Title: Device for aerating water, particularly waste water
Inventor: JAEGER ARNOLD
IPC: C02F3/20
Filed: 1982-05-15
Abstract: The invention starts from devices of this type in which perforated supporting tubes are provided for introducing the air, on which finely perforated rubber sleeves are arranged. While in the case of known devices a supporting tube was assigned to each sleeve, according to the invention one supporting tube is installed for a plurality of sleeves, so that the air can thus be introduced at one end or at both ends of said continuous supporting tube. To be able to make use of greater lengths of said supporting tube, it is flexible so that it can alternatively be installed in coiled or curved shapes.

Title: Pressure-operated switch
Inventor: LUNGU CORNELIU DIPL ING
IPC: H01H35/34
Filed: 1982-07-10
Abstract: A pressure-operated switch (2) is proposed which has a pressure sensor (65, 70) which is sealed relative to its housing (63, 64) and can be displaced in two directions from a neutral position, and has an elastic restoring device, which acts against both displacement directions. The restoring device consists of a pretensioned compression spring (74), two spring plates (72, 73) resting on the ends of said compression spring, and in each case two annular stop surfaces (92, 98; 94, 100) which are directed against each of the spring plates and are arranged concentrically, and of which in each case one (92; 94) is arranged such that it moves together with the pressure sensor and the other (98; 100) is arranged such that it does not move. The pressure sensor consists of a membrane (65) of annular construction and of a pot-like piston (70) which is connected to the inner circumference of said membrane. Accommodated within said piston are the moving stop surfaces, the spring plates, the compression spring and a guide pin (75) which extends through the spring plates. On its circumference, the piston supports electrical contacts (105, 106). As a result of its construction, the pressure-operated switch has a very short dimension in the movement direction of the pressure sensor.

Patent DE-3301750-A1 (DE)
Title: Device for outputting electrical switching pulses for electronic controls for model railways
Inventor: MUELLER HANS-HELMUT
IPC: A63H19/24
Filed: 1983-01-20
Abstract: The invention relates to a device for outputting electrical switching pulses for electronic controls for model railways. For this purpose, two or three contacts which are held by means of an insulating connection in their mutual position with respect to one another at a small distance from one another are arranged right next to the inner edge of a contact rail in the region of the wheel flanges of the wheels. As a result, they can move downwards in a spring-mounted manner out of their position of rest by means of the wheel flange which runs over, the wheel flange itself serving as a pulse-transmitting contact bridge between every two adjacent contacts. As a result, the device is extremely simple and can be used universally so that its cost is greatly reduced. Nevertheless, all the rail vehicles can trigger switching pulses without additional extensions or conversions.

Patent DE-3314581-A1 (DE)
Title: Process for the multiple use of an erasing ribbon and erasing-ribbon device
Inventor: HOTAN JUERGEN
IPC: B41J31/09
Filed: 1983-04-22
Abstract: The invention relates to a process for the multiple use of an erasing ribbon employable for corrections and to an erasing-ribbon device suitable for carrying out the process. Whereas the erasing-ribbon correction device used has hitherto conventionally been a disposable article, the invention leads to a multiple use of the erasing ribbon. In terms of the process, there is used here, on the winding side, an adaptor spool which, after a first run-through, can be rotated about 180 DEG  and is then available as a new supply spool, but with a used erasing ribbon. In terms of the device, the adaptor spool is so designed that it can either serve directly for winding the used erasing ribbon and possesses, in addition to a retention device on the winding side for the transport of the erasing ribbon, a further retention device which is made complementary to the drive device on the supply-spool side. Alternatively, however, the adaptor spool can also receive a spool corresponding, at least as regards the retention device, to the supply spool and serve for securing said spool fixedly in terms of rotation during the winding of the used erasing ribbon. In this case, instead of the adaptor spool, the spool wound in the adaptor spool is changed over by means of a 180 DEG  rotation to the supply-spool side, in order to be available for a new run-through of the erasing ribbon.

Title: Lid for preserving jars
Inventor: POROMBKA KONRAD
IPC: B65D51/16
Filed: 1983-11-29
Abstract: For the purpose of introducing a visual, instead of a manual, control method of the holding capacity of the lid and an opening method which is always easy, instead of not always being easy, for grooved and other preserving jars, the lid is provided, inter alia, in the centre with a venting hole (1) and, around its edge (3), with a groove (4). The venting hole includes a stopper (6, 7) as its reliably tight closure. A lifting spring, belonging to this lid, which is V-shaped in profile and has a resting limb (8) and a hooking-in limb (9) is placed on the pulling tab of the sealing rubber ring prior to storage of the preserving jars and is hooked into the groove of the lid. In the case of loss of vacuum in any jar, said lifting spring raises the lid only slightly, but in a sufficiently well visible manner, into an oblique position relative to the container and thus allows a visual control of the holding capacity of the lid to be carried out. For opening preserving jars, it is sufficient to loosen the stopper in the venting hole, which can always be carried out easily. <IMAGE>

IPC: B28B7/30
Filed: 1984-04-26
Abstract: A retractable core for producing a relatively long casing section, in particular of floor-to-floor height, which can be cast from concrete, preferably from lightweight concrete, of a chimney casing which can be assembled from a plurality of casing sections is distinguished in that a hollow profile which serves as a core and the length and cross-sectional shape of which are equal to the internal cross-section and the length of the casing section to be produced has profile walls which are movable in the radial direction and in that actuatable adjustment elements for the movement of the profile walls are incorporated into the hollow profile. The adjustment elements comprise a shaft extending through the hollow profile eccentric discs arranged eccentrically on the shaft and projecting radially therefrom and a radial arm mounted on each eccentric disc, each of which radial arms is connected with an associated profile wall. With a rotation of the shaft the radial arms pull the profile walls connected to them inwards, reducing the cross-sectional profile of the retractable core.

Patent DE-3427155-A1 (DE)
Title: Wind-driven power station
Inventor: MICKENHAGEN ERNST DR
IPC: F03D5/04
Filed: 1984-07-24
Abstract: The utilisation of the energy of the wind has long been done with the aid of sails. The application to ships requires the sails to be expertly hung with respect to the wind. In order to use wind energy locally, sails have been bound to crosses which have a transverse axis and from which the energy is extracted by belts or toothed gears. Even vanes with large spans and a rapid rate of revolution cover only a small region of the wind blowing onto them. Since each location typically has main wind directions, an elongated system set up high above the ground can capture the wind and use its energy if devices capture the wind and generate electrical power by endless circulation on the system. For this purpose, the present invention connects a circulating way of the type of a cableway, to linear generators which can be switched over to linear motors. Carriages travel on the circulating way which carry Flettner rotors, and mounted on the latter are magnets which interact with the magnetic strips of the way to convert the energy of the wind into current.
