Title: Method for the use of burnt-out fissionable reactor fuels
Inventor: GAISER HERBERT
IPC: G21D9/00
Filed: 1988-06-09
Abstract: A method serves for the use of fissionable reactor fuels burnt out in nuclear power stations in the form of rods, spheres or the like. So that intermediate or final storage of burnt-out fuel elements is made superfluous in the next few years by means of a method of this type, and the necessary later final storage of the reactor fuels is considerably simplified, the fuels burnt out in primary nuclear power stations are used as reactor fuels in secondary nuclear power stations which work with the normal nuclear power station steam processes for generator drive and/or with analogous processes for the preparation of hot process water.

Title: Gearshift device for an automatic transmission of a motor vehicle
Inventor: STEHLE HEINZ DIPL ING
IPC: B60W30/18
Filed: 1988-09-29
Abstract: A gearshift device for an automatic transmission of a motor vehicle, controlled by an electronic control module, has a selector lever to be operated manually. The various transmission gears can be selected by swivelling the selector lever in a first selector plate slot. After shifting the selector lever into a second selector plate slot by way of a transverse slot it can be used to manually select the desired forwards gear. The changeover process is sensed by means of a sensor, which influences a changeover unit. The changeover unit causes a currently engaged transmission gear to be retained when the selector plate slot is changed.

Patent DE-3835798-A1 (DE)
Title: Pressing mould, in particular for producing tiles, crockery, plates or the like from ceramic or similar materials
Inventor: MANTEGANI ENZO
IPC: B28B13/02
Filed: 1988-10-20
Abstract: The preferably vertically operating pressing mould has at least one upper ram (34) and one lower ram (35), which rams cooperate with a female mould (32) in which the upper ram (34), connected to the movable crossmember (13) and the pressing piston (8), together with a positioning device (19, 20, 21) of adjustable stroke, determines the thickness of the granules, which have not yet been pressed, in the mould volume (54) of the female mould (32). The female mould (32) suspended on the crossmember (13) is formed by plates (33) which define the peripheral profile of the pressed items (72). A lower ram (35) is fixed essentially in mirror image to the upper ram on the underframe (1) of the press and has vertically extending bores (55, 56) which are connected to a suction pump (38). As a result, the filling operation of the mould volume (54) is accelerated. The female mould (32) determines the filling of the granules, their thickness, the pressing operation, the ejection of the pressed items, and the transfer onto a conveyor belt (77). The invention considerably facilitates both the pressing mould and the press actuating the latter since loading carriages, hydraulic ejectors, braking systems for the movable crossmember, rapid filling and emptying of the pressing cylinder, pressure intensifiers, mechanical positioning systems for the movable crossmember and the like are not required. According to the invention, the movable crossmember carries out a stroke of only a few millimetres which ... the height difference between ... Original abstract incomplete. <IMAGE>

Title: Holographic tomography using 3 D X-ray images (exograph)
Inventor: SCHULZ RUDOLF ING GRAD
IPC: A61B6/02
Filed: 1988-12-08
Abstract: Holography nowadays has many characteristics of an interdisciplinary field of knowledge. The experimental possibilities which holography presents affect areas of application which are remote from fundamental physical-optical research. It is therefore all the more important to expand this technology in particular also to the medical sector. A method is described which makes it possible to construct a hologram synthetically by means of conventional X-ray images. In two steps it will be shown how an image can be created which exhibits three-dimensional correlations. During reconstruction it is possible to select layers of any desired depth. There is a particularly advantageous effect if the X-ray source moves in a circle (circular path) during the exposure: As a result, the often disturbing granulation (crystallisation) is reduced considerably ... a criterion is furthermore obtained for setting a specific depth in the object. The same methods which, because of their importance, have been shown here using the example of medical X-ray images can also be applied to any incoherent recorded picture originals (image originals).

Patent DE-3842411-A1 (DE)
Inventor: ROSENBERGER WINFRIED DIPL ING
IPC: H04N5/60
Filed: 1988-12-16
Abstract: With the introduction of digital television sound in accordance with the NICAM system, the problem arises of constructing a processing unit which ensures that both the digital audio signal and the analog audio signal can be processed. According to the invention, this is achieved by the fact that in the television set a NICAM decoder unit is installed which automatically detects whether a digital audio signal according to the NICAM system and/or an analog audio signal according to a conventional method is present. This NICAM decoder unit automatically switches over to processing a digital audio signal or an analog audio signal and indicates whether a stereo, mono- or bilingual transmission is being received. Furthermore, this decoder unit can be installed not only in new developments but is also suitable for subsequent installation into older television sets. Television sets, particularly television sets with stereo sound. <IMAGE>
