Assignee:

Blistex Inc. - Oak Brook IL

International Classification:

A45D 3300
A61M 3500

US Classification:

401130

Abstract:

A pad and container assembly wherein the pad comprises a sponge-like center section and a non-permeable protective disk secured to its inner side, which is immersed in a medicament in the bottom of the cup, the disk being pressed against an annular ridge containing the medicament and conforming to its shape to form a seal, the center section of the pad being compressable within the container, the pad having a foldable handle on its upper side which is extendable when the container is opened upon removal of a cover releasably adhered to the outer rim of the container.

Appl. No.:

8/561443

Inventors:

Michael A. Wojcik - Naperville IL
Michael J. Donnantuono - Naperville IL

Assignee:

Blistex Inc. - Oak Brook IL

International Classification:

B65D 4116

US Classification:

220339

Abstract:

A closure for a container is provided which includes a collar engaging the opening of the container, and a removable cap pivotally hinged to the collar by means of a double-fold hinge. When closed, the cap fits over the collar. The arc of travel of the cap as it pivots between its opened and closed position is such that the cap clears the cap engaging portion of the collar and the product in the container. The upper surface of the cap includes a chordal ridge which is adapted to be engaged by thumb pressure enabling easy grasping and opening of the container using one hand. The collar includes a cap engaging portion having at least one upstanding bead circumferentially disposed along an outside surface while the cap has at least one ridge circumferentially disposed along an inside surface configured to engage the upstanding bead when the cap is removably placed over the cap engaging portion such that the cap is retained on the collar.

International Classification:

H03M 700

US Classification:

341 58

Abstract:

A method and apparatus for encoding and decoding m-bit groups of digital data, where m is at least eight, into serial n bit groups such that each encoded serial n-bit group has sufficient data transitions therein to maintain the synchronization of a phase locked loop clock recovery circuit in a high speed serial link of a communication path. Further, this method and apparatus provides a duty cycle that is within an operational range of the ideal 50 percent, which reduces voltage drift of a. c. coupled high speed serial data links, or reduces thermal drift of optically coupled high speed serial data links.

International Classification:

A61B 6/00
G01T 1/29

Abstract:

Phase contrast and dark-field X-ray imaging enable imaging of objects that absorb or reflect very little X-ray light. Disclosed is a method and systems for performing coded-mask-based multi-contrast imaging (CMMI). The method includes providing radiation to a coded mask that has a known phase and absorption profile according to a pre-determined pattern. The radiation is then impingent upon a sample, and the radiation is detected to perform phase-reconstruction and image processing. The method and associated systems allow for the use of maximum-likelihood and machine learning methods for reconstruction images of the sample from the detected radiation.
