  • Patent number: 5699702
    Abstract: There is disclosed an improvement in rotational wrenching tools used in the aerospace industry to apply a fastener nut to a fastener pin at a limiting, preload torsion. The pins used for the fasteners have an end recess which receives a rotational stationary key that is supported in the tool by a key holder which is slidably received in a central passage of the rotationally driven socket sleeve of the tool. This invention provides a first rotational detent at the forward end of the key holder and the central through passage and a first spring to bias the key holder axially forward into engagement with said first rotational detent to cause the key holder to rotate with the sleeve and thereby facilitate engagement and disengagement of the key with the fasteners. The invention also provides a second rotational detent at the rear end of the key holder and the housing to rotationally immobilize said key holder during run-up of the fastener nuts on the fastener pins.

  • Patent number: 5656309
    Abstract: There is disclosed a stable animal feed supplement suspension which is prepared by forming a stable liquid gel in concentrated food industry by-products such as by-products of the dairy industry, such as whey permeates, delactosed whey, and by-products of the fermentation industry, such as whey and corn sweet water. These by-products have not been used with any significant success in animal feed supplements, despite their low cost and disposal problems. A major disadvantage is their limited solubility, and the resultant instability of concentrates of the by-products. The invention comprises the treatment of the protein-rich by-products with a mild enzymatic treatment which stabilizes the by-products against protein gelation, and the thermal, and/or enzymatic treatment of the lactose-rich by-products to avoid separation of the lactose from concentrates.

  • Patent number: 5566086
    Abstract: A method is for expanding the solute-identifying capabilities of an infrared (IR) sparging system. In IR-sparging, bubbles transfer solutes contained in a volume of liquid to a gas stream which is analyzed in a gas cell. FTIR spectrometry provides spectral absorbance analysis to identify and measure the solutes. By repeating the spectral scans at given time intervals, data is also obtained which is related to the depletion rate curves of the respective solutes. Using this depletion rate data to complement the spectral analysis data provides major benefits in successfully identifying the solutes.
