20130333109 | Fixing Structure of Faucet - A fixing structure of a faucet is mounted on a sink countertop with an opening and contains a base including a supporting portion and an inserting portion. A supporting portion has an annular fence and an annular shoulder; the annular fence has a retaining recess; the annular shoulder has two longitudinally through holes and an opening. The inserting portion has a cylindrical fence and two stopping rods, and the cylindrical fence has a longitudinal channel; the annular shoulder has an annular abutting area. A locking assembly includes two positioning screws and two clamping blocks. A faucet includes a fitting tube, a sheath having a groove, a peripheral fence, and a threaded orifice. A controlling valve assembly is mounted on the fitting tube. A fastening bolt is screwed with the threaded orifice so as to retain with the retaining recess, thus fixing the faucet on the base. | 12-19-2013 |
20140075667 | Fixing Structure of Faucet - A fixing structure of a faucet is fixed on a sink countertop with a hole and contains a faucet having a housing, a pull-out spray head, a mixing valve, and a water supply set. The water supply set includes a cold-water inlet pipe, a hot-water inlet pipe, and a mixing outlet pipe. A positioning device includes a base having a peripheral fence, a bottom fence, and a mouth. The bottom fence has a limiting face and at least one orifice, the limiting face has a channel, two stop posts, and an abutting face. Two screw rods extend out of the hole and are rotated above the base. Two clamping blocks are screwed with the two screw rods and are limited by the two stop posts to rotate when the two screw rods are rotated, and the two clamping blocks move upwardly to retain a bottom end of the sink countertop. | 03-20-2014 |

20140040152 | METHODS AND SYSTEMS FOR FAKE ACCOUNT DETECTION BY CLUSTERING - Techniques to determine fake accounts of a social networking system. In one embodiment, a magnitude of a cluster of accounts is calculated. The social networking system determines the accounts are fake when the magnitude of the cluster is less than a threshold value. The accounts are not determined to be fake, or determined to be not fake, when the magnitude of the cluster is equal to or greater than the threshold value. The accounts may be associated with at least one resource. A mapping of the accounts may be created based on features associated with the accounts. A radius of the cluster is compared with the threshold value. The accounts are determined to be fake when the radius is less than the threshold value. | 02-06-2014 |
20140259156 | DETECTION OF LOCKSTEP BEHAVIOR - Disclosed here are methods, systems, paradigms and structures for determining fraudulent content in a social network. The methods include identifying a plurality of users of the social network who perform a plurality of tasks within the social network in a lockstep manner. In the method, the plurality of users are determined to be performing a given task in the lockstep manner when the plurality of users each perform the given task within a predefined duration of time, where the predefined duration of time is associated with the given task. The method further includes identifying content data generated by the performance of the plurality of tasks by each of the plurality of users. The method further includes determining at least a portion of the content data generated by the performance of the plurality of tasks as fraudulent content. | 09-11-2014 |
