Abstract: An indestructible handle for a mop or broom or the like comprises a tubular steel handle member with a solid steel plug mounted in the end thereof and protruding out of the end. The exterior of the steel plug is provided with a modified Acme thread that fits a standard thread on a push broom. The outer end of the steel plug includes a threaded opening such that it can fit on a threaded handle attachment stud on a mop frame. A plastic sleeve encases the handle member. The steel plug is mounted in the end of the handle member by crimping the handle member over the portion of the plug extending into the handle member at three equally spaced points around the handle. The threads on the plug extend into the handle, and crimping tools having a plurality of pointed projections thereon at each of the three crimping positions crimp the tubular member so that the tube is crimped inwardly between the threads of the plug, thus holding the plug in the end of the tubular member.

Abstract: A method for preparing a siloxane foam by mixing an organohydrogensiloxane, a hydroxylated organosiloxane, a platinum catalyst, and an aluminum silicate, and thereafter allowing a foam to form. Preferably, the aluminum silicate comprises about from thirty percent (30%) to about forty percent (40%) by weight of the total composition. The new foams are economical and have improved fire retardancy, physical strength, sealing and wear characteristics, and consistency of composition. The new foams are especially useful as fire retardant insulation in the construction industry, especially as a protective encasement for mechanical and electrical wires, pipes, conduits, and the like.

Abstract: A throttle control device for use with a spring-return throttle wherein a rotatable sleeve on a handlebar must be rotated to advance the throttle, the throttle control device including a clamping arrangement receivable over the rotatable sleeve to be just forward of a handgrip normally received over the sleeve, the clamping arrangement having a tab that engages conventional equipment to prevent rotation of the clamping means, and including a lever operated cam for clamping the sleeve to hold the throttle in a pre-set position, the clamping arrangement being held in position by the handgrip.
