Abstract: An improved fuel burning assembly particularly adapted for use with a boiler having a fire box situated below an array of boiler tubes. The assembly discharges a number of spaced rotating streams of minute droplets of a flowable fuel both laterally and longitudinally into the fire box to intermix with a stream of air that is moving rearwardly therein. The fuel air mixture when burning blankets substantially all the boiler tubes with a sheet of flame. Due to such flame contacts substantially all of the boiler tubes are heated uniformly thereby, rather than only a portion of the boiler tubes being contacted by the flame as occurs in a boiler when a conventional burner assembly is used. As a result of the flame distribution and uniform heating of the boiler tubes, an increased thermal efficiency is attained in the operation of the boiler on which the burner assembly of the present invention is used.

Abstract: An apparatus and method of using the same in which microwave energy transforms water in the form of finely divided droplets having a large aggregate surface area into pressurized steam. The method of the present invention has a high thermal and electrical efficiency, as the microwave energy impinges directly on the water droplets, and there is no loss of heat by conduction or convection.

Abstract: A power operated device for lifting first and second rolls of liner from the floor to elevated positions, and so rotatably supporting the rolls that they may be sequentially unwound and fed to a corregated paperboard making machine. As the liner of one of the rolls is being fed to the machine, the device may be pivoted to a position where a depleted roll may be removed therefrom and a new roll of liner mounted on the device. The device is also adapted to rotatably support two or more split rolls of liner to permit the liner to be concurrently fed to the corregated paperboard making machine.

Abstract: A device for use in separating magnetically attractable particles from a stream of liquid in which they are entrained, and segregating the separated particles in a confined space. The separated particles may be periodically discharged from the confined space into a suitable container without interrupting the flow of stream of liquid. A window in the device permits the user to visually observe the separated particles moving by gravity from the stream of liquid to the confined space.
