Title: Method for producing sterile air for medical use and apparatus for carrying out the same
Inventor: DELACHAPELLE HENRI
IPC: A61L9/16

Granted: 1989-05-16
Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a method and apparatus for producing sterile air suitable for being administered to intensive-care patients in hospitals.  The main purpose is to obtain such sterile air starting from atmospheric air, with a more complete degree of purity than available from conventional methods using atmospheric air, and to obtain this medical-grade air free of gaseous contaminants and germs, at a cost substantially lower than when such air is prepared by mixing pure nitrogen with pure oxygen. The invention comprises compressing atmospheric air through at least one dry-piston compressor, condensing water vapor out of the compressed air through expansion into a buffer tank, fil-tering out dust particles down to micron size in a prefilter, drying the air through an adsorption desiccator and elimi-nating gaseous contaminants through an adsorption-desorption device.  A second dust filter is provided for trapping any dust released from the adsorption units.  The air is then treated for the elimination of biological contaminants, such as viruses and bacteria, by flowing through a sequence of three biological filters of the coalescence type, and finally through a cold sterilizing unit.  A feature of the invention is that the desiccator and the unit for the elimination of gaseous contaminants use an active product of the same nature, namely a combination of metal oxides with K, Na and Mg sili-cates, the amount of this product being larger in the second unit than in the desiccator.

Abstract: ABSTRACT        Improvements in or relating to teartapes A teartape for packaging materials, and particularly such materials based on polyolefine films, comprises a base film coated with a pressure sensitive adhesive composition.  The teartape is affixed to the packaging material by the adhesive composition.  This avoids the problem of distortion which can occur when affixing conventional teartapes to such packaging materials by means of hot melt wax compositions.  The teartape is applied to moving packaging material by controlling the speed of the teartape in accordance with the speed of the packaging material so as to reduce tension imbalance.  The speed of the teartape may be controlled in dependence upon the tension in the teartape.  This can be achieved by supplying the teartape from a dispenser having a brake means (4,5) and a drive means (10,11,12) for regulating the speed of the teartape in dependence on the tension in the teartape.

Abstract: COOLANT/REFRIGERANT TEMPERATURE       CONTROL SYSTEM          ABSTRACT:     A variable speed  fan drive  (46),  operated  in response to the sensed coolant temperature in an inter-nal combustion engine for a vehicle, blows a controlled amount of air through the engine's radiator (48) to maintain the coolant temperature in a desired narrow operating range.  The air pulled in by the fan also cools the refrigerant flowing through the condenser (49) of the vehicle's air conditioning system, the condenser (49) being positioned in front of the coolant radiator (48).  If insufficient condenser cooling occurs, even though the coolant may be adequately cooled, the refri-gerant temperature rises and causes the compressor discharge pressure  in the air conditioning  system to increase.  That pressure is monitored or sensed (52) and if it exceeds a predetermined maximum allowable level the normal operation of the control system is overridden and the fan (46) is driven at its maximum speed to maximize the air blown through the condenser (49) and radiator,  (48)  thereby  decreasing  the  refrigerant temperature and thus the discharge pressure.

Abstract: FLOATING TARE ADJUSTMENT FOR CONTINUOUS CONVEYOR WEIGHING SYSTEMS               Abstract of the Disclosure A conveyor  (10)  conveys  stacks of newspapers  to a weigh station (A).  The weigh station produces a digital weight signal which is processed by an electric circuit (B)   to  determine  whether  each  bundle  contains preselected  number  of  newspapers.    A  display   (F) provides an indication whether or not the weighed bundle contains  the  preselected  number  of  newspapers.   More specifically,   the   electronic   circuit   includes   a microprocessor  (22)  which  is  programmed  to  store  a preselected  number  of  acceptable  bundle weights  in  a tare calculation memory (72).  An algorithm implementing routine (78) averages the stored weights to determine an average  weight  or  tare.   A  subtraction  circuit  or routine  (52) subtractively  combines  the  tare  and  the measured  weight.   A divider  circuit  or  routine  (56') divides the tare by twice the number of newspapers which are to be in each bundle to determine the weight of half a paper.   A comparing circuit or routine (54) compares the weight difference signal with the weight of half an article to determine whether or not each measured bundle contains  the  proper number  of  papers.   If  the bundle contains  the  proper  number  of  papers,  the  measured bundle weight replaces the least recently stored weight in  the  tare  calculation  memory  and  a  new  tare  is determined.   In  this  manner,  the  tare  is  readjusted after every acceptable bundle is weighed such that the tare  is a  function  only of  the weight of  precedingly accepted  bundles   and   may   fluctuate   widely   with variations in the density of ink, paper, and the like.

Abstract: ABSTRACT        The monitoring device simultaneously senses the voltage at the interconnection points between a plurality of series connected current interrupting devices.  When current is interrupted by any one of the devices, the conductivity statuses of all devices are latched and stored until reset in a storage device which provides a signal indicating which of the devices caused current flow to be interrupted.   The monitoring device  thus detects both intermittent and sustained faults.   The monitoring device employs optically isolated digital electronic circuitry for direct interconnection with AC control circuits.
