Abstract: A restraining device for use in securing a prisoner having an upper control strap gripped through a releasable cam buckle and secured to a pair of handcuffs worn by an individual behind his back, the loose end acting as a hand grip. The cam buckle is attached to leg shackles worn on the ankles of the prisoner be means of a lower strap loop of fixed length The length of the upper control strap between the handcuffs and the cam buckle can be adjusted by pulling the control strap through the cam buckle, thus tightening the restraining device relative to the prisoner's wrists and ankles. The overall length can be increased by opening the cam buckle and sliding the buckle along the control strap as desired. A strap lock is located on the loose end of the control strap to be slid to a position against the cam buckle to assure a secure closure thereof.

Abstract: A gasification system for solid wastes having a thermal reactor and a mechanical gas cleaner, an indirect heat exchange cooler, and an electrostatic precipitator for cleaning and cooling the produced gas. Feed material is continuously fed to the central section of the thermal reactor above an air introduction manifold and nozzles and in an upward direction, forming a stratified charge. As feed material moves upward and outward from the reactor center it is reduced to ash. An agitator assures contact between the hot particulate product and hot gases resulting in gasification of the feed material and net movement to the sidewall of the thermal reactor, forming ash. The air introduction nozzles serve as a grate. Ash descends along the sidewall to the reactor base for removal. The mechanical cleaner has a high speed rotating brush-like gas separator element and scraper combination which removes condensed tars and particulates from the produced gas stream.

Abstract: A multidimensional gas chromatograph (GC) system having wide bore capillary and narrow bore capillary GC columns in series and having a novel system interface. Heart cuts from a high flow rate sample, separated by a wide bore GC column, are collected and directed to a narrow bore GC column with carrier gas injected at a lower flow compatible with a mass spectrometer. A bimodal six-way valve is connected with the wide bore GC column outlet and a bimodal four-way valve is connected with the narrow bore GC column inlet. A trapping and retaining circuit with a cold trap is connected with the six-way valve and a transfer circuit interconnects the two valves.

Abstract: A folding tactical bridge module and bridging system and method of deploy and retrieval. Each module is made up of three longitudinally collapsible units interconnected and folded in a side-by-side arrangement to be carried by a bridge transporter vehicle. Each unit includes an arched roadway portion made up of two arcuate segments with a hinge at the centerline and a truss hingedly connected at each longitudinal edge. Tensile links tie the edges of the arched roadway together. The module folds in two ways with the tie links nested between the vertically collapsed first folded roadway segments which in turn are nested between a pair of vertical trusses. The three units of each module are in turn folded a second time into a side-by-side compact relation upon a transporter deploying vehicle. The bridge may be expanded and emplaced by the bridge transporter vehicle and its two-man crew using self-contained extendable-retractable interconnectable traversing beams associated with each of its three units.

Abstract: Apparatus and a method for determining the tire pressures of vehicles as y pass an instrumented checkpoint on a roadway. Rigid corrugations on the roadway set the tires into vibration with a waveform which is a function of tire pressure. The complex waveforms from each tire of a given vehicle are subjected to a spectral analysis and the results of such analyses are compared to each other to determine which, if any, of said tires have produced a spectrum different from the normal spectra produced by the other tires. This invention requires no apparatus mounted on the vehicles being checked.

Abstract: A radar attenuating composition is described for which incident microwave diation is absorbed and/or scattered, causing a significant decrease in retroreflectance of the object to which the composition is applied, that is, a reduction in the radar cross-section of the object. The radar attenuating composition or paint is prepared by uniformly mixing thin conducting fibers such as stainless steel fibers or carbon or graphite into a standard camouflage-type paint. The fibers act as electric dipole segments. The purpose of the countermeasure paint of the present invention is to reduce the amount of microwave radiation reflected back by a target to the receiver, i.e. reducing the amount of retroreflection.

Abstract: A method of cleaning and replacing fluids of hydraulic brake systems is pided. The method may be implemented to either clean the system and resupply the same type of fluid or replace one type of brake fluid with a new and different type of brake fluid. The method includes the use of an intermediate solvent fluid, generally in combination with air, to dilute the first contaminated brake fluid which, in turn, is displaced by the introduction of the new brake fluid, whether it be of the same or different type. The purpose of the intermediate fluid is to flush the contaminated fluid from the system as well as to alter the properties of the contaminated fluid. The use of the intermediate solvent induces a reversal of the phases of the two respective brake fluids by modifying the density of the fluid with which it is mixed.

Abstract: A multiple component catalyst system for curing of energetic urethane bins for solid fuel propellants and gas generators based upon curing of glycidyl-azide polymer and isocynate curative mixtures. Void or bubble free propellant grains are obtained by employing a cure catalyst composed of a mixture of triphenyl bismuth and dibutyltin dilaurate, preferably in a respective ratio of about 10:1 by weight. The void free propellant grains have burn characteristics acceptable for missile propulsion applications.

Abstract: A method of preparing nitrile elastomer surfaces for bonding by epoxy adhves is presented. A treating solution comprising a dilute concentration of a mineral acid such as HCl in a carrier comprising water and either alcohol or ketones is prepared. The treating solution is applied to the elastomer surface with the surface being hydrolyzed in a mild manner thereby providing an improved adherable surface for covalent bonding by epoxy adhesives. A surfactant can be added to the treating solution for cleaning the surface to enhance the surface treatment.

Abstract: Reflector means is placed in the path of the energy beam of a radar to incept a peripheral portion of the beam and divert sufficient radar waves to cover a portion of the field-of-view in the opposite direction.
