Title: Yarn piecing and knotting devicing for spinning apparatus
IPC: D01H15/00
Filed: 1977-06-22
Abstract: Two suction pipes (1, 2), which work on the jet-pump principle, are connected to a compressed-air pipe (5). A storage pipe (4) is provided with a yarn-suction orifice (4b) and is connected to a vacuum source (13) via a conduit (9). The yarn, which is spun by a spinneret (15) and which is guided to a yarn body (19) by a drawing-off roller (16), is reknotted in the event of a yarn break by a knotter (3). For this purpose, the yarn running via the drawing-off roller (16) is picked up at the yarn-suction orifice (4b), held in a U-shape as the result of suction action in the storage pipe (4) and guided via guide pin (20) to the upper suction pipe (1), whilst the lower yarn end is guided via a further guide pin (21) into the other suction pipe (2), so that the two yarn ends can be connected in the knotter (3), the excess yarn being retained in the storage pipe (4). The device makes it possible, even at high spinning speeds, to bridge the unavoidable yarn breaks on open-end spinning machines without an operational interruption. Yarn entanglements as well a reduction of the yarn tension and the formation of loops and knotty threads are effectively prevented. <IMAGE>

Abstract: 1,144,943. Milling; stamping; making studs. DZUS FASTENER EUROPE Ltd. 11 July, 1967 [13 June, 1966], No. 26174/66. Headings B3A, B3B, B3K and B3Q. A machine for applying an identifying mark and a screwdriver slot to the head of a stud comprises a circular carrier 5 having a spaced series of stud holders 6 the carrier being rotatable stepwise to bring the studs successively to a press station 8 for stamping the mark on the head and then into engagement with a milling cutter 25 for cutting the slot before passing to means for ejecting the studs from the carrier. Studs are fed down an inclined feed tube 13 and released and inserted singly into the spring collet stud holders 6 by means of an inserter comprising inner and outer tube members 15, 14 and a pivoted pawl 22 reciprocated by a fluid pressure ram 18. The identification mark is applied by means of a reciprocable stamping die 23 operated by an air hydraulic intensifier 24. The milling cutter is mounted on a pivoted frame 30 and driven by a belt drive 28 from a motor 29 the frame 30 being rocked continuously by a pneumatic ram 32 between limit switches adapted to reverse the direction of stroke of the ram 32. A dashpot-type damper having a projecting rod 37 controls the speed of movement of the frame 30 and therefore of the feed of the milling cutter when the latter is actually cutting the slot in the stud. The studs are ejected from the holders 6 either by a blast of air at position 10 or failing that by a reciprocating claw 42. The shaft on which the carrier 5 is mounted is formed with twelve ratchet teeth adapted to be engaged by a spring-loaded pawl which is moved to rotate the carrier stepwise in dependence upon the vertical reciprocation of the stamping die. A spring-loaded latch engages spaced notches on the periphery of a flange of the carrier to index the carrier accurately. A safety switch operated by this latch prevents stamping, milling or insertion of a fresh stud except when the carrier is thus indexed.

Title: Agricultural machines having a tramp metal detector
IPC: A01D75/18
Filed: 1974-06-14
Abstract: 1452549 Forage harvesters SPERRY RAND CORP 14 June 1974 [25 June 1973] 26442/74 Heading A1F [Also in Division G1] In order to cancel out the effects of spurious magnetic field responses in a tramp metal detector of an agricultural machine a pick up coil is disposed substantially equally in first and second discrete regions of the crop input region and to which are applied first and second oppositely sensed equal strength unidirectional magnetic fields respectively. The invention is described in connection detecting ferrous objects in forage passing through a crop harvester of the type described in Specification 1343556 and the detector is mounted centrally of the harvester under the floor plate 30 between the feed rolls 21, 24 and cutters 18. The magnetic fields are produced by two elongate magnets 60, 61 Fig. 3 having U-shaped cross-section and polarised as shown, the magnets extending at right angles to the forage flow such that the flux lines extend through the base plate 30 into the region through which the forage passes. A multi-turn sensor coil 59 is wrapped continuously around the magnets and under normal operation no output is produced from terminals 43, 44 since the fields are disturbed equally by the machine parts. However if a ferrous object passes through the flux lines it disturbs one of the fields unequally with respect to the other and an A.C. output is obtained at 43, 44 which after amplification and filtering is rectified and then applied to a trigger pulse generator. The output of the pulse generator is then applied to a solenoid to energise an, alarm circuit or control circuit to stop the machine. Alternatively a manual switch may be provided which allows the operator to operate a clutch disposed between the harvester drive motor and shaft 18a to disengage the drive or to operate a brake Fig. 2 (not shown). The magnets may be separated Fig. 4 (not shown) in which case separate coils are provided which are connected in series. The coils 66, 67 need not lie in a continuous flat plane but may be arranged in a broad V-shaped configuration so that the detector can fit a V-shaped or U-shaped conveyor.

Filed: 1939-10-09
Abstract: 535,579. Ammunition projectiles. PATCHETT, G. W. Oct. 9, 1939, No. 27548. [Class 9 (i)]  Relates to percussion fuzes of the kind in which a striker is moved into alignment with an ignition cap by the action of a gyroscopic element rotated by frictional engagement with the projectile and serving to arm the fuze during flight. According to the invention, the gyroscopic element is so mounted in the projectile that in addition to the usual three degrees of freedom of movement it has a further movement in a direction along the axis of the projectile. In the form shown in Fig. 1, the gyroscopic element 16 carrying the striker 18 is assembled with its axis inclined, the lower end resting on a washer 19 having a central aperture leading to the percussion cap of the detonator 15. The element has concentric spherical surfaces 20, 21 engaging a spherical abutment face 23 on a hollow impact member 24 the forward movement of which is restrained by centrifugal spring members 29. On firing, the rotation of the projectile causes release of the members 29 and during acceleration the member 24 presses on the element 16 and imparts spin so that during deceleration, when the member 24 moves forward, this element can move to bring its axis into line with the axis of the projectile. On impact, the member 24 is forced inwards to move the striker into engagement with the percussion cap. In the modification shown in Fig. 2, the gyroscopic element is set with the striker pin 40 at right angles to the axis of the projectile and is retained by a washer 42 which sets back on discharge. The impact member 24 also moves rearwardly during acceleration to retain the gyroscopic element in frictional engagement with the washer. When deceleration occurs, the member 24 moves forwardly and the gyroscopic member precesses until the pin 40 is in line with the axial percussion cap. The gyroscopic member is in the form of two interfitting discs 39 enclosing a central gapped loading disc 43.
