Abstract: A pulp-molded paper lid for a beverage cup and a method for fabricating the same is introduced. While said pulp-molded paper lid bears an external pressure to accommodate the convex-ridge ring of the cup body therein, by preloading of an insertion force of said convex-ridge ring, a generating-elasticity device of said pulp-molded paper lid is pre-compressed to compressively deform, along inward directions respectively opposite to radial directions of said pulp-molded paper lid. By removal of said external pressure, a movable bearing wall and an outermost sidewall of said generating-elasticity device exert two reversed elastically-rebound forces by a stretched deformation occurring therebetween, for clamp-retaining two opposed sides of said convex-ridge ring. Said generating-elasticity device is released from the pre-compression to exert preloaded elastic forces along said radial directions, for strengthening the clamp-retention and avoiding the technical problems of the prior arts.

Abstract: A social networking system generates a newsfeed for a user to view when accessing the social networking system. Candidate stories associated with users of the social networking system are selected and an expected value score for each candidate story is determined. An expected value score is based on the probability of a user performing various types of interactions with a candidate story and a numerical value for each type of interaction. The numerical value for a type of interaction represents a value to the social networking system of the type of interaction. Based on the expected value scores, the candidate stories are ranked and the ranking used to select candidate stories for the newsfeed.

Abstract: A bottom for a paper cup is formed by advancing a punch against a paperboard web to push the web against a cutting edge which cuts out a circular cup bottom blank from the web. The punch is kept in a forward state to clamp an outer peripheral portion of the blank immovably against a surface of a sleeve. A reciprocable draw is advanced against a center portion of the blank to push the center portion into a circular opening of the sleeve while maintaining the clamping force, to cause the center portion of the blank to become stretched. The clamping force is then progressively released to permit the outer peripheral portion to enter the opening and become bent to form a lip extending at a substantially right angle. The lip is compressed within a gap formed between the draw and a surface of the opening. Because of the stretching of the blank, pleats formed in the lip are only in the form of micropleats that are flattened in a non-folded over state.
