Abstract: A resilient gasket seals a connection between a wallplate rim and a wall, and is formed in situ by locating an insert on the backside of the wallplate inside of the rim and then introducing a flowable gasket material therebetween. The insert serves as a temporary dam during the in situ formation of the resilient gasket and is adapted to be removed from the wallplate prior to mounting to the wall. The insert extends above the wallplate rim, thereby protecting the resilient gasket during shipping, and also enabling vertical stacking of the wallplates prior to curing of the flowable gasket material. Use of this insert reduces the manufacturing time and labor costs in forming such wallplates.

Abstract: A lance extension venturi sleeve is disposed preferably within the rear one-third of the lance extension of a powder spray gun. The sleeve increases the velocity of the powder stream and provides an abrupt opening to the larger lance extension tube. The velocity increase and the turbulence so created increase the homogeneity of the powder in the stream and produce a more uniform powder spray pattern or powder "cloud" for even powder coating of articles to be coated.

Abstract translation: 喷枪延伸文丘里套管优选地设置在粉末喷枪的喷枪延伸部的后部三分之一内。 套管增加了粉末流的速度，并向较大的喷枪延伸管提供了突然的开口。 速度增加和如此产生的湍流增加了流中粉末的均匀性，并产生更均匀的粉末喷涂图案或粉末“云”，用于均匀涂覆待涂层的物品。

Abstract: A method and apparatus for applying hot melt adhesive to the parting surfaces of sections of a foam pattern employed in the lost foam metal casting process includes an adhesive applicator operable to dispense a layer of adhesive in a desired pattern onto a transfer surface. The parting surface of a section of a foam pattern is then brought into engagement with the transfer surface so that at least a portion of the adhesive adheres to the parting surface for assembly with a mating section of the foam pattern. The adhesive remaining on the transfer surface after engagement with the parting surface is scraped off and a new layer of adhesive applied in preparation for another section of the foam pattern.
