Title: Apparatus for severing sections from a web of material provided with transverse lines of perforations
Inventor: HENZE RAINER
IPC: B26F3/02
Filed: 1992-05-29
Abstract: 1090-9 AN APPARATUS FOR SEVERING SECTIONS FROM A WEB OF MATERIAL PROVIDED WITH TRANSVERSE PERFORATION LINES An apparatus is provided for severing sections from a web of material having transverse perforation lines and preferably from single or multiply tubular paper having transverse perforation lines. The apparatus consists of a retaining double belt conveyor and of a tear off double belt conveyor, arranged at a distance in the conveying direction downstream from the retaining double belt conveyor. In the retaining double belt conveyor the bend and or idler rolls or rollers of the conveyor belt or belts on the lower side of the web of material are offset in the longitudinal direction in relation to the bend in idler rolls on the top side so that the web of material passes through the retaining double belt conveyor in a corrugated manner. In the tear off double belt conveyor the conveyor belts are arranged on the lower and top sides of the web of material with an offset. In order to simplify the design, the idler rolls of the upper and of the lower conveyor belts of the tear off double belt conveyor are also positioned in relation to each other so that the web of material runs through the tear off double belt conveyor in a corrugated manner. The tear off double belt conveyor is driven at approximately the same basic speed as the retaining double belt conveyor. Intermittently the tear off double belt conveyor is driven at a higher speed when one or more transverse perforation lines are located at a point of severance between the retaining double belt conveyor and the tear off double belt conveyor.

Title: Method for repairing a rotor
Inventor: AMOS DENNIS R
IPC: F01D5/06
Filed: 1992-12-01
Abstract: A method for repairing a rotor includes severing the rotor into two or more rotor segments. After removing a portion of material including the crack from the rotor, weld metal is deposited onto the rotor until the removed portion is replaced with weld metal. A built-up portion is welded onto a surface positioned adjacent a bore of each of the rotor segments. One of the built-up portions is machined into a female spigot and the other built-up portion is machined into a male spigot for engagement of the rotor segments. The female and the male spigots are engaged far alignment of the rotor segments. The rotor segments are welded together with weld metal, which is deposited in a welding groove formed between the rotor segments and the spigots. After the rotor segments are joined together, the male spigot, the female spigot, and a portion of the weld metal positioned near the root fusion area are removed to restore the bore of the rotor to its original diameter.

Inventor: LUPTON STEPHEN D
IPC: C12N15/62
Filed: 1991-11-12
Abstract: The invention provides selectable fusion genes comprising a dominant positive selectable gene fused to and in reading frame with a negative selectable gene. The selectable fusion gene encodes a single bifunctional fusion protein which is capable of conferring a dominant positive selectable phenotype and a negative selectable phenotype on a cellular host. A dominant positive selectable phenotype is conferred, for example, by the hph gene for hygromycin B resistance (Hm~). A dominant negative selectable phenotype is conferred, for example, by the HSV-I TK gene for gansiclovir sensitivity (GCV5). The present invention also provides recombinant expression vectors, for example, retroviral vectors, which include selectable fusion genes, and cells transduced with the recombinant expression vectors. The bifunctional selectable fusion genes are expressed and regulated as a single genetic entity, permitting co-regulation and co-expression with a high degree of efficiency.

Title: Directly connected display of process control system in an open systems windows environment
Inventor: KILGORE WILLIAM B
IPC: G06F3/048
Filed: 1993-06-02
Abstract: In a display for a process control system, the display can be generated by one of two different sources, but is controlled by only one of them.  A process control system network provides a first source of display, while a windowing system provides a second source.  The control system network provides crucial information to the display regarding the operation of the process control system.  Alternatively, the windowing system allows displays to be generated from a variety of sources including external computer systems. The windowing system controls the display by opening and maintaining windows.  One specific window to be opened is a window in which the control system network can display information.  To allow the control system network to communicate information, a window is opened by the windowing system, and then the process control network is allowed to overwrite information into this newly opened window.          Also, should the windowing system fail, control of the display is given to the control system network.

IPC: B01D3/22
Filed: 1993-08-04
Abstract: CATALYST-DOWNCOMER-TRAY FOR CHEMICAL PROCESS TOWER               ABSTRACT OF THE DISCLOSURE      Improved  catalyst-downcomer-tray  assemblies  for vapor liquid contact towers.  Downcomers are constructed for receipt of bundles of catalyst media used to promote chemical reactions therein.  Raised, perforated regions of the underlying trays are then disposed therebeneath for improving mass  transfer efficiency.    The  raised regions reduce fluid pressure to vent excess vapor from downcomers and trays therebeneath.  The vapor generated within the downcomers from the catalytic reaction may then be selectively directed into the liquid discharged from  the  downcomer  disposed  on  the  tray  above  and imparted with a horizontal flow characteristic.  In this manner the catalytic reaction vapors can be effectively released to facilitate a stabilized vapor-liquid flow configuration with improved chemical reaction occurring in the downcomer of the process tower.
