Patent DE-2707799-A1 (DE)
Inventor: MEIER-SCHENK ARTHUR
IPC: F16L1/028
Filed: 1977-02-23
Abstract: In the case of long-distance lines being laid directly in the ground for hot or cooled, fluid or gaseous heat media, insulating pipe sections are laid in a dug-out trench and are connected to one another in a sealing manner there at their ends. The insulating pipe sections consist of an inner heat-medium pipe and of an outer protective jacket pipe. An insulating jacket is foamed into the intermediate space, which insulating jacket produces a force-fitting bond between the two pipes. In consequence, expansion forces of the heat-medium pipe are transmitted uniformly to the exterior via the insulating jacket and the outer jacket pipe, over the entire length, and, in a reverse manner, the friction forces between the earth and the jacket pipe are likewise transmitted uniformly inwards to the heat-medium pipe over the entire line length. In consequence, lines of any desired length can be laid without any fixing points.

Title: Rectangular vessel for boiling beer wort - has heated base sloped up to central longitudinal ridge to improve wort circulation
Inventor: WOLFSEDER ALFONS
IPC: C12C13/02
Filed: 1977-06-07
Abstract: A beer wort boiling vessel of rectangular, horizontal cross-section. The vessel is of the type having a sloping base which can be heated to raise the temp. of the vessel's contents. The base of the vessel rises between the vessel sides in the form of a single ridge roof with its apex running parallel to, and pref. centrally between, the two longitudinal sides of the vessel. Pref. each end of the ridge does not reach the end wall of the vessel; instead it is joined to the bottom edge of the end wall by an inclined surface set at a slope which is steeper than the longitudinal sides of the ridge. The side slopes of the ridge are pref. symmetrical about the longitudinal centre-line of the tank. Each side slope pref. has a lower section at 10-20 degrees to the horizontal blending into an upper section at 10-20 degrees to the horizontal. Pref. all round the raised area of the base, a drain gully is formed at the lower edge of the end and side walls. The heated slopes to a central ridge of the base give rise to a convective circulation of the wort which tends to rise like a fountain above the ridge. This produces highly efficient heat transfer, improved coagulation and vaporisation. Additional heating surface is provided by the sloping up to the ridge.
