Patent CA-2136894-C (CA)
Title: Miniaturized superconducting dielectric resonator filters and method of operation thereof
Inventor: MANSOUR RAAFAT R
IPC: H01P1/208
Filed: 1994-11-29
Granted: 1997-05-20
Abstract: An improved design for microwave bandpass cavity filters wherein dielectric resonator elements are mounted in dielectric blocks (there can be more than one resonator element per dielectric block).  The dielectric blocks are in turn fitted within the filter housing, and the open ends are covered by shorting plates which are maintained in contact with each resonator surface.  The shorting plates may be coated with a superconductive material.  The structure results in significant size reduction over prior art filters.  In addition, the new design is of higher structural integrity and helps to maintain a consistent output over a wide range of temperatures. By carefully choosing the dielectric materials to insure uniform thermal expansion of the component parts, the filter output is stable over a wide range of temperatures.  This allows the filters to be tuned while at cryogenic temperatures, then returned to room temperature for storage or shipping, and finally return to cryogenic temperatures for operating purposes.  The filters can be constructed with various configurations and can be operated in single mode, dual-mode, triple-mode, etc.

Abstract: A locking structure for a valve of the type where the valve member is turned less than 360 degrees between fully open and fully closed positions as, for example,  a ball valve.  This structure employs a stop pin on the valve body positioned to be engaged by the handle of the valve in the fully open and closed positions of the valve.  A lock plate structure is journaled on the valve stem and is arranged to engage the opposite side of the stop pin from the handle in the fully open and fully closed positions of the valve, such that when a lock is secured in mating apertures in the lock plate and the handle, the valve will be securely locked in either a fully open or fully closed position.

Title: Delivery device for injectable materials
Inventor: KURJAN CHRISTINE M
IPC: A61M5/142
Filed: 1995-04-28
Granted: 2000-02-29
Abstract: The invention pertains to a delivery device for controlling the injection of discrete quantities of fluid injectable materials through a conduit such as a hypodermic needle or a catheter. The delivery device is coupled to a pressurized driving fluid source, and the control means provides controlled passage of pressurized driving fluid into a syringe body to act against a piston which forces the fluid injectable material out the needle or catheter. In addition to the delivery device, the invention includes a needle depth guide which is preferably used in combination with the delivery device for cosmetic applications when a hypodermic needle is used to deliver a fluid injectable material to the dermis.

Title: Transmission power control method and apparatus for mobile communications using a cdma (code division multiple access) system
Inventor: DOHI TOMOHIRO
IPC: H04W52/00
Filed: 1995-05-17
Granted: 1999-01-26
Abstract: A transmission power control method for controlling transmission power of radio communications in a CDMA system.          The transmission power of a first transmitted signal transmitted from a first station is determined by a transmission power control signal contained in a second transmitted signal sent from a second station.  The first station receives the second transmitted signal in the form of convolutional codes, and decodes it by using a first Viterbi decoder and a second Viterbi decoder.  The first Viterbi decoder includes a path memory with the path history length of a first predetermined length, and the second Viterbi decoder includes a path memory with the path history length of a second predetermined length which is shorter than the first predetermined length.  The transmission power control signal contained in the second transmitted signal is extracted from the output of the second Viterbi decoder, whereas the other information data is obtained from the output of the first Viterbi decoder.  The first station controls the transmission power of the first transmitted signal on the basis of the extracted transmission power control signal.  This makes it possible to achieve highly accurate, fast responsive transmission power control.

Title: Portable communication device
Inventor: KUKI HIKARU
IPC: H04W28/00
Filed: 1996-05-07
Granted: 2000-04-25
Abstract: A portable communication device has a software processing section and a hardware processing section which are capable of performing wireless voice communication and wireless data communication of different communication modes and communication channels, wherein the portable communication device automatically matches the communication device of the portable communication device and the communication device of the opposite party before the communication is started. The transmitting side of the communication requests switching of the present communication mode or communication channel of the opposite side through a data signal so that the two sides use the same communication mode or communication channel. The transmitting side, thereafter, switches to the wireless voice communication and calls out. The receiving side of the communication switches to the wireless voice communication in accordance with the switching request signal transmitted from the transmitting side, thereby enabling voice communication.

Granted: 2007-08-07
Abstract: A method of regulating the temperature in a chemical melt dissolving tank, where chemical melt produced in combustion of spent liquor of a cellulose pulp mill is dissolved in liquid, producing green liquor, provides excellent heat economy, while minimizing the amount of liquid needed to dissolve the melt to produce green liquor at a temperature below boiling.  Green liquor produced in the dissolving tank is expanded (and thereby cooled) in a vacuum tank, and at least a significant part of the cooled liquor is returned to the dissolving tank, for regulating the temperature in the tank. The heat energy contained in the generated expansion steam may be used in many different ways, for example, for indirectly heating (e.g. in a heat exchanger acting as a condenser) water or other liquid to a sufficiently high temperature so that the liquid is useful elsewhere in the pulp mill. The vacuum tank may be positioned above the dissolving tank to receive liquor directly from it, and the condenser may be positioned in it to return condensate directly to the dissolving tank.  Alternatively the vacuum tank and condenser may be remote from the dissolving tank and connected to the dissolving tank by a conduit.

Abstract: An apparatus for providing local programming with direct broadcast satellite transmission includes a terrestrial transmitter (14) for transmitting converted local channel signals in a first frequency band. The first frequency band is contained within a satellite broadcast frequency band in which the direct broadcast satellite channels are transmitted. The apparatus also includes at each user or subscriber location, a first antenna (34) for receiving the converted local channel signals from the terrestrial transmitter and a second antenna (38) for receiving a direct broadcast satellite channel signals from the satellite. The apparatus further includes a combiner (44) for combining the converted local channel signals and the direct broadcast satellite channel signals on a single propagation path. A signal processor/decoder (18) processes the combined signals on the single propagation path to produce a desired channel output to drive a television set (20). To the processor/decoder (18) the combined channel signal appears as if it had been all broadcast directly from the satellite. Therefore, the apparatus requires no additional receiver for receiving local programming along with regional and national programming provided by satellite transmission.
