Abstract: Combustion Control System Abstract In  a  combustion system,  the  economic  optimum efficiency is achieved by periodically computing a relative  index of  combustion efficiency using  the combustion chamber as a real-time,  on-line calori-meter.  This is accomplished by first determining the combustion chamber  inputs  and outputs  required  to calculate a relative index of performance (including measuring the amount of heat released or work per-formed at the present air/fuel ratio including the stack losses, without oxygen and/or carbon monoxide sensors), sequentially comparing the latest relative index value with the previous value, then adjusting the  air/fuel  ratio  to  achieve  an  improved  index value.

Granted: 1990-07-17
Abstract: ABSTRACT OF THE INVENTION     A failure compensation circuit automatically reduces the output voltage of a power supply when a portion of a load drops out.  The compensation circuit includes a circuit for generating a control signal representative of the desired voltage across the load.  A power supply supplies voltage to the load in response to the control signal.  An input signal representative of the current delivered to the load is produced which decreases whenever a portion of the load drops out.  The circuit for generating the control signal is responsive to the inout signal for adjusting the control signal such that when the current delivered to the load decreases, the voltage delivered to the load is automatically reduced.

Abstract: A device for producing alternating electric current of high frequency for power consumers such as fluorescent tubes (Ly1, Ly2) comprises a transformer with a winding (n3) connected in series with an output terminal (e) and active electronic components such as transistors (T1, T2) controlling the output current, the transistors being controlled by electric voltages produced by inductive feedback in feedback windings (n11, n12). Magnetic saturation is utilized to modify the inductive relationship in such a way that the transistors (T1, T2) cyclically change the direction of the output current. The feedback takes place in two magnetic cores (Tr1, Tr2) of the transformer, each core being provided with at least one further electric magnetization winding designated a command winding (n5, n6) as electric current is fed through the command windings to control magnetic saturation of the magnetic cores (Tr1, Tr2). As a result, combined control of the frequency and of the active electric power in the fluorescent tubes (Ly1, Ly2) is possible so that the luminous power may be controlled over a wide range while suitably high voltages can be maintained to ignite the tubes properly.

Abstract: The present invention concerns a procedure for bleaching cellulose pulp obtained from hardwood, wherein bleaching chemical containing chlorine is used. The essential feature of the invention is that the residual chlorine content of the bleached pulp is reduced by subjecting the pulp to enzyme treatment. With the enzyme especially the removal from the pulp of chlorine-binding extractive substances present in hardwood pulp is promoted. The invention furthermore concerns the use of enzyme towards lowering the residual chlorine content of bleached cellulose pulp made from hardwood. Such cellulose pulp is particularly contemplated which will be converted into foodstuff package cardboard or paper, which are commonly disposed of by burning. Lowered chlorine content reduces the risk of producing toxic dioxin at the incineration step.
