Collapsible tubes are gripped at the open end and trimmed to length and then forwarded between guide means to a heat sealer which fuses the portion of the tubes projecting above the guides. The tubes, fed by means not described, pass between jaws 1, 2 having pins 3, 4 slideable in a groove 8 in a fixed member 9 and grooves 5, 6 in a vertically moveable plate 7. As the plate descends the jaws move in to flatten the tube end and a bell-crank 10 is rotated by a stop 13 on an extension of the plate to cause a blade 16 to shear off the protruding margin. The tubes then pass between rails 21, 22, their movement being assisted by rollers 24, 25. The source of heat (not shown) is above the rails and may be a high frequency device. The gap 23 between the rails is adjustable for various tube thicknesses. The rails may house cooling means.

Title: Improvements in and relating to flyer frames, particularly for drawing and twisting slivers
IPC: D01H1/36
Filed: 1938-06-07
Abstract: 515,627. Flyer frames. HAWORTH, H. V. June 7, 1938, No. 16848. [Class 120 (ii)] In a flyer frame for drawing and twisting sliver of cotton or other material, either natural or synthetic, into roving or yarn and winding it into the form of roving bobbins, cross-wound cheese bobbins, or on to double-flanged bobbins, the bobbin is rotatably mounted on a revolving spindle and is alternately and intermittently driven at the same speed as the flyer and at a speed that exceeds that of the flyer. As shown, the bobbin whorl b is smaller in diameter than the spindle whorl a and both whorls are driven by a single tape or band E from the tin cylinder F; a cylinder j with a stepped helical groove j' in its periphery is spliced on the spindle A within the bobbin carrier B which has one or more pegs b<5> engaging the groove j<1> and the foot of the cylinder j is carried by a table J which passes through the bobbin carrier and is supported by a ball bearing in a rail L which is movable on the spindle A. When the peg b<3> engages with a step of the groove j' the speed of the bobbin is the same as that of the spindle A and the flyer H and the belt slips on the bobbin whorl b but as the peg moves away from the step, winding takes place through the whorl b being driven by the belt at a speed higher than that of the flyer. The rail L and the bobbin rail D are traversed together by the usual roving frame gear which also gives the rail L an up and down movement corresponding to the depth of the steps of the groove j<1> and with the same relative speed variation as is given to the rail D to allow for the increase in the diameter of the yarn package on the bobbin. The band E is tensioned' by a pulley G and guided by a pulley a<1> and by pulleys b', b<2> which reciprocate with the bobbin rail. The drawing-rollers are arranged in three tiers the upper two Q being used for laps or heavy slivers, and the lowest comprising four or five lines of rollers similar to those of a high-draft roving frame. Specification 514,519 is referred to.

Abstract: 1,270,837. Safety devices for jib cranes. BROWN BOVERI & CO. Ltd. 1 April, 1969 [3 April, 1968], No. 16949/69. Heading B8B. [Also in Division G1] A bearing block for a luffing jib crane comprises a pulley shaft 2 supported at each end by a plate 3 having a central web 9 attached to the plate by two integral, flexible web strips 7, 8. The strips define vertically-disposed slots 5, 6 while the central web is spaced vertically from a lower region of the plate by a horizontally disposed slot 4. In use, application of a horizontal component of crane load G to the pulley shaft, caused, for example, by swinging of the load, causes a horizontal deflection of the strips 7, 8 and consequent variations of the widths of the slots 5, 6. Similarly the vertical component of crane load produces a variation in the vertical width of the horizontally-disposed slot 4. Electrical signals proportional to such variations are produced by transducers (not shown) for example a solenoid of which the inductance is proportional to the vertical width of the slot. The signals enable calculation of the weight G and the deviation from the vertical of the load lifting rope. Further it is stated that the signals may be used for warning or control purposes to prevent the crane toppling.

The filling head preferably includes a protuberance 14 carried by a sleeve 4 slidable in the filling head, whereby upward movement of the sleeve lifts the ball 3 from its seat 2 to allow flow of cleaning liquid through the head. The sleeve 4 is of smaller diameter than the inside of the head 1 to allow cleaning liquid to flow between the sleeve and the inner wall of the head. The sleeve includes grates 7 to reduce foaming of the product to be filled and the sleeve is held in the head by an annular seal 10. The collector is clamped to the flange 15 of the head for cleaning and thus a bar across the collector pushes against the sleeve 4 to raise the sleeve and thus the ball 3. In an alternative embodiment, the protuberance is carried by a drum slidable in a socket attached to the head by a screwthreaded collar. A filling machine including a plurality of filling heads may be operated for cleaning by means of individual collectors attached to each head or by means of a common collector simultaneously operating on a plurality of filling heads.
