Patent DE-3047936-A1 (DE)
Inventor: LELY CORNELIS VAN DER
IPC: A01B13/00
Filed: 1980-12-19
Abstract: In a plough of the kind which comprises a mobile frame (1, 2) and at least one plough member (15A) that will wholly or partly invert a furrow slice when the plough is in operation, said furrow slice is cut loose by a V-shaped blade (18) located at the front of the frame (1, 2) with respect to the intended direction of operative travel (A) of the plough and is both compressed, and deflected laterally towards one side wall (2) of the frame (1, 2) by a plurality of rotary lateral displacing members (4, 5, 6, 7, 8) that are in the form of rollers arranged in a row that is inclined to said direction of travel (A), the members/rollers (4, 5, 6, 7, 8) being of progressively increasing size considered rearwardly of the direction of travel (A). The lateral displacing members/rollers (4, 5, 6, 7, 8) co-operate with a soil guide member (15) at the rear of the plough in turning the cut furrow slice about an axis which extends in the direction of operative travel (A) to enable said furrow slice to be deposited substantially completely back into the furrow from which it was originally cut in a substantially completely inverted condition as compared with its original position. In a modification, the number of lateral displacing members/rollers is reduced and the guide member (15) in the form of a fixed plate is replaced by a power-driven rotary soil guide member of annular formation, the inverted furrow slice being delivered back into the furrow from which it was cut through the interior of said annular guide member.

Title: Device for connecting movable loading ramps to vehicle frames
Inventor: KURZ HUBERT PROF DR ING
IPC: B60P1/04
Filed: 1981-05-04
Abstract: The invention relates to a device for connecting loading ramps to vehicle frames, which device releasably connects the loading ramp, which has been raised or lowered essentially perpendicularly to the level of the vehicle frame by swinging arms, to the vehicle frame. For this purpose, supports (4a and 4b), and if required (4c), which receive load-bearing elements of the loading ramp, are arranged on the insides of the vehicle frame. The locking movement is brought about by switches which can be swivelled into the perpendicular guide tracks and by their oblique planes impose a horizontal component of motion on the loading ramp. The support (4d) which is arranged in the central region of the loading ramp permits the loading ramp to tilt once the tilting bearing (9) has been swung in. <IMAGE>

Title: Adjusting device for driving discs in rod drivers
Inventor: NICOLAI EBERHARD
IPC: B21B31/28
Filed: 1981-07-29
Abstract: The invention relates to an adjusting device for driving discs in rod drivers (pinch roll units) for rolled stock moving at high speed, having driving discs mounted in rockers which have partial toothing engaging in a worm arranged vertically in the driver housing and having both right-handed and left-handed toothing. The aim of the invention is as far as possible to eliminate the disadvantages caused by inaccurate setting of the driving discs, such as a reduction in the life of the driver and the risk of a break-down due to a back-up of the rod. It is thus the object of the invention to allow optimum setting of the nip and to ensure that the optimum setting of the driving discs is maintained when these have worn. According to the invention, the object is achieved by virtue of the fact that a spring-loaded tappet (7) arranged on the end face of the upper worm (5) is connected to a gear pair (8) and a contact lever (9) arranged on this gear pair and having a switching contact (10) or that, instead of the tappet (7), a switching disc (16) is provided and associated directly with this disc is a proximity switch (18) lying in the same plane. The invention is used in rod rolling mills. <IMAGE>

Title: Circuit arrangement for measuring and displaying the quantity of heat dissipated by a heater (radiator)
Inventor: HENNEBERGER HEINZ DIPL ING
IPC: G01K17/08
Filed: 1981-08-01
Abstract: In a heating cost distributor which is intended to measure and display the quantity of heat dissipated by a heater and of which a high operational reliability, security of manipulation and accuracy of display are required, a circuit arrangement is proposed which has a first frequency generator (3) which converts the output signals supplied by the heater temperature sensor (1) into a frequency proportional to the heater temperature. Said frequency is allocated to a microprocessor (4). The circuit arrangement feeds an output variable, supplied by the temperature sensor (1), to the microprocessor (4) together with a factor which is proportional to the heat-dissipating area of the heater. Connected downstream of the microprocessor (4) is a pulse counter (5) which drives a display circuit (7) via a decoder circuit (6). A heating cost distributor connected in this way can easily be mounted on a particular heater. It is possible to take account of all the factors required for displaying the share of the quantity of heat which is dissipated. In accordance with a development, a room temperature sensor (11) is also provided, its output signal being fed to a second frequency generator (13), which is connected to the microprocessor (4) and whose output frequency is substracted from the output frequency of the first frequency generator (3) in the microprocessor (4) and further processed. All the switching stages of the evaluation circuit are arranged in a common housing which can be mounted on a heater. <IMAGE>

