Title: Circuit arrangement for a telephone station with a transistor amplifier and a piezoelectric microphone
Inventor: GUNTERSDORFER SIEGFRIED
IPC: H04M1/60
Filed: 1982-03-18
Abstract: The invention relates to a centrally powered telephone station with piezoelectric microphone and amplifier for direct listening and hands free talking, an impedance transformer providing a small, stable feed current and a low alternating-current resistance with respect to microphone output. The impedance transformer is low-noise and can be connected to all supply voltages from 2V to 100V. The object of the invention is to be seen as that of connecting the impedance transformer to the subscriber station via only two wires of the handset cord. This is achieved (according to the figure) by predetermining a certain operating point for the transistor (T) of the impedance transformer by certain resistor arrangement and resistor rating (R1, R2, R3) and by being able to keep the alternating-current resistance sufficiently small with respect to the input resistance of the wires (A1, A2) used of the handset cord by a corresponding arrangement of a capacitor (C2) and a resistor (R3) . <IMAGE>

Title: Connecting element with a clip effect
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: F16B5/06
Filed: 1982-04-01
Abstract: The invention relates to a connecting element with a clip effect, which is preferably produced from sheet metal without any metal-cutting operations. The compression force is applied by an elastic head part, constructed as a conical flange, and at least one resiliently elastic locking element. Once it has been pressed into a hole, the locking element acts as a clip outwards and thus secures the connection. Predetermination of the initial tension and tolerance compensation for the clamping height are ensured by the resilient construction of the head part. Automatic and semi-automatic assembly of the connecting elements are possible. <IMAGE>

Title: Operating method for a device for examining the female breast with ultrasound, and associated control device
Inventor: KNOCHE JOCHEM DIPL ING
IPC: A61B8/08
Filed: 1982-06-28
Abstract: In such a device, an ultrasonic transducer system is arranged in a movable fashion inside a water-filled applicator. The transducer system can rotate about the axis of symmetry of the applicator and can be swivelled about such an axis of rotation situated near the plane of the applicator opening, for which purpose the transducer system is arranged inside the applicator on a swivellable bracket. In the operating method provided, the ultrasonic transducer system rotates continuously or in steps about the central axis (I) in a prescribable angular position with respect to the application opening, it being possible in each azimuthal angular position of the ultrasonic transducer system (125) to change the imaging angle by tilting about the foot of the bracket (120). In the reproduction of the image on the viewing screen (31) of an image signal processing device (30), it is possible to generate a three-dimensional impression of the image, especially by swivelling to and fro in the angular range provided. For this purpose, for example a function generator (182), in particular a triangular wave oscillator is connected to the nominal-frequency selector (180) in the associated control device (175). As an alternative to this, a control device can be realised by a processor system (190) to which the prescribed functions are fed in a software fashion. <IMAGE>

Title: Process and device for sealing the corner regions of spacer frames in thermal glazing
IPC: E06B3/673
Filed: 1982-07-13
Abstract: The invention relates to a process and a device for sealing the corner areas of spacer frames, such as are used for manufacturing thermal glazing. The aim of the invention is that no sealing compound should be present on the visible part of the insert angle after filling the cavities between the insert angle and the hollow profiles, in order to eliminate post-cleaning by hand. According to the invention the object is achieved in that an injection head is disposed in positive and non-positive connection with the corner region of the spacer frame and the visible part of the insert angle is sealed with respect to the cavities by means of cutters. After filling the cavities with sealing compound the corner region is moved on the guideways of the injection head by an ejector in such a manner that a neat and smooth termination of the sealing compound at the ends of the hollow profiles results. <IMAGE>

Title: Counting mechanism
Inventor: SCHULTZE AXEL
IPC: G06M3/06
Filed: 1982-12-03
Abstract: The invention relates to a counting mechanism for the determination of the number of revolutions of rotating parts and for the determination of the number of steps of parts moving in steps, particularly for mileometers, elapsed-time meters and cash registers, with connections for a signal source and a subsequent counting mechanism for counting pulses or rotation values. The object of the invention consists in developing the counting mechanism of the said type in such a manner that the counts or measurement data can be measured or detected with a relatively high counting reliability as is given in the case of mechanical counting mechanisms, and in processing the detected data in an electronic unit and displaying them with the aid of this unit without the failure of the supply voltage of this unit having the consequence that the count is deleted and can no longer be reconstructed. According to the invention, this object is achieved by the fact that the counting mechanism is constructed as an electromechanical counting memory which has a mechanical counter part, driven by the part rotating or moving step by step, which carries out the counting process in binary manner and is provided with electromechanical or semi-electronic switching contacts for count determination and storage and which are connected to an electrical evaluator (computer) for the stored count.

