Abstract: 494,104. Draw - off mechanism for circular knitting - machines. CLARKE, A. V. April 20, 1937, No. 11282. [Class 74 (ii)] Draw-off mechanism, for use particularly in circular knitting-machines, comprises fabricengaging rollers 11a, a circular track 24 and a wheel 23 which rolls around the track and drives the rollers via gearing 18-22. When the rollers climb the fabric the wheel is lifted slightly from the track and slip occurs between the wheel and the track. The rollers and wheel are journalled in a frame 10 resiliently supported on springs 30 which rest on an annular plate 26 rotated in unison with the needle cylinder (not shown) of a rotating-cylinder knitting-machine from a shaft 34. Sleeves 33 enclose the springs. The arrangement is such that during normal rotational knitting the take-up speed is slightly greater than the speed at which fabric is produced, so that periodically the rollers 11a climb the fabric (the sleeves 29 sliding up the pins 28). The pressure of the wheel on the track may be varied by screwing the sleeve 29 up or down, e.g. down to take the weight of the rollers &c. off the track. As applied to a stationary cylinder machine, the track 24 is rotated and the frame 10 stationary. The driving connection 35a, 35b, which does not transmit drive to the fabric take-up mechanism during oscillatory knitting, is the subjectmatter of Specification 494,014.

Title: Improvements in or relating to escapement mechanism
IPC: G04C5/00
Filed: 1939-04-18
Abstract: 596,216. Escapement mechanism. CLIFFORD, C. F. April 18, 1939, No. 11682. [Class 80(iv)] [Also in Group XVIII] A magnetic escapement comprises complementary relatively oscillating and rotating members on one of which there is at least one polar formation and on the other of which there is provided a wavy magnetic path and in which either or both of the twc members is or are permanently magnetised whereby torque applied to the rotary mem ber impulses the relative oscillatory movement and produces escapement by causing the polar formation to follow the said wavy path while magnetically locked thereto. A pendulum a, Fig. 1, suspended on a knifeedge fulcrum b carries a hollow non- magnetic block c within which is fixed a magnetic conductor d of substantially sine wave form and having eight complete waves. An eight-pole star magnet e is rotatably mounted within the conductor d each alternate N. and S. poles of the magnet being adjacent corresponding points on each wave of the conductor d. The star magnet e is driven by suitable means but will only rotate when the pendulum a oscillates because of the magnetic lock between the poles of the magnet e and the conductor d. The star magnet e will rotate at a speed corresponding to the natural frequency of oscillation of the pendulum a since the poles of the magnet e follow the conductor d so stimulating oscillation of the pendulum a. In another embodiment, Fig. 2, the star magnet is replaced by a bar magnet h which co-operates with a stationary conductor f. In this case the-bar magnet h rotates and oscillates. In further embodiments, not shown, the pendulum carries two poles which co-operate with a rotating member having a magnetic conductor of wave form. In a further embodiment, Fig. 6, the device comprises a pair of permanent magnets n secured by opposite poles to a magnetically conductive base and to each free pole is attached a reed n<SP>1</SP>. The reeds n<SP>1</SP> which have flux induced in them by the magnets n cooperate with a wavy magnetic conductor o which thereby rotates at a speed controlled by the natural frequency of vibration of the reeds. In other embodiments, not shown, the polar formation rotates within an oscillating wavy magnetic conductor. The wavy conductor path may be formed as shown in Fig. 11.

Abstract: 970, 234. Magnetic recording &c. heads. FUNKWERK LEIPZIG VEB. March 25, 1963, No. 11700/63. Heading G5R. A magnetic head for recording, playback, or erasing signals on a magnetic carrier, comprises a core which is wound from a strip-like soft magnetic material of low remanence. Fig. 4 shows a front view and a top view of a magnetic head arranged so that its plane extends parallel to the surface of a magnetic record which is locally flat. The core 2 may be produced by winding the strip into an annular roll, possibly glueing the individual convolutions together, and cutting the roll into two halves diametrically. After the ends of the core halves are lapped, the windings 3 are mounted and the halves mounted together with the interposition of gap establishing foils between one or both pairs of the lapped ends. A recess 7 may be provided to give the required depth of core gap, and a running path 6 may be provided for the magnetic carrier 1, which is preferably disposed parallel to the plane of the core 2. The head is preferably embedded in synthetic plastic material such as a polycarbonate material. Two heads embedded in a common mass of plastic may be arranged on opposite edges of a tape for two-track working, Fig. 6. In this case the entire track spacing and the entire depth of the magnetic head can be used for intertrack screening purposes. If a composite head for more than two tracks is required, a plurality of magnetic heads, each having a core as shown in Fig. 4, may be arranged concentrically one within the other, all of their working gaps being in line with each other. The different sizes of cores can be compensated for by suitably choosing the thicknesses of the strips from which the cores are wound or by varying the breadths of the back gaps. It is also possible to give the individual cores equal magnetic lengths by suitably shaping them, e.g. giving the strip a curved or wavy shape.

[Also in Division B8] In a machine for forming and opening bags made of plastics film, a pair of forming bars 15, 15<SP>1</SP>, mounted on arms 11, 11<SP>1</SP>, rotatable on a shaft 12, are positioned to enter between the layers of a double layer of plastics film 20 fed from a supply roll 21. A sealing and cutting means 22 operates in conjunction with the rotation of the forming bars to cut and seal the plastics film after the passage of the forming bars in the plastics film past the sealing and cutting means. The forming bars, which comprise jaws 16, enter between the layers of plastics film 20 at station A, and then pass through the synchronously opened cutting and sealing jaws 22, carrying a length of plastics film 20 with them. The jaws 22 then clamp shut behind the forming bars, and seal the two layers of film together, completing a bag round the forming bars. At station C the jaws 16 start to open under the influence of a fixed cam on shaft 12 and outwardly distend the bag until the fully open position is reached at station D, when the bag is ready for product insertion. Alternatively the bag may be removed from the forming bars at this juncture. The jaws 16 then close up again ready for the next bag cycle. As shown, the forming bars may be disposed at an obtuse angle to the arms 11, 11<SP>1</SP>, to facilitate entry between the layers of plastics film 20. Alternatively the forming bars may be perpendicular to the arms and a cam-operated picker 18 (Figs. 1, 2, not shown) employed to draw back the edge of one layer of the plastics film to provide an entry point. The arms are driven intermittently by a Geneva drive.
