Abstract: A method and apparatus is disclosed for direct reduction of metal oxides, using a rotary kiln, fed with greenball pellets, the kiln having a feed-end and a discharge end. A first chamber within the kiln, and adjacent to the feed-end, is used for drying, preheating and indurating the greenball pellets. Greenball pellets are fed into the first chamber using a conventional mechanism. The feed-end is sealed to prevent egress of process gas from the kiln into the atmosphere and ingress of the atmosphere into the kiln. A first burner is used for drying, preheating and indurating the greenball pellets within the first chamber. A second chamber within the kiln, adjacent to and connected with the first chamber, having a diameter greater than the first chamber, is used for reducing the pellets, the second chamber being adjacent to the discharge end. A second burner may be used for reducing the pellets within the second chamber. Reduced pellets are discharged from the discharge end. The axial angle of the kiln is varied to regulate the flow rate of the greenball pellets from the first chamber to the second chamber.

Abstract: In elevators or lifts, sensing systems are mounted on two doors which move towards and away from sone another to detect obstructions in the opening between them. This ensures the safety of persons using the lifts. The two systems are electrically linked to receive a power supply and to effect data transfer between them. Because the doors are continually in motion the conductors concerned are subject to continual flexure. The more conductors there are, the higher the risk of damage to at least one of them. The present invention relates to a two conductor transmission system for transmitting power and data between two stations. The system comprises first station linked to a second station by only first and second conductors (75A,75B). The first station includes a DC source (72) for supplying the first and second conductors (75A,75B) with DC power, a synchronisation pulse generator (69), a first modulator for modulating the DC power fed to the conductors with the synchronisation pulses, a data terminal connected to said first conductor for receiving data transmitted from the second station, and first inhibiting means (70) responsive to the synchronisation pulses to inhibit the passage of data to the data terminal during the transmission of synchronisation pulses. The second station comprises data signal generating means connected to the first and second conductors (75A,75B) to receive DC power and synchronisation signals therefrom, the data signal generating means being arranged to generate data signals indicative of a monitored condition, a second modulator for modulating the DC power flowing along the first conductor (75A) in response to the   generated data signals, and second inhibiting means responsive to the data signals generated to render the data signal generating means insensitive to the data signals appearing on the first conductor (75A).

Abstract: An integrated circuit includes a monitor device connected between a pin for connection to the more positive lead of the power supply or the less positive lead of the power supply and the more positive voltage supply conductors or the less positive voltage supply conductors on the integrated circuit substrate. The monitor circuit has a threshold circuit (112) such that, insignificant perturbations will not trigger the monitor. The monitor circuit includes a comparator (120) having a reference voltage input (122) such that the same circuit may be used for the more positive side of the power supply, as well as, the less positive side with straightforward modifications. When the monitor circuit detects a significant fault, i.e. one that could falsely switch part of the integrated circuit, it sets a flip-flop (141) to record such an occurrence. The monitor flip-flop (141) cannot be reset by the usual reset signals, in order to prevent it from being cleared by normal diagnostics and error recovery operations.

Abstract: This invention relates to a method of driving a semiconductor device having a bipolar transistor, an insulated gate FET and a thyristor combined together. The method is to first drain that part (I A 1) of an on-current (I A 1, I A 2) flowing in the semiconductor device which flows in a bipolar fashion into a base electrode (30) so as to interrupt the thyristor operation, particularly, in the turn-off operation. After this, a channel (22) is extinguished to interrupt a current (I A 2) flowing in an FET fashion (unipolar fashion) so as to interrupt the FET operation. The above two steps are sequentially effected to turn off the semiconductor device.

Abstract: 2.1 Known protection circuits for laser diodes require a relatively high production cost and are furthermore unsuitable for protecting the laser diodes against electrostatic charges. 
<??>2.2 A protection circuit which can be produced relatively easily and also provides protection against electrostatic charges consists of a radio-frequency limiting circuit (BE) with a radio-frequency attenuating circuit (AT) connected downstream from it. The radio-frequency limiting circuit contains two diodes (D1, D2), which are preferably Schottky diodes, and the radio-frequency attenuating circuit contains one diode (D3), which is preferably a PIN diode. The diodes (D1, D2) are reverse-biased by a DC voltage (UDC) in the case of normal signal levels, and no current flows through the diode (D3). If the signal level exceeds a specific value, the diodes (D1, D2) conduct and limit the signal in a balanced manner. In the case of an electrostatic discharge, there are voltage pulses at the input (I) of the protection circuit (SG), which voltage pulses control the diodes (D1, D2) to conduct and hence provide limiting to a value which is not hazardous for the laser diode (LD). 
<??>3. The drawing shows a circuit diagram of a protection circuit.

Abstract: A self-aligning sampling system is proposed for sampling digital signals, for example in a logic analyser. The sampling system comprises an adjustable delay line with tapping points for clock signals. In conjunction with the system clock, the further clock signals are used to take several samples of the digital signal in a time slot of the system clock. In order to achieve equidistant sampling even in the case of a large process spread in elementary delay units of the delay line, the delay line is calibrated. The system clock is then connected to the data input and expressed in elementary delay units on the basis of measurement. Subsequently, the delay line between clock signal tapping points is adjusted on the basis thereof.

Abstract: In a charged particle beam device, comprising a charged particle source (9) for emitting a charged particle beam, a column comprising particle-optical elements which are enclosed by a column jacket (10) and which serve to accelerate and focus the charged particle beam, the charged particle source comprising an emitter (11) which is accommodated in an emitter chamber (19), a vibration-insensitive suspension of the emitter is achieved by connecting the emitter chamber to the column jacket via a tubular electrode system (25). Because the pumping device (39) cooperating with the emitter chamber is arranged above the emitter chamber and in the prolongation of the column, disturbing effects of the pumping device on the emitter are reduced. Because the power supply unit (47) is arranged in the vicinity of the emitter, high-voltage supply leads can be dispensed with, so that interference signals cannot reach the emitter via the supply leads. The use of optical communication via optical fibres (51) prevents the occurrence of undesirable potentials in the equipment.

Abstract: A dust free, free-flowing, L-LysineHCl granular product is made from a liquid solution or slurry by a spray granulation process. The L-LysineHCl is sprayed onto an agitated bed of L-LysineHCl seed particles until the size of the particles reach a harvest size. In one embodiment, the agitated bed is a fluidized bed. In other embodiments, the agitated bed is a rotating mechanical device including either a drying drum or a disk and cone combination, where the particles are grown in an intermittent spray/dry cycle. Then the harvested particles are sorted for size. Those particles which are a non-acceptable oversize are ground to seed size and returned to the agitated bed. Those particles which are a non-acceptable undersize are remelted, purified, and returned to the liquid solution. Other salts of L-Lysine may also be used, such as an L-Lysine sulfate salt, an L-Lysine phosphate salt, and an L-Lysine calcium salt.
