Abstract: A portable radar simulator which when connected to a transmitting means s as a waveguide horn antenna provides a radar signal to test a radar receiver. The portable radar simulator comprises a tunable oscillator which generates a continuous wave signal in the microwave frequency range with the desired frequency of the signal being selected by an operator. The signal generated by the tunable oscillator is supplied to a microwave switch.

Abstract: A vane type hydraulic energy translating device for pumping filtered seawater and which uses seawater as a lubricating fluid. The pump is a compact, light weight design in which the bearings and certain other critical components are fabricated from corrosion resistant, low friction, high strength materials. The vanes as well as flexible side plate members are formed of these corrosion resistant materials. The pump body is formed of high corrosion resistant stainless steel. The side plates are flexible and act as wear surfaces for the ends of the vanes as well as sealing surfaces about the rotor thereby preventing leakage of seawater from high to low pressure areas. Each vane is spring biased radially outward from the rotor axis with four springs disposed within apertures located in the vane base. The vanes are generally rectangular in shape and have an outer end portion which serves as a sliding seal against a cam ring track.

Abstract: A system for installing a plastisol or similar compound into the interior ace of a spent squib-activated countermeasures cartridge. When the squib ignites and expels the countermeasures payload, the heat of combustion causes the plastisol to soften, react and expand to fill the empty container remaining after payload ejection. The foam filled container then acts as a radar absorber instead of a radar reflector and thus counters dispenser observability to RF energy.

Abstract: This invention pertains to a rotary disk tool which utilizes pressurized water as the working fluid. When an operator engages a trigger on a novel control handle and valve assembly, pressurized seawater enters the rotary disk tool through the control handle and valve assembly into a seawater powered vane motor. The shaft of the seawater powered vane motor, is coupled to a drive gear. The drive gear, in turn, is in operative engagement with a driven pinion coupled to an output shaft which drives an abrasive disk. Seawater exhausted from the motor into a gear and pinion housing provides lubrication for the drive gear, driven pinion, and the bearings used with the gear and pinion. The seawater is then exhausted from the housing as a fan spray directed onto the back of the abrasive disk so as to reduce drag of the disk in water and to flush away loose material from the work surface.

Abstract: Certain derivatives of the lanthanide elements greatly enhance the strength of heated alumina refractories in the 500 to 1000 degree Fahrenheit temperature range. Cerium oxide, for example, when added in 1 percent to 5 percent by weight to commercial calcium aluminate cement with tabular alumina aggregate, plus 10 to 30 percent water, and fired at 500 to 1000 degrees Fahrenheit, forms a ceramic bond and becomes as strong as untreated calcium aluminate refractory concrete fired at 2000 degrees Fahrenheit. The cerium modified refractory concrete is 1000 psi to 1500 psi stronger than unmodified refractory concrete at 500 to 1000 degrees Fahrenheit.
