摘要:
The cycle time of polymer compositions subjected to a rotomolding process is improved (i.e., reduced), while the processing window is simultaneously enlarged through the use of a polymer-stabilizing amount of a processing stabilizer system having at least one chroman-based compound according to Formula V:

A control valve assembly for use in a pump or injector of fuel injection systems is provided. A pump or injector body has a pumping chamber, and a valve chamber. The valve chamber defines a valve seat and has an axial guiding portion. A plunger is disposed in the pumping chamber. A valve body disposed in the valve chamber controls fuel. The valve body has a valve stem defining a seating surface. The valve body further has a valve guide in sliding engagement with the valve chamber guiding portion. The valve body is axially movable with respect to the valve chamber over a stroke range. The valve guide has an outer engagement surface that slidingly engages the valve chamber guiding portion with a clearance fit of at least about 5 micrometers in one embodiment. In another embodiment, the axial length of the engagement surface is at most about 7 millimeters. The reduced axial length and/or the clearance fit improve initial sealing performance and sealing performance over the life cycle of the product.
摘要:
Stabilizer compositions having a chroman-based compound according to Formula (V): and their use in processes for stabilizing organic materials subject to degradation and/or discoloration due to the effects from light, oxygen and heat, and in processes for producing articles from organic materials blended therewith, are provided herein.
摘要:
The present invention is directed to compounds of the formula: (wherein variables A1, A2, A3, G1, G2, G3, G4, J, Ea, Eb, Ec, R6, R7, and Y are as described herein) which are antagonists of CGRP receptors and which are useful in the treatment or prevention of diseases in which CGRP is involved, such as migraine. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which CGRP is involved.
摘要:
A mobile crushing station for receiving and comminuting excavated material from earth moving vehicles provides at least one moveable skip connected to a chassis or frame for receiving material from vehicles, such as rear unloading vehicles like dump trucks. The skips are configured to move to dump material fed into the skips into a feed hopper. The feed hopper is positioned to guide material onto a feed conveyor, such as an inclined apron conveyor. The feed conveyor is configured to transport material to a feed orifice of a crushing device, such as a sizer, a crusher, or a crushing circuit. The crushing device is configured to crush material fed into the crushing device. The crushing device also has a discharge orifice that is positioned above a portion of a discharge conveyor. The mobile crushing station is moveable so it may be repositioned closer to an excavation site as excavation activities progress.
摘要:
A method is provided of targeting short message service (SMS) message for delivery to a mobile station. When an SMS center (SMSC) in a cellular network receives an SMS message and is to send it to a mobile station, the SMS center determines the location of the mobile station either directly or indirectly via a location register. The SMS center correlates that location with a particular base transceiver station serving that location. The SMS center then causes the SMS message to be delivered to the mobile station via that particular base transceiver station. The SMS center thus can avoid sending SMS messages to all base transceiver stations in a given area, thereby conserving network resources.

The present invention is directed to compounds of the formula (I): (wherein variables A1, A2, A3, A4, A5, A6, A7, A8, G1, G2, G3, G4, J, Q, Ea, Eb, Ec, R6, R7, RPG and Y are as described herein) which are antagonists of CGRP receptors and which are useful in the treatment or prevention of diseases in which CGRP is involved, such as migraine. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which CGRP is involved.
摘要:
The present invention is directed to 3,4-substituted pyrrolidine compounds of formula (I) which are inhibitors of the beta-secretase enzyme and that are useful in the treatment of diseases in which the beta-secretase enzyme is involved, such as Alzheimer's disease. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the treatment of such diseases in which the beta-secretase enzyme is involved.
