Title: Extruder-mulling device
IPC: B29C48/67
Filed: 1956-08-16
Abstract: <PICT:0804821/IV (a)/1> An extruder-mulling device, e.g. for mixing colours with thermoplastic materials, e.g. nylon, and extruding films, comprises an extrusion screw 1, not mounted on thrust bearings, which with the extruder barrel 2 forms a channel in which the material is worked.  The said channel, which is fed via the hopper 4 and a feeder screw, communicates, forward of the screw 1, with a zone 14 which is enclosed by a stationary housing member 7 and a die member 13, and is shaped to contain a conical nosepiece 10, the apex of which faces the screw 1 and is detachably but rigidly connected thereto by the shaft 11.  In operation the rearward thrust of the screw 1 forces the conical surface of the nose-piece towards the corresponding surface on the housing and thus produces a mulling effect on the material therebetween which is then forced into the zone 14 and through the die outlet 15.  The die itself is formed by the housing 7 and the die member 13, and has an outlet valve 19 which regulates the mulling pressure.

Abstract: 953, 885. Measuring X-ray dosage. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 21, 1960 [July 24, 1959], No. 25459/60. Heading G1A. For measuring X-ray dosage a flat ionisation chamber of active area larger than the cross sectional area of the X-ray beam is connected to an instrument for measuring a quantity of electricity with at least one controlling member adjustable in accordance with the quality of the X-rays so that the quantity measured is dependent upon the ionisation current, the duration of irradiation and each adjustment or combination of adjustments of the member or members, Electrodes 5 and 6 of an ionisation chamber 1 are connected in series with a direct voltage source 9 and the current coil 11 of a kilowatt-hour meter. The voltage coil 13 of the meter may be connected by switches 20 and 21 to the contacts 14 and 15 of two potentiometers 16 and 17 respectively, which are connected across a source of direct voltage, which may be the source 9. The contact 15 is set according to the interelectrode voltage of the X-ray tube, whilst the contact 14 is set according to the particular filter used in the X-ray beam. The switches 20 and 21 may alternatively supply voltage to coil 13 from the contact 18 of a potentiometer 19, set according to the X-ray tube voltage only. The quantity measured is indicated in terms of absorbed dosage by prior calibration of the device. In another embodiment, Fig. 2 (not shown), the potential to which a capacitor is charged by the ionisation chamber is determined by means including a direct voltage amplifier with controllable degenerative feedback networks serving the same purpose as the controls 14,15 and 16.

The melt flow index of plastics material is determined by the time taken for a loaded piston to extrude a measured quantity through a hole of known diameter. As shown, the piston 5, attached by rod 6 to a platform 8 carrying weight 9, is located in a test cylinder 2. Plastics material produced in a machine 12 is forced past a valve 13 into the cylinder 2, raising the piston 5 and platform 8 until it trips a switch 15 to prepare a time switch 16 and close valve 13. When the temperature inside cylinder 2 reaches a predetermined value, switch 16 releases catch 14 and the piston 5 falls, forcing the plastics out through a nozzle 4. The time taken to fall is measured by two switches 17, 19 which start and stop respectively a motor-driven potentiometer 18, the end position being shown on a recorder 20, whose sensitivity, or the speed of the motor, is adjusted at 21 in accordance with the known density of the material at the preset temperature. The test is continuously repeated and the results may be used to control machine 12.
