A headgear for use with a mask includes a first strap being configured to engage a back of a patient's head and extend on either side of the patient's parietal bone behind the patient's ears and assume, in use, a substantially circular or oval shape. At least a portion of the first strap is substantially inextensible. The headgear also includes at least one second strap configured to removably connect the first strap to the mask. The second strap may be more extensible than the first strap. At least a portion of the first strap is self-supporting such that the headgear maintains a three dimensional shape when not in use. The substantially inextensible portion of the first strap is constructed to resiliently return to a predetermined shape when not in use. The arcuate region includes a first portion that may be arranged to align substantially parallel with a top of the patient's head and a second portion being arranged to align substantially to a rear surface of the patient's head.

A versatile compartmentalized cell culture device, with a selectively permeable membrane separating the compartments, provides many attributes relative to traditional devices. It can be configured for high-density cell culture, co-culture, and sample dialysis while rolling or standing still. It can also be configured for continuous movement of liquid between compartments. The wide combination of attributes not found in other membrane based cell culture and bioprocessing devices includes more cell capacity, more cell secreted product capacity, higher cell and product density, increased medium capacity, minimized use of exogenous growth factors, compatibility with standard cell culture equipment and protocols, increased scale up efficiency, capacity to function when rolling or standing still, capacity for perfusion without the need for pumps, and more efficient sample dialysis.

A method and system are described for the on-board treatment of a hydrocarbon-fueled internal combustion engine (ICE) exhaust gas stream to reduce CO2 emissions from the vehicle which include:a. contacting the exhaust gas stream with a CO2 sorbent capture agent on board the vehicle to produce a mixture containing modified CO2-containing sorbent and a treated exhaust gas stream with reduced CO2 content;b. separating the modified CO2-containing sorbent from the treated exhaust gas stream;c. passing the modified sorbent in heat exchange with heat from the ICE to release CO2 and regenerate the CO2 sorbent capture agent;d. recycling the regenerated CO2 sorbent for use in step (a);e. discharging the treated exhaust gas stream having a reduced CO2 content into the atmosphere;f. recovering and compressing the CO2 for temporary storage on board the vehicle.

A process for assembling a rigid-flex printed circuit board (PCB) is presented. During operation, the process receives rigid-flex PCBs that are to be coupled together, wherein a rigid-flex PCB includes flexible PCBs coupled to rigid PCBs. The process then places the PCBs onto a carrier which is configured to: align the PCBs so that bond regions located on the flexible PCBs overlap with bond regions located on corresponding flexible PCBs, and apply pressure to the overlapped bond regions. The process then sends the carrier through a reflow oven which reflows solder on the PCBs so that the components become mechanically and electrically coupled to the PCBs. The temperature profile generated by the reflow oven and the pressure applied by the carrier cures and sets an anisotropic conductive film located in the bond regions so that the overlapped flexible PCBs become mechanically and electrically coupled together.

A process for operating a water recovery plant comprising charging a storage tank with water contaminated with solids water recovered from a manufacturing or construction process, determining a parameter associated with the concentration of one or more selected contaminants in the storage tank, diluting the water contaminated with solids whereby the concentration of the one or more selected contaminants in the storage tank is at or below a desired level, and utilizing water from the storage tank in the manufacturing process.

A medical bag of multi-liquid missing type for one-shot operation for opening the weak seal portion, which makes it possible to obtain simultaneous opening of a blending medicine inlet.The medical bag 10 is formed of a soft film material and having a weak seal portion, which divides the space inside the bag into a plurality of compartments 20 and 22. A blending medicine inlet port 14 is arranged adjacent the one compartment 20. The inlet port 14 includes sealed compartments 36A, 36B and 36C for storage of the respective blending medicines. The inlet port 14 is usually closed by a peel film member 44 for preventing the blending medicines from being discharged. The peel film member 44 is strongly adhered to the opposed surface of the plastic film constructing the medical bag. An integral movement of the peelable member with respect to a widening displacement of the medial bag is obtained when the weak seal 18 is opened under a pressing force, so that the peelable member 44 is separated from the inlet port 14, resulting in a discharge of the blending medicines from the compartments 36A, 36B and 36C into the medical bag.

A process for the preparation of a polyether polyol containing at most about 15 ppm of sodium and potassium, comprising: (a) reacting an initiator having at least two active hydrogen atoms with at least one alkylene oxide in the presence of a catalyst having an alkali metal hydroxide to form a polyether polyol reaction product; (b) neutralizing the polyether polyol reaction product obtained in step (a) by contacting this reaction product with phosphoric acid and water; and (c) removing the salt crystals from the polyether polyol and recovering the neutralized polyether polyol containing at most about 15 ppm of sodium and potassium, wherein no adsorption agent and no hydrate of a metal salt of the acid are used before, during or after the neutralization.

The present invention relates to a fibre sheet material and method of laying up fibre sheet material to manufacture wind turbine blades. The invention further comprises a blade manufactured by the method as well a use of such a blade. One aspect relates to an oblong fibre sheet material (26) for wind turbine blades, where a surface layer (14) is having a width, which in the lateral direction is broader than a lateral, unidirectional layer (10), and lengthwise side faces of at least the surface layer is provided with a thinning of a thickness of the layer to obtain favourable joints. Another aspect concerns manufacturing a wind turbine blade shell comprising laying fibre sheet (26) materials in a blade mould (20), where the sheet materials lengthwise are positioned in a direction corresponding to a chordwise direction of a turbine blade direction of the mould and overlapping in a spanwise direction. The effect obtained is a significant reduction in the amount of waste material compared to laying fibre sheets in the spanwise direction.

The present invention relates generally to the field of waste processing. The method comprises separating waste into at least two parts, comprising: (i) mainly food waste (fines) and (ii) mainly paper and other recyclable material (overs). The overs are pulped and washed to obtain a cellulose-rich biomass and the fines are optionally processed separately to recover a cellulose-rich biomass and the cellulose-rich biomass from both the fines and the overs may be combined.

The present invention relates to a method for removing at least one contaminant from a gaseous stream substantially comprising carbon dioxide. More specifically said method includes the step of subjecting the gaseous stream to an absorption step in which the absorbent is liquid carbon dioxide.
