Title: Method and apparatus for the multiple stage cementing of a casing string in a well
Inventor: BRANDELL JOHN T
IPC: E21B33/16
Filed: 1994-08-17
Abstract: ABSTRACT OF THE INVENTION The present invention provides a cementing tool  for cementing  multiple  stages  within  a  well.    The assembly includes  a  housing  assembly  which  defines  one  or  more cementing ports.  A first sleeve assembly is retained within the housing and is movable from a first position, where the sleeve covers the port,  and thereby precludes fluid flow therethrough, to a second position wherein the sleeve opens the cementing port.   The apparatus also includes a second sleeve assembly which is movable from a first position away from the cementing port to a second position wherein the sleeve  assembly covers  the  port.    The  first  sleeve  is cooperatively configured with the housing assembly to provide engaging surfaces which resist rotation of the first sleeve relative to the housing.  Additionally, the first sleeve and the second sleeve assembly are configured to limit relative rotation when the two pieces are longitudinally adjacent one another.

Inventor: NODA KAZUO
IPC: G11B7/131
Filed: 1995-08-15
Abstract: A laser light beam generated from a light source is divided by a diffraction grating into a plurality of light beams, i.e., a single main beam to be used for recording information and plural auxiliary beams distributed on two imaginary straight lines crossing each other.   One of the straight lines extends parallel to tracks of a recording medium.   The resultant divided beams are converged to be irradiated onto a recording medium, and reflected components, from the recording medium,  of the beams are received by corresponding light receiving elements.  Thus, the main and auxiliary beams distributed on one of the two imaginary straight lines are used to perform focusing and tracking.          Further, one of the two auxiliary beams distributed on the other straight line are used to determine whether a track where information is to be recorded is a blank area or not, and the other of the auxiliary beams is used to verify whether the information has been recorded correctly.

Title: Software architecture for providing communication features to different types of wireless telephones via different communication switching systems
Inventor: BALES BRUCE MERRILL
IPC: H04Q7/24
Filed: 1996-01-17
Abstract: A mobility management system and a traditional telecommunication switching system provide telecommunication terminal features by the mobility management system executing a software architecture that utilizes a unique terminal management application for each type of wireless terminal and a unique terminal emulator application for each type of telecommunication link that interconnects the mobility management system to the telecommunication switching system. There is an individually assigned telecommunication link for each wireless terminal. The terminal management applications and the terminal emulator applications communicate utilizing an internal message protocol. In response to a wireless terminal requesting actuation of a feature, a terminal management application converts that request into the required internal protocol messages and transmits the internal protocol messages to the terminal emulator application that controls the telecommunication link assigned to the wireless terminal. In response to the internal protocol messages, the terminal emulator application emulates the type of telecommunication terminal that normally would be connected to the assigned telecommunication link. The telecommunication switching system is responsive to the emulation to provided the requested feature as if telecommunication terminalwas connected to the assigned link. The responses of the telecommunication switching system received via the assigned telecommunication link are converted to internal protocol messages and transmitted back to the terminal management application. The terminal management application converts and transmits the responses to the wireless terminal. The same internal protocol messages are used to invoke a particular feature regardless of the telecommunication terminal type ortelecommunication link type.
