Abstract: This invention relates to a gaseous medium flow distribution means for use in or in connection to a sterilizer chamber of the type in which a gaseous medium, such as steam or air, is brought to circulate. The means comprises cover means covering essentially a section area of said chamber, and said cover means are defining slits through which air is allowed to pass, said slits being shaped and distributed over the area so as to control the air flow inside said chamber in a predetermined manner.

Abstract: The invention relates to a method in autoclaves, the autoclave being divided into imaginary areas, the areas being heated by the feeding of steam into the areas in order to heat goods which have been placed in the autoclave so that it reaches sterilising temperature, whereby the feeding of heat between the areas is controlled. Such control is effected by successive registration of the temperatures in the areas and when the temperatures differ between the areas, the feeding of steam to the area which temporarily has a higher temperature is ceased, and as soon as the temperature in the adjacent area has passed the last mentioned temperature, the feeding of steam to that same area is resumed. In a device for the carrying out of the method, a temperature meter is arranged in each area.
