The system includes special forms of equipment for mixing and pressurizing the gas and air in the correct ratio and special forms of equipment for establishing and controlling the combustion processes.

Abstract: The energy conversion system disclosed is especially adapted for use with hydrocarbon or fossil fuels, for instance natural gas, with which substantial quantities of water vapor are developed when the fuel is burned, for instance in an engine, such as a turbine or a cylinder and piston internal combustion engine. In the system according to the present invention increased efficiencies are achieved by employment of a special form of power package capable of much more effectively utilizing the waste heat of the exhaust gases than has been practicable heretofore. The application also discloses tube-in-tube type of heat exchangers for use in the disclosed and also in other energy conversion or transfer systems.

Abstract: Method and apparatus are disclosed for forming fibers from attenuable materials, especially mineral materials such as glass, the disclosed technique including components providing for attenuation by toration, i.e., attenuation by delivering a stream of attenuable material in attenuable condition into the zone of interaction of a gaseous jet penetrating into a larger gaseous blast.

Abstract: Method and apparatus are disclosed for forming fibers from attenuable materials, especially mineral materials such as glass, the disclosed technique including components providing for attenuation by toration, i.e., attenuation by delivering a stream of attenuable material in attenuable condition into the zone of interaction of a gaseous jet penetrating into a larger gaseous blast. The blast, jet and means for delivery of the stream of attenuable material are disclosed in an interrelationship according to which the device for generating the blast is arranged to deliver the blast in a downwardly directed path, in which the means for generating the jet is arranged to deliver the jet laterally into the blast, in which the stream of attenuable material in attenuable condition is delivered downwardly from a delivery orifice in a position between the blast generating device and the jet generating means, and in which the orifices for both the jet and the attenuable material are spaced from the blast.

Abstract: Equipment is disclosed for gas blast attenuation of attenuable materials by the toration type of technique according to which a gaseous jet is directed transversely into a gaseous blast of larger cross section, thereby developing a zone of interaction of the jet and the blast into which a stream of the attenuable material is delivered. Each fiberizing center incorporates a plurality of components including means for generating the jet, means for generating the blast, and means for supplying the stream of attenuable material. In addition, the fiberizing center frequently also incorporates an additional structural element or means positioned along the path of the jet and influencing the jet flow.

Abstract: The complete drum comprises two, axially-separable, generally cylindrical sections, which are open, inwardly, toward each other, each of these two sections having but one playing head, so that the two heads are disposed respectively at the outer ends of the cylindrical assembly. When the open ends of these two basic sections are axially spaced-apart to provide an annular gap between them, the space within said sections communicates with the ambient air, through said gap, substantially uniformly around the periphery of the drum. This construction, with gap, is intended to provide any desired increase in volume, and a great variety of tonal modifications.Means are provided for adjustably varying the size of the gap, or for closing it altogether; whereby the volume, pitch, dynamics, and tonal characteristics of the drum may be varied. This may be done by using adjustable holding means, and/or by using perforate or imperforate cylindrical filler pieces.

Abstract: A machine, and method, for tumbling objects or parts, generally of plastic material, to remove thin flange-like projections left along mold mating lines and frequently referred to as "flash". An advancing belt-like conveyor has a portion disposed to define an object-supporting surface so upwardly sloped in the direction of conveyor advance, as to cause tumbling and consequent deflashing of a mass of objects supported on said surface. The conveyor is also movable between two positions in which the objects are, respectively, loaded upon and automatically discharged from the conveyor. In the illustrated apparatus these are upper and lower positions. Tumbling occurs in the upper position, and discharge takes place in the lower position, under the influence of the advancing movement of the conveyor. The system includes mechanism for effecting additional cleaning of the objects, while tumbling on the conveyor, by subjecting them to a blast of impact cleaning media.
