A plastic resin extrusion line for the production of blown film includes an external thickness control device that provides a controllable amount of air from an inlet side through an annular region to one or two sets of lips. Barriers that can be manually or automatically controlled are provided in the annular region for localized control of air flow and thus for localized thickness control. The pressure drop across the barriers is significant relative to that in the lips.

Automatic thickness profiling for use in blown film and other extrusion lines. The automatic system is integrated into an air cooling ring device either external and/or internal to the bubble or extrusion. The system has or more high resolution circumferentially variable annular air outlets which act to cool the molten resin in a circumferentially variable way. Thin slide plates remain fixed in place except when adjusted to open or close the local annular air outlet by the action of at least one scanning actuator. The actuator is positioned by control signals generated by a control computer which calculates the appropriate local dimension of the variable air outlet in response to circumferential position correlated with thickness variations detected by a film thickness sensor. The film thickness above the frost line is mechanically scanned around the extrusion. In the case of making blown products with internal cooling, counteracting adjustments are made as local flow areas of the internal cooling device are changed to maintain constant the entrapped air volume.

An oscillating hauloff device for removing blown film from an extruding apparatus. The oscillating hauloff includes a stacked ring arrangement which provides a compact and stable structure. The turning bars and idler rolls are encompassed in the ring structure and are arranged to cancel effects of web wandering and wrinkling. A method for making the oscillating hauloff, including CNC machining of annealed ring-shaped weldments, that is economical and simple to manufacture. The turning bars are provided with reinforcements that prevent deflection of the turning bars during use. Further the turning bars are provided with flow restricted outlets and axially extending channels to supply uniform air pressure to float the blown film on the turning bars. A specific arrangement for providing utility services to the oscillating hauloff is also disclosed which employs torsional deflection of the loads during rotation of the rings. The oscillating hauloff is suitable for receiving film extruded downwards with only minor adjustments in structure from the unit for upwardly extruded film.

A gas assisted re-breathing device is disclosed for life support of individuals venturing into harsh environments, particularly the underwater environment, which results in reduced work of breathing. Similar to prior art re-breathers, hoses connect a mouthpiece to direct the flow of breathing gas in a loop like fashion, passing in and out of a flexible gas storage container and a CO2 scrubbing device prior to re-breathing. Disclosed is a pressurized gas assisted re-breathing device, driven by pressurized gas, actuated by the breathing pressure local to the mouthpiece, that acts to move the flexible gas storage container on behalf of the individual and a loop seal valve that is forcibly shut during assisted breathing, which seals the assisted breathing loop to prevent premature venting of breathing gas to the surrounding environment, unless the assisted breathing loop is full, whereupon the loop seal valve opens to allow excess breathing gas to escape into the surrounding environment through forcible exhalation by the individual through one or more conventional one way valves that prevent backflow from the surrounding environment back into the loop. This device significantly reduces work of breathing without unwanted breathing gas loss and further facilitates additional safety features that would otherwise not be practical due to the resultant increase in work of breathing.

An extrusion die with a plurality of die layers stacked one upon the other in a direction generally parallel to the central axis. Each of the layers has an annular flow distribution ring having an outer generally cylindrical surface and an annular feed ring surrounding and engaging the outer surface of the distribution ring. At the engaged surfaces of the feed and distribution ring, the flow from the feed ring is divided into a number of substantially equal flow portions. Seals between adjacent engaged surfaces confine the flow to between the circumferential surfaces of the feed and distribution ring. Half of the flow portions are directed to a recombination region on one side of the distribution ring, and half are directed to a recombination region on the other side of the ring. In recombining, weld lines are formed in high flow areas to minimize the deleterious effect of polymer degredation. Subsequently, the flows on opposite sides of the distribution ring are recombined such that the weld lines from one half are first modified to exhibit lower flow and then are layered with non-weld line portions modified to exhibit higher flow from the other half.

A CO2 measuring device for use in a high humidity environment typically found in re-breathing apparatus, especially underwater re-breathing apparatus, that allows commonly available CO2 gas detectors to function properly and further provides for remote, continuous and/or quantitative sensing of CO2. Under normal conditions found inside re-breathers, a 100% relative humidity condensing environment exists that prevents the use of commercially available CO2 detectors which typically require relative humidity to be less than about 90 to 95% for proper operation. A venturi mixing device is disclosed that is driven by pressurized makeup gases routinely added into the re-breathing loop, acting to draw and mix with a portion of the moisture laden gas from the re-breather environment, creating a combined gas mixture with relative humidity well within the operating range of commercially available CO2 detectors. CO2 measurements can advantageously be corrected by the venturi mixing proportions to gain a quantitative analysis of CO2 levels present in the pre-sampled 100% relative humidity condensing environment. The excess drive energy provided by the pressurized makeup gas allows for longer sampling lines that can be advantageously placed adjacent to the mouth of the re-breathing individual allowing CO2 measurement from a remote location and when drive gas is constantly applied, further allowing for continuous measurement of CO2.

A blown film die divides a flow of material into two flows with higher and lower flow portions and recombines the flow by combining higher flow portions with lower flow portions. The flow can be divided in circumferential channels between an annular feed ring and an annular distribution ring.
