An apparatus and a method are provided for uniformly conditioning a polishing pad over the entire surface. The conditioning is achieved by contacting the entire polishing surface of the polishing pad with a polishing pad conditioner having a surface area larger than that of the polishing pad.

A method and apparatus for the conditioning of articles. According to one aspect of the invention, a conveyor conveys articles in a conveying direction along a path. A rotatable belt assembly extends adjacent to the path. The rotatable belt assembly includes a belt having a conditioning run extending generally in the conveying direction to contact articles being conveyed along the path. The belt is mounted so that it is capable of displacement to vary the spacing of the conditioning run from the...

A conditioning apparatus for conditioning a treated fluid includes a conditioning chamber for containing a flow of a treated fluid and an exchange element disposed within said conditioning chamber having one or more fluid passages formed therein filled with a saline solution. The exchange element has a semi-permeable membrane that allows fluid transfer between said treated fluid and said saline solution through said semi-permeable membrane.

The particles of a continuous tobacco stream are conditioned during transport through a vibratory conveyor having a bottom wall located above a stationary chamber which receives conditioned air from one or more blowers. The bottom wall is formed with apertures through which the air passes across the tobacco stream in the form of pulsating currents which agitate the particles of the stream to insure a pronounced energy exchange between tobacco particles and air. The currents pulsate due to vibrat...

An agricultural implement for conditioning a crop comprises a plurality of beaters mounted for rotation about a common axis a cutter for cutting a crop, and mounting structure for mounting the beaters and cutter, during a cutting operation, in co-operating relationship such that the beaters engage crop cut by the cutter before said cut crop falls to the ground, and condition the crop. The cutter may be a horizontal reciprocatory cutter mounted across the line of travel of the implement, or may b...

A travelling carriage carrying a motor driven grinding wheel at the end of a pivoted arm reciprocates back and forth along a steel slab workpiece. A hydraulic cylinder forces the wheel down against the workpiece, this downward movement being controlled in accordance with the power being supplied to the motor and the speed of reciprocating travel of the carriage. Control of the contact pressure of the wheel is thus based on the power being absorbed by the motor, which ensures a substantially cons...

A conditioning composition comprising from 60 to 80% by weight of a diamagnetic mineral source, from 20 to 40% by weight of a paramagnetic basalt, from 2 to 5% by weight of a bonding agent, and from 1 to 20% by weight of a mixed colloidal mineral source.

Compositions and methods for ballistic conditioning firearm projectiles, firearms, and firearm components such as bores of barrels, by applying to such items a conditioning composition selected from the group consisting of hexagonal boron nitride, graphite, tungsten disulfide, antimony trioxide, talc, mica, and mixtures thereof, suspended in a carrier comprising a volatile solvent, and a binder selected from the group consisting of cellulosic-, alkyd- and acrylic-resins.
