Abstract: A B S T R A C T         Copolymers of glycidol, glycidyl esters of car-boxylic acids and, optionally, alkylene oxides, are prepared by the reaction of a saturated or unsaturated carboxylic acid with a polymer or copolymer of tertiary butyl glycidyl ether in the presence of an acid catalyst.       The polymers prepared from unsaturated carboxylic acids are polymerizable and copolymerizable with vinyl monomers and are useful as curable resins. Many of them can be used to make water-resistant or water-insoluble coatings for metals or other substrates.           The polymers prepared from saturated carboxylic acids are useful as coatings for metals and as surfactants.

Abstract: ABSTRACT     In the production of alumina for supply to electrolytic reduction cells in the production of aluminium metal, alumina trihydrate is calcined in a calcination furnace to convert it to alumina, typically having a water content of less than 2%.  In the course of this operation fine particles in a size range below 44 microns are separated from the exhaust gases from the calciner.  In conventional procedures these particles which are only partially dehydrated, are either recycled to the calciner. or directly added to the calciner product alumina.  With the dual objective of reducing environ-mental pollution and saving valuable alumina the present invention converts these collected fines into compacted granules in a size range of 150-5000 microns for supply to an electrolytic reduction cell either directly or after readmixture with the calciner product alumina.

Abstract: PRESSURE BALANCED METAL TO METAL SEAL      A B S T R A C T          A seal arrangement is provided having a pair of elastomeric seal rings with a seal band adjacent the innermost diameter of the rings.  The seal rings are retained by means of a pair of elastomeric torics, one of which is relatively immovable and the other of which is relatively movable.  The movable toric is positioned between supporting structure incorporating ramps of low angle, which improves the pressure, velocity relationships of the seal and permits operation at higher speeds.  Retention of the other toric stabilizes the seal and prevents cocking or tilting of the rings so as to maintain the sealing plane perpendicular to the rotational axis.  An arrangement is thus provided wherein the seals are of nearly equal surface area which produces pressure balanced seals and a more constant, level force along the axis.

The panels are preferably formed of foamed synthetic resinous composition and of a limited number of configurations or modules which are interchangeably adapted for use in forming pools having a plurality of shapes, e.g. a straight panel, a concave curved panel and a convex curved panel.  Each panel is adapted to mate and lock with the adjoining panel, and with an upper and lower flanges and rib arrangements which serve to strengthen the panel. In a specific embodiment, a tongue is formed on the flange on one side and a mating groove on the flange on the other side of each panel for instant con-necting and interlocking of adjacent panels when they are assembled in forming the pool wall.  A sealing strip may be placed within the groove and abuts on the tongue of the adjoining panel thereby precluding leakage between the panels.  Support is provided for each panel by at least one brace which is positioned to extend normal to or radially from the panel.  A wall panel module may be formed with a horizontally extending slot in the inner wall adjacent the bottom edge of the modulate side panels for receiving and securing a bead of a plastic liner adapted to cover essentially only the bottom of the pool.

Abstract: ABSTRACT OF THE DISCLOSURE A modification is provided in an assembly for use in a well test string during oil or gas tests on exploration wells.  The well has a well bore and a test string with  a subsea test tree located in the vicinity of the subsea blowout preventor at the sea floor.  The modified assembly in-cludes at least one line having one end in communication with a supply of methanol and the other end in communication with the test string below the sea floor. The line is substantially parallel to the test string and in-cludes the following combination: upper and lower external tubing protectors mechanically associated with the external tubing and the production string; internal porting of selected sections of the subsea test tree, thereby not interrupting the functional use of any component; a pin and box connector connecting the upper external tubing to  the upper internal portion; and a lower methanol injection check valve disposed below the sea floor for ad-mitting methanol into the test string while providing a bubble-tight seal against well fluids. The invention thus provides a method of preventing hy-drate plug formation in production testing of oil and gas wells by injecting methanol into the test string of the well at any desired depth at an in-jection rate of at least 1.0 g pm.
