Title: Improvements relating to electric speed indicators
IPC: G01P3/12
Filed: 1928-03-10
Abstract: 286,737. Mombur, G. March 10, 1927, [Convention date]. Impulse speed indicators. - In a speedometer an electromagnetic system operating at a frequency depending on the speed to be measured is utilized to impart movement to an oscillating control member or balance wheel co-operating with a member to serve as a fly wheel to produce a constant speed, the movement of the control member being transmitted to an indicating pointer. As shown in Fig. 1 a distributer 11, operated at a speed proportional to that to be measured, is in circuit with a battery and electromagnet 10 the armature 8 of which is connected by a link 7 to an eccentric pin 6 on a spring-controlled toothed sector 5 gearing with a pinion 4 loose on a shaft 1. The pinion 4 forms part of the control member which comprises a toothed wheel 2 carrying a pin 3 and a toothed disc 25 with a notch 26. Each current impulse through the electromagnet oscillates the control wheel 2 which, on its return movement through a pawl member 12 carried by a fly wheel 13, 16, is operative to rotate the wheel, the motion of which is regulated by an oscillator 14 having pins engaging semi-circular indents on the periphery of the wheel. Co-operating with the disc 25 is a spring-controlled pawl 27 pivotally mounted on a spring-controlled pawl member 30 that engages a measuring wheel 32. The wheel is under the control of a spring 33, Figs. 2 and 4, and is connected through a slot 35 and arm 36 with an indicating pointer 37. The measuring wheel is also provided with a projecting pin 34 in the path of movement of the control pin 3. On the initial movement of the control wheel the pawl 27 is moved from the position shown in Fig. 4 to that of Fig. 5 during which time the pawl 30 is withdrawn to free the wheel 32 to permit the pin 34 to follow the pin 3 and is then operative to hold the wheel 32. The slot 35 provides a slight play for the wheel 32 to prevent movement of the pointer while the wheel is freed. At the end of the forward limit of the control pin 3 a lever 17 is operated to drive a counting-mechanism for registering distance and the notch 26 in the disc 25 at the same time permits return of the pawl 27 to its normal position ready for the next impulse. In a modification the speed measurement is made while the current is flowing by means of an electromagnet the armature of which drives a control wheel at uniform speed. In another form the armature is replaced by a vibrator which may be intermittent or continuous depending upon whether or not it is arranged in the circuit of the distributor. In still another form the control member may be actuated through a repeater device regulating the speed of the balance wheel.

Abstract: 526,119. Control of A.C. motors; controllers. BRITISH THOMSON-HOUSTON CO., Ltd., LIDDIARD, H. W. C., and PETCH, T. H. March 8, 1939, No. 7545. Addition to 512,237. [Class 38 (iii)] Non-regenerative braking.-In the system of control according to the parent Specification a single liquid controller is used both for normal operation and direct-current braking, and when the change to braking is effected an electrically driven hydraulic apparatus such as described in Specification 363,137, [Group XXIX], operates to alter approximately the relative positions of the controller and the control handle. The controller may be. operated by a link 5 from a fluid pressure device A for normal operation, and from a second fluid pressure device B for braking. These devices are controlled by respective control pistons 6 passing through operating pistons 9 and provided with control ports 7, the pistons 6 being operated from the control lever. The selection of the device A or B is effected by operation of a control piston attached to a member 15 in accordance with the operating condition of the motor and when the braking connections are introduced the member 15 is moved to render the device B effective in place of A, the control piston 2 of the device B being positioned to cause movement of the controller in relation to the control handle. In a modification a single servo-motor is employed controlled from the control handle by mechanism including an eccentric the eccentricity of which is altered when the braking connections are set up.

Title: Improvements in or relating to gramophones
IPC: G11B17/16
Filed: 1932-03-14
Abstract: 403,352. Magazine gramophones. VERBURGH, G. J., 251, India Buildings, Water Street, Liverpool.-(Assignee of Walraven, L. D. ; 183, Weesperzyde, Amsterdam). March 14, 1932, No. 7553. Void [Abridged as open to inspection under Sect 91 of the Acts, June 23, 1932]. [Class 40 (ii).] In a magazine gramophone, a pile of records is normally retained on the turntable by a central spindle, the turntable being tiltable and the spindle displaceable axially during the tilting, so that by this means a record can be discharged after being played. The turntable 10 and its driving motor 12 are mounted on a frame 13 which is supported on trunnions 19. An electromotor 20 is provided for effecting the tilting of the turntable through a gear-box, cranks 16, 18 and a link 17. A record-centring spindle 28 extends through the hollow driving shaft 11 of the turntable, and at its lower end has screw-threaded engagement with a bevel wheel 35. This wheel gears with another bevel wheel 3 4, adapted to be rotated, when the frame 13 is rocked, by means of a wheel 29 engaging a segmental rack 31, a pawl and ratchet device being interposed between the wheels 29, 34. When the playing of the top record of a pile on the turntable has been completed, the pick-up arm 24 closes the circuit of the motor 20, which rocks the frame 13 with the turntable. As the tilting begins, an arm 36 on the frame raises the pick-up arm, which thereupon swings back by gravity to engage a stop at the starting position. The pick-up is lowered, under the control of a dashpot 40, as the turntable frame returns to the horizontal position, the played record having meanwhile been discharged. The release of the record is brought about by the action of the mechanism 29 ..... 35 in lowering the spindle 28 sufficiently to allow the record to slide off when the turntable is inclined. The motor switch is opened by the turntable or frame on their return to the normal position.

