Abstract: A method and system for determining the minimum number of rearrangements for connecting an input gate to an output gate through a rearrangeably blocked communications matrix represent the communications matrix by a square matrix having a first dimension that represents the input stage switches of the communication matrix, and a second dimension that represents the output stage switches of the communications matrix, and wherein the square matrix has cells each representing an intersection of the first dimension with the second dimension and indicating a possible center stage switch connection through of the communications matrix. The method and system identify a blocked center stage switch of the communications matrix in terms of the first dimension and the second dimension and identify a pair of center stage switches, where one of which does not have the same output stage switch as the blocked center stage switch, and the other of which does not have the same input stage switch as the blocked center stage switch. In parallel, the number of rearrangement steps necessary for a rearrangement sequence through the communications matrix that uses the first center stage switch and, then, the number of rearrangement steps for a rearrangement sequence that uses the other center stage switch are determined. The method and system terminate these number determining functions upon first determining the rearrangement sequence requiring the smaller number of rearrangement steps.

Title: Other worlds war
Inventor: MELOCHE LEONARD J
IPC: A63F3/00
Filed: 1993-05-14
Abstract: Abstract This invention relates to games, and more particulary board games involving a plurality of players representing forces in conflict.  The game is played primarily on a grid-like playing field.  Planets are placed upon this grid, at different locations.  For each planet there are card(s) that represents resources that may be found on that planet.  Each player starts with one card and places his playing pieces on the planet indicated by the card. A player may obtain additional cards from the deck, or by seizing an opponents planet.  Each resource card a player has, that represents a planet he has forces on, will generate additional resources for that player.  There are three types of resources, and each resource is beneficial to the player.  One resource is used primarily to buy playing pieces, another is used to search for additional resource cards and to move playing pieces from one planet to another.   The third resource  is used to supply planets, allowing them to further generate resources. Each player has coloured pieces representing units that fight other players pieces, occupy planets, and allow for the transport of playing pieces from one planet to another.  Pieces are moved from one planet to another by removing them from the playing board and placing them on a separate grid that will hold the forces until they arrive at their destination.  The number of turns the pieces  spend on the  secondary  grid  depends  on  the distance the pieces are intended to travel on the playing board.  If the forces of two different players occupy the same planet they will fight with each other until only one player's forces remain.    Each player will try to increase the number of resources they collect, while curtailing their opponents. Eventually, one player will grow strong enough to defeat his opponents and seize their starting planets, thereby winning the game.

Filed: 1993-07-19
Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to a method for assessing  clinical activity  and  resistance to multiple anticancer drugs of mammalian cells, based  on  a  dose-dependent  inhibition with  cytotoxic  agents of the cellular rise in ornithine decarboxylase  activity,  following  serum   stimulation, which comprises the steps of: (d) determining by an immu-nological technique the rise in the ornithine  decarboxy-lase protein levels, after adding serum containing medium to quiescent  mammalian  cells,  and  (b)  obtaining the levels  of  the anticancer drug resistance from the ratio of 50% inhibitory concentration of the ornithine decarboxyla-se  obtained  with  anticancer  drug resistance cells and drug sensitive  cells.  The  immunological  technique  is selected from ELISA, radioimmunoassay,immunofluorescence, flow cytometry and fluorescence microscopy. The  increase in  the ornithine decarboxylase activity resulted from an increase  in  the  number  of   ornithine   decarboxylase molecules.

Title: Auto-ignition system for premixed gas turbine combustors
Inventor: MUMFORD STEPHEN E
IPC: F02C9/40
Filed: 1993-10-06
Abstract: ABSTRACT OF THE DISCLOSURE         A method and system for auto-igniting the pilot section of a gas turbine combustor prior to down-loading the turbine from base load operation.  A liquid fuel is employed that has an auto-ignition temperature which is less than the temperature of air which enters into the recirculation zone of the pilot section.  The liquid fuel is injected into the recirculation zone and auto-ignite , causing natural gas fuel which is also being injected into the pilot section to burst into flame, creating a diffusion flame in the pilot section. This permits operation of the pilot section in a premix mode where natural gas fuel mixes with air without a flame during base load operation, thus providing for low production of NOx emissions,  while ensuring maintenance of a flame in the combustor when the flame in the main burn section of the combustor is extinguished to allow for turbine unloading.

Title: Multi-stage torque proportioning differential
Inventor: GUIDONI SANDRO
IPC: F16H48/29
Filed: 1992-04-28
Abstract: A torque proportioning differential (10, 60, or 120) is modified to exhibit a bias ratio that varies with torque transmitted by the differential. Thrust forces (34 and 36, 88 and 90, or 144 and 146) generated within the differential are opposed by at least one pair of surfaces (38 and 40, 96, 98 and 104, 106, or 152, 154 and 156, 158) having different frictional characteristics. One of the surfaces (38, 96 and 98, or 152 and 154) opposes a portion of the thrust forces, and the other surface (40, 104 and 106, or 156 and 158) opposes a remaining portion of the thrust forces. A  control member (54, 100 and 102, or 152) responsive to the transmitted torque limits the respective portions of the thrust forces opposed by each of the two surfaces.

IPC: H01J23/54
Filed: 1994-10-18
Abstract: An inductive output tetrode includes a cylindrical ceramic envelope 1 within which is located an electron gun including a cathode 2 and grid 3. A resonant input cavity surrounds the envelope 1 and is located adjacent the electron gun so as to provide a modulating electric field in the cathode-grid region during operation to produce density modulation of the electron beam. The cavity 7 is connected to two metal cylinders 10 and 14 arranged immediately adjacent to the outside of the envelope 1. Metallic portions 12 and 15 located within the envelope 1 are co-extensive with cylinders 10 and 14 with the material of the envelope 1 being located between them. These act as r.f. chokes to reduce high frequency losses from the cavity 7. Tuning of the resonant cavity may be achieved by adjusting a tuning member 8 which is at distance of quarter of a wavelength at the resonant frequency from the cathode-grid region.
