Patent EP-0044957-A2 (EP)
Inventor: MISCHIATTI MARIO
IPC: F27D17/00

Abstract: In melting installations, including cupolas for cast iron production, the effluent gases contain latent and sensible heat. The purpose of the system is to recover such heat in order to produce, when so required, electric and/or heat energy, under the form of steam and/or hot water. As melting installations such as cupolas can have intermittent operation characterized by halts, also daily halts, and as their effluent gases contain dust and in some cases steam and/or drops of water, therefore possessing potentially fouling and corrosive properties, it follows that the latent and sensible heat recovery from the above mentioned gases involves certain difficulties. 
     For this purpose - that is to say, for the elimination of such difficulties - the Applicants have proposed a system consisting of a thermal unit for heat recovery with consequent production of steam and/or hot water and a converter unit which transforms the heat energy into electric energy, when so requested. 
     The characteristic part of the system actually consists of just its thermal unit only which advisably consists of two interconnected boilers, of which the first one is of the water tube type functioning by radiation and convection, with two round manifolds, and the second one is of the fire tube type with smooth or finned internal surfaces. 
     The superheater is made up of two sections, the first one of which is installed inside the top part of the first boiler, while the second section is installed between the two boilers. The steam separator is common to both boilers and is installed above them. 
     An economizer and combustion air preheater are installed downstream to the second boiler. The fumes are then sent to the chimney. When electric energy is to be produced, the steam from the superheater is sent to a turbine and is returned to the thermal unit as feed water in the economizer.

Abstract: © Preferably, the pressurized reactor coolant is utilized to raise the drive rod into contact with and to pivot the latching mechanism so as to allow the drive rod to pass the latching mechanism. The pressure in the housing may then be equalized which allows the drive rod to move downwardly into contact with the latching mechanism but to hold the shaft in a raised position with respect to the reactor core. Once again, the reactor coolant pressure may be utilized to raise the drive rod and thus pivot the latching mechanism so that the drive rod passes above the latching mechanism. Again, the mechanism pressure can be equalized which allows the drive rod to fall and pass by the latching mechanism so that the drive rod approaches the reactor core.

Abstract: A pipelined charge coupled analog to digital converter which provides a plurality of serially arranged pipelined stages that are connected to pass signal and reference charge packets from stage to stage in a serial progression. The converter includes one stage for each bit desired in the output bit stream so that a converter having n stages provides an n bit digital word corresponding to the input analog signal charge. While the time necessary to perform the analog to digital conversion is the sum of operating times of all the stages, because the converter is pipelined, each successive n bit digital word representing a different successive charge packet is produced succeeding a preceding digital word representing a preceding signal charge packet, by a delay equal to the processing time of only a single stage.The Figure shows a three stage converter. In the initial stage, the reference charge packet (Q<sub>r</sub>) from generator (CG) is halved by splitter (51) and the halved charged held by (FET FG1). The input charge is held on (FET FG2) and the two charges compared at (C1). The result of the comparison is delayed via delay stages (DR) and also used to control switches (SW1, SW2). In the intermediate or typical stage, the comparator (C<sub>2</sub>) similarly compares charges held on (FET FG3 and FG4). the magnitude of the charges to be compared is determined by the setting of the switches (SW1, SW2). The final stage similar to a typical stage but includes charge drums D.The stages implements the algorithmwhere b<sub>n</sub>, is 0 or 1 depending on the comparison ( ) and b<sub>x</sub> is the inverse of bx.

Abstract: An angular rate sensor of the class wherein two electro-magnetic waves are travelling in opposite directions is disclosed. In this sensor (100) each wave is substantially travelling about a closed-loop path. The frequency of each of said waves is a function of the rate of rotation of said closed-loop path so that a corresponding phase relationship is established between said waves as a function of the rate of rotation. To prevent a lock-in esror biasing means (30) are provided for dithering the angular rate sensor (100). Control means (32) are controlling said biasing means (30) in orderto alter the phase ψ of said phase relationship such that phase values occurring at a pair of successive occurrences of dψ/dt being zero and d 2 ψ/dt 2  being of the same polarity are such that said phase values differ by π radians (Fig. 3).

Abstract: Upstream of the cross-flow heat exchanger (2) the used kilning air of kilns with one floor (1) is divided into two subflows, of which one is used to heat the kilning feed air in the cross-flow heat exchanger (2) and the other is used as a heat source for a heat pump and fed through the evaporator (3) of the latter. After the latter subflow has been cooled in the heat pump evaporator (3) and demoisturised, it can be mixed with fresh air - allowing for the weather conditions - and the total airflow formed in this process can be fed to the cross-flow heat exchanger of the kiln as feed air. After a further modification, the used airstream from the evaporator (3) of the heat pump can be used for cooling the germinating box and fed to the germinating box (10). If necessary, fresh air can be fed into this subflow upstream of the heat pump evaporator (3) or the last auxiliary heat pump evaporator (3''). <IMAGE>

Abstract: A DC amplifier uses complementary npn and pnp output transistors on n-type and p-type substrates, respectively. The output transistors are in an emitter-follower configuration with no emitter resistor to prevent thermal runaway. Instead, emitter-follower driver-stage transistors are provided on the same substrates as the output transistors to force a reduction in the bias voltage on the output stage when the temperature of an output transistor increases. This circuit prevents thermal runaway and temperature-dependent offsets without emitter resistors, which would increase output impedance, and without feedback from the output stage to the input stage, which would slow the response of the amplifier. Additionally, compensation-network transistors are provided to eliminate offsets resulting from driver-and output-transistor base-to-emitter voltage differences caused not only b y temperature differences between the transistors on different substrates but also by manufacturing variations. The compensation-network transistors, like the driver-stage transistors, are on the same substrates as the output transistors. They are connected to provide a compensation voltage that is equal to the difference between the base-to-emitter voltages of transistors on the two substrates. The compensation voltage is used to cancel offsets that would otherwise result from such differences.
