Title: A Device for Ultrasonic Inspection of the Quality of a Tubular Part
IPC: G01N29/26
Filed: 1979-02-05
Abstract: Immersed testing of a moving tubular part within a tank filled with an acoustic couplant fluid is performed by means of at least one stationary but positionally adjustable ultrasonic emitter-receiver tranducer 22a, 22b of annular design having a flat active face 26a, 26b directed towards a stationary ultrasonic mirror 18, 16. The mirror surrounds the tube and reflects the ultrasonic beam onto the tube wall at a constant angle of incidence. The active transducer face is divided into at least two separate active parts (Figs. 2, 3 not shown) which are excited cyclically and successively in time. The inspection device achieves high signal reproducibility in any angular location of flaws and a substantially enhanced signal-to-noise ratio. Inspection can be by transverse waves A2 or longitudinal waves A1. In the latter case a helical mirror 18 is associated with an effectively spiral transducer (Fig. 3). <IMAGE>

Title: Mineral preparation apparatus
IPC: G01N23/02
Filed: 1979-02-06
Abstract: This invention relates to an apparatus and method for controlling the operation of a coal preparation plant. The apparatus includes a sampling device (6,7) which takes a sample of the tailings from the plant. The sample is concentrated in a concentrator (e.g. cyclone separator (8)), which produces a concentrated sample having a solids content of about 30%, which is sensed by nucleonic sensor (10) which produces a signal proportional to the contaminant content of the tailings. The apparatus may also include a density meter (9) which produces a signal proportional to the density of the sample, which signal may be combined with the contaminant sensor signal to give a combined signal which is more accurately proportional to the contaminant content of the tailings than is the contaminant sensor signal alone. Either signal may be used to vary the action of a control device, which controls the operation of a part of the plant or operates an alarm. The present invention allows the continuous and automatic monitoring and control of the operation of a coal preparation plant. The invention is envisaged as of being in use in mineral preparation plant, and in particular in coal preparation plants. <IMAGE>

Title: Compensated input circuit for use with bipolar return to zero line signals
IPC: G11B20/14
Filed: 1979-03-22
Abstract: An input circuit for use with bipolar RT2 signals is transformer coupled for d.c. isolation and line impedance matching. Part of the input signal BL1 is tapped off, rectified and smoothed to provide a d.c. voltage which follows the amplitude changes of the input line signal. The d.c. voltage is used to vary the threshold of a level detector circuit which comprises a long tail triplet (TR1, TR2, TR3). Transistors TR1 and TR2 provide the signal output conditions whereas TR3 provides the variable threshold. The signals amplified by TR1 and TR2 are further amplified by transistors TR4 and TR5 which provide, at their collectors, the respective positive and negative mark binary output signals. <IMAGE>

Title: Alarm Apparatus
IPC: G08B25/04
Filed: 1979-08-14
Abstract: An alarm apparatus comprises a plurality of detector stations 2 connected in a ring circuit to a monitoring station 3. A fire smoke or intruder alarm detector 4 is associated with each detector station and a pulse generator 5 supplies a pulse to the stations 2 and 3. The detector stations transmit for a predetermined time a signal to the monitoring station 3 after a predetermined delay after receiving the pulse and the predetermined delay of each detector station is different so that if no detector is actuated a series of successive signals is transmitted to the monitoring station. The monitoring station actuates an alarm device 6 if any of the signals is missing and the alarm device reverses the polarity of the power supply to the detector stations to actuate an alarm indicator which is connected to the same power supply conductors via a diode which is reverse-biased when no detector 4 is actuated. <IMAGE>

Title: Inhalation device with retractible mouthpiece
IPC: A61M15/00
Filed: 1980-07-25
Abstract: An inhalation tube for an aerosol container comprises a tubular body, 1, adapted for detachable fitting to an aerosol container, 6. A delivery mouth-piece, 7, is fitted which is movable between retracted and extracted position. The extraction and retraction of the mouth-piece is brought about by means of a cap, 10, rotatably mounted on the tubular body, which has actuating means, 9, associated therewith. The cap and tubular body have openings of similar dimensions. Rotation of the cap to bring the openings into register causes the actuating means to move the mouth-piece to an extracted position, whilst rotation of the cap to bring the openings out of register causes the actuating means to move the mouth-piece in a retracted, closed-off position wholly with the tubular body. Such an arrangement enables simple functioning of the inhalation tube and ensures that hygienic conditions are provided insofar as the mouth-piece is closed-off when not in use. <IMAGE>
