An article having a bearing surface with improved wear characteristics is provided. The article may be formed from a composition that includes a polymeric material, a lubricious and reinforcing additive, and a solid lubricant. Methods for forming the compositions and structures are also provided.
摘要:
The invention relates to a method for joining two components (10, 12) made of a metal material, which are connected on two mutually associated joining surfaces (14, 16) by means of a joined connection, wherein at least one of the components (10) is strengthened in at least a partial region of the joining surface (14) thereof prior to joining. The invention further relates to a joined connection of two components (10, 12) made of a metal material.

A panel mounting structure for a vehicle is provided having a substrate; a panel; and a separable sound reduction member disposed between the panel and the substrate and being configured to separate into at least two pieces that each remain in substantially fixed relation to a different one of the panel and the substrate, and having a material selected so that the impact of the pieces with each other causes relatively little sound. The material can be configured to separate to form the at least two pieces due to relative motion between the substrate and panel. In specific embodiments, the sound reduction member can be comprised of a sound reduction member, such as felt, or a sound reduction member layer and an adherent backing layer.
摘要:
Drying section of a machine for producing a material web. The drying section includes a support roll with an associated impingement dryer, and at least one straight or curved section forming at least a part of a closed path between a last nip of a press section adjacent the drying section and the support roll. The support roll and the impingement dryer are arranged to guide the material web over the support roll, and, thereby, to subject the material web to at least one of hot air and hot steam impingement. The at least one straight or slightly curved section is structured and arranged to form at least one of an impingement drying section and a transfer foil section.
摘要:
A machine for producing a sheet, e.g., paper or cardboard, in which the machine may include a plurality of rolls having a bearing pin located at each end and a bearing device retaining each bearing pin. The bearing device may be utilized to guide the bearing pin on all sides, enabling a base of the bearing device to be arbitrary positioned at an angle 0.degree.

Locomotives comprising a chassis configured for receiving various modules such as, for example, fuel storage modules and/or power modules. By employing a selected combination of fuel storage modules and power modules, a locomotive may be constructed to employ any of one or more types of fuel, such as liquid fuels and gaseous fuels. Batteries may be employed to maximize energy use. Multiple locomotives may function together as a ‘consist’ having differing types of engines and using different types of fuel. A control system may be employed to optimize use of the engines by prioritizing factors such as cost, fuel efficiency, noise reduction, emissions reduction, etc.

摘要:
A fixed transparent module (FTM) for the roof of a vehicle having glass for cementing to the roof support surfaces to form a continuous seal; at least one compensation part running essentially parallel the roof support surface in a manner defining a space of substantially constant dimension between said outside surface of the compensation material and said roof support surface for receiving a cement layer of constant thickness; and at least one trim ring attached to said glass pane having a guide pin and attachment points, wherein said glass pane has added support, attachment points for additional features, and allowance for proper alignment of FTM to a vehicle body. Calibration stops can be added having a height that corresponds to the desired cement thickness of the cement layer. A reinforcement assembly, electric or manual sun shades can be added or, alternatively, the glass can be self darkening or use photoelectrochromic technology.
