Title: Securing structure for steep slopes and walls in which vegetation can grow
IPC: E01F8/02
Filed: 1981-02-05
Abstract: The invention relates to a securing structure for steep slopes and walls, in which vegetation can grow, at traffic routes, consisting of precast concrete parts arranged in a row and stacked one on top of the other. According to the invention, the individual precast concrete parts in each case consist of an open frame with a longitudinal member and at least two cross members which are connected to the longitudinal member and are arranged approximately perpendicularly to the axis of the longitudinal member and the overall height of which is roughly as large as that of the longitudinal member. The precast concrete parts are stacked one on top of the other in such a way as to be alternately turned horizontally through 180 DEG  relative to one another so that they form a closed frame in pairs. As the drawing shows, the alternate stacking of the parts one on top of the other results in spaces (12) between the parts, in which spaces (12) vegetation can grow. In this arrangement, the longitudinal members serve to support the earth. The top and bottom sides of the transverse members form bearing surfaces during the stacking. <IMAGE>

Title: Power plant utilizing environmental heat
Inventor: BEHNEMANN WILHELM
IPC: F25B9/00
Filed: 1981-04-24
Abstract: The function of the power plant utilizing environmental heat is to extract heat from groundwater, lakes, the sun, a heat fence or the air, to convert it into mechanical energy and thus to drive a compressor (heat pump). Refrigerants such as carbon dioxide and Frigen 22 are used here as energy carriers. The carbon dioxide is heated at 20 DEG C in the evaporator (6) by supplying a heat carrier (10), and in the process the pressure rises to 60 bars. The gaseous carbon dioxide flows through a turbine or reciprocating engine (1) and condenses in the condenser (7) at 0 DEG C = 36 bars. The energy released by the pressure drop is transmitted via the mechanism (2) to the compressor (3). The carbon dioxide arriving in the condenser is pressurised in the evaporator (6) by the feed pump (5). The compressor (3) with the condenser (8), which belongs to the circuit, and preheater (9) and controller (4) operate as a heat pump and are filled with Frigen 22. The controller is, however, fitted to the condenser (7). The evaporated Frigen 22 extracts the heat from the carbon dioxide in the condenser (7) down to 0 DEG C and maintains the required temperature in the preheater (9). The condenser (8) serves as a heat exchanger; heat released is passed to the consumer. <IMAGE>

Patent DE-3126417-A1 (DE)
Title: Hydraulic change-over device for a reversible plough
Inventor: BRANDENBURGER WALTER ING GRAD
IPC: A01B3/421
Filed: 1981-07-04
Abstract: The invention relates to a hydraulic change-over device for a reversible plough with a double-acting piston/cylinder unit and a reversing device which switches in a pressure-dependent manner and effects an automatic double stroke. The risk existing in reversing devices which switch in a pressure-dependent manner, namely the risk of a premature switching by means of pressure surges upon starting-up or steep pressure increases in the vicinity of kinematic dead-centre positions, is substantially avoided by means of the incorporation of a valve member in the admission. The valve member consists of a spring-loaded actuating piston with two active surfaces which are directed towards one another, of which the one directed towards the spring is loaded permanently by the admission pressure and the other is loaded by the respective pressure in each working chamber, which is connected to the admission in the first stroke phase. The valve member therefore acts, in the first stroke phase, as a differential pressure regulator which closes in the event of a small pressure gradient. In the second stroke phase it opens even in the event of comparatively small pressures in the admission, since no pressure is exerted on the other active surface.
