Filed:

Apr 18, 1983

Appl. No.:

6/486127

Inventors:

Donald W. Sweeney - Livermore CA
Neal C. Gallagher - West Lafayette IN
Charles R. Christensen - Athens AL

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

F41G 726

US Classification:

244 313

Abstract:

A beamrider guidance system for missiles wherein a laser beam is given two circular motions around the boresight axis to produce amplitude and phase modulation on the signal received at the missile. The information on distance from boresight is contained in the amplitude modulation and the angular information is contained as phase modulation. A laser optical system with a spinning holographic element provides one of the circular motions for the beam. The other circular motion is provided by a low frequency, circular scanning mirror.

Abstract:

Method and apparatus to enhance intermodal containers for transport of vehicles wherein multiple longitudinal rails on container walls support movable and removable transverse cargo pallets having foot members which are articulatably connected to the pallets are disclosed. Cargo, preferably an automobile fixed to front and rear pallets is loaded by inserting each pallet's feet onto appropriate rail(s) at door opening, then sliding to stowage spot, the rail selection determining height and tilt. Stowage of any mix of automobiles in intermodal containers is optimized by double-decking, half-decking, double half-decking, mirror-imaging, and envelope intervention. On back haul, pallets serve other cargo as restraints, hangers, pallets, or dunnage deck supports, or they are stowed out of the way. Method and apparatus permit automated load planning and container stuffing, and make containerized shipment of large volumes of automobiles cost competitive with current methods.
