Title: Improvements in or relating to yarn or like winding machines
IPC: B65H54/14
Filed: 1940-06-11
Abstract: 541,819. Winding yarns &c. UNIVERSAL WINDING CO. June 11, 1940, No. 10181. Convention date, June 12, 1939. [Class 120 (ii)] In a yarn or like winding machine in which the yarn is wound on a rotating package by a longitudinally extending strand-engaging member having a helical formation on its periphery for engaging the yarn with relative reciprocation between the member and the package, the member is rotatable about its longitudinal axis and means are provided for turning it about such axis to advance the yarn and the traverse stroke progressively along the length of the package. As shown the traverse rod 48 is reciprocated longitudinally of the cop tube b and package B from a cam-actuated rod 25 and annular arm 46, so that the rod 48 is offset from the rod 25; a screw thread 50 is formed on the rod 48 to engage the yarn y and lead it to the package B and the rod is intermittently rotated to feed the yarn along the package by a ratchet wheel 53 on a bushing splined on the rod and actuated by a pawl 60 pivoted in the end of an arm 61 pivoted on a pin 62 in bearings projecting from a fixed member 40. The arm 61 carries a roller 75 which at each traverse of the rod 40 engages a cam member 71 adjustably fixed to the arm 46, and the arm 61 being thereby rocked on its,pin 62 and moving the pawl 60 to rotate the ratchet 53 and rod 48; adjustment of the cam member 71 determines the amount the ratchet and traverse rod are rotated at each traverse. A spring 64 maintains the pawl in engagement with the teeth of the ratchet wheel, a spring 67 coiled about the pin 62 tends to move the pawl rearwards on the teeth of the ratchet wheel,a stop finger 68 limits such rearwards movement and a detent pawl 69 prevents backward movement of the ratchet wheel. The package B formed has a taper corresponding to that of the cop tube b but by giving the screw thread or other helical formation on 'the traverse rod a varying pitch the rate of feed of the yarn along the rod may be regulated to build a cop having a cylindrical instead of a tapered shape. In a modification the traverse rod is in alignment with the reciprocated rod 25 and is coupled to it by a connection allowing it to be rotated independently of the rod 25. The ratchet wheel is formed on or attached to a sleeve which is slidably keyed to the outer end of the traverse rod and has an annular slot engaging a pin projecting from the bearing for the outer end of the rod and the pawl engaging the ratchet wheel is carried by a rockable lever mounted in the bearing and having an angularly disposed toe piece which is engaged by a cone cam adjustably secured to the outer end of the traverse rod. In a further form the traverse rod is connected to the rod 25 by a one way ball or roller clutch which is rotated at each traverse to feed the yarn along the traverse rod by a stud or an arm projecting from the machine frame and engaging a cam groove in the periphery of a sleeve of the clutch.

Title: Improvements in the operation of dynamo-electric machines in mutual synchronism
Inventor: CHOUDHURY SHAFI-UDDIN AHMED
Filed: 1955-04-07
Abstract: 817,388. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO. Ltd. March 7, 1956 [April 7, 195S], No. 10317/55. Class 38 (3). Dynamo-electric machines A and B are operated in mutual synchronism by having their polyphase secondary windings 3, 31, interconnected and their primary windings 1, 11 connected to a single-phase source 2. A half wave rectifier 5, shunted by a capacitor 4, is included in the primary circuits of the machines whereby the windings 1, 11 are energized by an A.C. component passing through the capacitor and a D.C..component resulting from the provision of the rectifier. Machine A acts as a transmitter and machine B as a receiver, any misalignment of the rotors introducing a torque proportional to the angular difference and in a. sense to correct such difference, the torque due to the D.C. component being additional to that provided by the circulating currents in the secondary windings. The primary windings of the machines may be of the star-connected type with two of the phases short-circuited at their ends, the short-circuit connection and the terminal of the remaining phase winding being joined to the single-phase supply. In another arrangement, each of the machines have two primary windings in quadrature, with a phasesplitting capacitor in series with one of the windings, Fig. 2 (not shown). The D.C. component is, in this case, confined to those primary - windings which are connected directly to the single-phase source. In a further modification, the primary windings are wound for three phases with the single-phase current supplied to the terminals of two of the phase windings, and the third phase winding being supplied through a phase-splitting capacitor, Fig. 3 (not shown). When the machine A is rotating, the machine B Will accelerate from standstill into synchronism with the transmitter, and the D.C. component will provide damping to minimize hunting. Specification 764,899 is referred to.

The apparatus comprises a vertical retort 10, Figs. 1 and 2, into which the briquettes are fed through a tube 41 having a branch 42 through which gases evolved from the briquettes during their descent to the retort may be withdrawn. Surrounding the feed tube is a condenser 11 connected to the top of the retort by a liquid - sealed expansible coupling 28. A grid 44 prevents solid material being carried into the condenser with the gases and vapours from the retort. A tube 9 leading from the condenser is connected to a vacuum pump. A division 37 divides the condenser into two zones A. B, in the lower of which, A, magnesium vapour is condensed and drawn off through a pipe 36 while in the upper zone B any accompanying metal, such as sodium, may be separately condensed and drawn off through a pipe 38. Heating units 59, 61 surround the zones. Where a relatively high condensing rate is being maintained, cooling coils surrounding the zones may be employed. The feed tube is in heat-conducting relationship with the condenser, the heat absorbed from the condenser serving to preheat and dry the briquettes on their way to the retort. The retort charge is heated by a central core 47 provided with heating elements 54 and a surrounding heating element 58. The walls of the retort and core are provided with grooves 62, 63, Fig. 3, to facilitate escape of gases and vapours. Small quantities of hydrogen or similar gas is introduced through holes 23 to aid the upward passage of evolved vapours. The feeding of the briquettes to, and the withdrawal of spent residues from, the retort are effected at regular synchronized intervals, without interfering with the maintenance of the desired partial vacuum, by an auxiliary charging unit 71 and discharging unit 72, having pairs of valves 1 and 2, 3 and 4 respectively which are interconnected so as to operate in the desired sequence. The valves have piston-like extensions 87, 88 to avoid crushing the briquettes.
