Abstract: A method and system for an electrically conductive self-lubricating bearing includes a mating structure having a mating surface; an electrically conductive substrate, wherein the substrate includes a substrate surface having a plurality of valleys defined by at least one electrically conductive rib extending therefrom; and a lubricating material, wherein the lubricating material is disposed within the plurality of valleys, an exposed surface of the lubricating material substantially flush with an end defining a length of the rib so as to be communicated with the substrate surface and the mating surface, wherein the rib is in electrical communication with the mating surface.

Abstract: A hybrid bearing system that has a self-lubricating portion and a grease lubricated portion each being disposed on the same surface, the system is adapted to accommodate at least two distinct wearing forces generated by different types of motions. The bearing system includes: a first member; a second member, the second member being configured to be rotatably received within the first member; a self lubricating machineable liner system disposed between the first member and the second member; a receiving area disposed on the self lubricating liner system and a portion of either the first or the second member; and a lubrication opening in fluid communication with the receiving area, the lubrication opening providing structure for disbursing a lubrication grease within the receiving area.

Abstract: A thin self-lubricating film bearing system including a mating structure having a mating surface, a substrate, wherein the substrate includes a substrate surface having a plurality of valleys, wherein the substrate is disposed so as to communicate the mating surface with the substrate surface and a lubricating material, wherein the lubricating material is disposed relative to the substrate so as to be communicated with the substrate surface and the mating surface.

Abstract: Flowable molten plastic material is fed downwardly into an adjustable converging hopper mounted on a horizontal extruder barrel. This hopper is positioned around an opening feeding down into the barrel for guiding and deflecting a descending "rope" of plastic material into engagement with screw flights of a rotating feed screw extending along the axis of the extruder barrel. The hopper comprises a box-like structure open at top and bottom and having two opposed side walls which slope inwardly downwardly toward each other for providing a downwardly converging configuration with a pair of vertical parallel end walls interconnecting the side walls. A larger of the two sloping side walls extends downwardly farther than the other and is inclined to vertical at a large angle than the shorter side wall.