Title: Cooling-water suction device for resistance welding installations
Inventor: HILLER GUENTHER
IPC: B23K11/36
Filed: 1983-05-07
Abstract: The invention relates to a cooling-water suction device for resistance welding installations. A device of this type fluidically connects a supply network which is on the recooling side and has a feed and return line to a further cooling supply network within a resistance welding installation which likewise contains feed and return lines. The feed- and return-side connection lines which are normally open can be shut off and instead a return of the cooling water contained in the installation-side supply system into the cooling unit-side return line can be brought about, there being provided for this purpose corresponding suction lines which can be shut off and a suction pump. To reduce the investment and maintenance costs, this suction pump is designed as an injector pump which can be driven by a driving line fed on the feed side. The latter can likewise be closed for normal operation.
Patent DE-3319084-A1 (DE)
Title: Geared machine (pump or engine)
Inventor: ROMETSCH WERNER
IPC: F01C21/10
Filed: 1983-05-26
Abstract: In the case of hydraulic geared machines it is essential that leakage gaps be kept as small as possible. Such gaps may form not only between the gear side faces and the adjacent housing walls, but in particular also on the front faces of the gears. In order to reduce such leakage gaps, the gears (14, 15) are allowed to bed into the low pressure area (ND) somewhat. To facilitate this, the housing (10) accommodating the gears is mounted so that axially it is slightly movable in relation to the covers (12, 13) closing it. This is made possible by distance sleeves (42 to 45), the length of which is somewhat greater than the thickness of the housing (10), so that a housing gap (a) is produced. The radial movement of the housing (10) is produced by a certain play between distance sleeves and centring sleeves, which are located in some screw holes (34, 36) receiving the screws (30, 32). By subjecting the housing (10) to pressure from the high pressure side it is displaced by the said amount of play towards the high pressure side so that the gears can bedin slightly on the low pressure side. <IMAGE>
Patent DE-3320679-A1 (DE)
Title: Re-usable frictionally locking securing means for screw/nut of a releasable screw connection
Inventor: LE THANH-SON DIPL ING
IPC: F16B37/14
Filed: 1983-06-06
Abstract: In the case of this principle of the frictionally locking screw/nut securing means, the screw connection is prevented from being lost by the additional frictional lockings preventing automatic loosening. Said frictional lockings are produced by the frictionally locking coupling, if appropriate with auxiliary elements, and are only brought in for securing purposes once the screw/nut connection has been properly tightened. By removing the coupling piece, the additional frictional lockings can be eliminated. During the tightening and loosening procedure, the screw thus does not undergo the relatively high degree of frictional locking as in the case of the self-locking nut/screw connections. The securing procedure is position-independent and reproducible. All the parts used for securing are fully re-usable. By corresponding configurations of the coupling parts, the screw connection can also be secured against seizure and theft and against fragments falling out if the screw breaks. By using coupling sleeves with fitting sleeves, the relative vibratory movements of the braced parts are restricted. In the event of dynamic loadings, the fitting sleeves largely absorb the transverse forces, with the result that a risk of fatigue failure of the screw can be reduced.

Title: Cylinder head for four-stroke internal combustion engines
Inventor: SEIDL JIRI DIPL ING
IPC: F02F1/24
Filed: 1983-08-02
Abstract: A cylinder head for four-stroke internal combustion engines has a concave combustion chamber part. In this an inlet valve and an exhaust valve are suspended forming a relatively small V-angle. Their centre axes lie in transverse planes offset abreast of the V-angle. The spark gap of a spark plug is offset abreast of the exhaust valve and arranged approximately in the transverse plane of the inlet valve. The V angle of the valves is swivelled by an angle of approximately 2 to 10 DEG  to the side of the inlet valve in relation to the associated cylinder centre axis. The combustion chamber part in the cylinder head has an approximately flat semi-streamlined cross-sectional shape in the direction of the V-angle, the relatively high section of the combustion chamber part being arranged in the area of the spark gap and the exhaust valve. The relatively low section of the combustion chamber part on the other hand narrows in a flat key shape in the opposing area comprising the inlet valve and the adjacent projection of the associated cylinder bore and/or to an at least partially enclosing peripheral quench gap.

Title: Crushing device for concrements in the body of a living being
Inventor: REICHENBERGER HELMUT DR RER NA
IPC: A61B17/22
Filed: 1983-08-03
Abstract: The invention relates to a device for the contactless crushing of a concrement (1) in a patient (19), e.g. a calculus in the kidney (15). The required force is exerted upon the concrement (1) by a shock wave. The shock wave generator used is a shock tube (3) which is known per se and which essentially generates plane waves. The plane waves are focussed on the concrement (1) by means of a lens (61). For coupling the shock tube (3) to the patient (19) a first flexible bag (49) which is filled with a coupling medium (47) is used. The bag (49) has folds (51) on its outer wall. This permits the entire shock wave arrangement to be freely shifted in order to adjust the depth and position of the focusing point of the lens (61) in the patient (19). A second bag (.) made of an elastic material is used to decouple the shock waves again after having passed through the body of the patient (19). The first and second bags (49, .) may be combined to form a single bag (67) which surrounds the patient (19). <IMAGE>
