Appl. No.:

08/873972

Inventors:

Alfred D. Commins - Danville CA
Robert C. Gregg - Yorba Linda CA

Assignee:

Simpson Strong-Tie Company, Inc. - Dublin CA

International Classification:

E04B 228

US Classification:

524831, 523092, 5280012, 5280018

Abstract:

The present invention relates to horizontal, vertical or angularly disposed diaphragms which resist structural forces. Specifically, the present invention relates to an improved mechanical connection between a structural panel and the framing members that support the structural panel forming a diaphragm. The connection includes: a structural panel having a distal side, a proximal side, and a plurality of edge faces; a frame consisting of a plurality of framing members disposed in registration with the proximal side of the structural panel near the edge faces; a plurality of perimeter fasteners connecting the structural panel to the framing members; and clips or perimeter edging members for reducing bending of the perimeter fasteners attached to a substantial number of the perimeter fasteners. The clips or perimeter edging members for reducing bending of the perimeter fasteners act when lateral forces are imposed on the building structure of which the diaphragm is a part.

Abstract:

A laser pulse driving method comprises the steps of selecting a desired laser pulse energy level and a laser pulse width, and then determining a target flashlamp current level corresponding to the laser pulse energy level and the laser pulse width. Further, the method teaches generating a reference voltage corresponding to the target flashlamp current level at a first input of a comparator, closing a power switch to deliver an actual flashlamp current level to the flashlamp from a pulse capacitor, and then presenting a shunt voltage proportional to the actual flashlamp current level at a second input of the comparator. Further steps include, turning-on a comparator output when the shunt voltage is less than the reference voltage, receiving the comparator output at a first AND gate input, receiving a control signal at a second AND gate input for a time equal to the laser pulse width and then applying the AND gate output at a power switch driver when both the first and the second AND gate inputs are present. A power switch delivers the actual flashlamp current level from the pulse capacitor when the AND gate output is present whereby the laser pulse energy level is applied to the flashlamp in a laser pulse having the desired laser pulse energy level and laser pulse width.

International Classification:

B64C013/16

US Classification:

244203000

Abstract:

A mobile platform lift increasing system includes at least one wing-shaped structure having a leading edge, a trailing edge and a chord length perpendicularly measurable between the leading and trailing edges. A rotatable control surface is located near a trailing edge undersurface. The control surface length is approximately one to five percent of the chord length. A deployment device is positioned between the wing shaped structure and the control surface. The deployment device operably rotates the control surface through a plurality of positions ranging between an initial position and a fully deployed position. Wing lift is increased at speeds up to approximately transonic speed by continuously rotating the control surface to accommodate variables including mobile platform weight change from fuel usage.

International Classification:

B64C003/00

US Classification:

24403500R

Abstract:

A wing having a transition region forming a blended, aerodynamic transition between inner and outer regions of the wing. The blended transition region does not include any planform breaks at the leading and trailing edges, where conventional wings would have such planform breaks. This allows the wing to be manufactured without significant forming and/or shot-peening operations to conform the skin of the wing to the planform breaks. Thus, the wing of the present invention can be manufactured with less cost and in less time, and provide even better aerodynamics than conventional aircraft wings. The wing of the present invention is further suitable for use on aircraft or aerospace vehicles, or any airborne vehicle requiring one or more aerodynamic airfoils or wing-like structures.

Abstract:

A method for removing deep gingival pockets provides for excise of disease while providing for reconnection of the tissue-tooth connection. Steps in the process include creating a gingival trough in the pocket with a contact laser fiber, excising the pocket epithelium while selectively removing sulcular and pocket epithelium and granulation tissue fully around the targeted tooth to the full depth without breaking through the mucogingival junction, scaling the root surfaces to the full depth ultrasonically, lasing the pocket to remove granulation tissue and to disinfect the tissue, assist in hemostatis, cauterize free nerve endings, seal lymphatics, prepare the tissue for welding and desensitize the tooth, and compressing the tissue against the tooth until adhesion is achieved.

244 35R

Abstract:

A special contour near the trailing edge of an airfoil which improves the airfoil effectiveness. The contour is a combination of a blunt airfoil base, a local region of high surface curvature, typically on the airfoil lower surface, and upper surface and lower surface trailing edge slopes that diverge from each other.
