Abstract: A vacuum cleaning machine has a cannister with an inlet port and at least two outlet ports. At least two filters are disposed inside of the cannister, one in pneumatic communication through each of the outlet ports. At least two valves are disposed outside of the cannister. Each valve is in pneumatic communication between a vacuum source and an outlet port so as to permit air to be drawn by the vacuum source from the inlet port simultaneously through the filters. A controller operates the valves to switch the filters from the vacuum source to ambient air so as to permit ambient air to be sequentially intermittently drawn through corresponding valves and filters into the cannister. Preferably, the controller includes a timing mechanism for setting the delay time of the sequential valve operation and a timing mechanism for setting the intermittent time of connection of each filter to ambient air.

Abstract: A head of an open ended ratchet features outer face plates with voids that delimit a jaw space that is open at one end. Two gripping pieces face toward one another from opposing sides of the jaw space. A working side of each gripping piece features two working faces that lie at an oblique angle to one another to define an inner corner that fits over a respective outer corner of a fastener. The gripping pieces are displaceable along the plates into working positions reaching further into the jaw space. A force member is slidable along the plates to force the gripping pieces into the working position, in which the working faces frictionally engage peripheral faces of the fastener. A handle coupled to the head is pivotally movable in opposing directions to push and release the force member, thereby controlling engagement and release of the gripping pieces with the fastener.
