Patent DE-3513264-A1 (DE)
Title: Gas-blast circuit breaker
Inventor: ISCHI JUERG
IPC: H01H3/46
Filed: 1985-04-13
Abstract: The gas-blast circuit breaker which is preferably provided for switching medium voltages has in each case two erosion contacts (8, 10) and rated-current contacts (7, 9) which are located in a housing (1) filled with insulating gas and interact with one another. In order to achieve a compact construction, current connections (5, 6) are passed to the interior of the housing (1) transversely with respect to the movement direction of a moving erosion contact (8) of the two erosion contacts (8, 10). In the case of this gas-blast circuit breaker, it is intended to keep the drive energy required for a switching process as low as possible, while maintaining the compact construction. This is achieved in that the moved rated-current contact (7) is supported such that it can rotate, and in that a drive which acts on the moving erosion contact (8) and on the moving rated-current contact (7) has two insulating material rods (17, 18) which are articulated on a drive crank (20), and one of which is articulated on the moving erosion contact (8) and the other on the moving rated-current contact (7). At the same time, the two insulating rods (17, 18) are articulated on the drive crank (20) in such a manner that, a thrust crank, which is formed by the drive crank (20), the one insulating material rod (17) and the moving erosion contact (8) passes through a dead point (21) before reaching the switched-off state. <IMAGE>

Patent DE-3531570-A1 (DE)
IPC: F02B19/12
Filed: 1985-09-04
Abstract: An ignition device (4) is disclosed for internal combustion engines comprising a precombustion chamber (7) near the spark plug (5) and a connection (8) serving as a throttle (9) between the precombustion chamber and combustion chamber (6) of the engine. The purpose of the invention is to provide an ignition device which allows the use of normal spark plugs with only minimal structural modifications. To achieve this, the throttle line (8) is at least as long as the distance (14) between the ignition electrode and the start of the throttle line. It is thus possible to use inexpensive spark plugs which are mass-produced. Flowing through several gas lines, the mixture reaches the central electrode of the plug; or a large duct becomes narrow in the region of the central electrode and in the outflow direction a high speed is achieved in the direction of flow by the Laval nozzle effect, with the result that the ignited gas leads to quick and complete combustion of the main gas mixture.

Patent DE-3611867-A1 (DE)
Title: Apparatus for determining the flow properties of flowable substances (suspensions and fluids)
Inventor: WINDHAB URSULA
IPC: G01N11/06
Filed: 1986-04-09
Abstract: The invention relates to a measuring apparatus for determining the rheological properties of flowable substances, in particular including suspensions such as are encountered in food and pharmaceutical industries, in the plastics and dye industries and in the ceramic industry, as well as in crude oil production (recovery). The flow behaviour and the wall slip behaviour of the substances can be quantified from the inflow behaviour of the suspensions flowing into a vertically arranged measuring capillary into which the substance to be investigated is pressed by virtue of the hydrostatic pressure of the substance in the storage vessel, or by means of external pressure. The flow behaviour describes the internal flow, and the slip behaviour the slippage at the bounding walls. In addition, this apparatus is the first to permit a simple direct measurement of the flow limit (= critical shear stress for the start of internal flow) and the slippage limits (= critical shear flow for the start of wall slip). In the special embodiment of the measuring apparatus as a measurement probe, the flow behaviour can be measured directly in appropriate containers. Processing methods can be designed with the aid of the rheological characteristics to be measured using this apparatus.
