Title: Improvements in or relating to electric circuits comprising elements with non-linear characteristics
IPC: H03H7/01
Filed: 1933-12-15
Abstract: 422,977. Impedance networks. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and ESPLEY, D. C., c/o General Electric Co., Wembley, Middlesex. Dec. 15, 1933, No. 35352. [Classes 40 (iii) and 40 (v)] For enabling currents of impure wave-form to be transmitted with minimum distortion through an amplifier or other apparatus having a non-linear characteristic, a phaseshifting network is provided whereby the ratio of peak current to r.m.s. current is reduced prior to transmission. The invention is particularly applicable to voice-frequency telegraph systems of the kind described in Specification 389,917. The wave-form a, Fig. 1, can be converted to the wave-form b by shifting the phase of the third harmonic in relation to that of the fundamental by means of the network shown in Fig. 2, which offers a constant input impedance R at all frequencies if L11/C21=R<2>; it therefore produces no amplitude-distortion. It produces the required phase-shift if R /L11 and RC21 bear a specified ratio to the frequency of the fundamental.

Abstract: 1,073,945. Winding bobbins. SCHWEITER ENGINEERING WORKS Ltd. Aug. 28, 1964 [Aug. 30, 1963], No. 35382/64. Headings DID and D1J. Winding apparatus, of the type having a series of winding stations B movable relative to a unit C which knots broken threads or supplies fresh cop packages, has means to determine the absence of a cop package in the delivery position 30 of the unit C and, in which eventuality, to prevent the interruption of the relative movement when a new cop package is required, but allow the relative movement to stop when there are broken ends to be knotted by unit C. As described the stations B are mounted on a rotatable turret D and each have yarn feelers 50, 51 to determine respectively the exhaustion of cop 2a or a broken thread and to actuate, through armature 18a, 19a of electromagnets 18b, 19b, switches 18 and 19. The cop holder 30 which is pivoted into a cop delivering position by lever 31 has a trap door which in the absence of a cop is spring-pressed upwardly to actuate a switch (43). This switch causes the cop magazine to be rotated by an indexing lever to supply a new cop to holder 30. The control circuit, Fig. 5 (not shown), prevents the relative movement being interrupted when both switches 19 and 43 are closed-i.e. when, although a fresh cop is required, one is not available in position 30.

Abstract: 1518703 Non-volatile semiconductor memory device AGENCY OF INDUSTRIAL SCIENCE & TECHNOLOGY 27 Aug 1975 [29 Aug 1974] 35382/75 Heading H1K In a non-volatile memory device in the form of an MIS transistor with elongate parallel source and drain regions which may be permanent or voltage-induced, the gate, source or drain constitutes a resistive path normal to the source-drain channel and has electrodes at its ends to enable a voltage gradient to be produced in it. In one embodiment with an MNOS gate structure the voltage gradient in the resistive gate enables a length of the nitride-oxide interface proportional to the write voltage or a section of it at a location determined by said voltage to store injected charge. In a modification the source (drain) region includes a resistive strip to enable the drain (source) to act, via a conductive channel formed beneath a writevoltage selected section of the interface, as a tapping on the resistive strip or to constitute one terminal of a variable length of the strip. In a further modification the resistive strip is constituted by a voltage-controllable inversion layer formed beneath a strip form insulated electrode. In these modified forms the gate may also be resistive and provided with electrodes to produce a voltage gradient along the source-drain direction.

Filed: 1928-12-01
Abstract: 305,530. Union Special-Maschinenfabrik Ges. Feb. 6, 1928, [Convention date]. Thread cutters for severing chained stitches between successive articles, are put into operation by the descent of the presser foot when no material is thereunder. An arm 15, Fig. 1, is continuously oscillated by link and lever connection with the main shaft 8. The movable blade 27 is mounted on a bell crank lever 25 pivoted on a stud 24 carried by the presser bar 3. When the presser foot 2 rides over the edge of one of the articles to be sewn, Fig. 5, it descends, allowing the lever 30 to descend to bring a knifeedge 32 into the path of the bifurcated end 16 of the lever 15. On the next oscillation of this lever, the lever 30 is pulled to the left, tilting the lever 25 against the spring 28 and bringing the blade 27 into contact with the fixed blade 19, to sever the chain of stitches s between the articles. A rod 34 carried by a bracket on the presser bar 3 can be adjusted by a grub screw to such a height that it prevents the fall of the knife edge into the path of the lever 15, so putting the cutting mechanism out of action.

Abstract: 1,081,852. Frequency discriminators. SIEMENS A.G. Aug. 19, 1965 [Aug. 20, 1964], No. 35526/65. Heading H3A. A frequency discriminator comprises an inductance 1 and a capacitance 2 fed with the input through respective high resistances 3 and 4, Fig. 1, so that the voltages across them are in anti-phase; and these voltages are rectified and combined to give the output. In Fig. 1 the output is taken between the two rectifier circuits and is balanced with respect to earth; in Fig. 2 (not shown) the output circuit is modified to give an unbalanced output. In modifications the resistances (3 and 4) are replaced by a tuned circuit resonant at the mean frequency of the discriminator. The input may be applied to a centre tap of the inductance (15) of the tuned circuit, Figs. 3 and 4 (not shown), or to the junction of two equal capacitors (16<SP>1</SP> and 16<SP>11</SP>) of the tuned circuit, Figs. 5 and 6 (not shown). The tuned circuit introduces a phase shift with frequency which steepens the slope of the discriminator characteristic; this effect may be increased by connecting a further tuned circuit across the input terminals, Figs. 7-10 (not shown).

Title: Improvements in or relating to guards for machines
IPC: F16P3/04
Filed: 1961-10-04
Abstract: 955,562. Machinery guards. J. E. THOMPSON. Jan. 4, 1963 [Oct. 4, 1961], No. 35800/61. Heading F2J. In a guard arrangement for an index cutting machine described in Specification 955,561, a guard 86 first performs a movement into the safety position, in order to determine that position, and subsequently detects the presence of a foreign body at any position of travel of the guard member into the safety position, and switch means associated with the guard are arranged to initiate the operation of the machine after a, guard setting cycle and when the guard reaches the safety position without having encountered any foreign body. The guard 86 is guided by rearwardly extending arms 91 and is carried by links 89 from arms 87 secured to a shaft 83 which is adapted to be rotated, in order to lift or lower the guard, by means of a lever 85 actuated by a piston rod of a compressed air cylinder 84. A switch arm 96 is rotatably mounted on the shaft 83 between fibre discs 94 arranged between plates 95 secured to the shaft. On actuation of a foot switch 75, the switch arm 96 is moved upwardly, by a ram head 100, to actuate an arm 101 of a switch 102, against the frictional resistance of the discs 94. The main foot switch 76 is then depressed causing actuation of the guard cylinder 84 to effect lowering of the guard to touch the papers or book to be cut. As the guard descends, friction slipping occurs between arm 96 and the discs 94, thus effectively setting the guard height in relation to the rotary position of the arm 96 on the shaft 83. Release of the main foot switch 76 causes the guard to be raised and a second depression of the switch 76 causes the guard to be lowered again, the arm 96 actuating the arm 101 of switch 102 thereby initiating the operation of the machine.
