Title: Apparatus for manufacturing glass strands
IPC: B65H59/38
Filed: 1962-07-19
Abstract: <PICT:0973445/C1/1> An apparatus for manufacturing glass threads, in which molten glass is formed into one or more streams from which the threads are drawn out by winding them on to a rotating spool, the speed of rotation of the spool being controllable to influence the thread diameter, has an over-dimensioned asynchronous motor to drive the spool head, the velocity of which may be varied by varying the voltage at the terminals of the motor by interposing a pre-magnetized choke, the pre-magnetized choke being regulated by a controlled standard voltage and in addition by a correcting voltage which depends on the difference between the actual and the standard speeds of rotation of the spool head or of the drive motor. Streams of molten glass are drawn out through a nozzle 1 into elementary threads 2 and pass through a collecting device 3 to form a spun thread 4 which passes over a thread guide 5 and is wound on a spool 6. The spool 6 is mounted in a bearing 7 and is driven via a belt and pulleys 9 and 11 by an asynchronous motor 10. A suitably shaped cam driven by a synchronous motor actuates the moving arm of a potentiometer and the varying voltage tapped off is used to vary the speed of the motor 10 to compensate for the increasing diameter of the spool as the thread is wound on to maintain a constant speed of drawing.  An aluminium disc 12 carries permanent magnets in a number of apertures near its periphery and its rotation, at the same speed as the spool head 6, produces impulses in a generator 13 which are amplified and rectified and the resultant D.C. voltage compared with the standard produced by the cam-operated potentiometer.  Any difference, caused by a difference in the standard and actual values of the speed of rotation of the spool head 6, is used to further alter the speed of the motor 10 to compensate.  The speed of the motor 10 may also be varied in response to changes in the viscosity of the melt as determined by its temperature. A suitable circuit is disclosed.

Abstract: 464,405. Vehicles with momentummotors. FOTTINGER, H. Oct. 14, 1935, No. 28368. Convention date, Oct. 13, 1934. [Classes 79 (i) and 79 (iii)] In a vehicle provided with an energystoring flywheel for increasing the tractive force at starting &c. and for braking purposes, such as is described in Specification 432,670, [Group XXVI], means are provided for increasing the load on the driving axle when the flywheel is connected to it in order to prevent slip of the driving-wheels due to the increased forces. Fig. 1 shows part of a railcar comprising a bogie 1 carrying a motor 2 coupled by an articulated shaft 5 to the axle of the driving-wheels 7, and also the energystoring flywheel 4 which is coupled to the driving axle for increasing the tractive effort or for braking purposes. The vehicle body is in part supported on the bogie 1, being normally carried on it by a pivotal member 10. When the flywheel is coupled to the driving axle a lifting device 8, such as an hydraulic or air-pressure cylinder, arranged between the bogie and the body, is operated so as to take the load due to the body from the member 10 and transfer it to the region of the driving axle, the additional load thus carried by the driving wheels preventing slip arising from the increased tractive effort. Fig. 2 shows an arrangement in which the lifting device is hydraulically operated by pressure fluid supplied from a pump 14 also supplying the hydraulic coupling 12 by which the flywheel 13 is connected and disconnected, and in which a single multi-way cock 15 controls the supply of fluid both to the coupling and the lifting device so that the latter is always in operation when the flywheel is coupled by the clutch. A safety device, such as an abutment brought into position by compressed air, hydraulic pressure, or electrically, may be provided to prevent jumping of the axle or axles which are relieved of pressure. The lifting device may be operated by the same source, for example of steam, electricity, or compressed air, as the driving motor, and it may consist of a lever or screw-and-nut mechanism.
