Patent DE-4210786-A1 (DE)
Inventor: STRASEN WERNER DIPL ING
IPC: F16L55/027
Filed: 1992-04-01
Abstract: A resonator for silencing low-frequency noise or individual tones in pipelines is described, in the case of which the resonator chamber (1) is virtually completely separated from the pipeline (2) by a boundary surface. This boundary surface has a change in surface density (thickness) after a length of 1/5 to 2/3 of the overall length of the chamber (2). In the simplest case, this change is brought about by incorporating holes. The resonator has a broadband effect in the low-frequency range and prevents the occurrence of relatively large pressure losses in the pipeline (1). <IMAGE>

Title: Fish-rearing aquarium - has flat-folding resilient sealing pocket pressed against frame sidewalls by water-pressure
IPC: A01K63/00
Filed: 1992-07-01
Abstract: Ornamental fish in particular are reared in a rigid open-topped frame with sidewalls resistant to water-pressure and working with seals so as to form a watertight basin.

Title: Receiver with switching diversity and several aerials - has attenuation control determining induced voltage level of selected aerial output signal.
Inventor: SUGAWARA KAZUAKI
IPC: H04B1/16
Filed: 1992-09-17
Abstract: The receiver has aerial which are selectively switchable for delivering an output signal with the highest induced voltage.

The selector (5) carries out the aerial switching in dependence on the attenuation control signal. The audio signal is attenuated for a preset time period, also based on the attenuation control signal, by a separate attenuator (15). USE/ADVANTAGE - For radio receivers, with reliable switching of aerials in accordance with reception state.

Title: HD MAC encoder - carries out several comparisons between tolerance values of partial pictures of full TV signal
Inventor: ZHANG WENJUN DR
IPC: H04N7/015
Filed: 1992-10-09
Abstract: The encoder transmits an HDTV signal as a series of full pictures divided into partial pictures into a transmission signal with half as many lines. An encoder arrangement (1) performs block-wise selection of one of three set transmission modes according to values of tolerance functions. The signals of the three modes are compared block-wise with the corresponding blocks of the TV signal. The arrangement selects two half pictures of a full picture, between a first mode (20) in which a partial picture of the transmission signal is obtained from each partial picture of the TV signal, and a second mode (40), in which two partial pictures are obtained from each odd part signal of the TV signal. In a second step the arrangement selects, for four quarter pictures, between the first mode and a third mode (80) where four partial pictures are obtained from the quarter pictures. ADVANTAGE - Ensures differentiation between three transmission modes and has less noise disturbance.

Patent DE-4322859-A1 (DE)
Inventor: MUELLER SEPP
IPC: G01M3/18
Filed: 1993-07-08
Abstract: The invention relates to a device for the long-term leak monitoring of double-walled container systems, in particular double-walled tank bottoms, which permits, at low cost, the monitoring of, if appropriate, a multiplicity of double-walled tank bottoms cyclically or simultaneously with respect to the occurrence of leaks. By means of the device it can be established whether a leak has occurred in the outer bottom or in the intermediate bottom, the size of the leak and the location of the leak being able to be determined. According to the invention, an intermediate layer is applied to the inside of an outer bottom, the said intermediate layer serving to support the inner bottom. A sensor cable having a variable dielectric constant is laid in the intermediate layer, protected to a large extent. By means of the special intermediate layer, it is firstly possible to dissipate the forces acting on the tank bottoms and, besides, to lay the sensor cable at defined locations which are known in detail. In order to make possible a prescribed propagation of liquid, the intermediate layers have special recesses or are laid in such a manner that the liquid flow is not impeded. <IMAGE>
