Abstract: An arrangement determines the height of a multilayer stream of articles such as the rod-shaped cigarettes of the tobacco industry. The arrangement includes a flexible elongate member connected to move up and down with the uppermost articles in the multilayer stream as the height thereof varies. The flexible elongate member has a first end fixed in place and an opposite end connected to a weight which moves in a vertical direction as the flexible elongate member moves up and down in response to the height of the multilayer stream of articles. The flexible elongate member is trained around an idler roller, and a sensor is spaced directly below the weight for determining the elevation thereof. Such elevation is directly related to the height of the multilayer stream of articles.

Abstract: A plastic film covers the compost in a mushroom bed during the spawn run step of the mushroom growing procedure. It is during this step that the spawn begins to colonize the compost with mycelium. The plastic cover is vented by having a pattern of symmetrically arranged holes throughout its area so as to prevent or minimize moisture loss and prevent airborne pathogens from landing on the compost. The vented cover also reduces the CO.sub.2 level while increasing the oxygen rate.
