Patent CA-2196961-C (CA)
Inventor: PALLMANN WILHELM
IPC: B24B3/36
Filed: 1997-02-06
Granted: 2001-05-08
Abstract: The  invention  relates  to  the  resharpening  of two-dimensionally acting knife sets in knife rims as they are used for the industrial production of wood flakes  from long logs and wood cut to length. Each knife set consists of a knife plate provided with a cutting edge and of several scoring organs whose scoring blades are tightly linked to the knife plate  according to the  invention.          After having advanced all knife sets their resharpening is done in a first phase by means of a grinding drum provided with ring grooves while the knife rim is rotating slowly.          In a second grinding phase the cutting edges are touched by  the  grinding  drum  which  moves  slightly  in  axial direction and for that purpose the knife rim is arrested intermittently. During this phase the residues remaining on the cutting edges and at the scoring organs in the area of the ring grooves are ground off.          Due to the present invention it is possible to resharpen the knife rims  inside of  the flaker via an automatic programmed control without loss of production and without the  assistance  of  maintenance  personnel  so  that  the flaking operation is not interrupted and the knife sets are always perfectly sharp.

Title: Axial ejection in a multipole mass spectrometer
Inventor: HAGER JAMES W
IPC: H01J49/42
Filed: 1998-06-02
Granted: 2004-04-06
Abstract: A method of operating a mass spectrometer having an elongated multipole rod set, in which a two dimensional RF field radially contains trapped ions in a mass to charge range of interest, and in which the ions are contained axially by a barrier field on an end lens and to which a low voltage DC is applied. Trapped ions are axially mass selectively ejected by taking advantage of the mixing of the degrees of freedom induced by the fringing fields and other anti-harmonicities in the vicinity of the end lens. Thus, ions can be mass selectively ejected at the exit end at the same time as ions are being admitted into the entrance end of the rod set, thereby taking better advantage of the ion flux from a continuous ion source. The axial mass selective ejection is performed by applying an auxiliary AC voltage to the end lens, or to the rods themselves, or both, and by scanning either the auxiliary AC voltage or the RF voltage on the rod set. Trapped ions can be concentrated near the exit lens by applying an axial field in the direction of the lens, or can be depleted by applying the axial field in the opposite direction. The axial field can be oscillated to dissociate trapped ions.

Abstract: Médicaments visant les anomalies du comportement alimentaire liées à l'anorexie mentale. Bien qu'il soit devenu habituel d'utiliser des tranquillisants, etc., pour traiter les symptômes psychiques propres à l'anorexie mentale caractérisée par des anomalies du comportement alimentaire, telles que le refus des aliments, les vomissements provoqués et le fait de manger en cachette, les résultats obtenus sont médiocres. L'administration des médicaments ci-dessus, c'est-à-dire de préparations à base d'hormone somatotrope humaine, permet de rendre l'envie de manger spontanée aux sujets qui ne pouvaient être nourris que par des moyens passifs, tels qu'éducation alimentaire forcée ou alimentation par sonde nasale. Ces médicaments sont particulièrement efficaces contre les troubles du comportement alimentaire de l'anorexie mentale basée apparemment sur une hyperactivité au niveau du système central de sécrétion du facteur de libération de l'hormone somatotrope (GH-RF).

Abstract: The fluid absorbent members according to the present invention preferably comprise three basic components: chemically stiffened, twisted, and curled bulking fibers, high surface area fibers, and a binder additive such as thermoplastic fibrous material or chemical binders. Fluid absorbent members according to the present invention use a high surface fiber and refining to provide capillary pressure (or suction) to the fluid absorbent member. These high surface area fibers are generally small and highly conformable. They provide the substrate with capillary pressure well in excess of the capillary pressure found in the bulk-providing chemically stiffened, twisted, and curled fibers (unrefined) alone. A presently preferred fiber for this high surface application is the eucalyptus family of wood pulp fibers. Eucalyptus provides desirable capillary pressure characteristics in combination with the chemically stiffened, twisted, and curled fibers and will not easily pass through a forming screen. In accordance with the present invention, these component materials are combined into a stratified, multi-functional fluid absorbent member wherein the strata are preferably co-formed. The present invention therefore provides structures wherein the properties of the strata may be tailored to suit particular applications by utilizing the different compositions of the strata to achieve specific functionality.
