Abstract:
The present invention provides a pharmaceutical dry powder composition comprising (i) a compound of formula (I): or a salt or solvate thereof in solid particulate form; (ii) one or more pharmaceutically acceptable particulate carriers; and (iii) one or more stabilising excipients of potential use in the treatment of inflammatory diseases such as asthma and chronic obstructive pulmonary disease.
Abstract:
The present invention provides processes for preparing co-precipitates of non-crystalline, solid drug substances, such as (E)-4-(1,3-bis(cyclohexylmethyl)-1,2,3,6-tetrahydro-2,6-dioxo-9H-purin-8-yl)cinnamic acid nonaethylene glycol methyl ether ester and solvates thereof.
Abstract:
A smoke detector has a light sensor positioned such that a light-receiving surface of the sensor extends generally parallel to a light beam generated by a SMD LED light source of the smoke detector. The light sensor has an enclosure surrounding the light-receiving surface, which enclosure has an aperture in a side facing the light beam. The front and rear edges of the aperture (with reference to the direction of the light beam), are positioned to create a balance of sensitivity to forward-scattered pale-coloured smoke and backward-scattered dark-coloured smoke. The use of a SMD LED in. association with a proximate means for redirecting and refocusing light allows for construction of a compact low-profile smoke detector. The SMD LED may be a laser diode.

Abstract:
A herbicidal compound of formula (I) or a salt, tautomer or cyclic derivative thereof; where R and R are hydrogen and A is an optionally substituted saturated or unsaturated chain or ring of three carbon atoms. Methods for preparing these compounds, intermediates used in the preparation and herbicidal compositions containing them are also described and claimed.

Abstract:
A hazard detector has an electronic circuit with a start-up program for causing emission of a local indicator signal, such as a flashing signal from a LED, if power and ground terminals of the detector are connected with proper orientation, i.e. polarity, to power and ground lines of a power supply. Through this means, a person installing the hazard detector can tell immediately after connection if the detector has been connected with proper orientation, and avoids the need for introducing a hazard such as heat or smoke to test the operation of the detector. A variation uses a more sophisticated program that disables, during a test mode, complex filtering algorithms that are used by detectors to block false alarm signals; if such filtering is not disabled, impedes normal testing of the detectors.
