Abstract: 1406152 Making expanded metal EXMET CORP 2 May 1973 20967/73 Headings B3W and B3A An elongated sheet 9 is formed into expanded metal by means of a plurality of toothed wheels 18-20, each co-operating with a shearing edgeas shown the edge of a roller 25-and each being continuously rotated to form a series of longitudinally aligned spaces opening about an axis perpendicular to the longitudinal direction in which the sheet is moved. The wheels are staggered laterally to produce laterally offset lines of openings. Each wheel has a sprocket shown as 33-35 respectively, a single chain 36 engages all the sprockets and means, sprockets 41, 42 as shown, engage the chain between the wheels forming each successive pair of wheels to enable the relative angular position of the wheels of a pair to be adjusted, while the sprockets and chain remain meshed, so that each wheel is half a tooth pitch out of phase with the wheels immediately fore and aft of it and each opening is located between two successive openings in each adjacent line of openings. The sprocket 33 is driven by a motor 32. To adjust the angular phase of, say, wheels 18 and 19, the arm 43 and thus sprocket 41 is raised or lowered by means of an adjusting screw 46 which rotates the wheels 18 and 19 in opposite directions. The chain is tensioned by an idler sprocket 37 mounted on an arm pivotable on the shear frame 10 and urged downwards by a spring 40. Rollers 21 and the rollers 25 grip the sheet during the shearing. In an alternative embodiment, Fig. 6, a toothed wheel 20, 20<SP>1</SP> is mounted at each end of a roller 21 to act on the edges of a strip to be expanded with the spacing between the two wheels decreasing with each successive roller so that the whole strip is expanded. Alternatively, a central imperforate strip may be left to be slit by a disc cutter 58. A reciprocating transverse shear may cut the expanded metal into lengths, to form, e.g. electrodes.

Abstract: 632,408. Valve generating circuits; frequency modulation. FAXIMILE, Inc. Aug. 5, 1947, No. 21210. Convention date, Aug. 10, 1946. [Classes 40 (v) and 40 (vi)] Reciprocally-coupled valves are interconnected by phasing networks in such a way that variation of the gain of one of the valves varies the frequency of oscillation. As shown in Fig. 2, the anode of valve 12 is coupled to the grid of an amplifier 10 by a phase-advancing network 13, 14, and the amplifier output is passed without phase-shift to the grid of the valve 12. As a result, the anode current IP has two components, one of which is in phaseopposition to the anode voltage EP and provides the effect of a negative resistance, the other component being in phase quadrature with the anode voltage and providing the effect of an inductance. The value of this inductance is determined by the gain of the amplifier 10 which is dependent on the voltage of the signal source 15, and the frequency of the oscillations produced is determined by this effective inductance in association with the capacity 18 in the anode circuit of the valve 12. In a modified circuit (Fig. 7, not shown), the capacity 13 is replaced by an inductance, and the parallel combination of capacity 18 and resistance 17 by a series combination of inductance and resistance. In a further modification, Fig. 9, the valve 12 is coupled to the amplifier 10 by a common cathode resistor 39, and the phase-shift is introduced by the coupling 28, 40 from the anode of amplifier 10 to the grid of the valve 12. The oscillator may be used for generating a sub-carrier for facsimile telegraphy, or for giving a controllable scanning frequency in the same art.
