Inventor: MCDONALD CLAYTON
IPC: B61B10/04
Filed: 1999-04-08
Abstract: A shock absorber trolley has a trolley frame including trolley wheels, a rearward cam, and a shock absorbing mechanism linked to the rearward cam. The trolley is especially adapted for use in a trolley assembly employed for bias banking of assembly loads. The chock absorbing mechanism decelerates an adjacent trolley assembly during accumulation by absorbing impact energy when the leading trolley of the adjacent trolley assembly strikes the rearward cam of the shock absorber trolley. When employed as an intermediate trolley in a trolley assembly, the absorption of energy minimizes both noise generation and swaying of the assembly load during the biased banking of loads.

Title: Transmucosal induction of tolerance to parenterally administered non-autologous polypeptides
Inventor: RUDNIC EDWARD M
IPC: A61K38/17
Filed: 1998-03-19
Abstract: Disclosed is a method for reducing an immune response to a parenterally administered non-autologous antigen in an individual who is immunologically responsive thereto by mucosally administering to the individual an amount of the antigen effective to reduce any immune response to parenteral administration of said antigen. The antigen can be a polypeptide such as a hormone, like insulin, which supplements a metabolic deficiency in the recipient of a polypeptide intended to serve the same function. The polypeptide can also be one which supplements a deficiency in the production of a physiologically important polypeptide, such as a hematologic regulatory factor. The hematologic regulatory factor can enhance or inhibit thrombogenesis or platelet deposition. Also, the antigen can be a tissue or cell preparation, such as of allogeneic or xenogeneic tissue or cells. The method for reducing an immune response is preferably one which induces tolerance to parenteral administration of the antigen, such as by inducing or elevating a suppressor T cell response to the mucosally administered antigen.
