Title: Reticulation de longueur nulle (sans lieur) de proteines et de composes lies
Inventor: KAPLAN HARVEY
IPC: C07K1/107
Filed: 2002-08-19
Abstract: La présente invention concerne une technique de réticulation de composés poly(amino acide) (par exemple des protéines, des polypeptides, des polymères protéiniques, etc.) entre eux ou de liaison de ces composés à des composés polyamino ou polycarboxyle. Cette technique consiste à lyophiliser une solution d'au moins un composé poly(amino acide), ou d'au moins un composé poly(amino acide) et d'un composé polyamino ou polycarboxyle, à maintenir ce solide lyophilisé sous vide, à chauffer ce solide lyophilisé sous vide à une température élevée efficace pour entraîner une réticulation sans dénaturer les composés poly(amino acide), à refroidir ce produit et à rétablir la pression atmosphérique. Cette technique produit une réticulation sans qu'il soit nécessaire de recourir à des composés activateurs ou à des molécules de réticulation. Cette invention concerne aussi de nouveaux produits réticulés.

Title: Noise suppressing flexible exhaust coupling
Inventor: HOUBE ALLEN G
IPC: F16L27/111
Filed: 1990-06-29
Abstract: Abstract of the Disclosure A coupling unit mountable in the exhaust train of an engine immediately downstream of the exhaust manifold provides a significant reduction in engine noise levels. The coupling unit does not include a rigid liner but comprises a flexible tubular coupling consisting essentially of inlet and outlet collar portions and an intermediate dual wrapped flexible central conduit portion.  The flexible dual wrapped central portion consists of a longitudinally undulating, pressure-carrying conduit member and a concentric, vibration-dampening helicoidal covering.  The flexible coupling has a length to inside diameter ratio in the range of 1:1 to 8:1, and permits limited multi-axis movement of one of the collar portions relative to the other.  The flexible metal coupling is effective in reducing noise levels at engine speeds in the range of from idle speed up to about 5,000 rpm.
