Abstract: 1,249,247. Tension arrangements. MASCHINENFABRIK RIETER AG. 9 Dec., 1969 [9 Dec., 1968], No. 59930/69. Headings DID and D1J. The tension in a yarn taken at constant speed from an open-end spinning device is controlled by gauging the yarn tension and varying the difference between the take off and winding speed accordingly. As shown, open-end spun yarn 2 is passed over tension sensing arm 4 over fixed guides 5 and 6 and traversed onto the package 8 which is driven by drum 9. The drum 9 is pivotally mounted and rests on a friction driving ring 12 which is axially movably position on drive roll 10. The speed at which the drive roll 10 drives the package drive drum 9 is determined by the axial position of friction ring 12. The position of this ring 12 is varied by the tension sensing arm 4 acting via extension 23 and fork 15. There is a minimum tension variation required before the speed of the drive drum 9 is increased as determined by the distance between extension 23 and the coacting stops 17, 18 on the fork 15. In alternative embodiments, (a) the tension sensing arm is attached directly to the fork 15 (Fig. 4); (b) the sensitivity of a plurality of winding mechanisms is varied from a central point via a rod and springs attached to the forks 15 (Fig. 5); (c) the fork 15 is moved in either sense (so as to move the friction ring 12) by a lead screw device which can be moved to bring it into contact with one of two oppositely rotating rolls (Figs. 6 and 7); (d) when the yarn breaks the extreme movement of the fork can be terminated by a lifting device (Figs. 7 and 9) or a slipping clutch; (e) the yarn tension is varied according to the size of the package with or without other variations being superimposed (Fig. 10); the yarn tension is maintained constant with a decreasing contact pressure of the package on the bobbin as the package grows (Fig. 11). The yarn take off speed can be varied instead of varying the winding speed.

Abstract: 1,248,450. Thrust reverser. SAAB-SCANIA A.B. 23 Dec., 1968 [27 Dec., 1967], No. 60931/68. Heading B7G. An aircraft with wing-mounted by-pass turbo-jet engines 5 may be braked by deflecting exhaust gases solely upwards and forwards over the wing 4 to form a gaseous screen 14 extending across part of the span of the wing thereby preventing the ingestion into the engine of exhaust gases and ground debris. The aircraft has four engine nacelles 5 mounted on the underside of the wing each having a jet pipe 8 and a reversing exhaust gas duct 9 which extends forwardly and upwardly through the wing 4. Downstream of the gas duct 9 in the jet pipe 8 are a number of reversing flaps, actuated by hydraulic cylinders (not shown) which swing them from a position in which they continue in the wall of the jet pipe and close the reversing outlet to one in which the open reversing outlet can wholly or partly close the jet pipe 8. The reversing gas ducts 9 from one wing 4 are shaped into a single pressure chamber 29 which extends spanwise of the wing and leads to a slot 13. The pressure chamber is covered and bounded by a flap 30 pivotable about its trailing edge by hydraulic cylinders 31 from a position in which the flaps merge with the wing and close the pressure chamber to a raised position in which a step 32 is formed to ensure that the deflected exhaust gas does not subject the top of the wings to excessive heat. In the embodiment of Figs. 8 and 9 (not shown) the engine nacelles (5a) are attached to the wing (4) by a pylon (36). The wing has a passageway 91c for exhaust gases which is normally closed by hydraulically operated flaps (37, 41) and which contains a number of fanwise arranged guide rails (43) to diverge the exhaust jet spanwise. A shutter 39 is hingedly mounted and pivotable by a jack 40 to close an outlet 9a of the nacelle. When the apparatus is in the thrust-reversing position shutters 39 and 41 combine to form an outlet part 9b which is bounded only by a front and rear wall and lacks sidewalls.

Patent GB-647640-A (GB)
IPC: H02P3/12
Abstract: 647,640. Control of D.C. motors. STEVENS, A. H. (Submarine Signal Co.). Sept. 11, 1944, No..17305. [Class 38(iii)] Means for dynamically braking an electric motor comprise a shunt circuit across the motor terminals with a resistance and gaseous-conduction tube in series, said gaseous-conduction tube having a control grid element and means including normally-closed switch means arranged to connect a bias potential source to said tube and normally negatively-biassing said grid control element during the operation of said motor, said switch means being opened for removing said bias to provide dynamic brake action for said motor. As shown, a direct-current motor 1 is supplied from an alternating-current source through a gridcontrolled gaseous rectifier valve 3, and switches A, B are closed simultaneously to bias negatively a control tube 64 and pass current to the motor through the rectifier 3. When the switches are opened, the negative bias is removed from the valve 64 and the valve 3 is biassed so as to stop the motor rapidly. When contacts B are opened, no potential obtains across resistor 61 in the grid circuit of valve 64 and the motor armature is therefore shunted through this valve and resistor 66. With the simultaneous closure of contacts A, B, a negative potential is applied to grid 68 to open the armature shunt circuit since rectifier 62 now passes current through resistor 61. The grid 11 of the control valve 3 is controlled by a time-delay circuit, whereby the current passed by the valve increases at a desired rate on starting, which is similar to that described in Specification 636,661. A resistor 47 furnishes a negative bias component for the grid of a section 37 of a twin triode tube TT. Rectified current is supplied to this resistor by means of valve 49 the grid 51 of which is controlled through a diode valve 52. Current is maintained through the diode 52 and a condenser 59 is charged when contacts A are opened and a potential is developed across resistor 55. The grid 51 is then maintained at a negative potential, no potential is established across resistor 47, and triode section 37 pases current which blocks the rectifier valve 3. However, upon closure of switch A, the resistor 55 is short-circuited and condenser 59 discharges through resistor 58, the valve 51 gradually establishing a potential across resistor 47 to cut off the triode 37 and close the motor circuit through the valve 3. Continued operation is controlled by positioning taps 45, 48.
