Patent CA-2010932-A1 (CA)
Inventor: THANGAVELU KANDASAMY
IPC: B66B1/18
Filed: 1990-02-26
Abstract: Abstract Relative System Response Elevator Dispatcher System Using "Artificial Intelligence" to Vary Bonuses and Penalties An elevator system employing a micro-processor-based group controller (Fig. 2) communicating with the cars (3, 4) to assign cars to hall calls based on a Relative System Response  (RSR)  approach.   However,  rather  than  using unvarying bonuses and penalties, the assigned bonuses and penalties  are  varied  using  "artificial  intelligence" techniques based on combined historic and real time traffic predictions to predict the number of people behind a hall call, and, calculating and using the average boarding and de-boarding rates at "en route" stops, and the expected car load at the hall call floor.  Prediction of the number of people waiting behind hall calls for a few minute intervals are made using traffic levels measured during the past few time intervals on that day as real time predictors, using a linear  exponential  smoothing model,  and  traffic  levels measured during similar time intervals on previous similar days  as  historic  traffic  predictors,  using  a  single exponential smoothing model.  The remaining capacity in the car at the hall call floor is matched to the waiting queue using a hall call mismatch penalty.  The car stop and hall stop penalties are varied based on the number of people behind the hall call and the variable dwell times at "en route" stops.  The stopping of a heavily loaded car to pick up a few people is penalized using a car load penalty. These enhancements to RSR result in equitable distribution of  car  stops  and  car  loads,  thus  improving  handling capacity and reducing waiting and service times.

Inventor: PETZOLD WERNER P
IPC: B60W30/18
Filed: 1990-06-26
Abstract: ABSTRACT OF THE INVENTION           An improved clutch control system in a continuously variable transmission driven vehicle monitors driver selection of forward or reverse and implements the specific parameters for each.  The control logic provides a preselected time interval for sensing of a pressure drop associated with the transition from one operating mode to another, such as from neutral to forward.  The system provides for sensing that pressure drop and providing a desired fluid flow rate for clutch actuation consistent with the desired performance.  The system also monitors pressure in the fluid actuation system at the end of the predetermined interval to ascertain when the pressure reaches a desired higher level indicative of a control characteristic to provide desired vehicle response to driver demand.  Fluid flow to the clutch is controlled at a corresponding rate to provide a desired operating characteristic and to facilitate transition into a subsequent vehicle operating mode.  Length of time frame for the associated timer depends upon characteristics of specific engines.  The timer times out in a time normally required for reaching the desired, second pressure level to allow transition to subsequent operating mode.

Title: Sealed reenterable splice enclosure
Inventor: JAYCOX DONALD F
IPC: H02G15/076
Filed: 1990-06-27
Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for sealing a splice enclosure to protect cable splice connections retained therein.  The sealing member is a single piece body integrally formed of a suitable material which resists detrimental environmental effects and is resiliently compressible in an axial direction to seal the splice enclosure.  Axial compression of the sealing member is employed to create sealing forces both about the outer periphery of the sealing member and between the sealing member and cables projecting therethrough.  Reentry into the enclosure does not require destruction of the sealing member and does not require tapes, adhesives or other materials and is hence very time, labor and material efficient.

Title: Twist lock junction between refractory tubular shapes
Inventor: HUMINSKY DONALD D
IPC: B22D41/50
Filed: 1991-02-27
Abstract: TWIST LOCK JUNCTION BETWEEN REFRACTORY TUBULAR SHAPES          ABSTRACT OF THE DISCLOSURE     The   disadvantages   of   the   prior   art   are substantially overcome by a  twist  lock junction and method having the mating joints of refractory tubular shapes  formed  in  a  polygonal  configuration.    Each junction  includes  a  polygonal  female  recess  and  a complimentary  interfitting polygonal male projection. The female recess is dimensionally larger than that of the adjoining male projection.  When either the female or male joint is rotated clockwise or counterclockwise relative to the other, a multi point wedging or "twist lock" effect occurs.   This wedging condition offers a tighter fit than the conventional gravity or circular fit.   In addition,  this "twist lock" effect squeezes the mortar applied to the joints and forces a thin seal near the sites of the point loading.   This decreases the chance of metal leakage or fracture of the mortar seal due to mechanical abuse.

