Appl. No.:

11/073068

Inventors:

Peter Song - Fullerton CA, US

International Classification:

G01F 11/00

US Classification:

222262, 222333, 1841052

Abstract:

A grease gun plunger for a grease gun having an oil injection channel includes a motor driving unit, a plunger unit, and a yoke. The plunger unit includes a bracket having a bracket cavity and an elongated slot longitudinally formed on a rear wall of the bracket to communicate with the bracket cavity, and a plunger pin downwardly extended from the bracket for slidably inserting into the oil injection channel. The yoke, which is substantially held in the bracket cavity of the bracket, has a sliding channel aligning with the elongated slot of the bracket, wherein the driving shaft is slidably inserted into the sliding channel through the elongated slot in such a manner that when the driving shaft is rotated to slide along the sliding channel, the yoke is driven to move in a reciprocating manner along a transverse direction.

Abstract:

In a continuous process for recovery of liquid hydrocarbons from a solid carbonaceous material by pyrolysis of the carbonaceous material in the presence of a particulate source of heat, particulate contamination of the liquid hydrocarbons is minimized. This is accomplished by removing fines from the solid carbonaceous material feed stream before pyrolysis, removing fines from the particulate source of heat before combining it with the carbonaceous material to effect pyrolysis of the carbonaceous material, and providing a coarse fraction of reduced fines content of the carbon containing solid residue resulting from the pyrolysis of the carbonaceous material before oxidizing carbon in the carbon containing solid residue to form the particulate source of heat.
