Abstract: A fail-safe signal injection system includes a fail-safe system controller that receives a control command and initiates to bypass a first system to inject a control signal into a second system responsive to the control command. The fail-safe signal injection system also includes a signal injection circuit implemented to inject the control signal into the second system responsive to power applied to the signal injection circuit, the signal injection circuit further implemented to fail-safe without the power applied, and thus operates to pass a control input from the first system through to the second system. The signal injection circuit includes a fail-safe isolation circuit designed to pass the control input from the first system through to the second system when driven for fail-safe pass through, and bypass the first system to inject the control signal into the second system when driven to isolate the first system from the second system.

Abstract: This invention relates to blends of linear low density polyethylene copolymers with other linear low density polyethylenes or very low density, low density, medium density, high density, and differentiated polyethylenes. The invention also includes articles produced from the linear low density polyethylene and polyethylene blends described.

Abstract: The invention concerns films having a cling layer of an elastomeric propylene-based polymer with a low heat of fusion derived from isotactic propylene type crystallinity, as determined by DSC of less than 40 J/g, optionally blended with a crystalline isotactic propylene derived polymer having a heat of fusion over 70 J/g and/or a melting point of at least 120° C. as determined by DSC, and a non-cling layer of a polyolefin. The cling layer may contain other components such as crystalline polypropylene.

Abstract: Blends of very low density polyethylene produced using metallocene catalysts (mVLDPE) and linear low density polyethylene (LLDPE) are disclosed. The polymer blends include a metallocene-catalyzed VLDPE polymer having a density of less than 0.916 g/cm3, the VLDPE polymer preferably being linear and without long chain branching, and a LLDPE polymer having a density of from 0.916 to 0.940 g/cm3. The polymer blends are particularly suitable in blown and cast film applications.
