Title: Composting domestic refuse and other waste matter - by preliminary disintegration and the gradual building of layered heaps
Inventor: SPOHN EBERHARD DR
IPC: C05F17/00
Filed: 1975-08-29
Abstract: Materials capable of being rotted down are converted to compost in a heap; the raw material being prepared by reducing the hard substances such as glass, stone, bones, hard plastics, etc. to a granular size of 1 mm, and the soft material to a size of 10 mm at most, so that further sieving is unnecessary. The material is laid on to the side surface of the heap in shallow strips, whilst thin layers are brought from the old side, mixed, brought to the normal optimal moisture content and laid in strips on the heap afresh. When finely dispersed matter such as sedimented sludge is used this is first of all pelletised to a preferred size of 10 mm. Overcomes the problems of the development of anaerobic zones in the heap, and difficulties of sieving material with too high a moisture content. There is no problem of disposing of materials which fail to pass the sieves. The finer preparation of the material results in an intensification of the rotting process, and to an explosive increase of the micro-organisms concerned. This causes additional heat to be developed which effectively vapourises the water content so that rain or snow conditions do not cause excessive humidity.

Title: Pressure vessel for storing fluids - has walls formed from a series of curved elements welded together
Inventor: JOOS ERHARD ING GRAD
IPC: B65D90/02
Filed: 1975-12-05
Abstract: Press. vessel for storage of liquids and gases is of rectangular form with each wall constricted from a series of curved elements welded together along their edges. The axes of the elements in adjoining walls are rotated at 90 degrees to each other. The sides with the vertical profiles have flat edges to which the curved ends of the horizontally profiled sides are welded. Similarly the horizontal sides have a flat upper edge to which the curved profile of the lid is welded. This in turn has flat edges to which are welded the upper edges of the vertical profiles. The vessel has a flat base plate with T-shaped cross members. Tie rods run from these to the edges of the profiles in the lid. Vessel can be used in the storage under pressure of liqs. and gases. Although rectangular tanks represent a considerably saving in space compared with cylindrical or barrel shaped tanks, they are in many instances uneconomic because of the metal thickness required to withstand the internal pressure. This design allows the space advantage of rectangular vessels to be largely retained only using much light (and therefore cheaper) gauge plate.
