Inventor: MEINL RUDOLF DIPL PHYS
IPC: G21C7/103
Filed: 1992-08-21
Abstract: In a control column in which an absorber element (AE) is coupled to the head of a fuel element (BE) via a coupling component (CE), the region between the lower edge (HA) of the absorber (26) in the absorber element and the upper edge (HF) of the fuel in the fuel rods (7) of the fuel element has an absorber material (15, 32) which extends virtually throughout the entire coupling component. In the fuel element there are absorbing stubs (15) for this purpose which extend through the cover plate (6) of the fuel element and engage in the interstices between the fuel elements (7). The appropriate absorber element has a hollow cylinder (32) which is surrounded by coupling components (30, 31). This prevents the occurence of power distortions which can be produced during the operation of a reactor if the top (HF) of the fuel abuts a region which contains no fuel from the fuel element and as yet no absorber components of the absorber element.

Patent DE-4306723-A1 (DE)
Title: Rotary internal combustion engine
Inventor: MARTIN THOMAS
IPC: F02B53/02
Filed: 1993-03-04
Abstract: This relates to a rotary internal combustion engine with rotor rotating in a fixed housing and at least one intake and exhaust port for the charge cycle. The rotor has two rotor parts which are capable of rotating in opposition to one another between stops on the rotor parts. Between the rotor parts two combustion chambers, variable in their volume during rotation and successively passing through an ignition point fixed to the housing, are respectively formed diametrically opposite one another together with two spring chambers for the accommodation of spring-elastic elements, which hold the rotor parts together in a first stop position for ignition of the gas mixture in the one combustion chamber. The first rotor part is capable of rotating solely in one direction. The second rotor part has a flywheel mass so that, as the first rotor part turns, the second rotor part, as a result of the gas pressure in the first combustion chamber passing through the ignition point, initially remains in its position and as the compression of the spring-elastic elements increases is rotated into a further stop position for an ensuing driving movement of the now stationary first rotor part.

IPC: B23B31/107
Filed: 1993-05-12
Abstract: The fixture units are provided for the five- and multi-sided machining of several workpieces in one set-up on CNC machine tools. The work holder 11 is radially fixed in the hydraulic centring, clamping, dividing and indexing device 33, drawn axially against the flat face and clamped at the shank. In order to completely machine workpieces from five or more sides, several operations and set-ups were necessary with conventional clamping means. The defect rates increased due to the repeated loading and re-setting. In addition, setting, execution and holding times as well as production and final manufacturing costs increased considerably. Fig. 1 For use on CNC machines, the hydraulic centring, clamping and dividing devices 33 are fitted, for example, in a parallelepiped block 10 which is mounted between a rotary table 42 and a counterstay 49. For the machining, the parallelepiped block 10 can now be swivelled through any angle, or the work holder 11 in the hydraulic centring, clamping and dividing device 33 can be turned circularly with an appropriate turn tool 32 by the machine movement at the rotary pin by any graduation number or an angular degree which can be multiplied according to the spacing of the prismatic recesses. After the machining is complete, the preset work holders 11 can be inserted and exchanged manually by the machine operator or in an automated manner by means of robots. <IMAGE>

Title: Arrangement for the high-resolution analog/digital conversion of signals having different signal amplitudes
Inventor: REIS JOHANNES DIPL ING
IPC: H03M1/18
Filed: 1993-07-07
Abstract: The invention relates to an arrangement for the analog/digital conversion of analog input signals having a different signal amplitude, comprising an analog/digital converter and an attenuation element, the attenuation of which is variable. In the analog/digital conversion of signals having different amplitudes, the best resolution for these signals is achieved when the signal amplitude is matched to the extreme range of the analog/digital converter or vice versa. The object of the invention is to specify an arrangement for the analog/digital conversion of analog input signals which has a simple structure and ensures reliable matching of the input signal amplitude to the extreme range of the analog/digital converter. This is achieved by a circuit arrangement which regulates the attenuation required for optimum modulation of the analog/digital converter on the basis of the evaluation of an attenuated input signal.

Patent DE-4334901-A1 (DE)
Title: Grate cooler
Inventor: ZIMMERMANN HORST
IPC: F27D15/02
Filed: 1993-10-13
Abstract: If an intermediate crusher is integrated in a grate cooler, in particular in a thrust-grate cooler for cooling hot material, such as, for example, hot cement clinker coming out of a rotary tubular kiln, this requires a grate stage, e.g. 1.5 to 2 m high, arranged between the front and rear cooling grates. But in known grate coolers this grate stage undesirably increases the overall height of the grate cooler and thus of the foundation heights of the upstream units such as rotary tubular kiln, calcinator, cement-raw-meal heat-exchanger tower. In order to minimise the overall height of such a grate cooler despite integration of an intermediate crusher, it is proposed according to the invention to arrange dust-collecting funnels (17, 18, etc.) known per se in the cooler area up to the cooling-grate stage (13) between the cooling-grate underside and the at least one dust-conveying member (20) located underneath it, but on the other hand not to arrange dust-collecting funnels under the cooling grate (15) in the cooler area from the cooling-grate stage (13) up to the cooler end, but to arrange the at least one dust-conveying member (20) right below the cooling grate (15) and to pass it directly through the air chambers at this location by the creation of labyrinth sealing gaps. <IMAGE>
