Patent CA-2128725-A1 (CA)
Title: Combinaiton faucet and method of mixing hot water with cold water
Inventor: EKI TOSHIO
IPC: G05D23/13
Filed: 1993-11-22
Abstract: ABSTRACT OF THE DISCLOSURE    The present invention provides  a combination faucet which compensates for a temperature deviation of an actual temperature of water mixture from a target temperature by pressing a movable valve disc (70) for determining a mixing ratio of hot water to cold water with a temperature-sensitive coil spring  (80).   The temperature-sensitive coil spring (80) is composed of such a material that varies a spring constant  of  the  temperature-sensitive  coil   spring  (80) according to a temperature change.   When the temperature control only by the temperature-sensitive coil spring (80) can not sufficiently compensate for the temperature deviation, feed-back control is executed for completely eliminating the temperature deviation.   A control gain K of the feed-back control is determined according to a variation of the spring constant of the temperature-sensitive coil spring (80) for preventing an undesirable hunting.   When the temperature deviation  is  eliminated  by  the feed-back  control,  the relationship between a target temperature and a current pre-load adjustment quantity is stored. The stored relationship is used to determine a pre-load adjustment quantity when the same target temperature is set. At a start of spouting water mixture or on a variation of the target temperature, the feed-back control is not executed until the temperature deviation becomes smaller than a threshold value TR1.  This effectively prevents hot water from abruptly spouting after completion of spouting dead water.

Title: Motor Control System and Components Thereof
Inventor: OWEN DONALD W
IPC: H02K5/04
Filed: 1991-09-11
Abstract: A motor control system includes a single, multicompartment enclosure mounted on a skid.  The enclosure contains a transformer circuit and a motor controller circuit interconnected so that only external connections to a power source and a load are needed.   When the circuits are energized, access to high voltage motor control components and to field replaceable fuses and output selection switches is prevented by a double interlocking mechanism which operates in conjunction with energizing and de-energizing the transformer. The transformer of the transformer circuit includes a tertiary winding disposed radially between a primary winding and a secondary winding.  The winding filters electrostatically coupled  transients.    A  conventional  electrostatic shield  is  also  used  so  that  the  transformer  is  doubly shielded to electrostatic transients.  The tertiary winding is connected to one or more capacitors to filter magnetically coupled transients.   A current limiting fuse, a load sensing fuse and a primary make/break switch are connected in electrical series to the primary winding.  Methods for energizing or operating a motor utilizing the primary switch and the load sensing fuse are also disclosed.
