Abstract:
A combined muffler and heat exchanger apparatus is provided. The apparatus includes a housing defining a heat transfer chamber and an acoustic attenuation chamber separated by a partition. A flow regulator and a fluid transport member are disposed within the heat transfer chamber. The flow regulator is adapted to regulate the flow of a first fluid, such as a heat source, between an input end of the housing and the partition. The fluid transport member is adapted to contain the flow of a second fluid. An acoustic regulator is disposed in the acoustic attenuation chamber and extends longitudinally from the partition to an output end of the housing. The acoustic regulator is a metal tube including a plurality of apertures adapted to attenuate exhaust stream acoustics associated with an automotive vehicle power source.
Abstract:
A pattern implementation technique in which a pattern is defined as a software artifact that comprises a pattern signature representing one or more parameters of the pattern and a pattern implementation model representing one or more methods for expanding the pattern in a selected software context by assigning one or more arguments to the one or more parameters. The pattern implementation model can be based on one or more framework code sets, each of which supports the creation of plural patterns by providing a pattern implementation model for a particular software context. The framework code sets can be rendered extensible by a pattern author by virtue of providing methods whose code is adapted to be modified by a pattern author when defining a pattern. The pattern can be applied by creating an instance of the pattern in a software context and presenting a graphical representation of the pattern instance that can be manipulated by the pattern user in order to apply arguments to the pattern parameters.
Abstract:
The present invention provides a process for adhering a liquid to a particulate substrate. The process comprises the steps of:a) providing an apparatus which can create an oscillating magnetic field within a chamber,b) providing particulate magnetic material within the chamber of said apparatus while said oscillating field is active,c) having in the chamber within the oscillating magnetic field a liquid coating material and a particulate substrate to be coated with said liquid,d) and having said magnetic field form a fluidized bed of at least said particulate magnetic material, said liquid coating material coating the surface of the particulate substrate, ande) optionally continuously collecting the coated particulate substrate.The particulate magnetic material may be added to the chamber before or after the magnetic field has been activated to oscillate. The field may be active when the magnetic particles are added, and the field may be activated only after the magnetic particles are present as a non-fluidized sedentary bed. The liquid may likewise be added at any time. The liquid coating material may be added before the field is activated, or after the field is activated. The liquid may be added before the magnetic particles are added, at the same time or after the magnetic particles are added. The magnetic particles may provide the only particulate surface onto which the liquid is to be coated, or separate particulates may be used along with the magnetic particulate materials. The magnetic particulates may be included along with the non-magnetic particulates in the final desired product, or the coated magnetic particles may be easily separated from the non-magnetic particles by magnetic filtering or screening. This process provides a significant benefit in a liquid coating process by reducing the potential for waste and allowing easy recycling of coating material.
