A method and product is disclosed which provides emulsion stability and filtration control to invert emulsion drilling fluids. The product comprises a blend of a carboxylic acid terminated polyamide and / or a wetting agent with a reaction product or mixture produced by the Diels-Alder reaction of dienophiles, preferably carboxylic acids, polycarboxylic acids, acid anhydrides, or combinations or mixes thereof, with a mixture of fatty acids and resin acids. The product of the invention is extremely effective, decreasing by about two-thirds the amount of emulsifier generally required to formulate an effective drilling fluid. The product of the invention also greatly reduces and in many cases eliminates the need for conventional fluid loss additives, and additionally provides electrical stability. Moreover, the product of the invention has a pour point as low as about 20 degrees Fahrenheit with minimal solvents, thereby eliminating the need to ship large amounts of inert material for use, and may be transported in a highly active state.

A panel for polypropylene injection molded siding, and for similar materials and / or uses, is mounted in lapped courses with panels attached at butt joints in a direction of elongation. Complementary tabs and slots at the panel ends can be engaged by end-to-end approach of the abutting panels. Additionally, openings for the tabs permit engagement from a position in which the panel ends are already overlapped, which reduces or eliminates the need for endwise assembly space. The slots can be discontinuous on one or both sides, openings permitting lateral insertion of the tabs at gaps, whereupon movement of the tabs along the slots engages the joint. The panels can simulate wood siding and include a step between simulated courses. A gap is provided in the edge of the panel at the step, thus forming an opening for the tab to enter and move along the slot.

A vehicle safety seat (104, 202, 302, 502, 802) includes a seat bottom (120, 210, 310, 504, 810) that is movable substantially instantly from a substantially horizontal normal orientation for normal traveling to a deployed angled orientation contemporaneously with a vehicle crash. The deployed safety seat shifts a seat occupant (102) into a protective posture to reduce accelerations, loads and moments of force on various parts of the occupant's body. In preferred embodiments, the seat bottom is deployed into its angled orientation by lowering the rear (124, 312, 507, 812) of the seat bottom, causing the seat bottom to pivot about a front pivot (174, 220, 320, 518, 820) at the front of the seat bottom. Typically, a vehicle safety seat includes a backrest (130, 240, 360, 550, 840). In some embodiments, a backrest (130, 240, 360, 550) is movable downwards and / or rearwards simultaneously with movement of the seat bottom.

A structure including at least two structural components arranged to form a channel therebetween, a post tensioning element configured to compress the at least two elements with respect to each other, and a thixotropic filler material located within the channel.

An intervertebral joint prosthesis having a ball component (22) for engagement with a first vertebra (26) and a trough component (24) for engagement with a second vertebra (27) adjacent to the first vertebra is disclosed. The trough component (24) includes a generally concave surface (50) having a substantially flat portion (52). When the ball component (22) and the trough component (24) are engaged to their respective vertebrae, the ball component (72) and the trough component (24) engage each other, permitting rotation and translation of the vertebrae with respect to each other. Both components include a flange (34,56) for engaging a vertebra. The invention also contemplates a method for and a tool for use in implanting a two-piece intervertebral joint prosthesis.
