Abstract: A process for separating and recovering paraffin sulphonic acids from mixtures with water and sulphuric acid is described, consisting of:
     bringing such a mixture into contact under extraction conditions with a saturated aliphatic or cycloaliphatic liquid hydrocarbon;   separating an aqueous liquid phase containing sulphuric acid from an organic liquid phase consisting of the extraction solvent containing the paraffin sulphonic acids; and   recovering the paraffin sulphonic acids from said organic liquid phase.   
     The process is particularly applicable to products obtained from processes involving the sulphoxidation of paraffins with sulphur dioxide and oxygen, catalyzed by U.V. radiation.

Abstract: An ultrasonic distributed temperature sensor comprises an elongate ultrasonic waveguide in the form of steel or nickel wire 0.16 cm in diameter and up to 10 metres long, which is strung around the area whose temperature is to be monitored, eg an aircraft engine. The wire is provided with discontinuities in the form of annuli welded on to it to form annular flanges, which serve to partially reflect ultrasonic pulses launched into one end of the wire. These flanges, known as "posi-notches", divide the waveguide, and thus the area to be monitored, into a number of zones, the size of each zone being determined by the spacing of the adjacent flanges defining it. In operation, the temporal spacing of each pair of successive partially reflected pulses is a measure of the average temperature of the zone defined by the flanges producing that pair of pulses. In order to mount the waveguide in the area to be monitored, it is held by locating devices which engage the radial surfaces of some of the flanges, so locating the waveguide longitudinally, and by annular clamping devices which lightly grip the wire without introducing undesired stresses. In one embodiment, the locating devices and the mounting devices are basically very similar, and comprise an annular member having a bore containing at least three axially extending resilient strips which make line contact with the waveguide to support it.

Abstract: The relationship between the level of a hormone, such as the immune-regulating cytokine IL-1, in the blood stream of an animal and application of sensory stimuli to the animal is determined by periodically taking discrete samples of the animal's blood while the stimuli are applied, measuring the levels of the hormone in the discrete samples, and correlating these levels with the application of the stimuli. Thereafter, the level of the hormone is controlled by applying to the subject those stimuli that have been found to produce a desired effect on the level of the hormone in the blood. Biofeedback training and relaxation techniques are used to increase the effectiveness of the method and apparatus.

Abstract: Disclosed is a dry etching method by which a polycide film (5) consisting of a refractory metal silicide layer (4) and a polysilicon layer (3) are stacked one upon the other may be etched with high anisotropy, low pollution, high selectivity and high speed without using flon gases. 
     According to the method of the present invention, an etching gas containing a fluorine base gas mixed at least with HBr is used for etching the polycide film for realizing anisotropic processing under sidewall protection by a reaction product of mainly the resist material and Br. 
     Overetching for uniform processing in the wafer plane is performed with the use approximately solely of the fluorine base gas or HBr for realizing a high speed and improving substrate selectivity. 
     The overetching step is preceded by oxygen plasma treatment for oxidizing the reaction product and intensifying side wall protective effects while improving anisotropy. 
     Finally, the changes in the emission spectrum intensity during the etching are monitored for determining the end point of etching of the refractory metal silicide layer to enable more accurate setting of the etching conditions.

Abstract: The horizontal synchronous signal and the vertical synchronous signal included in a composite synchronous signal which is output from one TV camera are separated from the composite synchronous signal. A plurality of TV cameras are controlled on the basis of the horizontal synchronous signal and the vertical synchronous signal so as to produce synchronized video signals from the plurality of TV cameras. These synchronized video signals are easy to compound. In the blanking period of the vertical synchronous signal, the rise period of the synchronous signal is 1/2 of the period of the vertical synchronous signal. Pulses are eliminated alternately in the blanking period by a half killer circuit including a counter and a decoder and having a simple structure, thereby generating a horizontal synchronous signal appropriate for driving the TV cameras. The counter composed of Johnson counters connected in multiple stages reduces the amount of current flowing to the counter, thereby eliminating the deleterious influence on the TV cameras.

Abstract: The bearing device can be installed as a fixed location bearing (12) or as a floating bearing (13). The only difference here is in each case the orientation of an annular inner part (3) of the housing relative to an outer part (2) of the housing. This inner part (3) has a convex and spherical inner side which corresponds in shape to a spherical outer surface of a ball bearing (1). In the case of the fixed location bearing (12), the inner part (3) of the housing is inserted in such a way that this part is fixed in an axially non-displaceable manner by an integrally formed flange. In the case of the floating bearing (13), the inner part (3) of the housing is inserted in a position rotated through 180 DEG , allowing the inner part (3) of the housing to be displaced axially in the outer part (2) of the housing. In both cases, the ball bearing (1) can adjust in the bearing housing (2, 3) with a swivelling motion about the bearing centre. Installation tolerances and flexures of a shaft (9) can thereby be compensated and wear of the bearing correspondingly reduced. <IMAGE>
