Abstract: A toggle clamp assembly for a flexible hose includes a flexible strap having a friction grip buckle for securing the ends of the strap into a loop around a hose and a toggle lever having one end attached to the strap and adapted to pivot from a non-tensioning position to a tensioning position for applying tension to the strap for clamping it about a flexible hose. The toggle lever includes a slot for receiving a twist fastener for fastening or holding the lever in the tensioning position.

Abstract: A fluidized bed coal reactor includes a combination nozzle-injector ash-removal unit formed by a grid of closely spaced open channels, each containing a worm screw conveyor, which function as continuous ash removal troughs. A pressurized air-coal mixture is introduced below the unit and is injected through the elongated nozzles formed by the spaces between the channels. The ash build-up in the troughs protects the worm screw conveyors as does the cooling action of the injected mixture. The ash layer and the pressure from the injectors support a fluidized flame holder combustion zone above the grid which heats water in boiler tubes disposed within and/or above the combustion zone and/or within the walls of the reactor.
