Filed:

Jan 13, 1993

Appl. No.:

8/004751

Inventors:

Paul V. Dunlap - Woods Hole MA
Sean M. Callahan - Woods Hole MA

Assignee:

Woods Hole Oceanographic Institution - Woods Hole MA

International Classification:

C12N 1531
C12N 1553
C12N 1570

US Classification:

435 691

Abstract:

Novel substantially pure periplasmic 3':5'-cyclic nucleotide phosphodiesterases are provided which are obtainable from gram negative bacterium capable of growing on restricted media containing cAMP or cGMP as a sole carbon source. Also provided is the isolated DNA coding for such enzymes and related methods of producing the same.

International Classification:

G09F 9/302
G09F 7/18
G09F 7/14

US Classification:

4060601

Abstract:

A support component comprises a tab configured to be coupled to a bar (as comprises a part of an item to be suspended), the tab including a plurality of openings disposed therethrough and configured to receive an overhead support interface (such as a corresponding flexible link) to thereby provide overhead support to the bar. These openings can be laterally offset from one another to facilitate selecting a particular pitch orientation for the bar. The tab can have a non-circular hole disposed therethrough sized and configured to receive the bar. This hole can include a surface that is configured to key with respect to a corresponding bar surface to thereby prevent the bar from rotating.

International Classification:

G09F 13/04

US Classification:

40541

Abstract:

A physically-discrete sign component comprises an internally-electrically-illuminated alphabetic character having a front-facing profile and at least one connecting bar disposed at least substantially horizontally with respect to the front-facing profile of the alphabetic character and at least partially within the front-facing profile of that alphabetic character. By one approach the physically-discrete sign component includes two of the connecting bars. If desired, these two connecting bars are disposed at least substantially parallel to one another. By one approach, a first one of the connecting bars extends partially, but not wholly, above an upper periphery of the aforementioned front-facing profile while the second connecting bar extends partially, but not wholly, below a lower periphery of the front-facing profile. The connecting bars can include a connecting-bar interface configured to physically and electrically interconnect to an adjacent sign component.
