Abstract: Disclosed herein are fired ceramic wares possessing hydrophobic properties throughout the bodies thereof. The ware is prepared utilizing a water-reduced ceramic body composition containing a quantity of a finely-divided sub-micron amorphous silica or alumina. This ceramic body composition is formed into a green ware, the ware dried and fired at relatively low temperature and the fired ware treated with one or more reactive organosilicon compounds whereby organosilicon groups are caused to chemisorb onto the surface of the finely-divided amorphous oxide component.

Abstract: There is disclosed a method for dyeing avian eggs whereby a pleasing decorative mottled appearance results. The method involves the temporary application of a hydrophobic granular water-insoluble solid to the eggshell followed by dyeing of the egg utilizing a conventional aqueous dyestuff. The granular solid is removed from the egg following the dyeing step.

Abstract: There are provided water-repellent compositions comprising hydrophobic, finely-divided particulate metal or metalloid oxides. The compositions of the invention are useful in imparting water-repellent properties to porous substrates coated therewith.

Abstract: A wet pelletizing process for preparing improved carbon black pellets having controlled size, uniformity and bulk handling properties, wherein fluffy carbon black is intimately mixed with a portion of the liquid medium required for pellet formation prior to adding the remainder of the liquid medium during pelletization.

Abstract: There is disclosed herein a mobile well drilling rig apparatus adapted for rapid assembly and disassembly thereof. The drilling rigs of the invention comprise a trailerable telescoping mast assembly and a separate sectionable substructure assembly therefor comprising a rig base, a working floor mounted in spaced relation above the base and a rig base extension extending outwardly from the drawworks side of the rig base. In a preferred embodiment, rail means defining a mastway are provided between the erected working floor and the rig base extension. The base mast section of the telescoping mast assembly is provided with cooperative mast roller means whereby the base of the mast structure is readily conveyed to the working floor and whereby the drawworks side mast legs are engaged into a trunnion arrangement therefor. Means are also provided for raising of the mast structure to the vertical from the drawworks side of the rig.
