Filed: 1999-06-03
Abstract: A snow removal device that picks up snow from the ground and flicks the snow into impeller units that transport the snow into a discharge tube whence the snow is expelled from the system. The system primarily includes a pick-up assembly, an impeller assembly, and a discharge tube. The pick-up assembly has a drum array that includes rows of triple-stepped blade-like fingers distributed evenly around each drum of the array of drums. These fingers are stiffly flexible and can cleanly and efficiently pick up snow from uneven ground surfaces and flick the snow into the impeller assembly that is mounted parallel to the axis of the drum array. The impeller assembly includes a plurality of impeller units that transport the snow into the discharge tube. The impeller units are reversible in direction, allowing the snow to be discharged to the right or the left of the system, or to the right and left simultaneously. The discharge tube and the impeller assembly lie in the same plane and are tilted upward approximately 20° relative to the ground. Thus, the snow is discharged at a relatively low height to the ground. The discharge tube and impeller assembly can be pivotally attached to the floating chassis, allowing the plane of the impeller assembly and the discharge tube to be tilted at a steeper angle relative to the ground. The snow removal device may be pulled or pushed by a prime mover and powered by an externally mounted hydraulic system.

Title: Triterpene saponin analogs having adjuvant and immunostimulatory activity
Inventor: MARCIANI DANTE J
IPC: C07H15/256
Filed: 1998-05-20
Abstract: The present invention is directed to novel chemical compounds in which a lipophilic moiety such as a lipid, fatty acid, polyethylene glycol or terpene is covalently attached to a non-acylated or desacylated triterpene saponin via a carboxyl group present on the 3-O-glucuronic acid of the triterpene saponin. The attachment of a lipophile moiety to the 3-O-glucuronic acid of a saponin such as Quillaja desacylsaponin, lucyoside P, or saponin from Gypsophila, Saponaria and Acanthophyllum enhances their adjuvant effects on humoral and cell mediated immunity. Additionally, the attachment of a lipophile moiety to the 3-O-glucuronic acid residue of non- or des-acylsaponin yields a saponin analog that is easier to purify, less toxic, chemically more stable, and possesses equal or better adjuvant properties than the original saponin.
