A process of calendering a sheet or a film having at least one textured surface entailing passing a web (4) of polymeric resin through a nip between a rigid roll (2) and a resilient roll (3) is disclosed. The inventive process comprises slowing down the cooling rate of the web by rolling its textured surface about the resilient roll. The rate of cooling is in comparison to a corresponding process where the web is rolled about said rigid roll. Products thus produced are suitable for making thermoformed articles having low gloss.

A pressure ring for a lancing device for holding open a skin puncture while collecting a blood sample includes a collar that fits onto the end of a lancing device. A skirt is provided on the collar and a flared portion depends from the skirt. At least one axial slit is formed in the skirt. The pressure ring is made of a flexible material such as polypropylene such that when the lancing device with a pressure ring is placed on a person's skin and pressure is applied, the slits spread apart stretching the skin for a puncture by a lance in the lancing device. Once a puncture has been made, the pressure ring holds the puncture wound open to allow bleeding. Removing the lancing device from the puncture site releases the skin allowing the puncture would to close.

The present invention provides a fibrinolytic composition useful as a therapeutic for administration to a patient having a thrombotic occlusion. In one aspect of the present invention, the fibrinolytic composition comprises a reversibly inactivated acidified serine protease substantially free of a plasminogen activator, a low buffering capacity buffer, and optionally, a stabilizing agent. In another aspect of the invention, the fibrinolytic composition of the present invention comprises a reversibly inactivated acidified plasmin substantially free of a plasminogen activator, a low buffering capacity buffer, and optionally, a stabilizing agent.

This invention relates to a process for preparing perylene pigment compositions by
(a) reacting, at a temperature of less than about 25°C, a mixture of
(1) a perylene tetracarboxylic compound, (2) at least about 0.1% by weight, relative to the perylene tetracarboxylic compound, of a surfactant of formula (I) wherein R 1 , R 2 , R 3 , X, Y, Z, and Z' are defined herein, (3) an equivalent excess, relative to the amount of the perylene tetracarboxylic compound, of ammonia or a primary amine R A -NH 2 , wherein R A is defined herein, and (4) optionally, a solvent, to form a perylene intermediate; (b) heating the perylene intermediate at a temperature of about 50°C to about 250°C, optionally in the presence of certain non-pigmentary cyclic anhydrides or imides and/or solvents; and (c) collecting the perylene pigment composition.
摘要:
A method and apparatus are provided for data management authentication in a clinical analyzer. The clinical analyzer includes a sensor for receiving a user sample to be measured and a processor for performing a predefined test sequence for measuring a predefined parameter value. A memory is coupled to the processor for storing predefined parameter data values. An authentication password is associated with each data transmission by the clinical analyzer and read by an associated computer system to validate each data transmission. The authentication password is generated by the clinical analyzer utilizing predetermined information in each data transfer.
