Abstract: A process and equipment for disinfecting bulk foods or animal feeds on a ship are described. According to this process, either before beginning to fill the cargo hold or when beginning the loading operation, a fumigation system is placed in the cargo hold and includes line sections that extend from the loading hatch to the bottom of the hold and are provided with gas passages at least in the vicinity of the bottom of the hold, and after filling the cargo hold, the end of the fumigation system which projects cut of the bulk material is connected to a centrifugal fan and the preparation which releases the gas is placed on in the surface of the bulk material and the fan is turned on and the cargo hold is sealed so that it is airtight. By operating the fan, the gas is pulled out of the gas space above the bulk material and directed into the bulk material from the bottom through the fumigation system.

Abstract: In a ship having a hull, a loading hatch, and a cargo hold which has a bottom and may contain a bulk material and a preparation that releases a pesticide, a device for disinfecting the bulk material comprising line sections of a total link which may be adjusted to the height of the cargo hold and a mechanism for detachably mounting the line sections to the ship. The line sections are joined together and have a first end portion disposed at the bottom of the cargo hold and a second end portion disposed in the vicinity of the loading hatch. The first end portion of the joined line sections have a plurality of gas openings and the second end portion of the joined line sections is connected to a centrifugal fan so that the pesticide-enriched air may be circulated through the bulk material.

Abstract: Measuring the mass flow of a liquid gas pumped from a storage tank to a consumer through a measuring station, includes the steps of throttling the flow of the liquid gas by a throttle in the measuring station; measuring the flow of the liquid gas according to the relationship ##EQU1## WHEREIN M is the flow rate, C and m are instrument constants evaluated by calibration, .DELTA.p is the head difference and .rho. is the liquid density; maintaining the delivery pressure of the liquid gas higher than its vapor pressure plus the maximum momentary head difference at the throttle; and compensating for the temperature-caused liquid density variation, including the steps of measuring the temperature of the liquid gas by a semiconductor having a resistance/temperature curve and adapting the curve to the density/temperature curve of the liquid gas.
