Abstract: An apparatus for securing a cargo container having standard corner fittings ncludes a housing in which is mounted an elevator assembly for vertically positioning a platform with respect to the housing. The platform is adapted to engage a corner fitting when raised. The apparatus further includes a rotatable locking element carried on the platform which is rotated to lock to the fitting once the fitting is engaged. The platform together with the locking element can be further elevated when the fitting is engaged to raise a corner of the container or retracted within the housing to disengage and allow the container corner to clear the top of the housing.

Abstract: An integrated ambulator and wheelchair is provided to enable a paraplegic stand on the ambulator and be separated from the wheelchair for maneuvering in confined spaces. The ambulator has power operated articulated linkage for raising the paraplegic out of and free of the wheelchair to the standing position on the ambulator; the compact base of the ambulator containing a drive mechanism for moving the ambulator in any desired direction through controls conveniently located on an arm rest.

Abstract: A connector for holding and aligning optical fiber waveguides is produced subjecting a tube encompassing a wire mandrel to a high-energy forming process which forms the tube into an arcuate shape having a bore for receiving the ends of the waveguides.

Abstract: An apparatus for in-place grinding of the inner surface of huge cylinders mprises two adjustable spider ring assemblies which support a rotating rail assembly. A cage assembly is mounted on and rotates with the rail assembly and carries a grinding unit for grinding the inner surface of the cylinder.

Abstract: A method for deploying towed instrumentation arrays from vessels having miple submerged hulls is disclosed. The method significantly reduces the possibility of the array abrading or fouling upon any submerged structure or part of the vessel.

Abstract: A turning apparatus, intended to be mounted on a work shaft for in-place ting, may include a pair of mounting rings which are attachable to the shaft and which support a longitudinal annulate frame assembly which rotates about the area to be cut. A drive assembly is mounted on a mounting ring and engages a ring gear attached to the frame assembly for providing it rotational force. A longitudinal track assembly is mounted on and extends between the ends of the frame assembly. A carriage assembly is slidably mounted on the track assembly and is in operational engagement with a lead screw which is also mounted on the track assembly. The carriage assembly is adapted to hold a cutter for machining the shaft surface as the frame assembly rotates. A hydraulic indexing device incrementally rotates the lead screw in synchronism with the rotation of the frame assembly to move the carriage assembly and the cutter along the axis of the work piece.

Abstract: A bi-directional underwater communication system provides a submerged operator with the capability to communicate with a surface site. A face-mask-mounted microphone and an earphone are connected to a submerged, watertight radio. The radio antenna cable is carried by a buoy to the surface of the body of water in which the operator is submerged.

Abstract: The invention is an apparatus and method for multiplexing digital informan acquired from a multiplicity of data terminals distributed along a conductor of given length. A cyclic synchronization signal consisting of a stream of coding periods is transmitted upon the conductor. The duration of each coding period exceeds the two way travel time through the conductor. The leading edge of a coding period stimulates the transmission of one bit of a digital word stored in each terminal. The bits from the terminals arrive at a system receiver in a time sequence corresponding to the spatial distribution of the terminals. Bits are collected in storage registers according to their significance which is determined by the respective coding period during which they are received. A word from a particular terminal is derived by strobing the output of the storage registers at the time corresponding to the position of the terminal.

Abstract: An apparatus for decoding a Manchester encoded waveform is described in wh a gating circuit responds to the mid-cell transitions in the encoded waveform to produce an enabling signal which causes a clock circuit to generate high frequency clock pulses. A programmable counter accumulates the generated clock pulses. If the counter exceeds a clock count threshold set by a multiposition switch before the beginning of the following enabling signal, it causes a storage element to sample the encoded waveform and store the sample to provide an output signal representing decoded data. A second, substantially equivalent circuit decodes timing from the encoded waveform. The multiposition switch provides the apparatus with the capability to decode encoded waveforms of varying frequency.
