Abstract: A pipe of thermoplastic polymer, e.g. polyvinylchloride is extruded.The wall thickness of the pipe is controlled in order to obtain a pipe of a substantially even wall thickness. For said control the wall thickness of the extruded pipe is measured at 360 points equally distributed over the circumference and moreover the average is determined in eight measuring sectors comprising 45 measuring points per sector. The average of the measuring values of one measuring sector is compared with the circumferential average of the 360 points, the deviation of the desired wall thickness in said one sector being counter balanced by the action of the heating elements.The apparatus of the invention for executing the method of extrusion of a pipe of thermoplastic polymer comprises an extruder with an extrusion die 2 having a moulding end part 2a and heating elements 11, 11' located about said end part 2a, and a wall thickness measuring device 7 being rotatably about the circumference of the pipe. The wall thickness measuring device 7 is transmitting measurement data to a signal processing unit 9. A comparator element 10 is provided for comparing two values of measurement values averaging operations and said comparator element 10 acts upon the temperature control device 8 controlling the temperature of the heating element 11 in a temperature control sector located in the axial extension of a measuring sector as compared with the average of the total circumference of the pipe.

Abstract: A filter element made of non-woven fabric formed as a folded package is self-supporting and is composed of thermally sealable non-woven fabric (1). Each of the two outer edges (3) of the folded package (2) is lined by the non-woven fabric material (1) forming the folds (4), which material, at each folded edge (3), is folded over in the same direction and is fixed to the corresponding bent edge of the adjacent end of fold in a tight fitting manner. The non-woven fabric material overlaps each bent edge of the adjacent end of fold by 1.5 to 2.5 times the fold separation. 
<??>To produce the filter element, the flat filter medium (1) is first folded and then a defined fold separation (7) is produced by a limited stretching perpendicular to the folding. The two outer edges (8) of the folded package are then positively clamped into comb-like sections (9) corresponding to the geometry and dimensions of the folds, and penetrating pincer-like into the folds on the upper and lower sides, the filter material projecting over the shaped sections (9) on each side by 1.5 to 2.5 times the fold separation (7). The overlapping material (10) is folded down on both sides in each case by means of a first pressing element (11) having a sideways action thereon, until the overlapping material (10) fits on the adjacent end of fold, so that the edges overlap. Energy allowing thermal sealing is supplied via these pressing elements (11). Further subsequent pressing elements (12) fix the sealed sites during cooling. The comb-like sections (9) are then removed and the folded package is contracted.

Abstract: A metered dose inhaler comprises a piston (3) which is mounted in a cavity (2) within a body (1), and is urged by a pre-loaded spring (6) into a reduced cross-section pressure chamber (4). The piston (3) may be loaded by means of an actuating rod (31) having a handle (32), and may be latched in a loaded position by a latching means (33). A liquid drug (e.g. in aqueous solution) is contained in a collapsible bag (10). Metered quantities of the drug are successively presented in the pressure chamber (4), and then subjected to a sudden and great increase in pressure, to eject the liquid drug through an atomising head (22), to reduce it to a fine atomised spray of small mean particle size - for example, less than 30 micrometres. Non-return valves (13 and 23) control the flow of liquid through the device. The sudden pressure pulse is caused by releasing the spring loaded piston (3), upon depressing an actuating button (35) connected to the latching means (33). <IMAGE>
