Patent DE-4115604-A1 (DE)
Title: Multiple testing circuitry for electricity meters - compares readings of one or more meters under test with known test performance, current and voltage paths being galvanically connected
Inventor: KAHMANN MARTIN
IPC: G01R35/04
Filed: 1991-05-14
Abstract: The sec. winding (18) of a transformer (17) is connected in series with the resistance (3) of a meter (5) in the current path. The prim. winding (19) is controlled by an amplifier (10), such that a voltage of such a level and polarity is produced at the sec. winding (18) of the transformer (17) that this voltage and the voltage drop at the resistance (3) are just neutralised. The voltage at the sec. winding (18) due to the wiring of the prim. winding (19), takes up the required level and polarity, by the control of the current which flows through the sec. winding (18). ADVANTAGE - Reduces voltage drops in current paths of electricity meter resting units.

Patent DE-4207895-A1 (DE)
Inventor: SCHNEIDER WOLFGANG DR
IPC: B22D11/16
Filed: 1992-03-12
Abstract: The invention relates to a method and an arrangement for the vertical continuous casting of metal in a hot-top mould with equal-level metal feeding. The object on which the invention is based is to provide a method and an arrangement which make it possible, in the case of equal-level metal feeding, to avoid asymmetric temperature gradients, turbulence and unusable metal volume. According to the invention, this object is achieved by the fact that the equality of level of a metal melt in a hot-top mould and at the outlet opening of a melting furnace is produced by means of a launder (1) which is passed through the upper region of the hot-top mould and, by means of outflow openings (10) in the side walls, establishes a connection with the metal melt in the hot-top mould, the bottom of the launder (1) lying in a plane below the level of the outlet opening of the melting furnace and below the upper edge of the hot-top mould. <IMAGE>

Title: Method for examining multidimensional nonhomogeneous structures
Inventor: BILZ DIETRICH DR
IPC: G01N21/47
Filed: 1993-02-03
Abstract: The invention relates to a method for examining multidimensional nonhomogenous structures, the respective volume elements being determined on a point basis differentially in the z direction of the radiator or the transmitting elements, specifically by using transmitter/receiver matrices which have structures with large surfaces and consist of a number of transmitter/receiver elements. The transmitter and receiver elements are arranged in a plane and designed as a flat matrix or line. The transmitter/receiver elements form extremely small units in which the transmitter and receiver can be actuated or read out separately. The transmission intensity and wavelength of the transmitter elements can be varied or else also kept constant. By successive irradiation in a circle around the detector or detectors or by successively moving the transmitter elements around in an annular shape using the multiplex method, the stray light intensity focus which arises with simultaneous annular-surface irradiation in the depth of the structure to be examined is detected in a defocused way and the volume element located there is tomographed.

Title: Hollow roller - has internal heating for mantle width covered by web material without heating uncovered edge zones
Inventor: STEINER KARL DR
IPC: D21F3/08
Filed: 1993-03-31
Abstract: The hollow roller body has internal heating system which is adjusted across the roller width so that the heating action is applied only to the roller mantle across the width of web being processed, without heating uncovered roller edge zones. Pref. external heat is applied to the roller mantle, at the edges of the web material passing round the roller, for the roller mantle temp. to be set simultaneously by external and internal heating. The internal and external heating systems are positioned so that they overlap partially. The inner heating has sectors which can be activated as required, as has the external heating system. The external heating system can be moved axially parallel to the roller. USE/ADVANTAGE - The roller is esp. for papermaking and other machines for the prodn. of continuous web materials, as smoothing rollers, pressure rollers or drying cylinders and the like. The system restricts the heating effect to the roller width covered by the web material, to prevent the roller edges from expanding into undesired oxbow shape.

Title: Apparatus for the non-cutting shaping of a workpiece
Inventor: GRUBER HEINZ
IPC: B23Q11/10
Filed: 1993-04-28
Abstract: To increase the passage speed in a continuously working apparatus for the non-cutting shaping of a workpiece (1), it is proposed to accommodate a rolling device (6) in an essentially closed housing (2) completely filled with a fluid bath. The fluid bath consists of a mineral oil and is kept at a constant temperature via a pipeline circuit which, apart from a heat exchanger (7), has a pump (9) and a tub-like vessel (10) at least partly surrounding the housing (2). On account of the intensive, in particular defined, cooling of the tool of the shaping unit in combination with the guarantee of a stable lubricating film between the tool and the workpiece (1), a substantial increase in the passage speed and in the service life of the tool compared with known apparatuses can be achieved, in which case a certain corrosion protection of the finished workpiece (1) can be obtained at the same time in particular in combination with additives to the mineral oil. <IMAGE>
