Title: Conductor Holding Device
Inventor: RINDERER ERIC R
IPC: F16L3/24
Filed: 1995-06-01
Abstract: A device adapted to be mounted on a wall stud for holding a conductor in a substantially fixed position extending generally parallel to the wall stud. The device comprises a bracket having an arm with at least one opening therein. The bracket is adapted to be mounted on the wall stud so that the arm extends laterally from the stud at one side of the stud. The device further comprises a clamp having a head and at least one leg projecting from the head adapted for reception in the opening in the arm. The leg of the clamp is movable in the opening in an axial direction with respect to the leg so that the head of the clamp can be pushed closer to the arm to move the clamp to a clamping position in which the head of the claim is in clamping engagement with a conductor disposed between the head and the arm and extending generally parallel to the wall stud. The device also comprises a retainer for retaining the clamp in the clamping position. The retainer comprises a structure on the arm adjacent the opening in the arm for biting into the leg of the clamp when the clamp is pushed to its clamping position thereby to lock the clamp in its clamping position by inhibiting any movement of the head of the clamp away from the arm after the clamp has been moved to itsclamping position.

Title: Method and apparatus for identifying words described in a page description language file
Inventor: AYERS ROBERT M
IPC: G06K9/68
Filed: 1995-07-28
Abstract: A method and apparatus for identifying words described in a page description file. A computer device stores a page description language file which includes characters that have not been identified as words by the page description language. A word identifying mechanism reads the page description language file and groups characters to form at least one word from the characters. The system preferably transfers words to a client process capable of processing words at a request of the client process. In a method for identifying words from a page description file, characters are read from the file and are stored in a word buffer until a word break is detected based upon character position data stored in the file. The contents of the word buffer are then provided to a client process as an identified word. The method can also sort the characters from the file into a display order prior to storing the characters in the word buffer. The method and apparatus can be used for searching for words in a page description file.

Title: A method for handling redundant switching planes in packet switches and a switch for carrying out the method
Inventor: WAHLMAN JAN STEFAN ROBERT
IPC: H04L49/111
Filed: 1994-02-10
Abstract: To provide a correct outgoing stream of data packets for each established connection (having identifying number vc/vp) in a data packet switch, which comprises several parallel switching planes, which are identical to each other, there is for each output port for each switching plane (No. 1 and 2) and each established connection a buffer arranged to store at least one data packet.  When a first data packet arrives to an output port it is immediately tested by a control device for this output port, if this first data packet is the next data packet, which is in turn to be forwarded from the switch.  In a first case, when this condition is satisfied, the data packet is forwarded from the switch.  In a second case, when this condition is not satisfied, the data packet is stored in the buffer, which is arranged for the connection, to which said data packet belongs, and for the switching plane, through which the data packet has travelled.

Title: Downhole tool release mechanism
Inventor: LEMBCKE JEFFREY JOHN
IPC: E21B33/1295
Filed: 1996-05-06
Abstract: A system for releasing a downhole tool such as a packer is revealed which allows the tool to retain its set position against a very high loading force which can occur during operations such as perforating or acidizing or other formation treat-ments. Subsequently, before environmental conditions can adversely affect the integrity of the locking mechanism which employs a movable sleeve or equivalent,the release mechanism involving such a sleeve or equivalent is actuated. This disables one of the locking mechanisms on the tool and enables a shear-release mechanism, which is preferably set at a fairly low shear force to facilitate simple removal of the downhole tool at a later time when it becomes necessary to retrieve it.
