A system for effecting underwater compaction of submerged sand. The system utilizes a towboat that drags a vibratory compactor slowly over the sea floor as dredged sandy material is deposited. The travel route and speed of the towboat and compactor are coordinated with the dredge discharge rate and discharge location whereby the compactor completes one pass over the entire fill area for each predetermined increment of fill depth.

A remotely chargeable stuffing box adapted for below ground or other inaccessible installations includes telescopically arranged inner and outer members; the outer member being formed with a pair of axially spaced, annular, inwardly opening chambers pre-packed with a semi-plastic packing composition axially confined within each chamber by axially spaced annular sealing rings. An annular rib, which serves as a common boundary for the chambers is formed with an annular inwardly opening groove into...

A fill and relief valve arrangement for the introduction of fluid into and the selective venting of fluid from a fluid chamber includes a body having a stepped open-ended bore extending therethrough and an annular shoulder formed at one end of the bore. A valve seat element is sealingly secured within the other end of the bore and has a passage formed therein communicating with a passageway which communicates the bore with the fluid chamber. A fill valve is adjustably positioned within the bore ...

A nozzle for filling containers with fluent materials, including concentric tubes forming an annular space there between, a plurality of orifices providing communication between the inner and outer tubes and a dispensing opening for dispensing fluent materials.

A capacitor fill tube and seal combination is disclosed which comprises a fill tube and a plug seal device. The plug seal device comprises a short sleeve member having fill holes in the wall thereof and a threaded sealing plug or plug seat therein covering said fill holes. The sleeve is permanently mounted in a wall of a casing to project into the casing. A threaded fill tube is then threaded into the sleeve and initially engages the plug seal to move the plug further into the sleeve and away fr...

A vapor loss control system for a vehicle fuel supply system includes a first vapor recovery circuit from a vapor space of a gas tank to an air purged canister having a first predetermined volume of vapor adsorbing active material; and wherein the outlet of the canister is connected to a ported vacuum connection in a carburetor for selectively purging said first canister during each engine operation at a rate to purge said first canister for subsequent recovery of vapors. The system further incl...

A left zero fill circuit particularly suited for incorporation into non-buffered keypunch machines for providing a left zero fill capability thereto. The circuit provides a combination of registers and memory storage devices operable in an input mode to accept keypunch data, and in an output mode to punch the data onto a card in the proper locations within the field. The circuit further includes isolation means interposed in the interconnections between the keypunch machine and the left zero ele...

The modules of a modular bowling lane system are fabricated at a manufacturing facility. Each lane module includes a rectangular deck formed from a plurality of hardwood strips adhesively bonded side by side in a single layer. A plurality of box channel supports are coupled at intervals to the lower surface of each lane module and extend laterally across the module. One end of a jack screw is coupled to each end of each box channel support while the other end of each jack screw is coupled to the...

An apparatus for filling a flexible container has a filling head and a pair of closure removing heads so that while the one container is being filled a filled container is closed and another prepared for filling.

An improved liquid gas contact tower of the type having film fill placed in the tower with its principal plane inclined at an angle to the vertical so as to intersect a gas path extending between gas inlet and outlet openings includes a plurality of dewatering sheets secured to the film fill adjacent its lower surface to intercept liquid collecting and flowing along the film fill sheets and deflect it away from the fill, thereby to decrease the air pressure drop through the film fill during use.
