Title: Device for regulating the winding-on tension of continuous sheet material
IPC: D06B3/34
Filed: 1966-08-23
Abstract: 1,154,443. Feeding webs. TEXMA MASCHINEN G.m.b.H., [trading as SUCKER GEB.]. 23 Aug., 1966 [26 Aug., 1965], No. 37648/66. Heading B8R. [Also in Division G3] Apparatus for winding web material F, including warp threads, on to a beam 1 comprises a feed roller arrangement 2, 3, 4, of which the roller 4 nearest to the beam 1 is pivotally mounted about the axis 3a of the roller 3 and serves to control the winding speed so as to regulate the web tension, means being provided whereby the position of the roller 4 is adjusted during winding so that the length of the surface of the roller 4 contacted by the web, i.e. the looping angle, remains substantially constant. A pivoted arm 4c carrying the roller 4 is connected by a chain 6 to a chainwheel 8 on a shaft 7. The chainwheel 8 has a toothed rim 9 engaging a rack 10 attached to a piston 11 subjected to a constant hydraulic pressure in a cylinder 12. The shaft 7 is connected by a chain drive 15 to a regulating valve 16 through which oil under pressure may be fed to a device 27 which rotates an adjusting shaft 29 to control the drive mechanism 28 of the beam 1 so that the winding speed is controlled by movement of the roller 4. The shaft 7 carries a cam 20 to which a weight 23 is attached by a chain 22; this arrangement serves to counterbalance the weight of the roller 4 and its associated parts. To achieve the constant looping angle referred to above, a photo-electric device 24 senses the position of the web between the, roller 4 and the beam 1. The device 24 is carried on a shaft 26 movable vertically by a motor 25 controlled by the device 24 so that the device follows the web F as the web position alters with increasing diameter of the beam. Movement of the photoelectric device 24 causes a signal to be supplied by a transmitter 18 to a servomotor 17 which rotates the outer part of the valve 16 relative to the inner part to operate the device 27 so that the winding speed is reduced to allow the roller 4 to move anticlockwise to maintain the looping angle constant. The adjustment of the drive mechanism 28 may be carried out by an electric motor instead of hydraulically in which case the valve 16 is replaced by a potentiometer, the tap of which is adjusted by the chain 15 and the body of which is adjusted by the motor 17. Further, a variable speed motor may be used as the drive mechanism 28. As an alternative to the devices 18, 24, 25, 26, the adjusting shaft 29, which is rotated by the device 27 in proportion to the degree of winding of the beam, is coupled to a transmitter 34 corresponding to the transmitter 18 and connected to the adjusting motor 17.

Abstract: 1283360 Tyre pressure indicating devices MICHELIN & CIE (COMPAGNIE GENERALE DES ETABS MICHELIN) 29 July 1969 [29 July 1968 23 May 1969] 38070/69 Heading B7C A device for monitoring a characteristic of a vehicle wheel, e.g. the pressure of the wheel's tyre, comprises a transmitter and a receiver, mountable on the wheel and vehicle chassis respectively, the transmitter consisting of a permanent magnet and actuating means sensitive to variations of the characteristic for varying the magnetic field of the magnet, and the receiver being sensitive to the magnetic field variations. The receiver comprises a blade switch 17, or alternatively a magnetodiode, a magneto-resistor or a Hall effect cell, which become conducting in the presence of a magnetic field. An hermetically sealed transmitter casing 1 attachable by lugs 3 to a vehicle wheel, houses the permanent magnet 3 and an L-shaped magnetic screen 7 pivotally mounted on a pin 6 in bearings 8, 9. The screen 7, which is biased by a spring 12 to occupy the broken line position of Fig. 2 where it does not screen the magnetic field of the magnet, is held in the screening position shown by a plunger 12 engaging a slot 14 in the screen. The plunger 12 is attached to a diaphragm (40) within a pressure transducer 13 the inlet part of which is connected to the tyre inflation valve by a tube (44). When the tyre pressure falls the diaphragm retracts the plunger 12 to release the screen 7 to move to the broken line position, so that as the transmitter passes the switch 17 during rotation of the wheel the unscreened magnetic field closes the switch which operates via a circuit 55 an audio or visual warning device. Each receiver and transmitter may have their own circuit or be connected to a common circuit for all the receivers and transmitters on the vehicle. The pin 6 is extended beyond the case and has fixed to its end a winged finger plate (52) to indicate that the device has operated and to enable the screen to be reset.

Abstract: 1,259,884. Monitoring arrangements for vehicle supply systems. KOMBINAT VEB FAHRZEUGELEKTRIK RUHLA. 4 Aug., 1969, No. 38936/69. Heading H2H. To prevent misleading operation of a lamp 9 which monitors the operation of a vehicle alternator 1 whose field winding 4 is controlled by a conventional vibratory-contact voltage regulator 5, the relay 6 controlling the state of the lamp via contacts 8 is provided with main and auxiliary windings 16, 17 which ensure that contacts 8 remain open during the various operating positions of the regulator contacts 12, 14, 15. The winding 16 is in series with the field winding 4 and maintains contacts 8 open with full field current corresponding to contacts 12, 14 closed. When the latter open, winding 17 is energized by the voltage appearing across the regulator resistor 13 to supplement the reduced holding force of the winding 16 and so keep contacts 8 open. Closure of contacts 12, 15 produces a reduction in the alternator voltage to restore the regulator to one or other of its previously described contact positions, so maintaining the contacts 8 open. Loss or reduction of the alternator voltage causes closure of contacts 12, 14, reduction of the field current and closure of contacts 8.

Title: Apparatus for automatically releasing the brakes on tiltable metallurgical vessels, for example converters, on failure of the operating voltage
IPC: F16D65/28
Filed: 1963-10-03
Abstract: 996,801. Electric control of brakes. BETEILIGUNGS - UND PATENTVERWALTUNGSG.m.b.H. Oct. 3, 1963 [Oct. 4, 1962], No. 39015/63. Heading F2E. In brake mechanism for electrically driven tiltable metallurgical containers of the kind wherein a normally applied brake is released when the electric driving motor for the container tilting bear is energized, a device is also provided for releasing the brake in the event of failure of the electric supply voltage, such device comprising means exerting a steady force in the brake releasing direction and which is opposed by means dependent on the supply voltage which exerts an opposing force so long as the supply voltage is maintained, whereby failure of the supply voltage causes the brake to be released. In one embodiment, Fig. 1, external shoes 1 are applied to a drum 3 mounted on a driving shaft of a converter tilting mechanism by a steady force Pb acting via a lever 4 and link 2, this force being overcome when the electric driving motor is switched on through control means not shown, causing operation of a device 5 to release the brake. Additional mechanism for releasing the brake should the voltage supply to the motor fail comprises a spring 9 exerting a force P 3 , but normally rendered ineffective by a device 6 which is operative so long as supply voltage is maintained, a slotted link 8 joining the output of the assembly 6, 9 to an extension of the lever 4 permitting normal operation of the lever 4. When supply voltage fails, spring 9 is effective to release the brake until the converter tilts back nearly to its normal position, whereupon a valve 15 is automatically opened which is in series with a cylinder 13 and with a solenoid valve 16 which was opened when supply voltage failed, allowing piston 12 to move and de-tension spring 9 sufficiently to re-apply the brake, thereby preventing oscillation of the converter. In a second embodiment, Fig. 2, the apparatus is as in Fig. 1 except that the assembly of device 6 and the apparatus exerting force P 3  acts via a cable 19 loosely passed over a pulley 18 to the lever 4 to allow the normal operation of the latter.
