Title: A method of reducing sulphur-oxide and nitrogen-oxide emission when burning solid fuel on travelling grates
IPC: C10L10/00
Filed: 1985-03-28
Abstract: The invention relates to a method of reducing sulphur-oxide and nitrogen-oxide emissions when burning solid fuel admixed with lime powder in a boiler (1) provided with mobile grate, preferably a travelling grate (2). This is effected in a first step, in which sulphur dioxide remaining in the flue gas is bound by injecting (at 28) a horizontal curtain of dolomite powder or the like into the hearth above the bed (2) in a hearth zone where the temperature at maximum is about 1050-1110 DEG C or somewhat lower. In a second step flue gas is recycled to the combustion-air inlet (7, 25) beneath the grate in an amount such that the surface temperature of the bed will not substantially exceed 1100 DEG C, resulting in the binding of sulphur by the formation of calcium sulphate, and low nitrogen oxide emission.

Patent EP-0226436-A3 (EP)
IPC: H04W88/02
Filed: 1986-12-09
Abstract: In a radio paging receiver which is capable of 
responding to a message signal specific to the receiver 
and which comprises a display unit (90) and a message 
processing section (60) for making the display unit 
display the message signal, the message processing 
section monitors the message signal to produce a drive 
signal after reception of the message signal until the 
message signal is delivered to the display unit. 
Responsive to the drive signal, a combination of 
transistors (3 and 2) keeps power supply of a power 
source l8 to the message processing section as long as 
the drive signal is produced. Such power supply is 
carried out regardless of a state of a power supply 
switch (20). A decoder (40) makes a speaker (80) 
generate an alarm in response to the drive signal after 
the power supply switch is put into an off state. The 
alarm lasts until the switch is put into an on state. 
The message processing section may comprise an RAM for 
storing the message signal as a stored signal and 
another RAM for storing specific information indicating 
whether or not the stored signal is delivered to the 
display unit. Alternatively, such specific information 
may be stored in a memory included in the decoder.

IPC: B06B1/02
Filed: 1987-12-31
Abstract: An ultrasonic frequency generator sets a plurality of 
parameters for a transducer to enable an ultrasonic operation to 
meet a plurality of criteria. The generator produces sets of 
power trains, each formed of a sequence of power bursts of an 
ultrasound signal having a variable amplitude and a variable 
frequency. The power bursts are provided with controllable 
durations and are separated from one another by controllable 
quiet times. A cavitation density function generator controls 
the amplitude of the power bursts. The power trains are provided 
with controlled durations, and variable degas time durations are 
included between sequences of bursts of the ultrasonic signals. 
A further function generator is used to control the frequency of 
the signal, thus providing a swept frequency burst. A controller 
is provided for setting the center frequency of the swept signal. 
The generator thus provides a waveform with seven controllable 
parameters which may be set to conform to any operational 
criteria.
