Abstract: Unwanted contaminants or by-products of oily streams can be removed by distillation at reduced pressure and elevated temperatures using an ancillary distilling agent which lowers the boiling temperatures of the impurities. The efficiency of such removal is enhanced by the formation of a true solution of the ancillary agent in the oily stream at the molecular level. To bring about this solution, the ancillary agent in the superheated gaseous state is brought into intimate contact with the oily stream in a mixing vessel or contactor at substantially equal pressures but at slightly differing temperatures. The oil temperature is such as to cause condensation of the ancillary agent, but not to significantly cool the oil.

Abstract: A tangentially gas fired muffle comprises a hinged annular housing defining inner and outer annular chambers divided by a ring of heat resistant perforate or expanded material. The outer annular chamber has inlets in the form of immersion tubes each locating an atmospheric burner, and outlet ports for discharging the products of the previous burner or burners. The perforate or expanded metal ring contains the combustion process in the outer annular chamber and also acts as a radiant for dissipating heat on a circumferential weld of two pipe sections. The gas burners are connected to a control console for supplying the burners continuously with gas at respective high and low flow rates. Solenoid valves, connected to temperature controllers, provide the burners continuously with gas at respective high and low flow rates. Energy regulators control the rate of heating.

A pair of cams are disposed in contact with opposite plungers with the cylinder block disposed therebetween. The cams each have a cam surface for imparting a plurality of reciprocatory movements in one cycle to the opposite plunger in a manner that the moving velocities of the opposite plungers are different from each other in all phase position. The cam surfaces are formed to have sine curves each having two crests and a different stroke. In consequence, the volume of the chamber between the opposite plungers is always varied.

Abstract: A pair of beltless trousers or slacks with a novel means of support, which permit the trousers or slacks to present a distinct and attractive appearance. A pair of trousers in accordance with the present invention relies upon neither belts, elastic or foam elastomer bands nor suspenders for support. Instead, the inner flap of the fly of the trousers or slacks is formed into a large, wide inner tab, tapering from a longer vertical side to a shorter vertical side. The shorter vertical side is detachably connected to the stiffening elements and the curtain liner on the inner wall of the left pocket, that is, the side of the waistband corresponding to the outer flap of the fly. This construction permits utilization of pockets which are connected solely to the curtain liner and stiffening elements, and which open to the top.
