  • Patent number: 5051262
    Abstract: Specifically, the present invention relates to processes for preparing delayed action galenic forms. The process is characterized in that the application solutions of excipients, coatings and active constituents are adjusted to a desired pH. The independence of the rate of dissolution of a controlled release or sustained action oral pharmaceutical form is increased by admixing a pH adjusting agent with every application solution of medicament, excipeint or coating, throughout the course of formulation of the pharmaceutical form.

  • Patent number: 4397570
    Abstract: A new and useful composition of matter, solid at room temperature, is disclosed, comprising: (1) an effective amount of a suitable nucleating agent substantially uniformly dispersed in (2) a suitable pressure-sensitive adhesive for encapsulating a temperature-sensitive solid mixture having a given nucleation efficiency and which melts at a predetermined temperature, whereby the suitable nucleating agent is (a) inert to both the pressure-sensitive adhesive and the temperature-sensitive solid mixture, and (b) capable of raising the nucleation efficiency of said solid mixture. The novel composition of matter overcomes the extreme super-cooling achieved by temperature-indicating compositions of matter in U.S. Pat. No. 4,232,552 (which change color with a change in phase) without the use of classical nucleating agents being employed in such temperature-indicating compositions of matter.

  • Patent number: 4371485
    Abstract: A new and useful hydrophilic polyester fiber and process of making same are disclosed; the fiber has a stable pore system exhibiting a moisture pickup (regain) of at least about 2 percent by weight at 40.degree. C. and a relative humidity of 92%. Our experiments indicate that the proportion of moisture regain is attributable to capillary condensation in an amount of at least 25%. The hydrophilic properties are the result of a certain pore system within the fiber which enables capilliary condensation to occur significantly. The invention describes one way to accomplish this, namely by the addition of a predetermined amount of a suitable oxalato-complex to a suitable polyester mass. Most preferably, about 10% by weight K.sub.3 Al(C.sub.2 O.sub.4).sub.3 is added to the polyester mass.

  • Patent number: RE34515
    Abstract: An improved steam sterilization indicator is provided. The indicator includes a fusible material in tablet form, deposited in an embossment in one end of a thin aluminum backing. A wicking strip is attached to the backing with one end of the strip being in close proximity to the fusible tablet. A clear plastic material covers the tablet and the strip and is adhered to the backing. The melting point of the fusible tablet is depressed in the presence of saturated steam. Upon melt, the material in the tablet is absorbed by the wicking strip, producing a color front to provide an indication of the integration of time and temperature in the presence of steam. Various amounts of a binder are used in the tablet to provide a device which may be adjusted to reflect the thermal death curves of various types of microorganisms. The cover and the wick are bonded to the backing by an acyclic adhesive which also affects the rate of the indicator.
