Title: Improvements in or relating to means for measuring yarn in pirn and like winding-apparatus
IPC: B65H63/08
Filed: 1933-11-07
Abstract: 428,372. Measuring stop-motions. BRITISH CELANESE, Ltd., 22, Hanover Square, London, ARMETT, G. A., BLACK, A, P., and FULTON, S. M., c/o British Celanese, Ltd., Spondon, near Derby. Nov. 7, 1933, No. 30925. [Class 120 (ii)] A measuring stop-motion for pirnwinding and like machines comprises a rotatable member, preferably a notched disc, driven at a predetermined rate relatively to the winding spindle, and a member under the control of the rotatable member and adapted to be directed into the path of the traversing mechanism so as to operate a stop-motion after a pre-determined number of revolutions of the winding spindle, said member preferably being a weighted or spring-loaded lever which rests on the periphery of the notched disc. The winding spindle may be in geared connection with the notched disc, and the gears may be interchangeable. A number of winding heads in one machine may have a common drive for the notched discs, and each winding head may be stopped by its notched disc independently of the others, e.g. the discs may be frictionally driven, and the means actuated by the disc to stop the spindle may also disconnect the friction drive to the disc. The winding spindle 12 drives the notched disc 27 through reduction gearing 13, 14, 19, 20, 18, 22, 24, 25. The spindle 15 carrying the worm wheel 14 is pivotally mounted in a cradle 17 so that the gear 14 may be replaced by different size gears. When the notch in the disc 27 comes below the pivoted lever 33, the latter drops and causes the wire 35 to assume the dotted line position, Fig. 4, whereupon the abutment 36 on the traverse rod 37 drives the wire against the arm 38, which rotates the lever 39 and withdraws the latch 41 from the arm 42 on the starting and stopping rod 43, whereat the latter rotates and winding ceases. The wire 35 is prevented from actuating the stop-motion when the machine is restarted and before the lever 33 has regained its normal position by means of a stiff wire attached to the traverse mechanism (not shown) which passes between the wire 35 and the abutment 36, and which is gradually withdrawn as winding proceeds. In a modification, Fig. 5, there is a common spindle 51 for all the notched discs of a number of winding heads. Each disc is mounted freely on the shaft 51 and is frictionally held between collars 53, 54. When a disc completes one revolution, the lever 57 drops into the notch and the wire 60 is engaged by the traverse mechanism to stop the winding spindle as described with reference to Fig. 4 ; this causes the stopping rod 43 to rotate, whereby the links 62, 63 rotate the lever 64 pivoted at 58, the arm 65 of which displaces the spring- loaded collar 54 and so stops the drive to the disc. In order to positively stop the disc, notwithstanding the continued rotation of the shaft 51, a projection 67 on the disc is engaged by an arm 66 on the lever 64 until the latter is returned to its normal position.

Title: Cap seals for containers
IPC: B67B5/03
Filed: 1972-07-03
Abstract: 1430090 Cap seals for containers HAYWARD PLASTICS Ltd 2 Oct 1973 [3 July 1972] 31040/72 Heading B8T A method of applying cap seals to containers, e.g. bottles, comprises the steps of providing a flattened tube 1 of heat-shrinkable plastics material which is partially severed at regular intervals to define individual cap seal sections, feeding the tube 1 on to a mandrel 13 with which acontaineroap is axially aligned, totally severing the leading cap seal section from the remainder of the tube on the mandrel, feeding that section from the mandrel over the container cap and applying heat to cause the cap seal section to shrink on to the container cap. In carrying out the method, the containers, e.g. bottles, are conveyed intermittently on a belt to bring successive containers into alignment with the mandrel 13. A previously severed leading cap seal section 1 is held by friction on a leading end 14 of the mandrel. The rest of the tube passes downwardly to the mandrel via a flat blade 11, a tube expanding cone 12, and a main mandrel part 13. The operating head, including sleeve gripping jaws 17 and cutters 18 moves down with the mandrel towards the container. The leading end 14 is stopped by the top of the container but the jaws 17 and cutters 18 continue downwardly to position the seal section 1 on the container. The seal section 1 is held on the container by friction. The jaws 17 release a mandrel sleeve 16 which returns under the action of a spring and is then located within the section 3. The operating head now moves upwardly and supporting arms 19 thereof engage the core 12 and move the mandrel upwardly. The jaws 17 clamp the seal section 3 to the sleeve 16 and the cutters 18 operate to sever the seal section 2. The conveyer is advanced to bring the seal section bearing container beneath a vertically reciprocating heater to shrink the section on to the container. The plastics tube 1 is partially severed transversely to leave frangible connections 4. The tube is preferably provided with a pair of longitudinally extending parallel perforations 2 to define a tear-strip 3 for each cap seal to facilitate removal from the container. The tube is preferably of polyvinyl chloride.

