Patent DE-3027319-A1 (DE)
Inventor: KRUEGER ECKHARD PROF DR ING
IPC: C12C1/18
Filed: 1980-07-18
Abstract: The process for the preparation of a low-carbohydrate, alcohol-reduced and low-calorie beer in which the wort is fermented in such a way that the fermentable carbohydrates and the dextrins, which can be fermented only with difficulty and which are converted into fermentable carbohydrates by addition of diastase solution, have been fermented until there is at least 0.75 g of carbohydrate per 100 ml of beer, and the alcohol content of the beer is reduced under reduced pressure. In order to be able to brew an improved quality of low-carbohydrate, alcohol-reduced and thus low-calorie beer in a continuous and thus simplified process, the alcohol reduction is carried out in a thin-film evaporator at a temperature of about 50 DEG C, preferably 30 DEG C, and for a short time of between 1 and 10 seconds, and the alcohol reduction is carried out in the bypass during the main fermentation.

Title: Blueing of ferrous metal workpieces - which are first coated with water repellent oil and heated before being exposed to steam which forms ferrosoferric oxide coating
Inventor: STARCK AXEL VON DR ING
IPC: C23C8/18
Filed: 1980-07-26
Abstract: The workpieces are first coated with a water-repellent and volatile material, pref. an oil, and are then fed into the first chamber of a continuous furnace. In the first chamber, the workpieces are heated in a current of air to above the temp. of rust formation (i.e. above the dew point), and also to volatilise the oil. The workpieces next travel into a second furnace chamber contg. hot steam, so a coating of Fe3O4 forms on the surface of the workpieces. The amt. of air flowing through the first chamber is pref. adjusted so a non-explosive or non-combustible atmos. is formed in this chamber. Useful for the blueing of electrical steel laminations or other pieces which are machined or partly machined. The use of batch type furnaces involving long and expensive processes can be eliminated.

Patent DE-3039470-A1 (DE)
Title: Energy from colliery waste heaps - by passing through shaft furnace, and roll crushers to fluidised bed furnace
Inventor: HOELTER HEINZ DIPL ING
IPC: F23K1/00
Filed: 1980-10-18
Abstract: Waste from dump heaps of collieries containing 20% of coal substance is often so hard that crushing or grinding operations are not justified. This can be remedied by passing the waste first through a shaft furnace in which a low- temperature carbonisation process makes the waste so friable that roll crushers can readily complete the comminution process to under 20 mm particle size. The waste then can be used as a fuel for fluidised bed furnaces where the bulk of its energy is utilised.

Title: Pile driver
Inventor: HERBOLD WOLFGANG DR ING
IPC: E02D11/00
Filed: 1981-09-26
Abstract: Hitherto known pile drivers for driving in and out have a definite, fixed expansion ratio and strike only in one direction. To change the driving direction, they have to be removed from the object to be driven, turned around and attached again. In addition, the transfer of the pressure medium in them from one pressure chamber to the other takes place via grooves between the striking body and the inner part so that there are long control edges and short sealing surfaces. Control pins (26, 30) are now used for controlling the admission of pressure medium. The control pins (26, 30) lie in the annular piston (11) of the striking body (10) and are longitudinally displaceable relative to the annular piston (11). They are either fixed longitudinally - during expansion drive - or are limited in their longitudinal movement - during filling control - by the flanges (4, 5) of the inner part (6). In addition, connections can be provided between the pressure chambers and the air vessels. The wear is reduced and a smooth-running capability is produced. Several control pins of different function can be provided at the same time in one pile driver. Control pins which are not used are rendered inoperative by closing the inlet and outlet passages. <IMAGE>
