A cleaning appliance includes a main body, a filter and an interlock. The main body includes an airflow generator, a separating apparatus separating dirt and dust from an airflow, and a flowpath between the separating apparatus and the airflow generator delimited by a wall. The interlock has a first part located on the filter and a second part located on the main body outside the flowpath, arranged to communicate remotely when the filter is correctly located in the pre-determined position. The interlock is arranged selectively to allow or prevent operation of the airflow generator depending upon the relative separation between the first and second parts. By providing an interlock which has first and second parts which communicate remotely, the second part located on the main body can be isolated from the airflow path so that the second part is not subject to dirt and dust carried by the airflow.

A leadless plastic chip carrier is constructed by half etching one or both sides of the package design onto a leadframe strip so as to create unique design features such as power and/or ground ring surrounding the die attach pad, interlocking rivet head construction for the contact pads, and an interlocking pattern for the die attach pad. After wire bonding and molding, a further etching is performed to isolate and expose contact pads. Singulation of individual chip packages from the leadframe strip is then performed by saw singulation or die punching.

A direct fastening fastener particularly suited for use in normal weight or lightweight composite deck system. The fastener is heat treated to a dual-hardness level so that a portion of the fastener is capable of driving into the support member, such as a joist and a decking member. The remaining portion of the fastener remains relatively ductile so that it can withstand and transfer shear loads imposed by shifting of the concrete slab, which overlies the composite decking, to the support member. The fastener can be a single or multiple piece fastener which includes specially formed annular flanges that enhance interlocking between the fastener, the concrete slab and support members.
