Filed: 1992-11-20
Abstract: Title:  METHODS OF PREPARING SINTERED SHAPES AND MethodS         USED THEREIN                        Abstract of the invention The invention relates to a method of preparing sintered shapes, comprising the steps of forming a green body from a mixture comprising (A) a major amount of at least one inorganic powder with (B) at least one reaction product of an amine other than an alkanolamine with a hydrocarbyl-substituted carboxylic acylating agent or alkylalkyleneglycolacetic acylating agent; provided the reaction product is other than an alkylene oxide treated fatty monocarboxylic amide and provided that when the hydrocarbyl-substituted carboxylic acylating agent is a nonaromatic acylating agent, then the hydrocarbyl group is other than hydrocarbyl groups having an average of about 55 to about 110 carbon atoms; and sintering the body. Sintered shapes made from the methods of the present invention have relatively high fired densities and small uniform grain sizes; and low porosity. The reaction products of the present invention help disperse the inorganic powder. These reaction products improve deagglomeration of the inorganic powder and help prevent reagglomeration of the powder.

Title: Low temperature thermal upgrading of lateritic ores
Inventor: DIAZ CARLOS M
IPC: C22B23/02
Filed: 1992-12-01
Abstract: LOW TEMPERATURE THERMAL UPGRADING OF LATERITIC ORES   ABSTRACT   The invention relates to a thermal upgrading process whereby nickel-containing limonite or limonite/saprolite blends are pelletized with requisite amounts of solid carbon reductant and a sulfur-bearing concentrating agent. The pellets are fed to a reactor where they are gradually heated, causing reduction of the metal values. The reduced pellets are then held in a "metallics growth zone" of the reactor at a temperature high enough to allow for liquid-phase migration of the metallics within the pellets but below the point at which the pellets become sticky. The metallics growth zone is provided with a carefully controlled combustion gas atmosphere equivalent to about 60-65% aeration of partial combustion of natural gas which prevents further reduction or re-oxidation and thus provides a good environment for metallic particle growth. After a sufficient retention time, the pellets are then rapidly cooled to prevent the disproportionation of wustite to magnetite. The cooled pellets are then ground and the magnetic fraction separated.

Title: Child-resistant closure with visual close/open indicator
Inventor: BUONO CAETANO
IPC: B65D50/04
Filed: 1992-08-05
Abstract: ABSTRACT            A child-resistant screw-on closure is provided with the closure having a closure state indicating pattern and formed as a three-element closure. The outer cap is arranged for rotation relative to the centrally located middle cap and cooperates in a torquing manner with the middle cap so that, as the closure is rotated lo close the container, an indication of full sealing is viewable through a window of the outer cap only when such sealing is complete. Similarly, during rotative unsealing or opening of the container, the outer cap is the first to move relative to the remainder of the closure so that the indication of complete sealing of the container is no longer viewable through the window just as soon as rotative opening of the container has begun. Thus, the closure provides the user with a readily apparent indication as to whether the container closure is in its fully closed or container-sealing condition.
Patent CA-2088063-A1 (CA)
Title: Coating composition and methods of use
Inventor: VAN WINCKEL WALTER
IPC: C09D5/20
Filed: 1991-07-23
Abstract: A differential adhesion coating composition (DAC) is provided herein. Such DAC composition is first applied to trim material which is to be subsequently painted without regard to covering adjacent glass. The DAC composition is characterized by high adhesion to wood, metal, plastics and painted surfaces and at the same time by selective low adhesion to glass surfaces. After the painting operation of the window frame is completed, the dried DAC composition may be easily scraped, peeled, or otherwise lifted from the glass, together with any paint overlay thereon. When subjected to shear forces of pulling and scraping, the cohesive properties of the DAC composition, when considered in combination with a relatively low adhesion to glass, allows the dried DAC  composition, to be removed in long continuous strips rather than fracturing into small pieces.  Also, the DAC can be used directly as a paint, so that any paint which is inadvertently applied to glass during a painting operation can be subsequently lifted off the glass.

IPC: C09K23/42
Filed: 1993-05-28
Abstract: A corrosion inhibitor with excellent film forming and film persistency characteristics may be produced by first reacting C18 unsaturated fatty acids with maleic anhydride or fumaric acid to produce the fatty acid Diels-Alder adduct or the fatty acid-ene reaction product.  This adduct or reaction product is further reacted in a condensation or hydrolysation reaction with a polyalcohol to form an acid-anhydride ester corrosion inhibitor.  The ester may be reacted with amines, metal hydroxides, metal oxides, ammonia, and combinations thereof to neutralize the ester.  Surfactants may be added to tailor the inhibitor formulation to meet the specific needs of the user (i.e., the corrosion inhibitor may be formulated to produce an oil-soluble, highly water-dispersible corrosion inhibitor or an oil-dispersible, water-soluble corrosion inhibitor).  Suitable carrier solvents may be employed where needed to effectively disperse the corrosion inhibitor formulation.

Title: Method and apparatus for separating c4 hydrocarbons from a gaseous mixture
Inventor: TANGUAY DENNIS C
IPC: F25J3/06
Filed: 1993-10-07
Abstract: Abstract of the Disclosure A  method of and apparatus for separating C4 hydro-carbons from a feed comprising a gaseous mixture.  The feed is cooled and partially condensed in a plurality of successive stages  of condensation and phase separation.   A gaseous overhead from each separation stage is further cooled and supplied to the next separation stage and the liquid separated from each stage is used to cool the gas.  Further refrigera-tion is supplied to the gas to effect the condensations by indirect  heat  exchange  with  a  closed  cycle  refrigerant subjected to a compression/expansion cycle.  The feed under-goes  no  compression  and  no  abrupt  expansion  during  the separation, so that the feed undergoes a pressure decrease due only to friction of the passage of the feed through the apparatus.  The pressure loss is no more than about 20 psi.          The temperature of the feed is maintained below 150°F at all times, to prevent polymerization of 1,3-butadiene.  A mixed refrigerant passes through the closed refrigeration cycle and contains, in decreasing order of plentitude, propane, ethyl-ene,  isopentane and nitrogen.   The mixed refrigerant is subjected to a single compression followed by cooling and phase separation.  The phases of the mixed refrigerant thus separated are separately cooled and expanded and the material thus produced by expansion is used to cool the feed.   :

Abstract: A supporting structure (11) for positioning a product within an outer shipping container takes the form of a plastic air bladder shaped on one side to provide a cavity (13) having internal dimensions maching external dimensions of the product and shaped on the other to have external dimensions matching internal dimensions of the shipping container. The air bladder may be either a vertical or a horizontal positioning element and is typically used in pairs within a single container. The air bladder is compact and can be discarded after use with minimal environment impact. In examples shown, the air bladder is of a plastic material such as polyethylene and is produced by blow molding, making it particularly suitable for disposal after use by a recycling process, thereby further reducing potential environmental impact.
