Hardware design

Generally, aerosol packaging consists of many dehcately balanced variables. Even hardware design plays an important part. For example, valves that produce considerable breakup are used for the warm sensation desired in some personal products. 

There are, of course, many more aspects of composite hardware design that differ from metallic bonded structure but do not necessarily involve adhesive bonding. For instance there are many types of reinforcement tape and fabric to choose from, the orientation of the plies must be chosen, the ply stackups must be balanced to avoid part warping after cure, a minimum number of plies must be used to prevent non-visible impact damage that significantly affects the load carrying capability of the part, etc.

Moreover, polymer applications determine a number of important column (hardware) design properties to get reproducible results and the most efficient separations. Most of them are related to the polymer conformation in the injection band moving through the column. 

Hardware designers have been building with standardized components for years. You don t design one new automobile rather, you design a family of them. Variations are made... 

When you re decribing how real world objects in a business organization (or a hardware design) interact with one another. This description is typically used to help explain the business in which a system is to be installed or updated. 

Most development teams could benefit from thinking more in terms of building their own components for their application area. This is the key to fast, reliable development to do it the way hardware designers have been doing it for two centuries and build components that can be assembled together in many combinations. Most end products—and indeed most components—should be assemblies of smaller components, built either elsewhere or in-house.

Argonne National Laboratory, (ANL) is pursuing fuel processor technology development that ranges from catalyst development, to component (CO, S cleanup, etc.) evaluations, to fuel processor hardware design, modeling, and demonstration. 

The sample valve must be made so that it can be activated automatically at the command of the switching code. Also, in terms of hardware design, CC demands a reliable sample switch which must switch many more times over a given analysis cycle than it would have to if run in the single pulse chromatography mode. Since the sampling valve is probably the most unreliable component... 

Considerable interest has been generated in turbulence promoters for both RO and UF. Equations 4 and 5 show considerable improvements in the mass-transfer coefficient when operating UF in turbulent flow. Of course the penalty in pressure drop incurred in a turbulent flow system is much higher than in laminar flow. Another way to increase the mass-transfer is by introducing turbulence promoters in laminar flow. This procedure is practiced extensively in enhanced heat-exchanger design and is now exploited in membrane hardware design. 

In a previous paper (16) the hardware design of the SEC/Viscometer system used in this work has been described. The effects of operational variables, e.g. pump pulsations, flow rate and flow irregularities on the performance of the viscometer and the enhancement of the signal-to-noise ratio by using mechanical dampers also has been described. Our current work has focused on the development, implementation and application of automated data... 

The effect on detonation transfer of the parameters shown in Fig Ex22 were reviewed for the donor and acceptor expls RDX, HNS-1 (2,4,6,2/,4/,6/-Hexanitrostilbene of 3 microns particle size) HNS-11 (Same as HNS-1, except of 200-300 microns particle size), DATB (1,3-Diamino-2,4,6-trinitrobenzene), and TATB (1,3,5-Triamino-2,4,6-trinitrobenzene) with a wide cross-section of sensitivities. Eash of these parameters has been individually qualified and explained on both the theoretical level and the impact on practical hardware design. The experimental study is described in Ref 2 Refs 1) M.L.Schimmel, "Quantitative Understanding of Explosive Stimulus Transfer... 

KINPTR is an overall process model thus it simulates all important aspects of the process which affect performance. In order to lay a foundation for upcoming discussions related to KINPTR development, the important aspects of naphtha reforming—chemistry, catalysis, and reactor/hardware design—will be summarized. More extensive reviews are available in the literature (1-3).
