Title: Neutron flux detectors esp. for gas cooled reactor - are contained in retractable tube inserted through pressure vessel wall into fixed gas-tight tube
Inventor: ELTER CLAUS DR
IPC: G21C17/108
Filed: 1980-11-06
Abstract: An apparatus for measuring the neutron flux distribution in a nuclear reactor, esp. a gas-cooled (typically high-temperature) reactor, comprises a fixed pipe, which is seal-welded to the reactor liner (on lower face of pressure vessel top closure) and penetrates down through the core and has a closed end at the bottom inside this fixed pipe which constitutes the gas pressure boundary there is mounted a retractable guide tube which contains a number of detectors and a rod. The guide tube itself may be made up from a number of lengths of tube connected end to end and similarly the rod may be made up from a number of lengths, connected together by cylindrical pins. Where the guide tube crosses through the liner tube in the top of the pressure vessel, there are inner and outer shielding plugs. The flux detectors can be easily removed at any time during the life of the reactor, since the outer, closed tube constitutes a permanent pressure boundary and access can be gained into t from the top end.

Title: Screw connections in concrete for vertical extraction forces and/or horizontal forces
Inventor: SCHNABEL WINFRIED DIPL ING
IPC: E04B1/41
Filed: 1981-01-14
Abstract: The invention relates to an anchorage for steel structural components, which is mounted retroactively by screw connection, on concrete parts, is inserted into the concrete during the concreting of these concrete parts and has to absorb vertical extraction forces and/or horizontal forces. The object is achieved according to the invention in that a washer and a heat-treated screw nut are arranged at the lower edge of a steel tube of any desired length. The screw nut and the washer are encased in plastic and non-positively connected (Fig. 3) to the steel tube, e.g. by a tube connection attached to the plastic casing. Steel structural components can be screwed onto concrete parts with prestress by a screw bolt screwed into the screw nut. As a result of the prestressing force between the steel structural component and the steel tube, horizontal forces can be transmitted, by way of friction, to the steel tube and from there to the concrete. Vertical extraction forces are conducted from the screw nut into the concrete by way of the steel washer. Anchorages comprising a plurality of screw connections are connected at predetermined distances from one another by spacers. <IMAGE>
Patent DE-3103421-A1 (DE)
Inventor: KLEMM GERHARD ING GRAD
IPC: B41F15/12
Filed: 1981-02-02
Abstract: A screen printing machine has at least one printing station wherein rotary or flat screens are used. Downstream of the printing station, there is provided a heated continuously or discontinuously driven roller over the heated jacket of which the web is trained. The web preferably consists of impermeable material. The heated roller defines a drying path. A cooling unit is disposed downstream of the drying path and is preferably defined by a cooling roller which is connected to a cooling device. A web supplying roller is mounted at the inlet of the machine and a takeup roller is mounted downstream of the cooling unit. The transport of the web may be controlled during forward movement as well as during rearward movement. The machine is compact because the cooling unit and one of the web supplying and takeup rollers are disposed at a level below the printing station. During intermittent operation, the heated roller operates in two stages, with a main stage and a follow-up stage both controlled by a device for imprinting and reading passer markers.
Patent DE-3107163-A1 (DE)
Title: Projector for writing foils and opaque originals
Inventor: WANNERT MICHAEL
IPC: G03B21/132
Filed: 1981-02-26
Abstract: The invention relates to a combination projector which is equally suitable for writing projection and episcopic projection. It is the object of the invention to save production costs and invent a practical, didactically sound projector. The invention is characterised in that the two projection processes require only one lens which is attached to a swivellable column (1). Attached rotatably to the projection head is a mirror which is swivelled upwards by a weight, thereby clearing the beam path, when the column (1) is brought into the episcopic position. At the same time, the illumination is switched over by the nose (15), and a lever (18) presses the adaptor tube (8) via the leaf spring (17) against the projection head, while the shutter (19) clears the beam path. When swivelling back takes place, the weight presses the mirror against a setting arm, so that the mirror setting corresponds in the case of writing projection to the initial position. The advantages reside in a very good price/performance ratio, since in each case only one lens, cam shaft, motor and transformer are required. Manipulation is easier than when two projectors are used. <IMAGE>

Title: Screw nail
Inventor: TRURNIT FRIEDRICH WILHELM
IPC: E04D3/36
Filed: 1981-02-27
Abstract: In the case of a screw nail for fastening heat-insulating panels or the like on a sheet-metal substructure, the drive-in end is formed with a coarse thread which is overlaid with annular grooves with sharp-edged outer groove webs. The steel shank is coated with a plastic sheathing which is adjoined at the top by a disc-like plastic head. The external diameter of the drive-end is greater than the diameter of a smooth shank portion provided between drive-in end and the plastic sheathing. The screw nail is double secured in a sheet-metal substructure by means of such a configuration of the drive-in end. The coarse-threaded end overlaid with grooves engages particularly strongly on the hole borders formed. The step between the threaded end and the smooth shank portion prevents, once the nail has been driven through by this drive-in end, the nail from being drawn out from its substructure unintentionally.

