloys which operate on the hysteresis principle, by re-cooling. The arrangement is reversible, operates with a minimum of contacts and parts subject to wear, and is reliable over lengthy time periods.   <IMAGE>

Abstract: A method and apparatus is disclosed for use of a linear frequency chirp in a transmitter/receiver (14/16) having a correlator to synthesize a narrow beamwidth pattern from otherwise broadbeam transducers when there is relative velocity between the transmitter/receiver (14/16) and the target. The chirp is so produced in a generator (20) in bandwidth, B, and time, T, as to produce a time-bandwidth product, TB, that is increased for a narrower angle. A replica of the chirp produced in a generator (26) is time delayed and Doppler shifted for use as a reference in receiver (16) for correlation of received chirps from targets. This reference is Doppler shifted to select targets preferentially, thereby to not only synthesize a narrow beam but also aim the beam in azimuth and elevation.

Abstract: The invention is a process for the manufacture of substantially pore-free shaped articles from polycrystalline material, such as tungsten carbide, silicon nitride, titanium boride or silicon carbide, in which encased articles preformed from pulverulent materials and having open pores are isostatically hot-pressed in a vacuum-sealed casing of vitreous or ceramic-like material in a high-pressure autoclave using an inert gas as pressure-transfer medium. Before the application of the casing material, a first layer comprising material that can be decomposed or melted, such as an organic wax or a resin-like product, or of a compressible heat-resistant material such as inorganic fibers or felts, is applied to the preformed articles. Then, the encased articles are thermally treated until the glass or ceramic layer is fused or sintered gas-tight. The articles pretreated in this manner are then isostatically hot-pressed.
