Title: Echo sounding method for measuring water level and waves from the bottom of waters
Inventor: FAHRENTHOLZ SIEGFRIED R J DIPL
IPC: G01S15/88
Filed: 1981-01-12
Abstract: When measuring water level and waves from the bottom of waters by means of echo sounding, it is found in nature that in extreme weather conditions, additional echoes occur between water surface and the bottom of the sea which considerably disturb the detection of the surface of the sea. The basic concept of the invention can be seen in Figure 3 and consists in that the echoes from the water space must mandatorily arrive before the main echo from the water surface. The analysing circuit of the echo sounding water level and wave measuring instrument therefore has the characteristic to detect, in the receiving period, not the first echo, as usual, but the last arriving echo as echo from the water surface. Furthermore, the sounding electronics contain suitable electronic measures with averaging functions which prevent the double echo of the wave trough, which is possible in the meantime under favourable acoustic conditions and which would arrive later than the real echo from the water surface from being able to interfere with the analysis of the water surface echoes.

Patent DE-3121339-A1 (DE)
Title: Device for securing the quick acting closure of the lids of pressure vessels
Inventor: GRAEBER AUGUST
IPC: F16J13/24
Filed: 1981-05-29
Abstract: The invention relates to a device for securing the quick acting closure of pressure vessels, in which, in the closed position, the lid of the vessel engages by means of lugs under dogs arranged on the circumference of a ring on the vessel and can be turned by means of a gear mechanism arranged on the lid and the rim of the pressure vessel. A blocking projection is provided on the lid or the ring of the vessel and, in the release position of the lid, this projection strikes against the associated dog or associated lug and prevents further rotation of the lid. For movement out of the release position, the lid must therefore first of all be pressed against the ring on the vessel and this ensures that the vessel is in fact depressurised when it is next opened.

Patent DE-3135017-A1 (DE)
Title: Heat accumulator mounted in the earth
Inventor: CONRAD HEINRICH
IPC: F24D11/00
Filed: 1981-09-04
Abstract: The object of the invention, using oil tanks mounted in the earth as heat accumulators, if a transition is being made to other combustibles, serves for the optimum use of generated heat. According to the content of the oil tank, combustion cycles are reduced down to 1%, if gas is the combustible in question. If heating is effected with solid fuels, the fire does not have to be maintained throughout the heating period, but it would be a matter of only 100 to 150 combustion operations throughout the heating period, according to the tank content. Heating is carried out rapidly, then the fire is extinguished. An optical or acoustic signal requests the next combustion operation. The high heating-installation efficiency which can be achieved by these means halves the heating-energy consumption. The existing oil tank is highly effectively heat-insulated on the inside or on the outside or both.

Title: Electronic resistor
Inventor: THOMAIER JUERGEN
IPC: G01R1/20
Filed: 1982-10-23
Abstract: The invention creates an electronic resistor suitable, in particular, for measuring technology, which can replace conventional discrete measuring resistors. To simulate such a resistor, a closed-loop control circuit is used which includes a controlling element, the resistance value of which is determined by a manipulated variable. The manipulated variable is formed from the difference between a controlled variable and a reference variable. As a controlled variable, either the ratio of the voltage (U) dropped across the electronic resistor to the current (I) flowing through the controlling element (1) or, alternatively, the current (I) flowing through the controlling element or the voltage (U) dropped across the electronic resistor is used. The closed-loop control circuit is built up with the aid of a differential amplifier (3), which generates the manipulated variable, a current/voltage converter (2) located in series with the controlling element (1), a controlling element (1), a divider (4) or multiplier (5), a digital/analog converter (6) and a digital drive circuit (7). <IMAGE>
Patent DE-3240598-A1 (DE)
Title: Rotating heat recovery device
Inventor: HOAGLAND LAWRENCE C
IPC: F28D9/04
Filed: 1982-11-03
Abstract: The invention describes a rotating heat recovery device which has a matrix formed from plastic and in which the dimensions of the matrix are adapted to specific dimensional parameters. In an exemplary embodiment of the invention, the matrix strip is equipped with transverse bulges which have a length that is less than the strip width, in order to permit a wind-up tension to act on the strip without influencing the dimensions of the bulges. The dimensional parameters permitted by the use of plastic permit the production of matrix discs having a minimum thickness which reduces the circumferential leakage loss. Furthermore, the invention relates to a heat recovery device and method for producing the device in which the matrix has reinforcing elements in order to ensure adequate lateral and rotational strength. These reinforcing elements can, on the one hand, consist of radial fusing grooves or bores whose smooth continuous walls consist of strip layer edges fused with and to one another. On the other hand, thin, wheel-shaped elements can be heated to the fusion temperature of the matrix strip so as to fuse them into the end face of the wheel.

Title: Mirror cabinet having door leaves
Inventor: SCHWARZE JAN
IPC: A47B67/00
Filed: 1982-11-30
Abstract: There is a mirror cabinet having two door leaves (6) with mirror panes, each of which is mounted rotatably about a vertical axis at a distance from the internal perpendicular peripheral edge, by pivoting at a joint (13) fixed to the cabinet body (1) a torsionally stiff spacer (15) whose other end is pivoted at a further joint (16) which is fixed to the door leaf, the height of the door leaf being equal to or greater than the width of the door leaf. The aim in this is for the spacer to have a torsional stiffness improved in a simpler fashion by virtue of its configuration and assignment to the door leaf, in order for the two door leaves inherently from the front of the cabinet not to project as far, when seen from behind, upon opening. This is achieved by providing the removable joint (16) of the spacer (15) in the middle third of the door leaf (6) in each case. The horizontal dimension of the spacer is thus approximately only half of the smaller dimension of the door leaf. <IMAGE>

Title: Generator for generating a sine-wave voltage with a frequency selectable between two fixed values
Inventor: HAHN EBERHARD DIPL ING
IPC: H04M15/00
Filed: 1983-01-31
Abstract: Generator for generating a sine-wave voltage has a crystal-controlled oscillator whose clock signals are divided by digital divider circuits into two pulse strings whose pulse string frequencies are in each case two times higher than the frequencies of the required sine-wave voltage. These pulse strings are alternatively fed via a changeover device (S) to a flip-flop (FF) where they are converted into a square wave at half the frequency. All harmonics are eliminated from the square wave in a low-pass filter (TP) designed as a third-order Tschebyscheff filter. In its pass band, the low-pass filter (TP) has a relative attenuation minimum which lies between the required fixed values of the frequency, such that exactly identical attenuation values and therefore identical output voltage amplitudes are created at both frequencies. <IMAGE>
