Abstract: L'invention concerne des composants magnétiques doux près de la cote désirée que l'on peut produire par des techniques de métallurgie des poudres à partir de compositions de poudre de fer et de lubrifiant. Les composants résultants présentent des propriétés magnétiques et thermiques isotropes, et on peut leur conférer des formes géométriques complexes par des techniques de compression classiques. On mélange à un lubrifiant une poudre ferromagnétique non revêtue, que l'on comprime. Après compression, les composants sont thermiquement traités à une température modérée de façon à épuiser le lubrifiant et, éventuellement, atténuer les contraintes induites pendant le pressage et réduire les pertes par hystérésis. En fonction de l'application, on peut individualiser les propriétés du matériau en faisant varier le contenu et le type du lubrifiant ainsi que les conditions de traitement thermique.

Abstract: An isolated microorganism comprising a Propionibacteria strain. When the microorganism is fed to ruminant, protein and fat levels in milk produced by the ruminant are increased, while body condition and milk production levels are maintained. When fed to the ruminant, the microorganism also has positive effects on various metabolic hormones and metabolites, e.g., an increase in energy balance, plasma non-esterified fatty acids levels, and plasma leptin level. Supplementation with propionibacteria reduced dry matter intake but did not affect milk production in the cows. Therefore, the propionibacteria of the invention made the cows more energy efficient as cows produced the same amount of milk, yet consumed less dry matter.

Title: Disposable syringe with a retractable needle
Inventor: SHUE MING-JENG
IPC: A61M5/32
Filed: 2004-10-29
Abstract: A disposable syringe includes a tubular needle seat inserted into a barrel for fixing a needle cannula. The needle seat has an axially extending cavity with a radially yieldable catch disposed therein. A plunger is movable in the barrel, and has an engaging head defining a rearwardly facing shoulder wall which is retained by the catch when the engaging head is extended into the cavity by a pushing force applied to the plunger.       The barrel defines friction diminishing regions such that when the needle seat is moved past the friction diminishing regions to be placed to a disposal position, friction between the needle seat and the barrel is diminished, thereby facilitating a subsequent pulling action of the plunger for retracting the needle cannula into the barrel.
