IPC: A62D3/40
Filed: 1986-11-21
Abstract: Emissions of heavy metals during the firing of mud are avoided by an addition of iron oxide. Aggregate material for concrete can be produced from river silt mixed with red mud by firing. Pollutants in the firing waste gases are converted into liquid concentrates. Chlorinated aromatics and other organic pollutants which arise are forced through red-hot fine-pored material and thus pyrolysed to give harmless substances.
Patent DE-3701614-A1 (DE)
Title: Tube heat exchanger
Inventor: KAPPENBERG BERND
IPC: F28F1/00
Filed: 1987-01-21
Abstract: In tube heat exchangers of the known type, in the event of leakages there is a risk of an at first unnoticed mixing of the two media carried through the heat exchanger with the risk that heavy damage may result. In order to increase the safety, the novel tube heat exchanger exhibits tubes, which in each case are designed as concentric double tubes (2) with an essentially smooth tube (3) and a tube (4) exhibiting deformations changing the diameter, one of the two tubes (3, 4) functioning as the internal tube (3) and the other of the two tubes (3, 4) functioning as the external tube (4), which tubes are in contact with each other over parts of their surfaces (31, 40) facing each other and between which tubes in the area of the other parts of their surfaces (31, 40) facing each other, in the longitudinal direction of the tubes (2, 3, 4) media-permeable intermediate tube spaces (5) are formed. In the event of leakages, the novel heat exchanger allows for harmless flowing out of leaking amounts of one of the two media through the intermediate tube spaces and also offers effective heat transmission as a result of the direct contact existing on part surfaces between internal and external tubes. It is especially suited for heat transmission of aggressive and/or poisonous media to, for example, drinking or service water. <IMAGE>

Patent DE-3712579-A1 (DE)
Inventor: GRAS ELIE
IPC: B05D3/02
Filed: 1987-04-14
Abstract: A raw leather piece for use, for example, in making shoes or fancy leather goods is finished by applying a dressing and then a finishing composition to an intermediate support, independent from the leather piece and then transferring the coating consisting of layers of the dressing and finishing composition on to the raw leather piece in a moulding/pressing machine where the coating is heated by high frequency electromagnetic radiation. This overcomes the tendency for the coating to stick to the mould or press and the tendency for the decomposition or deterioration of the coating composition which sometimes occurs in externally heated presses.

Patent DE-3727511-A1 (DE)
Inventor: LAUTENSCHLAEGER JUN KARL
IPC: B22D17/00
Filed: 1987-08-18
Abstract: A tandem diecasting machine (10) for processing fusible metals comprises a closing unit (12) arranged on the machine frame which accommodates horizontally spaced two diecasting moulds (16; 18). Each diecasting mould comprises two half-moulds (16a, 16b; 18a, 18b) separated in a vertical plane. One half-mould (16a, 18a) of each pair is connected to the closing unit and the other half-moulds (16b; 18b) can slide horizontally in opposite directions, which enables the diecasting moulds to be opened and closed. The machine also comprises an injection unit (14) in which the metal to be processed is stored in the molten state. The metal can be fed in metered quantities by an injection cylinder to a nozzle (36) which can be connected to the closed diecasting mould (16; 18). The inlet channel of the diecasting moulds (16; 18) is arranged on the interface between the half-moulds, and the entire closing unit (17) can be moved horizontally in the longitudinal direction between two terminal positions in which the interface of the two half-moulds in a diecasting mould (16 or 18) is aligned with the nozzle (36) of the injection unit (14). The closing unit (12) and the injection unit (14) can move relative to each other, transversally or longitudinally, between one terminal position in which the injection nozzle (36) is pressed hermetically against the inlet channel of one of the diecasting moulds (16 or 18) and a second terminal position in which the nozzle (36) is separated transversally from the diecasting moulds (16; 18).

Title: Motor-driven electric tool
Inventor: VOEGELE ROLAND DIPL ING
IPC: B24B23/04
Filed: 1987-08-25
Abstract: In known motor-driven electric tools, the tool is set in an oscillating movement by means of a roller eccentric, attached to the output shaft, and a guide link. The tool is in this case arranged on a special oscillating shaft which is multiply supported and runs parallel to the output shaft. Such a construction takes up a lot of space and is structurally complex. The new drive for producing an oscillating movement of the tool is, in contrast, to be of simple design, take up less space and be suitable, moreover, for receiving various tools. To achieve the said aim, the link is constructed as a plate (15) which is provided with a cutout (14) for receiving the roller eccentric (12, 13) and is mounted on a pin-shaped extension arm extending spatially at a distance above the output shaft and parallel to the latter and serves as support for the tool (Fig. 1). <IMAGE>
Patent DE-3732915-A1 (DE)
Title: Circuit arrangement for automatically setting the quiescent current in a push-pull output stage
Inventor: SCHMITZ FRIEDRICH
IPC: H03F1/30
Filed: 1987-09-30
Abstract: The quiescent current in a push-pull output stage is set automatically by a sensing element being provided in each branch of the output stage. The two voltages, measured with respect to reference potential, on the sensing elements are passed to a differential amplifier stage whose output voltage is compared with a reference value, with the aid of a comparator. The circuit exhibits frequency dependency on the automatic quiescent-current regulation, as a result of the cut-off frequency of the output transistors used. In order to avoid this frequency dependency, a phase-shifting element is connected to one input of the differential amplifier, which element results in the common-mode rejection of the differential amplifier deteriorating at high frequencies. This measure results in the frequency-dependent error being compensated for. Push-pull output stages having quiescent-current regulation. <IMAGE>

Title: Accumulator for electric tools and similar appliances
Inventor: KLUCK JENS DIPL ING
IPC: H01M2/10
Filed: 1987-10-09
Abstract: In the case of battery-powered electric tools, the accommodating chambers for the accumulator are frequently of different dimensions, even when said accumulator is designed for the same voltage and the same capacity. This leads to an uneconomic multiplicity of accumulator designs in one voltage range. The new accumulator is intended, as a basic unit, to satisfy the precondition for installing it in accommodating chambers of different volume. In order to create this precondition, the cross-section of the housing (12) of the accumulator is essentially constant except for the base region, and the base (14) has a flange-like expanded region (15) which is used as a stop surface for various types of adaptor components (21, 32, 41), which can be fixed to the accumulator housing (Figure 5). By combining it with adaptor components as desired, the accumulator is suitable for insertion in accommodating chambers of very different electric tools. <IMAGE>