Title: New system for delivering water from wells, boreholes, water basins and water courses and other water sources without the use of conventional centrifugal pumps with impeller wheels or piston pumps, which were driven by motors
Inventor: MARES JOAN
IPC: F04F1/08
Filed: 1982-01-21
Abstract: The system for delivering water from wells, water basins or water courses comprises a vessel (1b) to be immersed in the water, into which vessel water can penetrate by way of a non-return valve (3). The vessel (1b) is connected by way of a compressed air line (13) having a controllable valve (11) to a compressed air source. In addition, a hydraulic main (5) leads from the bottom area of the vessel (1b) to the points of use. The water is delivered in that, when the vessel (1b) has partially or completely filled with water, this is is forced by the supply of compressed air to the vessel (1b) into the hydraulic main (5). The alternate venting and admission of compressed air to the vessel (1b) can be performed by means of a float (8) carried in the vessel, which float acts on a reversing valve (11). In tandem construction, two vessels can be immersed in the water and subjected to compressed air alternately, it being possible to lead the compressed air line (13), the venting line (12) and hydraulic main (5) of the one vessel through the other. <IMAGE>
Patent DE-3205460-A1 (DE)
Title: Contactless, feedback-free temperature measurement using permanent magnet, calibration curve and Hall generator
Inventor: GRASER MARTIN
IPC: G01K7/36
Filed: 1982-02-16
Abstract: The aim is temperature measurement in/at/on rotating or oscillating components to which because of rapid translation or rotation it is impossible to apply connections from the sensor to the measuring device. This method enables graphic or digital display of the temperature from hermetically sealed rooms or through walls. In this arrangement, a magnetic effect is exploited, the decrease in remanence with temperature. This decrease in remanence with temperature is programmed graphically retained and used as calibration curve for a permanent magnet of entirely purposeful design (dimension, axial ratio, material) and for a specific distance of the sensor (magnet) from the measuring transducer (Hall generator). The choice of a Hall generator as measuring transducer enables measurement free of feedback, since the energy required for measurement comes from "the measuring instrument". If the calibration curve is available, the temperature prevailing at the sensor can be determined by measuring the remanence for a firstly unknown temperature using this calibration curve. This can be performed manually using the calibration curve in diagrammatic form, or automatically, by computer in the case of a programmed curve. In this case, the measured remanence value is assigned the associated temperature value. By repeated measurement and calculation in short time intervals a digital display of the temperature is obtained.
Patent DE-3210985-A1 (DE)
Title: Contactless electronic control for sanitary fittings, particularly a urinal
Inventor: WERTENAUER HELMUT
IPC: E03D5/10
Filed: 1982-03-25
Abstract: This electronic control operates with radar or microwaves and utilises the doppler effect. In contrast to known controls of this type, it has a so-called dual module having two mixing diodes which have a certain geometric distance from one another. The output signals of these two mixing diodes have a characteristic phase relation depending on whether the user is approaching the urinal or moving away from it. The signals are processed by a phase discriminator which generates a first output signal (A) which indicates an approach of the user, and a second output signal (E) which means that the user is moving away. In this manner, much more information is obtained on the movement of the user in front of the urinal so that mistriggering and wrong flushing can be avoided. The two signals (A and E) can be processed further in a variety of logic manners. <IMAGE>

Title: Taper clamping arrangement with auxiliary ring
Inventor: MUELLENBERG RALPH
IPC: F16C35/073
Filed: 1982-04-27
Abstract: A taper clamping arrangement for connecting a hub to a shaft. It comprises tapered elements which can be displaced axially relative to one another via a tapered surface by means of clamping screws, are designed as taper rings or taper discs and both have axial threaded holes which open towards the same side. Mounted on this side, in front of the threaded holes of both interacting tapered elements, is an auxiliary ring which has a different configuration on the two sides due to the formation of a collar in front of only one tapered element. The collar can be made integrally on the auxiliary ring or consist of a separate element. In the two work phases, "clamping" and "release", the auxiliary ring presents different axial bearing surfaces to the tapered elements, as a result of which it can be both clamped and released by means of the clamping screws, which can be screwed on the one hand into one tapered element and, on the other hand, into the other, and the clamping screws are in both cases under tension. <IMAGE>
