Wheel hub arrangement with three drum units comprising a hollow drum (), a winding of a flexible pulling element fixed on the drum, and a biasing spring () in the hollow inner space. Respective free-wheels () are provided at sides of the hub unit (). The wheel hub unit comprises a pair of spaced driving sleeves () arranged in axial direction and the sides of the driving sleeves facing to a drum unit and being connected therewith to transmit of torque only. The driving sleeves are surrounded by intermediate sleeves () and a spacing is formed between them, wherein a ball bearing () and one of the freewheels are arranged so that they are connected both with the outer surface of the driving sleeve and the inner surface of the intermediate sleeve. The intermediate sleeves are connected rigidly together and they are also connected at least during the driving sessions to an outer sleeve () of the wheel hub unit.

Wheel hub arrangement for a wheel drive by an alternating symmetric drive system using a flexible pulling element, that can be used in vehicles particularly in bicycles

Alternating drive primarily for bicycles and similar driven vehicles, in which the rotation of driven pedals are converted into reciprocating swinging motion of swinging arms, and the swinging arms have respective driving arms (') coupled to a head portion (&#x2032;) surrounding the swinging shaft () of the pedals from which a traction arm (&#x2032;) is extending out that closes an angle with the driving arm and the remote ends of the driving and traction arms () are interconnected by a connection arm (&#x2032;) A substantially triangular opening is formed between these arms, and the shaft of a driving wheel (&#x2032;) is positioned in this opening, the traction arm defines a traction path (&#x2032;), and a flexible pulling rope () that rotates the driven wheel of the vehicle is led around at least one rope wheel () that has a shaft () guided and led along the traction path for adjusting the transmission ratio.

Method for oxygen treatment of liquid unsaturated carbon compounds with carbon number between 6 and 26 wherein the material is placed in a reaction chamber (), a mixture ozone and oxygen is passed through the material, and by controlling the flow rate of the gas mixture through the material the temperature of the reaction is controlled to remain below a predetermined maximum value being 100&#xb0; C. As a result of the reaction a novel material is obtained which has an epoxy-structure, has a higher density and smaller viscosity than the starting material, it has excellent burning properties and can be used as a limited rate source of oxygen. The apparatus for carrying of the method comprises an oxygen source, and ozonizer (), a reaction chamber () for containing the liquid starting material, a gas pump () for removing the gas from the reaction chamber, and a temperature control system. An expedient field of application for the novel material is a therapeutic composition that facilitates natural metabolism of cells that comprises hydroxy proline and a neutral carrier material, wherein the amount of the material is below 20% and the amount of hydroxy proline is below 10%.
