Abstract: A force transducer, particularly for the ballistic measuring of the combustion pressure in the cartridge case of a firearm, is disclosed which includes a force transmission element which rests with one of its front areas on the cartridge case. The force transmission element is surrounded on its exterior by an outer sleeve which also rests with its front area on the cartridge case. The front areas of the force transmission element and of the outer sleeve are exactly adapted to the curvature of the cartridge case by reaming after the transducer has been mounted in the firearm. With the combustion of the powder, the cartridge case expands and transmits its force to a sensor element via the force transmission element, with the sensor element being preferably in the form of at least one piezoelectric transversal quartz element which is held under pretension between the force transmission element and a basic receiver component. The spring rigidity of the force transmission element and the spring rigidity of the outer sleeve are matched in such a way that both parts yield essentially to the same extent to the pressures acting upon them in the axial direction of the transducer. The result is that the contact conditions of the cartridge case with the front area of the force transmission piston do not change appreciably after the expansion in comparison with the initial conditions so that a calibration curve of the force transducer which is independent of the installation can be supplied by the manufacturer.

Title: Method for measuring the attenuation pattern of a four-pole network disposed in an electrical device
Inventor: ZIMMERMANN ROLF DIPL ING
IPC: G01R27/28
Filed: 1981-02-12
Abstract: To measure the frequency dependence of an active or passive four-pole network, sweep signal generators are used in radio-frequency systems in conjunction with oscillographs. If the attenuation pattern of an input band filter in a radio device is defined with a measurement set-up of this type, a parallel loading of the input of the mixing stage causes a deformation of the bandpass characteristic. The narrowband quartz filter disposed on the output side furthermore requires a disconnection of the mixing stage and a relatively expensive equivalent circuit. To define the frequency dependence of the amplitude of the four-pole network (31), the AC voltage occurring at the output of a further four-pole network (32) electrically following the four-pole network (31) is defined. To prevent the latter's frequency response from affecting the measurement signal, a second measurement frequency (f2) is fed to the further four-pole network (32) which changes to the same extent as the first measurement frequency (f1) and differs from the latter by the same frequency spacing (fZF1) during tuning. <IMAGE>

Title: Lifting gear for bottom feeders of sewing machines
Inventor: ZWICKER KARL
IPC: D05B27/02
Filed: 1981-04-27
Abstract: The invention relates to a lifting gear for bottom feeders of sewing machines for the optimum gear design for the purpose of the best possible restriction of the sound emission of sewing machines with a high stitch frequency. For this purpose, the forces triggering rebound impacts when the sewing foot is braked on the needle plate by the feeder penetrating into the needle plate must either be eliminated completely or be reduced decisively. These rebound impacts account for an appreciable proportion of the noise emission of sewing machines with bottom feed. By extending the gear, the vertical speed component of the feeder when it enters and leaves the needle-plate plane is substantially lower than the maximum value. The lifting gear can be used in all sewing machines with bottom feed, irrespective of the type of stitch to be formed and of the form of construction of the sewing machine. Furthermore, it is also suitable for other machines which are to move linear or sheet-like work articles intermittently. <IMAGE>

Title: Circuit arrangement for controlling the motor current of electronically commutated DC motors
Inventor: ZAHN DIETER
IPC: H02P6/06
Filed: 1981-04-29
Abstract: The invention relates to a circuit arrangement for controlling the motor current of electronically commutated DC motors, having n switching stages and n stator coils or coil groups, where n >/= 2, in order to regulate the motor speed. The object of the invention is to control the current supplied from the switching stages into the stator windings by means of a regulation signal emitted from the loop filter of the speed regulating section in such a manner that the motor speed is kept constant, using the motor current as the control parameter, when the load torque changes. This is achieved according to the invention in that the sum of the coil currents flowing through the star point is always identical to the value predetermined by the speed regulating section for regulating the motor speed, irrespective of the instantaneous drive of the individual stator coil, in that a resistor is arranged in the star point of the motor and the voltage signal obtained with it, which is proportional to the motor current, is subjected in an operational amplifier to a continuous comparison with the regulation signal predetermined by the regulating section.

Patent DE-3142903-A1 (DE)
Title: Burner
Inventor: JOOSTEN PAUL
IPC: F23D14/08
Filed: 1981-10-29
Abstract: For burners which work with a fuel/air mixture, there are already fan jet versions which are to be operated with high pressure of liquid fuels and give a correspondingly expanded flame formation. For fuels with lower fuel pressure, in particular for gaseous fuels, the flame position at the outlet opening in such burners is not stable in so far as it can flash back into the mixing chamber. This leads to heating of the mixing chamber, which usually consists of steel, as a result of which it can be destroyed. The invention envisages an improved burner of this type, in which it is guaranteed that the flame is kept constantly at the outlet opening of the mixing chamber and also burns there uniformly and with a shorter length. This is achieved by a round bar close to the outlet opening inside the mixing chamber and in its middle, as a result of which the flow is constricted in each case between an inner wall of the mixing chamber and the adjacent section of the round bar and then widens again. A flow rate is thus reliably achieved, which first becomes greater than the ignition rate and then smaller again. At the same time, this arrangement serves to improve the distribution of the mixture to be supplied over the entire length of the outlet opening.
