Abstract: The strainer arrangement is adapted for straining a liquid from a mixing arrangement, such as a mixing tank, containing black liquor including solid particles of ash. The strainer arrangement comprises a strainer pipe with axial gaps defined therein for permitting a radial inflow of liquid into the strainer pipe. An axially movable shaft is disposed inside the strainer pipe and has cleaning pins attached thereto that extend into the gaps.

Abstract: Improved tape assemblies for delivering electrical devices to work stations at which the devices are installed. Each of the devices comprises a laminar electrical component sandwiched between two laminar metal members, and is preferably a PTC circuit protection device. In the assemblies, the electrical components are discrete components, but they are contacted by, and linked together through, laminar metal members which, after the assembly has been divided into separate devices, provide leads which contact and extend away from the electrical component. Preferably the metal members are prepared by cutting and forming a single strip of metal. Preferably the assembly is free from any longitudinally continuous carrier strip which much be discarded after the devices have been separated from each other. Preferably, the assemblies are sufficiently flexible to be wrapped around a reel and unwrapped at the work station.
