Abstract: ABSTRACT OF THE DISCLOSURE An apparatus is disclosed for immediate ignition of waste gases and their smokeless burning which is built into a cylindrical stack, for the flow of waste gases.  Near the top of the stack there is positioned, coaxially, a steam-air pipe for supplying a mixture of steam and air.  The steam and air are introduced into the pipe by means of radial tubes connected to a circular mani-fold on the outside of the stack.  A circular cover plate or baffle over the steam-air pipe is supported by a plurality of broad strips equally spaced circumferentially, around the periphery of the steam-air pipe.  There are a plurality of radial support arms between the stack and the steam-air pipe. These can be made from angle iron of sufficient width, the purpose being to deflect upwardly the flow of the annular column of gas, to break it into a plurality of spaced circular segments of gas.  The space above the arms protects a stable flame for instant reignition of the mixture of gas, air and steam.

Abstract: ABSTRACT        A handle for use on a bucket of plastic material and a fastening knob are integrally moulded and interconnected by a moulded fin.  The fastening knob has a head, an elastically resilient flange slanting outwards, and a shank.  When the handle is to be attached to a bucket, the free end of shank is connected to the bucket wall, preferably by ultrasonic welding, and handle is pressed towards said wall.  Head is pressed through an aperture in the handle to pivotably mount the handle on the shank, with flange acting as a barb-like anchoring member preventing the handle from falling off.  Simultaneous moulding of the handle and the fastening knob renders the use of lateral core removing openings superfluous and simplifies mounting of the handle and the knob.

The upper end of the anchor has a relatively deep wrench socket for rotation of the anchor and for reception of a companion pillar part.          The pillar part is made of slightly flexible plastic material that can approximate a prepared tooth to serve as a single tooth replacement or as a support for a fixed bridge.  Optionally, the pillar can provide a platform that forms or mounts one of two companion elements of a connector structure such as for overdenture retention.  The anchor can be altered in length not only at the bottom, but also at the top, without changing the manner in which the anchor cooperates with the later placed pillar.

Abstract: HEC-BENTONITE COMPATIBLE BLENDS                 ABSTRACT OF THE DISCLOSURE     Drilling fluids, both fresh and saline, containing additives and compositions, predominantly nonionic in nature, for the beneficiation of bentonite in such drilling slurries.          The primary class of compounds employed are ethylene oxide derivatives, nonionic polysaccharides and under certain specified conditions anionic polysaccharides.  In fresh water slurries polyethylene glycol derivatives of significantly different molecular weights are employed with nonionic poly-saccharides for optimizing the rheological characteristics of bentonite slurries.  The anionic polysaccharide can be deleted from the blend for economic reasons.  In such formulations (i.e., a polyethylene glycol-nonionic polysaccharide blend) the molecular weight of the polyethylene glycol is important in obtaining low shear-rate yield stress characteristics in fresh water slurries, at elevated temperatures for maximum drill solids carrying capacity within the wellbore.  The blend of beneficiating agents affects a decreasing yield stress character with decreasing temperature to permit drill solids removal at ambient surface conditions.  In saline solutions polyethylene glycols of intermediate molecular weight (less than 30,000) and nonionic polysaccharides are effective in inhibiting syneresis (i.e., phase separation) and in providing good slurry rheological profiles at elevated temperatures.  Anionic poly-saccharides are utilized (particularly in saline solutions) to ensure the proper structuring of the bentonite wellbore filter cake for fluid loss control and to ensure optimum rheological characteristics of the slurry with the ternary blend of beneficiating agents at intermediate reservoir temperatures.
