Patent DE-3524849-A1 (DE)
Title: Flowthrough heat pump
IPC: F25B29/00
Filed: 1985-07-12
Abstract: Heat pumps are theoretically suitable for converting relatively large quantities of ambient heat into useful energy. However, as they are too complicated and thus too expensive, the air is to be accumulated in a funnel-like threaded pipe in front of a closure, the latter is to open and close at time intervals and the compression heat is to be removed by the coolant flowing in the additional external thread. Water as heat source is to be swirled together with air therein, then the air is to be separated from the water in the adjacent container and compressed in the second threaded pipe which is built around the smaller first one. The compression is to be forced by the tapering, the narrowing cross-section of the second threaded pipe. The cooling is to take place by the external thread situated on the outside of this second threaded pipe. In this external thread, between the rigid external cover, the coolant is to flow in a counterflowing manner. Between the internal threaded pipe and the external threaded pipe, a heat insulation must be mounted, the device must be mounted in the rigid external cover so as to rotate well and be driven electrically from there.

Title: Process and apparatus for dewatering sludge
Inventor: GILDEMEISTER HANS-H DR
IPC: C02F11/13
Filed: 1985-11-16
Abstract: In the dewatering of sludge, which is pelletised after mechanical pre-dewatering and the pellets are subjected, after encasing with recycled pulverulent materials, to a press-dewatering, considerable quantities of pulverulent materials are required for encasing the pellets, which must be supplied to the pellets as drainage material. This leads not only to a significant increase in the amount of material to be dried, but also in many cases to an undesirable composition of the material to be dried. This is also associated with a not insignificant increase in the total press-dewatered sludge, which also has disadvantageous effects, in particular on landfilling. However, according to the invention these disadvantages are avoided by the recycled pulverulent material used being portions of the dry product alone or in combination with one or more other pulverulent material(s). <IMAGE>

Title: Balance, especially wheel-load balance
Inventor: SCHINDLER ERNST
IPC: G01G23/02
Filed: 1986-03-22
Abstract: The wheel-load balance has a platform (3) which distributes the load to a plurality of elongate hollow elements (2) arranged parallel at equal distances next to one another on a base plate (1). The hollow elements (2) consist of resilient material, and their cavities (12) are filled with fluid. The cavities (12) are connected by means of a connecting line to a measuring member which measures the volume of the fluid displaced out of the cavities (12) under load and which is calibrated in weight units. The cavities (12) of the hollow elements (2) are slit-shaped in cross-section, essentially parallel to the platform (3). The slit width of the hollow elements (2) is dimensioned in such a way that, when the balance is overloaded, the inner faces of the hollow elements (2) limiting the slit (12) butt at least partially against one another before the limit of elasticity of the hollow elements (2) is reached. By the cavities (12) being designed with a slit-shaped cross-section, a plastic deformation of the hollow elements (2) is avoided in a simple way, without bar elements having to be arranged in the cavities. <IMAGE>

Abstract: In the case of a filling machine for filling vessels, especially bottles, with a liquid filling material (liquid) which is under ambient pressure, a plurality of filling elements are provided on a rotor which rotates about a vertical shaft and each have a filling pipe which projects over the underside of the filling element and extends into the vessel to be filled until it nearly reaches the floor of the said vessel during filling. The filling pipe of each filling element is connected to a liquid channel which is formed in the said filling element, is used to feed the liquid to be poured off and contains an electrically controlled liquid valve which is closed in response to an electrical switching signal and interrupts delivery of the liquid into the vessel to be filled when the level of the liquid has reached a predetermined level in the vessel. Furthermore, each filling element has an aeration channel which opens out into the liquid channel downstream of the liquid valve in the direction of flow and can be opened to the atmosphere by means of a controlled aeration valve when the liquid valve has been closed. The aeration valve is controlled by means of a control element in such a way that it only opens the aeration channel when, owing to the relative movement of the filling element with respect to a standing surface which supports the filled vessel, a predetermined volume of the filling pipe is removed from the liquid of the filled vessel and...

Title: Hydraulic free-piston internal combustion engine
Inventor: BEHRENDS ANDREAS
IPC: F01B9/04
Filed: 1986-07-23
Abstract: The invention relates to a hydraulic free-piston internal combustion engine, which can be used to increase the overall efficiency in both fixed and mobile energy conversion systems. The aim of the invention is to essentially improve the overall efficiency of internal combustion engines by reducing the losses incurred in converting linear movement into rotational movement and at the same time to ensure its uncomplicated, compact construction, a low dead weight, the facility for controlling the displacement and improved preconditions for the use of heat-resistant ceramic. The invention achieves this set of objects in that inside a closed cylinder system a gyroscope, designed according to the invention and rotating on a shaft, draws off kinetic energy from a pressurised flowing fluid in such a way that the free pistons supported by the fluid can thereby draw in, compress and exhaust at cyclical intervals. Spheres of application for the internal combustion engine according to the invention are the motor vehicle industry, agricultural and general engineering, the energy industry, shipbuilding, the aircraft industry, military technology, model building and the toy industry.
Patent DE-3639790-A1 (DE)
Title: Method and arrangement for dynamic edge synchronisation of two quasi-synchronous signals
Inventor: SCHIWEK LUTZ-WERNER DIPL ING
IPC: H03K5/135
Filed: 1986-11-21
Abstract: A method for dynamic edge synchronisation of two quasi-synchronous signals is described, the edges of which can temporarily exhibit certain time offset. This is intended for supplying a comparator circuit, followed by a failsafe memory, with synchronous signals. The failsafe memory should only be allowed to drop out when the non-equivalence of two signals exceeds a certain time. According to the invention, the signals are conducted via a two-channel synchronisation stage 1 in which the signal arriving first is in each case switched through directly on its channel and triggers with its edge associated timing elements (MF1 to MF4) which output a defined bridging pulse (TY) on the other channel for switching-on synchronisation, within which the subsequent signal must also have begun on this channel, and that the signal in each case going to zero first of the one channel triggers turn-off timing elements (MF5, MF6), which output a defined bridging pulse (TZ) to this channel for turn-off synchronisation, within which the signal on the other channel must also have gone to zero. The subclaims contain arrangements for carrying out the method. The outlay is advantageously small and, in addition, can be implemented with simpler, non-failsafe technology. <IMAGE>
