Abstract: A spade blade drill having blended open notch forms on either side of an apex. The notches transition into elliptical flutes which extend outwardly toward sides of the insert. The elliptical flute profiles inhibit chip curling and packing. The sides incorporate a pair of surfaces having a reduced clearance angle for preventing chip packing. The blended open notches are deep and extend across the entire width of the flutes, enhancing heat transfer surface area and allowing chips to flow along the entire flute surfaces. A plurality of chip splatters extend from the flutes across two relief surfaces. The chip splatters have a rounded profile, inhibiting chips from becoming hung in the splatters.

Abstract: An assembly comprising a pump rod and a threaded union of easy assemblage and capable of transmitting high torque. The pump rod, having a hollow body, activates rotary-type pumps. The motion that activates the pump is, in this case, produced by rotary movement by means of the application of a rotation moment or torque. The type of rod presently used and that this invention replaces for use in rotary pumping is under the API 11B Norm. One distinctive characteristic is the type of special threaded union that is used for coupling of the different rods. This union includes a nipple or threaded member in its outside surface in its two extremes called male - that are coupled respectively with a pair of members, each one of them threaded in its internal surface - called female. The union between the male and the female extremes is accomplished by means of the threaded surface of such extremes. Other characteristic of the assembly hollow rod - threaded union is greater resistance to uncoupling by counterrotation turn of the column of rods or "backspin".

Les premiers et deuxièmes lots sont ensuite individuellement gazéifiés en vue de former un premier et un deuxième courants gazéifiés d'une première et d'une deuxième couleurs de densité et de propriétés rhéologiques sensiblement identiques. Après gazéification de la première et de la deuxième portions, les premiers et deuxièmes courants colorés sont envoyés dans un bloc collecteur à filière où ils sont extrudés en quantités disproportionnées pour former un cordon multicolore ayant les première et deuxième couleurs en proportion inégale. Un agent décollant à base d'amidon est appliqué et le cordon est découpé en pièces individuelles. Celles-ci sont ensuite séchées jusqu'à 1 à 5 % de teneur en eau. Le procédé est conçu de manière à prévoir deux, trois, quatre couleurs différentes ou davantage. Des guimauves multicolores (4-6/g) à multiples phases colorées disproportionnées peuvent être préparées. Ces guimauves peuvent être consommées sous forme de confiseries ou peuvent être ajoutées à des céréales prêtes à l'emploi pour petits déjeuners.

Title: Guidewire filter and methods of use
Inventor: TSUGITA ROSS
IPC: A61M25/09
Filed: 2000-11-15
Granted: 2008-12-02
Abstract: A filter system for temporary placement of a filter in an artery or vein is disclosed. The filter system includes a guidewire that is first positioned across a lesion within a vessel. The guidewire may include a distal stop. A slideable filter is then advanced along the guidewire using an advancing mechanism, typically an elongate member slideable over the guidewire and contacting the filter. A capture sheath may be disposed about the filter during advancement. Once the filter is positioned downstream of the lesion, the capture sheath is withdrawn, allowing the filter to expand.  Further distal advancement of the filter is prohibited by the stop. After expansion of the filter, the capture sheath and the advancing mechanism are withdrawn from the region of interest, and removed from the patient's vessel. The filter may then be retrieved using a capture sheath or exchanged for a second filter after removing the first filter.

Abstract: Une association de sécurité existante est ré-établie lorsqu'un événement de transfert intercellulaire de communication se produit dans un système de communications radio tel que IEEE 082.11 ou un réseau de zone locale radio à haute performance (HIPERLAN), l'association de sécurité existante entre un terminal mobile et un réseau de communication sans fil étant maintenue lorsque le transfert intercellulaire de communication se produit à l'intérieur du réseau. L'authentification pendant un événement de transfert est réalisée par une procédure de demande d'accès/réponse. Selon ladite procédure, chaque élément de deux communications qui est constitué d'un nouveau point d'accès et du terminal mobile expérimentant un transfert intercellulaire vers le nouveau point d'accès envoie une demande d'accès à l'autre élément des deux communications. Chaque élément des deux communications calcule alors une réponse à sa demande d'accès reçue et ces réponses sont renvoyées à l'autre élément des deux communications. Chaque élément des deux communications compare ensuite sa réponse reçue par rapport à une réponse correcte. Lorsque ces comparaisons sont correctes, une communication de charge utile commence entre le second point d'accès et le terminal mobile.
