A play pen has a frame and a fabric substrate defining an enclosure and has a main body. The frame has a plurality of legs and a central post. The main body has an entrance, a plurality of storage pockets, and a display pocket. The entrance has a first fastener. The plurality of storage pockets defines a first pocket formed between the main body and a storage sheet. The storage sheet is sewn to the main body on a first edge and secured to the main body on a second edge by a second fastener. The display pocket defines a second pocket formed between the main body and a transparent or translucent cover sheet. The cover sheet is sewn to the main body on a third edge and secured to the main body on a fourth edge by a third fastener, and faces the enclosure.

A gate assembly that comprises a support assembly and a gate. The support assembly comprises a first support, a second support, and a base positioned between the first support and the second support. The base comprises a first flange adjacent a first end of the base and a second flange adjacent a second end of the base. The first flange is positioned within the first support and the second flange is positioned within the second support. The gate comprises an upper rail, a lower rail, and a plurality of posts disposed orthogonally with respect to the upper rail and the lower rail. The plurality of posts are removably engaged with the upper rail and the lower rail. The gate is rotatably attached to the support assembly. The first flange is removably attached to the first support and the second flange is removably attached to the second support.

The present invention is a method of integrating oxygen production with blast furnace operation. A heated air stream is introduced to an ion transfer membrane separator, producing a permeate and a retentate. The permeate and the motive stream are introduced into an ejector jet pump producing an oxygen enriched stream. The oxygen enriched stream is introduced into blast furnace. In another embodiment of the present invention, the permeate and a steam motive stream are introduced into an ejector jet pump. Heated air inlet stream is introduced into a cascading series of ion transfer membrane separators, producing a series of permeate streams and a series of retentate streams wherein each retentate stream acts as the input stream for the subsequent ion transfer membrane separator. Thereby producing a series of oxygen enriched streams which are combined and introduced into blast furnace.

A simple, compact burner achieves a more optimal melting of a solid charge followed by performance of combustion under distributed combustion conditions. The burner achieves this by fluidically bending the flame towards the solid charge during a melting phase with an actuating jet of oxidant, redirecting the flame in a direction away from the charge, and staging injection of oxidant among primary and secondary portions during a distributed combustion phase.

Method for melting a solid charge

A child safety lock for a lever door handle is rotatably mounted on a first side of a door and is biased in a first position. The child safety lock has a holder adapted to engage the door handle so that rotating the door handle rotates the holder. A cover is pivotally mounted on the holder and is shaped to cover the holder. A lock assembly is disposed in a vicinity of the door handle. The lock assembly selectively engages the cover for preventing rotation of the cover.
