Abstract: 1401161 Coating apparatus OWENS-CORNING FIBERGLAS CORP 13 April 1973 [14 April 1972] 17938/73 Heading B2L [Also in Divisions C7 and D1] Apparatus for coating fibres with a liquidstate material comprises a vessel for holding the liquid, said vessel having a side portion, means for supplying material to the vessel at a rate for maintaining the liquid at a desired level above the upper level of the side portion whereby, through surface tension, the liquid material defines a lip projecting from the said side portion for coating a fibre which passes through the lip, means for passing fibres therethrough, and wiper means for spreading liquid more evenly on a fibre which has passed through the lip. As shown glass from melting unit 11 is drawn as fibres 14 through nozzles 13 in electrically heated bushing 12, and is collected on rotating tube 18. Make-up wire 22, e.g. of Al, is fed down tube 26 by motor 24, the feed rate varying in response to signals from pneumatic probe 29 and control unit 28 so that a constant level 30 of molten metal, e.g. Al, is maintained in vessel 19, which is heated by heaters 27a in furnace 27. Said constant level 30 is such as to maintain a lip 39 of molten metal at the edge of vessel 19, and the fibre is drawn through the lip, thereby becoming coated, and passage over a heated rod 42 both improves spreading of the coating and reduces thermal shock to the wire. A size such as dilute stearic acid solution is applied by roller 20 from applicator 21.

Filed: 1971-06-02
Abstract: 1356296 Time switches CROUZET 2 June 1971 [8 June 1970] 18564/71 Heading H1N A programmer, for washing machines, for example, of the kind wherein a pawl for stepping a programme cam unit is driven by a first synchronous motor and the pawl is mechanically rendered operative or inoperative to control the stepping, has a second synchronous motor which is temporarily energized to control the pawl according to the selected programme. A normally-energized motor M drives a pinion 15 via reduction gearing and this drives internal teeth 14a of a continuously running impulsing cam 14d and an internal profile cam 14b having one or more recesses 146<SP>1</SP>. An eccentric pin 20d oscillates a pawl 20 having a nose 20e following cam 14b and nose 20a which engages teeth 4b of a programme cam unit 4 to step the latter each time nose 20e enters a recess 146<SP>1</SP>. A second motor P drives a pinion 30 via reduction gearing and an eccentric 31 thereon moves a lever 35 to hold pawl 20 in an inoperative position (as shown) or, when eccentric 31 is rotated 180 degrees, allows the noses 20a, 20e to function. The motor P is in series with contacts (K i , Figs. 1 and 3, not shown) actuated by the impulsing cam 14d and contacts (Ks) actuated by a selection cam 4s of the programme cam unit 4. Contacts Km operated by a cam 34 driven by motor P in synchronism with the pinion 30 are connected in . parallel with the series contacts (Ki, Ks). Thus, when the selection contacts (Ks) are closed, each closure of impulsing contact (Ki) starts the motor P, which then runs for one complete revolution of pinion 30 by means of the contacts Km. The selection contacts (Ks) thus determine whether programme cam unit 4 is stepped or not. This is convenient for prevention of stepping for prolonged intervals such as during heating, filling or the like, but for variation of normal stepping rate a plurality of recesses 14b<SP>1</SP> and corresponding plurality of impulses from each revolution of the impulsing cam 14d are provided (Figs. 2 and 4, not shown). Selection of the number of effective impulses by contacts (Ks<SP>1</SP>) controlled by another selection cam (4s<SP>1</SP>) determines the stepping interval. The pawl 20 may be normally inoperative, as shown in Fig. 5, or normally operative by arranging the rest position of eccentric 31 (determined by cam recess 34a) to be as shown or 180 degrees therefrom, respectively. The selection contacts (Ks, Ks<SP>1</SP>) are accordingly arranged to pass an impulse to motor P when stepping is not required (Figs. 1 and 2, not shown) or when stepping is required (Figs. 3 and 4, not shown).

Abstract: 659,830. Television. ELECTRIC & MUSI. CAL INDUSTRIES, Ltd. July 10, 1948, No. 18577. [Class 40 (iii)] Synchronizing signals for an interlaced television system are derived from a basic train of pulses of twice line frequency by selecting part of alternate pulses to form line synchronizing signals and a greater part or the whole of all the basic pulses to form frame synchronizing signals the selected parts of the pulses including the leading edges. The basic pulse train is derived from rectangular pulses 2 (Fig. 2), of negative polarity and of twice line frequency produced by means of a master oscillator 1 (Fig. 1), and applied to a valve 3 the anode circuit of which, since it includes short-circuited delay network 4, supplies a train of pulses, Fig. 2 (b) to a limiter 7 from which the basic pulse train (c) is derived. The latter pulse train is then divided by a factor 405 (for a 405 line system) in a pulse counting circuit 9 which supplies pulses such as 10 (Fig. 2), to an aperiodic multivibrator 12 to which is also fed pulses 8 from the limiter 7 via a differentiating circuit 21, 22 and limiting diode 18 and the circuit arrangement is such that pulses such as 24 (Fig. 2), are produced at the output of the multivibrator. These pulses, which are employed as frame keying pulses, are fed to a mixing valve 27 in which they are combined with line keying pulses also derived from the output of oscillator 1 via a tapping 29 on the delay network 4. This tapping is such that the pulses available thereat, Fig. 2 (g), have their leading and trailing edges occurring 1 Á/sec. later than and 1 Á/sec. earlier than the corresponding edges of the pulses of trains (b) (Fig. 2). The pulse train (g) (Fig. 2) is then fed to a pulse counting circuit 30 from which a pulse train (b) (Fig. 2), developed by incremental charging of condenser 34, controls a multivibrator 41 to supply pulses 46 (Fig. 2), which after amplification in amplifier 48 are applied to a further multivibrator 49 which supplies line keying pulses 54 (Fig. 2), to the mixing valve 27 from which the combined line and frame keying pulse train (l) (Fig. 2) is desired. The combined keying pulse train is then applied to a gating circuit 61 to which is also applied the pulse train output from the limiter 7, the latter pulses being gated by the keying pulses to produce the desired synchronizing signal train (m) (Fig. 2) comprising line pulses 65 and frame pulses 66.
