Abstract

The invention relates to a spoke wheel rim (1) for a tubeless tire, comprising a rim ring (2), which has a rim base (3) and two rim flanges (4), and spokes (5), which connect a hub to the rim ring (2). It is essential to the invention that - grooves (6) which run in the circumferential direction are provided on the rim ring (2), each spoke (5) engaging with a complementary spoke head (7) in said grooves, - each spoke head (7) has a through-opening (9) which is formed transversely to the spoke axis (8), - each groove (6) is provided with a screw (10) which crosses through said groove and is screwed from the outside, and - each screw (10) is screwed through the through-opening (9) of the spoke head (7) into a screw opening (11) of the rim ring (2) so as to come into engagement, and the spoke (5) is thereby fixed.

Abstract

The present invention relates to a device for performing an Organic Rankine Cycle-process (ORC-process), comprising a first circular flow in which a first process fluid is conducted, having an evaporator for evaporating the first process fluid, an expansion machine located downstream of the evaporator for expanding the evaporated first process fluid, wherein the expansion machine is connectable to a generator for generating electrical energy, a first condenser located downstream of the expansion machine for condensing the expanded first process fluid, and a first fluid energy machine located downstream of the first condenser for increasing the pressure of the condensed first process fluid and for transporting the first process fluid to the evaporator that is located downstream of the first fluid energy machine. The term fluid energy machine is to be understood to describe a machine that exchanges mechanical work with the process fluid.
