Title: Razor frame with integral weight
Inventor: FOLLO THOMAS A
IPC: B26B21/52
Filed: 1999-03-30
Abstract: The present invention is directed to a razor unit having a member comprising a top frame with an integral weight.

Title: Methods for drug target screening
Inventor: HARTWELL LELAND
IPC: C12Q1/68
Filed: 1998-02-27
Abstract: The present invention provides methods for identifying targets of a drug in a cell by comparing (i) the effects of the drug on a wild-type cell, (ii) the effects on a wild-type cell of modifications to a putative target of the drug, and (iii) the effects of the drug on a wild-type cell which has had the putative target modified of the drug. In various embodiments, the effects on the cell can be determined by measuring gene expression, protein abundances, protein activities, or a combination of such measurements. In various embodiments, modifications to a putative target in the cell can be made by modifications to the genes encoding the target, modifications to abundances of RNAs encoding the target, modifications to abundances of target proteins, or modifications to activities of the target proteins.

Abstract: L'invention concerne des distributeurs (20) pour liquides, qui comportent un orifice distributeur latéral et dans lesquels le liquide est stocké dans le corps principal (26) d'un récipient (22) élastiquement déformable, couplé à une structure goulot (30) qui présente un orifice de sortie inférieur (42) disposé à l'intérieur d'une structure de base (24). En utilisation, on soulève le distributeur (20) puis on l'incline de 30 à 50· avant de presser le récipient. L'inclinaison du distributeur fait qu'une partie de l'air contenu dans la structure de base (24) est piégé, ce qui minimise l'effet de la compensation thermique sur la vitesse de réaction. Ceci permet de presser immédiatement le récipient afin de forcer le liquide à traverser la structure de base (24) et à sortir par l'orifice distributeur latéral. L'invention peut se présenter sous diverses formes, de façon à s'adapter à des liquides ayant des propriétés différentes.
