Abstract: An electrochemical gas sensor is self-diagnosed on the basis of an output waveform that is generated when a power source of said gas sensor is turned on after said power source has been turned off for a short time and an output waveform that is generated when said power source is turned on after said power source has been turned off for a long time. In a normal gas sensor, when the power source is turned on after the power source has been turned off for the short time, a bottom will be generated in the potential of the sensing electrode side, and when the power source is turned on after the power source has been turned off for the long time, a peak will be generated in the potential of the sensing electrode side. A self-diagnosis of the electrochemical gas sensor can be done without pulse power source for self-diagnosis, and the dead time from self-diagnosis until start of detection can be shortened.

Abstract: A tube support device comprises an elongated strip inserted in a tube lane between the tubes of the tube bundle. Raised-tube-engaging zones are disposed in transverse rows across the strip at successive longitudinal locations along its length; these tube-engaging zones extend laterally outwards from both faces of the strip to engage with tubes on opposite sides of the tube lane. The tube-engaging zones may be arranged so that they extend from the two faces of the strip in an alternate manner, with the tube-engaging zones in each row alternately extending from one face and then from the other along the row.

Abstract: A method of filling a natural hollow elongated casing with meat emulsion involves placing a natural casing on an elongated meat emulsion stuffing tube having a meat emulsion discharge end, closing an extended end of the natural casing over the discharge end of the stuffing tube so that meat emulsion exiting the discharge end will push the natural casing longitudinally by pumping meat emulsion through the stuffing tube for expansive discharge into the natural casing at a sufficient volume and velocity to provide the primary energy within the natural casing to move the natural casing forwardly off of the discharge end of the stuffing tube. The casing is extended through a hollow chuck (100). A resilient brake element (160) in the chuck is extended around the casing to impede its longitudinal movement. A thrust collar (200) is slidably mounted on the stuffing tube and is intermittently manually pushed against the casing to limit the length thereof but is insufficient to create compression pressure thereon.

Abstract: A hand-held, fleet deployable infrared camera with integrated hardware and software providing real time processing of infrared images. The camera senses variable temperature images over a selected object of interest and senses variable emissivities over the object. The camera also measures and corrects for reflected environmental radiation as well as corrections for the atmospheric path through which the object is viewed. A calibrated reference patch having known emissivity and reflectance is attached to an object of interest and viewed through the camera. The calibrated patch is used to provide correction for the environmental radiation reflected off the object. Once the environmental radiation correction is known, it can be used to correct measurements taken from the rest of the object of interest.

Abstract: The invention relates to apparatus and methods for forming a terminal on a battery. Terminal forming apparatus (11) has a mould (12) with a cavity (26) which is intended to encircle the post and bush assembly (22, 25) of a battery box (10). The mould cavity (26) is formed with an open upper mouth (27) and a lateral inlet/outlet (28) which connects with the feed channel (13). Inlet (28) is defined by a weir (29) which acts as a constant height device to define the final filling height of the mould cavity (26). This arrangement allows over filling of the mould above the height of the weir (29) and subsequent dropping of that level to the height of the weir (29). This enables the terminal to be formed at precisely the correct height without the need for any metering of the lead.
