Title: Simple means of raising height of dam - comprises flexible e.g. PVC tubing of suitable dia., filled with water and laid on top of dam, so that its friction prevents rolling
Inventor: DOERPINGHAUS ERNST H DIPL ING
IPC: E02B7/16
Filed: 1991-01-15
Abstract: A device to raise the height of the top of a dike to prevent flooding or to confine and divert overflow consists of a tube of flexible plastic material; this is filled with water so that its wt. and friction at the bottom prevent the dammed liq. from spreading. The tube is pref. made of a thermoplastic or elastomer with or without fabric reinforcement. In an example, the tubing (1) is placed on the dike (5). Its wall thickness is say 1 mm and it made of e.g. PVC with or without a fabric reinforcement. Its dia. is greater than the (2) required depth of floodwater (4), so that its weight and friction prevent its movement by the floodwater (4). The grip on the dike (5) can be heightened further by bonding the tubing (1) to a plastic strip (6) which is itself held in position by e.g. pegs (7). If a second filled tube is also placed next to the first the combined grip on the dike top is considerably enhanced. USE/ADVANTAGE - The prod. can be used for dams or tanks and can be applied very quickly. It functions simply and rapidly by virtue of the universal availability of water for filling it. Its height is constant along its length.

Filed: 1991-07-05
Abstract: Registering programme control parameters for household washing machines using revolution speed electronics a reversibly driven drum, a water supply system regulated irrespective of operational pressure, and a level control system. At the start of the programme and when the drum is stationary and has been loaded, the time span (t1) until the working level (NA) has been reached for the first time is measured. After the reaching of the working level (Na), the first laundry absorption time (tS1) until the level is lowered to the reconnection level (NE) is measured. For the now reversing drum, the process involves measuring the directly succeeding second absorption time (tS2). Temporal difference between the second and the first times (tS2-tS1) is determined. Number of all replenishing processes from the reconnection level to the working level are registered. ADVANTAGE - Machine automatically determines whether a programme is required for small or large volumes of washing while taking into account the type of washing.
