Title: Improvements in or relating to clutch mechanisms
IPC: F16D67/02
Filed: 1930-11-08
Abstract: 368,703. Sewing-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. and KEALL, F. B., Union Works, Belgrave Road, Leicester. Nov. 8, 1930, No. 33643. [Class 112.] Starting-and-stopping gear.-In curved hooked needle shoe sewing-machines of the kind described in Specification 332,313, [Class 112, Sewing &c.], and in other machines, the clutch and brake operating gearing described in Specification 720c/07, [Class 80, Mechanism &c.], is modified to prevent jamming of the operating-parts and to prevent shock. In that gearing, a swash-member carried in a slot in an axially-movable combined clutch and brake member turning with the main machine shaft causes the oscillation of a member the stopping of which causes the disengagement of the clutch and the engagement of the brake. In this Specification the said oscillating member 36 is stopped by a projection 34 on a member 32, which rises when the treadle-rod 62 is released. The brake element 2 which is engageable by the axially movable brake member is free on the machine shaft 4 and is connected by a rod 8 to an adjustable dashpot so that the element 2 is rotated slowly to stop the machine without shock and is then returned to its original position by spring means. To start the machine, the treadle is depressed and a hook 64 on the treadle-rod 62 engages a pin 38 on a trip-arm 40 turning on a pivot 42 on the brake member 2, the stop-member 32 turning on the pin 38 but being maintained in vertical position by a spring 60, which holds it against a stop on the arm 40, and by a lever 46 pivoted on a pin 48 on the arm 40. When the treadle is released, the arm 40 and stop 32 rise under the influence of a spring 66. The clutch is thus disengaged and the brake engaged, so that the brake member 2 swings, carrying with it the arm 40 so that the lever 46 rotates a tumbler 50 and passes beyond it in order that when the brake member returns the lever 46 may be depressed by the cam 54 on the tumbler to release its other end from the projection 44 on the stop-member 32. The pressure of the projection 34 on the oscillating member 36 is then maintained only by the spring 60 and is thus relieved to facilitate easy restarting. In order to ensure that the stop-member 32 may rise to stopping-position only when the member 36 is clear thereof, a spring-pressed plunger 70 projects itself below the member 36 when the arm 40 is lowered and, when the treadle is released, prevents rise of the member 32 until the plunger is pressed back by movement of the member 36 to the left. In a modified device, Fig. 7, for achieving this result, a hook 71 on the stop-member 32 is engaged by the end 72 of a lever 73 turning on a fixed pivot, the hook being released only when a suitably placed cam 77 on the rotating clutch and brake member engages a lever 76 pivoted on the treadle-rod 62, which must be released before this operation takes place.

Title: Improvements in or relating to circuit arrangements for generating currents of predetermined waveform
IPC: H03B5/10
Filed: 1956-11-05
Abstract: 840,697. Cathode-ray tube circuits. FERNSEH G.m.b.H. Nov. 5, 1956 [Nov. 4, 1955], No. 33696/56. Class 40(7). [Also in Group XXXV] In order to improve the focusing of the electron beam in a television tube an additional component is introduced into the focusing field, this component being generated by an energy recovery type of circuit comprising an inductor 1, a capacitor 2 and switching means 3, 4 connected across a direct current supply, the power demand of such a circuit on the supply being less than that used in the conventional focus correction circuits. With the switches 3, 4 in the position shown in full line the capacitor 2 will charge from the source by way of the inductance 1 until the charging current becomes zero when the potential acquired by the capacitor 2 will be twice the supply voltage V, that is 2V. At the instant of zero current the switches 3, 4 are moved to the position shown in broken line thereby reversing the capacitor polarity. The voltage acquired by the capacitor now aids the supply voltage so that the current in the inductance 1 is that produced by the voltage 3V. At each reversal of the capacitor polarity the voltage thereacross will increase until it is limited by the damping inherent in the circuit. The waveform of the current produced in the inductance is a half sine wave but this may be modified if desired by the use in the circuit of non-linear components. In a practical embodiment of the circuit the inductance is in the form of a centre tapped on to transformer 6 with the capacitor 2 in parallel therewith, the combination being connected in series with the primary winding of a transformer 5, the switching means comprising two thermionic valves 3, 4 having the control grids supplied at 8, 9 with antiphase control signals which signals have a frequency of half the repetition frequency of the current which is required to be produced in a coil 1 connected to the second winding of the transformer 5. A battery 7 is connected in the circuit of the coil 1 to prevent a current of double frequency occurring therein. The valves 3, 4 may be replaced by other devices such as transistors.

