circuit includes: an identifying circuit which automatically 
identifies the type of probe to which the first circuit is cou­
pled; short circuit detection; a digitizing circuit for digitizing 
the electrical signal from the first circuit; and a processing 
means including a look up table for each probe type for de­
termining the temperature reading in degrees from the digi­
tized signal and the output of the identifying circuit. The first 
circuit includes a linearization circuit for partially linear­
izing the proportionality of the electrical signal with patient 
temperature. A plurality of temperature channels may be 
provided with the inclusion of an electrical switching circuit 
for sequentially coupling each of the probes to the digitizing

Title: Process and apparatus for purifying gases, particularly for desulfurizing and denitrating smoke
IPC: B01D53/34
Filed: 1987-01-14
Abstract: Flue gases from firing installations are purified by multi-stage adsorption and catalytic reaction in migrating beds, bearing a crossflow and moving by gravity, of carbonaceous granular materials, at least two migrating beds being arranged in series with respect to the gas path in such a way that the denitrification is carried out in the second migrating bed or in one of the subsequent ones. When high gas rates from industrial firing installations are purified, the formation of streaks leads to wide fluctuations with respect to the sulphur dioxide concentrations. 
<??>This disadvantage is eliminated by subjecting the prepurified flue gas (9) which emerges from a first migrating bed (7) and has a locally variable sulphur dioxide concentration gradient, to repeated thorough mixing before the addition of ammonia as a reagent for the denitrification.

Patent EP-0289854-A3 (EP)
Title: Fluid dispenser
IPC: B05B11/00
Filed: 1988-04-20
Abstract: In a dispenser (1) for liquids, a section (39), which can be shortened by compression and thus serves for opening an outlet valve (15), of a piston shaft (11) which is associated with a piston unit (9), is protected against expansion in the original position and over a starting part of the pump stroke by means of a narrow rib routing and released in a part of the stroke subsequent to this starting part in such a way that it can be suddenly compressed by the pressure of the medium acting on the pump piston (10), as a result of which the outlet valve (15) then opens. However, at the start of this compression the section (39) which can be shortened carries out an idle motion after which it entrains the valve closing part (30) of the outlet valve (15) for the purpose of opening. Additionally, the outlet valve (15) can also be mechanically opened by a stop (14) at the end of the pump stroke. As a result, a particularly rapid dispensing of the medium as well as a simple evacuation of the air in the thrust piston pump (2) is made possible. <IMAGE>
Patent EP-0305719-A3 (EP)
Title: Centrifugal brake for control rod drive
IPC: G21C7/12
Filed: 1988-07-20
Abstract: A centrifugal brake is disclosed for a con­
trol rod drive within a boiling water reactor (BWR). 
Control rods within reactors have dual insertion 
mechanisms including a motor drive and a hydraulic 
drive. These drives are concentrically mounted within 
a cylindrical enclosed pressure chamber. The motor 
drive is typically of the ball screw type wherein a 
motor drive rotating threaded shaft through the bottom 
of the cylindrical chamber. The rotating threaded 
shaft drives a ball screw nut within a guide tube which 
urges a hollow piston upwardly. The control rod, 
connected to the upper end of the hollow piston is in 
turn urged upwardly into the reactor. The hydraulic 
drive utilizes hydraulic pressure to move the hollow 
piston and control rod independently from the ball 
screw drive upwardly for insertion into the reactor. 
Where loss of hydraulic system pressure occurs, both 
the weight of the control rod and pressure from the 
reactor can cause reversal of the ball screw drive and 
an undesired retraction of the control rod from the 
reactor. Accordingly, a centrifugal brake is installed 
in between the motor and ball screw threaded shaft con­
centric to a conventional coupling. The brake includes 
at least the one disc rotatably attached to the ball 
screw shaft having at least one and preferably two 
arcuate pawls pivoted on the disc. The pawls are main­
tained in a retracted position with respect to the disc 
by conventional detents. A stationary housing with 
lugs for engagement with the pawls are provided sur­
rounding the disc. When the shaft of the ball screw 
rotates, responsive to pressure induced control rod 
 
 
withdrawal, the brake disc commences to rotate with 
increasing angular acceleration. This angular 
acceleration continues until the centrifugal force 
acting on the pivotal arcuate pawls of the brake 
overcome the force of the detents. When the force of 
the detents is overcome, the pawls pivot outwardly with 
respect to the disc. The pawls engage the stationary 
lug and immediately arrest ball nut shaft rotation and 
therefor control rod withdrawal. Upon motor controlled 
rod insertion, the stationary lugs reset the pawls to 
their respective detents and normal control rod 
insertion can occur. Consequently, unintentional 
control rod withdrawal under reactor pressure is pre­
vented during hydraulic casualties to the control rod 
drive while the capability of motor and the ability to 
reset the brake following inadvertent actuation 
insertion is preserved.

Abstract: A method of manufacturing a semiconductor device 
whereby a wiring material (5) is filled within a recess 
of an insulating film (3), with the upper surface of the 
wiring material (5) being uneven, a coating film (6) 
being evenly deposited on the wiring material (5), the 
wiring material (5) and the coating film (6) being 
etched with tetra-methyl-guanide having the same etching 
speed with respect to the wiring material (5) and the 
coating film (6) in such a manner that the upper surface 
of the wiring material (5) filled within the recess is 
made substantially flat and substantially flush with the 
upper surface of the insulating film (3). A 
tetra-methyl-guanide may be used which has a higher 
etching speed with respect to the wiring material (5) 
than the coating film (6). In this case, the wiring 
material (5) has an indentation above the recess, and 
the coating film (6) is thick above the recess and thin 
above the insulating film (3). Therefore, the wiring 
material (5) within the recess is etched in such a 
manner that the upper surface of the wiring material (5) 
within the recess is made flat and substantially flush 
with the upper surface of the insulating film (3).
