Title: Method of start-spinning a thread in an open-end spinning unit and machines for carrying out the method
IPC: D01H4/50
Filed: 1975-11-27
Abstract: 1530919 Open end spinners; starting spinning F STAHLECKER and H STAHLECKER 27 Nov 1975 [7 Dec 1974] 48786/75 Heading D1D In a method of starting spinning in an open end spinning unit, a thread end is returned to a rotating spinning rotor, is placed on a ring of fibres formed from individual fibres separated from a fed sliver and deposited in the rotor, and is drawn off again, wherein the method includes the preliminary steps of starting the sliver feed, and stopping the sliver feed, after which the feed is restarted after a given time to form the ring of fibres. To start spinning in rotor 9, Fig. 3, patrolling tender 6 is stopped at unit 7, and tender lever 44 depresses unit lever 21 to apply brake 15 to, and lift belt-pressing roller 14 from, rotor spindle 10. The drive to fibre supply roller 22, feeding opener 23, has been interrupted by clutch 26 actuated by stop-motion 30 upon thread breakage. Tender motor 41 drives tender wheel 48, engaged via a clutch with unit wheel 50, to rotate roller 22 for a predetermined time to give a preliminary fibre feed to produce ring 31 of fibres in the rotor. The preliminary fibre feed quantity varies with time as shown by lines 5a, 5b in Fig. 2, the initial quantity of fibres Q R  in the rotor depending on the time of decrease in the preliminary fibre feed upon the switching off of motor 41. When lever 44 lowers brake 15 and roller 14 to rotate the rotor, it actuates switch 45 which has a time lag relay. To start spinning during rotor acceleration, switch 45 actuates reversible tender rolls 34, 35 to feed thread end 33, picked from a winding cone by the tender, to trapper 47 which presents it to be sucked down withdrawal channel 32. Trapper 47 also resets stop motion 30, which does not actuate clutch 26 because member 52 actuates the switch. Switch 45 also actuates motor 41 so that roller 22 delivers fibres at a rate which increases approximately as the rota speed. After the start of spinning a timing element acting on member 52 causes, via switch 29, the clutch 26 to re-engage, tender member 51 causing slip in the drive from motor 41. Member 43 reverses rolls 34, 35 upon thread tension increase. The tender drive may not be used during start spinning, and member 52 is actuated to connect clutch 26 intermittently so that the fibre feed increases approximately as the rotor speed. Alternatively, Fig. 6, a trapper 69 traps the sliver fed to roller 22 upon thread breakage, and is controlled to intermittently trap the sliver by magnet 65 to allow fibre feed to accelerate as required during the start spinning. Roller 22, Fig. 4, may be driven from the tender via pivotable wheel 58 engaging unit wheel 57. Each side of an open end machine may be tended by a separate tender, or one tender may tend both sides of one or more machines.

Title: Dispensing from a container
IPC: B65D47/20
Filed: 1973-10-19
Abstract: 1453313 Dispensing fluent material CORNELIUS CO 19 Oct 1973 [25 Oct 1972] 48859/73 Heading A4T [Also in Division B8]  A closure for a container which is designed to be inverted and attached to a dispensing fixture is in the form of a diaphragm sealed to the container mouth and divided into peripheral and body portions by a circular line of weakness, connection of the container to the dispenser, causing co-operation between formations on the dispenser and one of the portions to produce relative movement resulting in severing the closure along the line. The body portion then drops on to a cooperating formation in the dispenser and defines with the peripheral portion a dispensing opening. In one form, a screw top container 20 having a lid 33 is sealed by a diaphragm 23 having lines of weakness 42, 43 and a frusto-conical embossment 60. The dispenser comprises a housing 36 into which is screwed the container mouth 21 and is fitted with an O-ring 39 which, in sliding past the container rim during attachment to the housing, frees the diaphragm along the lines 42, 43 so that it falls on to a boss 59 forming a rotatable part of the dispenser. The embossment 60 and boss 59 may have interfitting formations 64, 65 to prevent use of the dispenser with a container not having a corresponding closure. The container neck and housing may have similar complementary elements (not shown). The rotatable part has partitions 67 forming metering pockets 67a which discharge successively to a chute 68. Ribs 51 on the closure agitate the contents during rotation to facilitate discharge. The rotation may also assist in rupturing the closure or even be the sole means of doing it. In another embodiment, Fig. 9 (not shown), there is no rotary metering device and the released diaphragm has a conical embossment co-operating with a like-shaped spindle tip. The closure may be secured to the container by projections (31) on the container mouth engaging complementary apertures (30) in the closure flange (28) Fig. 5 (not shown). The projections and apertures may be arranged to form a product identification code. The dispenser collar 37 may have side openings 69 so that if an unsealed container is refilled and inverted on to the dispenser, the contents will spill out.

Title: Pulse frequency shifter
IPC: H03K5/13
Filed: 1972-11-06
Abstract: 1414654 Pulse frequency changing; automatic frequency control PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 6 Nov 1972 [9 Nov 1971] 51051/72 Headings H3T and H3A A frequency shifting circuit comprises: a delay stage 2 triggered by pulses in an input pulse train from a source 1; a voltage generator 4 which generates a sweep voltage which evenly varies the delay time of stage 2; and a coincidence detector 5 which detects when the time interval between an input pulse and a delayed output pulse from stage 2 is less than a predetermined time and then produces a signal which resets the sweep voltage to an initial value. If the sweep voltage sweeps from a low value to a high value, Fig. 2d, the pulses from the delay 2 are of increasing width Fig. 2b, and the spacing between the pulses of the output, Fig. 2e, is greater than that of the input pulse train. When coincidence occurs between an input pulse and a pulse from delay 2, at t n+1 , gating circuit 9 suppresses the next pulse generated in wavefine 2e to maintain a uniform spacing. If the output frequency is required to be higher than the input frequency, Fig. 3 (not shown) the sweep voltage is arranged to be from a high to a low value, and an extra pulse is added to the output pulse train when detector 5 detects coincidence. This is effected via the dotted path of Fig. 1. Where the output frequency is required to be higher or lower two circuits of the type shown in Fig. 1, 20, 21, Fig. 4a are arranged in cascade, and the sweep voltage may be applied to either. Alternatively, Fig. 4b (not shown), two separate input signals (32, 34) may be applied. Automatic control may be effected by feeding the outputs from the two units 20, 21 to an up/down counter 22, the output from which is fed to a digital/analogue converter 23. The output from converter 23 is then compared with a reference 25 in a comparator 24 to produce output signals which enable 20 or 21 depending on whether the output is two high or too low. The delay circuit.-Fig. 5 is a monostable comprising cross coupled transistors T 2 , T 3  both of which are conducting in the stable state. Application of a positive input pulse at T cuts off T 2 , T 3  and capacitor C 2  charges linearly from current source T 4 , R 5 , R 6 , R 7  until the potential at B turn T 3  on again. The unstable period is in part determined by the potential at C resulting from the control voltage Ust.
