  • Patent number: 5270951
    Abstract: A method of storing in a memory having a predetermined number of storage spaces signals representative of deviations in the tension continuously monitored in a plurality of strands of yarn running in a textile machine. The signals from the individual strands are sequentially fed into a memory and are initially stored in the available spaces. Once the memory is filled, the highest number of earlier stored signals is reduced by later signals being written over them.

  • Patent number: 4797062
    Abstract: A device for moving a gas at a subatmospheric pressure with a screwthread-like device on at least one of the facing surfaces of a rotor spacedly surrounded axially by a relatively-rotatable stator insulates the stator from a housing for the device to prevent thermal variation of the space between the rotor and stator and, thus, keeping the gas-moving action constant.
