摘要:
A formulated resin composition for producing a closed cell rigid polyisocyanate based foam is disclosed. The formulated resin composition for use in a polyurethane froth spraying system includes a hydrofluorocarbon blowing agent, a Mannich polyol, at least one additional polyol, a catalyst system, and a surfactant. The formulated resin composition has a hydroxyl content of at least 400 mg KOH/g and a polyurethane foam produced utilizing the formulated resin composition has a closed cell content of at least 90 percent. The formulated resin composition exhibits a zero ozone depleting potential and produces a polyurethane foam that cures faster than conventional sprayed polyurethane foams.
摘要:
A method for generating data with a wrapping machine during wrapping of a load includes measuring a length of packaging material dispensed during wrapping of the load with a sensing assembly on the wrapping machine. The method further includes obtaining a value indicative of a weight of the packaging material per unit of length and determining a weight of the packaging material dispensed on the wrapped load based on the measured length and the obtained value without removing the packaging material from the load. The determined weight of the packaging material is displayed on a display device.

An apparatus for wrapping a load may include a film dispenser for dispensing a film web including a film dispensing drive. The apparatus may also include a rotational drive system for providing relative rotation between the load and the dispenser during a wrapping cycle. The apparatus may further include a controller configured to operatively couple the film dispensing drive and the rotational drive system such that, for any portion of a revolution of the film dispenser relative to the load during the wrapping cycle, the film dispenser dispenses a selected length of the film web corresponding to the portion of the revolution.

A process for regenerating a used acidic ionic liquid catalyst which has been deactivated by conjunct polymers comprising combining the used catalyst, a metal and a Broensted acid which acts a source of hydrogen in a reaction zone under hydrogenation conditions for a time sufficient to hydrogenate at least a portion of the conjunct polymer is disclosed. An embodiment of a process for regenerating a used acidic ionic liquid catalyst which has been deactivated by conjunct polymers comprising the steps of combining the used ionic liquid catalyst, a metal and HCl in a reaction zone under hydrogenation conditions for a time sufficient to hydrogenate at least a portion of the conjunct polymer; removing reaction product from the reaction zone; mixing the removed reaction product with a hydrocarbon solvent in which the hydrogenated conjunct polymers are soluble; allowing the mixture to separate into two phases, a lighter phase which contains the hydrogenated conjunct polymers and a heavier phase which contains a regenerated ionic liquid catalyst; and recovering at least a portion of the heavier phase is also disclosed.

The present invention is directed to novel alkylated aromatic compositions, zeolite catalyst compositions and processes for making the same. The catalyst compositions comprise zeolite Y and mordenite zeolite having a controlled macropore structure. The present invention is also directed to the preparation of the catalyst compositions and their use in the preparation of novel alkylated aromatic compositions. The catalyst compositions of the present invention exhibit reduced deactivation rates during the alkylation process, thereby increasing the life of the catalysts.
摘要:
System, method and apparatus for carrying out isometric exercises for either diagnostic purposes or therapeutic purposes. When employed in a diagnostic mode, the instrument is programmed to carry out standardized diagnostic regimens and during such regimens provides both visual and aural cues, carries out mathematical computations of force values and provides recordation of diagnostic data in archival memory. When employed in a therapeutic mode the apparatus may only be programmed within mandated therapeutic parameter limitations. During therapeutic trials, the user is visually and aurally cued throughout the test sequence and the therapeutic data evolved during the regimen is recorded and recoverable from archival memory.
摘要:
The present invention describes novel compounds of the formula: (Q)d-Ln-Ch, useful for the diagnosis and treatment of cancer, methods of imaging tumors in a patient, and methods of treating cancer in a patient. The present invention also provides novel compounds useful for monitoring therapeutic angiogenesis treatment and destruction of new angiogenic vasculature. The pharmaceuticals are comprised of a targeting moiety that binds to a receptor that is upregulated during angiogenesis, an optional linking group, and a therapeutically effective radioisotope or diagnostically effective imageable moiety. The imageable moiety is a gamma ray or positron emitting radioisotope, a magnetic resonance imaging contrast agent, an X-ray contrast agent, or an ultrasound contrast agent.

The present invention is directed to a zeolite Y catalyst having a controlled macropore structure. The present invention is also directed to a zeolite Y catalyst composite and a process for preparing the catalyst composite. The catalyst composite exhibits reduced deactivation rates during the alkylation process, thereby increasing the life of the catalyst. The present invention is also directed to processes for the preparation of carbonated, overbased aromatic sulfonates, which processes comprise alkylation, carbonation of aromatic hydrocarbons with one or more olefins.
