Title: Receiving circuit for the amplifiers of the signals captured by the antennas for car radios
Inventor: FERRETTI NERINO
IPC: H03F3/19
Filed: 1988-11-02
Abstract: In the output circuit and the interference filter (100), the feed current of the amplifier (5) of the captured signals of the receiving element (4) is sent through a line (8) which is connected to the centre line (20) of the coaxial cable (3) which forwards the signals from the amplifier to a receiving unit (6). In the output circuit (100), which is earthed by its conductive container (1), a capacitor (10) is mounted on the centre line (20) of the same cable which provides for the forwarding of the amplified antenna signals but which, however, also stops the feed current and does not allow it to reach the receiving unit (6). <IMAGE>

Title: Decentralised, time-dependent room (space) heating control
Inventor: LESSING HELMUT DR
IPC: F24D19/10
Filed: 1989-04-04
Abstract: The method and the construction for time-dependent and decentralised room heating control relate to room heating systems with radiator thermostats as regulating unit in the room or in the dwelling unit. This may apply to radiators installed in an exposed manner, but, for example, also to floor heating systems. The construction can be produced from proven components. The system allows the flexible setting of heating phases, the minimum and maximum temperature for each room or dwelling unit. In addition, permanent room cooling or room warming outside the programmed time phases can be selected. An installation pays for itself within a very short time and can be effected without structural measures in an extremely simple way by replacing the radiator thermostats and fitting the controlling and regulating unit. This applies to new equipment as well as to the retrofitting of old systems. A power supply to the controlling and regulating unit is required. Running costs are insignificant. The savings on primary energy resources are considerable, resulting in significantly reduced energy costs and thus greatly contributing to environmental protection. Moreover, the system raises the quality of life markedly, since the dwelling-room temperatures can be set to individual requirements.
Patent DE-3913011-A1 (DE)
Inventor: ROESSIG STEPHAN
IPC: G06F8/41
Filed: 1989-04-20
Abstract: When programs written for Von Neumann computers are to be used on supercomputers, e.g. vector computers, the operations in the program which can be executed in parallel must be executed in parallel in the vector computers in order to exploit the capacity of the vector computers. These situations can then be introduced into the program if it contains program loops. A program loop which contains no cycles can be vectorized, i.e., executed by vector commands. If a program loop contains cycles, the vector computer must contain special commands for executing these cycles in parallel. A special command of this type can, for example, be a command for forming the vector sum or for forming an arithmetic series. The command loops are inspected for the presence of cycles which can be replaced by these special commands. To this end, the control flow and data flow determined by the commands in the loop are inspected and control dependencies and data dependencies between the scalar presence of variables in the commands are determined and plotted on a graph. This graph is then thoroughly analysed to determine whether any cycle it contains can be replaced by a vector command of the vector computer.

Title: Composition for fertilisation, soil improvement and protection of waterways
Inventor: BANNWARTH HORST PROF DR
IPC: C02F1/66
Filed: 1989-07-03
Abstract: In order to produce suitable cultivation areas and conditions for plant growth in all regions, to avoid and eliminate environmental damage and damage to industrially exploited ground, and also in particular to combat new kinds of damage to forests, it is proposed to employ mixtures ("stabilisates") comprising basic components such as brown coal (lignite) ash and gypsum, especially from flue-gas desulphurisation plants (FGD gypsum). The intention of the invention is in general to increase yields, to provide better utilisation of fertilisers, to improve the soil and to protect waterways. It can be used to benefit the goals of protecting nature and the environment in that recyclable residues having a positive effect on ecosystems are used (recycling), saving on natural resources while at the same time reducing the problems of landfill disposal of residues from power stations. The idea of the invention consists in combining basic substances, such as ash, with gypsum - and if desired additives - for the stated purpose in such a way that disadvantages of the individual components are removed. The agent contains harmless residues from brown-coal combustion and flue-gas cleaning. It is an environmentally friendly product.

Patent DE-3936812-A1 (DE)
Inventor: HEINDL RICHARD
IPC: F04B1/20
Filed: 1989-11-04
Abstract: In inclined-shaft axial piston machines a drive shaft and a cylinder drum are functionally interconnected via a synchronising shaft with terminal universal joints to obtain the most uniform rotation speed possible. The synchronising shaft is given its necessary axial fixation via spherical surfaces integral with the synchronising shaft which bear with a pre-stress on plane surfaces integral with the drive shaft and cylinder drum. Owing to a striking movement communicated to the synchronising shaft by the universal joints during operation and the resultant "hammer", known machines are subject to considerable wear at these supporting points. In order to reduce this wear at least substantially, spherical calottes (18, 21) are provided to transmit the pre-stress which bear radially and with the ability to slide via plane end surfaces on the plane frontal surfaces of the synchronising shaft (17), and their spherical surfaces are borne in spherical dishes of two pressure members (19, 20) fitted concentrically with the drive shaft (4) and the cylinder drum (5).

Patent DE-4024759-A1 (DE)
Inventor: ZEISE CHRISTIANE DR
IPC: C11D3/395
Filed: 1990-08-03
Abstract: Described is a free-running granular material whose main component is finely particulate bleach activators for textile laundering and a substantially water-free binder phase consisting mainly of solid material. This binder phase is a homogenized mixture of surfactants, at least a proportion of the components of the mixture being fluid or at least plastic at the granule-formation temperature and the composition of the mixture being selected so that the binder phase softens to become fluid or plastic, without the need to add water, at the granule-formation temperature. The granular bleach activators can be produced by mixing the finely divided bleach activators with the surfactant components, homogenizing the resulting mixture at preferably only moderately elevated temperatures to give an extrudable compound and extruding using high pressure, the extruded strands being cut into the required grain-shape lengths and optionally rounded, under process conditions which avoid sticking of the freshly extruded material.

Patent DE-4034511-A1 (DE)
Title: Aircraft propeller with two blades mounted one above other - with gap between blades functioning as nozzle
Inventor: WERDING HANS J
IPC: B64C11/24
Filed: 1990-10-30
Abstract: The aircraft propeller has two blades of aerofoil section mounted one above the other so that a nozzle like gap is formed between them. The increase in the velocity of the air flowing between the blades causes a reduction in pressure which fades out in the region of the leading edges. This reduction in pressure further increases air velocity, reducing the resistance and providing increased driving force. The increased efficiency of the propeller enables it to be operated at a lower rotational speed with a consequent reduction in the gyroscope effect. The principle can be applied to the rotor of a helicopter where the reduction of the gyroscope effect enables the helicopter to be more easily controlled. ADVANTAGE - Propeller of increased efficiency which can operate at a lower speed with consequent decrease of the gyroscope effect.