Title: Improvements in and relating to centrifugal machines
IPC: B04B11/02
Filed: 1945-11-20
Abstract: 602,069. Centrifugal machines. WERKSPOOR, N. V. Nov. 20, 1945, No. 31218. Convention date, Nov. 22, 1940. [Class 23] Two components of a liquid mixture either or not contaminated by solids are continuously separated in a centrifugal machine in which the supply to the machine is controlled in dependency of the position of the boundary plane between the two components, the control being effected by a liquid surface that establishes itself during operation, concentrically around the axis of rotation, in a space of the rotor which space under normal conditions is accessible to the heavy component only. In the apparatus shown in Fig. 1, the mixture is supplied through a valve 24 and a central tube 7 to a rotor comprising a central part 3 and a number of conical parts 4. The upper part of the rotor supports an imperforate conical disc 6 by means of radial webs 25 and the disc 6 carries a perforated cylindrical part 12 surrounded by a series of perforated conical discs 13. The lighter component of the mixture is collected by the scoops 10 and discharged through tube 8. The heavier component is discharged through exhaust ports 5 and also establishes a liquid surface 17 in the neck 16 of the rotor to effect the control of the supply of mixture to the apparatus through a non-rotatable pivoted float 20, arm 19, rod 21 and arm 22 operating the balanced valve 24. When the surface of separation 15 moves outwardly, the liquid surface 17 moves automatically in the same direction thus causing the valve 24 to open to admit an increased supply of mixture. In a modification, which gives better separation and more accurate control, the liquid surface 17 effects control of the supply of additional heavy liquid, instead of the supply of the mixture. In Fig 4, the additional heavy liquid is supplied under low static head through the inlet 33 to a stationary chamber 31 the periphery of which is composed of a number of vanes 32 inclined against the direction of rotation of the rotor to ensure the supply is cut off when the surface 17 reaches the outer circumference of the vanes. Alternatively, the control of the supply of additional heavy liquid is effected by a float arrangement similar to that shown in Fig. 1.

Abstract: 650,666. Colour television. STANDARD TELEPHONES & CABLES, Ltd. Nov. 26, 1945, No. 31820. Convention date, Jan. 13. [Class 40 (iii)] In a colour television system, the framesynchronizing pulses corresponding to frames of any one component colour differ in width from the synchronizing pulses corresponding to frames of a different component colour. It is also stated that the pedestals of the framesynchronizing pulses may be used to carry further pulses conveying additional information, e.g. the accompanying sound channel, by modulation of the timing of these pulses with respect to the leading edges of the synchronizing pulses. Transmitter. A generator delivers a pulse f, Fig. 2, at the commencement of each complete colour cycle. In a tricolour system, the pulse f is applied to three delay networks, each of which delays the pulse by the amount appropriate to its respective colour channel to produce pulses g, i, k. These are applied to trigger circuits which produce pulses h, j, l of predetermined and differing widths. These signals are combined in a mixer with the three colourcomponent video signals from a television camera. The horizontal-synchronizing and vertical-pedestal. signals are also introduced into the mixer, the composite output signal, which is as shown at a, Fig. 4, being passed to a transmitter. Receiver. The signal a, Fig. 4, is limited, as at b, differentiated, as at c, and limited again to produce pulses d which are used for horizontal synchronization. The signal b is also applied to three width discrimination circuits, as described in Specification 592,789. The outputs of these circuits shown at e, f, g are applied in pairs, i.e. ef, fg, ge, to three trigger circuits which produce pulses h, i, j respectively. Each of these is applied, together with signal a, to a separate mixer, each of which produces a signal such as is shown at k. The mixer outputs are limited to give the signals l, m, n, so that the received signal is separated into three channels corresponding to the channels at the output of the camera. The Specification as open to inspection under Sect. 91 also states that the lines of successive frames are so interlaced that in nine successive frames each line of three adjacent line positions is used once only for each primary colour. This subject-matter does not appear in the Specification as accepted.
