Abstract: The invention concerns a method and a plant for regenerating lubricating waste oil with low content of fuel, fatty acids and chloric products. The lubricating waste oil is subjected to the following steps successively: adding strong bases in aqueous solution at the rate of 0.5 to 3 % of pure bases by mass of waste oil; dehydrating and extracting the light hydrocarbons, extracting and recuperating the gas oil (stripping); extracting the impurities. The invention is characterised in that a complementary addition of a strong base in aqueous solution at the rate of 0.1 to 1 % by mass of waste oil is carried out following the dehydrating and extracting of light hydrocarbons. The treated lubricating waste oil are rid of their impurities by distillation.

Title: Novel formulations of pharmacological agents, methods for the preparation thereof and methods for the use thereof
Inventor: DESAI NEIL P
IPC: A61K47/42
Filed: 1998-06-26
Granted: 2012-04-03
Abstract: In accordance with the present invention, there are provided compositions and methods useful for the in vivo delivery of substantially water insoluble pharmacologically active agents (such as the anticancer drug paclitaxel) in which the pharmacologically active agent is delivered in the form of suspended particles coated with protein (which acts as a stabilizing agent). In particular, protein and pharmacologically active agent in a biocompatible dispersing medium are subjected to high shear, in the absence of any conventional surfactants, and also in the absence of any polymeric core material for the particles. The procedure yields particles with a diameter of less than about 1 micron. The use of specific composition and preparation conditions (e.g., addition of a polar solvent to the organic phase), and careful selection of the proper organic phase and phase fraction, enables the reproducible production of unusually small nanoparticles of less than 200 nm diameter, which can be sterile-filtered. The particulate system produced according to the invention can be converted into a redispersible dry powder comprising nanoparticles of water-insoluble drug coated with a protein, and free protein to which molecules of the pharmacological agent are bound. This results in a unique delivery system, in which part of the pharmacologically active agent is readily bioavailable (in the form of molecules bound to the protein), and part of the agent is present within particles without any polymeric matrix therein.

Title: Stent for treating pathological body vessels
Inventor: STRECKER ERNST PETER
IPC: A61B17/12
Filed: 1998-01-24
Granted: 2007-04-17
Abstract: A known method for treating pathological body vessels is the implantation of stents (1) as an extended filament (2), by means of a catheter (22), which springs into a given form only once at the implantation site, as a result of its thermo-memory property or its elasticity. The invention relates to a new kind of stent (1), created in order to improve the flexibility and stability of the stent. This is achieved in that the stent filament or stent filaments (2, 2' ) are present in the form of at least two opposed spirals (3, 3'). The filament (2) consists of a material with high elasticity or with thermo-memory properties. The stent (1) can be covered with a structure made of pieces of fabric and/or fibres, and serves in this way as a stent graft. The new stent demonstrates high stability and flexibility. The stent can be introduced into a body vessel by means of a lumen, which essentially corresponds to the outside diameter of the filaments (2, 2 ') forming the stent (1), by means of catheter (22), and expands in the point of destination to a larg e- lumen tube-shaped implant.

Granted: 2004-01-27
Abstract: A broadband diffractive diffuser contains at least three levels, with approximately a phase shift of a between at least two of the at least three levels. Such a diffuser provides light with more than two phasor vectors at the zero order. The presence of the more than two phasor vectors reduces the zero order diffraction efficiency at non-design wavelength, increasing the usefulness of the diffuser at wavelengths other than the design wavelength. Preferably, the diffractive diffuser includes a plurality of regions, approximately 50 % of an area of the plurality of regions presenting a phase shift of .pi. at a design wavelength, approximately 25 % of the area of the plurality of regions presenting a phase shift of 2.pi. at the design wavelength, and approximately 25 % of the area of the plurality of regions presenting a phase shift of 0 at the design wavelength. Such a diffractive diffuser may be formed by logical operations between two diffractive diffuser patterns, by adding two diffractive diffuser patterns, or by pixel-by-pixel scanning.

Filed: 2000-02-09
Granted: 2009-05-05
Abstract: A seal (12) that is particularly suitable for use in a gas spring (and other high pressure hydraulic and pneumatic sealing applications) and that minimizes leakage of relatively high pressure gas and lubricating oil from the rod end of the gas spring.  The generally annular seal body (62) includes a radially inwardly dacing surface (64), force directing lobes (74, 76, 78, 82, 84) and either a plastic wiper insert or a wiper lobe (88) that are designed for minimizing the leakage of oil between the radially inwardly facing surface of the seal body and the adjacent, radially outwardly facing surface of the gas spring's piston rod, and that include a corner edge that projects radially inwardly beyond the plane of the seal body's radially inwardly facing surface. When the seal body is compressed for use in a gas spring and is thus subjected to the high-pressure gas, the induced stresses in the seal body result in the corner edge being forced against the adjacent surface of the piston rod to effectively prevent the leakage of oil therebetween. The permeation of gas axially through the seal body is minimized by the inclusion of a co-molded metal plate (106) in the seal body adjacent to the rod end of the seal body.