Abstract: A B S T R A C T A product acceptance/rejection judgment method in an injection molding machine, which makes it possible to properly and quickly set judgment standard parameters and accurately judge whether a product is acceptable or not.  Based on injection pressures and screw positions periodically sampled during each of a plurality of injection processes in nondefective product molding, an injection pressure curve group represented as a function of the screw position and an injection pressure curve group represented as a function of the time period elapsed from the start of injection are displayed on two coordinate systems (6, 7) on a display screen.  Various reference values (x, p, t) and various upper and lower limit values (pu, pl, tu, tl, xu, xl) defining various permissible ranges for each of the screw positions and elapsed times that have been selected on the coordinate systems are set in data display fields (8, 9), taking into account the distribution of the pressure curve groups and displayed contents shown in a data display field (10) and changing with movements of cursors (11, 12).  During the execution of an actual molding cycle, each of the actual elapsed time period and actual injection pressure at each of selected screw positions, or each of the actual screw position and actual injection pressures at each of selected elapsed time periods is compared with its permissible range so as to check the acceptance/rejection of the same.  Based on the resultant number of rejections, the conformity of a product is determined.

Title: Liquid crystal display
IPC: G02F1/133
Filed: 1991-07-05
Abstract: LIQUID CRYSTAL DISPLAY                        ABSTRACT   Without the need of a data signal of high frequency such as a horizontal scanning frequency,  the polarity of data signal applied to one pixel can be inverted to the polarity of data signal applied to pixels horizontally and vertically adjacent to the one pixel  so that  a flicker cannot be recognized by an observer.  A first data signal is applied to every other column conductor of a plurality of column conductors and a second data signal is applied to remaining column conductors.  The polarity of the first data signal is inverted to that of the second data signal.   In one mode of the invention, the pixels in the same row are connected to the same row, and the pixels in one column are alternately connected to one column conductor to which the first  data  signal  is  applied  and  to the  other  column conductor to which the second data signal is applied.  The pixels in a column adjacent to the above one column are alternately connected to the above one and the other column conductors  with  one  pixel  being  shifted in  the  column direction with  respect  to  the pixels  in  the  above  one column.   In another mode of the invention,  the pixels in each  row  are  alternately connected  to  adjacent  two  row conductors,  and the pixels in each column are alternately connected to one column conductor to which the first data signal is applied and to the other column conductor to which the  second data  signal  is  applied.   In both modes,  the frequency of the first and second data signals can be made a flame frequency.  If the number of row conductors are 550, the frequency of data signal is 550 times smaller than prior art.

Title: Method of making laminated glazing units
Inventor: TWEADEY ROBERT F II
IPC: B32B27/06
Filed: 1991-10-21
Abstract: ABSTRACT OF THE DISCLOSURE    A method of making a laminated glazing unit having an  interfacial  coating  on  a  laminated ply  includes depositing the coating on the laminated ply and then removing  a  peripheral  portion  of  the  coating. Specifically, the peripheral portion of the coating is exposed to a laser beam of sufficient power to remove the coating.    The  exposure  time  and  power  level  are controlled to avoid damage to the underlying substrate. Subsequently, the coated substrate ply is laminated to a ply  of  PVB  or  other  flexible  polymeric  laminating material.   A substantially direct laminating bond is formed between the laminating ply and the surface of the substrate ply in the peripheral area from which the coating has been removed.   The peripheral seal thus formed  is  environmentally  durable  and  protects  the interior  of  the  interface  from  degradation  due  to progressive edge corrosion and the like.
