Title: Automatic metering device for powdery bulk material, in particular coffee powder
Inventor: FREUND EDGAR
IPC: B65G65/48
Filed: 1995-02-22
Abstract: An automatic metering device for powdery bulk material, in particular coffee powder, has a reservoir (1) with a wall (2) and a stationary base plate (3) for the bulk material. The base plate (3) has an opening (4) to a conveyor tube (5) which is disposed below said plate and in which a conveyor member (6) is disposed for conveying the bulk mate-rial to a delivery location. According to the invention, the wall (2) of the cylin-drical reservoir (1) is rotated during the metering process, and a sensor is pro-vided for determining the amount to be delivered by the conveyor member. The appliance of the invention enables bulk material, in particular coffee powder, to be metered simply and accurately with-out the risk of bridges forming inside the reservoir such that the bulk material poured in first is also dispensed first.

Title: Liquid ejection method and liquid ejection head therefor
Inventor: OKAZAKI TAKESHI
IPC: B41J2/14
Filed: 1996-09-20
Abstract: A Liquid ejecting method for ejecting liquid using a bubble, includes using a liquid ejecting head having an ejection outlet for ejecting the liquid, a bubble generating region where a bubble is generated in the liquid, a movable member which is disposed faced to the bubble generating region, and which is displaceable between a first position and a second position farther from the bubble generating region than the first position and which has a free end at a downstream side thereof; displacing the movable member from the first position to the second position by pressure based on generation of the bubble in the bubble generating region, wherein the bubble expands more to the downstream side than to the upstream side with respect to a direction toward the ejection outlet by the displacement of the movable member, thus directing the bubble toward the ejection outlet to eject the liquid through the ejection outlet: and imparting an operation to the liquid ejecting head to normalize a state of the liquid in a liquid flow path for the liquid at least before liquid ejection start or at the time of non-ejection of the liquid.

Title: Polymerization reactor and process
Inventor: ZBORIL VACLAV GEORGE
IPC: C08F2/04
Filed: 1996-12-19
Abstract: A chemical reactor has an intensively mixed zone and a less intensively mixed zone together with a re-circulation loop to exchange reactants between the two zones. The reactor is suitable for reactions in which it is desirable to add a cold feed stream to the reactor without causing undue precipitation of the warmer reactor contents (and, accordingly, is especially suitable for the preparation of linear low density polyethylene by a solution process). The cold feed is intensively mixed with a portion of the hot reactor contents in the micromixed zone. The intensive mixing is sufficient to present precipitation. The resulting "warm" mixture is then circulated into the bulk of the hot reactor contents which are located in a reaction zone that is far less intensively mixed.

Title: Video switching system, video communications system and method for automatically establishing video communications using a telephonic switch
Inventor: DEZONNO ANTHONY J
IPC: H04N7/173
Filed: 1997-01-24
Abstract: A video switching system 108 automatically establishes video communications between an agent terminal 110 and a video communications device 104. A  telephonic switch, such as an automatic call distributor (ACD) 102, selects which agent terminal 110 receives the video communications and generates reports relating to the video communications. A programmable switch 105 receives an initial request from the video communications device 104 to establish video communications. A computer system detects the initial request and instructs the ACD 102 to select the agent terminal 110 which is to receive the video communications. The ACD 102 selects the agent terminal 110, or an agent associated with the agent terminal 110, using known methods and transmits the selected agent terminal 110 to the computer system 112. The computer system 112 instructs the programmable switch 105 to route the video communications to the selected agent terminal 110. When the ACD 102 receives the instructions to select the agent terminal 110, the ACD 102 begins to collect information relating to the video communications. The computer system 112 detects when the video communications has ended and notifies the ACD 102. In response, the ACD 102 stops collecting information, such as communication time, and makes the agent terminal 110 available.

Patent CA-2205542-A1 (CA)
Inventor: GOODING ROBERT W
IPC: G01N33/34
Filed: 1995-12-06
Abstract: A method and apparatus are described for continuously sampling a process stream, or reservoir of aqueous cellulosic pulp and detecting oversize contaminants in the sampled stream. This serves the overall objective of estimating the level of contamination in the process stream or reservoir during a given period of production; the method may include the following stages: 1) a continuous sample stream is drawn from the process or main stream, 2) the stream is passed through a centrifugal device which divides the sampled stream according to density, 3) the stream with the higher level of contaminants from the centrifugal device is passed to a screen which isolates the contaminants, and 4) the contaminants are flushed from the screen so that they can be quantified; these measurements are used to assess the purity of the material being produced. One useful application of this invention is to assess the presence of trace amounts of plastic contaminants in the production of the cellulosic pulp. Compared to manual methods for inspecting for plastic, this invention provides a measurement which is more accurate, more convenient, and less subjective.

Title: Synchronizer
Inventor: HIRAMATSU KATSUHIKO
IPC: H04J3/06
Filed: 1997-08-01
Abstract: A detection circuit of a synchronizer detects a difference between a reference timing of a transmitter and a reference timing of a receiver based on a time of receiving a known transmission pattern sent from the transmitter.  An average value calculation circuit calculates an average value of the difference detected by the detection circuit.  An integration circuit determines an integrated value by integrating the average value each time of interrupting the receiver.  A correction value calculation circuit calculates a correction value to correct the reference timing of the receiver in forward direction in the case where the integrated value exceeds a predetermined first threshold level and to correct the reference timing of the receiver backward in the case where the integrated value is reduced below a predetermined second threshold level.
