Abstract: The invention relates to an adjusting device (10) for controlling a discharge thickness (AD) of a nozzle discharge slot (110) of a flat film machine (100), comprising a plurality of adjusting bolts (20) for carrying out an adjusting movement for changing the discharge thickness (AD), wherein the adjusting bolts (20) comprise an adjusting region (SB) between a closing end position (SE) and an opening end position (OE), wherein further starting from the opening end position (OE), the adjusting region (SB) comprises a basic stroke path (BH) for a basic adjustment of the discharge thickness (AD) and, starting from the closing end position (SE), comprises a process stroke path (PH) for process controlling of the discharge thickness (AD).

Abstract: The invention relates to a method for controlling a thickness profile (DP) of a film track (FB) along a transverse direction (QR) by means of a plurality of adjusting means (120) for adjusting a slot opening (112) of a discharge nozzle (110) of the flat film machine (100), comprising the following steps: acquiring a thickness profile (DP) along the transverse direction (QR) of the film track (FB) transverse to a production direction (PR) of the flat film machine (100), comparing at least a partial section of the acquired thickness profile (DP) with a preset profile (VP), determining at least one local profile deviation (PA) in a deviation section (AA) as a result of the comparison, generating at least one controlling intervention for the adjustment of at least one adjusting means (120) in an intervention section (EA) different from the deviation section (AA).

Abstract: A polyethylene composition particularly suited for producing blow-molded hollow articles, having the following features: 1) density from 0.948 to 0.955 g/cm3; 2) ratio MIF/MIE from 60 to 120; 3) MIF from 15 to 45 g/10 min.; 4) ER values from 2 to 5.0; said composition being obtainable by contacting a precursor polyethylene composition with a radical initiator.

Abstract: A polyethylene composition particularly suited for producing blow-molded hollow articles, having the following features: 1) density from 0.948 to 0.960 g/cm3; 2) ratio MIF/MIE greater than 125; 3) MIF from 20 to 40 g/10 min.; 4) ER values from 5 to 10.

Abstract: The invention relates to a method for automatically regulating the size of a nozzle discharge slot of a nozzle assembly, wherein the nozzle assembly comprises a first and a second nozzle lip and a nozzle discharge slot arranged between the nozzle lips for setting in a controlled manner a thickness profile of a conveyable melt. A plurality of adjusting elements, in particular a plurality of adjusting pins, coupled to a respective thermoelement, is arranged on the first nozzle lip, the thermoelements being controllable by the regulation in such a way that the slot can be adjusted by the action of a mechanical force from the respective adjusting element on the first nozzle lip, as a result of the expansion or contraction of the thermoelements. At an initial operation of the nozzle assembly for conveying the melt, the adjusting elements for subsequent regulation of the slot size are set uniquely free from play as the initial setting. The invention further relates to a control and/or regulation system.

Abstract: A method for analyzing water or other liquid, in particular rain water, comprises the steps of providing a collector comprising at least first and second volumetric cells and a mechanism for causing water to flow selectively into the cells and for causing water to flow selectively from the cells. Water is caused to flow into a first one of the cells while it is prevented from flowing into the other one of the cells. The water collected in the first cell is caused to flow to a property determining cell when the first cell has been filled to a predetermined volume, and simultaneously water is prevented from flowing into the first cell while it is now permitted to flow into the second volumetric cell. The water collected in the second cell is then permitted to flow to a property determining cell when the second cell has been filled to a predetermined volume, and simultaneously the water is prevented from flowing to the second cell while it is now permitted to flow to the first cell.
