Abstract:
The present invention provides an automatic sampling and dilution apparatus for use in a polymer analysis system. The apparatus comprises (a) a primary mixing chamber; (b) a primary pump capable of continuously withdrawing a variable viscosity liquid from a reactor at a selectable, fixed withdrawal rate over a varying viscosity range of about 50 to about 5,000,000 centipoise (cP) for continuously conveying the variable viscosity polymer-containing liquid into the primary mixing chamber; (c) a first dilution pump for continuously delivering a first dilution solvent into the primary mixing chamber at a selectable, fixed flow rate to mix with the variable viscosity liquid in the mixing chamber and thereby form a diluted polymer-containing liquid therein; and (d) a secondary pump for continuously conveying the diluted polymer-containing liquid into a flow-through detector. A polymer analysis system utilizing the automatic sampling and dilution apparatus is also provided.
Abstract:
A vehicle includes a vehicle body, a tailgate and a hinge assembly. The tailgate is rotatable relative to the vehicle body between a closed position and an open position. The hinge assembly rotatably coupling the tailgate to the vehicle body. The hinge assembly includes a bracket, a hinge pin and a retention ring. The bracket is attached to a respective one of a plurality of side walls of the vehicle body. The hinge pin is rotatably fixed to a respective end of the tailgate and is removably connected to the bracket. The retention ring is rotatably coupled to the bracket between a locked state in which the hinge pin is prevented from being disconnected from the bracket and an unlocked state in which the hinge pin is permitted to be disconnected from the bracket.
Abstract:
A secure card such as a credit card having a magnetic strip thereon is disclosed. The magnetic strip is coated with a thin amorphous layer having electrical characteristics and a processor. In a first state, the amorphous layer acts to interfere with reading of information from the magnetic strip. Identification of a user of the card as an authorized user thereof results in a second state in which the information stored in the magnetic strip is accessible. For example, biometric identification or the use of a PIN entered either directly into the card or through an input terminal cause the processor to switch power from the amorphous strip thereby removing the interference and unmasking the information on the magnetic strip.
