A stacked dispenser-napkin composition having a plurality of stacked and interfolded dispenser napkins; each dispenser napkin being embossed and having a male side of the emboss and a female side of the emboss; each dispenser napkin having a first, second, third, and fourth panel, the four panels being defined by a first fold and a second fold; each dispenser napkin's first and second panels being adjacent to each other and having respective areas that are substantially equal; each dispenser napkin's third and fourth panels being adjacent to each other and having respective areas that are substantially equal; the combined areas of each dispenser napkin's first and second panels being greater than the combined areas of the dispenser napkin's third and fourth panels; each dispenser napkin having a tab portion, the tab portion being the portions of the first and second panel areas that are not covered by the third and fourth panel areas when the first and second panels are folded onto the third and fourth panels via the first fold; the plurality of stacked and interfolded dispenser napkins being arranged within the stack such that the positions of the respective tab portions on adjacent dispenser napkins alternate between two opposing sides of the stack; and the plurality of stacked and interfolded dispenser napkins being arranged within the stack such that the position of a stacked dispenser napkin's male side of its emboss is in contact with an adjacent dispenser napkin's female side of its emboss.

Tabbed easy sliding interfolded dispenser napkins

A vulcanizate comprising a rubber, and a damping component that is prepared by preparing a mixture of living polymers that include living polymers with at least two living ends and living polymers with one living end to form a mixture of living polymers, and coupling the mixture of living polymers with a coupling agent that has at least three reactive functionalities.

Rubber compositions and vulcanizates including comb-branched polymers

A composition comprising an elastomer, a filler, and a comb-like polymer, the comb-like polymer comprising a backbone and a plurality of side chains, the backbone having a length greater than or equal to the entanglement length, the side chains having a length greater than about 33% of the entanglement length, the backbone including at least one side chain per entanglement length, and the comb-like polymer having a T of less than &minus;5&deg; C.

A vibration damping device is mounted between two spaced portions of a vehicle for absorbing road forces exerted on the vehicle. A cylindrical housing forms an internal piston chamber and is connected at one end to one portion of the vehicle, with an outer end of the rod of a piston which is slidably mounted within the piston chamber, being connected to another portion of the vehicle. A fluid transfer duct is formed between the housing and piston and provides communication between fluid subchambers formed on opposite sides of the piston within the piston chamber. An electrode is attached to either the housing or piston for applying a voltage across the duct to affect the rheological response of an electrorheological (ER) fluid flowing therethrough to provide a controllable mechanism to modify the damping force characteristics of the device. Each end of the piston rod is slidably supported by a slide bushing assembly which is mounted within an end of the housing. The slide bushing assemblies are separated from the ER fluid contained in the fluid chamber by elastomeric seals to reduce bushing wear and deterioration of the ER fluid.

A process for polymerizing 1,3-butadiene into a low molecular weight high-cis polybutadiene is described using a catalyst system comprising: (a) a neodymium-containing compound, (b) an aluminoxane or a trialkyl aluminum compound, (c) an organoaluminum hydride, and (d) a halogen source. A blend of a high molecular weight high-cis polybutadiene and the low molecular weight high-cis polybutadiene is also disclosed for use in pneumatic tire treads. Desirably both the high and the low molecular weight polymers have high cis contents, with the low molecular weight polymer being at least 70 percent cis and the high molecular weight polymer being at least 92 percent cis. Desirably both polymers are made with a neodymium catalyst system. The blends provide a balance of properties including good snow traction, wet traction, and rolling resistance while providing a balance of good physical properties including tension at break, modulus etc.

Low molecular weight high-cis polybutadienes and their use in high molecular weight-low molecular weight high-cis polybutadiene blends

A method for increasing the damping properties of tire rubber comprising the steps of adding an unsaturated damping additive to a vulcanizable composition of matter, and processing the vulcanizable composition of matter containing the damping additive into tire rubber.

Elastomeric compositions for damping

A vibration damping system for absorbing shock loads includes a hydraulic damper containing a piston slidably reciprocating within an oil filled chamber and dividing the chamber into a pair of subchambers. A hydraulic motor is in fluid communication with and located between the subchambers and is controlled by a field responsive fluid, such as an electrorheological (ER) actuated device. The hydraulic motor transforms fluid motion into rotating motion by a pair of meshing gears. The ER device is a flow cell and is connected to a shaft of one or both of the meshing gears. The magnitude of an electric field applied to the ER fluid controls the flow rate of the hydraulic fluid passing through the hydraulic motor by controlling the resistive force to the rotary motion of the gears. A plurality of check valves controls the direction of flow of the hydraulic fluid between the hydraulic motor and the subchambers.
