Abstract: An improved impersonal eyepiece for astronomic positioning is affixed to an optical viewing device to provide a means for observing the position of a celestial object at timed intervals. The viewing device produces a source image of the celestial object and a light source in the eyepiece is energized at timed intervals by a control circuit to illuminate a reticle mask and to thereby superimpose a reticle reference image on the source image during each of the timed intervals. The position of the celestial object with respect to the illuminated reticle is noted during each timed interval and the data so obtained is used to define a reference position.

Abstract: A laser projection and printing system wherein a laser beam is focused on e scan center of an X-Y galvo-deflector, passes through a condensing lens to a transparency to be projected, and is transmitted to an imaging lens for projection to a large format plate. The scanning galvinometer, condenser, and imaging lens render the laser beam effective to project the small transparency to a large format plate.

Abstract: A spudwell cooperating with a pipe pile and a jacking mechanism for elevag a pontoon section above a body of water. The spudwell straddles the pipe pile through a pair of vertically aligned apertures through which the pipe pile extends. A plurality of pins rigidly affixed to the spudwell are aligned to extend through holes located in the pontoon section. When extended through the holes in the pontoon section, a securing plate engages the pins thereby securing the spudwell to the pontoon section. A pair of chains from the jacking mechanism are connected to the spudwell via a motion compensation system incorporated therein.

Abstract: A solar still apparatus having a condensation chamber is disclosed. A plurality of hollow columns are connected to the chamber at the open upper ends of the hollow columns and the lower ends of the hollow columns are adapted to engage a support surface for the still apparatus. The hollow columns also function to contain distilland liquid and to support parabolic solar collectors for heating the liquid to form vapor at the upper end of the hollow columns. The vapor is introduced into the condensation chamber for condensing to form a distillate liquid. Means including a shield and an evaporative surface layer are disclosed to aid the cooling of the condensation chamber relative to the vapor to facilitate the condensation of the vapor in the chamber.

Abstract: An automatic electrical load matching device for applying loads to wind den generators. The device switches five different loads to the output of a wind driven generator. Each load corresponds to a range of speeds of the wind driven generator's rotor.

Abstract: A rotary engine has a housing and a pair of spaced, coaxial rotors in the housing connected for joint movement. Each rotor rotates in a separate rotor chamber, and each carries radially movable vanes, the outer edges of which engage the configured inner surface of the housing. An axially extending passage in the housing communicates the rotor chambers. The parts are few in number and readily made.A method of operating such a rotary engine in either gasoline or diesel modes, includes the addition of additional fuel after initial combustion.

Abstract: A hollow, projectile-shaped body containing an acoustical transducer is rased into the sea such that the body descends in free fall until it strikes and penetrates the sea floor, coming to a rest therein. Acoustic signals emanating from the acoustic transducer are processed to generate a direct current analog signal which is a function of the acoustical attenuation of the acoustic signals from a time immediately preceding the body striking the sea floor surface until the body comes to rest in the sea floor, thereby obtaining an indication of the physical characteristics of the sea floor.

Abstract: A chain jack utilizing two chains is operated by alternately transferring e chain load from latches incorporated within an upper latch assembly to latches incorporated within a lower latch assembly while moving the upper and lower latch assemblies away from and toward each other by alternate extension and retraction of a hydraulic ram to cause relative movement between the chain and the lower latch assembly. Actuation of the latch mechanism is controlled by hydraulic connection to a pair of four-way valves operated by a control piston having followers from the four-way valves engageable thereon. The control piston is disposed to move with the upper latch assembly while the followers are rigidly affixed to the lower latch assembly. Thus, the engagement and disengagement of the latch mechanisms with the chains are synchronized by the relative movement between the lower and upper latch assemblies.

Abstract: A coaxial wet connector for connecting coaxail conductors of electromechaal ocean cables underwater either by a diver or submersible manipulator. The connector comprises a male section having a male inner conductor extending outwards from a concentric male outer conductor and a female section containing a spring biased shuttle piston for receiving the male inner conductor upon mating. An O-ring wiping seal wipes the male inner conductor clean of water as the male inner conductor drives the shuttle piston rearward within a female housing until electrical interconnection between the male and female sections is completed. A pressure compensating bladder removes water trapped adjacent an interconnection surface during mating and returns the water to the interconnection surface during decoupling thereby preventing a hydraulic lock between the male and female sections.

Abstract: An ignition device for igniting a rocket motor comprising a striker adapted or displacement by pressure generated by an auxiliary charge, a percussion-operated priming device for impact by the striker, and an ignition charge for ignition by the priming device and for igniting the rocket motor. The striker, in its inoperative position, is mechanically keyed within a hollow container body having an axial bore therethrough by a pair of diametrically opposed circumferential grooves within which an O-ring is retained. For operation, a fluid generates pressure on the striker, thereby dislodging it from its mechanical keying and driving it to impact the percussion-operated priming device.
