Abstract: A foundation footing (30) has a support framework (32) encased within concrete (38). The support framework (32) includes elongate members (34) formed of timber, such as telephone poles, which extend the full length of the footing (30). Brackets (36) rigidly securing terminal ends (42) and intermediate portions (44) of the elongate members (34) in fixed relation. The brackets (36) have steel plates (46) disposed beneath the elongate members (34) and binding chains (48) secured to the steel plates (46). The binding chains (48) are preferably loosely secured around the elongate members (34) until being encased within the concrete (38), which rigidly secures the binding chains (48) to the elongate members (34) and the elongate members (34) to the steel plates (46). Grooves (86) are formed into the elongate members (34) to increase the bonding between the elongate members (34) and the concrete (38).

Abstract: A retaining wall system for use in retaining a backfill particulate mass is formed by at least one retaining wall unit. The retaining wall unit has a substantially upright forward wall having a rear surface for abutting against the backfill particulate mass. A substantially upright stem wall extends rearward from the rear surface of the forward wall. The stem wall has opposite substantially upright sidewalls. At least one of the sidewalls has a series of longitudinally spaced apart elongated grooves that slope upward toward the forward wall.

Abstract: A packaged stack of flat electrical components is held under controlled pressure in its supporting frame by a stack loader calibrated for applying the exact force required for good thermal and electrical contact. The stack is lowered or raised in the supporting frame by the stack loader. Stoppers on the supporting frame permit by lowering of the stack to disjoin the electrical components and make any device accessible for maintenance, testing or replacement. By choosing a progressive degree of displacement downward the electrical devices become accessible one after the other.