Filed: 1966-02-23
Abstract: 1,084,664. Break-spinning apparatus. VYZKUMNY USTAV BAVLNARSKY. Feb. 23, 1966 [Nov. 16, 1965], No. 7919/66. Heading D1D. So that the units of a break-spinning frame can be stopped individually for maintenance, cleaning or the repair of a broken end, each unit comprises two housings, one for the spinning chamber, and one for the combing roller and the outlet through which the spun yarn is withdrawn, the housings being rotatably mounted about parallel axes so that they may be swung apart. The housing 17, Fig. 4 for the combing roller 5 and the yarn outlet 41 which also carries an inlet passage 5 for the sliver, a feed roller, and a separator plate 38, is rotatably mounted on a tube 8 common to all the housings. The housing 14 for the spinning chamber is hinged to the frame at 13, its weight and that of the associated driving- pulley 15 causing the pulley to engage a braking-surface 21 when the housings are separated. The tilt of the housing 17 is limited by a spring-catch 16 mounted thereon which engages the housing 14 and helps to tilt it. When the housing 17 is in tilted position, the drive roller 48 of the combining roller is separated from its drive belt 4 and the drive of the feed roller is disconnected in a manner to be described below. When the housings are to be restored to spinning position, the housing 17 is swung towards the housing 14 a spring-urged pin 49 on the former engaging the housing 14 and tilting it back to working position, where the pulley 15 moves off the braking surface to engage its drive belt 2 before the separator plate 38 enters the spinning chamber. The two housings are held in working position by a catch 57 - 18. The feed roller is driven by gearing from a gear 25 which engages a gear on a drive shaft 6 common to all the units which passes through the tube 8. The gear 25 is one part of a clutch with which the other is held in driving engagement by a spring, but which is withdrawn when a solenoid is energized. The solenoid is in circuit with a feeler, the circuit being open as long as a thread engages a feeler 42 near the thread outlet 41. When the thread breaks or is absent, the feeler closes the circuit to disengage the clutch and stop the feed roller; at the same time a signal lamp is switched on. The lamp is disposed within the upper part of the housing 17 the cover of which includes a translucent plate 54 so that it can be seen when the lamp is switched on. A branch circuit across the feeler terminals includes a capacitor and a resistance to prevent sparking, the resistor reducing the voltage across the lamp terminals. The catch 57, 18 can be released manually by a handle 58 to separate the housings and separate the pulleys 15, 48 from their drive belts and move pulley 15 against the braking- surface 21. By thus bringing the spinning chamber to a stop, the delivery of thread is interrupted and the feeler operates to separate the clutch and stop the feed roller.

Abstract: 565,761. Actuation of switches. BIRMINGHAM ELECTRIC FURNACES, Ltd., and LEAN, R. J. May 19, 1943, No. 7949. [Class 38 (v)] A switch is tripped open when the passage of articles through a feed mechanism ceases, and may open the circuit of an induction heating coil and/or the driving motor of the feeding mechanism. The switch comprises contacts 18 normally held in engagement by a spring-controlled lever 16 carrying a roller 15. A synchronous motor 8 is constantly rotated to drive through friction gears 6, 7 and toothed gears 11, 12, a cam 14 on a plate 13 integral with gear-wheel 12, the cam being adapted, after a given travel to engage the roller 15 and cause opening of contacts 18. Wheels 7, 11 are carried on bracket 10 fast with an arm 4 having a raised part 5, which is engaged by a roller 3 on a lever system 1, 2 operated by the articles in the feeding mechanism. Each time an article passes lever 1. and rotates it, the roller 3 depresses lever 4 and disengages wheel 7 from wheel 6, so interrupting the drive and preventing operation of the switch. The gear 12 and cam 14 are then restored by a clock spring 21 anchored between the gear 12 and a collar 20 on the spindle, so as to be tensioned by rotation of the gear 12 in the tripping direction. A stop 22 adjusts the timeinterval required to effect tripping. The lever 1 may be moved in both directions by bylindrica,l articles, such as roller bearings, in depressions in the feeding mechanism.
