Abstract: An armor panel adapted to protect a body from an incoming projectile, the armor panel comprising an armor member constituted by at least one layer. The layer is encapsulated within and pressed upon by a wrapping as a result of an arresting process. The panel has a front, rear and side walls. The wrapping is preformed, prior to the process, with at least one outlet hole at least one of the rear and side walls. Through the outlet hole, air trapped within the armor panel prior to the arresting process, and/or excess gasses produced during the process, are allowed to escape.

Abstract: A dual hardness armor, comprising a first steel layer of hardness H1 and thickness D1, a second steel layer of hardness H2 lower than H1, and a thickness D2 not greater than D1. The armor further comprises an intermediate substance therebetween bonding the first steel layer to the second steel layer.

Abstract: An energy absorbing device for reducing acceleration transmitted to a seated occupant in a vehicle as a result of a high energy impact. The device comprises a first energy absorbing mechanism having a first dimension in the impact direction and capable of undergoing predetermined elastic deformation in that direction; and a second energy absorbing mechanism having a second dimension in the impact direction, which is smaller than the first dimension by a distance corresponding to that elastic deformation. The second mechanism is loaded with the impact force after the first mechanism has undergone elastic deformation; the second mechanism comprises a material capable of progressive deformation. The device may comprise a restriction mechanism connecting the two plates, adapted to restrict displacement of the first plate relative to the second plate in any direction different from the impact direction.

Abstract: An energy absorbing device is provided for reducing acceleration resulting from a force of a high energy impact acting on one side of the device in an impact direction. The device includes two plates transverse to the impact direction, an energy absorbing mechanism between the plates, and a stabilizing mechanism having at least one pair of a projecting element and a receiving element, the projecting element comprised on one plate and a corresponding receiving element comprised on the other plate. Each pair is adapted for enabling the projecting element thereof to be at least partially received by the corresponding the receiving element in a manner to restrict relative displacement between the two plates at least in one direction different from the impact direction and to allow substantially free relative displacement between the plates in the impact direction.

Abstract: A composite armor plate with a layer of pellets in a binder matrix, the pellets having domed front and planar back end and a reduced weight. A method of producing the plate comprises providing front and back layers, applying binder material to the pellets and the layers, and heating the binder material to form the matrix and bind the front and back layers thereto. Each pellet may be coated with a primer adapted to facilitate the binding.

Abstract: An armor designed for ballistic protection against armor piercing projectiles, comprises a main armor plate including a layer which is at least partially made of a ballistic material, e.g. in the form of a plurality of bodies, and an auxiliary armor plate at least partially made of a ballistic material. The auxiliary plate is located in front of the main armor plate and is spaced therefrom by an area, which is at least partially free of any additional layers. The auxiliary plate has through holes spaced from each other, which are free of any ballistic material.

Abstract: A composite armor structure for ballistically protecting a gap from an impacting projectile threat and for use with at least one ballistic armor module. The gap extends along a margin of the module. The structure comprises a body having a protection portion with at least a single layer of ceramic bodies. The structure further comprises a carrier portion supporting the protection portion and being made of a material different from the ceramic bodies. The protection portion is designed to span the gap. The carrier portion is designed to extend beyond the gap to overlap with the margin when viewed from a perspective of the impacting projectile threat.

Abstract: Ballistic armor for providing ballistic protection from an impacting projectile threat. The armor comprises a plurality of composite armor units. Each unit comprises a ceramic body having a cylindrical body portion with two end faces, one of which is adapted to face said threat. Each unit further comprises a non-ceramic belt member assembled with the ceramic body so that said member contiguously surrounds the cylindrical body portion without covering the one end face.

Abstract: The invention provides an armor system for ballistic protection of a flexible conduit, the system comprising a plurality of protective tubular elements in axial alternating array with double-socket joint elements, the outer peripheral ends of the tubular elements being provided with a convex curvature complementary to a concave curvature provided along the inner peripheral ends of the double-socket joint elements, a protective tubular element being inserted in each end of the double-socket joint elements, the curved peripheral end allowing any tubular element connected to a double-socket element to till freely relative thereto.

Abstract: Devices and compositions are provided for cleaning optical surfaces with carbon black. Carbon black may be impregnated on a soft pad, such as chamois leather, to provide a lens cleaning device. The soft pad may be supported on a handle. The soft pad may be mounted on the handle by a resilient member that is capable of adapting with the soft pad to conform the cleaning surface to concave or convex optical surfaces. A retractable brush may be mounted at the opposite end of the handle from the soft pad.
