摘要:
The present invention is to emulsifiable polyisocyanate compositions comprising the reaction product of (i) an aliphatic polyisocyanate and (ii) an emulsifier wherein the polyisocyanate comprises a mixture of two or more isomers of cis-1,3-bis(isocyanatomethyl)cyclohexane, trans-1,3-bis(isocyanatomethyl)cyclohexane, cis-1,4-bis(isocyanatomethyl)cyclohexane or trans-1,4-bis(isocyanatomethyl)cyclohexane, with the proviso said isomeric mixture comprises at least about 5 weight percent of said trans-1,4-bis(isocyanatomethyl)cyclohexane. The emulsifiable polyisocyanates are particularly in formulations for producing paints and varnishes, coatings, adhesives, impregnating materials and sealants.
摘要:
Isocyanurate polyisocyanates compositions derived from bis(isocyanotomethyl)cyclohexane are disclosed. The compositions are prepared by cyclizing (i) 1,3-bis(isocyanotomethyl)cyclohexane or 1,4-bis(isocyanotomethyl)cyclohexane or (ii) an isomeric mixture of two or more of cis-1,3-bis(isocyanotomethyl)cyclohexane, trans-1,3-bis(isocyanotomethyl)cyclohexane, cis-1,4-bis(isocyanotomethyl)cyclohexane and trans-1,4-bis(isocyanotomethyl)cyclohexane in the presence of a trimerization catalysts, and then deactivating these catalysts. The isocyanurate polyisocyanates can be further modified to contain urethane, urea, biuret, allophanate, imino-s-triazine, uretonimine or carbodiimide moieties.
摘要:
The present invention is to thermally dissociative blocked polyisocyanate composition containing isocyanurate moieties wherein the isocyanurate is the reactions product of bis(isocyanotomethyl)cyclohexane wherein the 5 bis(isocyanotomethyl)cyclohexane is a mixture comprising two or more of cis-1,3-bis(isocyanotomethyl)cyclohexane, trans-1,3-bis(isocyanotomethyl)cyclohexane, cis-1,4bis(isocyanotomethyl)cyclohexane and trans-1,4-bis(isocyanotomethyl)cyclohexane with the proviso the composition comprises at least 5 weight percent of the 1,4-isomer. When blended with a polyhydroxyl compound, such blocked isocyanurate poyisocyantes are 10 particularly useful in powder and solvent-based coatings.
摘要:
A system and method of transferring funds between accounts. A customer (user) sends an ACH transaction request to transfer an amount of funds from a first account of a first financial institution to a second account of a second financial institution. The first financial institution generates a same day ACH transaction to transfer the amount of funds from the first account to a general ledger account of the first financial institution and at the same time or near the same time, the first financial institution generates a next day or more ACH transaction including a transfer of the amount of funds from the general ledger account of the first financial institution to the second bank account of the second financial institution. The next day or more ACH transaction is completed only if the same day ACH transaction is completed.

An obstruction detection system using a safety switch with a plurality of sensors is provided. The sensors include a sensing element molded in a casing and separated from an adjacent sensor by one of a plurality of connectors. A clip has a strip portion and a first attachment arm extending at an angle from the strip portion. A second attachment arm extends from the strip portion. A barb leg is disposed at an angle relative to the strip portion. The barb leg has a first leg end and a second leg end opposite the first leg end with the barb leg connected at the first leg end to the second attachment arm and the second leg end is disposed toward and spaced apart from the strip portion.

Clips for attaching sensors, cables, or other items to doors, such as retrofitted armored vehicle doors, are provided. In one example embodiment, a clip includes a strip portion, a first attachment arm extending from the strip portion, and a second attachment arm extending from the strip portion. A barb leg is disposed at an angle relative to the strip portion and includes a first leg end and a second leg end opposite the first leg end. The barb leg is connected at the first leg end to the second attachment arm, and the second leg end is disposed towards and spaced apart from the strip portion. A cable clamp extends from an end of the second attachment arm opposite the strip portion or an end of the strip portion opposite the first attachment arm.
摘要:
The invention is directed to a method and product produced for directly synthesizing polyesteramides and copolyesteramides, especially self-assembling copolyesteramides, useful for manufacturing self-assembling materials.
摘要:
The present invention provides a vascular conduit device including a deformable flange and complementary securing ring in cooperation for securing the device within an aperture defined in a tissue wall. The present invention further provides a system for implanting such a vascular conduit device in a tissue wall. More specifically, the present invention provides a system including a coring device for defining an aperture in a tissue wall (such as a ventricle and/or a blood vessel) and securely implanting a vascular conduit device therein so as to provide fluid communication between a first and second surface of the tissue wall via the vascular conduit device.
