Abstract: An apparatus is described for applying a liquid to treat the nap and backing of a rug or carpet. The applicator having a cylindrical body enclosing a hollow reservoir with teeth extending from inside the reservoir outwardly through the body such that the nap of the rug is penetrated to apply liquid to the backing of the rug. The teeth and, optionally, the cylindrical body are porous, allowing the treating liquid to migrate from the reservoir to the surface to be treated as the apparatus is moved across the surfaces.

Abstract: An apparatus and process is described whereby a sour hydrocarbon distillate stream is treated in two oxidation zones within the same reaction vessel to oxidize mercaptans. The initial treatment is in the presence of a fiber bundle and the subsequent treatment over a bed of supported oxidation catalyst.

Abstract: A comb is disclosed that may be used for applying liquid to both scalp and hair and which may is effective regardless of the orientation of the comb. The liquid is retained in the comb in a porous wick-like material and the liquid dispensing teeth are a porous wick-like material so that capillary action ensures a continuous, regulated flow of liquid regardless of the orientation of the comb.

Abstract: A hydropneumatic cable tensioner is comprised of an enclosed cylinder featuring a plurality of annular chambers. A fixed cable sheave is mounted to one end of the cylinder. A movable cable sheave is mounted to a piston rod connected to a piston which reciprocates in the innermost or piston bore chamber of the cylinder. Regulated compressed gas is connected to the outer chamber of the cylinder thereby exerting high pressure forces on oil found in the middle or high pressure oil chamber of the cylinder. Pressurized oil forces a piston to move outwardly thereby increasing the distance between the two sheaves and tensioning a cable. Restriction means within the piston bore chamber regulate movement of the piston and prevent uncontrolled acceleration should a cable failure occur.
