Inventor: CLARKE ALASTAIR ROBERT
IPC: B65D/
Filed: 1998-10-23
Granted: 2007-05-08
Abstract: An inhalation device which contains powdered medicament in the form of a medicament compact is provided with a seal comprising a partial ring between the outer wall and inner mandrel of the medicament compact chamber. The medicament is dispensed by abrading the medicament compact by turning the compact relative to the inner mandrel against a blade. Despite only extending around part of the circumference of the mandrel the seal prevents leakage of loose powder from the compact chamber to the rest of the device. The sealing means also provides a frictional braking force on the medicament reservoir sufficent to prevent movement of the medicament reservoir when the drive mechanism for the reservoir is returning to its starting position without making the device difficult to operate by a child or infirm adult.

Title: Noise cancellation circuit and quadrature downconverter
Inventor: MATHE LENNART KARL-AXEL
IPC: H03H7/12
Filed: 1999-01-11
Granted: 2008-03-18
Abstract: A noise cancellation circuit and quadrature downconverter for use in conjunction with a bandpass receiver. The noise cancellation comprises at least one bandpass decimator and a summer. The output from each loop of a sigma-delta analog-to-digital converter (.SIGMA..DELTA.  ADC) is provided to a respective bandpass decimator. Each bandpass decimator comprises an error cancellation filter, a bandpass filter, and a decimator. The transfer functions of the error cancellation filter and bandpass filter are convolved to provide the transfer function of the bandpass decimator. The filtered signal is then decimated by N. The decimation by N can be incorporated within the bandpass decimator such that the bandpass decimator operates at 1/N of the frequency of the ADC  sampling clock. The signals from all bandpass decimators are summed together and the resultant IF samples are provided to two multipliers which downconvert the IF samples to I and Q baseband samples with an inphase and a quadrature sinusoid, respectively. The baseband samples are lowpass filtered to further remove quantization noise and undesirable signals. The center frequency of the analog input signal, the ADC sampling clock, and the decimation by N can be selected such that an image of the input signal appears at 0.25f s, where f s is the sample rate of the decimated samples.

Title: Positron emission tomography using gallium-68 chelates
Inventor: GRIFFITHS GARY L
IPC: A61K51/00
Filed: 1999-05-06
Granted: 2007-07-24
Abstract: A method of delivering Ga-68 to a target site is effected by administering a bi-specific antibody which specifically binds via a primary binding site to a substance produced by or associated with the targe t site and which specifically binds via a secondary binding site to a subsequently administered chelate-Ga-68 complex, and allowing the antibody to localize at the target site; optionally administering a clearing agent to clear non-localized bi-specific antibody rapidly from circulation; and administering a chelate-Ga-68 complex comprising Ga-68 chelated to Ac-Phe-Lys(DTPA)-Tyr-Lys(DTPA)-NH2 and allowing the chelat e- Ga-68 complex to localize at the target site via specific binding by the secondary binding site of the bi-specific antibody. The targeted complex then can be used for PET imaging to give highly resolved images. Alternatively, the Ac-Phe-Lys(DTPA)-Tyr-Lys(DTPA)-NH 2 can be conjugated to a targeting antibody fragment and used to elute Ga-68 from a generator, after which it is infused into a patient for direct targeting of the Ga-68 for PET imaging. Reagents and methods of making and using them also are provided.

Abstract: A particulate filter (22) carrying an active oxygen release agent which takes in oxygen and holds oxygen when excess oxygen is present in the surroundings and releases the held oxygen in the form of active oxygen when the concentration of oxygen in the surroundings falls is arranged in an exhaust passage of an engine. The air-fuel ratio of the exhaust gas flowing into the particulate filter (22) is normally maintained lean and is occasionally switched to rich temporarily. When the air-fuel ratio of the exhaust gas is switched to rich, an oxidation reaction of the particulate on the particulate filter is promoted by the active oxygen released from the active oxygen release agent. Due to this, the particulate in the exhaust gas is continuously removed by oxidation on the particulate filter (22) without emitting a luminous flame.

Abstract: The invention provides a method, data processing system and software for processing control messages constructed in accordance with a first communications protocol for use in a communications network. Each control message includes a first address identifier having a format defined by the first protocol. The method comprises the step of processing said control message to derive a second address identifier from said first identifier, said second identifier having a format defined by a second communications protocol; and, the step of reformatting said control message for transmission, in accordance with said second protocol, to a network system associated with said second address identifier. The first communications protocol may be Session Initiation Protocol (SIP) and the second communication protocol Simple Mail Transfer Protocol (SMTP). The invention allows messages to be readily processed and diverted from a SIP defined destination URL address identifier to a corresponding SMTP defined destination URL address identifier for the same user or end system. In this way users may send SIP messages to SMTP address identifiers using the SMTP network protocol and infrastructure (416) and SMTP messages to SIP address identifiers using the SIP network protocol and infrastructure (408, 410, 412).
