Title: Method and apparatus for obtaining process characteristics in a self-tuning controller
Inventor: MOLNAR RICHARD J
IPC: G05B11/42
Filed: 1993-03-31
Abstract: ABSTRACT The  characteristics  of  the  field  process  system controlled by a self tuning controller are obtained by analyzing the open loop response of the process variable to a step applied at the controller's control output.  A first-order system response with pure time delay is used to approximate a higher-order field process system's actual response.  The overall deadtime and time constant of the first-order approximation are determined. The maximum slope of the process variable response to the step is stored along with an assigned time of its occurrence and an assigned process  variable. The  stored  information  is  used  to approximate the overall deadtime.   In one embodiment the stored information is assumed to be the data obtained from a second-order response having a 10:1 time constant ratio and is used to find the assumed second-order time constants which are used to find the first-order time constant.  In a  second  embodiment the  first  order  time  constant  is determined by using a convergence point falling within a predetermined range between the actual response data and the first-order approximation.  The step is not applied to the control output until the process variable has reached the initial steady state condition and the calculation of slope ceases when the process variable response reaches the final steady  state  condition.    Alternative  techniques  are disclosed for determining the steady state condition.

Title: Ultrasonic position locating method and apparatus therefor
Inventor: EDWARDS BRUCE
IPC: G06F3/0346
Filed: 1991-10-21
Abstract: A positional locating method and apparatus (10) for measuring distances by accurately determining the transit time of ultrasonic wave bursts (22) between two or more points is disclosed. Timer clocks (60), (62), (64) and (66) are started when each of the bursts (22) is triggered to be emitted from a transmission point (14), and are stopped when a highly defined point (56) in the burst (22) is received at a corresponding receiving point (32), (34), (36) and (38). The highly defined point (56) is determined by first analyzing the burst (22) to identify a particular cycle (54) within the burst (22). That particular cycle (54) is then analyzed to detect the specific point (56) within the cycle (54). Use of multiple transmitters (9312), (9314) and (9316) or receivers (932), (934) and (936) permits the calculation of position within two or three physical dimensions using ordinary trigonometric calculations. The inventive method also has sufficient resolution to permit the calculation of attitudinal data by detecting very fine positional differences in a plurality of reference points located at relatively close distances on a movable marker device (912). An input device of the present invention comprises a control means, a transducer means, and a mouse. In a 6D mode of operation, three-dimensional positional information with three degrees of freedom is provided to the computer.

The propelling stick has a radius slightly less than that of the arc in the groove to provide a close tolerance between the stick and the groove.   The depth of the groove is greater than the radius of curvature of the arc but less than the diameter of the stick to provide ground rolling and aerial manipulation of the disc by the propelling stick.

Title: Optical Interconnection of Photonic Circuits
Inventor: PENG PETER
IPC: G02B6/38
Filed: 1993-08-16
Abstract: A technique for interconnecting photonic circuits employing a fixed field of optical couplers situated between adjacent layers of photonic circuits. The coupler field facilitates the direct connection of optical fibers linked to components in one of the adjacent layers of photonic circuits with optical fibers linked to components in another adjacent layer. Each optical coupler within the field is a standard, commercially available optical fiber coupler which mates the optical fibers via a single low-loss connection. In addition, as each of these connectors allows easy connection/disconnection of optical fibers reconfiguring previous inter-layer connections is simplified. In a particular embodiment, the coupler field includes a plurality of individual couplers arranged in a regular geometric pattern upon a panel oriented at a 45° angle with respect to the circuit packs of the adjacent layers. This provides easy access to the couplers, and allows for uncomplicated indexing of each connection.
Patent CA-2104434-A1 (CA)
Title: Second hand smoke filter
Inventor: PATTERSON BRIAN ROBERT
IPC: A24F13/00
Filed: 1993-08-19
Abstract: Abstract When  cigarettes  or cigars  are  smoked  it  is known  they produce second-hand  smoke.   Second-hand smoke  is excess  smoke from the cigarette or cigar not inhaled by the smoker and second-hand smoke is also smoke exhaled by the person smoking.    In this invention the cigarette  or cigar is inserted into a casing with  a hole  the size  of the cigarette or  cigar.   The casing is preferrably divided into two chambers but may only have one.  The hole the cigarette  or cigar is inserted into leads  to one  chamber,  a spout  leads to  the second  chamber, or  in the instance of a single chamber casing it leads to the same  chamber as the cigarette.  The casing has holes in the cigarette or cigar chamber to  provide oxygen  for  combustion of  the cigarette  or cigar.  These holes  are covered by filters to  filter any excess smoke  particles  produced  by the  burning  cigarette  or cigar.     These filters can be various media from activated carbon to glass fibre to porous  plastic or combinations of these  or other known filter media.   The second chamber  of the casing is  filled with filter.   Smoke exhaled from  the smoker is directed  through the spout into the  second chamber filled with filter.  This filters the smoke particles from the exhaled breath.   In the instance of a single chamber casing the  filters that filter the excess smoke produced  by the cigarette  or  cigar  also filter  the  exhaled breath.

Title: Yeast-leavened refrigerated dough products
Inventor: DOMINGUES DAVID J
IPC: A21D10/00
Filed: 1992-07-14
Abstract: The present invention provides refrigeratable yeast-leavened dough compositions and methods of making such doughs. In a first embodiment, a dough composition of the invention is made by rehydrating dried yeast at chilled temperatures, which causes selective lysing (a loss in the selectivity of the yeast plasma membrane). Such a dough composition exhibits a cold sensitiv-ity in that the yeast is capable of leavening the dough at elevated temperatures, but becomes inactive at refrigeration temperatures. In another embodiment, the dough composition and the strain of yeast used therein are chosen to limit the total leavening action of the yeast by controlling the amount of substrate in the dough fermentable by the yeast. In a third embodiment, a dough com-prises a mixture of flour, water and a mutant yeast which is low temperature sensitive. Such an "Its" yeast is active at elevated temperatures, but becomes substantially inactive at refrigeration temperatures. Dough compositions made in accordance with any of these embodiments of the invention are capable of being leavened at elevated temperatures, yet stored in a sealed container at refrigeration temperatures for extended periods of time.

Title: Rod pump flow rate determination from motor power
Inventor: LONDON ROBERT K
IPC: F04B49/06
Filed: 1994-03-22
Abstract: ROD PUMP FLOW RATE DETERMINATION FROM MOTOR POWER            Abstract of the Disclosure A pump controller coupling the electric motor of a cyclically operating well pump to a power line is arranged to measure instantaneous power consumption of the motor, to integrate the power consumption over pump cycles, and to assess the performance of the well and/or pump by using the total  power  consumption  to  estimate  fluid  flow.    The controller determines a phase reference in the cycle of the pump by monitoring for a peak or zero crossing in the instantaneous power level, specifically the point at which the pump changes over from a power stroke to regenerative operation due to pump momentum.  The integrated total power consumption is reduced by an offset factor representing frictional losses, and scaled to obtain an approximate fluid volume determination for the pump and well.   The factors used for offset and scaling can be adjusted by calibration using at least intermittent measurements of actual fluid flow and fluid density.   The offset factor representing friction can be monitored for deciding when maintenance is needed on the pump.
