An armored clipboard device for inhibiting a head and a torso of an officer being impacted by bullets fired from a gun includes a case being held by the officer when the officer is writing a ticket. The case includes a front wall, a back wall and a peripheral wall extending between the front wall and the back wall. The front wall has an exterior layer and an interior layer. The exterior layer is comprised of a ballistic deflecting material to deflect rounds impacting the front wall of the case. The interior layer is comprised of a ballistic absorbing layer to slow down and stop any of the rounds that penetrate the exterior layer. A handle is coupled to the case and is grasped to facilitate manipulation of the case. An illumination assembly is coupled to the case to emit light and illuminate an area in front of the officer.

The invention relates to methods for protecting a nuclear reactor core, such as a boiling water reactor core, from fuel and cladding damage due to thermal hydraulic instability in extended operating power flow conditions and, in particular, when an extended power uprate is implemented. The methods employ existing licensed stability methodologies and incorporated minor changes, e.g., to the Average Power Range Monitor (APRM)-based trip system to preclude operation inside the stability vulnerable region of the power/flow map. The APRM-based trip system is modified to set down the APRM flow-biased scram line when core flow is less than a predetermined core flow to prevent the core from entering an unstable region of operation.

A process and system of operation for combusting nitrogen-containing fuels with resulting low NO. sub. x emissions. A fuel-rich mixture of the fuel is combusted in a catalytic bed which is carried by a support structure. Active or passive means are provided for limiting transfer of heat from the bed into the support structure for minimizing formation of NO. sub. x during combustion. The active means for limiting the heat transfer includes, in different embodiments, electrical resistance back heating, induction back heating, exhaust gas back heating, and combustion fired back heating. The passive means for limiting the heat transfer includes, in different embodiments, a body of heat insulating material between the bed and support structure, or the insulating effect of the outer cells of the bed within a recess in the support structure.

A circuit protection device for protecting batteries is formed from a resistive element composed of a PTC conductive polymer composition and two electrodes. The device has a resistive element thickness of 0. 025 to 0. 20 mm; a crosslinking level equivalent to 1 to 20 Mrads; a surface area of at most 120 mm. sup. 2 ; a resistance at 20. degree. C. , R. sub. 20, of at most 0. 030 ohm; and a resistivity at 20. degree. C. ,. rho. sub. 20, of at most 2. 0 ohm-cm. Devices of the invention are sufficiently small to be easily inserted into an assembly comprising a battery, particularly a rechargeable battery, and the device. Such assemblies are used for powering portable electronic equipment such as cellular telephones.

A conductive polymer composition which has low resistivity and good electrical stability. In one aspect the composition comprises a nonconductive filler which is a dehydrated metal oxide. In another aspect the composition comprises a conductive filler which is metal particles in which the bulk density is less than 0. 15 times the true density. Compositions of the invention are particularly useful for circuit protection devices.

A conductive polymer composition in which a particulate conductive filler is dispersed in a polymeric component which is a mixture of an essentially amorphous thermoplastic resin and a thermosetting resin. In preferred compositions, the amorphous thermoplastic resin and the thermosetting resin are substantially mutually soluble. In order to improve the thermal stability of the composition on exposure to successive thermal cycles, it is preferred that the composition be cured by heating the uncured mixture of amorphous thermoplastic resin, thermosetting resin, and particulate conductive filler at a rate of at least 15. degree. C. /minute to the cure temperature.

A composition which contains 35 to 85% by weight of a copolymer of tetrafluoroethylene and hexafluoropropylene (FEP), 10 to 60% by weight of a copolymer of tetrafluoroethylene and perfluoropropylvinyl ether (PFA), and 5 to 60% by weight of melt-processable polytetrafluoroethylene (PTFE). The composition is particularly suitable for use as an insulating material on a substrate such as a resistive element in a conductive polymer heating cable. The composition has good physical properties, low creep, and low secondary crystallization, and exhibits little stress-cracking when exposed to elevated temperatures.
