Abstract: A method for transferring a sized clay material for use in drilling fluids that includes providing the sized clay material to a pneumatic transfer vessel; supplying an air flow to the sized clay material in the pneumatic transfer vessel; and transferring the sized clay material from the pneumatic transfer vessel to a storage vessel is disclosed.

Abstract: A method of processing oilfield weighting agents for pneumatic transference including treating a weight material ore with a chemical additive to produce a treated weighting agent and grinding the treated weighting agent to produce a ground treated weighting agent including a substantially homogenized mixture of the chemical additive and a ground weighting agent. Furthermore, the method includes classifying the ground weighting agent by size, discharging the ground treated weighting agent from the mill, and trapping the ground treated weighting agent in a storage vessel. Also, a method of processing oilfield weighting agents for pneumatic transference including grinding a weight material ore in a mill, wherein the grinding produces a ground weighting agent, and discharging the ground weighting agent from the mill.

Abstract: A method for transferring a finely ground weight material for use in drilling fluids including providing the finely ground weight material to a pneumatic transfer vessel and supplying an air flow to the finely ground weight material in the pneumatic transfer vessel. Furthermore, transferring the finely ground weight material from the pneumatic transfer vessel to a storage vessel. Additionally, a method for transferring a finely ground weight material for use in drilling fluids including modifying a particle distribution of the finely ground weight material and sealing the finely ground weight material in a pneumatic transfer vessel. Further, supplying an air flow to the finely ground weight material in the pneumatic transfer vessel and transferring the finely ground weight material from the pneumatic transfer vessel to a storage vessel.

Abstract: An anti-theft locking system surrounds and immobilizes vehicle steering wheels to immunize vehicles against theft and vandalism. The locking system preferably comprises a rigid, circular pan that surmounts the steering wheel and overlies the steering column. In this manner the vehicle air-bag compartment is protected. The pan has a rigid, peripheral rim that coaxially surrounds and ensconces the steering wheel ring. The steering wheel is thus rendered inaccessible to hack saws or cutting tools that are normally used by thieves to remove conventional steering wheel locks. An elongated locking assembly mounted on top of the pan is activated by a removable, elongated, rod that penetrates the locking assembly to fasten the pan on the steering wheel. The locking assembly is protected on top by a substantially tubular, protective shroud, and the lock bottom is protected by a compartment welded to the pan.
