Title: Transceiver operating in time division full duplex spread spectrum communication
Inventor: KOH HYUNG
IPC: H04B1/56
Filed: 1997-06-30
Abstract: A transceiver for direct conversion time division full duplex spread spectrum communication is described. It includes an antenna, 110 a time division duplexer 112 which couples the antenna to a transmission path or a receiving path of the transceiver in respective time intervals and a PLL 230 for generating an oscillation signal. The receiving path comprises a phase shifter 232 which phase shifts the oscillation signal by 90 degrees to provide a phase shifted oscillation signal. A first frequency mixer 226 generates a first base band signal by synthesising the oscillation frequency with a signal received from the time division duplexer 112 and a second frequency mixer 228 generates a second base band signal by synthesising the phase shifted oscillation frequency with the signal received from the time division duplexer 112. A demodulator 238 outputs pseudo noise data by decoding the first and second base band signals. The transmitting path includes a third frequency mixer 242 which provides to the time division duplexer 112 a modulated transmission signal by synthesising incoming pseudo noise data with the oscillation frequency or the phase shifted oscillation frequency.

Patent GB-2326215-A (GB)
Title: Hydraulic valves and systems
Inventor: SEDDON DONALD
IPC: G05D16/20
Filed: 1998-05-15
Abstract: An hydraulic valve 1 has a flow/pressure characteristic matched to that of a pump 40 with which it is used. The valve has a housing 10 with a fluid inlet 14 in its side and an outlet 13 at one end. A shuttle 15 is movable along the housing 10 under control of a proportional solenoid 100, to vary the amount by which an edge 30 of the shuttle covers the inlet 14 and thereby controls flow of fluid through the valve. The shuttle 15 has a flange 31 at one end located between the inlet 14 and outlet 13 so that fluid flowing from the inlet to the outlet applies pressure to one side 32 of the flange and displaces the shuttle to close the inlet. In this way, an increase in pressure tends to reduce the effective size of the inlet aperture 14 to compensate for pressure variation.

Title: Method and tool for generating and displayin a descriptive annotation of selec ted application data
Inventor: ENGLEFIELD PAUL JONATHAN
IPC: G06F9/44
Filed: 1998-07-24
Abstract: A set of software components, a system and a method provide to a user of a data processing system per-value interpretative information relating to application data values. The method includes the following steps: in response to user selection of a set of an application component's data values, generating per-value interpretation information corresponding to the selected data values; and, in response to subsequent movement of an input device pointer into a display screen area associated with a data value within the set, presenting the interpretation information to the user via an output device connected to the data processing system. A processing component selectable by the user from set of processing components preferably responds to user selection of both the operation to be performed and a set of application data by performing the processing operation on the set of data to produce a result, and then generating per-value interpretation information corresponding to that result. The presentation of interpretation information to the user preferably uses a flyover text box in a GUI, as is known in the art for application-specific Bubble Help.
Patent GB-2329257-A (GB)
Title: A method of operating a coating apparatus and a measurement apparatus therefor
Inventor: HOFER HANS-HERBERT
IPC: G01F22/02
Filed: 1998-09-07
Abstract: During the application of a coating material to paper or to cardboard, air inclusions in the coating material can interfere with production in various ways. It is proposed to measure the air inclusion content in a coating material by taking samples of the material. Each sample is introduced at a predetermined first pressure (p1) into a measurement cell 11 which has a closed first volume (V1). This closed first volume (V1) is then reduced to a closed second volume (V2) at which a predetermined second pressure (p2) that is greater than the first pressure (p1) prevails in the measurement cell 11. The air inclusion content of the coating material can then be derived from the change in volume (V1 - V2) required to produce the predetermined pressure change (p2 - p1). On the basis of the measured values, degassing equipment 9 can be optimally adjusted.
