Title: Improvements in methods of and apparatus for producing long glass thread or yarn
IPC: C03B37/028
Filed: 1924-05-03
Abstract: 233,136. Haddan, R., (Corning Glass Works). May 3, 1924. Forming glass threads.-A method of producing long glass thread or yarn consists in drawing a number of strands of molten glass and winding the drawn strands on a drum in a helical winding, the adjacent turns of which are separated from one another. Apparatus for carrying out the process, shown in sectional elevation in Fig. 1 and in plan in Fig. 2, comprises a support 20 for holding a number of glass canes 22 and for feeding them forwards to gas burners 24, and a winding mechanism consisting of a drum 23. A drop of molten glass from each of the canes is thrown on to the drum, and the threads thus formed are wound in a series of non-adhering turns or layers, the pitch of the turns in the layers being the same but is reversed in adjacent layers. The glass canes 22 are carried by supports 32, 33, the latter being moved slowly by a screwed spindle 34, driven by suitable gearing, to feed the canes to the burners 24. Both the holders and the burners can be tilted about an axis parallel with the spindle 34 in order that the glass threads x may be wound on to the drum in the same plane and will wind up as a yarn instead of as individual threads. The drum on which the threads are wound consists of a removable cylinder 101 attached to a spider 100 which is keyed on a vertical driving-shaft 108. The spider is moved along the shaft 108 by means of a screwed spindle 112 the rotation of which is reversed when the drum reaches the limits of its travel. The drum thus reciprocates along the shaft 108 and the threads x are wound on its surface in a helix. When filled, the drum may be transferred to other mechanism for unwinding the threads. Means are provided for varying the speed of rotation of the drum according to the thickness of the thread it is desired to produce. Instead of using canes, the glass for the threads may be supplied. by molten metal issuing from orifices in a tank under the action of gravity. In this case, the drum is preferably arranged directly under the orifices with its axis horizontal.

Compounds containing 6-10 per cent. of fixed sulphur are preferred.  In compounding the synthetic rubber, the amount of the compound to be added is calculated on the amount of sulphur required to vulcanize the hydrocarbon, about 3-6 per cent., in addition to that required by the rubber.  The product is particularly useful in the vulcanization of co-polymers of butadiene, e.g., with styrene or acrylonitrile. According to an example, 100 parts of Hycar OR, 0.5 parts of stearic acid, 25 parts of a compound of acid sludge extract boiling at 250-280 DEG C. at 12 mm. mercury, containing 10 per cent. of fixed sulphur, 1.5 parts of accelerator, 50 parts of Channel black, and 5 parts of zinc oxide are vulcanized to a soft product at 45 lbs. steam pressure for 30 minutes.

Abstract: 626,284. Variable condensers. DODDS, J. M., LUDLOW, J. H., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. July 10, 1940, No. 11489. [Class 37] [Also in Groups XL (a) and XL (c)]  The resonant tuning circuit of a high-power short-wave transmitter comprises a variable gap type condenser having a fixed plate P1 attached to or forming part of the anode A1 of a valve and co-operating with an adjustable plate M1 hingedly supported by a plate F1 on a fixed electrode, e.g. the screening box S. The plates of the condenser are in parallel planes which are parallel also with the axis X of the inductance loop formed by the screen S, the electrode supports within the insulators B1, B2 and a member C which may be in the form of a strap connection C or a helical coil. As shown, the strap C connects the anodes of two push-pull valves, the second valve A2 being associated with a condenser P2, M2. The hinges supporting the movable condenser plates are short-circuited by corrugated copper strips soldered to the plates on each side of each hinge. Instead of two valves arranged in push-pull, a single valve and a symmetrically arranged fixed condenser may be employed as described in Specification 476,188, [Group XL]. The variable condenser arrangement also is applicable to a resonant circuit which excludes a valve but uses an evacuated condenser of fixed capacity. The arrangement of variable condensers described makes provision for bringing into exact resonance the tuned circuit the major portion of the capacity of which is constituted by the electrostatic capacity between the valve electrodes. Specification 414,753, [Group XL], also is referred to.
