Title: Electronic interlock for electromagnetic contactor
Inventor: HURLEY RICK A
IPC: H01H47/04
Filed: 1994-02-24
Abstract: ELECTRONIC INTERLOCK FOR ELECTROMAGNETIC CONTACTOR             Abstract of the Disclosure An  electrical  contactor  has  first  and  second contacts movably mounted to engage for achieving continuity in an electrical circuit, via an electromagnet and armature defining a magnetic circuit with an air gap that closes in a first position of the contactor and opens in a second position  of  the  contactor.    A  controller  switches  an alternating current voltage to the coil of the electromagnet during a times portion of each AC half cycle, and senses the current  level  in  the  coil  in  a  feedback  loop.    The controller  adjusts  the  voltage-on  time  to  achieve  a predetermined average current as needed for accelerating the armature or coasting during a closing operation, for holding the armature in place when closed, etc.  In order to sense whether the contactor is presently open or closed,  the controller monitors and stores the phase angle between the previous voltage zero crossing and the time of voltage turn-on.  When the inductance of the magnetic circuit including the  electromagnet  and  armature  changes  rapidly  due  to opening  or  closing  of  the air  gap  between  them,  the controller detects a corresponding variation in the phase angle.   The controller  is preferably a microprocessor, programmed to normalize the phase angle over a range of coil drive voltages.   The microprocessors of a number of such contactors can communicate in order to effect coordinated operations.

Patent CA-2127307-A1 (CA)
Title: Beverage server
Inventor: PATEL DAHYABHAI U
IPC: A47J41/00
Filed: 1994-07-04
Abstract: A beverage server includes a body having an internal reservoir to hold a beverage such as hot coffee. In one embodiment, a lid is pivotally connected to the top of the body. The lid has a generally conical passage provided through it which permits a beverage to enter the beverage server and pass into the reservoir without requiring removal of the lid. A floatable ball is located within the passage to seal it when no liquid is entering the beverage server. A pouring spout extends from the body near its top and is in fluid communication with the reservoir when the beverage server is tilted and the lid pivots. A counter-weight in the lid assists in bringing the lid into sealing engagement with the body to isolate the pouring spout and the reservoir when the beverage server is upright. The counter-weight also assists in smooth motion of the lid as it pivots through its entire range of movement when the beverage server is tilted.

Patent CA-2136896-A1 (CA)
Inventor: NAKAYA KAZUYOSHI
IPC: H04L1/00
Filed: 1994-11-29
Abstract: A framing and voice decoder part outputs an error information. An error ratio monitoring part monitors a bit error ratio based on the error information. A sampling rate changing part decides a sampling rate based on the bit error ratio and changes a number of bits of each shift register in the differential detector part to adapt the sampling rate. A sampling clock selector part selects one clock signal among four different frequency clock signals based on the decision of the sampling rate changing part and gives selected clock signal to the differential detector part as a sampling clock.      The differential detector part makes demodulation in DQPSK (Differential Quadrilateral Phase Shift Keying). Since the error ratio is always maintained within a predetermined extent, a good voice quality is obtained. Since the sampling rate will not increase to unnecessarily high levels, power saving can be achieved and a consumption of batteries is reduced.

Title: Wireless local radio link telecommunications apparatus
Inventor: CHENG TERRY SI-FONG
IPC: H04W84/10
Filed: 1995-07-19
Abstract: A wireless local radio link apparatus providing a communications  interface  between  a  telecommunications network and a network subscriber includes separate base and handset units that are in radio communication with one another during periods of use.  Each unit includes transmit circuitry that converts incoming communications signals into radio frequency signals which are then broadcast to the other unit,  and receive  circuitry  that  converts  radio frequency  signals  received  from  the  other  unit  into appropriate outgoing communications signals.  The quality and recoverability of the outgoing signals of at least one of the units, preferably the base station, is enhanced by providing the other unit with redundant transmit circuits each broadcasting through a different one of physically spaced  antennas  for  providing  path  diversity  in  the respectively transmitted signals.  In addition, a time delay is imposed on the radio frequency signal broadcast through one antenna relative to that broadcast by the other antenna of the enhanced unit to thereby provide time diversity between the radio frequency signals traveling along the different paths from the respective antennae of the enhanced unit to the other unit.  The magnitude of the imposed time delay is at least equal to that required for the receive circuitry of the other unit to separately and individually convert the received radio frequency signals for subsequent combination.
