Abstract: 1,035,513. Aerials. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Jan. 25, 1963 [Jan. 25, 1962], No. 3311/63. Heading H4A. The electrical length of a passive element 2 placed adjacent and parallel to a half-wave dipole 1 is varied between just less than half-awavelength (Fig. I, not shown) to just greater than half-a-wavelength (Fig. 2, not shown) thereby causing the element 2 to act as a director (Fig. 1) or a reflector (Fig. 2) and switching the direction of the beam. The variation in electrical length of the passive element 2 which comprises two collinear portions is achieved by connecting a variable electronic reactance between the adjacent ends of the portions. This variable reactance may be a reactance valve (Fig. 3, not shown), a solid anode or a cavity magnetron (Figs. 4 and 5, not shown), a klystron (Fig. 6, not shown) or a semiconductor diode (Fig. 7, not shown). The Specification also refers to the use of a telescopic passive element whose length may be varied mechanically.

Title: Weighing device and method
IPC: G01G11/04
Filed: 1961-01-30
Abstract: 918,895. Measuring weight electrically. RASKIN, S. H. Jan. 30, 1961 [Jan. 28, 1960], No. 3410/61. Class 40 (1). The weight of a moving load is determined by measuring the deflection or stress at a central portion of a beam rigidly supported at its ends, the configuration of the beam cross-section being such that the forces introduced by the load movement have no appreciable effect on the stress in the beam. Fig. 1 shows a side view of a railway truck wheel 16 rolling at a velocity T over a weighing section of a beam 12. This beam is rigidly supported at its ends 10, 11 on a base 4 and its centre section is located over a cavity in the base. The cross-section of the beam and of the truck wheel is shown in Fig. 2. The centre of gravity of the section coincides with the point at which the wheel contacts the rails and this point is precisely over the centre of the unsupported section of the rail. Vertically below the centre of gravity on the lower face of the beam is a strain gauge of known type. The maximum resistance of the gauge is the measure of the stress in the lower face of the beam when the wheel is directly over it. The Specification explains that when the centre of gravity of the section coincides with the point of application of the force the movement of the neutral axis produced by horizontal forces introduced by the rolling friction of the wheels has no appreciable effect either on the bending moment at the centre point or on the stress at the point of application of the strain gauge which stress will be due to the bending moment at the section only. A duplicate arrangement to enable the total weight on an axle to be measured may be used and by adding the weight from all wheels the total weight of the truck may be measured. Fig. 7 shows an arrangement used for measuring the weight of a road vehicle. The beam crosssection is different but again the centre of gravity of the cross-section coincides with the point of application of the load at the intersection of the vertical and transverse axes of the beam. The arrangement of Fig. 8 is used for measuring the weight of a metal ball 32 which rests at points 34, 35, the resulting force at these points passing through G. Figs. 9 and 10 show an arrangement for measuring the weight of granular material on a conveyer belt 40. This conveyer is provided with side belts 45 which prevent the material from contacting the side walls of the beam. The weight is measured by a strain gauge load cell 43 situated beneath the centre of the unsupported length of the beam which measures the deflection of the beam. Horizontal forces cause the point of application of the load cell to the beam to move horizontally a distance e but provided the distance is small compared with the distance L, L<SP>1</SP> no appreciable error results.

Abstract: 676,714. Valve generating circuits; generating high-frequency oscillations. STANDARD TELEPHONES & CABLES, Ltd. Feb. 9, 1951 [Feb. 10, 1950], No. 3472/50. Classes 40 (v) and 40 (vi). A circuit for deriving from an input frequency a F an output frequency equal to - F, where a b and b are different integers whose values are independent of F comprises a modulator which produces the output frequency by mixing the input frequency with a further frequency obtained by converting the output frequency to a lower frequency. The use of the lower frequency avoids the excessive frequency modulation resulting from the frequency multiplication necessary when a higher frequency is used. As shown in Fig. 4, frequency of 499 kc/s. is converted into a frequency of 256 kc/s. and common fractions thereof by mixing the 499 kc/s. with a frequency of 243 kc/s. derived from the 256 kc/s. by a series of dividers and multipliers. The circuit described enables common fractions of a frequency which is a large prime number (such as 499) to be obtained. One of the multipliers (79) comprises a synchronized oscillator as this ensures that the circuit is self-starting. In other embodiments, Figs. 1, 3 and 5 (not shown), frequencies of 72 kc/s. and common fractions thereof are produced from a frequency of 120 kc/s., 64 kc/s., and common fractions thereof are produced from 124 kc/s. and 128 kc/s. and common fractions thereof are produced from 124 kc/s. Other frequencies are also produced by multiplying, dividing and mixing the various frequencies available in the circuit. A suitable frequency divider for use in the circuit comprises a divider dividing by P in parallel with a divider dividing by Q, the two outputs being mixed to produce an overall ratio of PŒQ/PQ, Fig. 6 (not shown). In Fig. 2 an output frequency obtained from one part of the circuit is applied to the primary winding of a double hybrid transformer. Frequencies of 72 kc/s. and 4 kc/s. are applied respectively to the mid-points of the two secondaries respectively so that combinations of 16 kc/s. and 72 kc/s. are produced in the output of a modulator valve connected to the first secondary and combinations of 16 kc/s. and 4 kc/s. are produced in the output of a modulator valve connected to the second secondary. The balancing resistors 31 and 32 are adjusted so that 72 kc/s. does not appear in the second secondary and 4 kc/s. does not appear in the first.

