Patent DE-3235187-A1 (DE)
Title: Vehicle window
IPC: B60J1/08
Filed: 1982-09-23
Abstract: In a vehicle window, in particular for buses, it is provided to lock the profile frame bearing the window pane(s) in the window opening by means of a multiplicity of short stop strips. The profile frame has a screw mounting groove extending away over the length of the profile in order to optionally receive the holding screws of the stop strips. The stop strip consists preferably of a multi-legged leaf spring, the one leg of which serves as a mounting leg. Another leg serves for the abutment of the profile frame against the edge of the vehicle body opening whilst at least a third leg engages in the circumferential gap between profile frame and vehicle body cut-out. The two last-mentioned legs can be resiliently prestressed by being arched into one another and thus act in a particularly tolerance-compensating manner. The leg engaging in the circumferential gap between profile frame and vehicle body cut-out also prevents the abutment strip from twisting if it is attached to the profile frame with only one screw.

Patent DE-3244161-A1 (DE)
Title: Moisture-repellant lining of fibre mats and process for the manufacture thereof
Inventor: PELZ ERNST
IPC: B60R13/02
Filed: 1982-11-29
Abstract: A moisture-repellant interior lining of fibre mats or similar materials is presented in which the edges (10) of the fibre mats (12) are bent off towards the wall (14) to be covered and are in contact with this in a surrounding and water-tight manner. The process for manufacturing this interior lining provides for a sealing material to be applied to the side directed towards the car body, which sealing material, when it is used not in a liquid or foam-like form but in film form, adheres to the sealing film in one work stage simultaneously with the compression moulding of the fibre mats, the synthetic resin being used as adhesive, which resin also serves to stabilise the fibre mat during compression moulding. <IMAGE>
Patent DE-3244941-A1 (DE)
Title: Level converter for multi-stage radio-frequency amplifiers
Inventor: ZEISEL KAREL ING GRAD
IPC: H03G3/20
Filed: 1982-12-04
Abstract: In the level converter for radio-frequency amplifiers according to the invention, preferably broadband amplifiers for receiving antenna systems, an electronically adjustable attenuating section is in each case inserted at the inputs of the first and a following amplifier stage. By continuously changing an adjustment voltage, first the attenuation 2 of the second attenuating section can be set up to the maximum value and only then the attenuation 1 of the first attenuating section at the input of the first amplifier stage. The invention has the advantage that, due to the attenuation of the subsequent attenuating section, output levels which are too high can be lowered without noticeably reducing the signal/noise ratio and the amplifier input. It is advantageous for this purpose to select the attenuation of the subsequent attenuating section to be less than the preceding gain. It is only when this attenuation is not sufficient for avoiding cross modulation interference due to output levels which are too high, for example in a broadband amplifier which is supplied with several received signals having different levels, that all input levels are additionally decreased by the preceding attenuation. The resultant reduction in signal/noise ratio, which is disadvantageous for low received levels, is accepted.
Patent DE-3301494-A1 (DE)
Title: Method and device for detecting surface patterns on different objects
Inventor: PIETZSCH LUDWIG DR ING
IPC: G06V10/10
Filed: 1983-01-18
Abstract: A method for detecting surface patterns on different objects, such as newspapers, by means of optical sensors is proposed, the objects being identified by different actual surface patterns such as newspaper titles. According to the invention, a characteristic optical value of the actual surface pattern is recorded line by line in at least one preferred direction of the object and compared line by line with corresponding stored values of all previously recorded nominal surface patterns for all objects. The result of the comparison is added together. The object which exhibits the least deviation of the sum formed from the corresponding value of the relevant reference object, in comparison with the stored values, is recognised as correct.
Patent DE-3304969-A1 (DE)
Title: Shearing mill
Inventor: BUCHHOLZ HANS
IPC: B02C17/16
Filed: 1983-02-12
Abstract: The principle of stress by shearing action is used for dispersing or grinding solids or concretions of solids. The shearing action results from the speed difference between the fixedly mounted mill housing and the grinding body which rotates at high speed. The shearing mill makes possible higher shear than hitherto available grinding and dispersing assemblies, simplified construction and minimising of wear at faster continuous operation.

Title: Method and arrangement for charging an accumulator containing an electrolyte
Inventor: KALBERLAH ADOLF DIPL PHYS DR
IPC: H02J7/00
Filed: 1983-03-10
Abstract: In order to achieve a recharging phase of adequate length even in the case of a plurality of successive partial charges of an accumulator, the short recharging phases resulting from the main charging phases are stored until their total reaches a minimum value which is sufficient to equalise the electrolyte. The charging of a corresponding recharging phase does not take place until then. <IMAGE>
Patent DE-3311204-A1 (DE)
Inventor: BURKHARDT HORST DR
IPC: G01B21/00
Filed: 1983-03-26
Abstract: An incremental measuring system is disclosed in which a reference position can be determined at any time. A rotating carrier body carries an additional incremental graduation for which scanning fields are arranged on a scanning plate. During a calibrating operation an additional marking on the rotating carrier body is used to determine coincidence with an associated scanning field. At this point a measuring value counter is started which counts graduation increments associated with rotation of the carrier body by means of associated scanning fields until the measuring value counter is stopped. This stopping of the counter is controlled by a signal generated on coincidence of an additional marking of the carrier body with the next reference mark on the graduated disc which carries the measuring graduation. Simultaneously, an additional marking of the carrier body reads a code mark associated with the reference mark. Each of the code marks contains in coded form the absolute position of the associated reference mark with respect to the zero point of the measuring graduation. The reference position is determined from the counting value of the increments which are superposed on the absolute position value of the overrun reference mark.

Title: Apparatus for adjusting the distance of the stripping plate from the circumference of the work rolls mounted in the chocks of a roll stand
Inventor: JANSEN JOHANNES
IPC: B21B39/16
Filed: 1983-04-02
Abstract: In apparatuses for adjusting the distance of the stripping plate from the circumference of the work rolls mounted in the chocks of a roll stand, it should be possible to adjust the distance of the stripping plate from the circumferential surface of the work rolls when changing the work rolls or to adjust the distance progressively to the decreasing diameter of the work rolls during rolling without significant technical outlay. For this purpose it is proposed that retention stops 10 lying in the path of motion of abutment stops 8 secured on the supporting slide 6 be arranged on the chocks 11, and the stop faces 8a and 10a of both stops 8 and 10, respectively, be inclined towards the rolls 3, 4 and extend at an acute angle to the vertical (see Fig. 1). <IMAGE>

Patent DE-3322710-A1 (DE)
Title: Optical distance-measuring device
Inventor: SCHUESSLER HANS H DR ING
IPC: G01B11/02
Filed: 1983-06-24
Abstract: A distance-measuring device which operates optically in a contactless fashion projects onto the surface of a measurement object measuring light which is polarised in two mutually perpendicular planes. Electrooptical components located in variable magnetic or electric fields and transirradiated by the measuring light vary their reflection characteristics as a function of field strength. A birefringent component is used to generate focal points which are situated sequentially on the optical axis but whose separation can be varied continuously in opposite directions, as a result of which it is possible to achieve different resolutions. An equidistant focal point displacement is achieved by means of a further electrooptical component, which is, however, isotropic. An excellent position of the focal points relative to the surface of the measurement object can be found by continuously comparing the intensities of the reflected light of both differently polarised types of light in two optoelectronic transducers. Both equidistant and oppositely directed variations in focal point position can be carried out simply and quickly. As a result, the distance-measuring instrument can be universally applied, i.e. its resolution can be quickly varied and measurements are possible at high speeds without mechanical tracking.
