Abstract: Apparatus for unloading a top unloading mine car that is mounted to pivot about a horizontal axis extending along one side of the base of the mine car includes a hoist chain detachably connected to the mine car at the side opposite the pivotal axis. The hoist chain extends upwardly over a pulley mounted on a positioning crank arm. The pulley moves on rotation of the crank arm from a position substantially vertically above the connection means when the mine car is in an upright position to a position above the pivotal axis. The hoist chain continues around a pulley mounted on a drive crank arm and then to an attachment of restricted mobility. The drive crank arm and the positioning crank arm are rotated in a single direction by drive means which are adapted to rotate the drive crank arm at twice the angular velocity of the positioning crank arm.

Abstract: Apparatus is provided for blending batches of particulate material that are compositionally heterogeneous into batches of material that are compositionally uniform. The apparatus consists of two vertically aligned cylindrical mixers, including means to transfer product from the first mixer to the second mixer. Each mixer contains six or more vertically aligned partition walls that extend radially from the midpoint of the mixer to the wall to divide the mixer into at least six storage compartments of substantially equal volumetric capacity. The vertical partition walls differ in height in a regular descending order so that as material is charged to and fills one compartment, it overflows the shorter wall to fill the adjacent compartment.

Abstract: Boron trifluoride contaminant is removed from organic liquids by contacting the contaminated liquid with polyvinyl alcohol. For example, boron trifluoride catalyst is removed from 1-olefin oligomer product by passing the liquid oligomer through a bed of granular polyvinyl alcohol.

Abstract: The antifriction properties of a lubricating oil are enhanced by the addition of a minor amount of an oil-soluble molybdenyl bis-.beta.-diketonate. The antifriction properties are particularly enhanced when the molybdenyl bis-.beta.-diketonate is used in combination with an oil-soluble active sulfur donor, such as a zinc dialkyldithiophosphate.

Abstract: The combustible component of a gas stream of low heating value is combusted using less than a stoichiometric amount of oxygen under conditions for the suppression of carbon monoxide including the presence of an oxidation catalyst and a small amount of arsine, and the heat energy in the combusted gas is utilized, for example, by expansion in a gas turbine.

Abstract: Novel resin products produced by reacting unique polycyclic, aromatic, polycarboxylic acid products with low molecular weight polyols display satisfactory toughness properties and good Barcol hardness values. The process for preparing these novel resin products first involves preparing an intimate, finely divided mixture comprising the acid product derived from the nitric acid oxidation of naturally occurring solid carbonaceous material, a roughly equivalent amount of a liquid polyol, and a suitable acid catalyst. The mixture is then subjected to a precure step which involves heating at temperatures between 80.degree. and 150.degree. C. for from about fifteen minutes to about four hours. The precured mixture may thereafter be subjected to suitable molding conditions at a temperature below about 220.degree. C.

Abstract: A modified in-situ retort for the retorting of oil shale is constructed by mining an open space having a volume of twenty-five to thirty-five percent of the volume of the retort in the bottom of the retort and thereafter blasting the oil shale that is to remain in the retort as rubble in a manner to cause random free fall of the shale particles onto the rubblized bed. Blasting occurs sequentially from the bottom of the unfragmented shale immediately above the open space to the top of the retort. At each blast, there is an open space below the shale to be broken in the blast having a volume at least one-third the volume of that shale, and the timing of the blasts is such that movement of the broken shale is not interfered with by shale broken in the preceding blast. There is no withdrawal of oil shale that would cause downward movement of the rubble that is to be retorted in-situ. The resultant in-situ retort is characterized by a high and uniform permeability.
