Abstract: A sensor clip for positioning a sensor relative to a substrate, particularly but not exclusively a temperature sensor (e.g. a thermocouple) used to obtain a temperature profile of a part of the substrate or surrounding environment as it passes through an industrial oven. The sensor clip comprises a first part and a second part slidably mounted with respect to the first part, the parts defining a pair of jaws having opposed surfaces for engaging sides of the substrate, with jaw separation being determined by linear movement of one part relative to the other.

Abstract: Thermally insulating apparatus for housing heat sensitive electronic apparatus, comprises an open-topped box with a detachable lid. A gasket is provided to form a heat seal between the open-topped container and the lid. At least one external surface of the gasket, which is exposed to ambient conditions when the lid is removed from the box, is unreactive to the extent whereby hydrophilic particles (e.g. dust) coming into contact therewith are not contaminated and made hydrophobic. The presence of hydrophobic particles may interfere with processes where the thermally insulating apparatus is deployed, and thus maintaining inherent hydrophilic properties may be important.
