Title: Energy-saving control apparatus and control method for induction motor
Inventor: HATANAKA TAKEFUMI
IPC: H02P23/26
Filed: 1992-08-05
Granted: 1995-12-19
Abstract: An energy-saving induction motor control apparatus maintains the operation of a motor at an optimum power factor irrespective of changes in motor load, by generating a power factor compensation value which is varied in accordance with the motor supply voltage.  The motor supply voltage is controlled such as to reduce any difference between the optimum power factor value and a measured power factor value, thereby ensuring that stable operation with minimum energy consumption are achieved over a wide range of motor load values.

Title: Determination of the number of persons entering and leaving an elevator car
Inventor: ROSCHIER NILS-ROBERT
IPC: B66B1/34
Filed: 1992-08-14
Granted: 1998-08-11
Abstract: The present invention provides a method for determining  the  number  of  passenger  transfers  in  an elevator car monitored by an elevator and group control systems under the supervision of a group control.  The method comprises continuously measuring a car load during a stoppage for obtaining a load data signal. The load data signal is filtered, recorded and the number of load changes taking place is determined therefrom, so that the number of persons having entered and having left the elevator car is calculated. The car load data measured with an analogous weighting device is converted into a digital car load signal which may be digitally filtered. The data obtained with this method may be verified with the elevator status data collected by the elevator control system (e.g. with photocells, load devices, car calls and direction data). The  present  invention  also  provides  an  apparatus  for determining  the  number  of  passenger  transfers.  The apparatus comprises: a weighing device  for  continuously measuring the car load during a stoppage; an A/D converter for converting the load data signal into a digital load data signal; and a  recording  and  calculation  unit.  A verification unit can be additionally arranged in the group control system. The recording and calculation unit and said A/D converter may be placed in an elevator control system panel and connected to the serial bus between the elevator control and group systems.

Title: Covering assembly for architectural openings
Inventor: ANTHONY JAMES M
IPC: A47H23/02
Filed: 1992-12-18
Granted: 1996-11-12
Abstract: A covering for an architectural opening such as a window or door is in the form of a vertically oriented fabric assembly having front and rear sheer fabrics interconnected by vertically extending vanes.  The vanes can be tilted through a series of carriers mounted on a track rail from which the covering is suspended in order to adjust the spacing between the fabrics between open and closed positions and adjust the light transmitting characteristics of the covering.  The covering can be extended across the opening by separating the carriers on the track rail and can be contracted by stacking the carriers toward one end of the track rail.  A unique design of carrier allows the covering to fold on itself in the contracted state, in the manner of a conventional drape.

Abstract: A data transmission system receiver is disclosed which receives a formatted data stream (302) and operates in one of at least a first bandwidth mode and a second bandwidth mode. The formatted data stream (302) comprises a plurality of data edges (108, 110) and is sampled by a first clock signal (320). A plurality of clock edges (102, 104) defining transitions from one logic state to another is used to define "early" and "late" data edge occurrences. These occurrences are accumulated in accumulators (310, 312) and used as inputs to a clock counter (318) which produces a phase-adjusted clock signal (320). Additionally, the data transmission receiver comprises a detector (330) for detecting when a limited data stream (306) is synchronized with the phase-adjusted clock signal (320) and, in accordance with a predetermined algorithm, is able to switch the phase-lock circuit from the first bandwidth mode to the second bandwidth mode.

Abstract: An improved method is disclosed for imparting a tint or color to a soft, hydrogel contact lens by uniformly dispersing a dye throughout the lens. The dye is a water-soluble halotriazine dye. The dye is reacted with a hydrophilic monomer to prepare a reactive dye containing predominantly monofunctionality. The monomer is then subjected to polymerization in the presence of a homogeneous solution of the reactive dye in the monomer under conditions to yield the hydrophilic polymer from which the lens is formed. The dye becomes bonded to the polymer during polymerization.        The finished lens does not require soaking in an aqueous solution of the dye to impart the desired tint or color to the lens. Additionally, the dye uniformly dispersed throughout the lens according to the improved method does not leach out of the lens or migrate within the lens.      Furthermore, the lens does not need to be washed with aqueous base to bond the dye to the lens.

Title: Propeller for boat
Inventor: NAKAZATO IKUO

Granted: 1998-06-30
Abstract: In a propeller for a boat,  a plurality of recesses and   a   plurality   of   land   portions   are   arranged circumferentially  alternately around  an outer  Periphery of a propeller boss which is fitted over and connected to a propeller shaft. A boss of each of propeller blades and each of blade shafts disposed parallel to an axis of the propeller boss to rotatably support such propeller blade are accommodated in each of the recesses, and each of the land  portions  is  provided  with  an  exhaust  passage extending axially through the land portion to permit an exhaust outlet  in a body of a propelling device  to be opened at a rear end face of the propeller boss. Thus, it is possible to discharge an exhaust gas  from an engine through the inside of the propeller boss  into water.  In addition,  an extension shaft  is  spline-fitted over  and detachably secured to a Protrusion of the propeller shaft projecting  rearwardly  of  the  body  of  the  propelling device  to  extend  rearwardly  from  a  rear  end of  the propeller  shaft.  The propeller  boss is  fitted over  the extension shaft over its substantially entire length. The propeller blade is mounted around an outer periphery of a front half of the propeller boss, 90 that the propeller diameter  or  pitch angle  can be varied,  while  a  damper rubber  is  baked  to  an outer  peripheral  surface  of  the extension shaft and press-fitted  into an annular  recess which is defined around an inner periphery of a rear half of  the  propeller  boss.  Thus,  a  variable-thrust  type propeller with a torque limiting device can be attached to a relatively short propeller  shaft used for  a usual propeller.

Abstract: Mercury is removed from a liquid hydrocarbon fraction by effecting high-temperature heat treatment to convert an organic mercury compound into an inorganic mercury compound or elemental mercury, removing a higher molecular weight component from the fraction, removing water from the fraction, and thereafter contacting the fraction with an adsorbent in the form of active carbon having calcium or a calcium compound supported thereon. Although only a minor amount of mercury is contained in the liquid hydrocarbon fraction, mercury can be efficiently removed at low cost on an industrial large scale, achieving an extremely low mercury concentration.
