    摘要: In accordance with one embodiment, a foot assembly for use with a walker may include an attachment assembly for engaging a leg tube of the walker. A coupling device, such as a screw, may be used to couple the attachment assembly with a slider foot. The coupling device permits rotational and angular movement between the attachment assembly and the slider foot. In some embodiments, the walker may include three or four legs which are connected by a structure which maintains the legs in a fixed spatial relationship. A separate foot assembly may be affixed to one or more of the legs of the walker.

    摘要: An improved crash attenuator that uses a cable and shock arresting cylinder arrangement to control the rate at which a vehicle impacting the crash attenuator is decelerated to a safe stop is disclosed. The crash attenuator is comprised of a front section and a plurality of mobile sections with overlapping angular corrugated side panels. When the crash attenuator is impacted by a vehicle, the front section and mobile sections telescope down in response, and thus, are effectively longitudinally collapsed. For this purpose, the sections are slidably mounted on at least one guiderail that is attached to the ground. Positioned preferably between two guiderails is the cable and cylinder arrangement that exerts a force on the front section to resist the backward movement of the front section when struck by an impacting vehicle using a varying restraining force to control the rate at which an impacting vehicle is decelerated to safely stop the vehicle. The side panels can also be used in a guardrail configuration. A variety of transition arrangements to provide a smooth continuation from the crash attenuator to a fixed obstacle protected by the crash attenuator.

    摘要: A paving mat for use in a paved surface includes a fibrous mat in the form of a paving mat. The fibrous mat includes a fibrous matrix containing a mixture of polymer fibers, first mineral fibers having a first median length, and second mineral fibers having a second median length that is different from the first median length. In another embodiment, the paving mat includes a fibrous mat including a fibrous matrix which is bonded together by a binder. In one embodiment, the binder is a mixture of different binders. The fibrous matrix includes a mixture of mineral fibers in an amount within a range of from 61 wt % to 85 wt % and polymer fibers in an amount within a range of from 15 wt % to 39 wt %. The polymer fibers have a melting point greater than 320° F. (160° C.). The mat has a stiffness in the machine direction within a range of from 65 g-cm to 110 g-cm. The mat has a load-elongation behavior such that when the mat is subject to tensile stress, the mat achieves at least 90% of its ultimate load at an elongation not greater than 5% of the specimen length in the direction of applied stress. Another embodiment of the paving mat is made with a carboxy-modified acrylic binder.
