  • Patent number: 5863979
    Abstract: A method of making paper in which dry chemical additives are incorporated into the pulp mixture by addition of an entire bag containing the additive directly to the mixture, the improvement being that the bag is sealed with an adhesive closure, the adhesive being a hot melt consisting essentially of a water dispersable polyamide prepared from a diacid component comprising in major portion an aliphatic diacid of 6 or fewer carbon atoms and a diamine component consisting of one or more compounds of the formula :H.sub.2 N--C.sub.y H.sub.2y --(OC.sub.2 H.sub.4).sub.x --O--C.sub.y H.sub.2y --NH.sub.2where y is 2 or 3 and x is 1-50 and a wax. Such bags will not leak in shipping and handling, and yet can be added directly to paper batches at ambient temperature in the manner of the unsealable bags employed in the prior art.

  • Patent number: 5854379
    Abstract: A low-cost thermal decomposition degreasing method capable of drastically reducing the time required for a degreasing process which involves heating, vaporization and thermal decomposition, while assuring the shape retention property of an injection molded product during degreasing. The degreasing process comprises: (i) a first step wherein a molded product placed under a reduced pressure less than or equal to atmospheric pressure is heated at a temperature lower than the melting point of a thermoplastic binder so that the thermoplastic binder partially evaporates by 5 wt % or more, and then the molded product is further heated at a temperature lower than higher one of the melting points of a more volatile organic compound and a thermoplastic resin whereby the thermoplastic binder further evaporates by 10 wt % or more, and wherein the final temperature is set to 200.degree. C.

  • Patent number: 5527843
    Abstract: A blood separating composition for use in blood collection tubes, the composition having an absolute viscosity of 100,000-320,000 cP at 25.degree. C. at a shear rate of 1 sec.sup.-1 when the blood separating composition turns into its dynamic state from its stationary state, with a reduced viscosity of 50,000 cP or more at a shear rate of 10 sec.sup.-1 in the dynamic state. The absolute viscosity of said composition is 100,000-300,000 cP at the shear rate of 1 sec.sup.-1 when returning to the stationary state. Such a viscosity renders stable and less flowable and blood separating composition during storage, allowing it to form a stable partition barrier in each collection tube when centrifuged to separate the blood phases one from another, with the blood cells above the barrier being prevented from remaining within the serum. The blood separating composition does not release any harmful oily substance or the like.
