Patent GB-1271866-A (GB)
Title: Apparatus for controlling the jacks of knitting machines
Inventor: FLAD KARL
IPC: D04B15/78
Filed: 1969-06-20
Abstract: 1,271,866. Knitting-machines. K. FLAD. 20 June, 1969 [29 June, 1968; 2 Oct., 1968], No. 31277/69. Addition to 1,200,468. Heading D1C. In a knitting machine in which the needle jacks are selected by strikers 3, pivoted on a rail 1 movable towards the jacks 4, the rail and strikers are positioned so that the magnet affects the armature 17 only, or in an alternative embodiment they are demagnetised each cycle. In the embodiment shown the rail is moved away from the jacks so that the strikers are pivoted out of line with the jacks as the contact cam faces 12. Selective energisation of electromagnets 18 attracts and holds armature 17 carried by a non-magnetisable rod 16, pivoted at right angles to the striker. Selected strikers are thereby held in the unaligned position. Since the armature is at right angles to the striker and carried by a non- magnetisable rod, it only is influenced by the electromagnet. The magnets, which may be arranged in units, are set in paraffin wax. In the alternative embodiment the strikers 110 carried by the rail 107 are held directly by the electromagnets 138 which are given an oppositely directed pulse or pulses when switched off to demagnetise the rail and plate. A condenser may be connected in parallel with each magnet so that it experiences a damped oscillating field of decreasing strength.

Title: Low-frequency correction of television amplifiers
IPC: H03F3/02
Filed: 1937-11-15
Abstract: 500,991. Valve amplifying circuits. RADIOAKT.-GES. D. S. LOEWE. Nov. 15, 1937, Nos. 31288 and 31289. Convention dates, Nov. 14, 1936 and Dec. 12, 1936. [Class 40 (v)] In a mains-fed resistance-capacity coupled television amplifier, the increased amplification at low frequencies, caused by the smoothing circuit R2, C3 is compensated by including in the cathode lead a circuit comprising a correcting resistance R10 in parallel with a short-circuiting condenser C17 and with a correcting condenser C9 which is serially connected with the resistance R16, the correcting resistance and condenser having the values R10=R2/V, C9= C3.V, V being the correct amplification at high frequencies. By this means a continuous flashing of the light intensity of the image and incorrect light intensity values over large areas of the image are prevented. The grid bias is adjusted for optimum conditions by means of the battery 11. The dimensions of the compensating circuit are obtained by oscillographic observation of the output poten. tial obtained from a rectangular grid input potential. A number of stages corrected as above can be connected in cascade, the coupling elements 5, 12 being correctly dimensioned to avoid low-frequency loss. Fig. 1 (not shown) shows a compensating circuit comprising a correcting condenser in parallel with a connecting resistance as disclosed in Specification 459,251.

Abstract: 536,436. Valve generating circuits. HAZELTINE CORPORATION. Dec. 18, 1939, No. 32443. Convention date, Jan. 14. [Class 40 (v)] In a repeater for translating saw-tooth waveforms comprising a pentode or other valve in which the grid-volts anode-current characteristic is substantially independent of anode voltage, the periodic wave applied to the grid includes a pulse which biasses the valve to cut-off during only the initial part of the retrace period. The resulting ouput current and voltage are shown in Figs. 5a, b, c. The repeater is adapted for supplying saw-tooth current to inductive loads, the short pulse being so timed in relation to the inertia effects of the inductance and distributed capacity as to establish current of the desired value through the inductance at the beginning of the trace period. To prevent the current rising more sharply than the input voltage demands, a diode may be connected across the output circuit of the valve. Specification 535,661 is referred to.
