Abstract: Provided is a lifting device comprising: a hook or clip; secured to the hook or clip, one or more first pulleys; a second hook or clip; secured to the second hook or clip, (i) a release mechanism comprising a second pulley and a releasable lock for an engaged flexible serpentine article and, optionally, (ii) one or more third pulleys, the second and third pulleys collectively the beta pulleys; and the flexible serpentine article engaged, at a first end, to one or the other hook or clip, and serially engaged through the first pulleys and beta pulleys, to provide a nominal two-fold or greater mechanical advantage, wherein the other end of the serpentine article is last engaged, among above recited elements, by one of the first pulleys.

Abstract: Provided is an electrical distribution device having three or more lateral surfaces, wherein at least two lateral surfaces are adjacent pyramidal surfaces, wherein each such adjacent pyramidal surface comprises a directionally biased power receptacle, wherein each such adjacent pyramidal surface is adapted to direct a bulky end of a transformer fitted therein downwards or in a lateral direction; wherein for downwardly-biased pyramidal surfaces, the portion of the pyramidal surface below the power receptacle is adapted to accommodate about two inches or more of a bulky end of a transformer fitted in the power receptacle; wherein laterally-biased pyramidal surfaces are adapted so that any transformer that extends over an edge of the relevant pyramidal surface towards an adjacent pyramidal surface so extends at an angle such that a transformer of high primary bulk could still be accommodated fitted into the biased power receptacle at such adjacent pyramidal surface.

Abstract: Described is a carrier system comprising a releasable adjustable fastening mechanism and a serpentine article engaged in the releasable adjustable fastening mechanism. The serpentine article is fixedly attached to itself to form a loop of strap, the strap extending in two directions from the loop.

Abstract: A buckle for maintaining tension in a serpentine article includes a main buckle structure having an internal chamber and at least one load bearing portion therein and rotable mounted therein a cam also having at least one load bearing portion. The cam can rotate between first and open positions so that, in the first position, a serpentine article with which the buckle is used is pinched between at least one load bearing portion of the main buckle structure and at least one load bearing portion of the cam; thereby maintaining tensile force or tension in the serpentine article and transmitting same to a structure to which the buckle is coupled at the coupling portion of the main buckle structure.
