Title: Improvements in or relating to yarn winding
Inventor: POOL WILLIAM
IPC: B65H54/38
Filed: 1955-04-01
Abstract: 796,060. Winding yarns. BRITISH CELANESE, Ltd. March 28, 1956 [April 1, 1955], No. 9522/55. Class 120(2) Yarn fed to a rotating package support is traversed to-and-fro along the length of the support by a grooved or slotted traverse drum, the package being maintained in contact with and driven at the same surface speed as the traverse drum during part of the winding, but being maintained out of contact with the traverse drum when the ratio of the circumference of the drum to the circumference of the package is a ratio of two small integers such that "ribboning" is liable to occur, during which time the traverse drum is driven at a speed fluctuating in relation to the speed of the package to disturb ribbon winding. A package support 23 on a carrier 22 freely mounted on a spindle 17 that is held in jaws 18, 19 on a lever 16 is driven by a drum 12 driven at a constant speed. The yarn is traversed by a grooved drum 13 driven by infinitely variable gears so that the average surface speed of the drum 13 is approximately the same as that of the drum 12. A profile plate 41 at the end of the lever 16 is formed with rises 57 corresponding to package circumferences at which ribbon winding is liable to occur, which rises as the package grows pass over a fixed roller 42 and cause the lever 16 to force the package out of contact with the traverse drum 13, which is now driven at a fluctuating speed through a frictiomal connection with its shaft 7. When the package has increased slightly in size, the roller 42 engages a depression on the profile plate 41 and the lever 16 brings the package to its former position in which it drives the traverse drum 13 by surface contact. When the package is completed, it is swung out of contact with both drums 12, 13 by means of a pedal 52. As the pedal 52 is depressed, linkages 53, 54, 55 cause the levers 15, 16 to swing forward; a stop 56 on a rod 21 which operates the movable jaw 19 engages a bracket 43 and the jaws open to release the spindle 17. The movement of the lever 15 brings a brake pad 57 in contact with a brake drum 58 to stop the drum 13. A fresh spindle 17 and package support 23 are inserted between the jaws 18, 19 and yarn 24 is led between the traverse drum 13 and the package support 23 and temporarily collected on a waste roller between two adjacent driving rollers 12; the pedal 52 is then released, a spring 46 returning the levers 15, 16 to the position in which the package support 23 is in contact with both rollers 12, 13 and the brake 57, 58 is inoperative. Specification 792,832 is referred to.

Title: Improvements in or relating to Thermal-Converters

Abstract: 1,176,182. Measuring r.m.s. value. MARCONI INSTRUMENTS Ltd. Jan. 30, 1967 [March 4, 1966], No. 9580/66. Heading G1U. A thermal converter V has a number of thermocouple junctions J1, J2, J3 with seperate outputs T2, T3, T4, situated at different points along a conductor W1, which is heated at a particular region P by an electric heater H. Each junction reacts with a different predetermined time lag to heat from the heater. The conductor W1 may be platinum and the conductors W2, W3, W4, with which W1 forms the junctions, may be bismuth. Such converters are to be used in a feedback system for measuring the r. m. s. value of a fluctuating voltage or current. The thermocouple junctions of two thermal converters V are connected oppositely in series and the input applied to the heater of one of them (uppermost in the drawing). The resulting potential difference between the two junctions is amplified at 4 and fed back to the other heater as a steady D. C. The D.C. value at equilibrium, indicated by the meter 5, represents the required r. m.s. The particular junctions to be used are selected by the switch S1-S2 in accordance with the input frequency, such that the thermal time constants of the converters will be longer than the period of input signal, so that the feedback signal remains constant. The D.C. feedback may be smoothed if required by a capacitor C.

Title: Improvements in or relating to driving and control arrangements for agricultural tractors
IPC: B60K17/34
Filed: 1954-04-02
Abstract: 787,835. Tractors. ZAHNRADFABRIK FRIEDRICHSHAFEN AKT.-GES. April 2, 1954 [April 2, 1953], No. 9743/54. Classes 79(1). 79(2) and 79(5) [Also in Group XXIV] In an agricultural tractor having forward and reverse change-speed gearing the gear lever 39 is rotatable about a vertical axis and rockable in vertical planes to select the desired speed and direction of travel whereby the lever assumes corresponding positions for the same speeds in either direction of travel. As shown the tractor comprises an engine 76, a gear casing 1 and driven wheels 74, 75, the gear casing enclosing sliding gear change speed and reversing gearing (see Group XXIV), one of the wheels being permanently driven and the other wheel having a brake and being clutchable to the drive, the casing 1 carrying handles 52 which can be rotated horizontally through 180 degrees, and the tractor being provided with a power takeoff shaft 26 having a two-speed drive. The drive from an engine driven and Bowdencable-operated clutch is taken directly or through a layshaft to a main shaft 7 which is connectible through a sliding tooth geared reversing gear to an output shaft 20. The shaft 20 carries a bevel gear 23 meshing a crown wheel 24 carried by a shaft 53 to which one of the wheels is secured by a hub member 54. The hub 59 of the other wheel is freely rotatable on the shaft 53, a dog clutch 61 being provided. The hub 59 is provided with a brake 62, the brake 62 and clutch 61 being operated through Bowden cables 11, 12 from controls on the handles 52. The power take-off shaft 26 is coaxial with the shaft 20 and carries a gear cluster 27, 28 with which a gear cluster 30 splined to the shaft 7 can mesh, movement of the cluster being under the control of a hand lever 31. The handles 52 are provided with eyes 50, 51 which are adjustably clamped to a member 66 by a bolt 49 and nut 68, the interfaces between the member 66 and eyes 50, 51 being serrated. The bottom of the member 45 has a male conical portion 45 to engage a similar female portion 44 secured to the casing. A bolt 46 passes through the member 66 and the bolt 49 to engage the portion 44 and has a toothed head 47. The teeth of the head 47 are engaged by an arm of a bell crank lever 69 pivoted to a member 71 rotatably mounted on the bolt 46, rotation of the lever 69 tightening the portions 44, 45 and the lever 69 being controlled through a rod 73 terminating in a handle carried by the ends of the handles 52. A shaft 38 controlling the change speed and reversing gearing is splined to receive the gear lever 39, the lever 39 being thus adjustably plugged in on the shaft 38 to conform with the position of the handle means 52. Alternatively the gear lever can be firmly connected with two arms extending fore and aft, each arm being provided with a hand knob. The gear lever may alternatively be T-shaped, each end having a recess to receive a handle. Specification 787,836 is referred to.
