US Patent:

39424308, Mar 9, 1976

Filed:

Jun 10, 1974

Appl. No.:

5/477787

Inventors:

David Roger Day - Madison Heights MI
Lucian Grant McElroy - Lapeer MI

International Classification:

B30B 1522

US Classification:

100 52

Abstract:

A compactor assembly for compacting matter including a housing, a compactor plate within the housing movable between a retracted position and a compacting region for compacting matter wherein the compactor plate is inclined with respect to the path of motion in the retracted position and moves toward the perpendicular with respect thereto in the compacting region, the compactor plate including collapsible means for permitting collapse thereof as it approaches the perpendicular. In one preferred embodiment, the compactor plate includes stapling means for stapling adjacent layers of matter together during the compaction process wherein the stapling means includes a plurality of movable teeth.

International Classification:

C08F 822

US Classification:

427 38

Abstract:

Conductive materials are formed by implanting high energy ions (30 keV to 300 keV) into rigid backboned polymers, such as poly (p-phenylene sulfide); conductivities on the order of 10. sup. -3 (ohm-cm). sup. -1 are demonstrated and the materials remain stable over periods as long as a year.

Appl. No.:

6/338577

Inventors:

Lucian G. McElroy - Metamora MI
David R. Day - Corpus Christi TX

International Classification:

B08B 100
B08B 1300

US Classification:

134 6

Abstract:

An adjustable clamp (26) for selectively varying the hinging action of a flexible, inflatable fluid-stripping bag (12) including an elongated bag inlet (14) having a predetermined cross-sectional area and a nozzle (16) at one end thereof and wherein the bag inlet (14) is mounted about an opening (24) of a plenum (20) for supplying air to the bag (12). The clamp comprises an adjustable frame (26) adapted to be disposed about the bag inlet (14) and spaced therefrom to adjustably limit the extent to which the bag inlet (14) opens to determine the cross-sectional area and a band member and fastening device for securing the frame (26) about the bag inlet (14) whereby a change in the cross-sectional area produced by the frame (26) changes the resistance of the hinging action of the bag (12). A method is also provided for selectively varying the hinging action of the flexible, inflatable fluid-stripping bag (12) including the steps of mounting the bag inlet (14) about an opening (24) of a plenum (20) for supplying air to the bag (12) and characterized by selectively varying the cross-sectional area of the bag inlet (14) to vary the hinging action of the bag (12) whereby changing the cross-sectional area of the bag inlet (14) changes the resistance to hinging action of the bag (12).

International Classification:

F26B 1900

US Classification:

15316R

Abstract:

An apparatus 10 for stripping fluid from the surface of a vehicle including a plenum 14 and a flexible inflatable primary bag 20 having a primary bag inlet releasably mounted on the plenum 14 for allowing the flow of air from the plenum 14 to the primary bag 20 and a nozzle end 22 and a bag opening 24 disposed between the primary bag inlet and the nozzle end 22. The apparatus further includes a flexible inflatable secondary bag 26 having an elongated secondary bag inlet 28 secured about the bag opening 24 for hinging movement and a nozzle end 30 for allowing the flow of air therethrough. The apparatus is characterized by including a hinging control frame 34 for controlling the hinging action of the secondary bag 26 with respect to the primary bag 20.
