Patent DE-3923641-A1 (DE)
Title: Procedure for thermal aerobic compositing of organic waste materials - in which air passed through composting bed is dried and filtered before release and heat and moisture recovered are returned to compost
Inventor: BERLEPSCH FREIHERR VON
IPC: C05F17/00
Filed: 1989-07-17
Abstract: The organic material is composted in a reactor in which it travels through zones of different degrees of decomposition into which controlled quantities of air are introduced. The exhaust air from the pre-rotting and principal rotting zones is withdrawn downwards and the moisture it contains is recovered and returned to the zones in question.  The heat in the exhaust air is used to pre-heat the air entering the reactor. The temperature, moisture content, entrained gas content and oxygen content of the exhaust air are measured and used as parameters for controlling the composting process. USE/ADVANTAGE - This invention is used in the thermal aerobic composting of organic waste. The corrosion of surrounding building elements produced by the condensation of acids and salts from the exhaust air is avoided while at the same time ensuring optimum conditions for the composting process.

Patent DE-4006091-A1 (DE)
Inventor: TSCHUMI OTTO
IPC: B01F5/02
Filed: 1990-02-27
Abstract: The assembly contains a flow of mixture and devices arranged about this, to spray water into the mixture. Two cylinder sleeves (3, 6) form part of these devices, one (3) of which is held firmly during operation in an unchanging position, while the second (6) is formed and elastically held by two spring-loaded ring discs (5, 9) such that it may slide away from the first, parallel to the axis, due to the pressure of the water to be injected, against the force of these spring-loaded discs (5, 9) and a further elastic support (10), so that a gap is formed between the frontal surfaces of the two cylinder sleeves. This serves as a ring nozzle for the water to be injected. Its aperture enlarges as the pressure increases, the result of which is that the velocity of the emerging water is independent of the quantity of water, so that the depth of penetration of the water jet into the flow of concrete is independent of the quantity of water. The quantity of water itself is regulated by a valve (11) in the water feed pipe (12). <IMAGE>

Title: Book preservation treatment
Inventor: BEYER GOTTFRIED DR ING
IPC: D21H25/18
Filed: 1991-04-30
Abstract: To protect books, using a gas or mist preservation medium, the medium is delivered as a gas and/or an aerosol in a compressed air stream.
