Abstract: Techniques are provided for proposing automatic corrections of online identifiers, such as an email address or a subject name of a directory entry or a certificate. In an embodiment, one or more computers store domain correction records. Each domain correction record comprises a misspelled domain name and candidate domain name corrections. The computers detect that an unprocessed online identifier is not contained in a plurality of known online identifiers. The unprocessed online identifier comprises a misspelled domain name. Each known online identifier of the plurality of known online identifiers comprises a domain name. The computers retrieve, based on the misspelled domain name of the unprocessed online identifier, from the plurality of domain correction records, a matching domain correction record having a same misspelled domain name as the unprocessed online identifiers. A client device displays the one or more candidate domain name corrections of the matching domain correction record.

Abstract: Embodiments disclosed herein relate to an extruder for a 3D printer. The extruder for a 3D printer includes a finned head, a lower tube being accommodated at the lower portion of the finned head, a heating base accommodating a lower portion of the lower tube, and a dispensing nozzle being fitted at a coinciding hole at the heating base. The lower tube is characterized by an externally threaded opposing ends and a plain tube being made thinner in wall thickness and said plain portion made longer, and a polytetrafluorethylene (PTFE) material coating the internal wall of the lower tube.

Abstract: Advanced oxygen enrichment technologies for Claus plants are presented that provide an oxygen rich gas stream to the Claus burner of the thermal stage and one or more oxygen rich bypass gas streams to at least one of the catalytic stages to so increase the capacity of the plant while reducing the amount of recycle gases needed for flame temperature moderation.

Abstract: Sulfur emissions from liquid sulfur are reduced, or even entirely avoided by degassing the liquid sulfur at pressure in an out-of-pit vessel and by sweeping the rundown pit (or vessel) with a sweep gas that is non-poisonous for a hydrogenation catalyst. Acid gases from degassing are fed at pressure to the Claus unit, while sweep gases are fed to the tail gas treatment unit to substantially recycle the acid gases to extinction. In preferred plants and methods, motive fluids and booster eductors or compressors are not needed, and incineration of the acid gases can be avoided.

Abstract: The present invention is a method to expand sulfur processing capacity for a new or existing sulfur recovery unit. In one embodiment, the method includes passing a process gas stream containing sulfur dioxide over a catalyst capable of oxidation of sulfur dioxide in one or more catalytic stages upstream of a tailgas treatment unit.

Abstract: A toy gun having a barrel and handle supporting a pivoted trigger and spring-pressed hammer engageable with an elongated slide having driving teeth engageable with pinion drive means for a noise-producing unit in said barrel which includes a vibratable spring that produces a sound resembling a ricocheting bullet when said slide is moved forwardly by said hammer after it is moved rearward by said trigger and released to permit the spring to move the hammer forwardly sharply.
