Abstract: The pneumatic lumbar traction device comprises two separable parts, namely an upper hollow part and a lower frame, the frame having a pneumatically operated piston and cylinder mechanism fixed in and located centrally therein with a piston rod extending outwardly to engage a bar positioned to engage and move a loop fixed to a pelvic traction belt outwardly of a foot end of the device; the upper hollow part having an upper surface on which a user will lie during use; a generally elongate chest belt having opposite end portions with a strap fixed on each end portion with a first clip on said strap and a mating second clip fixed on the opposite end portion, each strap, after said mating clips are fixed together, being capable of being pulled through said first clip to tighten it on the first clip against said fixed mating second clip thereby to tighten the chest belt around a users chest; two, spaced apart, elongate strips of hook or loop material fixed to a central area of the upper surface for engaging with an

Abstract: A skirt panel is provided herein for interconnection to another abutted similar skirt panel for attachment beneath a lower, outer longitudinally-extending edge of a trailer including a rear wheel assembly of a tractor-trailer rig, thereby to provide a continuous fairing extending downwardly from the trailer. The skirt panel includes a monolithic, generally-rectangular composite reinforced thermoplastic structure, having vertical lateral side edges configured and arranged for connection to associated vertical lateral side edges of abutting similar skirt panels. This provides a longitudinally-extending fairing for extending contiguously on each side of the trailer, a front face of the thermoplastic structure being provided with a plurality of longitudinally-extending, vertically-spaced-apart arcuate protrusions. The outer face of the thermoplastic panel preferably also is provided with dimples.

Abstract: The measuring array with an earth connection point (5) for determining the insulation resistance (Riso) of an energized electrical apparatus or of an installation with a supply voltage UB with a positive pole (6) and a negative pole (7), two switches (S1, S2) or a corresponding two-way switch being provided for creating a current path between one of the two poles and said earth connection point (5) in order to determine the insulation resistance (Riso) generally obtained when one or a plurality of insulation faults occur at any potential reference, two measurements being performed one after the other for determining the insulation resistance, the first switch (S1) being closed and the second switch (S2) open during the first of these two measurements and the first switch (S1) being open and the second switch (S2) closed during the second of these measurements.

Abstract: A method of converting a direct voltage generated by a decentralized power supply system into three-phase alternating voltage by means of a plurality of single-phase inverters (WR1-WR3), said alternating voltage being provided for supplying an electric mains, is intended to avoid inadmissible load unbalances using single-phase inverters. This is achieved in that, upon failure of one inverter (WR1-WR3), an asymmetrical power supply distribution is reduced by limiting the output of the other inverters. The method makes it possible to simplify three-phase voltage monitoring.

Abstract: The subject matter of the invention is a bellows (1) of a connection between two hinge-linked vehicles (5, 6), said bellows (1), which comprises a bellows bottom (4), a bellows roof (2) and bellows side walls (3), forming a tunnel-like tube, said bellows bottom (4) being a removable constituent part of said bellows (1), said bellows (1) having a plurality of frames (10) disposed one behind the other in the longitudinal direction of said bellows (1), said bellows bottom (4) having a plurality of ledges (20) disposed one behind the other, there being provided, to connect a respective one of a frame (10) with a ledge (20), a spring cramp (30) taking hold of the frame and the ledge, said spring cramp (30) having at least one shoulder (33) for matingly connecting frame (10) and ledge (20).

Abstract: A method of matching the power of a photovoltaic system producing electric energy by which a working point at which the system produces maximum power is set by changing the working point in an MPP matching process and by comparing the system power, which changes as a result thereof, is intended to be suited both for stationary characteristic curves and for non stationary generator characteristic curves and to be easy to carry out so that the best working point is always set, even when the system is subjected to external interfering factors. This is achieved in that one or several additional control steps or control cycles are performed in order to track during the matching process a power point changing under external impact for a working point of even higher power to be set.
