Iron-rich material waste products, such as electric arc furnace dust, are formed with an organic binder into discrete shapes, such as briquettes and/or other solid shapes. The shapes can then be used in iron and steel making processes and the iron and heavy metal values in the waste product recovered.

Process for recovering iron from iron-rich material

A compressed briquette or other solid shape, object, or article useful as a coke substitute in blast furnaces disclosed as being manufactured so as to comprise a reaction product of fine carbonaceous material (such as coke breeze, coke fines, or petroleum coke), a reactive tar, and polymeric binder.

Process for recovering iron from iron-containing material

A method and a solid fuel product, such as briquettes and pellets, comprising carbon fines, in the form of heretofore discardable coke breeze and/or coal fines and/or revert materials, bound together chemically into smaller pieces to substantially prevent degradation and which constitutes a source of high heat without creating significant pollution or smoke.

Iron-rich-material waste products, such as electric arc furnace dust, are formed with an organic binder into discrete shapes, such as briquettes. The shapes can then be used in iron and steel making processes and the iron and heavy metal values in the waste product recovered.

A foamer, and related method, wherein the foamer comprises a container in which a large supply of foamable liquid is disposed. A predetermined amount of foamable liquid is displaced from time to time from the large container to a relatively small capacity pump chamber, under force of manually-created negative pressure. Manually-created positive air pressure displaces a fixed quantity of foamable liquid from the pump chamber as a stream to a foam-creating mixing chamber where a controlled amount of the air under positive pressure is introduced into the stream of foamable liquid to produce effluent foam.

Foamer and method

The foam dispensing device is intended for use in the inverted position and includes a container having a reservoir portion for holding a foamable liquid and a bellows portion for holding air. A foam producing unit is mounted in the discharge port, the foam producing unit including a housing mounted in and receiving air from the bellows and a liquid receiving conduit extending from the foam producing unit into the reservoir. A separate air return conduit communicating with atmosphere extends into the container air. The container reservoir and bellows portions are separated by a finger-engageable waist portion to facilitate operation of the bellows portion.

Foam dispensing device

This foam dispensing device is intended for use in the inverted position and includes a container having a reservoir portion for holding a foamable liquid and a portion for holding air. A foam producing unit is mounted in the discharge port, the foam producing unit including a housing mounted in and receiving air from the air portion and a liquid receiving conduit extending from the foam producing unit into the reservoir portion. A separate air return conduit communicating with atmosphere extends into the container air portion.

This foam dispensing device includes an outer container for holding foamable liquid, and a foam producing unit mounted in the discharge port of the outer container. The foam producing unit includes an inner container of substantial smaller cross section than the outer container, and a closure cap having a pressurized air inlet and foam outlet. A one-way valve is provided between the inner and outer containers which opens to replenish the foamable liquid supply in the inner container but remains closed during the foam forming process.

An arterial blood sampling syringe consisting of a barrel and a plunger assembly in which the plunger is hollow and provided at its distal end with two annular rings which cooperate with the hollow plunger and each other to maintain a sealing ring and gas-pervious but liquid impervious membrane in position at the end of the plunger. The plunger position in the barrel may be preset to receive any desired blood sample volume. Further blood flow is halted when the barrel of the syringe fills to the volume desired.
