Abstract: 643,662. Electric filters. SCOTT, H. H. Jan. 7, 1947, No. 545. Convention date, Feb. 9, 1946. [Class 40 (viii)] Automatic volume and tone controls of the type described in Specifications 643,854, 645,343 and 656,545, [Group XXXIX], employ filters using reactance tubes. A low pass half-section constant K filter, Fig. 1, with input terminals 15, 16 and output terminals 17, 18, comprises a series inductance 10 and a variable shunt capacitance in the form of a capacitative reactance tube 8. A control voltage across terminals 23, 24 varies the cut-off of the filter, a condenser 14, if employed, filtering the control voltage by attenuating the high audio-frequency components. By operating the filter from a low impedance Z 1 and feeding a high impedance Z2, resonance is obtained to make the attenuation of the high frequencies in the region of cut-off less apparent. Condensers 35, 102 may be inserted, the condenser 35 and inductance 10 forming a high-pass filter to prevent spurious low audio frequency components of the control voltage appearing in the output. To improve the attenuation above cut-off, the series inductance 10 may be replaced by a resonant circuit 10, 38, Fig. 3, and an inductance 34 may also resonate with a condenser 35 or with the simulated capacitance of the tube. The control voltage may be applied to an additional control electrode 56. The reactance tube 8 may act as an inductance (Fig. 4, not shown). According to the values of the components, the filter of Fig. 5 may be band-pass or band-elimination.

Filed: 1926-01-11
Abstract: 268,888. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Jan. 11, 1926. Periodic; actuated by driving-mechanism disengagers.-A chain-stitch curved hook-needle for sewing a continuous shoe inseam of a series of stitches is provided with means that operate automatically on stopping the machine to engage and hold, and also to cut, the thread between the looper and the work, the thread-handling devices being manipulated to give up thread to prepare the machine for re-starting. The invention IS described with reference to a machine which is adapted to be stopped in a predetermined position, the thread holding and severing means operating in conjunction with a thread feeding finger and being controlled by the stop mechanism. At the completion of sewing, a treadle rod 264 is released by the operator and is pulled upwards by a spring 266 to release a spring- pressed locking-pin 224 mounted in a carrier 226. This pin engages a recess in the lower end of a bell-crank lever 218, the upper end of which carries a cam roll 220, which, in the normal running of the machine, runs freely in a cam groove 222 on a sleeve 204 carrying a clutch member 202 at its upper end and a brake member 210 at the lower end. When the pin 224 is engaged with the lever 218, the carrier 226 is pulled to the right against the action of a spring 230 and is held in this position by a latch 238. The lever 218 thus disengages the clutch member 202 by forcing the sleeve 204 downwards against a spring 214 and presses the brake member 210 into the brake member 212 to stop the machine with the needle retracted from the work. Specification 268,885, [Class 112, Sewing &c.], is referred to.

Abstract: 398,498. Converting. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Bivens, M. E. ; 17, Glen Avenue, Scotia, New York, U.S.A.) Jan. 11, 1932, No. 793. Convention date, Jan. 9, 1931. [Class 38 (ii).] In a series-type inverter having discontinuous control valves 13, 18, the grid circuits of which each include one of the secondary windings of a grid transformer 21, unilaterally conducting devices 26 are connected in parallel with these windings and means are provided for applying a negative bias to the control grid of the non-conducting valve while the other is conducting current so that abnormal conditions in the circuit supplying the transformer 21 do not cause both valves to conduct simultaneously and short circuit the D.C. supply 10. The valves 13, 18 are of the type which commence to conduct current when the grid is slightly negative. The grid circuit of each valve includes also a unilaterally conducting device 23 and the secondary 24 of a transformer 25 the primary of which is connected in the A.C. output circuit. Positive half-waves of potential in the winding 20 are short circuited by means of a unilaterally conducting device 26, a resistance 27 restricting the current. During the period when the valve 13 is conducting, the potential induced in the winding 24 is in such a direction that the unilaterally conducting device 23 is non-conducting. Hence the total p.d. between the cathode and grid is approximately zero. At the same time the potential in the winding 34 is in such a direction that the device 33 is conducting and current flows through a resistance 36, thus introducing into the grid circuit of valve 18 a large negative biassing potential, which is effective to maintain this valve non-conducting while the valve 13 is conducting current. If the valves are of the type that require a small positive bias on the grid to initiate conduction, a small resistance is inserted in series with the device 26 in each grid circuit. Specification 347,474 is referred to.
