Abstract: A housing for an electronic device or other object formed from a fiber-in-matrix material. A layered fiber-in-matrix type material, such as CFRP, may be used. A spine made from CFRP may support, and be attached to, a CFRP skin. The CFRP spine may be a unitary frame that imparts strength and rigidity to the overall housing and also form at least some of the corners of the frame. In some embodiments, the spine may be rectangular. The skin may be formed from multiple layers of CFRP type material stacked atop each other. Each layer may be cut at one or more corners to expose at least a portion of the layer beneath. The skin may thus have an overall cross shape, such that each arm of the cross may be wrapped around a different side of the aforementioned rectangular spine.

The ribs and the walls are further coupled by use of wood sheeting along the top of the structure to form the resultant assembly. The entire assembly is connected together with a series of bolt and steel angle connectors, allowing the entire module to act monolithically.

Abstract: Disclosed is a grid-shaped mat which is used especially for protecting floors or strengthening a floor cover. Said grid-shaped mat comprises a number of strip-shaped elements (1, 1?; 1?) which are bent several times, extend in a longitudinal direction (A), and form the grid structure of the mat (10).

At least two adjacent elements (1, 1?) are hingedly connected to each other with the aid of at least one pin (2) that extends in the longitudinal direction (A) of the elements, respectively. Such a mat is easy to produce while the floor cover that is applied to the mat coheres significantly better after drying and hardening than when a conventional wire grill is used.

Tubing elements of one row intersecting and secured to the tubing elements of the second row without mechanical fasteners. Discreet interference fit tolerances facilitate the construction of a non-welded, stress distributing structure highly suitable for earthquake resistance and wildfire survival.

A barb is provided in proximity to the pointed end of the shaft and presents a reentrant tip spaced laterally of the shaft and disposed in a direction opposite the point on the shaft. A bridge spans between the barb and shaft. The point permits facile penetration of both sheets with the crown limiting the extent to which the shaft can penetrate the first sheet. The reentrant tip on the barb permits facile retropenetration of the second sheet, and the bridge engages a sufficient portion of the second sheet to preclude withdrawal.

Abstract: A series of upright, longitudinally extending baffles are supported in parallel array, with the transverse or secondary baffles being formed by twisting out of the webs of the primary baffles an area initially separated by slots which leave a stem connecting the secondary baffle with the web at two opposed positions, normally the top and bottom. When the secondary baffle is twisted, each of the webs is twisted, as to 90.degree., to support the secondary baffle transversely to the primary baffles. Normally, the secondary baffles extend the same distance to each side of the corresponding primary baffle. The secondary baffles of one primary baffle are normally interspaced with the secondary baffles of the adjacent primary baffles.
