Abstract: A diamond reference standard contains a diamond composite of 60-90% diamond crystals and 10-40% silicon carbide binding agent doped with a plurality of elements. The standard is prepared by doping a diamond composite containing a silicon carbide binder with a plurality of elements, the presence of which can readily be detected using a variety of instruments, e.g. a mass spectrometer.

Abstract: The invention relates to a delivery device designed to carry Mineral Water Bottle (MWB) counter charges, by remote means, to a target Improvised Explosive Device (IED) during render-safe procedures. The delivery device is die-cut as a blank and folded into the desired form. The device includes at least one elongated tubular holding element for receiving a MWB counter charge with a lifting strap attached thereto that can easily be grasped by any remote means. The device is designed in such a way so as to provide automatic positioning of the MWB counter charges at the appropriate stand-off distance in relation to the IED. As well, the delivery device is fully collapsible so as to facilitate the storage and transportation of the device, and provides a quick and user-friendly system that facilitates the deployment of MWB counter charges.

Abstract: A release mechanism for use with an explosives disposal robot having an elongated boom includes a latch member secured to an outer end of the boom, the latch member having a fixed portion and movable latch or lever members. A flexible strap extends between the lever members, with one end being attached to one of the lever members and the other end being releasably attached to the other lever member. When the other lever member is moved to a release position the other end of the strap falls from the other lever member so as to release, for example, a firing line cradled in the strap. The one lever member can be actuated by way of a remote controlled solenoid connected thereto via a flexible cable or by way of an elastic member connected thereto.

Abstract: The invention provides a “change of direction” device for use by a law enforcement technician. The device can be readily and easily attached to a building element and will allow the technician to pass a rope, wire or cable therethrough so that the rope, wire or cable can be pulled by the technician after one end has been attached to a hazardous item of concern. The change of direction device (CODD) would be positioned within the building at strategic locations where it is clear that the item of concern will have to change directions as it is being pulled from the location at which it was found. The invention provides several embodiments of the CODD for attachment to a wall, to a door hinge, or under the bottom edge of a door. Each CODD is simple in construction and is of such a nature that it can be positioned at the desired location without any preparation having to be done.

Abstract: A remotely operable opening mechanism for potentially booby-trapped latched panels has a clamp member for clampable engagement with a fixed structure on the panel. A displaceable actuator is mounted on the clamp member. The displaceable actuator has a protruding element engageable with a latch on the latched panel and a coupling element for connection to a line to permit remote activation of the actuator to release the latch member and thereby permit the latched panel to be opened from a safe distance.

Abstract: A hair root collection kit for delivering hair samples to a laboratory for DNA analysis of the root sheaths includes a card with an adhesive strip extending thereacross for holding the hair samples on the card. With the hair samples on the card, the root sheaths overlie a non-adhesive impermeable plastic area. The card is covered by a clear plastic cover for protecting the hair during delivery to the laboratory.

Abstract: The invention disclosed relates to a foam-forming composition, for suppression/containment of blast from explosive devices. The composition comprises, a) a surfactant 40-80% w/w b) a foam stabilizer 0-7% w/w c) a polyalkylene glycol 10-30% w/w d) water, balance to 100%.

Abstract: The invention disclosed is an apparatus for explosive blast suppression, and a method therefor, the apparatus comprising a hemispherical enclosure (10) defined by an upstanding wall, positioning means (42) associated with the enclosure, for positioning the explosive device substantially equidistant from any point on the wall, and in a preferred embodiment includes an integral floor (40) and a rounded lower wall, to provide a substantially even distribution of blast forces in all directions toward the wall. The enclosure is made of composite textile material, comprising one or several layers of a ballistic material (e.g. Dyneema Kevlar) sandwiched between inner and outer layers of a light-weight rip-stop nylon fabric material.

Abstract: A method and foam formulation are provided for enabling both blast suppressing and decontamination, particularly desirable when faced with an explosive device which has been rigged with a contaminant for destructive dissemination. A formulation is foamed to surround the explosive CB contaminant device, preferably encapsulated in a containment structure. The preferred composition of foamer-compatible decontaminant and foamer to foam and surround the device is about 1% to 3%/w of hydrated chloroisocyanuric acid salts and more including lithium hypochlorite, about 1% of a co-solvent selected from the group consisting of polypropylene glycols, polyethylene glycols, and derivatives and mixtures thereof; about 1% to about 5% of a surfactant and foam stabilizer; and a buffer system to initially maintain said formulation at a pH from about 11.0 to about 8.5 for a minimum of 30 minutes; and the balance being water.

Abstract: The invention disclosed relates to a composite armor material comprising an outer ballistic impact resistant layer of a steel material having a Rockwell “C” scale hardness of 47-54, and an inner blast resistant steel layer having a fracture toughness of 3.6-6.5 J/mm, and a Rockwell “C” scale hardness of 28-36.

Abstract: A welded joint suitable for connecting armor plates in armored vehicles obtained by providing one of the armor plates, or an interconnecting element, with a semi-circular rounded lobe; and welding the lobe to the plate to be joined to form a U-shaped welded region such that the ends thereof are directed to the outside edge of the plate so that a crack formed in the weld will tend to propagate along the weld to the outside of the plate. The joint can be used for lap joints, angled joints, and joints involving multi-layers of plates. The joints facilitate utilizing the armor plates to provide a unitary mechanical structure for the vehicle.

Abstract: A foam generating nozzle is disclosed comprising a cylindrical housing, a first inlet at one end of the housing for connection to a supply of foamable liquid under pressure, a second inlet at the first end for air supply, a foam discharge outlet at the other end of the housing, a diffuser associated with the first inlet and a conical screen of a non-corrosive material disposed in said housing between the ends with its apex directed toward the discharge outlet, to provide a screen surface area larger than the inlet air supply area, such that in operation the foamable liquid is sprayed onto the screen by the diffuser in a pattern which matches the conical shape of the screen, while air is dragged through the screen thereby generating the foam.
