Patent DE-3442205-A1 (DE)
Title: Direction-indicating device for land vehicles
Inventor: HAU CHUNG TAI
IPC: B60Q1/40
Filed: 1984-11-19
Abstract: The subject of the invention is a direction-indicating device for land vehicles, in which, without monitoring by the driver and without inadequate mechanical restoration, the flashing continues, after triggering by the driver, for an appropriate time and is then automatically ended, in particular after a flashing duration which is dependent on the travel speed. For this purpose, in each case one transistor (Q3, Q4) is connected into the feed circuit of the direction flashing lights (11, 12) in addition to a flashing interruptor (8), which transistor (Q3, Q4) is driven via an invertor (21, 22) whose input level is obtained from a RC circuit whose capacitor (C1, C2) is charged by the actuation of the direction-indicating switch (10) and whose discharge time constant determines the duration of flashing. In order to influence the said constant by the travel speed, an earthing switch (6) is connected into the discharge path of the time setting capacitor (C1, C2), the said earthing switch (6) being installed in the tachometer shaft and periodically enabling a charge discharge path from the time setting capacitor (C1, C2) as a function of the speed of rotation of the said shaft.

Title: Hand-held circular saw or similar electric tool having a motor and gear housing of a two-shell design
Inventor: FUCHS MICHAEL DIPL ING
IPC: B27B9/00
Filed: 1985-02-14
Abstract: In the case of hand-held circular saws or similar electric tools having a housing of a two-shell design, a bearing shell for receiving the output-side bearing for the working spindle being formed on each shell half, in many cases there arises the problem of inadequate space for bracing the bearing neck situated on the output side by means of screws. In order in such cases to be able to dispense with the use of additional components in the form of tension bands or separate ring elements, which also take up additional space and as a result prevent the bearing neck being used for other functions, the invention provides that the bearing neck (8) formed by the two bearing shells is enclosed and held together by an already existing component of the saw situated on the output side and provided with a hollow hub (9) (Fig. 1). <IMAGE>

Title: Method for monitoring the turning action of a screw
Inventor: MAJIC MILIVOJ DIPL ING
IPC: B23P19/00
Filed: 1985-03-29
Abstract: In the production of screw connections in mechanical production plants, instances of defective screws can come about inter alia due to the fact that the screw has thread damage or is applied at a slant, or that chips are present in the blind bore. In order to increase the reliability of screw connections, the method according to the invention for monitoring the turning action of a screw in a workpiece provides that after the fastening torque and turning path of the screw Md = f(s) the turning action is also already detected in the screwing phase before achievement of the applying torque Ma and of the turning path s phi  by means of the measured-value transmitter for the torque and for the turning path, and the signals obtained in this phase are evaluated in a microprocessor system (Fig. 3). <IMAGE>

Title: Schematic representation and method of operation for causing a flying object to make the transition into a hovering state and to continue to move
Inventor: DICHTL PETER
IPC: B64B1/62
Filed: 1985-11-05
Abstract: This invention discloses the schematic representation and method of operation by means of which a flying object can be driven forward from a hovering state S1, using muscle power by means of a propeller 9 etc. with a control system 10, and can be directed in the desired direction. Gas is used as an aid to the lift P3. This saves muscle power which is required for lifting the flying object, its own load plus the useful load and people etc. The gas has the property of reducing rather than increasing the lift force P3 when an identical spatial volume at the normal specific volume weight is compressed. The lift force P3 does not rise until it has expanded to the normal specific normal volume, and the falling force P2 is then reduced. Since the flying object consists of at least two balloons 4 and 5, which are connected to one another by means of channels or tubes 6 which are equipped with valves 13 and are filled with such a volume of gas that the intrinsic load plus the useful load is lifted without gas pressure. After the filling of the balloons 4 and 5 with the volume of gas required for the lift P3 without compression and without pressure has been completed, the flying object rises. If the balloon 4 is compressed by the gas from the balloon 5, then the lift volume is reduced and the lift force decreases, and a hovering state S1 is thus reached. On further compression of the balloon 4, the gas volume is further reduced and ... Original abstract incomplete. <IMAGE>

Title: Filter circuit for influencing the resolution of a video recording luminance signal reproduced on a screen
Inventor: REIME GERD
IPC: H04N5/931
Filed: 1985-11-09
Abstract: In the playback channel (15) for the frequency-modulated luminance signals (YFM) of a video playback device, a filter circuit (14) with two parallel branches (22, 30) is placed between the video head (2) which scans a video medium (1), and an FM demodulator (11). The first branch (22), with the input- and output-side impedances (25, 26), forms an acceptor circuit (27), the low-frequency half of the resonance curve of which extends over the frequency bands of the video medium which are assigned to the luminance signal (YFM). The LR serial circuit (30) raises the lower-frequency part of the resonance curve to a step value, and bends the phase response of the filter circuit so that it removes the phase errors of the frequency-modulated luminance signal to a large extent, so that with a simple circuit design a high luminance resolution of the reproduced video picture is achieved, without reflections or intermittent sputters at the luminance boundaries. <IMAGE>

Title: Device for maintaining constant the internal pressure in an injection mould
Inventor: SCHMIDT ANNEMARIE
IPC: B29C45/56
Filed: 1986-03-15
Abstract: In an injection mould, a channel connected to the feed channel is provided. In this channel, a pin, pretensioned with a restoring force, is arranged so as to be movable in the manner of a plunger. When the mould cavity is filled with injection moulding material and the hydraulic drive of the screw of the injection moulding machine is switched over to holding pressure, a pressure surge in the mould cavity and in the feed channel can occur by virtue of the inertia of the (still moving) material. This pressure surge is avoided or kept small and uniform by, at the commencement of development of the pressure surge, moving the pin in opposition to its restoring force and thereby opening up a chamber which receives the injection moulding material additionally fed by virtue of the material inertia, so that the pressure surge cannot develop.

Title: Method for edge detection
Inventor: HINKEL RALF
IPC: G01B11/02
Filed: 1986-04-10
Abstract: The invention relates to a method for edge detection which has a high measuring accuracy, in particular for the precise determination of position of contrast transitions on discrete optical receivers. The object of the invention is to provide a method which, in the case of discrete optical receivers such as, for example, CCD image converters, permits contrast transitions to be determined more accurately than prescribed by the spacing of the receiving cells. This object is achieved in the case of the method according to the invention due to the fact that the differences in intensity of the adjacent receiving cells in relation to the cell onto which the image of the contrast transition falls are used for the precise determination of the position of the edge.
