Snap In Weatherstripping

Номер: US20120009378A1

Автор: James Allan Micket, Steven Robert Abramson

Принадлежит: GREENSTAR TECHNOLOGIES LLC

A snap in weatherstripping where the backing has a plurality of alternating notched out spaces along each side to facilitate ease of insertion into a channel without the need to slide the weatherstripping longitudinally into the channel. The snap in weatherstripping can be pushed into the channel with a gentle side to side or rolling motion, thus eliminating the difficulties associated with longitudinally sliding a weatherstripping into a channel. The snap in arrangement of the weatherstripping eases replacement, and also accommodates variations in tolerance between the weatherstripping and the channel, making it desirable for replacement of existing degraded weatherstripping.

Phosphorus 0.015 max. Sulfur 0.010 max. Chromium 19.00-21.00 Nickel 33.00-37.00 Molybdenum 9.00-10.50 Titanium 1.00 max. Boron 0.010 max. Iron 1.00 max. The balance is cobalt and usual impurities. The wire is annealed at a combination of temperature and time effective to provide a grain size of about ASTM 6 or finer and is then drawn to provide a reduction in cross-sectional area of about 50 to 80%. The wire is—then heat treated under temperature and time conditions effective to provide the wire with high strength and sufficient wrap ductility that the wire does not crack or break in a standardized wrap test.

Components with improved erosion resistance are disclosed. A surface of the component or a substrate of the component is modified by coating the substrate with an elastomer layer. The elastomer layer is then modified by embedding hard particles onto an outer side of the elastomer layer.

A method of producing a multilayer magnetoelectronic device and a related device. The method includes depositing a multilayer structure including at least two ferromagnetic layers disposed one on top of the other and each having a magnetic anisotropy with a corresponding magnetic moment. A magnetization curve is specified for the magnetoelectronic device. The number of ferromagnetic layers and, for each of the ferromagnetic layers, the magnetic moment and the magnetic hardness for obtaining the specified magnetization curve are determined. For each of the ferromagnetic layers a magnetic material, a thickness, an azimuthal angle and an angle of incidence are determined for obtaining the determined magnetic moment and magnetic hardness of the respective ferromagnetic layer. The multilayer structure is deposited using the determined material, thickness, azimuthal angle and angle of incidence for each of the ferromagnetic layers.

More particularly, it relates to a fluid composition, and microencapsulation of the fluid composition, that inhibits corrosion and tarnishing and that may be relatively non-toxic. The VCI is intended to be employed in varying concentrations depending on the intended application and deployed via microcapsules. The microcapsules may be adapted to release the VCI over time, or all at once. To effect this, the microcapsules may be adapted to be breached at varying times or at the same time. By adapting the microcapsules, or the method of breaching the microcapsules, the rate at which the VCI is released may be controlled.
