Square mechanism

Diamond Square Pitch. Popular arrangement for reasonable low-pressure drop (not as low as in-line square), mechanical cleaning requirements, and better coefficient than in-line square pitch.

Depalletizers. Depalletizers are highly specialized pieces of equipment which automatically depalletize cartons and cases. Automatic squaring mechanisms permit the handling of loose pallet loads. Depalletizers generally operate in the range of 3500 cases per hour and are seen primarily in beverage distribution. 

The Schrock complex W H - u NAr O- - u, previously mentioned section. as an alkene metathesis catalyst, also initiates the polymerization of acetylene in toluene in the presence of quinuclidine with metallacyclobutene formation followed by opening of the metallacyclobutene, which again confirms the metallo-square mechanism. This polymerization can be controlled if a limited amount of acetylene 3 to 13 equivalents is introduced. The polyenes are formed...
