Abstract: A modular radius conveyor belt formed of rows of belt modules pivotally interlinked by transverse pivot rods and specially adapted for following a curved conveyor path. The modules include a top, product conveying surface and a bottom, sprocket-driven surface.      The belt modules have a plurality of first link ends disposed in the direction of travel of the conveyor belt and a plurality of second link ends disposed in the opposite direction. Transverse holes in the link ends are aligned to accommodate a pivot rod. When the link ends of the consecutive rows of side by side modules are intercalated, the pivot rod serves as a hinge pin in a hinged joint between consecutive interlinked rows. To permit the belt to flex side-wise, the openings in the first link ends are slotted longitudinally in the direction of belt travel. The link ends have leg portions with differing widths. The link ends having the transverse slots are wider than the link ends having the transverse openings such that the cross-sectional areas of the leg portions are approximately equal.

Abstract: The liner retainer assembly includes a cylinder that is mounted on a module of the fluid end of a pump. The cylinder has an aperture for receiving a liner and a retaining piston. A retaining nut is secured on the end of the retaining piston and engages one end of the liner. The retaining piston forms a fluid cavity and a spring cavity within the cylinder. The spring cavity houses a plurality of springs which bias the piston, retaining member, and liner towards the module, thus providing a resilient securing force. The fluid cavity communicates with a supply of hydraulic fluid for biasing the piston away from the module to relieve the springs. By pressurizing the fluid cavity, the springs are compressed to disengage the retaining member from the liner and allow th e unthreading of the retaining member and then the removal of the liner.

Title: Process of converting rendered triglyceride oil from marine sources into bland, stable oil
Inventor: MAG TED
IPC: A23K20/158
Filed: 2000-01-28
Granted: 2003-10-07
Abstract: Triglyceride oil derived from marine sources, mammalian and fish, is treated with a silica at relatively low temperature under vacuum and is then further treated with a bleaching clay under vacuum and at higher temperature. The silica and the bleaching clay are then separated from the oil. The oil treated by this method is essentially free of proteinaceous materials, phosphatides and mucilage, pro-oxidant metals and very low in colored compounds, and is suitable for deodorizing. The deodorized oil is completely bland, unchanged in the concentration of the long-chain highly unsaturated fatty acids (EPA, DPA and DHA), very low in color, peroxides and secondary oxidation products, free of pesticides and has very good flavor stability.        The method avoids the use of any chemicals, such as in the acid and base treatments required in conventional degumming and alkali refining of oils of marine origin. This avoids the formation of artifacts in the oil and trace contamination with chemicals. It also reduces the number of process steps required to produce deodorized food oil from marine sources, which is advantageous in respect to oil quality, process losses and processing costs. The method is especially environmentally advantageous, since it avoids the need for soapstock and waste water processing entirely.     Refined oil produced by the method is useful as a nutritional supplement and in methods of therapy or medical treatment.

Title: Soil-resistant coating for glass surfaces
Inventor: BOND BOB
IPC: C23C14/34
Filed: 1999-02-02
Granted: 2004-04-06
Abstract: A glass article which has a water-sheeting coating and a method of applying coatings to opposed sides of a substrate are described. In one embodiment, a water-sheeting coating (20) comprising silica is sputtered directly onto an exterior surface of the glass. The exterior face of this water-sheeting coating is substantially non-porous but has an irregular surface. This water-sheeting coating causes water applied to the coated surface to sheet making the glass article easier to clean and helping the glass stay clean longer. In one method of the invention, interior and exterior surfaces of a glass sheet are cleaned. Thereafter, the interior surface of the sheet of glass is coated with a reflective coating by sputtering, in sequence, at least one dielectric layer, at least one metal layer, and at least one dielectric layer. The exterior surface of the glass is coated with a water-sheeting coating by sputtering silica directly onto the exterior surface of the sheet of glass. If so desired, both the interior surface and the exterior surface can be applied during the same pass through the same sputter coating apparatus while the glass maintains a constant orientation wherein the interior surface is positioned above the exterior surface.

Abstract: L'invention concerne des dérivés d'acides uréidophénoxy-isobutyriques aryle et hétérocycliques et d'acides carboxamidophénoxy-isobutyriques aryle et hétérocycliques, qui inhibent la glycosylation non enzymatique de protéines entraînant souvent la formation de produits terminaux et de liaison croisée de glycosylation avancée. De nombreux autres dérivés d'acides phénoxy-isobutyriques ainsi que certains autres composés présentés dans l'invention inhibent également la glycosylation non enzymatique de protéines. La glycosylation non enzymatique et la liaison croisée de protéines font partie du processus de vieillissement, la glycosylation de produits terminaux et la liaison croisée de protéines à longue vie augmentant avec l'âge. Ce processus s'accroît à des concentrations sanguines élevées de sucres réducteurs et dans un environnement intracellulaire tel que celui du diabète. L'intégrité structurale et fonctionnelle des molécules touchées est perturbée par ces modifications et peut entraîner de graves conséquences. Les composés de l'invention peuvent être utilisés pour inhiber ce processus de glycosylation non enzymatique, et par conséquent pour inhiber certains effets pathologiques du diabète ou du vieillissement. Les composés sont également utiles pour prévenir un vieillissement prématuré et une détérioration de protéines alimentaires, et peuvent prévenir une décoloration des dents.
