Title: Method and system for increasing the maneuverability and slowing the speed of ships without involving the propulsion, rudder or bow thruster systems
Inventor: GLEAVES STEPHEN
IPC: B63H25/44
Filed: 1996-11-07
Abstract: A method and system for increasing the maneuverability and slowing the speed of ships is designed to be simple, reliable, low in cost, flexible in operation, independent of the ship's propulsion and rudder system, easy to install both on new and on existing ships, simplifying the aft ship's structure, rudder and propulsion systems, efficient in eliminating the collisions of ships with surrounding objects and the other ships, increasing the ship's maneuverability, decreasing substantially and controlling the ship's crash stop distance without using the ship's propulsion system, increasing the ship's safety and safety of navigation in the respective area. The system is built-up of independent identical modules, each module being able to work both independently or together with the other modules as a system both to increase the ship's maneuverability and to decrease the ship's speed. The modules are placed symmetrically on both sides of the ship. Each module includes a flap controlled by a hydraulic cylinder. The assembly of all hydraulic cylinders is controlled independently or as a group from the ship's wheelhouse. The flap of the module is normally inside of the ship's hull and opens to oppose the water circulation near the ship's hull. The number of flaps opened on both sides determines the ship movement. When an equal number of flaps is open on each side the ship's speed decreases, the number of open flaps determining the crash stop distance, When the number of flaps open on both sides is not the same, the ship moves towards the side with more open flaps, thus increasing the ship's maneuverability and decreasing the ship's speed. If a reduced number of flaps are open on one side the effect is the same as the one of a rudder. The system is a complete back-up system for the rudder system and for the propulsion system in a breaking system mode. The system improves the maneuverability of ships and their breaking capacity in case of complete ship black-out even when the ship's rudder and the propulsion systems are out of operation.

Title: Mounting system for pressure transmitters
Inventor: BELL JOEL DAVID
IPC: G01F15/18
Filed: 1995-05-02
Abstract: A mounting plate is disclosed that is adapted to be positioned between a main flow line and at least two differential pressure transmitters, to place the two differential pressure transmitters in fluid communication with a pair of pipeline taps. The mounting plate includes a plate like body generally rectangular in cross section.

Patent CA-2192996-A1 (CA)
Inventor: WILLMANN GERT
IPC: H04Q11/04
Filed: 1996-12-13
Abstract: The invention concerns a method of establishing a multichannel connection comprising N channels, two switching facilities, a communications network, and a transmit-side and a receive-side access facility to a communications network.  When a multichannel connection (SLOT3, SLOT7; SLOT5, SLOT28) is established through a switching network (DSN), first the transit times (T1, T2, T3) of more than N channels through the switching network (DSN) are determined (MONIT).  Then N channels are selected from said more than N channels by means of an algorithm (CONTR), which uses the determined transit times (T1, T2, T3) as input values.  Subsequently the selected N channels are assigned as channels to the multichannel connection (SLOT3, SLOT7; SLOT5, SLOT28), and for their synchronization the channels are delayed in accordance with the determined transit times (T1, T2, T3).  This method is also applicable to end-to-end multichannel connections and single channel connections.

Inventor: AHMED ASIF SYED
IPC: A61K31/417
Filed: 1995-11-30
Abstract: The use of an agent for controlling vascular permeability within the cervix is disclosed for controlling cervical ripening. To hasten cervical ripening, the agent is one which increases vascular permeability, e.g., vascular endothelial growth factor (VEGF) or platelet-activating factor (PAF). If cervical ripening is to be delayed, the agent is one which reduces vascular permeability, e.g., a VEGF receptor antagonist or antibody or a PAF receptor antagonist or antibody. The agents of the present invention can be used as a means of managing labour.

Title: A metering system
Inventor: HAYES ROBERT A
IPC: G08C17/00
Filed: 1997-01-23
Abstract: A metering system (10) provides a measuring level (12) with multiple meters (20a-20k) and a collection level (14) with multiple collectors (22a-22c). Each meter (fig. 2) periodically measures a parameter, such as electricity consumption, and stores measurement information. Each meter (fig. 2) periodically transmits its stored measurement information to a collector (fig. 8) by a wireless signal (24). When a collector (22a-22c) receives a transmission (24), it determines which meter (20a-20k) sent the transmission (24), and then extracts unprocessed measurement information. The collector (fig. 8) then processes the measurement information to generate a metered function, such as a load profile (fig. 13), a time-of use profile (figs. 14A & 14B), or a demand profile (figs. 15A & 15B). The collector (fig. 8) can compensate for missed transmissions (24) and power failures. The metered functions for each meter (20a-20k) are transmitted from the collectors (22a-22c) to a monitoring station (26).

Such proteins termed herein as "enhancins" are found within the viral occlusion body, have a disruptive effect on the insect peritrophic membrane (PM) proteins, and/or interact with the midgut epithelium in such a manner as to permit the increased adsorption, penetration and uptake of virus particles by midgut cells with a concomitant increase in host mortality.  Disclosed herein is a recombinant DNA sequence which codes for the enhancin protein of the Helicoverpa armigera granulovirus virus. The DNA sequence is shown in SEQ. ID. NO. :1 and the open reading frame is shown in SEQ. ID. NO.:  1: base pairs 271-2976. The amino acid sequence of the enhancin protein is shown in SEQ. ID. NO.: 2.

Title: Rod holder with separate positionable contact elements for rod metering
Inventor: LIANG SHIHUA
IPC: B05C1/08
Filed: 1996-06-06
Abstract: A rigid metal housing is positioned downstream of a coating applicator. The housing supports a plurality of positionable contact elements formed of a low friction, high wear-resistant material, which extend inwardly from the housing to engage a slow speed rotating rod. At least one of the contact elements is adjustable to support the rod for stable rotation, and to retain an effective seal between the contact elements and the rod to thereby prevent leakage of clearing/lubricating fluid into the applied coating. The contact elements may be advanced inwardly as the elements and the rod wear, thereby extending the effective life of the rod holder apparatus.     Screws may bear against a rear contact element through segmented backing plates allowing refinement of the coat weight along the width of the substrate. Furthermore, an air tube may be positioned between the housing and a rear fixture to adjust overall coating thickness.

Abstract: A computer implemented method is applied to convert a formatted document or text to an ordered list of words. The formatted document is first partitioned into first and second data structures stored in a memory of a computer. The first data structure stores text fragments, and the second data structure stores code fragments of the formatted document.  Adjacent text fragments are concatenated to form possible ordered word lists.  Possible words are matched against a dictionary of representative words.  A best ordered word list having the fewest number of words is selected from the possible ordered word lists.
