Abstract: A plastic crab trap that is molded in one operation, including a cover member, and side walls that are adequately reinforced for rigidity, taper upwardly and have slots through which water can flow. The cover is molded in place in what will be the top opening, but reversed from its operating portion, and is connected in the opening through sprues which feed plastic from the input opening for plastic material after molding the cover. After molding, the cover is cut loose from the main part of the crab trap, and upon rotating the cover 180.degree. provided hinge and latch members between the cover and the main body of the crab trap are properly positioned without further operations. Additionally, a specific bait box holder is provided adjacent to the cover so that when the cover is closed, the bait box will be held in place, and can be easily removed for service once the cover is opened.

Abstract: A thermal ribbon having a minute coating of graphite powder on the outer side of the resistive layer. The improved electrical interface with print electrodes reduces ribbon and printhead damage. The graphite also reduces friction and loosens material which builds-up at the printhead.
