Title: Reactor exhaust gas treatment plant - for extraction of hydrogen, oxygen and radionuclides
IPC: G21F9/02
Filed: 1972-12-20
Abstract: The dissolved gases in the reactor coolant are first extracted in a separator and then fed to a first reservoir tank before being passed through optional buffer tanks to allow radioactivity decay, to a catalytic reactor chamber for extraction of H2 and/or O2. The gases then pass to a condenser associated with a low temp. still to extract the radio nucleides. Finally the residual inert gases including N2 are passed to a final reservoir whence they may be recycled. Safety and rehability.

Title: Ultrasonic welding rig for plastic sections - to carrier tape produces notch by ribbed tool for section separation
IPC: B29C65/08
Filed: 1973-10-23
Abstract: Ultrasonic welding is applied to joina plastics shaped section to a carrier band (tape of a sliding clasp fastener) by feeding a rod of plastics matl. between the band and an ultrasonic vibrator head. The tool on the face on the latter has a protruding rib at the side of the matl. feed which produces a notch in the section. The section is parted off by applying a tensile stress through an offset motion or a pull. This provides a satisfactory and rapid parting of the shaped section from the bar stock; the danger of the bar stock end sticking to the tool is eliminated.

Title: Determn. of metals by atomic absorption spectrophotometry - using graphite tube coated with rhenium followed by tungsten
IPC: G01N33/20
Filed: 1974-03-04
Abstract: A hollow tubular body comprises a graphite substrate coated at least partially with a layer (I) of rhenium a few microns thick, followed by a layer (II) of tungsten between several tens and several hundreds of microns thick. Alternatively the substrate may be coated only with Re, several tens to several hundred microns thick. The layers are pref. obtd. by the decompsn. of ReF6 or WF6 in H2 at high temp. and low pressure. The coated tube is pref. used in appts. for atomic absorption spectrophotometry for the determn. of metals forming carbides which are stable at high temp., esp. Cr, Ca, Mo, V, W, Ti, Zr, Hf, Ta, Nb, where a soln. of the metal is carried by a gas into the tube, which is above 2000 degrees C so the metals are atomised. Atomic absorption spectrophotometry can now by rapidly, accurately and economically used for determn. of metals forming stable carbides which previously led to false results. By coating the graphite tube with rhenium followed by tungsten the carburisation of the outer layer of W by the graphite is precluded and accurate determn. of the above metals is possible.

Patent FR-2261410-A1 (FR)
Title: Pneumatically driven rotary vibration generating motor - is bolted to appliance being vibrated, through cylinder end plates
IPC: F01C1/344
Filed: 1975-02-19
Abstract: The motor has a hollow shaft carrying an annular piston which is caused to rotate by compressed air entering through slots in a blade in the shaft. The centrifugal force of the rotating piston is used to generate oscillator forces which are transmitted to the appliance to be vibrated. The force is transmitted from the rotating piston through the shaft to the end pieces of the cylinder casing which contain the shaft bearings. Securing studs through the end pieces hold the motor to the appliance being vibrated so that the forces are transmitted directly from the end pieces to the appliance. The forces are not taken through the housing which can thus be lighter and therefore cheaper.

Filed: 1975-11-20
Abstract: Process for the manufacture of N-(2-halogenoethyl)-N-(2-hydroxy-2-phenylethyl)amines, known intermediates in manufacture of the anthelmintic tetramisole. In one alternative, process comprises reacting N-(2-hydroxyethyl)-N-(2-hydroxy-2-phenylethyl)amine with a halogenating agent, e.g., thionyl chloride, to give N-(2-halogenoethyl)-N-(2-halogeno-2-phenylethyl)amine salt, and reacting latter compound with water to give said monohalogeno compound. In another alternative, the isomeric N-(2-hydroxyethyl)-N-(2-hydroxy-1-phenylethyl)amine is reacted with halogenating agent to give N-(2-halogenoethyl)-N-(2-halogeno-1-phenylethyl)amine derivative, and reaction of latter with water gives said monohalogeno derivative. In another alternative, a mixture of the two said dihydroxy compounds is used as starting material. Conversion of the two dihalogeno derivatives to the same monohalogeno derivative proceeds, apart from exceptional circumstance, via an aziridine derivative.
