Patent EP-0039956-A3 (EP)
IPC: G01N27/18
Filed: 1981-05-13
Abstract: Die Meßeinrichtung zur Gasanalyse nach dem Wärme­
leitfähigkeitsverfahren weist eine mit einem Gaseinlaß und 
einem Gasauslaß versehene, von einem Meßgas durch­
strömte Meßkammer auf, in der ein mit Konstantstrom 
beheizter elektrischer Leiter in Form eines Platindrahts aufge­
spannt ist, dessen Temperatur und damit sein Widerstand 
von der Wärmeleitfähigkeit des ihn umgebenden Meßgases 
abhängt.  
     Die Meßgasströmung durch die Meßkammer wird 
zyklisch unterbrochen, die Messung des Widerstandes des 
Heizleiters erfolgt erst dann, wenn das nach Unterbrechung 
der Gaszufuhr in der Meßkammer verbliebene Gasvolumen 
strömungsfrei ist und die strömungsbedingte Temperaturän­
derung des Heizleiters abgeklungen ist. Die so gewonnene 
Folge von Meßsignalen wird in einer im Takt der Meßgasbe­
strömung gesteuerten Halteschaltung verarbeitet, deren 
stetiges Ausgangssignal sich mit der Höhe der Meß­
signale ändert.  
     Die Einrichtung wird bei kontinuierlichen gasanalyti­
schen Messungen eingesetzt, bei denen ein Wechsel in der 
Zusammensetzung des Meßgases schnell erkannt werden 
muß, die also eine hohe Ansprechgeschwindigkeit verlangen.

Abstract: The control mechanism is for pneumatic apparatus of the 
kind comprising a piston-and-cylinder motor 15 coupled bet­
ween two relatively-movable parts, such as the door-leaves 
11 and 13, for driving them, when energised, to a predeter­
mined relative position. A pilot valve 26 is actuated when 
required to switch the apparatus to an emergency mode by 
isolating the motor from its power source and discharging it 
into an emergency reservoir 29 having a volume large com­
pared with the maximum volume of gas in the motor. While 
the pilot valve is actuated, the relatively-movable parts are 
urged towards their predetermined relative positions by a 
force small compared with the normal operating force. The 
pilot valve 26 may be arranged to operate operation of an 
emergency release bolt 32, on obstruction detected by a 
detector valve 20 (in which case a timing reservoir 23 provides 
time delay before full power is restored), on power failure, or 
as required.

Abstract: A monitoring system for determining the concentration 
of oxygen in the product gas of an oxygen enriching system 
includes differential pressure regulator (12) means for reduc­
ing the pressure of the product gas, for regulating the 
pressure of the product gas at a preset level, and for 
referencing the regulated pressure to atmospheric pressure. 
Solenoid valves (14, 22) allowing product gas to pressurize 
the monitoring system in a first condition and to allow 
product gas to vent the monitoring system to the atmos­
phere in a second condition are also included. Restrictive 
orifices (16, 20) upstream and downstream of a bed of 
molecular sieve material eliminate pressure spikes in the 
monitoring system. A bed of molecular sieve material (18) 
adsorbs oxygen from the product gas wherein, in a first 
condition, with the system pressurized, the upper pressure 
limit is attenuated as the molecular sieve bed adsorbs 
oxgyen from the product gas, and, in a second condition, 
with the system vented to the atmosphere, the lower 
pressure limit is attenuated by the rate of desorption of the 
oxygen from the molecular sieve bed. A pressure transducer 
(26) means for converting the system presure to an electrical 
analog of that pressure and compares the electrical analog to 
a reference so that oxygen concentration can be inferred.

Abstract: An extracorporeal blood circulation system including a 
line for withdrawing the venous blood from the patient, an 
artificial lung provided on the line, a reservoir for the blood 
withdrawn, a blood supply line for sending out the blood 
from the reservoir to the artery of the patient, and a blood 
supply pump provided on the blood supply line and serving 
as an artificial heart. The amount of blood to be supplied is 
automatically controlled to maintain the arterial pressure of 
the patient in a suitable required range. The blood supply 
pump is stopped when the arterial pressure of the patient 
measured is above a predetermined upper limit value, while 
the pump is driven when the arterial pressure has lowered 
to a level below a lower limit value. The amount of blood to 
be withdrawn is also controlled automatically to keep the 
central venous pressure of the patient approximately con­
stant. The blood withdrawing line has a blood withdrawing 
pump. The reservoir is connected to the inlet side of this 
pump by a shunt line having a valve which is usually 
opened. The valve is closed when the central venous pres­
sure exceeds a predetermined upper limit level. A vertical 
overflow tube detects the central venous pressure exceed­
ing the upper limit level.

Abstract: A vertical type screening machine for granular material 
comprises a housing. A rotary drum assembly is rotatably 
mounted within the housing and comprises a drum having a 
substantially vertical rotary axis and a helical blade helically 
wound around a circumferential surface of the drum. A 
cylindrical screen member disposed between the drum 
assembly and the housing cooperates with a peripheral wall 
of the housing to define therebetween a first chamber and 
cooperates with the circumferential surface of the drum to 
define therebetween a second chamber. The granular mate­
rial to be screened is introduced into the top of the second 
chamber. Upon the rotation of the drum assembly, the 
granular material introduced into the top of the second 
chamber is moved toward the bottom of the second chamber 
by the helical blade and due to gravity. During the movement 
of the granular material toward the bottom of the second 
chamber upon the rotation of the rotary drum assembly, the 
granular material is subjected to a centrifugal force by the 
helical blade so as to be moved radially outwardly toward 
the screen member so that granular material having a 
relatively small size contained in the introduced granular 
material is introduced into the first chamber through the 
screen member. The remaining granular material within the 
second chamber is discharged from the bottom of the 
second chamber.

Patent EP-0172623-A3 (EP)
Title: Optical measuring device using a spectral modulation sensor having an optically resonant structure
IPC: G01J3/26
Filed: 1985-06-25
Abstract: Physical changes induced in the spectral modulation sensor's optically resonant structure by the physical parameter being measured cause microshifts of its reflectivity and transmission curves, and of the selected operating segment(s) thereof being used, as a function of the physical parameter being measured. The operating segments have a maximum length and a maximum microshift of less than about one resonance cycle in length for unambiguous output from the sensor. The input measuring light wavelength(s) are selected to fall within the operating segment(s) over the range of values of interest for the physical parameter being measured. The output light from the sensor's optically resonant structure is spectrally modulated by the optically resonant structure as a function of the physical parameter being measured. The spectrally modulated output light is then converted into analog electrical measuring output signals by detection means. In one form, a single optical fiber carries both input light to and output light from the optically resonant structure. When more than one input measuring light wavelength is used, means may also be provided to divide the input light wavelengths into two portions and then take the ratio thereof. This provides several advantages simultaneously, such as enabling longer operating segments and microshifts to be used for greater sensitivity or detection range, and also eliminates certain errors caused by fluctuations in input light intensity or by changes in light intensity caused by optical fiber bending and optical fiber connectors.
