  • Patent number: 11497712
    Abstract: The present disclosure provides a method of preparing a pharmaceutical composition. The method includes transferring a predetermined quantity of an excipient mixture from a second vessel to a first vessel. The excipient mixture transferred from the second vessel includes a liquid-state second quantity of a hydrofluoroalkane propellant and a first solubilized excipient comprising a low-molecular weight poly(ethylene oxide) polymer. The method further includes contacting at least one pharmaceutically-active compound with the excipient mixture under conditions that facilitate forming an intermixture comprising the propellant, the polymer, and the compound. Before transferring the excipient mixture, the first vessel contains a vapor-phase first quantity of the hydrofluoroalkane propellant and an effective amount of the at least one pharmaceutically-active compound.

  • Patent number: 7687054
    Abstract: Methods, compounds, and medicinal formulations utilizing biocompatible polymers for delivery of a drug, particularly for solubilizing, stabilizing and/or providing sustained release of drug from topical, implantable, and inhalation systems. Many of the methods, compounds, and medicinal formulations are particularly suitable for oral and/or nasal inhalation and use polymers of the formula —[X—R1—C(O)]— wherein each R1 is an independently selected organic group that links the —X— group to the carbonyl group, and each X is independently oxygen, sulfur, or catenary nitrogen.

  • Patent number: 6313433
    Abstract: A computer controlled laser material processing system has a plurality of laser sources the beams of which are selectively operable between two modes. In a first raster engraving mode the beams are separated and independently controllable in synchronism with the motions of a beam delivery system to form plural, parallel, spaced apart scan lines on the surface of the workpiece for affecting the surface at high speed. In a second vector cutting mode the beams are combined such that they are collinear and have a power approximately equal to the sum of the powers of each individual laser source for cutting the surface at high power.

  • Patent number: 6181719
    Abstract: A gas laser RF power supply has two RF oscillators operating at different frequencies, the first frequency to provide maximum RF voltage to the plasma tube prior to ignition, and the second frequency to provide optimum power for sustaining CW or pulse operation of the laser. The oscillator outputs are modulated to control power to the tube, the one in the form of RF pulses at the first frequency and at a power level below the laser emission threshold, and the other in CW or pulse form at the second frequency at a laser gas medium excitation level above the laser emission threshold. The first frequency is the resonance frequency of the tube prior to plasma ignition and the frequency of minimum average RF power required for a reliable ignition. The second frequency is the most efficient operating frequency for the plasma ignited and kept ionized by the pulses of the first frequency and provides maximum output laser power.
