Title: Quantitative powder feeder
Inventor: KIKUCHI YOSHIAKI
IPC: B65G65/48
Filed: 1996-09-06
Abstract: A rotor 22 accommodated in a casing 26 has a circumferential surface sliding on the internal surface of the casing 26 in airtight condition.  The casing 26 is provided with a powder feed part 27 positioned above the rotor and is provided with a powder drop part 30 positioned under the rotor.  At least one quantity-measuring recessed part is formed in the slide surface of the rotor.  In accordance with the rotation of the rotor, the quantity-measuring recessed part comes to communicate with the powder feed part, so that powder is fed from the powder feed part into the quantity-measuring recessed part.  When the rotation is advanced, the quantity-measuring recessed part comes to communicate with the powder drop part, so that the powder drops from the quantity-measuring recessed part through the powder drop part into a high-pressure part 19 arranged thereunder.  These members construct a quantitative powder feeder which, even when a pressure difference exists between the supply side and the supplied side, can effectively prevent the gas flow and pressure leak therebetween and can minimize the amount of carrier gas used for feeding powder.
Patent CA-2189077-A1 (CA)
Inventor: NEWTON RICHARD W
IPC: F25B1/04
Filed: 1996-10-29
Abstract: A vapor compression heat pump system comprising a lower temperature heat exchanger, a higher temperature heat exchanger and a compression path control (CPC) system.  The CPC system increases the coefficient of performance (COP) obtainable with some refrigerants, the environmentally benign refrigerant 718 (water) being an outstanding example.  This is achieved by the controlled alteration of the quality of the suction vapor prior to compression so that the resulting path of compression entails a reduced work requirement relative to the refrigerating effect obtained.  When the system is employed with refrigerant 718 (water) the resulting COP is higher than those of the halo carbon refrigerants currently scheduled for phase out by international agreement.  Thus it offers improved performance as well as security against any future restrictions due to refrigerant environmental effects.  The heat pump system can be used for heating or cooling or simultaneous heating and cooling; e.g., air conditioning and water heating.  It is also readily adaptable to variable compression ratio operation, such as that which would result from providing the higher temperature heat exchanger with the capability of switching between sinks at different temperatures.

Title: Apparatus and method for limiting jitter in a telecommunications signal
Inventor: NG TAT K
IPC: H04J3/06
Filed: 1995-06-02
Abstract: In a system where jitter in a first telecommunications signal (e.g., TUG-3) which is being mapped into a second telecommunications signal (e.g., STS-3C) is reduced by moving the TUG-3 pointer in the opposite direction of the pointer movement of STS-3C signal, the improvement is in suspending FIFO  measurement (504) from the time of the STS-3C pointer movement until the next TUG-3 stuff or destuff, and in further limiting jitter by moving the measurement points for the TUG-3 FIFO measurements without conducting TUG-3 pointer movements when the TUG-3 pointer movement would otherwise be moved into or over the transport overhead of the TUG-3 signal. The TUG-3 pointer movement is held in abeyance until two additional pointer movements in the same direction are received, and then the jump is made.
Patent CA-2193511-A1 (CA)
Title: Non-transparent data transmission in a digital telecommunications system
Inventor: KANERVA MIKKO
IPC: H04L29/08
Filed: 1996-05-08
Abstract: The invention relates to a digital telecommunications system, and particularly a method for non-transparent data tranmission. There is a non-transparent data connection (V.110+L2R/RLP) between a transmitting party (A) and a receiving party (B), on which channel coding is employed. The transmission buffer buffers the data frames to be transmitted and stores the transmitted data frames until it receives an acknowledgement of successful reception. In accordance with the invention, this is avoided by monitoring the quality of the non-transparent connection, and if the quality of the connection drops to a specific threshold value, by changing the channel coding scheme of the connection for a more efficient one. Simultaneously, however, more channel capacity is allocated for the connection in according with the chosen channel coding scheme so that the original nominal user data rate can be maintained unchanged or nearly unchanged.
