Title: Noise and interference suppression in FM radio receiver - using disturbance monitor, consisting of monostable and coincidence stage, in IF circuit
Inventor: HANSEN JENS DIPL ING
IPC: H03G3/34
Filed: 1980-10-30
Abstract: The disturbance monitor comprises a monostable (5) and a coincidence monitor (6). It is placed immediately following the limiting amplifier (4), and between it and the demodulator (9). The monitor acts on a gate (10) between the demodulator and the a.f. amplifier (11). During normal operation the limiting amplifier output is a square wave whose edges trigger the monostable (5) such that the coincidence detector (6), which also receives the same signal, gives a continuous logic high. A disturbance results in a missing edge leading to a logic low which activates a switching stage (7). This functions in conjunction with a counter (13) and opens the gate (10) if the disturbance persists for a predetermined time. The disturbance monitor has rapid response and provides good signal to noise discrimination even at low incoming signal levels.

Title: Process for producing a building material of particularly low damping in the high-frequency range
Inventor: BUSCH DIETER DIPL ING
IPC: H01Q1/42
Filed: 1981-08-18
Abstract: For producing a building material, which has particularly low damping in the high-frequency range but is inexpensive, the constituents used are quartz sand, a binder which has low damping relative to high frequencies, such as, for example, polyurethane, and non-conductive fibres for increasing the strength. Such a building material can also be made in a foamed form in order to reduce the dielectric constant, for example for aerial facings. Another possible field of application concerns three-dimensional phased arrays, where this building material appears to be particularly suitable because of its low costs, the low damping and the high strength.

Title: Burn-out protection for gas valves
Inventor: SCHWARTZ WILLI
IPC: F17C7/00
Filed: 1982-03-16
Abstract: In fittings, such as shutter valves, which are exposed to oxygen surges, there is a risk of burn-out. The heat of compression which arises during the pressure surge must be dissipated. In the split housing, the lower housing part (1) has an orthogonal recess (8) in front of the valve shutter part (6), which recess is connected at the bottom to coaxial lower longitudinal bores (9). The upper housing part (3) has an annular groove (10) in the hole diameter of the lower longitudinal bores (9), from which diameter identical upper longitudinal bores (11) emanate. The multiple deflection and relief of the oxygen pressure surge leads to sufficient cooling, which prevents ignition. <IMAGE>
Patent DE-3213825-A1 (DE)
Title: Automatic rain outlet
Inventor: NEUMANN JOSEF
IPC: E03F5/12
Filed: 1982-04-15
Abstract: In sewage systems of the combined-sewer system, sewage which has been diluted at least five times by rainwater is no longer considered as requiring treatment. To separate out such sewage in good time so as to relieve collecting channels and sewage plants, structures similar in nature to side weirs are generally placed at suitable points of the sewer networks. These structures, known as rain outlets, are however highly imperfect in operation, insofar as they convey much greater quantities of sewage towards the sewage plant than necessary, in the event of above-average precipitation. The consequences of this are backflow in the sewer network together with unpleasant and extremely serious cellar flooding and disturbances or even failure of the operation of the sewage plants. The invention for which a patent is applied eliminates this situation by the fact that, following the fixed conventional overflow channel in the flow direction of the dry-weather outflow, a second overflow channel, which is controlled by a float and provided with a pipe bend at the discharge end and which can move axially, is attached. If, during rain or thaw, the inflow quantity of sewage increases above a certain amount, the discharge end of the channel is lifted and simultaneously its overflow edge lowered, as a result of the increasing water level in the float chamber. This has the consequence that when a given maximum of the inlet quantity is reached, no more sewage flows towards the sewage plant, but the entire quantity not requiring treatment is supplied via a specially constructed drainage channel to receiving water, i.e. river, stream, lake or pond, until the channel automatically returns to its starting position when the precipitation eases off and hence the dry-weather outflow again flows unhindered towards the sewage plant.
