Improvements relating to the armouring or protection of structures subject to the attack of projectiles

... 150,831. Eyncourt, Sir E. H. T. d', and Williamson, L. C. June 13, 1919. Armour.-Structures are protected against attack from armour-piercing and other projectiles by the provision of a number of bars or girders A spaced at such a distance apart that the point of an attacking projectile cannot impinge on the surface of the structure. The bars are of hardened or toughened steel or steel alloy, and of substantial cross-section. In a modification, the bars are made of such cross-section that they interlock, as shown in Fig. 4, the bars being such that the point of the projectile cannot impinge directly on the under bars. A covering armour-plate may be fitted over the upper surface of the bars, and may be at such a distance thai the point of any shell strikes the bars before the base of the shell has passed through the armour plate. Specification 4761/76 is referred to.

Plate for body armour is surface textured by patterns of dimples for weight reduction

A plate for incorporating in body armour is made from an impact absorbing material and is improved by having a raster pattern of recesses or dimples on at least one side. For a dual sided pattern the two raster arrays are offset to prevent undue thinning of the material. The recesses can have the same depth and with a different density towards the edges of the plate. A partial filling with a ballast material, eg. resin, enables the designer to vary the impact absorbing properties across the plate. The edges of the pattern can be rounded near to the edge of the plate to reduce the risk of stress.

Ultra Light Bar Armor

Bar armor currently provides a means of providing partial protection of vehicles and structures against certain types of Rocket Propelled Grenades (RPGs). However, the individual bars must provide enough strength to cut through or deform the outer ogive of an RPG and cause electrical contact with the inner ogive. This in turn imposes constraints on the overall effectiveness of the system and how light it can be made. These constraints can be eased by providing cross-attachments for the bars, provided that the cross-attachments themselves are of low enough density and sufficient frangibility to avoid detonating the RPG when they are struck by the RPG nosepiece, which contains a piezoelectric element that causes the fuse of the RPG to function. Through this means, bar armor can be made lighter, more effective, and easier to see through. 1. An armor system for protecting against an incoming RPG or similarly fused threat , comprising a plurality of parallel bar members and a plurality of cross-attachment members , wherein said bar members are separated from each other by a spacing , wherein said cross-attachment members are connected to the bars to permit penetration of a portion of the RPG through said bar members without setting off the explosive charge if the RPG strikes the cross-attachment member , and wherein said cross-attachment member is connected to said bars to restrict expansion of said spacing by the ogive of the incoming RPG if the RPG nosepiece does not strike the bar , such that contact of the RPG ogive with the bars causes shorting of the RPG fuse circuit.2.

(canceled) This international patent application claims the benefit of U.S. Provisional Application No. 62/155,737, filed May 1, 2015, and U.S. Provisional Application No. 62/293,456, filed Feb. 10, 2016, the entireties of which are incorporated herein by reference.The present invention relates generally to devices and methods for securing distressed individuals and more particularly, but not exclusively, to an emergency rescue stretcher for removing a victim from a confined space.Stretchers are often used by emergency personnel to transport injured persons and victims from accident sites to an emergency transport vehicle or a hospital. Such stretchers are also designed in certain circumstances to secure the victim and prevent further injury.People may become trapped or injured in a confined space or location, such as a basement or shaft. In such instances, ordinary stretchers may not fit within the confined space. For example, when fighting a fire, a fireman may be injured and trapped in a basement. Without the ability to secure the injured fireman on a stretcher, rescuers will tend to pull the fireman out by his or her equipment or clothing. This process often results in the removal of the fireman's equipment before extraction of the fireman from the basement as the equipment is prone to being pulled off during extraction. Moreover, rescuers may exacerbate a trapped fireman's injuries when attempting a rescue without securing the fireman's body before extraction.Therefore, a present need exists ...
