Title: Hot-water heating system
Inventor: SCHALLENBERG EMIL
IPC: F24D12/02
Filed: 1981-02-21
Abstract: The invention relates to a hot-water heating system having a main heating boiler, in particular coal heating boiler, whose combustion chamber, provided with a fresh-air inlet which can be regulated, is connected, via a flue-gas outlet, to a waste-gas line leading to a chimney and whose hot-water chamber is connected, via a supply connection, to the supply line and, via a return connection, to the return line of a heat-consumer circuit. In order to adapt the operation of the system to vastly different heat-consumption conditions there is assigned, to the main heating boiler, a supplementary heating boiler which is designed for a lower heating output and is connected, at least for changeover operation, to the waste-gas line and to the heat-consumer circuit, in which changeover operation, in a first operating position, the main heating boiler is fired and the unfired supplementary heating boiler forms a heat exchanger which, in the waste-gas line, is connected downstream of the main heating boiler and, in the return line of the heat-consumer circuit, is connected upstream of the main heating boiler, and in which, in a second operating position, the supplementary heating boiler is fired and the connection of the unfired main heating boiler to the heat-consumer circuit and to the waste-gas line is interrupted.
Patent DE-3123558-A1 (DE)
Title: Device for holding steel bars
Inventor: BRUECKELMANN HEINZ
IPC: B21D7/022
Filed: 1981-06-13
Abstract: The invention provides a device for holding steel bars to be bent on a bending machine. In the prior art, steel bars are supported during bending by means of a counterholder on which they are held, using a holding device, even before they are gripped by the bending tool. One known holding device is a fork outside the bending plate but this does not enable bars of different diameters to be held one above the other. On the contrary, it must then be replaced by a fork with an appropriate prong width. In addition, this does not allow bars to be held in the immediate vicinity of the gap between the bending ram and the bending tool. The invention provides a modified form of the holding device. The holding device according to the invention consists of a lever which, at one end, has an angled arm of equal length to the height of the bars lying one above the other and, between its two ends, is supported in such a way that it can be pivoted with its arm towards the counterholder. This lever is pressed on by hand and thus allows bars of any diameter to be clamped fast on the counterholder. Since the location of clamping can be freely selected, the angled arm can with particular advantage be brought to bear on the counterholder in the vicinity of the gap between the bending ram and the bending tool and this allows the clamping even of very short lengths of bar.

Title: Hedge shears which are driven by an electric motor
Inventor: SCHMIDT ALFRED ING GRAD
IPC: A01G3/053
Filed: 1981-07-17
Abstract: The invention relates to hedge shears which are driven by an electric motor and in the case of which the shaft for the drive of the shear blade is driven by a gear wheel which is in engagement with a pinion attached on the driving shaft of the drive motor, and between the driving shaft of the drive motor and the shear-blade drive there is provided a mechanical separating point which is designed as a coupling and is formed by the gear wheel, which is provided with coupling claws on its shear-blade-side surface, can be displaced axially on the shear-blade shaft counter to the force of a restoring spring and can rotate freely on said shaft, and by a driving plate which has counter-coupling claws and is firmly attached on the shear-blade shaft. Said hedge shears are to be improved to the effect that the coupling and uncoupling procedure between the driving shaft of the drive motor and the shear-blade drive is to take place so rapidly that danger of injury to the operator when the shear blades are coasting is virtually exluded. This is achieved in that the restoring spring is supported on the hub of the driving plate and the gear wheel driving the shear-blade shaft is provided with helical gearing which effects an axial force component which overcomes the force of the restoring spring when the drive motor is switched on and is smaller than the restoring force of said spring when the drive motor is switched off.

Title: Circuit device for digitisation and extreme value calculation of analog signals
Inventor: MOHR WALTER DIPL ING
IPC: G01N29/11
Filed: 1981-07-17
Abstract: A circuit device is described for digitisation and extreme value calculation of analog signals using an analog/digital converter (92) which preferably operates according to the parallel method (A/D converter). In order to prevent the number of comparators used in the A/D converter (92) from becoming too great despite an extensive dynamic range and high accuracy, a measurement range evaluation circuit (8) is connected upstream of the A/D converter (92) which comprises at least two parallel circuit branches (81, 82; 83, 84) and in each case contains an analog extreme value memory (82, 84). An amplifier (81) is connected upstream of the extreme value memory (82) in at least one of the circuit branches (81, 82; 83, 84) so that this circuit branch (81, 82) defines a measurement range which is more sensitive compared with the other circuit branch (83, 84). The input of the A/D converter (92) is switched automatically from the less sensitive to the more sensitive measurement range whenever the analog voltage present in the extreme value memory (82, 84) of the more sensitive measurement range reaches a pre-defined limit. <IMAGE>

Title: Method for measuring the optical transmission response of glass fibres
Inventor: FELDMANN JUERGEN DR ING
IPC: G01M11/00
Filed: 1982-01-14
Abstract: The invention relates to a method for measuring the variation in the optical transmission response of glass fibres under the action of tension, compression, temperature, etc. on the glass fibres, and due to aging of the glass fibres. An optical transmitter (1 in Fig. 1) is modulated by a generator (2) by means of a signal, the fundamental frequency of which is at least of the order of magnitude of the 3-dB cut-off frequency of the transmission band of the glass fibre to be measured. Advantageously, it is significantly thereabove. The optical signal produced passes via the glass fibre (3) to be measured to a receiver (4) which converts the optical signal into an electrical signal. The change in the amplitude and/or phase of the output signal is determined at a measuring station (5) which additionally - if necessary via a line (6) - receives a reference signal from the generator (2), and related to the environmental influences acting on the glass fibres (3) (e.g. by correlation investigations). As a consequence of the signal oscillation frequencies above the 3-dB cut-off frequency, even the smallest changes in the transmission characteristics become clearly evident. <IMAGE>

Patent DE-3206444-A1 (DE)
Inventor: REIMANN HANS DR
IPC: C02F3/30
Filed: 1982-02-23
Abstract: This invention relates to a process for the biological purification of phosphate-containing wastewater wherein the wastewater is gas-treated, i.e. aerated, in an oxygenation tank in the presence of activated sludge for degrading organic hydrocarbon compounds and absorption of phosphate by microorganisms present in the activated sludge. The wastewater-activated sludge mixture is then withdrawn from the oxygenated tank and divided, in a post clarification stage, into purified, essentially phosphate-free water and phosphate-containing sludge. The phosphate-containing sludge is recycled, at least in part, into the oxygenation tank. A partial stream of wastewater-activated sludge mixture is branched off from the oxygenation tank, and/or recycle sludge is branched off as a partial stream from the post clarification stage, and the mixture is subjected to flotation treatment for thickening. A thus-obtained, low-phosphate flotage, i.e. subnatant liquor, is discharged from the flotation unit. Likewise, resultant, phosphate-rich flotage sludge, i.e. thickened floating sludge, is discharged and heated, and after this heating, is treated anaerobically and mixed with wastewater to be purified. Subsequently, the wastewater-flotage sludge mixture is subjected to a phosphate separation and thus-produced, low-phosphate sludge is recycled into the oxygenation tank, and phosphate-enriched liquid is further treated.
