Abstract: 676,722. Production of thread from glass or other thermo-plastic material. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY & CIREY. March 10, 1950 [March 10, 1949], No. 6079/50. Classes 120(i), 120(ii) and 120(iii) A process for the production of threads formed from discontinuous fibres of glass or deposited on a receiving member in the form of a thin veil which leaves the member as a sliver, which is subjected to a drafting action to transform it into a roving, which is spun into thread, which is then wound on a bobbin, which process consists in carrying out the operations of drafting and spinning by independent means and utilising for the spinning operation a spinning pot, of which the peripheral speed is greater than the speed of the roving as it leaves the drafting device, this difference of speed assuring twisting of the roving and the said twist having a value which is a function of the difference in speeds. As shown molten glass in a crucible 3 flows from the orifices of spinerettes 2 in fine streams and is deposited into a funnel 5 the wall of which is formed by unconnected elements 6. The discontinuous fibres so formed are in the form of a thin veil on the wall of the funnel, which veil leaves the funnel at 9 in the form of a sliver which is subjected to a drawing force exercised by the ejector 10 in communication, through a tube 11, with a source of gaseous fluid under pressure. The drawing action parallelizes the fibres, the resulting roving leaves the tube, 15 and passes into the spinning pot 13 where it is spun on the internal wall of the pot to form a thread package, the traverse necessary for the formation of this package being obtained by vertical reciprocation of the ejector. More than one spinning pot may be provided and arrangements made to feed in to them successively so that whilst one is being filled the thread in the other or others is withdrawn and re-wound on to a bobbin.

Title: Timing circuit
IPC: H03K17/28
Filed: 1976-02-17
Abstract: 1529103 Transistor switching circuits GENERAL SIGNAL CORP 17 Feb 1976 [21 Feb 1975] 06224/76 Heading H3T An electrical timing circuit, for providing a relatively long delay without the need for an unduly large capacitance, comprises a charge storage means 26, a discharge path via 30, 32, 40, 42, 44 for discharging the storage means, a timing means 54 operative in response to charge on 26 to permit the said discharging repetitively for discrete periods spaced by longer intervals, and means for providing an indication, via 66, when 26 is discharged to a predetermined level. In an embodiment, used on a train to delay automatic application of the brakes, the circuit 12 operates continuously as long as a switch 110 is closed, capacitor 26 being maintained charged. If 110 is opened operation of the circuit 12 continues until the charge remaining on 26 is insufficient. Circuit 12 has one time constant provided by the charging of a relatively small capacitor 40 through an FET 30, and another time constant provided by a resistor 58 and a capacitor 60 in connection with an integrated timing circuit 54 functioning as a one-shot multivibrator. When the charge on capacitor 40 reaches a value sufficient to trigger a unijunction transistor 34 a trigger pulse is passed to input 2 of circuit 54. The resulting output from terminal 3 of 54 is a low potential which turns off FET 30 and is maintained for the time determined by 58, 60, typically 1 ms. The output from terminal 3 is also used to actuate a control device, passing first to a flip-flop (68), Fig. 1B (not shown), which acts to produce a square wave output of frequency 500 Hz. This output passes to a single-ended pushpull amplifier stage (96), Fig. 2 (not shown), feeding a series resonant circuit (98) tuned to 500 Hz. The output is rectified and supplied to the solenoid (106) of a relay which holds off the automatic brakes until the 500 Hz supply is interrupted by discharge of capacitor 26.
