Title: Pharmaceutical hydrogel formulations, drug delivery devices and methods
Inventor: VENKATRAMAN SUBRAMANIAN S
IPC: A61K9/06
Filed: 1998-12-01
Abstract: Pharmaceutical hydrogel formulations containing polyvinyl alcohol are provided. The formulations may serve as drug reservoirs in electrotransport drug delivery systems (10) or passive transdermal systems, or they may be used in a variety of other types of dosage forms, e.g., capsules, suppositories, aerosols, and the like. With these formulations, there is virtually no syneresis encountered upon long term storage, an advantage that derives from selecting the quantity of polyvinyl alcohol in the gel to correspond to the polymer's degree of hydrolysis.

Title: Foam extrusion apparatus and method with viscosity controls
Inventor: SADINSKI ROBERT L
IPC: B29C48/07
Filed: 1998-12-17
Abstract: An extrusion system utilizes single (30) or tandem extruders (102 and 103) and a mixer-cooler (104) to extrude a foamable extrudate through a die (37) in a sealable chamber. The foamable extrudate is shaped and calibrated within the chamber (40). The product exits the chamber to atmosphere on a continuous basis through a submerged orifice in a water baffle immersion seal. The seal includes the submerged orifice with a free wheeling guiding system upstream of the orifice.  Immediately ahead of the guiding system, the parameters of the foam extrudate are sensed to control the configuration of the orifice on a continuous basis. Before the extrudate passes into the water baffle seal it moves over a floating dancer roll (65), the position of which controls a haul-off, such as a vacuum belt, at the tail end of the system. This avoids pushing on the extrudate.

Title: Method and apparatus for forming bends in thermoplastic pipe
Inventor: PERY-JOHNSTON RANALD JOHN
IPC: B29C53/08

Title: Novel ammonium octamolybdate composition and method for producing the same
Inventor: BRUHL TIMOTHY G
IPC: C01G39/00
Filed: 1999-06-08
Abstract: A novel isomer of ammonium octamolybdate ("AOM") and method for producing the same. A new AOM isomer("X-AOM") is described which is characterized by a distinctive Raman spectral profile compared with other AOM isomers including .alpha. and .beta. - AOM. Compared to .alpha.-AOM, X-AOM of the present invention offers improved smoke suppression characteristics and greater stability and uniformity. To produce the novel isomer, ammonium dimolybdate ("ADM") (12) is combined with molybdenum trioxide ("MoO3")(34) and water (14) to yield a mixture. When mixing these materials, optimum results are achieved if at least one of the foregoing molybdenum-containing reagents is added in a gradual, non-instantaneous manner so that the selected reagent is not added to the mixture in a single large mass. This gradual delivery procedure, along with a carefully controlled prolonged heating state (e.g. in excess of 3 hours) contributes to a maximum yield of high purity. The method of the present invention facilitates the generation of X-AOM in an effective and preferential manner on production-scale levels. Thus, the present invention addresses the disadvantages of the prior art by being capable of producing large quantities of high purity AOM.

The output period is tunable by adjusting t he phase delay of orthogonal polarization components. A contrast ratio of  20 d B can be realized. The device allows the mux/demux of up to 200 WDM channels with a 50 GHz frequency spacing. Applications of the device include a band splitter, a wavelength selective cross-connect, and a wavelength monitor.</S DOAB>
