Title: Utilising process heat in cement-clinker process - thus reducing amt. of energy needed per tonne of prod.
Inventor: STRACH LOTHAR
IPC: C04B7/47
Filed: 1990-04-19
Abstract: In the energy flow produced during the cement-clinker process, the hot clinker is introduced into a heat exchanger after leaving the rotating oven giving a temp. rise in the process gas of an air turbine after leaving the turbine, which corresponds to the required preheated combustion air. The clinker is then passed to a further heat exchanger which produces the heat to operate the same air turbine plant. The same process gas flows through the turbo compressor, the first and second heat exchangers, the air turbine and then as preheated combustion air flows into the rotating oven. The heat exchangers are of tubular or box-type design. The hot clinker is transported on a conveyor belt system, which travels through a stationary housing, whose walls are made of tubes. ADVANTAGE - The process reduces the amt. of energy needed per tonne of prod., reduces expenditure of appts. and improves appts. leading to a redn. in pollution levels.

Title: Removal of piece of skin for diagnostic purposes - involves using layer of thin material bonded to skin
Inventor: KALMAR PETER PROF
IPC: A61B10/00
Filed: 1990-10-15
Abstract: A piece of skin is removed from a patient for diagnostic purposes in order to determine the presence of bacteria and to identify any such bacteria.

The base plate consists of two sheets which are sepd. by an insulating layer. The nozzle has a liner and an outer wall which together form a hollow space sealed by a ring. The rubber mixt. in the die adjacent to the lower plate can reach up to 150 deg.C. Water boils at 100 deg.C to cool the lower section and the vapour condenses in the relatively cooler region in contact with the upper plate. The insert including the mouth piece is kept below the vulcanisation temp. so that deposits are avoided. USE/ADVANTAGE - Keeps the temp. below the vulcanisation temp. and prevents premature vulcanisation resulting in contaminating deposits. (0/1)

Title: Heat prodn. by combustion of fuel - by oxidising gas contg. at least 60 per cent oxygen@ produced by filtration of air, and oxygen@ recovered biologically from exhaust gas
Inventor: TISCHMACHER HENRY DIPL ING
IPC: C12M1/00
Filed: 1991-02-22
Abstract: Combustion procedure uses an oxidising gas having an O2 content of at least 60%, and produced in a plant (AO) in which nitrogen is filtered from air. The prods. of combustion, after giving up their usable heat, are taken to a redn. system (BO1) which works on the principle of assimulation by plants, and the O2 recovered from the CO2 content is added to the oxidising gas for the combustion process. The air treatment plant (AO) contains an absorption device (AO1,AO2) in which molecular filters separate N2 from air. The molecular filters allow the passage of mols. with a dia. of less than 3 Angstrom. One of the filters is regenerated under vacuum while the other is in service. Each molecular filter contains a layer in which water vapour and chemically unconverted carbon dioxide are adsorbed. An oxygen buffer container (PO1) is located between the adsorption plant (AO) and the boiler, and the inlet air to the adsorption plant is compressed (VO1) and heat (WTO1). The O2 is further heated by the boiler exhaust gas in a preheater located between the buffer container and the boiler. The redn. system consists of a dark bioreactor and a bright bioreactor. The dark reactor has a gas inlet and a condensate outlet leading via a separator, which removes the hydrocarbons from the water, to the bright reactor. USE/ADVANTAGE - Used in the generation of heat by combustion in power stations, steam raising plant, etc. Allows high efficiency to be achieved by using high combustion temps., while at the same time producing combustion prods. whose content of nitrogen oxides is low. The quantity of carbon dioxide in the exhaust gas is also greatly reduced.
