Title: Container for temporary storage of radioactive articles - embedded in plastics esp. polyurethane foam for later recovery
Inventor: ANTON RUDOLF
IPC: G21F9/36
Filed: 1980-12-17
Abstract: A container for storing, esp. temporarily, radioactively contaminated articles or radioactive solids of medium to low activity contains these articles or solids in a matrix of foamed, solidified plastics, esp. a plastics which is not easily flammable and has closed pores. Pref. material for the matrix is polyurethane foam. The container may comprise a barrier preventing the escape of radioactive substances. Used partic. for temporary storage of radioactive articles and substances which must subsequently be recovered for further treatment (not particularly for radioactive waste disposal in the final form). The foam is more easily removed than a bitumen or concrete matrix but does prevent the articles from moving about inside the container and causing possible damage. Foam is also suitable for light articles which tend to float to the top of the bitumen or concrete. Typical articles include contaminated laboratory equipment, lead shielding for radioactive preparations, components of wood, tools etc.

Title: Rodless deep-drilling apparatus
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: E21B10/26
Filed: 1981-04-01
Abstract: The deep-drilling apparatus described here came from the coaxial type of active, media-free inertial rudder which here serves as a deep-drill high-moment drive. The gyroscopic driving axis and the output axis are coincident and a multiplicity of drive elements of small diameter are coaxially layered lengthwise in a moment-adding pot provided with internal slots which adds the individual moments for the drill-drive moment. The individual rudders have locking mechanisms, two per section, which are arranged coaxially to the output axis in their housing plates and, in addition to the sin<2> phi  rectifier principle of the earlier inertial rudders, rectify the gyroscopic moments. With an inner coupling via slot and key, the actual pot-shaped drilling head is interchangeably pushed over the adding pot and it has, for example, front drill bit edges for hard rock and/or peripheral cutting and upward-reaming profiles wound thread-like.

Patent DE-3147287-A1 (DE)
Inventor: EBNER WALTER
IPC: B23P5/00
Filed: 1981-11-28
Abstract: An apparatus and a process are disclosed making it possible to mount, without disadvantages, relatively hard particles, such as diamond dust and the like, on wire-like base material in such a way that the diamond dust is not damaged, wherein any desired coating, that is, especially also a coating coherent over the length of the wire, can be produced. This coating is at least macroscopically homogeneous in character. In such a process for the application of relatively hard particles to a circular wire-like form or a wire-like form without longitudinal edges, for the purpose of producing a plain or multiple saw, the form is coated under pressure with the aid of a surface of two rolls. This surface is at least partially provided with the particles to be applied. The wire-like form is turned about its longitudinal axis during this process. The form must be present in the straight, that is stretched, condition. The process can be performed with an apparatus exhibiting two hardened and ground rolls movable relatively to each other. These rolls serve for the accommodation of hard particles and the form to be coated, and for rolling the form between the two outer surfaces of the rolls. The to and fro movement for rolling the form takes place mechanically.

A passage (78) starting in the drawing above the control valve (47) in the stepped bore (43) intersects the passage (76), which leads radially into the first pressure space (21). At the radially outer circumferential surface of the control valve (47), a sealing sleeve (68) is fastened in an annular groove (67). The sealing sleeve (68) forms the first non-return valve opening from the refilling tank to the filling or pressure space (14 or 21). Formed between the valve (95, 76) and the end of the filling space (14) is a sealing ring (81) which is in sealing engagement with the piston surface of the smaller piston step of the stepped piston (4) and the associated bore section (7) of the housing (2). <IMAGE>

Title: Active audio-frequency low-pass filter arrangement
Inventor: BITAR OMAR DIPL ING
IPC: H03H11/12
Filed: 1982-08-27
Abstract: An active audio-frequency low-pass filter arrangement is described, the characteristic of which follows a particular prescribed curve and which outputs an undistorted output voltage of up to 95% of the maximum output voltage. The filter arrangement exhibits a series circuit of an amplifier (13), a vessel filter (14) and a Tchebysheff filter (15). From a certain frequency onward, the amplifier has a steeply rising gain, the vessel filter has a steeply increasing attenuation from the certain frequency onward and the Tchebysheff filter has such a characteristic that the sum of the characteristics results in the required characteristic (4). The steep increase in attenuation of the vessel filter from the certain frequency onward is required for achieving a small step response of the Tchebysheff filter. The characteristics of amplifier and Tchebycheff filter are used for compensating for the steep increase in attenuation of the vessel filter. <IMAGE>
