Patent DE-3713416-A1 (DE)
Inventor: STOBBE ANATOLI
IPC: G01P13/00
Filed: 1987-04-22
Abstract: When a movement acts on them, movement detectors generate electrical signals, and are therefore suitable both for personal protection and for security against intrusion in buildings. 
<??>The new movement detector comprises inside a housing a Hall-effect element with a magnet arranged therebelow, and a freely movable ball situated thereabove, which is made of magnetisable material. Given a change in position of the sphere, there is a change in the flux density of the magnetic lines of force, and as a result a Hall voltage is generated in the Hall-effect element and indicates the movement. Since the movement is detected electronically, a high sensitivity is guaranteed which, in addition, can be set with simple means, depending on the application.

Patent DE-3717288-A1 (DE)
Title: Slide fastener slider
Inventor: NYSTEN BERNHARD DIPL ING
IPC: A44B19/30
Filed: 1987-05-22
Abstract: Slide fastener sliders cannot fulfil decorative functions with their face side because, for technical reasons, space has to be kept free both on the upper plate and on an attachment located there for the free movement of the slider tag. The intention of the invention is not to query the reliability of the slider in a technical sense, but nevertheless to provide it with the possibility of bringing about decorative functions on the garment. For this purpose, a decorative plate is produced, which is separate from the slider body and, when it has been mounted, at least partially covers the face side of the slider body. In this case, the decorative plate is provided with an opening through which a connection member located on the ratchet support projects, while the point of action for the tag located at the free end of said connection member lies above the decorative plate after assembly.
Patent DE-3717313-A1 (DE)
Title: Method for generating and regulating an upwind induced by gravity
Inventor: HAAF WILFRIED DR
IPC: F26B21/12
Filed: 1987-05-22
Abstract: In the ventilation of buildings and the drying of goods, large quantities of air have to be moved. This requires the use of corresponding equipment, such as ventilators and their demand for driving energy. The method allows a regulatable movement of quantities of air by making use of the lift caused by gravity. In transparent building shells, such as greenhouses, by attaching a tower-like elevation or making use of a terrain feature, a pressure difference caused by gravity is generated which induces an upwind. For this purpose, the building shell is sealed against uncontrolled air admissions and inlet and outlet flaps, which are self-regulating or externally controlled, are installed. The self-regulation is achieved by balancing using displaceable weights and by making use of the flow-dynamic lift on curved surfaces. The method allows the transportation of large quantities of air without mechanical driving power. When used in greenhouses for example, it serves for their ventilation during the growing season and for drying products during the summer months. <IMAGE>

Abstract: When spatial movement of points to be measured is measured by means of ultrasonic signals, the problem is that disturbances frequently occur which can lead to a falsification of the measurement results. It is proposed to check the spatial area between the sound transmitter (13) and sound receiver (19) for freedom from obstacles by means of electromagnetic waves, particularly by means of light waves and/or not to use the ultrasonic signals whose transit time and/or amplitude are outside a predetermined expected range, for deriving the distances but to discard these signals.

To this end, there is a protective jacket (2.1) which surrounds the cannula (1) so that it can be pushed back, has a termination part (2.2) on its head and forms part of a transport package in a first protective position (I) surrounding the cannula (1) before use of the injection syringe. The protective jacket (2.1) can be pushed back in the injection position over the shaft of the cannula (1) with exposure of a major part of the cannula, the termination part (2.2) on the head being penetrated by the cannula, and after use of the injection syringe it can be brought back from the pushed-back injection position (III) into a second protective position (II) in which the cannula (1) - which has now been used - is surrounded in a protective manner. The termination part(2.2) on the head side is pierce-proof and it has a cannula guiding channel (4) for pushing-through of the cannula (1). In the second protective position (II) the cannula tip (1a) is trapped between the wall (2.4, 2.5) of the cannula guiding channel (4) and the inner wall of the termination part (2.2). The pierce-proof termination part (2.2), in particular, has a cap or hat shape and is designed with a bottom and a jacket wall (2.4, 2.5) and the cannula guiding channel (4) as an exactly fitting guide pipe (4.1) which extends from the bottom wall (2.4) of the termination part (2.2) into its interior (2.0). <IMAGE>

Title: Comminution machine for thermoplastic refuse
Inventor: MADEISKI THOMAS PETER DIPL ING
IPC: B02C18/18
Filed: 1988-04-25
Abstract: The invention relates to a comminution machine for thermoplastic refuse, in particular for light hollow bodies, also when they are contaminated. The aim and the object of the invention are to develop an arrangement for comminuting thermoplastic containers which prevents radial ejection of the comminuted material into the feed device, so that the installed motor power is truly used only for the comminution and the desired ejection in the direction of the screen takes place. According to the invention, the object is achieved in that an axially arranged screw conveyor, which is connected to a feed funnel and to a cutting device, is provided as a feed device. The material to be comminuted which is continually pressed in through the screw conveyor passes unavoidably into a cutting space arranged directly at the screw-conveyor end, in which cutting space a rotating cutter arrangement is fastened on a driven shaft. <IMAGE>

Title: Independent cylinder control of the ignition/fuel injection in internal combustion engines
Inventor: HAAS JAN THOMAS DIPL ING
IPC: F02D41/00
Filed: 1988-06-28
Abstract: The present invention relates to the following points which are of great interest in the design of engines: The omission of all mechanical parts of the ignition system and the use of electronic components, which are small and light, not subject to wear and also cheaper to manufacture. The achievement of an optimum combustion process, which provides a guarantee of high efficiency and low-emission operation of the engine. The elimination of knocking states and vibrations. In the case of diesel engines where it is difficult to eliminate the mechanics of the injection pumps, the introduction of the injection control described would eliminate the peripheral manifestations such as "diesel knock", and in the design of smaller engines with direct injection of the fuel into the cylinder fewer problems would occur. The engines would be lighter with greater efficiency. With the use of compressors in spark ignition engines or compression-ignition engines, the advantages of the system proposed would come even more to the fore.
