Abstract: The invention provides a detector for detecting air components, e.g. contaminations, and in particular noxious or poisonous contaminations, which device comprises a housing in which an air pervious carrier containing a first reagent is arranged, this detector being adapted to draw air to be tested through said carrier so as to expose this reagent to the air, this reagent being influenced by the components to be detected, which carrier is to be contacted with a second reagent which, together with the first one, can bring about a colour reaction depending on the fact whether the first reagent has been influenced or not. The housing forms, in the operative condition, an integral unit, an air- and liquid-tight container with a rupturable wall and containing a not contaminated liquid contributing to said colour reaction being arranged within said housing, the latter being, furthermore, provided with a yieldable wall portion and a plurality of piercing pins arranged in such a mutual spatial relationship that the container can be pierced by pressing inwards said wall portion, so as to moisten said reagent carrier with the liquid from said container. In particular the second reagent can be contained in a similar second carrier which is normally separated from the first one but is contacted therewith when pressing inwards said wall portion.

Granted: 1987-10-28
Abstract: A process and an arrangement for the formation of an ignitable mixture from liquid fuel and combustion air, wherein preheated combustion air is conducted with a flow chamber along a surface which is moistened with fuel for take-up of fuel. In the process and arrangement, combustion air is conveyed into the flow chamber in the flow direction of the fuel which streams off the surface moistened by the fuel under the effect of gravity. Achieved hereby is an intensive contacting between the combustion air and the fuel. The fuel is dosed in excess so as to constantly afford a sufficient quantity of fuel for vaporization. During the through flow of the combustion air, there is formed, in the contact with the fuel, a saturated fuel-air mixture in conformance with the temperature of the preheated combustion air and the temperature of the fuel. Concurrently, care is taken that the trickling film of the fuel which is formed by gravitation as well as the drag effect exerted by the combustion air passing through the flow chamber can freely exit from the flow chamber at the foot of the surface moistened by fuel, to the extent in which the fuel is not taken up through vaporation by the combustion air in the flow chamber.

The blade rolls are each also provided with a pair of axially spaced thrust wheels, with the thrust wheels being positioned outboard of the blades and being equal to or slightly greater in diameter than the predetermined diameter of the blades. Driving means are provided in the apparatus for rotating the anvil roll in one direction and the blade rolls in an opposite direction. Biasing means are also provided for forcing the outer peripheries of the thrust wheels and the anvil roll into hard contact with one another thereby to maintain fixed the spacing between the cutting surfaces of the blades and the outer surface of the anvil roll notwithstanding the separating forces caused by the movement of a tire between such surfaces.
