Studies on transportation of fish. Pt. 1. Packaging of frozen fish in insulated containers

The paper deals with certain technological aspects of transportation of fish. Frozen fish packed in thermocole insulated plywood box (tea chests) and transported has been found to remain in good condition, for 3 to 4 days. Fish reaching the destination in a thawed state can be stored in crushed ice for a further period of 2-3 days. The effect of initial temperature of frozen fish on the storage life, the maximum storage period for different types of frozen fish packed in the insulated container and the changes in chemical and organoleptic qualities of different varieties of fish under condition of transport are also discussed.

Transportation of fish in India: problems and prospects

India has a long coast line of about 4,800 km along which fish landing centers are scattered. Fish catches are showing an upward trend consequent on rapid mechanization of fishing crafts. Economic utilization of the landed fish is an essential prerequisite for the proper development of Indian fishing and fish processing industries.

IMPORTANCE OF TRACK DESIGN IN GROUND TRANSPORTATION SYSTEMS.

The development of the tracks for the Tracked Hovercraft and Bliss Pendair Systems is described. Comment is made on the relative importance of track and suspension costs and of the need for tracks that are weather, vandal and noise proof. It is argued that the beam section required for a suspended air cushion is more likely to fit these requirements than that for beam riding vehicles, either air-cushion or magnetically suspended.

Development of an Active Superconducting Magnetic Bearing

The potential use of YBa2Cu3C7as an active component in a magnetic bearing is being investigated. Measurements are being made of the load bearing capacity and related stiffnesses in comparison to predictions from the critical state model. Although the load bearing capacity is high and increases with the square of the magnetic field trapped the stiffness is low. We report on a novel design concept to overcome this problem. © 1995 IEEE

Active roll control of an experimental articulated vehicle

A new experimental articulated vehicle with computer-controlled suspensions is used to investigate the benefits of active roll control for heavy vehicles. The mechanical hardware, the instrumentation, and the distributed control architecture are detailed. A simple roll-plane model is developed and validated against experimental data, and used to design a controller based on lateral acceleration feedback. The controller is implemented and tested on the experimental vehicle. By tilting both the tractor drive axle and the trailer inwards, substantial reductions in normalized lateral load transfer are obtained, both in steady state and transient conditions. Power requirements are also considered. © IMechE 2005.
