  • Publication number: 20250051677
    Abstract: The present application relates to the use of a comb polymer comprising repeating units that can be obtained by polymerisation of monomers (a) of formula (I): in which: R1 is a hydrogen atom or a methyl group, X1 is a group chosen from: —O—, —O(AO)m, or —NH—, each group A being independently a C2-C4 alkylene group and m being an integer ranging from 0 to 10, R2 is polybutylene group, and p is equal to 0 or 1, for improving the cold thickening properties of a lubricating composition having a grade (X)W—(Y) according to the standard SAEJ 300 in which x=0, 5 or 10 and y=8, 16, 20, 30 or 40, comprising at least one base oil, the lubricating composition thus obtained having a Gelation Index according to the standard ASTM D5133 of less than 6.

  • Patent number: 7451709
    Abstract: A portable cooler and table assembly that may be easily transported in a single, self-contained unit is disclosed. The assembly may be converted for use as a table for a variety of recreational activities, e.g., dining, drinking, games such as ping pong, beer pong, table hockey, card games, board games, preparation for sporting events and meals. The table and cooler may be permanently attached to each other, or alternatively, the cooler may be detachable from the table. The table may fold or collapse to assist in converting the assembly from a compact, lightweight transportable unit into a fully extended and operable table and cooler. The table surface may contain surface features such as grooves, indentations, nets, game pieces, etc. The cooler may comprise any container that is capable of containing ice or some other refrigeration or heating system, e.g., a conventional 54 quart beverage cooler. Alternatively, the cooler may be replaced with a storage container or other storage device.
