Record 7 2009-06-03

English

Subject field(s)
  • Building Elements
  • Air Transport
CONT

An anti-bird roosting device for protecting an area, comprising at least a pair of cooperating base elements mounted on the area to be protected, and a plurality of projecting spikes, supported on the base elements and projecting away therefrom into a space above the area to be protected. The spikes are provided in a pattern of interspersed combinations of vertical, obtuse and acute angle-forming projections, in a high spike density that prevents roosting in the protected space. Thus, each point in the area to be protected is defended by more than one spike, each spike coming from a different direction, so as to cross-defend each other, creating a perimeter envelope defense of the air volume surrounding the base elements. Each device is easily and inexpensively prepared as a continuous mesh, whose dimensions can be constructed in standard sizes or in accordance with the needs of the user. The element diameter is typically approximately two millimeters. The small element diameter makes the entire device hard to see from a distance so that it does not detract from the building's aesthetics.

CONT

Porcupine wire, typically marketed as Nixalite, prevents birds from perching and roosting on flat surfaces such as ledges and signs. ... Nixalite is a system of stainless steel strips that feature needle-like wire prongs. The prongs project from a 0.5 centimetre base and come in two lengths - 5 and 9.5 centimetres. Strips are available in either single (90°) or double (180°) radius.

Les bandes hérisson, habituellement vendues sous le nom de Nixalite, empêchent les oiseaux de se percher et d'aller dormir sur des surfaces plates comme les rebords des bâtiments et le dessus des panneaux. [...] Le Nixalite consiste en bandes d'acier inoxydable hérissées de piquants qui ressemblent à des aiguilles. Les piquants, qui font 0,5 centimètre à la base, sont fabriqués en deux longueurs : 5 et 9,5 centimètres. Les bandes sont offertes à rayon simple (90°) ou double (180°).

CONT

After launch, and as the ASCM [anti-ship cruise missile] nears the target, distraction cartridges are fired at ranges up to 4. 5 km to disturb the range and accuracy of the missile's guidance system. However, should the missile have already locked on to the ship in its final attack phase, seduction chaff is deployed to provide point defense and a means sometimes in coordination with other on-board EW [electronic warfare] equipment, to "pull" the seaker away from the ship to the chaff cloud.

DEF

The point on the slope of a hill that will not allow any person or object to be silhouetted against the horizon and also allows full view of the slope below.

CONT

The military crest... is the point near the top of a slope or brow from which the entire slope below can be seen. This strategic vantage point has historically been vital for an army's control and defense of the high point and surrounding countryside(hence its name). The military crest is also a desirable building location because of the view it affords.... Furthermore, the military crest is an important point for locating structures that visually blend in with the landform.

CONT

The top of the slope is most exposed to the elements. The planner may exploit or create a land profile similar to the "military crest" of the artillery manual--an adaptation or modification of the slope to preserve or enhance the view while affording increased protection.
