A trash can assembly has a shell having a bottom end, a base secured to the bottom end and a foot pedal assembly coupled to the base. The foot pedal assembly has a pedal bar pivotably secured to the base, and a foot pedal. The foot pedal can be separated from the pedal bar before placing the trash can assembly inside a containing box.

The present invention relates to methods of stimulating a subterranean formation. More particularly, but not by way of limitation, the present invention relates to methods of fracturing subterranean formations utilizing a fracturing fluid comprising a permeable cement composition that may be used as a propping agent. One method of stimulating a subterranean formation of the present invention comprises the following steps: preparing a permeable cement composition comprising a hydraulic cement, wa...

The present invention is directed to a low cost method and apparatus for fracturing a subterranean formation. The invention involves using a centrifugal pump to combine a fracture fluid, a sand suspension and liquid additive and discharge a mixture of these components into a high pressure pump that injects the mixture into the subterranean formation. The apparatus employs a control pinch valve to precisely control the amount of sand suspension being added to the mixture. The apparatus eliminates...

While the manufacturing of integrated circuits (IC) has become a mostly automated process, the loading of the ICs into storage and shipping tubes 105 still requires a large amount of human interaction. A major stumbling block to the automation is the removal and insertion of retention pins 115 in the tubes. The present invention uses pressurized air 406 to hold a partially extracted retention pin 115 in position while the tube 105 is loaded. Once loaded, the retention pin 115 is reinserted. By n...

A bag filling and sealing machine includes a bag holder, a bag opening and filling station, and a sealing station. The bag holder holds wicketed bags in a manner that allows the bags to be easily torn from the holder. A funnel assembly successively opens each bag, tears the bag from the bag holder, fills the bag with material, and releases the bag to a grabber assembly. The grabber assembly engages the sides of the bag while the bag is attached to a funnel assembly and later pulls the sides of t...

A novel apparatus and method of automatically stuffing folder pockets includes providing a folder with one or more pockets; providing one or more inserts which can be of differing sizes; the accumulation of the one or more inserts in a stack for insertion into the one or more pockets of the folder; opening the one or more pockets of the folder; and the insertion of the accumulated stack of the one or more inserts into the one or more folder pockets. Predetermined inserts can be selectively proce...

In an opening-closing mechanism of a door member for shifting the door member from a closed position for closing an opening portion of a base member to an open position and vice versa, the door member includes a pair of arm portions. Each arm portion includes a circular arc shape gear and a rotary gear disposed in a center of the circular arc of the gear. The base member includes a first fixed gear portion with internal teeth engaging the circular arc shape gear portion, and a second fixed gear ...

A trash can assembly has a shell, a liner fitted inside the shell, a lid fitted over the top end of the shell, a foot pedal positioned adjacent the bottom end of the shell, a link assembly coupling the foot pedal and the lid, and a support block provided adjacent the bottom end of the shell for supporting the liner in a raised position with respect to the shell. In use, the user can fit a trash bag inside the liner, and then seat the liner inside the shell. To replace the trash bag, the user can...

The present invention relates to fluid systems comprising a first fluid comprising carbon dioxide and a second fluid comprising an alkaline crosslinked fluid. The fluid combinations of the present invention may be used, for example, in hydraulic fracturing, frac-packing, and gravel packing. Some embodiments of the present invention provide systems for treating a subterranean formation comprising a first fluid comprising a foamed carbon dioxide fluid, an emulsion of carbon dioxide, or a carbon di...

A stack of object is wrapped by first transversely outwardly stretching a tube having open ends and then pulling the transversely outwardly stretched tube over the stack to a position with the tube extending generally a full length of the stack and one open end of the tube projecting past an end of the stack. Then the tube is released such that it retracts into engagement with sides of the stack and the one open tube end bears on the end of the stack at least adjacent edges of the end of the sta...
