Title: Method and apparatus for obtaining predetermined lengths of shirred casing
IPC: B65B9/18
Filed: 1969-04-08
Abstract: 1,261,760. Shirring casings. UNION CARBIDE CORP. 8 April, 1969 [8 April, 1968], No. 17843/69. Heading A2B.  A method of producing predetermined lengths of shirred tubular casing comprises feeding by means 30 an inflated casing 14 over a shirring mandrel 12 and through a shirring head S, measuring a predetermined length of casing fed to the shirring head S, placing an indicator 40 or 40' at the end of the measured length as it leaves the shirring head S, advancing the shirred casing 18 with the indicator through retarding means 32 to loosely compact the shirred casing 18 whilst measuring and shirring a succeeding predetermined length of casing, severing the loosely compacted casing 18 at the point, indexed by the indicator, and returning -the indicator to a point adjacent the shirring head S to be ready for another measure length. The severed shirred casing may be compressed into a casing stick 19. The method may comprise the use of one or more than two indicators. The casing may made of collagen, cellulose, regenerated cellulose, polyolefin, starch or alginate. In the embodiment shown the mandrel 12 is hollow and air is passed therethrough to inflate the casing. The feed means 30 and retarding means 32 each comprise a pair of driven belts. Each indicator 40, 40' is mounted on a slide carriage 42, 42' slideable along a rotatable splined rod 44, 44'. The rods 44, 44' are rotated to bring the indicators 40, 40' into and out of contact with the casing at the appropriate times under the control of a cam 50 which is connected through a gear box 64 to the means driving the feed belts 31 so that the cam is rotated at an appropriate speed in relation to the casing speed. In use when a predetermined length of casing has passed through the shirring head S the cam 50 is in a position to allow a spool 56 or 56' to position itself in a spring loaded air valve 54 or 54' to allow passage of air to a spring loaded cylinder 46 or 46' resulting in an indicator 40 or 40' engaging the shirred casing. When the casing has been cut the raised portion of the cam 50 forces the spool 56 or 56' into the valve 54 or 54' so that the cylinder 46 or 46' is exhausted, resulting in the indicator 40 or 40' being disengaged from the casing. The disengaged indicator is returned manually or automatically e.g. by pneumatic, electrical or hydraulic means or under gravity, to a position adjacent the shirring head S ready to index another measured length. The cam 50 is rotated half a revolution for each measured length so that the indicators are used alternately to index a measured length.

Title: Improvements in yarn retrieving apparatus for winding machines
IPC: B65H67/08
Filed: 1961-05-18
Abstract: 969,773. Winding yarns. LEESONA CORPORATION. May 18, 1961 [May 19, 1960], No. 18121/61. Heading D1J. The invention relates to a winding machine of the kind in which a package P, Fig. 2, is wound in one position until the package strand is broken or exhausted and in which the package P is then moved on to a rest plate 51 to bring it to a halt and finally on to a reverse roll shaft 20 to cause a length of strand to be unwound from the package so that said unwound length of strand can enter a vacuum compartment 100 where it is caught by a beak member for transfer to a knotting device where said strand end is then connected to a fresh strand end. According to the invention the vacuum compartment 100 has a cover 108, Fig. 4, shaped to form a first elongated slot 112 in the region of the reverse roll shaft 20 and into which the strand end can be sucked, and a second slot 114 through which the beak 78 (not shown) is able to enter the compartment 100, the slots 112 and 114 being closable by a sliding valve 118. In operation, the mechanism that causes the package P to engage the rest plate 51 and then the reverse roll shaft 20 also causes the sliding valve 118 to move firstly to the left to uncover the slot 114 and permit the beak 78 to enter the vacuum compartment. Thereafter the sliding valve 118 moves rearwardly away from the package P and to the right to uncover the elongated slot 112 and close the slot 114, the rearward movement of the valve 118 leaving a small opening through which the arm carrying the beak projects into the slot 114. Since the elongated slot 112 is now open the end of the strand on the reversely driven package P is sucked into the slot and then to the right to extend across the beak 78 therein. The valve 118 then slides to the left to uncover the slot 114 to permit the beak to be swung out to present the strand end to the knotting device 70. Thereafter, as the package P is moved back to its winding position the valve 118 slides forwardly and to the right to close nozzle 112 and slot 114. The closure valve 118 is constructed from a thin flexible material so that the suction in the compartment 100 will draw the closure tightly against nozzle 112 and slot 114 to provide an efficient seal. A finger 184 and a notch 180 in a plate 174 serve to guide the strand on to the periphery of the package P after it has been retrieved by suction nozzle 112 and ejected from slot 114 by the beak 78. Specifications 704,931 and 969,776 are referred to.

Abstract: 343,855. Hydraulic shock-absorbers. AKTIEBOLAGET SVENSKA STÍTDAMPAREFABRIKEN, 81, Birgerjarlsgatan, Stockholm.-(Assignees of Everstam, J. G. and Everstam, E. A. ; 19, Surbrunsgatan, Stockholm.) June 13, 1930, No. 18139. Convention date, June 13, 1929. [Class 108 (iii).] Shock-absorbers for motor vehicles of the type in which a cylinder is enclosed in a reservoir and the movements of the piston into the cylinder are opposed by fluid friction, are constructed with a flute or channel in the wall of the cylinder and connecting t h e interior thereof to a relief port, the piston being adapted to cover the flute progressively during inward movement so as to increase its effective length and hence the resistance to movement. The piston 5 is moved upwards by a spring and downwards by an arm 20 carried by a spindle 21 which projects outside the main casing 1 and is oscillated by an arm 22 and a connection 23 to the axle. A non-return valve 7 in the base of the cylinder allows substantially free upward movement, but during downward movement liquid can only escape from the cylinder through that part of a helical recess 8 which lies between the lower end of the piston and the relief valve 10. As the piston moves downward it covers an increased length of the helical recess and the resistance to escape of the liquid is increased correspondingly. The end of the arm 20 engages the upper end of the piston through a plate 18 having a sliding movement limited by engagement of the pin 17 with the ends of the slot 16. A further relief passage 19 may be provided in the plate 18 or in the end of the piston.

Abstract: 690,055. Baking apparatus. SCRIBBANS-KEMP, Ltd., BARSBY, C. R., CHAYTOR, H. C., CLAYTON, W., HENDON, A. L., and SUMNER, C. G. July 19, 1951 [July 21, 1950], No. 18259/50. Class 28 (i). Sponge cake, or the like, is baked in a continuous sheet and is delivered as a succession of inverted cut pieces on to a conveyer which carries them forward for further treatment in the same direction as that of the sheet during baking. Baked sponge material 1, Fig. 1, supported on steel band 2, emerges from baking chamber 3 and passes under blade 4, which cuts it into lengths that remain adherent to the band 2 and are carried round terminal roller 6. As each piece of sponge material 7 reaches a predetermined position, it is detached from band 2 by a resiliently mounted blade or taut wire 8, operated by cam mechanism 10, and falls on to conveyer 9. Alternatively, the sponge material may be cut after passing round roller 6. As shown in Fig. 2, sponge material passes through a cooling tunnel 16 and round a roller 17 on to a transfer conveyer 18 on which it is cut, by blade 19, into pieces 20. Each piece 20 passes on to a plate 11 and when it reaches a stop the plate is moved rapidly horizontally allowing the piece 20 to fall on to conveyer 14. In a further embodiment (Fig. 4, not shown), the sponge material, after cutting, is passed round a terminal roller against which it is held first by a fixed guide and then by a movable guide. The latter is removed at intervals to allow the cut pieces to fall on to a second conveyer.
