  • Patent number: 11833709
    Abstract: The staves for producing wooden barrels are assembled of individual segments which are fixedly connected to each other at end faces. The individual segments are shorter wood pieces that are assembled such that the stave has the required length. The wooden barrel is produced of such staves which are placed against each other seal-tightly with their narrow sides. The individual segments are machined at their end faces such that individual segments resting against each other after assembly are positioned at an angle relative to each other and form a raw stave that is curved across the length.

  • Patent number: 4484021
    Abstract: A resilient gasket for a weatherproof electrical outlet provides seals between the outlet box and the cover plate, between the receptacle and the cover plate, and between the cover plate and cover flap or plug connected to the receptacle. The gasket is a planar member having a peripheral configuration corresponding to the peripheral configurations of a standard outlet box and cover plate therefor and is received between the cover plate and receptacle and between the cover plate and outlet box. At least one aperture extends through the gasket and has transverse dimensions, in a relaxed condition of the gasket, less than the similar dimensions of projections on standard electrical receptacles.