Filed: 1945-02-14
Abstract: 636,871. Uniting by fusion. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 14, 1945, No. 3667. Convention date, Feb. 17, 1944. [Class 83 (iv)] In arc welding with helium or argon-shielded tungsten, thoriated tungsten or tantalum electrodes, the alternating current supply has an open circuit voltage greater than that at which complete current rectification of the arc occurs, and great enough to cause current flow in both directions through the arc. For aluminium and its alloys the voltage wave as shown by an oscilloscope is substantially rectangular when the work is positive. With argon the voltage is at least 145 and preferably greater than 200; with helium the voltage is at least 280 and preferably greater than 380. The change from unsatisfactory to satisfactory conditions may occur at any voltage in these ranges and its cause is unknown. It is accompanied by a fall in arc voltage and current. With a 40 mil. arc length in argon an arc voltage of 27 to 32 and current of 60 amps. falls to 13 to 15 volts and 55 amps. when the weld becomes satisfactory. In helium the current falls from 80 to 55 amps. and the voltage from between 60 and 80 to 13 to 15. A gas-arc torch, used also with low carbon steel, brass, copper, magnesium, stainless steel, &c. comprises a # inch diameter electrode 10 gripped in a spring collet 11 at one end of a copper tube 12 supplying the current and gas. A steel projecting tube 14 insulated from the tube 12 supports a nozzle 15, and the torch may be hand or machine operated. Using 55 amps. in argon at 9 cubic feet per minute and a linear feed of about 8 inches per minute the arc voltage for a tungsten electrode is 14.5 with a 40 mil. gap to 21 volts for a 250 mil. gap. Similar figures are given for thoriated tungsten and tantalum electrodes and for helium. It is stated that the minimum voltage for complete rectification is 68 and that increase of voltage produces current flow in both directions with a resultant D.C. measurable with a magnetic oscillograph and having an associated voltage wave rectangular'when the work is positive and the A.C. a maximum and sinusoidal when the A.C. is a minimum. In a modification highfrequency high voltage may be supplied across a low-voltage arc.

Title: Improvements relating to conveyors

Abstract: 788,049. Endless conveyers; jigging conveyers. STAMICARBON N.V. Feb. 8, 1955 [Feb. 17, 1954], No. 3740/55. Class 78 (1). An endless conveyer for conveying coal along the mine face to the gate conveyer is provided with a plate 5 which catches conveyed material which has failed to leave the conveyer at the delivery point to the gate conveyer, but which falls from the conveyer at the commencement of travel along the return run, the plate being reciprocated so as to deliver the material on to the gate conveyer. The plate is suspended from the conveyer frame 14 by chains 7 (Fig. 1, not shown) and bars 8, the bars 8 being connected to each other by a shaft 13 rotatably supported in the frame 14, springs 15 normally pulling the bars against stops 16 on the frame. When the face conveyer is a scraper conveyer, each scraper 21, as it commences to move along the return run, strikes the arm 20 of a lever 19, whereby a stop plate 24 on the lower arm 23 of this lever thrusts against bars 17 secured on the shaft 13, whereby these and lever 19 are swung as a unit clockwise about the axis of the shaft 13 and the plate 5 moves forward. A spring 25 normally holds the stop plate 24 against the bars 17. When the scraper moves past the upper end of the arm 20, the arms 8 and plate 5 are swung back rapidly by the springs 15. By this movement the coal is advanced along the plate 5 and is eventually delivered to the gate conveyer: The plate 5 extends over the entire width of the face conveyer and over the width of the space between this conveyer and the face, along which a coalgetting machine 6 is reciprocated. If the conveyer is driven in the opposite direction, e.g. for transporting equipment at the mine face, rocking of the member 19 by the scrapers does not effect reciprocation of the plate 5. When the face conveyer consists of an endless belt, the lever 19 is intermittently displaced by an arm or arms carried by a roller driven by the belt.
