Filed:

Dec 31, 2012

Appl. No.:

13/731296

Inventors:

Amy M. Tseng - Woodridge IL, US
Brian V. Jenkins - Warrenville IL, US
Robert Mack - Milwaukie OR, US

International Classification:

G01N 31/22

US Classification:

438 8, 436101

Abstract:

The invention is directed towards methods and compositions for identifying the amount of hydrofluoric acid in a buffered oxide etching composition. In buffered oxide etching compositions it is very difficult to measure the amount of hydrofluoric acid because it has varying equilibriums and it is toxic so it hard to handle and sample. When used to manufacture microchips however, incorrect amounts of hydrofluoric acid will ruin those chips. The invention utilizes a unique method of spectrographically measuring the hydrofluoric acid when in contact with added chromogenic agents to obtain exact measurements that are accurate, immediate, and safe.

H02G 304

US Classification:

220 6

Abstract:

An elongate container of one-piece resilient thermoplastic construction. The container includes a first wall having first and second lateral edges with a first latching component positioned adjacent the first lateral edge. A second wall has first and second lateral edges with a second latching component, for interlocking with the first latching component positioned adjacent its second lateral edge. The container also includes a hinge joining the first lateral edge of the first wall and second lateral edge of the second wall, with the hinge including a web of material having a thickness less than the thickness of the walls. The walls are relatively movable about the hinge between an as-formed position in which the first and second latching components are spaced and a use position in which the first and second walls extend relative to each other at a predetermined angle and the first and second latching components are in locking engagement. The container has a generally uniform cross section throughout its length so that it can be formed by extrusion. A method of using the container is also disclosed.

International Classification:

A61F 1316

US Classification:

128287

Abstract:

A disposable diaper comprising, an absorbent pad assembly having an absorbent pad, and a relatively thin sheet of flexible material covering a surface of the pad. The diaper has a tape fastener comprising, a pressure-sensitive tape strip having a section secured to an outer surface of the sheet in an area at least partially covering the pad. The diaper also has adhesive means directly bonding the sheet to the pad in a region extending from the area to a location spaced from the area in a direction away from forces normally applied to the strip during placement and use of the diaper.
