Abstract: A food storage apparatus comprises a frame defining a forwardly open space adapted to receive a plurality of food storage containers. The frame, which can be slidably mounted on a support within a refrigerator, includes inwardly projecting flanges adjacent its upper portion, and two pairs of front-to-rear extending bars located adjacent a lower portion of the frame. The bars of each pair are parallel and spaced horizontally apart. Each container includes outward flanges slidably disposed on the shoulders, and a boss projecting downwardly from an underside of the container and situated between a pair of the bars.

Abstract: An improved concrete lining machine is provided for lining the walls of a bored tunnel. The machine typically consists of three separable machine sections each having a frame and a plurality of supporting plates rotatable in an endless loop chain. Fresh concrete is sealed from the second machine section by a plurality of adjoining main and auxiliary plates which remain in place relative to the concrete until the concrete is at least substantially cured. According to the method of the present invention, the first machine portion partially supports the bored tunnel walls, and a third machine portion partially supports the curing concrete. The cost of tunnel lining according to the techniques of the present invention has been substantially reduced, and the machine may be placed directly behind a tunnel boring machine.
