Abstract: The invention relates to a vehicle wheel assembly, comprising 1) a wheel rim having two opposed circular rim flanges; 2) an outer tire having two beads secured at the circular rim flanges; 3) an inlay; 4) a non-pneumatic inner tire comprising expanded thermoplastic polyurethane (E-TPU), which inner tire is enclosed by the outer tire, the inlay and the wheel rim. The inner tire in the assembly is in a compressed state S1, which state is compressed as compared to a relaxed state S2 when the inner tire is not enclosed by the outer tire, the compression being such that the cross-sectional surface area SA of the inner tire, which area is perpendicular to the plane of the tire, is smaller in state S than in state S2.

Abstract: Tire, comprising an annular massive tire body having an essentially round or oval cross section having a centre MB, and having an outer circumference Co forming a tread and an inner circumference Ci facing the centre of the annular body, the body containing a longitudinal pull cable channel, the channel containing a pull cable and having a cross section having a centre MK, wherein the distance between MK and the inner circumference Ci is between 7 and 18 mm measured along a line connecting MK and MB and structure comprising the tire mounted around a wheel rim.

Abstract: Disclosed is a device for checking the energy level of a battery, or battery pack, of the type used in the powering of transmitters, receivers and servos used in powered model airplanes, boats, cars, etc. The circuit connects a silicon controlled rectifier (SCR) and two light emitting diodes (LED) so that the diodes give a no, no-go indication of the battery's available output compared to a predetermined standard. Initially, in the checking procedure, the battery has power withdrawn through a load resistor prior to the final go, no-go indication.
