  • Device for monitoring portable breathing apparatus
    Patent number: 5738092
    Abstract: A monitoring device for portable breathing apparatuses having a manometer by means of which the pressure in the pressure container of the breathing apparatus is detected, and having a transmitter by means of which a signal corresponding to the pressure is transmitted at regular intervals. The transmitter also has a signal generating device which generates an identification signal which is characteristic of the transmitter. The pressure signal and identification signal are received and tested by a receiver. If the identification signal matches an identification comparison signal stored in the receiving device, the measured pressure value is displayed on a display device.

  • Method and apparatus for orienting fibres
    Patent number: 4885823
    Abstract: For the formation of fleeces or webs with parallelized, hooklet-free fibres for pattern production or for spinning mills, a raw material undergoes preliminary drawing in a preliminary drawing frame and is then supplied to a feed arrangement, through which the raw material is supplied to a clamping point of an extracting device formed of two clamping rollers. The clamping rollers running at a higher speed than the feed speed of the feed arrangement pull out fibre tufts disentangled and parallelized on one side. Then the tufts are fed to a suction drum for doubling purposes. From the suction drum the web formed with one disentangled side is fed into a further preliminary drawing frame, into a second feed arrangement, then into a further extracting device and thereafter into a further suction drum.
