Waters Technologies Corporation - Milford MA

International Classification:

B01D 15/08

US Classification:

210635, 210656, 2101962

Abstract:

A liquid chromatography system comprising a chiral mobile phase used to separate enantiomeric molecules present in a sample is disclosed herein. In one aspect, the mobile phase comprises a chiral solvent. In another aspect, the mobile phase includes a chiral solvent but also a buffering agent. The liquid chromatography system described herein includes both high pressure liquid chromatography (HPLC) as well as high pressure capillary liquid chromatography (CapLC).

US Patent:

52115879, May 18, 1993

Filed:

Aug 20, 1992

Appl. No.:

7/933496

Inventors:

Peter H. Alden - North Easton MA

Assignee:

Alden Proucts Company - Brockton MA

International Classification:

H01R 1300

US Classification:

439843

Abstract:

A socket for a high voltage plug is folded from a single sheet of metal to form a cylindrical corona shield on an axis about a pair of spring contacts. The shield and contacts extend from a cylindrical base of the shield along a solder face to an outer segmental lip for suppressing corona from wiring on the face.

US Patent:

60103485, Jan 4, 2000

Filed:

May 19, 1998

Appl. No.:

9/081270

Inventors:

Peter H. Alden - Easton MA

Assignee:

Alden Products Company - Brockton MA

International Classification:

H01R 1352

US Classification:

439274

Abstract:

A resilient tapered conical insert (40,70) is snap fit into a mating recess in each side of a two-piece multi-circuit connector (50, 80). A coupling body segmented latch arm (501, 801) expands over an insert ramp (410, 701) with segmented tabs (42, 82) and locks into an insert recess groove (402, 702) for a tactile and audible signal of engagement and a secure permanent union. Replaceable contact elements (20, 90) are snap fit in a fluid-resistant self-sealing relationship to selected mating openings (44, 74) in the inserts with a contact protrusion (22, 92) engaging an insert shoulder (140, 170) and contact barbs (23, 93) engaging resilient insert openings (145A, 171). A front contact barb (24, 94) snaps into a larger insert opening (45, 74) for a tactile and audible feedback of complete insertion. Replaceable inserts may be fitted with any desired configuration of paired contact elements assembled in the field. Blank or partially blank inserts (40B, 70B) may be drilled in the field.
