Abstract: A pipe wrench is provided, including a first lever member, a pivot and a second lever member. The first lever member includes a first grip portion, a first clamping portion and a body portion, and the body portion has at least one guide toothed groove. The pivot is slidably disposed within the at least one guide toothed groove, and the pivot is slidable along an axial direction to be on a locked position or a released position. The second lever member include a second grip portion, a pivot hole and a second clamping portion, and the pivot is disposed through and pivoted to the pivot hole.

Abstract: The present disclosure relates to methods and systems for querying data in a data repository. According to a first aspect, this disclosure describes a method of querying a database, comprising: receiving, at a computing device, a plurality of keywords; determining, by the computer device, a plurality of datasets relating to the keywords; identifying, by the computer device, metadata for the plurality of datasets indicating a relationship between the datasets by examining an ontology associated with the datasets; providing, by the computer device, one or more suggested database queries in natural language form, the one or more suggested database queries constructed based on the plurality of keywords and the metadata; receiving, by the computing device, a selection of the one or more suggested database queries; and constructing, by the computer device, an object view for the plurality of datasets based on the selected query and the metadata.

Abstract: The disclosure includes a welding cup system comprising a tube having an open top, an open bottom, a sidewall extending between the open top and the open bottom, and an open channel. The open channel may extend through an interior portion of the tube from the open top to the open bottom. The open top may be arranged and configured to slideably couple to at least a portion of a torch assembly. The open channel may be arranged and configured to allow gas to flow from the open top to the open bottom, and allow a welding electrode to extend through the open channel from open top towards the open bottom. The welding cup system may have a side profile that may define an asymmetrical shape.

Abstract: The pipe pliers includes a first clamping body, a driving handle, and a clamping element. The first clamping body includes a body portion. The body portion includes two side plates and is formed with two guiding toothed grooves. A receiving groove is defined between the two side plates. Each side plate is formed with a sliding groove facing the other side plate. The driving handle is slidably arranged at the two guiding toothed grooves and is pivotable with respect to the first clamping body. The driving handle has a protrusion. The clamping element is slidably arranged at the two sliding grooves. The clamping element has a recess. The protrusion is rotatably inserted into the recess. When clamping a workpiece, the clamping element slides linearly.

Abstract: The disclosure includes a lens jacket configured to cover an eyeglass frame comprising a first lens and a second lens connected. Embodiments of the lens jacket can include a soft material that extends along a first direction and a second direction. The soft material can comprise an inner surface and an outer surface. Embodiments of the lens jacket can also include a pivot axis that extends through the soft material and extends parallel to the first direction, a first attachment mechanism located along the first portion of the soft material, and a second attachment mechanism located along the second portion of the soft material. The first attachment mechanism can couple with the second attachment mechanism to thereby retain the soft material in a closed position to thereby protect the first and second lenses.

Abstract: A pack for carrying personal effects and protecting such effects from damage caused by contact with moisture is provided. First, a flexible and rugged water-resistant outer container having a resealable opening defines a cavity sized to receive a waterproof pouch along with various other items. Next, the waterproof pouch may have an opening to receive various items. A first means and a second means for sealing the waterproof pouch are successively spaced away from the opening of the pouch. Then, once sealed, a portion of the pouch may be successively folded over the first and second means for sealing the pouch to further reduce any risk that moisture enters the pouch through the sealed opening. Finally, means may be provided for securing the folded portion of the pouch in place to provide nested and redundantly sealed compartments.

Abstract: A case for enclosing a personal electronic device is disclosed that has at least one button molded into the case, wherein the button is manufactured from rigid material that may or may not deform when depressed. The case, whether hard or soft, may incorporate the buttons manufactured from a hard material and afford the user the same tactile response as if the user were depressing the underlying buttons on the device. The case may be co-molded with two similar or dissimilar materials. One of the co-molded materials may provide a membrane that allows the button to flex and also secures the buttons to prevent them from being dislodged from or out of the case.
