Abstract: Apparatus for generating pseudo-random bit patterns that are applied to a data processor, or other digital logic unit, for test purposes. Certain of the elemental storage units (80) (e.g. flipflops) of the data processor are designed for two-mode operation: a normal mode of operation during which they operate as a part of the data processor in normal fashion, and a scan mode operation during which the elemental storage units (80) respond to scan control signals to form a number of shift register or scan line configurations (14) for receiving the pseudo-random sequenced or non-random sequenced test patterns generated by the apparatus. During testing, the bit patterns are passed through the scan line configurations (14) and applied to compression circuits where, using cyclic redundancy checking (CRC), compression bit patterns received from the scan lines are achieved. Test signatures are produced that are stored in a memory for later comparison with standardized signatures to determine the PASS/FAIL condition of the processor. Tests can be preceded and followed by a controlled scan of the digital logic to save and restore the operations state of the digital logic. In this manner, test interruptions are relatively unobtrusive and essentially transparent to the logic tested.

Abstract: The rectifier circuit is universally suitable for connection to a DC or AC network and is particularly suitable for multi-system rail vehicles. In this case, the circuit operates with an AC supply as a four-quadrant adjuster and with a DC supply as a step-up or step-down series circuit. The circuit has four arms in a bridge circuit, each arm consisting of a valve (T1...T4), which can be switched on and off, with an anti-parallel, uncontrolled rectifier (D1...D4). Between the connections (F,G) on the DC side of two arms of equal polarity (T1/D1/T3/D3), a switch contact (17) is provided. When the switch contact (17) is open, the supply from the DC network passes through the DC connections (D, E) of the rectifier, whereas the AC connections (A1, B1, A2, B2) are short-circuited. To supply the circuit from the AC network, the switch contact (17) is closed. <IMAGE>

Abstract: Flyash-containing flue gas from a conventional fossil fuel fired boiler plant and/or flyash separated in the flue gas filter of the plant is admixed with ground, dry limestone (2, 23), heated in a heat exchanger (3, 17) to approx. 750°C and passed to a suspension reactor (4) in which the temperature by burning the carbon contained in the flyash and supplemented, if necessary, with fuel added to the reactor separately (5) is raised to 800 to 900°C, there being also added simultaneously to the flue gas ammonia at (6, 6a) either to the reactor (4) or immediately after same in duct (16), whereby the heat treatment in the reactor causes the SO x  content of the flue gas to become bonded as CaSO₄, while its NO x  content reacts with the NH₃ to form free nitrogen and water vapour. Heating of the boiler flue gas in the heat exchanger (3, 17) is either effected by passing the approx. 900°C hot exhaust gas from the separator cyclone (7) of the suspension reactor (4) directly to the heat exchanger or by a part of the ashes (12) separated in the flue gas filter (11) being passed to a heat exchanger (18) coupled after the reactor (4), heated by using the exhaust gas of the separator cyclone (7) to approx. 850°C and by-passing the reactor being passed as heat-transfer medium to the heat exchanger (17) upstream of the reactor, whereupon the partly cooled ashes are recycled by conveyor means (21, 22) to the heat exchanger (18) for renewed heating, and where during the recycling step ground limestone (23) is added for the SO x  cleaning process in the reactor (4).

Abstract: This disclosure relates to a method for measuring the concentrations of sugars in liquids by the use of near infrared as well as an apparatus for practicing said method. 
     The method comprises a step wherein the absorption spectrum of the sugar under investigation existing at a first depth relatively close to the surface in a sample (15) is computed by using relatively weak power of near infrared, a step wherein the absorption spectrum of the sugar under investigation existing at a relatively deep second depth in the sample (15) is computed by using relatively strong power of infrared, and a step wherein the concentration of the sugar under investigation in the sample (15) is determined by computing the absorption spectrum of the sugar at a different depth between said first and second depths on the basis of the results of measurement in said first and second steps. The wavelengths for the use for said absorption spectrum are selected from anyone of wavelength bands of 950-1,150 nm, 1,150-1,300 nm, and 1,300-1,450 nm. 
     Since, according to this method, wavelengths which are shorter and closer to the visible region than in the prior art are used, the method enables the measuring light beams to penetrate deeper in a living tissue and makes it possible to measure the concentrations of sugars existing in a deeper region non-invasively.
