Abstract: CRYOGENIC TRANSISTOR WITH A SUPERCONDUCTING BASE AND A SEMICONDUCTOR-ISOLATED COLLECTOR               Abstract of the Disclosure This invention relates generally to cryogenic amplifying-switching devices and more specifically relates to a cryogenic transistor with a super-conducting base and a collector  isolated from the base by a semiconductor element.  Still  more specifically   the invention is directed to a three terminal, transistor-like device which incorporates three metal layers.  The first and second of the three layers are separated by an insulating tunnel barrier and the second and third layers are separated by a semiconductor layer of a thickness sufficient to inhibit tunnelling.  The semiconductor layer has a barrier height (low) which is sufficient to permit the passage of quasiparticles from the second layer while simultaneously inhibiting the passage of Cooper pairs.  The second layer is a superconductor while the first and third layers may be superconductors or normal metals.  The second and third layers are connected to the semiconductor layer by means of ohmic contacts.

Abstract: Abstract of the Disclosure An arrangement for providing heat to the working environment of a bucket attached to an aerial lift vehicle is disclosed.  A tubing arrangement is located at the bottom of the bucket and is receptive to heated hydraulic fluid.  The hydraulic fluid is commonly available at the bucket of serial lift vehicles for operation of the bucket and boom structures.  Since the hydraulic fluid may reach temperatures of 120°F, the circulation of the hydraulic fluid through the tubing structure in the bucket will radiate heat throughout the bucket.  In a preferred embodiment of the present invention, the tubing is encased in a mat which can be placed in the bottom of the bucket. Input and output couplers are used to attach the hydraulic hoses to the mat.  The control of hydraulic fluid flow through such an arrangement may be provided either at the bucket itself or in the vehicle.

Abstract: Abstract The object of the invention is to provide a continuous metal casting machine in which dimensional changes of the mold during the casting operation are measured and regulated to achieve a desired result in the cast metal.       The continuous casting machine includes a copper tubular or plate mold (22) into which molten metal (25) is poured for forming a strand (25b) of high melting point metal, such as steel.  A plurality of spray nozzles (29) are spaced around the mold for directing sprays (30) of coolant fluid against the mold.  In accordance with the invention, one or more measuring devices (32) are associated with the mold for measuring changes in dimension of the mold in a direction trans-verse to the longitudinal axis thereof, and controls (36) are connected with the coolant fluid to adjust the rate of heat extraction effected thereby to thus regulate the extent of dimensional change in the mold as molten metal is being cast therein.       The method of monitoring and adjusting the extent of dimensional change in a mold of a continuous casting machine as molten metal is being cast therein is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE      A method for location of a fault on a transmission line in a network for distribution and transmission of electric power uses a travelling wave model of the trans-mission line positioned in measuring stations (P, Q) at either end of the transmission line, to obtain the voltage distribution along the transmission line, seen from both station P and station Q.  A voltage .DELTA.UQp is generated as the difference between the voltage in station P, calculated in the travelling wave model in station Q, and the corresponding voltage one period/half period earlier.  A voltage .DELTA.UPp is generated as the difference between the voltage, calculated in the travelling wave model in station P, and the corresponding voltage one period/half period earlier.  The corresponding voltage differences .DELTA.UPp and .DELTA.UQq are calculated for station Q.  The voltage difference .DELTA.P is then generated as the difference between .DELTA.UQp and .DELTA.UPp and the corresponding voltage difference .DELTA.Q is generated as the difference between .DELTA.UPq and .DELTA.UQq.  The fault distance PF is then obtained as PF = .DELTA.P?PQ/(.DELTA.P+.DELTA.Q), where PQ is the distance between the stations.
