Abstract: This invention encompasses a water-to-water heat-pipe heat exchanger having vessel, at least one partition dividing said vessel into at least two compartments, at least one of said compartments further having a fresh water input means and a fresh water output means, and a different compartment having a hot waste water input means and a hot waste water output means, and a plurality of heat exchange pipes for transferring heat between said compartments. The invention is generally in heat exchangers, and for dissipating heat in any system by transferring heat from a hot to a cool substance.

Abstract: This device is a modification to the basic auto-tracker function in missile uidance systems, and consist of three new auto-tracker functions. First the gunner has control of an extra set of crosshairs in the tracker output imagery. The gunner will position this crosshair on the desired impact point of the target while the auto-tracker is tracking the target and issuing guidance commands to the missile. The second part is a discrete command issued by the gunner to the auto-tracker. If the gunner decides his impact point selection is better than the auto-trackers impact point selection he simply commands the auto-tracker to enter the aimpoint bias mode. At this time the auto-tracker will stop tracking the old track point and start tracking the part of the image defined by the gunner controlled crosshair. The third part is the filtered transition of the auto-tracker error signal from the old track point to the new track point.

Abstract: Recovery and disposing of waste materials containing inorganic chemicals not be effected by incineration to meet environmental regulations as is the situation with waste organic materials. As long as the inorganic toxic materials are in some soluble form, they can pollute the environment, and, also, end up in the water supplies. Two different disposal methods are disclosed wherein one method is effective for removing the insoluble inorganic salts by converting them into mesylates by reaction with methanesulfonic acid or with methanedisulfonic acid. Most mesylate salts are highly soluble in aqueous and certain organic systems. As an illustration, 1.0 part of silver mesylate or 2.0 parts of stannous mesylate or lead(II) mesylate will dissolve in 1.0 part of water at room temperature. This unique solubilizing property offers the ability of leaching such toxic metal contaminants as lead, cadmium, etc. from sewage sludge. The metal salts can thus be recovered and recycled.

Abstract: Cadmium sulfide is formed successfully from the laser-induced chemical reion between a first reactant of a dialkylcadmium and a second reactant of a dialkylsulfide. Infrared laser radiation in the range of 10.4 or 9.4 micrometers is provided by a continuous-wave CO.sub.2 laser.

Abstract: A linear detector array is positioned a fixed distance behind a narrow slot n an opaque mask. The array is oriented perpendicular to the slot as viewed from the "front", or direction of laser energy arrival. Light from the laser source, limited by the mask and slot, falls on only a few adjacent elements of the detector array, depending on the direction of arrival of the light. Further, since such crossed linear elements (slots and array) provide this measure of angle of arrival in the single direction perpendicular to the slot, two such systems of mask, detector linear array, and processing electronics may be employed (one rotated 90 degrees with respect to the other) to provide `vertical` and `horizontal` measurements of direction to the laser source.

Abstract: A microphone such as that used in a shipboard public address system is ted for its output level by an integrated microphone tester. The microphone is secured in a specific proximity of a sound-level calibrator acoustic generator providing a known output level.

The tester assures an inherently high degree of reliability and enables relatively unskilled personnel to provide in situ testing with minimum disruption to the communication system with which the microphone is associated.

Abstract: The headset system utilizes the theory that unique sound waves can be added or subtracted without loss of information to attenuate the noise at the ear and mouthpiece, without lowering the noise level of the environment. This allows for clearer reception and transmission of communication. The system includes a directional microphone mounted on a headset/helmet, isolated from both voice and earphone output, level-setting and frequency tailoring circuits, and voltage summers and amplifiers. The microphone picks up the ambient noise, and the level-setting and frequency tailoring circuits produce a close approximation of the noise at the ear and mouthpiece (i.e., two separate matching circuits). This signal is then inverted (using an inverting buffer) to provide destructive interference.
