Inventor: RUSSELL EDWARD A
IPC: H04L29/06
Filed: 1993-11-09
Abstract: A server for executing operation calls by a client, including a dispatcher, a plurality of worker tasks, and a dispatcher shared memory area and worker control block for each worker task. Each operation call provided from a client is a sequence or one or more remote procedure call requests and each includes a packed buffer containing parameters. The dispatcher receives a buffer directly into the dispatcher shared memory space of the worker task selected to execute the remote procedure call request. sets the semaphore and sends a request acceptance response. The selected worker task unpacks the buffer into its memory space, executes the request, places the results into a packed buffer in its dispatcher shared memory area and sends a remote procedure call to the dispatcher.  The dispatcher executes a remote procedure call to the client and sends the result buffer directly from the shared memory area. The server further includes a dispatcher state save mechanism and the remote procedure call from the worker task includes an identifier of the corresponding saved dispatcher state for the request. The packed buffer associated with a request includes client information and each worker task stores the client information in a worker shared memory space common to the worker tasks and each request of an operation call may be assigned to a different worker task.

Title: Coded seal
Inventor: YUEN KI S
IPC: G09F3/03
Filed: 1995-01-17
Abstract: The present invention is directed to a coded seal which allows a device to determine whether unauthorized access to a terminal or other electronic or security device has been made. The code includes a series of continuous and discontinuous members which are used to form a code. Breaking of the seal causes the members to be discontinuous and makes it difficult to determine what the code was. In this way, it is difficult to replace the seal, as this would only be successful if the replacement seal had the same code.

Title: E.s.e. system ecology safe exhaust system
Inventor: SCAPPATURA DOMINIC E
IPC: F01N13/02
Filed: 1995-03-27
Abstract: This invention when employed will result in the elimination of specific contaminant and reduce heat and vapours from the emission of an internal combustion engine. This system comprises of a baffled heat exchanger which receives its cooling ability from the existing air-conditioner unit of the automobile and drastically reduces the exhaust temperature so that the vapours condense to a liquid and the gases are cooled. The products of the cooling process can now be treated in the chemical filter trap of this system which neutralizes and extracts the acid. The liquid flows and drains into a neutralizing tank while the gases are forced out through a chemical field extruding acids and nitrates prior to leaving the filter trap. The final components deal specifically with Carbon Monoxide chemical filtration, removal of hydrocarbons and particles by filtration and the elimination fine particles and vapours by a fine membrane filter resulting in a cool clean exhaust.

Title: Method and apparatus for treating an engine exhaust gas stream
Inventor: BURK PATRICK LEE
IPC: F01N3/28
Filed: 1993-11-19
Abstract: A method and apparatus in accordance with the invention is described which comprises treating an engine (12) exhaust gas stream containing hydrocarbons and other pollutants. The method of this invention comprises the steps of flowing the exhaust gas stream through a catalytic member comprising a monolith body (16) having a first catalyst zone (18) and a second catalyst zone (28) therein to contact a catalyst in a first catalyst zone (18) to convert at least some of the pollutants in the exhaust gas stream into innocuous products. The exhaust gas stream is then discharged from the catalytic member and flowed through an adsorbent zone (24) to adsorb at least some of the hydrocarbon pollutants with an adsorbent composition. The exhaust gas stream is then discharged from the adsorbent zone (24) and flowed to the second catalyst zone (28) to convert at least some of the pollutants into innocuous products. The exhaust gas stream, so treated, is then discharged to the atmosphere through suitable dis-charge means. A preferred adsorbent is a zeolite, having a relatively high silica to alumina ratio and a low relative Bronsted acidity. The preferred adsorbent compositions comprise Beta zeolites. An oxidant such as air (32) may be added to the exhaust gas stream at a point upstream of the second catalyst zone.

Title: Methods and apparatus for identifying faulted phases on an electric power transmission line
Inventor: JONES MARTIN S
IPC: H02H7/26
Filed: 1995-04-06
Abstract: The invention provides method and apparatus for identifying the faulted phases on the occurrence of a single phase fault simultaneously on both circuits of a double circuit electric power transmission line using measurements taken at the one end of the line and a knowledge of various parameters of the line, a signal representative of the travelling wave arriving at the one end of the line in consequence of the faults is derived. This derived signal is used to deduce the values of the components of the derived signal attributable to the different faults for each of a number of assumptions as to which phases are faulted. The deduced values for the different assumptions are then used to determine which assumption is most likely to be correct.

Inventor: CHASSE DANIEL
IPC: G06F19/00
Filed: 1995-05-30
Abstract: A method is disclosed for using a numerical method such as finite elements to adjust a model of an object for use with computer integrated manufacturing. The adjusted model is useful in correcting errors introduced in manufacturing. The method requires the model to be available in an electronic form. An object produced based on the model is measured to produce an electronic facsimile. The two electronic representations are then correlated and some differences between them are found. With one or more of the differences, a phenomenon that would have caused the difference(s) is determined and applied in an inverse manner to the model. A system for carrying out the invention is also disclosed.