Title: Method of identifying mines after expiry of a predetermined time
Inventor: MENNE ROLF
IPC: F42B23/24
Filed: 1981-10-07
Abstract: The present invention relates to a procedure for making it possible to locate laid mines which are invisible, in order then to pick them up and provide them for renewed reuse. However, it should not be possible to locate the mine during its predetermined active time. In the solution for achieving the given object, a magnet, the field of which is screened, is arranged in or on the mine. This screening is effective during the active time of the mine. It consists, for example, of a bar of soft iron or ferro-ceramic which connects the poles of the magnet and which bears closely against the magnet. After the expiry of the active time of the mine, the screening material is separated from the magnet by means of sensors, if appropriate by the agency of a pyrotechnic composition, so that its field can propagate. This field can consequently be located by means of known detectors and the exact position of the mine therefore determined.
Patent DE-3140672-A1 (DE)
Inventor: REBHAN DIETER ING GRAD
IPC: E02D19/14
Filed: 1981-10-13
Abstract: Tunnels are constructed by freezing soil and removing frozen soil between starting and end shafts of the tunnels. Tunnels are driven in an uncomplicated manner in rapidly changing soils without auxiliary construction means. A hole is bored in or near the planned axis of the intended tunnel between starting and end shafts. A soil freezing work pipe is inserted into the hole. The pipe is cooled by a cooling agent. The soil freezing work pipe continues to be cooled until an ice and frozen soil mass has formed around the work pipe, which frozen mass has a diameter which is larger than that of the planned tunnel. Frozen soil is subsequently excavated, leaving a frozen soil lining, which is immediately supported by a primary support lining or a permanent lining.

Title: Arresting arrangement for a combined overrun and parking brake system for trailers
Inventor: URBANKE WALTER DIPL ING
IPC: B60T7/20
Filed: 1982-04-16
Abstract: The arresting arrangement according to the invention can be used for a combined overrun and parking brake system, operable in parallel, for trailers with automatic reverse in the wheel brake. At the same time the parking brake system has a greater operating travel than the overrun brake system. The aim of the invention is to simplify the adjustment of brake systems of this type without using any special devices. An adjusting arrangement for the point of application of the brake of the overrun system is thus to be created in order to be able to adjust the brake system. According to the invention a locking disc of a type known in the art for the parking brake has only a single notch in the operating range of the overrun brake system, the position of which notch corresponds to the start of the overrun braking process, notches for arresting of the parking brake being arranged only in an area after the end of the overrun distance and/or the operating range of the automatic reverse. <IMAGE>

Patent DE-3227522-A1 (DE)
IPC: H02J7/04
Filed: 1982-07-23
Abstract: Method and device for monitoring the each time-charged capacity of accumulators comprised of cadmium-nickel cells, during a rapid charge in a plurality of phases, from an unknown charge status. According to the invention, during the first charge phase, a charge current which is multiple of the charge current I10 given by the manufacturer is supplied until a preset switching voltage is obtained. At the switching, a second charge phase follows with a much weaker charge current during a given period of time at the end of which the charge process is stopped if it has not been stopped before because a certain limit voltage or a predetermined temperature has been exceeded. The charge time and the limit voltage are selected so that, during the total time period, only the accumulators having a sufficient capacity are charged, the charging process of the other accumulators being interrupted earlier because the limit voltage, respectively the limit temperature, has been reached.

Title: Control device for a fuel metering system of a diesel internal combustion engine
Inventor: FISCHER WERNER
IPC: F02D41/22
Filed: 1982-09-24
Abstract: A control device for a fuel metering system of a diesel internal combustion engine is proposed by means of which in the event of an undervoltage either maximum fuel metering can be set, as for example when starting, or else minimum fuel metering, as for example in the case of a fault in the voltage supply. This on the one hand guarantees reliable starting of the internal combustion engine, and on the other hand ensures that in the event of a drop in the supply voltage in normal running there is no damage to the internal combustion engine or injury to the driver of the vehicle to which the internal combustion engine is fitted. In addition, in the event of a fault in the control path sensor, circuit measures are provided by means of which the control circuit for the fuel metering is interrupted and a proportional regulator used to control the fuel metering instead of the positional regulator. This measure affords the driver a large degree of control over the power output of the internal combustion engine even in the event of a failure of the control path sensor. It is thereby possible to maintain a certain emergency running even under difficult conditions, for example in rough terrain. <IMAGE>

Patent DE-3242967-A1 (DE)
Title: Method and measuring instrument for measuring and processing characteristic quantities of the environmental atmosphere, particularly below ground
Inventor: HUEBNER HANS-JOERG DIPL KFM
IPC: G01N33/00
Filed: 1982-11-20
Abstract: In this method, in which the respective characteristic quantity is measured by means of a measuring instrument and indicated and then stored, clear informative information is obtained and can be processed rapidly and effectively in that the measurement value, after the characteristic quantity has been measured, is normalised to one or a number of parameters in the measuring instrument - triggered manually or automatically, and the normalised and possibly also the absolute measurement value are displayed and/or stored. In this connection, it is possible to input a normalising function or first to carry out calibration measurements and to calculate the normalising function from the calibration measurements. Apart from a power source, a measuring arrangement, an operating unit and a display unit, a corresponding measuring instrument has a normalising stage which is connected, on the one hand, to the measuring arrangement and, on the other hand, to the display unit. Given a correspondingly constructed normalising stage, adjustments at the measuring instrument itself can be omitted since all corrections can be done "mathematically".
