Abstract: An expansion joint seal for use preferably in walkways and the like having a pair of elongated, parallel spaced-apart slab members defining a gap therebetween with each of the slab members having a generally C-shaped cavity opening toward said gap. The seal includes mounting beads on each of its longitudinal edges for assembly within the aforesaid slab cavities and an intermediate section spanning the aforesaid gap and being attached to the mounting beads. Each mounting bead is of tubular construction and includes an outer wall surface configuration generally adapted for matching engagement with said cavity. The radius of curvature of each mounting bead outer wall portion in an unstressed, disassembled condition is less than the radius of curvature of the corresponding cavity so that upon assembly of the mounting bead within the cavity the outer wall portion is forced to assume the curvature of the cavity resulting in a highly effective mounting of the bead.

Abstract: A method and apparatus for separating particulate matter from a gas stream wherein dirty gas is moved through an electrostatic charging zone such as an electrostatic precipitator and then is moved through a filter of foraminous material such as a fabric filter of the bag type.

Abstract: The invention relates to the recovering of free metal entrained in dross or skimmings obtained from melts of aluminum and aluminum based alloys wherein the dross has been partially prepared by prior art preparation processes. The invention is directed to the cleaning and preparation of the dross by the more effective removal of substantial portions of the oxide coatings on the dross. This results in the recovery of a significantly higher proportion of the free metal contained in the dross than is recovered using prior art cleaning and recovery processes. The dross, as partially processed by prior art methods, is sequentially fed through selected mechanical rolling and milling stages so as to separate aluminum oxide dust and aluminum concentrates from one another. The aluminum concentrates may be utilized in conventional furnace recovery methods to produce aluminum ingot or may be further processed through selected stages to produce high quality aluminum pellets.
