Abstract: Disclosed are DNA sequences which code for antigenic proteins, methods for indentifying such DNA sequences, and antigens coded for by such DNA sequences. 
     The first step of the method is to provide a multiplicity of DNA sequences. These sequences are then inserted into DNA expression vectors to form recombinant expression vectors. The expression vectors are inserted into suitable hosts to form transformants which express the DNA sequences. The transformants are then contacted to antibodies directed against  Eimeria  antigens to identify transformants containing DNA sequences which code for  Eimeria  antigens. These antigens are then produced from the DNA sequences identified as coding for the antigens. The antigens so produced are contacted to white blood cells which effect a cell-mediated immune response, which white blood cells are sensitized to an antigenic  Eimeria  protein, to thereby identify DNA sequences which code for antigens that induce a cell-­mediated immune response to avian coccidiosis.   
     The DNA sequences of the present invention comprise cloned genes or fragments thereof that code on expression for antigenic protein that activates white blood cells which effect a cell-mediated immune response, which white blood cells are sensitized to an antigenic  Eimeria  protein.

Abstract: An output buffer circuit includes a prestage circuit (1) which generates a first potential and a second potential (an intermediate voltage) based on the voltage of an input signal (Vin). The first potential is higher than the second potential. A final-stage circuit (2) generates an output signal (Vout) by controlling a current passing therethrough from a power source (V DD ) on the basis of the potential of the input terminal. The output signal is supplied to an ECL circuit through the output terminal. A control circuit (4) generates a control signal during a predetermined time when a change in voltage of the input signal occurs. A bypass circuit (3) sets the potential of the input terminal of the final-stage circuit lower than the second potential and discharging a parasitic capacitance coupled to the input terminal during the predetermined time defined by the control signal supplied from the control circuit when the prestage circuit outputs the second potential in response to a change in voltage of the input signal.

Abstract: AC line monitoring is provided for uninterruptible power supplies to detect AC power system line faults by comparing the presently received cycle of the AC power line signal with a reference waveform. The reference waveform is formed of a composite of waveforms from prior cycles which adapts over time to the shape of the AC power line waveform, so that waveforms other than pure sinusoids can be accepted without triggering false fault conditions. The composite reference waveform may be formed of essentially all samples from prior cycles with exponentially decaying weighting. An excessive deviation of the current waveform from the reference waveform results in a fault being detected which causes switching of the uninterrupible power supply to provide backup power. The RMS value of the power line voltage is also estimated on a substantially real time basis, preferably by calculating the RMS value of the reference waveform, to provide a fault condition signal when the estimated RMS value falls below a selected level, which also can be utilized to cause switching of the uninterruptible power supply.

Abstract: In a method for starting up automatically a continuous casting installation, molten metal (11) is poured out of a vessel (10) in a controlled manner by means of a plug (15) provided in the said vessel and a continuous casting mould (20) closed off at the bottom by a dummy bar head is filled with the molten metal (11). During filling, the plug (15) is opened and closed several times at programme-controlled time intervals and with different opening and closing travels (s1 to sn) assigned to these time intervals. During the first or the first few opening(s) (s2), the plug (15) is preferably moved approximately into the fully open position (P1) and its opening travels (s3,s4,s5) are consequently reduced as the filling level (h) increases. With this very precise automatic start-up method, starting up can be performed with an extremely high degree of reliability and operational safety.

Abstract: The inventive method of producing a device having non-alloyed ohmic contacts (88,89) of common composition to both an n-doped (81) and a p-doped (86) region of a semiconductor body comprises deposition of a Ti/Pt layer on the p-doped as well as the n-doped region, followed by rapid thermal processing (RTP). Exemplarily, the device is a semiconductor layer, the n-doped region (81) is InP, the p-doped region (86) is InGaAs or InGaAsP, and RTP involves heating in the range 425-475°C for 10-100 seconds. The method comprises fewer processing steps than typical prior art methods, reduces the danger of fabrication error and of wafer breakage and, significantly, results in contact that can be relatively thermally stable and can have very low specific contact resistance (exemplarily as low as 10⁻⁷ Ω·cm²).

Abstract: A helicopter engine speed reference (66) is increased (113, 103-105) in response to heavy rotor loading (108). The reference speed is faded up (113, 104) at a rather rapid rate to 107% of rated speed (114). After a fixed time interval (118), reduced rotor loading (119) will cause the reference speed to be faded down slowly (120, 103-105) to rated speed (121). If torque exceeds 111% of rated torque (117), the reference speed is similarly faded down (120, 103-105).
