Abstract: A variable speed direct drive drill press/router is disclosed. The drill press/router includes a housing supported above a horizontal bed which contains a generally vertically extending spindle that is rotatably mounted within and partially extends below the housing. A manually engageable or motor driven driver axially moves the spindle predetermined distances toward and away from the horizontal bed. For driving the spindle, a switched reluctance motor is mounted at the upper end of the housing for rotary driving engagement at a desired range of predetermined speeds throughout the entire range of axial movement of the spindle. The lower end of the spindle is capable of interchangeably receiving a workpiece rotating tool such as a drill or router for drilling or routing a workpiece.

Abstract: 2149028 9410953 PCTABS00032 A method for the manufacturing of an absorbent structure in an absorbent article, such as a sanitary napkin, tampon, panty protector, wound or sore dressing and like articles is produced by using absorbent material in roll form directly in the product without first defibrating the material and then forming a mat. The material possesses good dispersion properties and swelling properties, , which are meaningful to the function of the product. A high surface dryness is obtained, among other things. In addition to cellulose fibres, the absorbent structure may also include superabsorbent material and/or binding fibres, among other ingredients. The pulp mat is very thin, therewith obviating the need to compress the mat further in the product. In the case of certain product applications, the material is softened mechanically prior to its use as an absorbent material.

Abstract: A circuit configuration in a multimedia network simulates an actual meeting room where the conferences between two or more people may be held. This facilitates the creation in the network of flexible, long-term multimedia conferences between conferees who are separated from one another. Any number of conferees may communicate with one another via one or more of audio, video, and data.      Virtual meeting rooms may persist in the network for predetermined periods of time controlled by the users of the meeting room. The room may remain in the network independent of whether or not a user is connected to the room. The meeting room is a vehicle whereby the activity of various media servers coordinated to effectuate conferences between multiple participants in more than one medium. The servers are associated with storage devices which may record or store certain aspects of multimedia conferences using the virtual meeting room.

Abstract: Appareil (10) et procédé de détection de fuites dues aux variations de la charge créée par le traitement d'un tissu ou aux transitions au début ou à la fin d'une intervention électrochirurgicale. Des électrodes active et de retour (11 et 16) entre un malade et une unité électrochirurgicale (13) sont parcourues par l'énergie RF détectée par des transformateurs inductifs (17 et 19). Un circuit mesure les fuites plus de deux mille fois par seconde. Cette fréquence est asservie au déphasage (23) entre la tension et le courant. Un logiciel et une boucle d'asservissement (26) gèrent la tension efficace afin de réduire la tension de crête de l'onde de sortie ou d'augmenter le facteur de crête par modulation de la largeur d'impulsions de l'excitateur RF. On mesure les variations du déphasage (23) des signaux (18 et 20) de courant actif et de retour ainsi que la tension et le courant de crête. On compare l'angle de phase  theta  avec un seuil et, s'il le dépasse, on augmente la fréquence à laquelle sont examinées les différences (22) entre les signaux (18 et 20) de courant actif et de retour. On examine les différences (22) entre les signaux (18 et 20) de courant actif et de retour et, si elles dépassent une valeur maximale de fuites lorsque le mode sélectionné est en coagulation, alors on réduit la largeur d'impulsions de l'excitateur RF afin de maintenir à une valeur constante les crêtes des formes d'onde de tension, tout en réduisant la tension efficace afin de ramener les fuites à une valeur maximale. Sinon, on maintient à une valeur maximale la fréquence à laquelle est calculé le courant de fuite, jusqu'à ce que l'angle de phase  theta  soit inférieur au seuil. Au cas où la différence (22) serait supérieure à une valeur maximale de fuites lorsque le mode est coupé ou bipolaire, on ramène la tension efficace à un niveau maximal. Sinon, le niveau demeure élevé jusqu'à ce que l'angle de phase  theta  soit inférieur à un seuil. On augmente le facteur de crête en réduisant le facteur de charge ou la largeur d'impulsions de la forme de l'onde de sortie.

Abstract: The item that is in consistent use everybay living is the tabie. At home, school, and at work, tables are nasessary part of our work and leiure time. Hance, variety of tables and desks are available in the market. The area under the table is perhaps the most difficult place to clea and to reach. In order to clean the area under the tables and desks, one must bend down to look for the mess and bend once again to reach the area. When using vacuums and such, the legs of the tables hinder the process. If the area around the tables and desks are free of obstruction., the cleaning process is made simpler. but with limited space in some areas, cleaning can be laborious. with these problems in mind, this new inventive table will enhance daily usage and reduce the amount of time and labor spent on cleaning. The said invention is a table that is collapsible, foldable and attachable to ahy walls, allowing greater usage of limited space in any rooms.

Title: Milling method for liners extending into deviated wellbores
Inventor: DAVIS JOHN P
IPC: E21B7/06
Filed: 1996-07-11
Abstract: An apparatus and method of milling a liner extending from a deviated wellbore into a main wellbore is disclosed. The liner is inserted through a window and cemented in place with the cement extending back into the main wellbore.  Mechanisms are provided on the liner to keep it away from the main wellbore casing wall to facilitate the proper operation of the washover tool. A top end taper is provided to help the washover tool reorient over the tubular liner if milling requires more than one trip into the well. A diverter is insertable prior to installation of the liner to assist in getting the liner to extend through a window. Upon milling through the liner, the washover tool straddles the diverter and latches into it to facilitate not only the removal of the diverter but also the entrapment of any debris created by the milling operation. Suitable sealing is provided with the diverter to keep the cement away from the latching mechanism during the cementing operation.
