Abstract: A mounting element (10) which consists of a trough-line lower part (11) and a trough-like upper part (12) is used for fastening automatic line protection circuit breakers in electrical installation channels (ducts). Located on each end wall (18) is in each case one cable entry opening (17) which is inclined at an angle of approximately 45 to 60 degrees with respect to the centre plane (9). Terminal strips (23) for the neutral and protective earth conductors are in each case seated behind the cable entry openings (17).

Abstract: An image display apparatus includes an image display device (4) such as, for example, a liquid crystal display panel, having a plurality of dot-shaped picture elements (12) arranged in a two-dimensional pattern, and a diffraction grating (5) disposed on an optical path through which imagewise rays of light emerging from the device (4) travel. To minimize a reduction in quality and contrast of an image displayed by the device (4), the grating(5) has a spatial cut-off frequency (fc) chosen to be of a value lying between the sampling frequency (1/P H ), determined by the pitch between picture elements (12) of the image display device (4), and the Nyquist frequency (1/2P H ). For the same purpose, the intensity of ±1st order light relative to the intensity of 0-th order light in the diffraction grating (5) is within the range of 60 to 80% at a center wavelength of the image display device (4), and the sum of the intensity of the 0-th order light and that of the ±1st order light relative to that of total diffracted light is equal to or higher than 80% at the center wavelength of the device (4).

Abstract: The method for the automatic acquisition and recognition of scripts, using software-controlled reading devices is especially suitable for the acquisition and recognition of handwritten entries and/or machine scripts on receipts and forms, that is to say a mixture of various types of script. The electronic receipt images acquired by means of a special camera device are fed to readers I, II (to N), which operate respectively with different recognition methods, that is to say they have differently optimised reading properties. Characters not recognised by one reader are recognised by the other reader. A correct data set can be generated automatically. If characters are recognised as correct in reader I but are substituted in reader II, this recognition discrepancy leads to a forced checking and correction. Manual processing is significantly reduced by means of this improvement of recognition and undiscovered substitutions are largely prevented. <IMAGE>

Abstract: A transconductance amplifier comprises first and second input transistors (TO1,TO2) to the base electrodes of which an input voltage (Vi) is applied. A constant current source (10) is connected to the emitters of the input transistors. Outputs are derived from their collector electrodes. A tapped impedance having two or more segments (RO to RN,RN to RO) is connected between the base electrodes of the input transistors (TO1,TO2). The base of a further transistor (T1 to TN,TN to T1) is connected to a respective tap (a1 to aN,aN to a1) of the tapped impedance. The emitter areas (e1 to eN,eN to e1) of these further transistors increase from each end of the tapped impedance towards the centre (28) of the tapped impedance. The emitters of the further transistors (T1 to TN,TN to T1) are connected to the current source (10) and the collectors are connected to a junction (26) which is connected to means (30) for computing the combined base currents of the further transistors (T1 to TN, TN to T1) from the combined collector currents at said junction (26). The computed current is supplied by a current mirror circuit (32) to the centre (28) of the tapped impedance to pull up the voltage at the centre (28). The tapped impedance can have an increased resistance without unduly loading a preceding stage.

Abstract: A defect detection system (10) of this invention applies one or more spacially-separated, orthogonally-aligned light beams (22 and 24) to a coated fiber (32) such that the light passes through the entire width of both the fiber (32) and its applied coating (31). As the light passes through a fiber (32) and coating (31) of good quality, a particular pattern, with a predictable intensity level, is produced by the forward scattered portions of the light beams directed through the coated fiber (32). 
     In accordance with the present invention, the intensity of the forward scattered patterns is continuously monitored by a series of photodiodes (48) each located within a lens/detector module (40, 42, 44 and 46) and positioned precisely within the expected forward scatter pattern. Various defects in the coating cause the path of the light passing through the coated fiber (32) to be altered, thereby directing some of the forward scattered light outside the detection area of the photodiodes (48). Such distortion to the forward scatter patterns causes the light intensity level measured at the photodiodes (48) to decrease. Therefore, by continuously monitoring the forward scatter patterns for a reduction of light relative to the light intensity expected, the present invention provides reliable and accurate means for detecting temporally short defects, such as air bubbles, which may be present within the coating (31) of a fiber (32).
