  • Portable flexible and extendable drain pipe
    Publication number: 20070051417
    Abstract: A flexible collapsible corrugated drain pipe has a corrugation structure that permits a tight bending radius and relatively facile collapsing and expansion of corrugations, thereby permitting convenient manipulation and installation of drain pipe and packaging, display, storage and transportation of the collapsed pipe sections.

  • Method for recovering indicine-N-oxide
    Patent number: 4458082
    Abstract: An improved process for recovering Indicine-N-oxide from plant sources which involves water extracting the plant material, preferably by water buffered at pH 7, followed by adsorbing the Indicine-N-oxide from the extract, after which the Indicine-N-oxide is eluted from the adsorbent in alcoholic solution, then concentrated and purified as heretofore.Desirably, the adsorbed Indicine-N-oxide is water washed prior to elution so as to remove any water soluble impurities that had been adsorbed from the extract.A preferred adsorbent is a cross linked polystyrene.

  • Injection molding control method
    Patent number: 4066725
    Abstract: The control cycle for an injection molding machine comprises successive fill, compaction, hold, cure and mold open times. The ram position and mold pressure are monitored at predetermined times respectively after the molding cycle has begun. If the ram position is out of tolerance, the fill pressure is adjusted to compensate for the deviation. If the mold pressure is out of tolerance, the compaction pressure is adjusted to compensate for the deviation in mold pressure.

  • Stabilization of internally administered pancreatic lipase
    Patent number: 3991180
    Abstract: A method for treating exocrine pancreatic insufficiency is disclosed. The method comprises the administration of a stable solid medicinal preparation containing finely particulated lipase intimately admixed with Hammarsten's casein and a tabletting lubricant, whereby a hydraulic pressure of about 2000 to about 5000 psi is employed.

  • Injection molding control
    Patent number: 3932083
    Abstract: The control system for an injection molding machine providing successive fill, compaction, hold, cure and mold open times. The ram position and mold pressure are monitored at predetermined times respectively after the molding cycle has begun. If the ram position is out of tolerance, the fill pressure is adjusted to compensate for the deviation. If the mold pressure is out of tolerance, the compaction pressure is adjusted to compensate for the deviation in mold pressure.
