US Patent:

60189819, Feb 1, 2000

Filed:

Jun 15, 1998

Appl. No.:

9/098023

Inventors:

Craig A. Higgins - San Diego CA
Robert C. Higgins - San Diego CA
Stanley S. Kuerbis - San Diego CA

Assignee:

Sinak Corporation - San Diego CA

International Classification:

G01N 122

US Classification:

73 1901

Abstract:

A test kit for measuring vapor emission from a concrete floor or other planar surface prior to installing a flooring material includes a relatively rigid dome-shaped cover having an outer bottom rim for seating with the planar surface to be tested when the cover is placed on the surface over an uncovered container of moisture absorptive material such as calcium chloride. The test kit further includes a weight ring that is removably placed onto a shoulder portion of the cover located at the cover's outer bottom rim. Placement of the weight ring on the dome-shaped cover during tests acts to hold the outer bottom rim of the cover in seating contact with the test surface. The test kit is easy to use and provides for reusable components. It can also be used without leaving a residue on the test surface.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G03G 1504
B41B 2108
B41B 1300
G02B 2730

US Classification:

355 3R

Abstract:

An optical system for use with laser chips to counteract variations in wavelength produced by semiconductor chips, to counteract astigmatism effects common to laser chips, to counteract variations in the distance between the plane of emission of the beam and the plane of a collimating lens, to counteract variations in beam size in perpendicular planes, to counteract variations in the divergence angle of emission common to laser chips, and to counteract tilt variations caused by imperfect reflecting surfaces. The system includes an apertured achromatic doublet lens for collimating the beam, a cylindrical lens, a rotating mirror, and a combination of toroidal and spherical lens.
