International Classification:

B01D 5000

US Classification:

55495, 55490, 55497, 55498, 55507, 55510, 55DIG 5

Abstract:

An air filter element has a cylindrical filter media sleeve axially slidable along and around an inner liner from either axial end of the sleeve. First and second end caps at distally opposite axial ends of the liner and sleeve each have a central aperture, the aperture in the first end cap providing air flow therethrough in communication with the hollow interior of the liner, the aperture in the second end cap retaining a closing cover. The cylindrical filter media sleeve extends axially along the inner liner and is axially retained between the cover and the first end cap. The cover is removably mounted to the second end cap in snap-in relation and axially retains the sleeve on the inner liner.

US Classification:

177136

Abstract:

A problem that is often encountered under uneven terrain conditions with on-board load weighing systems for vehicles, such as logging trucks, having a frame member and a load support member to which a load which is to be measured is applied, is that structural failures occur in the load cell assemblies included in the on-board load weighing system. The cause of these structural failures is traced to rotation of the load cell assemblies resulting in undue tensive forces in the load cells thereof. Various restraining devices are discussed for limiting the upward deflection of an upper, load concentrating portion of the load cell to maintain the tensive forces within acceptable levels.

US Classification:

177134

Abstract:

An improved load scale of the type wherein a platform supporting a vehicle and a load to be weighed has a plurality of load cells disposed under and across each end of the pair of opposed ends and between the platform and a supporting surface. The improvement comprises a plurality of Z-shaped lateral support beams with each beam having an upper flange and a lower flange thereon. The plurality of Z-shaped lateral support beams extend across each end of the pair of opposed ends of the platform between the platform and the plurality of load cells such that the lower flange of the support beam carries the platform and is secured thereto, and the upper flange of the support beam spans the gap between adjacent load cells and rests across the tops thereon. A further improvement comprises a weight distribution means with a first base plate disposed upon the support surface with a plurality of second base plates being disposed above said first base plate and being separated therefrom by a sheet of material having a non-linear compression characteristic.
