Title: Recovering heat from liq. compost - by aeration with air or oxygen and removing heat of biological oxidn. by heat pump
Inventor: ANDERS GEORG
IPC: A01C3/02
Filed: 1979-07-16
Abstract: In withdrawing heat from liq. compost in containers, trenches, and/or stables, the compost is aerated by atmospheric air or oxygen and the heat generated in the compost by the resulting biological oxidn. process is withdrawn by way of energy collection leads, grids or plates in the walls of the container or stables or in the space above the compost, to feed a heat pump. The process is esp. useful in an integrated system of stalls for animals which create the liq. compost. On aeration, this can be used to create heat for warming the stalls. By using reversible heat pumps., heat may if necessary be extracted from stalls and passed to the liq. compost supply, where it serves to activate the oxidn. organisms. The oxidised compost has low odour and is environmentally harmless, and can be used directly for spreading on the fields, whilst the heat produced provides a reduction in energy costs for the compost treatment and in stall heating.

Patent DE-3100014-A1 (DE)
Title: Infinitely variable transmission for machine tools
Inventor: SCHIWECK HEINZ
IPC: F16H37/08
Filed: 1981-01-02
Abstract: This invention is an infinitely variable, mechanical transmission. With its high control range (range utilisable in practice = 200:1), it is used mainly as a main transmission for machine tools, in which case the entire speed range can be covered in an infinitely variable manner. This transmission can also be constructed for certain fields of application as a so-called +/- transmission or 0-transmission. The transmissions, of mechanical or hydraulic type, hitherto customary in machine-tool building only have a max. control range of 30:1 and therefore necessitate additional multi-step reduction transmissions. The present invention consists of an infinitely variable transmission of known type, which functions as a control gear, and of a differential gear. Both main transmission groups are driven centrally by an electric motor (see drawing, sheet 1, Fig. 1). By the special arrangement of the control gear with the differential gear, a multiplication of the control range of the infinitely variable transmission used is obtained. This transmission is only comparable with the Patent Application German Offenlegungsschrift 2645577. Instead of the differential gear, an epicyclic gear is used here as differential. However, the possible extension of the control range is smaller when an epicyclic gear is used. <IMAGE>
