A polyurethane foam article comprises a first lift, a second lift, and a pass-line therebetween. The polyurethane foam article comprises the reaction product of an isocyanate-reactive resin composition, an isocyanate, and an indicator dye in the presence of a blowing agent. The indicator dye imparts a color in the first and second lifts and at the pass-line at a first temperature below a decomposition temperature of the indicator dye. The indicator dye chemically decomposes to impart a change in color in the first and second lifts and at the pass-line at a second temperature which is at or above the decomposition temperature of the indicator dye.
摘要:
A polyurethane foam and a resin composition that may be used to form the polyurethane foam are provided. The resin composition includes a first polyol based upon ethylene diamine and having about 100% ethylene oxide capping and present in an amount of from about 0.3 to about 15 parts by weight based on 100 parts by weight of the resin composition, a second polyol, and a physical blowing agent having at least 4 carbon atoms. The polyurethane foam includes the reaction product of an isocyanate component and the resin composition comprising the first and second polyol, in the presence of the physical blowing agent. A method of forming the polyurethane foam on a substrate combines the isocyanate component and the resin composition to form a reaction mixture. The reaction mixture is applied onto the substrate to form the polyurethane foam.

A stemless ball valve comprising a first flange, second flange, ball, inner magnetic cartridge, outer magnetic cartridge, and planetary gear assembly. The inner magnetic cartridge is situated inside of the outer magnetic cartridge, and the inner and outer magnetic cartridges actuate the valve. The planetary gear assembly is situated between the inner magnetic cartridge and the ball. The planetary gear assembly comprises one or more planetary gear phases, each planetary gear phase comprising a step-down gear. Each planetary gear phase comprises one or more planetary gears that engage with the inner teeth of the outer ring of the planetary gear assembly and with a step-down gear. The invention further comprises a pressure equalization system comprising inner and outer equalization tubes, a piston situated between the inner and outer equalization tubes, and either a piston spring or spring washer stack that biases the piston in the direction of the clean oil.

摘要:
A stemless ball valve comprising two flanges and a ball with a channel, two axis pins and two travel pins. One end of each axis and travel pin is fixedly attached to the ball, and the other end of each axis pin is lodged into a notch in the first or second flange such that the axis pin is allowed to rotate in the notch. The guide sleeve comprises two channels, and one end of each travel pin is situated within one of the two channels in the guide sleeve. An outer magnetic cartridge causes the inner magnetic cartridge and guide sleeve to rotate, and when the guide sleeve rotates, the travel pins move up and down within the channels in the guide sleeve. The movement of the travel pins within the channels in the guide sleeve causes the ball to rotate, thereby opening and closing the ball valve.

Monovalent compounds having moieties comprising at least one amino acid side chain are bound to a core molecule, which also comprises a nucleophilic moiety bound to said core molecule. Monovalent compounds also comprise a macrocyclic ring, a nucleophilic moiety, and a spacer group. Monovalent compounds may be combined into bivalent and trivalent compounds, some of which may have a labeling tag. Methods of production of bivalent compounds and contemplated uses thereof are disclosed.
摘要:
Proteolytically stable small molecule β-turn peptidomimetic compounds have been identified as agonists or antagonists of neurotrophin receptors, such as TrkA. A compound of particular interest binds the immunoglobulin-like C2 region of the extracellular domain of TrkA, competes the binding of another TrkA ligand, affords selective trophic protection to TrkA-expressing cell lines and neuronal primary cultures, and induces the differentiation of primary neuronal cultures. The small β-turn peptidomimetic compounds of the invention can activate a tyrosine kinase neurotrophin receptor that normally binds a relatively large protein ligand. Such compounds that bind the extracellular domain of Trk receptors are useful pharmacological agents to address disorders where Trk receptors play a role, by targeting populations selectively.
