Patent CA-2057265-A1 (CA)
Title: Catalytic combustion
Inventor: LYWOOD WARWICK J
IPC: F23C13/00
Filed: 1991-12-09
Abstract: Abstract Catalytic Combustion A combustion process, eg for a gas turbine, comprises catalytically combusting part of a fuel/air feed in a preliminary catalyst body which has through passages and supports, or is composed of, a catalyst active for the combustion of the fuel. The resultant heated gas stream is then mixed with the remainder of the feed, and that mixture is combusted, eg catalytically in a main catalyst body.  The amount of combustion occurring in the preliminary catalyst body is sufficent that combustion of the mixture of the heated gas stream and the remainder of the feed can be sustained at the desired operating conditions.  Under those desired operating conditions combustion of the feed could not be sustained in the absence of the heating given by the combustion in the preliminary catalyst body.  There may be more than one preliminary catalyst body.  The preliminary catalyst body or bodies may also be provided with passages wherein combustion does not take place under the desired operating conditions so that those passages act as a bypass.  Preferably the combustion passages of at least the first preliminary catalyst body are of such size, that at the normal operating conditions, the flow therethrough is laminar, whereas the flow through the passages of the main catalyst body, where employed, is turbulent.

Filed: 1992-08-27
Abstract: A wireless communications network includes a local area network connected to a plurality of nodes which perform bidirectional wireless communication with mobile stations as controlled by a controller. Each node has a geographic area, termed a cell, within which mobile stations can communicate with the node associated with the cell. A cell interference graph is read into the controller, and a maximal independent set of nodes is determined. Each node in the maximal independent set of nodes are put in a set termed ACTIVE for performing wireless communication with mobile stations in their respective cells. Nodes which are not in the maximal independent set of nodes is put in a set termed WAITING to wait for permission to enter the set ACTIVE. A node in the set ACTIVE which has completed communications sends a completion signal to the controller. The controller then examines which of the nodes in the set WAITING is not adjacent to another node in the set ACTIVE, and such nodes are entered in a set termed CANDIDATES. Nodes in the set CANDIDATES are moved to the set ACTIVE according to predetermined criteria.

IPC: B41J2/165
Filed: 1992-09-30
Abstract: If it is detected that the number of times of ejection recovery operations performed in the past by the request of a user during an ink jet recording operations is greater than or equal to a designated relatively large value, for example "2", the ink jet recording apparatus judges that an ejection recovery operation is relatively necessary for itself and that the number of times of ejection recovery operations to be performed when the electric power supply is turned on is increased.  As a result in the ink jet recording apparatus, it will be appreciated that an optimal ejection recovery operation can be established in response to an operational condition of the ink jet recording apparatus and that the unnecessary waste of ink fluids can be prevented and the size of the recording apparatus can be reduced.

Title: Latch and file retaining arrangement for a file box
Inventor: AALDENBERG ERIC R
IPC: E05B55/00
Filed: 1992-10-13
Abstract: A file box has an improved latch and file retaining arrangement.  The latch includes a hook-like member on the lid which engages with a latching mechanism.  The latching mechanism includes a latch cover which is connected to the body of the box by a hinge.  The hinge is pivotally affixed to both the latch cover and the body of the box.  The latch cover may be swung into position to engage the first hook-like member and held into position to close the lid onto the box.  The hook-like member and latch mechanism may be recessed into the lid and box body, and shaped to conform to the overall shape of the box, thus creating a smooth, uninterrupted look to the closed box.  The hinge may be sized and shaped to fit within the latch cover to hide it from view when the lid is closed.  The file retaining arrangement has a channel at the open end of the box body along its two sides. The channel is defined by an outer wall and an inner wall having a  terminal  edge,  which  supports  the  file  folder's  hanging element.   The channel accommodates the hanging element.   The arrangement also has a file retaining wall located generally above the inner wall when the lid is closed.  The file retaining wall has a second terminal edge.  The first and second terminal edges are separated by a vertical distance greater than the height of the portion of the hanging element supported by the first terminal  edge, but no greater than twice that height, thereby preventing the hanging file holders from falling off of the first terminal edge, even if the closed box is inverted.

Title: Apparatus and method to train operators of speech recognition system
Inventor: HIRSH HANAVI M
IPC: G10L15/06
Filed: 1992-11-25
Abstract: Abstract In a continuous speech recognition system of my design which employs operator-generated word-marker signals, this invention provides an improvement in the form of a system which trains operators to send signals which coincide in time with the onset of speech production for each word.  Those signals act as markers which explicitly delimit the individual words in an utterance. The problem of large vocabulary continuous speech recognition is extremely difficult, if not intractable, given the current state of recognition technology.  The recognition of utterances composed of words separated by pauses, however, is a much simpler problem which can be readily handled by available methods and apparatus. Once an utterance has been divided into word-length segments by marker signals, its subsequent analysis is greatly simplified as the initial problem has been reduced to the level of difficulty of a recognizer that deals with words which are separated by pauses. The system of this invention provides six graduated exercises which facilitate the training of operators of my speech recognition system.  Someone with ordinary abilities can soon learn to send the required word-marking signals with an acceptable degree of precision. The fifth of the six levels provides the user with helpful prompts during what is otherwise the normal recognition process.  Such prompts can be used beyond the training period, as a regular mode of operation of the speech recognition system, but this will not be practical for all applications.

IPC: A61Q17/04
Filed: 1991-05-16
Abstract: A melanin that is soluble in an aqueous solution at a pH of at lest 5 to 9 at a temperature of 0 to 100 ·C. The melanin is further characterized by being capable of being filtered through at least a 0.45 micron size filter. Still further, the melanin is characterized by having a molecular weight of greater than 10,000 kilodaltons. The melanin is useful for providing a naturally-appearing tan to mammalian skin and hair. Such melanin can be produced by combining dopachrome and 5,6-dihydroxyindole (or allowing dopachrome to spontaneously form 5,6-dihydroxyindole) and an appropriate enzyme or by combining 5,6-dihydroxyindole and 5,6-dihydroxyindole-2-carboxylic acid or by incubating 5,6-dihydroxyindole-2-carboxylic acid alone. The melanin is also useful for providing a sun-screen to mammalian skin and hair, to treat post-inflammatory hypo- and hyperpigmentation, to tint glass and plastic, to protect industrial materials against ultraviolet damage, and as a coloring agent in foodstuffs such as coffee, tea, soda, whiskey and liquors.
