Title: Well maintenance equipment and procedure
Inventor: MANSUY NEIL
IPC: E21B37/00
Filed: 2000-06-20
Abstract: The present invention relates to a method of removing deposits from various types of wells (17) including environmental recovery, water supply, horizontal, barrier, injection, recharge, and/or disposal wells (17). The method includes equipping a well (17) with an automated energy delivering system that is attached to the well (17). The energy delivering system is used to clean the surface of the well (17) and aquifer by supplying various types of energy to the well (17) and aquifer via injection lines (5, 6, 8, 11 and 12) and an eductor pipe (10). A pump (14) is used to pump the energy through flow valves (20 and 21) and injection lines {5, 6, 8, 11 and 12) and into the well (17). The energy that is supplied to the well (17) mobilizes any deposits in the well (17) and aquifer and cause them to flow into and up the wellbore thereby cleaning the well (17) and aquifer.

Abstract: A dynamic collaborative-browsing system (100) enables client programs (105a-d) connected to a computer network (120) to join and leave groups or sessions, to collaboratively browse together as a session, to communicate with other client programs (105a-d) in the session. Each client program in the session may act as a session leader, or may just follow a session leader as it browses network sites of the computer network (120). The system (100) includes client programs, executing on client computers, server software and one or more main servers. The main server (115) groups into server-defined cells. One or more client programs interact with the server software to cause the server (110a-d) to create a session, to cause the client program to connect to a network site, to notify the server software of the network site's location or URL, and to notify other client programs in the session of the network site's location or URL so that other client programs in the session become connected to the same network site. The server software facilitates the formation of client programs into sessions and allows the client programs to communicate, to connect to and view a same network site, and to perform other collaborative activities. The server software also groups sessions currently connected to network sites in a same cell, and notifies each session and the client programs of the sessions of all of the other sessions and client programs in the same cell. The server software also facilitates communication between the sessions and client programs connected to network sites in the same cell.

Abstract: The invention is a power converter having a transformer (T) with a primary side winding (T1A) and a secondary side winding (T1C). Both the primary side and the secondary side have switches (Q1 & Q101) which are switched on and off alternately. When the primary master switch (Q1) is switched on, the transformer (T) charges. When the primary master switch (Q1) is switched off, the intrinsic capacitance of the secondary slave switch (Q101) discharges generating the zero voltage switching condition for the secondary slave switch (Q101). The secondary slave switch (Q101) is switched on at a time determined in accordance with the waveform generated by the transformer (T). When the secondary slave switch (Q101) is switched on, the transformer (T) discharges and ultimately the charge from an output capacitor (C101) flows into the transformer (T) as a backflow which charges the transformer (T). The secondary slave switch (Q101) is switched off at a time determined in accordance with a current flowing through said secondary switch (Q101). The intrinsic capacitance of primary master switch (Q1) discharges generating the zero voltage switching condition primary master switch (Q1) is then switched on and the cycle repeats.

Title: Method and apparatus for reducing femoral fractures
Inventor: MILLER RICK
IPC: A61B17/16
Filed: 2003-10-08
Abstract: An improved method and apparatus for reducing a hip fracture utilizing a minimally invasive procedure which does not require incision of the quadriceps. A  femoral implant in accordance with the present invention achieves intramedullary fixation as well as fixation into the femoral head to allow for the compression needed for a femoral fracture to heal. To position the femoral implant of the present invention, an incision is made along the greater trochanter. Because the greater trochanter is not circumferentially covered with muscles, the incision can be made and the wound developed through the skin and fascia to expose the greater trochanter, without incising muscle, including, e.g., the quadriceps.  After exposing the greater trochanter, novel instruments of the present invention are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur. After preparation of the femoral cavity, a femoral implant in accordance with the present invention is inserted into the aforementioned cavity in the femur. The femoral implant is thereafter secured in the femur, with portions of the implant extending into and being secured within the femoral head and portions of the implant extending into and being secured within the femoral shaft.
