[Also in Division G4] A fluid flowmeter comprises a rotor 10 mounted in a duct 11 for rotation by fluid-flow and by an electric motor 16, the pressure drop across the rotor providing a signal to a controller 28 which varies the motor speed to bring the pressure drop to zero whereby the motor speed is a measure of flow-rate and is sensed by a pick-up 17 and frequency meter and counter (not shown) which latter measures total flow. The pressure sensor includes a diaphragm 21, responsive to pressure difference between pipes 24, 25 at rotor inlet and outlet pressure respectively, and coupled by rod 26 to a position sensor 27. The rotor is a centrifugal impeller. In an alternative embodiment Fig.2 (not shown) an axial flow turbine rotor (30) is used and the motor 16 is a stepping motor to which the frequency of supply voltage pulses is controlled in accordance with pressure drop as before. A further embodiment (not illustrated) uses a pivoted plate mounted downstream of the rotor and responsive to the helical angle of swirl of fluid leaving the rotor. The pivot shaft of the plate carries a device which controls motor speed and hence turbine speed to bring the helical angle to a predetermined valve representing zero pressure drop across the rotor.

Abstract: 1380760 Rotary positive-displacement machines AGINFOR AG FUR INDUSTRIELLE FORSCHUNG 11 Dec 1972 [10 Dec 1971] 56980/72 Heading F1F A rotary positive-displacement machine comprises a displacement chamber divided into two sections 10, 11 each section having a partcylindrical ring-shape and being defined by an inner convex surface 23, 24, an outer concave surface 22, 25 and axial end plane closure surfaces. The sections are joined by a passage 15 and section 10 has inlet 13 and section 11 has outlet 18. A displacement device comprises two rigidly interconnected vanes 20, 21 of part-cylindrical ring- shape, the device being rotable in a circle so as to move the vanes in a circular motion in direction 33. The vanes and chamber sections each extend over 270 degrees and are displaced in orientation with respect to each other by 90 degrees. In Fig. 1 vane 20 is shown as contacting the inner and outer walls 23, 22 at points 29, 30 respectively whilst vane 21 touches only the outer wall 25 at point 31. Thus there is flow communication between passage 15 and outlet 18 whilst vane 20 blocks off inlet 13 from passage 15 and acts alone as a pumping or driving member. Fig. 2 shows the situation after movement in direction 33 of the displacement member through 45 degrees. Here the vane 20 contacts only the inner surface 23 at point 29, thus permitting through flow from inlet 13 to passage 15, but communication between passage 15 and outlet 18 is cut off by vane 21 which  engages both walls 24, 25 at points 32, 31 and thus acts as the pumping or driving member. Other embodiments employ three vanes and three chambers Figs. 3 and 4 (not shown), two pairs of vanes and chambers arranged in parallel, each pair being of the type shown in Figs. 1 and 2, Fig. 5 (not shown), two vanes in each chamber Fig. 6, (not shown), and a machine of the type in Figs. 1 and 2 but with the chambers arranged axially in a stacked construction Fig. 7, (not shown).

Abstract: 1,144,830. Extrusion; polyamide filaments. E. I. DU PONT DE NEMOURS & CO. 19 Dec., 1967 [21 Dec., 1966], No. 57567/67. Headings B5A and B5B. [Also in Division B1] Polyamide, e.g. polyhexamethylene adipamide, is extruded by a screw extruder having a melt zone along which the pressure increases, a fraction of the melt being constantly recirculated from the high pressure to the low pressure region. In this way thermal degradation is reduced together with the necessary driving torque. In the embodiment shown in the Figure, the increase in pressure is effected by the reverseflighted portion 56 of the screw 50 and the material is recirculated through a pipe 40 fitted with pressure transducers which enable the pressure difference to be ascertained at any time. The melt zone includes a kneading region 54. In the embodiment illustrated in Fig. 1 (not shown), the extruder is connected to a spinneret and the resulting filaments are gathered into a thread-line through a ring guide and are finally wound on to a storage reel.

IPC: B29D30/06
Filed: 1966-12-28
Abstract: 1,176,668. Heating and cooling tyre vulcanization presses. SVENSKA GUMMIFABBIKS A.B. 28 Dec, 1966 [28 Dec., 1965], No. 57992/66. Heading F4U. A tyre vulcanization press is heated by a hot water circuit and cooled by a cold water circuit, both circuits being maintained at constant pressure by the application of steam to the hot water circuit. As illustrated, the hot water circuit comprises a pump 16 circulating water through a steam heated indirect contact heat exchanger 17 and the press it. A press by-pass 21 is provided to allow regulation of flow through the press while maintaining constant flow through the pump, and to accept the whole of the hot water flow when press cooling is required at the end of a vulcanizing operation. Steam supply to the heat exchanger 17 is controlled by a valve 30 in response to temperature sensed in a chamber 31 connected to both the flow and return lines of the circuit. Steam is also supplied through a line 40 to maintain a constant pressure in a pressurizer 18. A small amount of water is supplied to the pressurizer over degassing baffles 26 by the pump 16. Since the steam supplied to the pressurizer will be hotter than the required water, temperature, water is withdrawn from the pressurizer at an intermediate level 24 to avoid drawing off the overheated surface layer. If a level senser 28 indicates that make up water is required, this is supplied by a pump 3 from a tank 1 which is heated by a preheating steam supply pipe 4. The tank 1 is in turn supplied from a tank 5 which receives fresh water through a pipe 7 and return water through filters 9. The cold water circuit includes a pump 13 and two coolers 12. The circuit is pressurized by the provision of a connection 27 with the make up line of the hot water circuit.
