Title: Determining the concentration of sulphur in coal
IPC: G01N23/223
Filed: 1975-03-14
Abstract: 1494549 Determining sulphur in coal COAL INDUSTRY (PATENTS) Ltd 17 Feb 1976 [14 March 1975] 10713/75 Heading G1A The concentration of sulphur in coal is determined by bombarding the coal with x-rays, measuring the intensities of the fluorescent x-ray radiations due to iron and sulphur and combining the measures mathematically to produce a measurement of sulphur concentration. Alternatively, for the type of coal in which the concentrations of non-pyritic iron, organic sulphur and sulphur present as sulphate are substantially constant, the sulphur concentrations can be determined from the fluorescent x-ray radiations due to iron alone. The x-ray source may be on x-ray tube, a "Bremsstrahlung" source or one or more radio isotopes. Two radio isotopes may be used, e.g. Fe 55  to excite the sulphur and Pu 238  to excite the iron.  The detectors may be single-semi-conductors preferably lithium-drifted silicon. The coal is preferably ground to a diameter of less than 0.5mm or less than 1mm for low ash coal. For coal where only iron fluorescence is measured the coal diameter may be 25mm but is preferably less than 5mm. As shown, ground coal on conveyer 3 moves past isotope sources 1 and 4, (1 exciting sulphur and 4 exciting iron), the fluorescent and backscattered radiations being detected in proportional counters 7, 7'. The detector outputs are amplified at 8, 8' and the sulphur and iron fluorescent radiations are selected by pulse amplitude selectors 9, 10. The resulting signals are mathematically combined at 13 and fed to indicator 15 or converted at 19, 20 to digital signals which are used to direct the coal to bins appropriate to its sulphur content.

Abstract: 1275039 Oscillators; frequency modulation TELEFONAKTIEBOLAGET L M ERICSSON 22 April 1971 [2 June 1970] 10838/71 Headings H3R and H3T A variable frequency oscillator comprises a frequency determining part that comprises two points between which there are coupled two branches in parallel, one branch comprising a capacitance C2, Fig. 1, and the other branch comprising, in series with a resistance element R3 with variable resistance that can be varied to change the frequency of the oscillator, two branches in parallel with each other of which one comprises a resistance R2 and the other a resistance R1 in series with a capacitance C1. In use, a current generator is connected across the two points and a control voltage V u  is derived across the series-connected resistors R1, R3. In an embodiment, the current generator comprises an amplifier, formed by transistors T1, T2 and the variable resistance element comprises the source to drain path of a field-effect transistor T5. The output from the network is fed to an amplifier comprising transistors T3, T4, there being positive feedback from the collector of transistor T4 to the base of transistor T 1 so as to generate oscillations. The amplitude of oscillation is limited by a negative feedback path from the collector circuit of transistor T3 to the base of transistor T2, and which comprises diodes D1, D2; capacitor C2 prevents unwanted highfrequency oscillations. The overall gain round the positive feedback loop may be adjusted to be just sufficient for oscillation, by means of variable resistor r 11  ; resistors R5, RG are also variable and can be adjusted to linearize the frequency/voltage characteristic of the oscillator.

Abstract: 267,735. Lemaster, T. A. April 26, 1926. Dynamos, regulating; driving-arrangements.- Regulating apparatus for maintaining constant the voltage of a continuous-current generator camprises (1) a pilot prime mover 10, (2) a control motor 11 having a normally stationary armature 23 operatively connected with the control element of the main prime mover, and a field 12, rotated by the pilot prime mover and excited from the main generator 18, and (3) an auxiliary generator 32 driven by the pilot prime mover and supplying current to the armature of the control motor. The field 12 of the control motor is driven at the speed at which the armature would rotate normally and in the direction opposite thereto. The armature 23 of the control motor is connected to the prime mover control element by worm gear 38, 39. The auxiliary dynamo 32 is provided with a differential field winding 33 supplied from the main generator 18. If the voltage across the main 17 fall, the field 12 of the control motor and the differential field 33 of the auxiliary generator are weakened, and the cumulative effect causes an increase in the relative speed of the armature and field of the control motor. Since the field speed is constant, the armature rotates and effects the required adjustment of the main prime mover control.

Title: Improvements in or relating to pneumatic linear dimension gauging device

Filed: 1955-04-22
Abstract: 773,711. Pneumatic gauges. SHEFFIELD CORPORATION. April 22, 1955 [April 23, 1954], No. 11669/55. Class 106 (2). A fluid leakage gauging apparatus comprises a diaphragm 35 biased towards an orifice 20 exhausting into a gauging chamber 21, the flow into the chamber being controlled by the proximity of the diaphragm 35 to the orifice 20 and the flow out of the chamber by the work being gauged, the resulting pressures downstream of the controlled orifice being effective on the diaphragm 35 and operating an indicator. A regulated flow of compressed air is led through a passage 16, 18 and an orifice adjustable by means of a needle valve 19 to the orifice 20. A tube 25 connects the chamber 21 with a gauging head (not shown) having orifices from which the flow of compressed air is controlled by the proximity of a workpiece, e.g. a cylindrical head having opposed orifices for gauging cylindrical bores. A passage 27 connects the chamber 21 to a diaphragm 28 on the other side of which are liquid-filled passages leading to a Bourdon tube 31 which operates the indicating device (not shown). While the pressure in the chamber 21 is high, i.e. the workpiece and the gauging head are in close proximity, the diaphragm 35, which is biased towards the orifice 20 by a spring 37, is displaced from the orifice 20 by the pressure and is ineffective to control the flow therefrom. When the pressure in the chamber 21 falls, however, the diaphragm 35 is urged towards the orifice 20 and reduces the flow of air from it. By this means the escape of air when no workpiece engages the gauging head is reduced to a minimum and the range over which the relation between the gauging indication and the work clearance is linear is extended.
