Title: Pebble bed reactor side reflector as boundary to hot gas header - comprises tall graphite blocks in this zone to resist pressure difference
Inventor: ELTER CLAUS DR
IPC: G21C11/06
Filed: 1980-12-19
Abstract: A hollow cylindrical (annular) side reflector for a nuclear reactor, esp. gas-cooled nuclear reactor with a core composed of spherical fuel elements (pebble bed reactors) is composed of graphite blocks dowelled and keyed together and comprises an inner and outer cylinder (3;2). The side reflector surrounds a bottom reflector supported by columns from the bottom plates and itself is vertically supported from below. The space below the bottom reflector and above the bottom plates constitutes the hot gas collecting chamber or header and is radially bounded by the side reflector. The side reflector has radial struts bearing against the side thermal shield or liner. The graphite blocks (15,16) of the inner and/or outer cylinders of the reflector are higher in the region of the hot gas collecting space (14) than the height of the hot gas collecting space (14) itself. Where the side reflector constitutes the outer boundary to the hot gas header below the bottom reflector, it is subjected to appreciable loading due to the pressure difference between this header space and the annular space outside. Where the reflector wall in this zone is composed of keyed and dowelled graphite blocks, this imposes limits upon the allowable pressure difference. By using taller graphite blocks to construct the reflector in this zone, the pressure difference can be greater. The inward radial force on the reflector blocks in this zone can be transmitted to the bottom reflector and bottom support plate.

Title: Stencil for the squaring of a circle
Inventor: KUHN HUGO
IPC: B43L13/20
Filed: 1981-01-17
Abstract: With this stencil, the squaring of a circle can be achieved graphically with the accuracy of the pi ( pi ) number. The stencil contains the line radius r times pi as a quarter circle of radius 2.r and the Thales circle via the line radius r plus radius r times pi. According to the height theorem: a square is equal to radius r times radius r times pi. Thus, a = r  pi . Moreover, the stencil contains a bevel with the angle alpha ( alpha ). Tangent alpha is equal to a divided by r. Thus, tan  alpha  =  pi . By means of this bevel with the angle alpha, for a radius r<*> plotted as the abscissa the corresponding value for a<*> can be drawn as the ordinate. The area content of the circle of radius r<*> is equal to the area content of the square of side length a<*>. This stencil for squaring the circle could be used in geometry as a drawing instrument by school children.   <IMAGE>

Title: Method for determining the instantaneous drift value of a course gyro
Inventor: ROGGE JOACHIM DR ING
IPC: G01C19/34
Filed: 1981-04-15
Abstract: It is known that course gyros have the unpleasant characteristic of changing their spin axis alignment, that is to say they drift. The drift of such a gyro is composed of a latitude-dependent known component and a gyro-dependent unknown component. To compensate for the latter, when the gyro is carried along in a vehicle, the drift is measured when the vehicle is stationary. The invention proposes a method for how the vehicle stop can be recognised only from the gyro signals. For this purpose, it is proposed to continuously measure the changes in gyro alignment in short time intervals but not to include the changes in the gyro drift determination when the difference of two measurements, which are apart by a predetermined time  DELTA T, exceeds a predetermined value  DELTA ,  DELTA T and  DELTA  being selected in such a way that the difference  DELTA  cannot be exceeded within the predetermined time  DELTA T with a predetermined maximum drift of the gyro. <IMAGE>

Title: Method for storing densifiable radioactive waste materials (substances)
Inventor: BAATZ HENNING DR
IPC: B09B3/00
Filed: 1981-07-29
Abstract: The invention proceeds from a method for storing densifiable radioactive waste materials. The waste materials are densified, the densified waste materials are accommodated in standardised storage drums made from sheet steel, and the filled storage drums are stored in storage sites, in particular in underground storage sites. In this case, the waste materials are filled into auxiliary drums made from steel sheet. They are densified with the auxiliary drums to form moulded steel shell articles. In each case, a plurality of the moulded steel shell articles are accommodated in the storage drums, which are thereby simultaneously stiffened. The result is that the radioactive waste materials no longer lie freely in the waste drums, that the storage drums are reinforced, and that substantially larger quantities of radioactive waste materials can be accommodated in the storage drums and thus in the storage sites. <IMAGE>

Title: Measuring device for testing the tooth profile and, if necessary, the tooth bevel (angle of tooth)
Inventor: HOEFLER WILLY DR ING
IPC: G01B5/20
Filed: 1981-08-29
Abstract: The invention relates to a transportable measuring device for testing the tooth profile and, if necessary, the tooth bevel. This measuring device must be levelled with regard to the toothed wheel to be tested in order that the plane coordinate system assigned to it is perpendicular to the toothed wheel axis. In addition, the measuring device is to be aligned relative to the toothed wheel such that one axis of its coordinate system intersects the toothed wheel axis. According to the invention, for this purpose the measuring device has two axially parallel fitting cylinders which are arranged on both sides of and equidistant from the coordinate axis to be aligned radially relative to the toothed wheel. In order for the alignment not to require any relevelling of the measuring device, the latter is arranged adjustably on its base which carries the supporting feet, specifically either by means of a tangential carriage or by means of a swivel bearing. The measuring device can accordingly be brought simply and quickly into the desired reference position relative to the toothed wheel.

Title: Control device for detecting a shopping trolley consisting of ferromagnetic materials
Inventor: HAUGK ANDREAS DIPL ING
IPC: G08B13/24
Filed: 1982-05-13
Abstract: The invention relates to a control device for detecting a shopping trolley, consisting of ferromagnetic materials, at a checkout. The detection of the shopping trolley is performed by a magnetic barrier and a reflected light barrier, specifically in such a way that when a shopping trolley is pushed up to a checkout the light beam of the reflected light barrier is interrupted. This causes a signal which is initially fed to a goods search device. When the shopping trolley is pushed further forward, the magnetic field of the magnetic barrier is influenced, as a result of which a further signal is produced which is likewise fed to the goods search device. Not until the arrival of both previously mentioned signals is the goods search device activated and the shopping trolley thus unambiguously identified as such. Due to the combination of magnetic and reflected light barriers in conjunction with a goods search device, this device according to the invention for detecting shopping trolleys at checkouts provides a control device which avoids the disadvantages of the known devices, on the one hand, and reliably identifies even dirty shopping trolleys, on the other hand.