Filed: 1922-12-14
Abstract: 212,647. British Thomson-Houston Co., Ltd., Hastings, H. C., and Sarjeant, C. J. Dec. 14, 1922. Automatic circuit-breakers; cut-out arrangements.-Circuit-breakers in a feeder circuit supplied from a bus-bar which may be connected to one or more generators according to the load, as for example in automatic sub-stations, have their overload calibration altered, automatically, in accordance with the number of connected generators by the use of contactors arranged to vary, automatically, the resistance in the holding coil circuit of the breaker which may be of the kind having a demagnetizing release as described, for example, in Specification 125,279. As shown applied to such a circuit-breaker 1 in a feeder 37 connected with a bus-bar 30 supplied by one or both of the generators 35, 36, the circuitbreaker is closed electromagnetically by the coil 11 acting through the armature 9 and is maintained closed by the holding coil 3 until released by the demagnetizing coil. The coil 11 is energized by closing the push-button switch 21 which connects the winding 3 to the control bus-bars 50 in series with the winding 16 of a contactor (which, in turn, closes the circuit of 11) through the .contactor 41 which is closed by current through the contact 43 of an auxiliary switch interconnected bv linkwork with the main switch. When the circuit-breaker closes, the contact 43 is opened, 16 is de-energized and, consequently. 11 de-energized. A resistance 22, variation of which by varying the current in the holding coil 3, alters the setting of the circuit-breaker. is connected in parallel with the coil 16. The opening of the circuit-breaker closes the contact 15 5 which short-circuits 16 and 22 so that, the full control voltage is applied to the holding coil 3. This voltage is, however, immediately reduced bv the opening of the contact 43 which removes the short-circuit from the resistance 22 by causing the opening of the contactor 40. The current in the holding coil is now controlled by the resistance 22 in series with it and the setting of the circuit-breaker is at its lowest and correct when one only of the generators is on the bus-bar, the back contacts 32, 34 of the bus-bar switches being connected in series. complete a circuit for the contactor 46 which has an operating coil 23. In closing, this contactor short-circuits 22 and the circuit-breaker setting is, momentarily, at a maximum. Contactor 46 closes the operating circuit of a second contactor 47 which in closing its contacts short-circuits a portion, onlv, of 22 and removes the full short-circuit across it. The circuit-breaker is now on the higher setting determined by the portion of the resistance 22 which is pot short-circuited. If one of the generators is disconnected, the setting of the circuit-breaker automatically returns to the lower value.

The abutments, Fig. 6, are formed with tongues 52 co-acting with grooves 48 in the sides of the finger and are associated with divergent wire guides 51 and cutting members 57 which co-act with the lower edges of the finger. The latter is oscillated by a transversely-slidable bar 35 which is reciprocated by a cam 40 on a shaft 41 and carries bars 46 fitted with screws 47 engaging the sides of the finger, the screws being adjusted to produce the required pressure between the finger and abutments and locked in position by nuts 47<SP>1</SP>. The twisting device comprises a hook 84 at the end of a shaft 80 co-operating with a fixed parallel rod 85 which is bent away from the shaft at its lower end, the shaft 80 being driven by chain and sprocket gearing 77, 81 and 82 from a stub shaft 75 which carries a bevel gear 76 meshing with a mutilated gear 67 on a transverse shaft 62 which is driven through a manually or automaticallyoperated one-revolution clutch. The shaft 41 is driven through chain and sprocket gearing from the shaft 62. Assuming that a bale 24 has been formed and the wire extending in usual manner from the supply through a guide 88 and around three sides of the bale is gripped at its end between the finger 33 and the right hand abutment 49, the needle 26 carries a loop of the wire across the rear end of the bale, as shown in Fig. 2, so that the portion between the needle and bale passes through a guide 91 and between the finger and the left hand abutment. The ends of the tie are then embraced by the hook 84 as it commences to rotate and the finger is then swung to the left to release the wire extending over the upper side of the bale, sever the loop and grip the portion extending from the needle to the supply. The free ends of the tie are then twisted by continued rotation of the hook and the needle is returned to its original position leaving the wire extending from the supply to the gripper ready.for the next baling operation. The tying mechanism is duplicated.
