Patent DE-3312123-A1 (DE)
Title: Proportional valve
Inventor: MOESER MANFRED ING GRAD
IPC: F16K11/07
Filed: 1983-04-02
Abstract: A proportional valve with flow passages formed in its valve housing and influenced by a piston displaceable in the valve housing is to be developed in such a way that, at an increased useful stroke of the piston, the wear phenomena are to be reduced in such a way that long service life of the valve is achieved even when water, for example, is used as the controlled pressure medium, and the dependence of the flow through the controlled passage as a function of the piston stroke can easily be established during manufacture. This is achieved by the piston being displaceable in two equiaxial tubes whose end faces, facing one another and guided at an angle with an axial component, enclose a gap having at least one axial component. The gap is designed in such a way that the stroke of the free end face of the piston corresponds to its axial extent, and the gap is enclosed by an annular space which receives the fluid passing it.

Title: Inclined rear window for motor vehicles
Inventor: STEGE JUERGEN DIPL ING
IPC: B60J1/18
Filed: 1983-04-13
Abstract: An inclined rear window for motor vehicles is proposed which has two windows extending at a distance from one another and having a laminas arranged between them for reducing the entry of the sun's rays. The laminas are arranged in such a way that a flow of air is possible between openings which are arranged offset from one another and which connect the space between the windows to the passenger compartment on the one hand and to the external air on the other. Preferably, some of the openings are made in the upper edge region of the inner window and the other openings are made in the lower edge region of the external window and the laminas on the insides of the two windows are arranged offset with respect to one another in order to form a labyrinth-like air guiding system. The proposed rear window thus permits effective ventilation of the passenger compartment, counteracts misting up of the rear window and reduces the entry of the sun's rays when the outer contour of the rear window is of a flat design.

Title: Buckets for high-output bucket conveyors
Inventor: KOSTER KARL H DR ING
IPC: B65G17/36
Filed: 1983-06-24
Abstract: A bucket for bucket conveyors, especially for high-output bucket conveyors, has an outside wall (2) which is divided into an upper section (b) and a lower section (a). The upper section (b) approximately matches a logarithmic spiral and, together with the inside wall (1) forms an angle of aperture ( epsilon 2) which is smaller than the angle of aperture ( epsilon 1) which the lower section (a) forms with the inside wall (1). Complete emptying of the bucket by means of centrifugal force even at high conveying speeds is achieved in this way. A covering plate (7) which partially closes off the aperture (6) of the bucket stops any of the loose material from being jolted back out of the bucket at high conveying speeds while the bucket is being filled. <IMAGE>

Title: Permanent lining of formwork elements
Inventor: PFANNENSTIEL PHILIPP-KASPAR DI
IPC: E21D11/08
Filed: 1983-08-31
Abstract: Formwork at the same time serving as permanent lining can be created from individual panels of identical design, which formwork is subsequently completed with backfill concrete to form early-bearing concrete lining. In this arrangement, the panels are connected to one another in a tension-proof and compression-proof manner by hollow lugs which can be inserted into recesses in the panels, so that there is the requisite sealing relative to the backfill concrete to be poured in later. In addition, these connecting points can also serve or be used in an advantageous manner to place anchor bars in order to thus create effective composite permanent lining. <IMAGE>

Patent DE-3417734-A1 (DE)
Title: Method and device for continuously determining the quality of fuel gas
Inventor: KUHN PETER DIPL ING
IPC: G01N33/00
Filed: 1984-05-12
Abstract: The invention relates to a method and a device for continuously determining the quality of fuel gas. Whereas known devices are expensive to build and maintain, the advantageous invention is intended to provide a very simply producable measuring device which functions in a maintenance-free fashion even in the case of a relatively long operating time. For this purpose, the invention employs acoustic properties which change in sympathy with changing gas quality by making use of the resonance frequency of a resonating system for the purpose of identification. This is performed by using a partial current to generate oscillations in the resonance system, the frequency then experiencing an electroacoustic conversion. Use is made of a resonance tube and a sensor for mechanical vibrations, which sensor generates via a frequency-measuring instrument a signal which corresponds to the gas quality and can be utilised to control a gas pressure governor, for example.

Title: Automatic test device for data capture devices and electric wiring for aircraft
Inventor: UECK MARTIN
IPC: G01R31/00
Filed: 1984-10-12
Abstract: Until now, monitoring any data capture device directly where it is used was only possible by using very large test instruments and by specially trained measuring instrument engineers, that is specialists, spending a long time. In most cases, the result of removing a data capture device from its direct area of use for monitoring in a workshop was that the control and verification devices, which the device was supposed to capture data from, completely failed to function. Both so that the data capture devices (11) can be monitored directly at the place of use in realistic operating conditions, and so that the monitoring can be done by untrained operating personnel, so that even complex testing of the data capture devices (11) is possible, the invention proposes an automatic test device (10), in which an externally controllable measurement data capture system (12) is used, in conjunction with an operating unit (15), which has, at least, an input keyboard (16), a display device (17), and a printing device (18), and is connected to a computer (14), forming a control unit (13), which is connected via a line (19) to the externally controllable measurement data capture system (12) and the data capture device (11) to be tested. <IMAGE>
