  • Vibration isolating coupler for reducing vibrations in a drill string
    Patent number: 11603714
    Abstract: A vibration isolating coupler including a first coupler portion, a second coupler portion including an external surface and an internal surface portion, and a vibration isolating portion extending between the first coupler portion and the second coupler portion. The vibration isolating portion including a first solid annular portion and a second solid annular portion. The vibration isolating portion including a plurality of slots extending from the first solid annular portion toward the second solid annular portion forming a plurality of vibration isolating elements. Each of the plurality of vibration isolating elements is disconnected from adjacent ones of the plurality of vibration isolating elements by a corresponding one of the plurality of slots. The plurality of vibration isolating elements enabling torsional rotation of the first coupler portion relative to the second coupler portion.

  • Process for determining the odor-inhibiting properties of textile auxiliaries
    Patent number: 7051572
    Abstract: Gaseous or volatile substances which are either themselves odor-active or components of odor-active mixtures of substances are applied to fabrics. The amount of these substances adsorbed by the textiles is then determined. It is then determined what amount of these substances is desorbed again by the textiles upon storage. Comparison of the results which are obtained on textiles which had been finished beforehand with textile auxiliaries with the results of non-finished textiles enables statements to be made regarding odor-inhibiting properties of textile auxiliaries.
