International Classification:

B65G 1530

US Classification:

1988442, 24 38

Abstract:

A flexible cover for protecting a splice of a conveyor belt, in particular, for protecting the belt fastener that forms the splice. The splice cover includes a body having a first surface and an opposite second surface, with a plurality of first reclosable fasteners extending from the first surface. The first reclosable fasteners engage with a plurality of second reclosable fasteners, which are attached to the belt. The second reclosable fasteners can be secured to the belt by the belt fastener, by adhesive or other attachment means, by being integral with the belt fastener, or by being integral with the belt web. The second reclosable fastener can be any structure that engages, interlocks, mates, or otherwise attaches to first reclosable fastener. Also provided are methods for making the splice cover, and methods for placing and removing the splice cover over the belt fastener.

US Classification:

428195, 428205, 428207, 428211, 428212, 428213, 428500

Abstract:

A receptor medium with a sheet having an optically transmissive microembossed imaging surface as one major surface thereof. The receptor medium can receive jettable materials, which include inks, adhesives, biological fluids, chemical assay reagents, particulate dispersions, waxes, and combinations thereof. The microembossed medium unexpectedly solves such common inkjet printing problems as feathering, banding, and mudcracking in inkjet printing systems by controlling how an inkjet drop contacts and dries on an inkjet receptor medium and also Moire effects but also provides sufficient optical transmissivity to be useful as overhead transparency media, backlit signage, and the like. Clear lines of demarcation between adjoining colors of a pigmented inkjet image graphic can be obtained without creation of the Moire effects. Methods of making and using the inkjet receptor medium are also disclosed.

Abstract:

A receptor medium with a sheet having a random microembossed imaging surface as one major surface thereof. The receptor medium can receive jettable materials, which include inks, adhesives, biological fluids, chemical assay reagents, particulate dispersions, waxes, electrically, thermally, or magnetically modifiable materials, and combinations thereof. The random microembossed medium unexpectedly solves such common inkjet printing problems as feathering, banding, and mudcracking in inkjet printing systems by controlling how an inkjet drop contacts and dries on an inkjet receptor medium and also Moire effects. Clear lines of demarcation between adjoining colors of a pigmented inkjet image graphic can be obtained without creation of the Moire effects. Methods of making and using the inkjet receptor medium are also disclosed.
