Abstract: A method for purifying metal M1 particles manufactured by an electrochemical reduction process, the method comprising the steps of introducing the metal M1 particles into a heat source (13) at a temperature substantially equal to or higher than the melting point of M1 so as to cause vaporisation of some or substantially all of the contaminating impurities present, removing the vaporised impurities from the vicinity of the particles, and cooling the purified metal M1 particles. The purified particles can be used directly in lower temperature powder metallurgy processes and have a fully dense spherical particle morphology, imparting good flowability. The purification process can also be incorporated as an integral stage of sheet or stock production processes based on particle feedstocks that have been produced by electrochemical reduction.

Abstract: A mass flowmeter for measuring velocity of a flowing fluid employs a thermal sensor (11). The sensor (11) generates heat when supplied with electrical power. A heat sink (25) is located in the fluid flow a selected distance normal to the line of flow of fluid from the sensor. Electrical power is supplied to the sensor (11) to cause a thermal flux to flow from the sensor (11) to the heat sink (25). The flowing fluid modulates this flux. A circuit (23) measures the temperature of the sensor and computes the velocity of the flowing fluid from that measurement.

Abstract: A method for assay for an unknown enzyme suspected to be present in a liquid includes signal amplification by use of a second enzyme and a blocked modulator for the second enzyme. Unknown enzyme in the liquid removes a blocking group from the blocked modulator. The resulting modulator activates or inhibits the second enzyme which catalyzes an indicator reaction in which a substrate is converted to a product. The presence or absence of the unknown enzyme in the liquid is indicated by a signal, such as a color change or a rate of color change, associated with the indicator reaction. The concentration of the enzyme in the sample may be determined by the measurement of the signal. The invention includes a kit of materials useful for performing the method of the invention.

Abstract: Apparatus for welding longitudinal seams in can bodies includes a lower electrode wheel 10 mounted on an arm 18 and an upper electrode wheel 12 mounted on an arm 20. Metal Blanks bent into a tubular form are supplied to the nip between wheels 10,12. The apparatus also includes a transducer 40 for detecting vertical displacement of wheel 12, a pair of pick-ups 46,48 for detecting the rotational positions of wheels 12,10, and a single processing circuit. In order to determine the profile of one of the wheels 10,12, the output of transducer 40 is divided into a set of traces, each of which corresponds to a single rotation of the wheel. The traces are then averaged to produce an averaged trace, which represents the profile of the wheel. In order to determine weld thickness, the profile of each wheel, in turn, is subtracted from the output of transducer 40 to produce a corrected output which provides a good indication of weld thickness.

Abstract: Method of heat treatment of a steel product leaving the rolling mill in which, during a first stage, the product is subjected to cooling with water to a surface temperature which is equal to or lower than the temperature of the onset of the martensite transformation (Ms point) of the steel, with a rate of cooling which is at least equal to the critical rate for quenching the steel; during a second stage the product is first of all subjected, by virtue of the heat released by the unquenched part of the product, to a reheating of the quenched surface layer to a surface temperature, known as the self-annealing temperature, of between 550 DEG C and 650 DEG C, and then to a secondary cooling to a surface temperature of less than 450 DEG C; the final cooling of the product to a temperature of less than 120 DEG C is then performed, for example with the aid of highly agitated water. During the stage which follows the self-annealing, the product may first of all advantageously be allowed to stay in air up to a temperature of approximately 550 DEG C, and then be cooled at high speed to a temperature substantially below 400 DEG C, and be reheated to a temperature of between 400 DEG C and 420 DEG C before being allowed to cool in air. <IMAGE>
