摘要： A roller assembly for use, for example, in agricultural machines where the roller assembly has an exterior surface portion adapted to contact a conveyor element supporting the agricultural products and a bearing sub-assembly positioned about an axle in the center of the roller assembly. The bearing sub-assembly has at least one bearing, at least one sealing element having an elastomeric sealing portion positioned outboard of the bearing and at least one standoff also positioned outboard of the bearing. There may be a plug in place of one of the sealing elements, the plug being elastomeric and configured to make a compression fit with the hub.

摘要： A roller assembly for use, for example, in agricultural machines where the roller assembly has an exterior surface portion adapted to contact a conveyor element supporting the agricultural products and a bearing sub-assembly positioned about an axle in the center of the roller assembly. The bearing sub-assembly has at least one bearing, at least one sealing element having an elastomeric sealing portion positioned outboard of the bearing and at least one standoff also positioned outboard of the bearing. The standoffs have grooves in their outer dimension adapted to receive the elastomeric sealing portion. The diameter of the standoffs are about the same as the diameter of the elastomeric sealing portion. The horizontal length of the standoffs may also be chosen so as to offset the exterior surface portion of the assembly a predetermined distance with respect to the conveyor element.

摘要： A polymer polyol is produced by a process comprising free radical polymerizing an addition polymerizable di-(substituted phenyl)monomer (e.g., methacrylic ester of diglycidylether of tetrabromobisphenol A) component in the presence of a polyol, wherein the monomer has at least one aromatic halogen and at least one aromatic ethylenically unsaturated substituent. The polymer polyol can also be made by copolymerizing said monomer with an additional ethylenically unsaturated monomer component such as styrene and acrylonitrile. Said polymer polyols are reacted with a polyisocyanate compound forming a flame retardant polyurethane foam.

摘要： An insulated wall panel comprising of two outer layers, an insulating foam core, and a spacer within the foam core which holds the panel spacing and retains the foam during foam introduction and expansion in the cavity and remains as part of the panel. The panel has no thermal bridging between the outer layers and is manufactured with reduced need of rigid mold forms. The final effect after pouring becomes a monolithic foam core of substantially consistent material and provides a superior product to using dissimilar retained spacing materials.
