Abstract: An ultrasonic diagnostic apparatus for forming a sectional image of a subject by either a movable focusing system or a variable aperture system based upon echoes obtained by applying ultrasonic radiation onto the subject. The echoes from the subject are converted (100, 102) into signals depending upon their intensities, and different time delays are imparted thereto to form (110, 112) signals that correspond to different depths in the subject. Among the latter signals, those corresponding to particular depths are selectively combined (108, 113A, 113B. 114A, 114B, 116A, 116B, 118A, 118B, 120, 122A. 122B, 124), and thereby a sectional echo image of the subject is visually displayed (126, 128, 130). In changing the depth of aperture, the level of the combined signal (204) from the adder (120) is adjusted depending on the delay time defined by the delay circuits (116A, 1168) such that the average level of the combined signal (204) at the time of change will become substantially the same as that in the ordinary condition. Therefore, the change in sensitivity due to a change in the focal point or the aperture can be minimized, and a high azimuthal resolution is obtained.

Abstract: The current supply apparatus contains a mains transformer (2) which is connected on the primary side to the supply network and on the secondary side to loads via further switch elements (5, 6). The core of the mains transformer (2) can be split into two parts (7, 7') in a plane (a - a') lying between primary winding (3) and secondary winding (4). The part (7) of the core bearing the primary winding (3) can be moved on guide elements (8, 8') perpendicularly to the separation plane (a - a') for interrupting the inductive transmission. If the separating plane (a - a') lies in a wall (10) of an electronic device separating an explosion-proof region from a non-explosion-proof region, then the feeding of supply energy can be interrupted from outside without operating switches, plug connections or the like. <IMAGE>

Abstract: The present invention is related to a composition and methods for producing highly pure, high temperature superconducting materials having the general formula MBa₂Cu₃0₇-­x′ where M is yttrium or a rare earth element and x is from 0 to 0.5. The superconducting material is produced by first obtaining a solution of yttrium or rate earth element and copper. Next a solution of barium is obtained. The two solutions are heated and mixed together forming a precursor precipitate of the superconducing material. Subsequently, in one embodiment of the invention, the precipitate is recovered, calcined, sintered and slow cooled in oxygen or air. This produces a material having a desirable orthorhombic structure which is superconductive at high temperatures. 
     Because no organic solvents are used and no pH control other than the amount of barium in the solution is employed, it is possible to provide a highly pure superconducting material.

Abstract: A motorized power steering apparatus for a vehicle has a torque sensor (3) which generates an output voltage proportional to the steering torque exerted by the driver of the vehicle and a supply voltage. A motor controller 9 controls the output torque of a drive motor 7 which generates an auxiliary steering force corresponding to the output voltage of the torque sensor. The supply voltage for the torque sensor is decreased as the vehicle speed increases, so that the output torque of the motor for a given steering torque decreases as the vehicle speed increases.

Abstract: The system monitors at least one elementary fibre optic connection (F) conveying a useful signal with a transmission wavelength ( lambda T) between electro-optic transmitter (E) and receiver (R). An optical reflectometer (REF) periodically generates measuring pulses with a wavelength ( lambda M) differing from the transmission wavelength ( lambda T) in the optical fibre (F), through a wavelength duplexer (DU) preferably situated on the transmitter (E) side. The duplexer has a first access (AC1) connected to the transmitter (E), a second access (AC2) connected to the reflectometer (REF) and a common access (AC3) connected to the input end of the optical connection (F). A computer (CAL) connected up to the reflectometer (REF) localises an abnormal attenuation jump in the connection greater than a specified threshold by processing back-scattered signals detected by the reflectometer and transmitted from the common access (AC3) to the second access (AC2) in response to the measuring pulses. The processing of signals consists in calculating the difference of back-scattering functions, the integral of the difference, and the abscissa of the slope break point of the integral by successive dichotomies and linear regressions. The threshold, of the order of 0.002 dB, is less than the vertical resolution of the reflectometer, of the order of 0.01 dB. A single reflectometer and computer assembly can be used to monitor a fibre optic cable by virtue of the pairwise looping of the ends of the fibres by means of wavelength duplexers. <IMAGE>

Abstract: The method of supplying a treating agent to the exhaust gas stream in combustion processes provides for mixing a carrier medium with a treating agent, these media being brought before mixing to a pressure level necessary for atomization in a single-component nozzle. The ratio of the quantities of treating agent and carrier medium is infinitely adjustable and is adjusted as a function of the NOx gas concentration in the treated gas stream or as a function of the gas rate. The essential fact in this process is that a plurality of atomization nozzles are arranged in different planes and that the flame evolution in the firing space is monitored by flame detectors. When the flame front reaches the lowest nozzle plane, the feed of treating agent to these nozzles is shut off and the nozzles which are located above and in which there are as yet no flames, are controlled with respect to the throughput of treating agent as a function of the NOx gas concentration or of the exhaust gas rate. As soon as the flame front forms again in the region of the lowest nozzles, these atomization nozzles are fed again with treating agent. Even without treating agent, the lower atomization nozzles can be fed with carrier medium in order to cool the nozzles, if the carrier medium is water. <IMAGE>

Abstract: Silicon nitride sintered bodies are disclosed which contain rare earth element compounds and silicon carbide, and in which the intergranular phases between the silicon nitride particles are substantially crystallized. To make such sintered bodies, rare earth element oxides and a silicon carbide powder raw material are used as additives when preparing raw powders and the intergranular phases are crystallized during a temperature descending stage following a firing. The silicon carbide achieves effective densification of structure of the sintered body and crystallization of the intergranular phases, thereby making it possible to provide sintered bodies having intergranular phases with little glass phase uncrystallized and having excellent high-temperature strengths.

Abstract: A device for controlling 'U' tubing in the flow of a fluid such as cement in oil well casings comprises a body (16;41;83) which is inserted in the casing (10;81) towards its lower end. The body provides a passage (22,23;46,47;90,93) so that cement can pass through the body and out of the end of the casing before passing up round the exterior of the casing, displacing mud in front of it. A member (25;48;85) is mounted in the passage which normally does not impede the flow of cement through the passage. However, when the pressure differential at spaced points along the flow of cement increases beyond the predetermined level as a result of 'U' tubing, the member moves to restrict severely the area of the passage. This halts 'U' tubing. The member can move back to the full flow position once 'U' tubing has been controlled.
