Abstract: An apparatus for making radiographic pictures of an object submerged in a liquid comprising a substantially watertight housing having a reduced central section provided with a liquid displacing seal. The object to be irradiated is receivable in the reduced central section adjacent the liquid displacing seal. An irradiating camera is rigidly mounted in the housing. A sensitized film is additionally placed in the housing, oriented to receive radiation from the radiation camera after it irradiates the submerged object. In the preferred embodiment the reduced central section is a semicircular notch permitting irradiation of a partial section of the submerged object (see FIG. 1). An alternative embodiment has a hinged circular reduced central section permitting irradiation of an entire cross section of the submerged object to be irradiated. The apparatus can be transported underwater, mounted and actuated by a single operator.

Abstract: A specialized, reusable container for paint including an outer, bottom drip-catching body and an inner, main body for holding a supply of paint and a handle extending from the bottom section to the main, paint-containing section at and attached to the rears thereof. Included within the main, paint-containing section is a lateral, rotatable wire used to wipe the paint brush after the brush is dipped into the paint contained in the main body. Also included at the front of the bottom section is a projecting lip which defines a paint brush support in conjunction with the front wall of the inner, main body. The two sections of the container are preferably rectangular in horizontal configuration, with the inner, paint-containing section offset to the rear of the bottom, drip-catching section but still spaced therefrom to form a small gap.

Abstract: A lawn mower of the sickle-bar type having an elongated straight double-edged blade mounted at either end by a planetary mount producing in the horizontal plane a generally laterally reciprocating motion combined with an orbital motion creating cutting forces in both directions with the double-edged blade. The basic support wheels, handle and blade mounting and driving system are so mounted to allow one of the cutting sides or edges of the blade to be used for usual lawn mowing operation, which side is located well within and under and centrally to the basic mower structure, and the other, opposite cutting side to be used for trimming close to walls, trees, etc., which side is located at and moves past the end of the basic mower structure. The handle is reversible from one side to the other to allow the operator to move to and push from the appropriate side, depending on whether mowing or trimming operation is desired.

Abstract: A heavy duty moving system including a base sled having two sets of integral, drop-leaf, heavy duty caster wheels (FIG. 1) and a lever arm assembly (FIG. 6) for moving heavy equipment, for example, the "XEROX" copy machines of the 2400 series. The sled is slid under the machine (FIG. 8) and then raised at one end by the lever arm assembly (FIG. 9), after which one set of integral, drop-leaf caster wheels are lowered into position and locked. The opposite end of the sled is jacked up and the second set of integral, drop-leaf caster wheels are lowered and locked into position after which the lever arm assembly is removed. The machine then rests on the sled and its caster wheels and is ready for transportation. The machine is taken off the moving system in the opposite manner.

Abstract: A high fidelity loudspeaker system involving a multidriver, semi-omnidirectional, full range, electrodynamic loudspeaker including two, separate but complementary, closed box-like enclosures, an upper unit containing an array of mid-range speakers around three sides and a lower unit containing arrays of low and high frequency speakers around three sides. The low frequency speakers (woofers) on their interior sides include a series of tubes opening into the closed interior of the speaker enclosure, having various lengths in accordance with certain relative, locational relationships. Although the low and high frequency speakers include a single crossover frequency circuit, the "mid-range" speakers are not included in any crossover network but are driven throughout the total frequency input range, although a capacitor can be included to cut off the very low frequencies to the mid-range speakers.

Abstract: A method and technique for a deviated (non-vertical) emplacement of a conductor casing at a desired curver and orientation in order to facilitate directional drilling of a well in the substratum of an offshore well site. The method provides for the installation of a relatively short, offset portion of the conductor casing at only the bottom of the conductor pipe string and thereby utilizing this offset portion to force the conductor string in a desired direction and orientation by driving or forcing the conductor casing through a substratum in such a manner that the casing will assume the desired curvature and direction as it advances through the substratum. In addition to the offset or dog-leg segment at the bottom, key-way type guide bars can be added in the longitudinal direction to resist undesired rotation of the conductor pipe.

Abstract: An improved method of and structure for mooring for example supertankers offshore which combines the mooring process and the connections of cargo transfer lines into one simple operation and includes a mooring buoy capable of fluid transfer which is particularly adaptable to a super port type operation. The buoy includes a relatively long flotation caisson structure having a relatively small diameter, such proportion insuring greater stability in rough sea conditions. A flow line is located down the center of the buoyant caisson and extends above the bow of the ship it will service. A fitting is located on the top end of the flow line which is capable of securely attaching to a mooring pedestal located on the bow of the ship. This arrangement allows fluid flow between the riser structure and the ship as well as forming a substantial mooring linkage between the ship and the anchor lines which are attached to the bottom of the buoy. The system also includes the use of a mooring winch on the ship.
