Patent DE-3738799-A1 (DE)
Title: Drive arrangement
Inventor: HAACK REINHOLD DIPL ING
IPC: F16D48/06
Filed: 1987-11-14
Abstract: The invention proposes a drive arrangement, particularly for motor vehicles, which has a driving engine formed by a reciprocating-piston internal combustion engine (1), a flywheel (4a) connected to the output of the driving engine, a gearbox (7) and a friction clutch (3) which is arranged between the flywheel (4a) and the gearbox (7) and can be controlled in its torque transmission behaviour by corresponding control of a servo actuator (10) provided for the purpose of actuation. In order to avoid the noise (gearbox chatter) which arises in the gearbox especially in the case of idling speeds and high loads, the proposal is that the servo actuator (10) should be controlled in such a way that the torque that can be transmitted by the friction clutch (3) is at least temporarily limited to a value below the maximum driving torque which can be produced by the driving engine (1), that a torque excess which arises in the case of driving torques above this limiting value essentially balances out a torque deficit which arises in the case of driving torques below this limiting value. <IMAGE>

Title: Method for functional calibration (tuning, trimming) of an electronic circuit
Inventor: SCHMIDT LOTHAR DR
IPC: H01C17/22
Filed: 1988-04-22
Abstract: A method is proposed for functional calibration of an electronic circuit having at least one calibration resistor (R2) as a circuit element, in the case of which method one function (UR2) of the electronic circuit is measured and the resistance value of the calibrating resistor (R2) is at the same time varied until the measured function (UR2 is in the desired tolerance band. The resistance value of the calibration resistor (R2) is varied especially by material removal, in the form of a laser cut (12). The calibration process is carried out in a first method step in modified operating conditions at an increased calibration rate, and in a second method step (which follows said first method step) in operating conditions at a reduced calibration rate. Once the second method step has been completed, the measured function (UR2) of the electronic circuit is in the desired tolerance band. <IMAGE>

Title: Method and device for checking the serviceability of the print needles of a needle print head
Inventor: KOENIG JOHANNES
IPC: B41J9/54
Filed: 1988-07-25
Abstract: In the case of a method for checking the serviceability of the print needles of a needle print head, which needles strike against a printing abutment during printing, the vibration of the same which occurs when a print needle strikes against the printing abutment is detected. A signal corresponding to the vibration is correlated with a drive signal for the relevant print needle so that an error signal is produced in the absence of a vibration signal associated with the drive signal. In order to detect the vibration of the printing abutment, the said printing abutment is connected to an accelerometer whose measurement axis is directed parallel to the movement direction of the print needles.

Patent DE-3828484-A1 (DE)
Title: Drive for a fire protection roller gate
Inventor: BANNIER GEORG
IPC: E05F15/20
Filed: 1988-08-22
Abstract: The invention relates to a drive for a fire protection roller gate, having a motor and a brake on the motor, the brake being liftable by means of a lifting lever. Coupled to the lifting lever is a connecting rod which is passed through the anchor plate of a magnetic clamp, which can be switched on in the event of an alarm, into a housing of an automatic control device. In this housing there is a spindle with a switching nut which interacts with corresponding microswitches for the end positions of the roller gate and through which the connecting rod is passed and which is provided at the end with a stop. The latter causes the lifting lever to be restored again via the switching nut when the closed position of the roller gate is reached, as a result of which the anchor plate is brought into contact with the magnetic clamp via corresponding springs so that the roller gate is ready for operation again by simply switching on the accumulator current and when it has been moved into the defined lower end position.
Patent DE-3833990-A1 (DE)
Title: Balloon-tipped catheter
IPC: A61B17/22
Filed: 1988-10-06
Abstract: In the balloon-tipped catheter of the main application P 3813227.3 in which a coagulating laser light bundle is obliquely coupled into an optical fibre such that it emerges laterally over the transparent catheter and balloon walls at the distal catheter end with circumferential radiation characteristics and thereby exerts a coagulating and stabilising effect on the dilated vessel wall, a second laser light bundle with a fairly pronounced ablative effect is coupled, according to the invention, in the proximal light guide front face such that it emerges with essentially axial radiation characteristics in a manner directed towards a light guide channel extending to the catheter tip at the distal light guide end separately from the first light bundle, as a result of which arteriosclerotically narrowed, organic hollow vessels can be effectively recanalised by independently controlled, individually meterable application of the laser balloon method, on the one hand, and of the ablative laser method, on the other hand.

Filed: 1989-03-02
Abstract: A hose clamp comprising a strip (1) has one bracing jaw (5) at one strip end (4) and a second bracing jaw (7) at a distance from the other strip end (6). Formed in the strip-end portion exhibiting the first bracing jaw (5) is a through-passage (8) with an axial edge (9) which can be hooked in behind a hook (10) projecting between the second bracing jaw (7) and the other strip end (6). In order to be able to brace and open the hose clamp in a simple manner under high loading, a single hook (10) is bent off radially at the end of a tongue (12) formed in a strip cutout (11). Formed between the through-passage (8) and the strip end (4) provided with the first clamping jaw (5), on the inner side of said strip end, is a circumferential groove. At least at the groove end adjacent to the through-passage (8), the groove depth is smaller than the radial distance of the radially outer hook end from the inner side of the tongue (12). The groove width (b) corresponds to that (b') of the hook (10). The edge (9) which comes to bear against the hook (10) forms a base line of the through-passage (8). <IMAGE>

Patent DE-3913283-A1 (DE)
Title: The hydraulic silencer (sound-absorber) with filter effect
Inventor: SCHULZ LUTZ
IPC: F01N3/04
Filed: 1989-04-22
Abstract: Gases which are still under pressure and are released into the environment after the working cycle, such as the exhaust air of compressed-air devices or exhaust emissions, expand to cause sound waves, that is to say noise. The hydraulic silencer provides optimum sound insulation in conjunction with minimum loss of energy. The gases which are still under pressure are guided into a liquid where they rise by virtue of the static lift in the liquid. The expansion is accomplished upstream of and in the liquid, and decompressed gases can therefore be discharged into the environment. Application is possible wherever compressed air units are used and the aim is to remove the offending noise. Retrofitting is possible, and this hydraulic silencer can be provided as standard by the manufacturers of compressed air devices. A further field of application is internal combustion engines. Apart from optimum sound insulation, use can be made here of the filter effect which arises as the exhaust gases traverse the liquid.
