Cartridges, Cartridge Holders, and Their Care

The straight-through design has shortcomings, however. The layout of horizontal, rigid piping is often difficult to adapt to the incorporation of straight-through filter housings, since each opposing inlet and outlet connection must be gasket-sealed by compression to the housing. If the piping system cannot be separated for gasket and clamp installation or for placement using the housing threads, the unit cannot be installed. If the piping system is slightly movable, enough so that it can be separated, the pipe/housing interface must still be made perfectly in-line: The housing must seat flush to prevent leaking. Most often in those few instances where straight-through housings are used in rigid piping systems, flexible braided hose adapters are used for inlet and outlet hookups. Alternatively, straight-through housings are used at terminal sites within a rigid piping system.
Cable Shielding, Coupling from E and H Fields, and Cable Emissions
Published in David A. Weston, Electromagnetic Compatibility, 2017
Should an unshielded or a shielded cable be the culprit in a susceptibility/immunity problem or result in excessive radiation, the addition of an overbraid may solve the problem. Tin-plated copper braid is sold as shielding and bonding cables with IDs of 3.18 mm to over 25.4 mm. These braids can be either attached to a circular connector by use of a hose clamp, soldered to a brass connector, or clamped under a strain relief on a none EMI backshell, as described in the section on connectors. The measured transfer impedance of 1-m length of single tubular braid, double tubular braid, or triple tubular braid is shown in Figure 7.20.
Natural Fiber Reinforcement Design

The technique of braiding is very old and has been used by the ancient civilizations back to 4000 BC in manufacturing of hair forming, ropes and fabrics. The basic idea of braided structures is when three or more yarns intertwined in such way that no two yarns are twisted around another. Braiding processes have the ability to fabricate a wide range of complex shapes. Braiding process can form shapes either by over-braiding mandrels on conventional machine (two-dimensional process) or by using new braiding processes to form solid shapes (three-dimensional process). 3-D braided fabrics have found the applications in the areas including medicine, aerospace, automobiles, train components, and reinforced hoses [23]. The initial development of 3-D braided fabrics came from the composite and medical industries. 3-D braided fabrics can be manufactured in myriad varieties of cross-sections, and their near-net complex shapes made it possible to design very specialized products for both industries.
Low-cost leaky feeder communication for mines rescue

Another type of low-cost ‘low loss’ cable has a copper clad aluminium braid shield but no aluminium foil. Commonly, the percentage coverage of the braid is very low, with the obvious potential for leakage. A coverage of 40% is typical.
