Patent DE-3226693-A1 (DE)
Title: Control valve which can be optimised in relation to water hammer
Inventor: KELLNER ALBRECHT DIPL PHYS DR
IPC: F16K47/02
Filed: 1982-07-16
Abstract: The invention discloses a valve for the arbitrary closure of a pipe through which a fluid can flow, which has a closing function favourable for the reduction of water hammer. In a preferred embodiment, a bilinear closing function which approximates the optimum closing function is implemented mechanically. For this purpose, the insertion mechanism for the closure member (4) and/or the flow duct have means which influence the closing function in an appropriate manner. Such a closing function can be achieved by means of an insertion mechanism which comprises telescopic sections (6, 8 and 10, 11). At the beginning of the closing operation, a spring (9) under prestress is released via a release mechanism (12) and moves the closure member first of all very rapidly into the path of flow. After coming up against a stop (15), the closure member (4) is moved further at the driving speed of the upper part (11) of the driving rod. In this way it is possible to achieve a bilinear closing function. By adjusting the stop (15) and changing the spring constants and/or prestress of the spring (9) and by selecting an appropriate driving speed for the driving rod (11), the parameters of the closing function can be adapted to various pipe systems. <IMAGE>

Abstract: The present invention relates to a process for the production of N-substituted acrylic acid amides by conversion of 2-carboalkoxy-t-oxabicyclo(2,2,1)hept-5-enes with primary or secondary amines to 2-carboxamide-7-oxabicyclo(2,2,1)hept-5-enes and the thermal decomposition of the latter, preferably in the presence of Lewis acids and in a vacuum, to furane and N-substituted acrylic acid amides. The process according to the invention results in high purity N-substituted acrylic acid amides that are, in the main, free of bifunctional monomers which would disrupt the subsequent polymerization of the N-substituted acrylic acid amides by undesired cross-linking.

Inventor: FAUSTKA HELMUT
IPC: B23B51/04
Filed: 1983-02-23
Abstract: Drilling tool comprising a tool shaft with at least one flute and an interchangeable cutting element. The cutting element is comprised of one or two cutting flute plates having each a main cutting edge. On the narrow side of the plate, facing the bit, there is provided a fixing trunnion concentrically with respect to the bit axis and having two mounting surfaces. The tool shaft has at its point in the wall of the flutes a flat hollow for the cutting plates and, at the middle, in a concentric position with respect to the bit axis, a housing for the fixing trunnion with lateral surfaces for the assembly. The cutting element is inserted from the top, rotated at about 45<o> towards the rear wall of the hollow, into the shaft point and secured by a rotation in the drilling rotation direction. During the drilling, it is supported against the cutting efforts by the back wall of the hollow and its edge facing the shaft. The fixing trunnion maintains the cutting elements in a concentric position. Thereby the cutting element is biased by the cutting efforts into its seat and is secured therein without requiring additional securing devices such as screws. The configuration of the fixing trunnion may be conical, cylindrical or as a dovetail.
