Title: FM demodulator circuit for reducing the noise level in the demodulation result
Inventor: GLAESSNER GILBERT
IPC: H03D3/00
Filed: 1982-09-11
Abstract: In the conventional FM demodulators with ratio detector, signals which approximately reach or even exceed the amplitude of the useful signal are particularly intensively disturbing. This applies both to noise and common frequencies but especially to impulse noise from electrical appliances and car ignition sparks. Figure 1.1 shows the block diagram of the invention. The non-limited FM signal F1 is mixed to form the less modulated FM signal F20. It passes at least through a filter with narrow bandwidth and goes to the limiter as F21. The limited signal F22 is demodulated in an FM demodulator of any type. The result is NF1. An adapter with, for example, amplifier(s), low-pass filter and, if necessary, phase correction provides NF2, the useful signal and drive signal for the VCO. The frequency F3 of the latter is controlled in such a manner that the signal F20 is produced with F1. The phase comparator with a fixed frequency, shown in Figure 1.2, has been found to be a suitable FM demodulator. A further extension is possible by frequency doubling with the method shown in Figure 1.3. In this arrangement, signals with overmodulation with 180 degrees phase shifts are still evaluated. The achievable advantages are drawn for 1kHz in Figure 2.1 and for 15 kHz in Figure 2.2. The diagrams relate to whole modulation VHF broadcast standard. They show the function of the demodulated signal/noise ratio in dependence on the RF signal/noise ratio with impulse and noise interference. ... Original abstract incomplete. <IMAGE>

Title: Indicating device for the degree of filling of a vacuum-cleaner filter bag
Inventor: FLEISCHER WOLFGANG DIPL ING
IPC: A47L9/19
Filed: 1983-01-05
Abstract: The invention relates to an indicating device for the degree of filling of a vacuum-cleaner filter bag. In this indicating device, the pressure difference prevailing in front of and behind the filter bag (31) adjusts a visibly arranged indicating element (5, 21, 32) against a restoring force in proportion to the pressure difference. The indicating element is firmly held in the position reached in each case. A locking means of simple design, which also reliably withstands shock-like vibrations, is achieved by virtue of the fact that the indicating element (5) can be adjusted rectilinearly and has a supporting element (11) which engages in a catch means, directed against the restoring force, of a catch element (16) pressed under the action of force against the supporting element (11). <IMAGE>

Title: Device for a height-adjustable deflection fitting
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: B60R22/20
Filed: 1983-02-21
Abstract: The invention relates to a height-adjustable device (1) for the preferred mounting of a deflection fitting (10). The easy displaceability and freedom from jolting of the adjusting operation is guaranteed in that the positioning can be carried out by a first smooth adjusting catch mechanism (8, 8'; 9, 9') while a second load-receiving blocking gearing (12, 13) engages automatically under load in the case of an emergency. In this case, the first adjusting catch mechanism (8, 9) takes over the respective precise positioning of the teeth (12, 13) of the second blocking gearing relative to one another, so that the proper tooth engagement is always guaranteed in the case of loading. Furthermore, the adjustable slide (3) is connected to a compensating spring (6) so that the vertical displacement forces are largely neutralised. <IMAGE>

Title: Method and device for recording alarm strike signals in winding engines in underground excavations
Inventor: ALBRINK EGON
IPC: G11B31/00
Filed: 1983-04-21
Abstract: A magnetic recording device (1) with at least two tracks is used to record the alarm strike signals. The audible alarm strike signals are picked up by means of a microphone (21) disposed near the alarm and are recorded on a first track. A clock-time speech amplifier (22) is simultaneously activated whose time announcement indicating the respective clock time is recorded on the second track, so that the alarm strike signals are recorded at the correct audible level and are allocated to the clock time. The trailing signal edges of each alarm strike are suppressed by means of a reverberation suppressor (11) in order to prevent reverberation which would adversely affect the reproduction of the alarm strike. A special endless tape cassette (50) which is provided with an ancillary winding disk (56) coupled with the device's own winding disk in order to support the normal capstan drive (52, 53), serves as the sound medium. <IMAGE>

Title: Device for measuring the degree of dispersion of pulverulent materials
Inventor: LOEFLATH ANDREA BEATE
IPC: G01N15/00
Filed: 1984-05-12
Abstract: Measurement of the degree of dispersion of pulverulent materials in liquids is important for testing the dispersivity and its improvement by agglomeration or instantise. It is usual to mix a fixed quantity of the product to be tested into the liquid in a defined way, and to split the still incompletely dispersed suspension into two fractions (dispersed material and residual material) and to determine the solid content in them. For this purpose, the device contains two inherently closed liquid-circulating systems for accommodating in each case one of the two fractions by means of cuvettes through which the fractions are pumped, and a device for measuring the light transmission. In each case one of the two cuvettes is automatically pushed into the beam path thereof. A small computer connected downstream is used to calculate the ratio of the two solid concentrations and thus the degree of dispersion from the measured light transmissions. The desired value is already available within a short time, by contrast with the previous methods.
