Patent EP-0061706-A1 (EP)
Inventor: BUDDE DIRK
IPC: F01L25/06
Filed: 1982-03-24
Abstract: A double-diaphragm pump having a novel air-pressure reversal device is described, in which there is assigned to a valve controlled piston (52) for reversing the compressed air supplied to the two air chambers (20) of the diaphragm pump a mechanical energy storage device (238) which drives the valve control piston mechanically at the instant of reversal in such a way that even in the case of very slow pump operation the valve is quickly reversed by the stored mechanical energy, so that undefined intermediate positions, possibly accompanied by losses of compressed air, cannot occur. Owing to these measures in conjunction with novel sealing devices (132) for the moving parts, the pressure losses are reduced, and thus the efficiency of the pump is increased, and moreover special lubricating devices are avoided. According to a development, there is provided for the purpose of reversing the compressed air supplied to the two air chambers of the diaphragm pump a pilot valve control device (70) which drives the (main) valve control piston (52) pneumatically in such a way that the main valve is delayed at approximately half the length of stroke, at which position the main valve control piston disconnects the two air chambers both from the compressed air connection and from the exhaust connection, and connects them to one another instead for the purpose of pressure compensation. Owing to these measures, the pressure losses are even further reduced, and the efficiency of a pump thereby increased, and moreover the risk of icing during egress of air is diminished. <IMAGE>

IPC: F02B3/06

Abstract: The process under consideration provides for the treatment of solid municipal waste and waste of other origin without any preliminary crushing so as to obtain a fuel of high calorific power which would be an "alternative" to coal, diesel oil and other costly fuels. For this purpose, the uncrushed solid waste is treated with organic waste, such as sludge, sewage, slaughter offal, manure and agricultural waste, food industry refuse, etc. in order to cause fermentation, which converts the readily biodegradable materials of low calorific power into fertilizer, while the materials that are not readily degradable or not degradable at all and have a high calorific power remain unchanged and can be separated out, for example, by sifting, following removal of the remaining valuable substances, such as glass, metals and plastics.

Abstract: A ceramic shell mold (22) for directional solidification of a single crystal metal article has an improved starter section (26) which converts columnar grain growth to single crystal grain growth. The pitch or lead (L) of the helix is chosen so that the separation between adjacent turns of the helix is less than twice the thickness of the layered ceramic shell material which comprises the mold (22). Thus, when the ceramic shell mold (22) is formed by the repetitive application of layers of ceramic to a wax pattern, the gap between adjacent turns of the helix (20) will be bridged when the mold has reached 50-80% of its final thickness. Then, continued accumulation of ceramic layers bridges the turns of the helix (20) thereby giving it strength. A helical passage diameter in the 8-10 mm range significantly increases single crystal casting yields compared to smaller diameters commonly used heretofore.
