Title: Composition and methods for transdermal delivery of acid-labile drugs
Inventor: LI CHENSHENG
IPC: A61K47/18
Filed: 1996-01-11
Abstract: A transdermal penetration-enhancing, drug acid-lability reducing composition and related method are described. Specifically, the transdermal composition comprises: (a) a therapeutically effective amount of a pharmacologically active drug which is subject to acid catalyzed degradation; (b) a pharmaceutically acceptable carrier substantially free of a lower alkanol; and (c) a penetration-enhancing amount of a functional derivative of a fatty acid. Such compositions increase the usefulness of transdermal compositions that rely upon an organic acid such as oleic acid penetration enhancer.

Title: Mooring bed assessment apparatus and method
Inventor: BRUCE PETER
IPC: G01L5/00
Filed: 1996-04-26
Abstract: Apparatus is provided for producing measurement data capable of characterising a burial trajectory (2) traced out in a sea-bed soil (3), and additionally to be capable of measuring a soils parameter such as the penetration resistance of the soil (3). In particular the apparatus checks for the anchorability of a particular sea-bed location and also provides a certain indication of the nature of the soil in stratae in the bed at this location. Specifically the apparatus achieves measurements via a point on a burying apparatus (5) as the burying apparatus moves in the trajectory. More especially the apparatus includes means (19, 29) located in a body (12) carried by the burying apparatus to sense the distance along the trajectory (2) separating two spaced points on the trajectory, and from that by additional means sense the position of a point in the soil at a particular instant thereby enabling the path of the trajectory (2) to be plotted. These additional means can comprise for example an inclinometer (28) indicating the angle of the body (12) at a particular instant. The body (12) can further include a penetrometer (17) to measure soil resistance.

Title: On board lubrication systems for lubricating top of rail for cars and rail gage side/wheel flange for locomotives
Inventor: KUMAR SUDHIR
IPC: B61K3/02
Filed: 1998-04-23
Abstract: In railroad applications, a new method of simultaneously lubricating the rail gage side (RAGS) and wheel flanges ahead of a locomotive's tractive wheels and lubricating the top of the rail (TOR) behind the tractive wheels to reduce the resistance of the trailing cars and reduce the locomotive wheel flange wear. The method involves controlling both lubricating units with the same computer controller when a single locomotive is used and two controllers located in two different locomotives in the case of a locomotive consist. The rail gage side lubricant spray is applied on curves of 2 degrees or more only on the high rail. For the top of rail lubrication at the trailing end of the locomotive or locomotive consist this invention requires that the angle of the lubricant jet on the rail from the vertical be between 0 and 80 degrees from the vertical, with the angle increasing in the rear or trailing direction. It further requires that the lubricant jet be a solid jet without breaking into a spray cone.

Inventor: KRAUSE EDWARD A
IPC: H04N21/434
Filed: 1996-11-08
Abstract: A method and apparatus for multiplexing several encoded program streams into a single multiplex suitable for transmission over a data channel, the streams typically including video and audio. According to one embodiment of the invention, high data channel utilization is achieved by determining the order of sending data packets of program streams into the data channel. According to this embodiment, whenever data is to be sent into the data channel, a determination is made of which packet to send or append to the multiplex, said determination by selecting a channel that has a decoder buffer that is not approaching a full state, and said next packet is appended to said multiplex. The method further includes selecting a channel that substantially balances the decoder buffers of the decoders with which the program streams are decodeable.

Filed: 1997-02-20
Abstract: The present invention is a method to remove arsenic from arsenic-containing materials (10) which is roasted (14) to form an offgas (18) and a roasted arsenic-containing material (22). An oxygen containing gas (26) is contacted with the arsenic-containing material. The offgas is subjected to solids collection (30) to form solids (34) and an offgas (38) for scrubbing (42). The solids (34) are combined with the roasted arsenic-containing material (22) before solubilization (46). The offgas (38) is subjected to scrubbing (42) with a scrubbing solution (50) to form a scrubbed offgas (58). The scrubbing solution is a portion of a pregnant leach solution (54). The scrubbed offgas is treated to remove sulfur dioxide (62). During solubilization arsenic oxides, ferric sulfates and ferric arsenates are dissolved to form a product slurry (62). The product slurry is subjected to liquid/solid separation (66) to form a leach residue (70) and a pregnant leach solution (54). A portion of a treated solution (74) is combined with water (118) to form a wash solution (78). The wash solution is used during liquid/solid phase separation to wash the leach residue to remove arsenic.
