Abstract: Apparatus for controlling at least one variable output parameter in response to a variable predetermined input parameter in a process system, such as a digital thermostat. The apparatus provides adaptive control of the output variable by utilizing a controller means that includes an adaptive controller means, an identifier means and a tuner means.  The identifier means defines a model  having parameters which represent  the operational  characteristics  of the process system, and the identifier means monitors the operation of the adaptive controller means and selectively changes the parame-ters of said model to improve the operation of the adaptive controller means.  The tuner means receives the model parame-ters from the identifier means and calculating robust and reliable  values  of  said  predetermined  gain  factors  and applying the same to the adaptive controller means for use thereby.
Patent CA-2130021-A1 (CA)
Inventor: KRUMMENACHER JOSEF
IPC: B29C45/28
Filed: 1994-08-12
Abstract: The injection nozzle comprises a thin-walled centering bushing inserted between the tip insert and the mold insert. The centering bushing engages a shoulder of the mold insert and thus achieves a mutual centering and sealing of the tip insert and the mold insert. This avoids the inflow of molding material into the cavity between the tip insert and the mold insert which would impair or delay the changing of colors of the material, and the injection needle is effectively centered so that a cylindrical tip portion can close a very short cylindrical portion of a gate bore. The heat transfer between the heated nozzle parts and the mold insert is nevertheless maintained at a low level since the mutual centering is obtained by narrow contact sites.

Patent CA-2131195-A1 (CA)
Title: Method of Improving Oil and Gas Well Productivity
Inventor: LOREE DWIGHT N
IPC: E21B43/16
Filed: 1994-08-26
Abstract: A method  of  improving  oil  or  gas  well productivity from a well penetrating a formation in an oil or gas reservoir,  by forming a load fluid by obtaining  a  hydrocarbon  fluid  containing  a  known percentage of aromatics and adding an amount of CO2 to the hydrocarbon fluid that is determined according to a predetermined miscibility relationship between the CO2 and the hydrocarbon fluid that establishes the amount of CO2 required to form a bank of CO2 ahead of the load fluid in the formation. The load fluid is applied to the well at a pressure such that CO2 in load fluid within the well bore remains in solution and CO2 in load fluid within the formation leaks off the load fluid into the formation and forms a bank of CO2 ahead of the load fluid. The surface pressure is released from the load fluid and the load fluid flows back out of the well. The miscibility relationship between CO2 and hydrocarbon based load fluids depends on the aromatic content of the load fluid.  For high pressure wells, since  the  amount  of  CO2  required becomes excessive, it is preferable to use a load fluid that requires a smaller amount of CO2 to form a bank in front of the load fluid for a given amount of the load fluid, hence one that has a lower amount of aromatics.  The aromatic content of the hydrocarbon fluid is selected according to the pressure required for the well treatment.

Abstract: A CONTROL SYSTEM FOR CHANGING AUTOMATIC GEARS               ABSTRACT OF THE DISCLOSURE    The invention concerns a control system  (10)  for changing automatic gears (3) that operates according to fuzzy logic methods.  All the fuzzy-production rules are divided into at least three sections:   a set of basic rules  to  determine  the  gear-changing  point  in  a consumption-oriented driving style, a set of adaptation rules to modify the set of basic rules depending on a current driving style and an identification set of rules for classifying the driver according to his/her driving style.  By way of a supplementary set of adaptation rules the  set  of  basic rules  can be additionally modified according to a current driving condition.   Individual function blocks (11 to 15) operate preferably according to the same inference mechanism.  Gamma operators are used in order  to  approximate  as  closely  as  possible  human behavior.  A process is proposed for generating membership functions to determine a running condition by  fuzzy-production rules.  In a preferred embodiment the adaptive gear-changing behavior is activated by forming offsets. Priorities  are  allotted  to  the  rules  especially  for reasons of safety and reliability.

Abstract: The valuing element is positively tied to a pressure-sensing and -responsive diaphragm, via a diaphragm-carried insert. The connection is so arranged as to permit relative angular displacement, tetween the valuing element and the diaphragm, so that cocking of the element, in its axial movement, will not occur. The gas filter is formed of a sintered plastic to avoid corrosion and flaking off of metallic particles. An aspirator hole communicates the diaphragm with the low-pressure chamber outlet, but has an artificially lower pressure, than the outlet pressure, introduced to the diaphragm. through the use of an ejector nozzle.      A hole formed in the bonnet establishes atmospheric pressure above the diaphragm, but a porous plug in the hole prevents any ingestion of water, from puddle-splashing, take up from wet roads. and the like.
