Abstract: In order to sort diamond-bearing ore particles (2) conveyed on a wide belt (1), exciting radiation strikes the belt along an extended line. Diamonds are detected by passing the emitted radiation through a narrow band pass filter (9) sensing the Raman radiation with a photo-multiplier tube (14).  Only axial-parallel rays passing through the filter reach the photo-multiplier tube. An array of side-by-side converging lenses (6) can be used, the lenses being of rectangular shape as seen looking along the optical axis with their long axes at right angles to the line of radiation. The ore particles are in the plane of the foci of the lenses, so that radiation emitted by each particle is passed in parallel rays through the filter. In order to stop rays having an angle of incidence greater than the maximum permitted, to avoid identifying non-diamond material as diamond, a further converging lens (10) is used to focus the rays at the plane of a telecentric stop (11). The stop stops rays having too great an angle of incidence. The position of the   diamond can be detected for instance by a CCD array or by a time domain technique. The apparatus can be monitored by giving a signal when the radiation from tracer stones and holes on either side of the belt, differs from predetermined values.

Abstract: A magnetoresistive sensor that includes a thin film of nominally undoped monocrystalline indium arsenide. An indium arsenide film is described that appears to have a naturally occurring accumulation layer adjacent its outer surface. With film thicknesses below 5 micrometres, preferably below 3 micrometres, the presence of the accumulation layer has a very noticeable effect. A method for making the sensor is also described. The unexpected improvement provides a significant apparent increase in mobility and conductivity of the indium arsenide, and an actual increase in magnetic sensitivity and temperature insensitivity.

Abstract: A family of semiconductor diode lasers is made available whose emitted laser light beam intensity can be electrically modulated with low voltage, low current modulating control bias signals. By appropriate design of the diode laser devices in accordance with the invention and provision of means for adjusting the relative values of the applied modulating control bias signals, the improved diode lasers can be switched on and off electrically in addition to modulation of the emitted output laser light beam intensity. Further, the physical position of the emitted laser light beam spot along the laser facet readily can be moved by the same electrically operable control means so as to provide modulation, turn-on and turn-off and small lateral movement as well as scanning of the laser light beam in a single heterostructural diode laser device.

Abstract: A process with improved economic efficiency for the catalytic and/or thermal post-combustion of process waste air containing organic compounds in variable concentration by passing the process waste air through a post-combustion zone is characterised in that, above a minimum value of the flow volume through the post-combustion zone, this flow volume is controlled so that the temperature increase of the process waste air in the post-combustion zone remains below a preset maximum value and below 1300 K, and in that the feed air to the post- combustion zone is preheated in such a manner that the post-combustion zone waste air has a temperature within a predetermined range. An apparatus for carrying out this process has a device for measuring the temperature increase in the post-combustion chamber, a device which controls the device regulating the feed air in the post-combustion chamber depending on the temperature increase in the post-combustion chamber, and a heating device installed in the post-combustion chamber feed air pipe.

Abstract: A control circuit (16) mounted on a faucet (10) operates an ultrasonic transducer (20) that transmits ultrasound into a target region (22) below the outlet (24) of the faucet. The control circuit receives electrical signals from the transducer when the transducer receives echoes from objects within the target region. The control circuit times the echoes to determine the distance of the object causing the echoes, and, if the distance of the object changes between successive measurements, the control circuit operates a valve (12) having an actuator that requires power only to change state so that it keeps the valve open when no power is applied. The circuit is powered by a rechargeable battery (18) that is charged by the action of a gene­rator (31) that is driven by a turbine (34) powered by the flow of water through the faucet.

Abstract: The corrosion resistance inherent in stainless steel (1) is further improved by a cladding layer (3) provided on the surface thereof. The cladding layer (3) is formed of a coating material (2) which is applied onto the surface of the stainless steel (1) and, then, burnt to be fused by laser beams. The coating material (2) contains a larger amount of Cr than that of the stainless steel. The thus fused material and a fused portion of the stainless steel are mixed with each other to form the cladding layer of remarkable corrosion resistance due to a larger amount of Cr contained therein. The formation of the cladding layer (3) on the inner surface of a small diameter pipe (22) is enaoled by a coating film shaping device which has a jig (23) for shaping the applied material into a film of a uniform thickness and by a laser irradiation torch (101) which has an arrangement for emitting the laser means radially outward from the inside of the pipe.

Abstract: An ultrasonic air-in-line detection system for use detecting air bubbles in the fluid line (306) of a disposable cassette mounted on a main pump unit in which a self-test procedure (900) is periodically used to ensure that any faults in the ultrasonic air-in-line detector which so not fail safe are automatically detected. After a pumping cycle is completed, if the ultrasonic air-in-line detector indicates that there is liquid in the fluid line at the location of the ultrasonic sensor, the operating frequency of the transmitting ultrasonic transducer (866) is changed to a non-resonant frequency for the self-test procedure. If the ultrasonic air-in-line detector still produces a signal indicating that there is fluid in the line, this indicates that there is a failure in the ultrasonic detector and a fault is indicated and the system is shut down.
