Title: Improvements in telephone systems
IPC: H03G3/22
Filed: 1937-02-24
Abstract: 491,022. Anti - side - tone circuits. TELEPHONE MANUFACTURING CO., Ltd., FLINT, J. G., and RYALL, L. E. Feb. 24, 1937, No. 5578. [Class 40 (iv)] In a loud-speaker system employing amplifiers with automatic volume control, the latter is arranged to bring about a switching operation at the talking party's end should the speech currents reach a value likely to cause discomfort at the listening party's end. This effect may be due to reverberation at the talking party's end and is most noticeable on short lines. The speech currents are fed to the line 3, 4 through transformers T2, T3 and a part of the output is applied through a transformer T1 and amplifying valve V1 to a valve V2, which by virtue of a rectifier MC in its grid circuit supplies a direct current to rectifiers MA, MB associated with a third winding of the transformer T1 and increases its shunt effect. The loud-speaker is fed through the valve V1 and transformer T4. If the outgoing speech currents reach an unduly high value, sufficient current flows in the control circuit to operate a relay P, which locks and inserts an attenuation pad Z between the transformers T2, T3. The relay P is made marginal by a biassing winding in series with an adjustable resistance R1. The locking circuit includes a releasing key K and preferably also contacts of the key which connects up the telephone apparatus. Alternatively, the relay P may merely control a lamp or other indicator, and the attenuation pad may be inserted when the subscriber operates a key. The attenuation pad may be replaced by a filter which cuts out the lower frequencies.

Title: Improved process of and apparatus for splitting fluid hydrocarbons
IPC: C09C1/48
Filed: 1926-03-01
Abstract: 275,281. Longhi, C. March 1, 1926. Electrode furnaces.-An apparatus for decomposing liquid hydrocarbons by means of an arc, the latter by reason of the rotation of the electrode, is caused to elongate, and is then quenched, a second arc being struck at the point where the first arc was formed. The products particularly aimed at are acetylene and carbon black, but light and easily condensible hydrocarbons may also be produced. As shown in Fig. 1, the body of oil b is contained in a casing B, in the walls of which are mounted insulated electrodes i, while through the base of the casing passes a shaft m attached to a synchronous eightpole motor M, and carrying at its upper end a member r fitted with a number of electrodes e; as shown, there are sixteen moving electrodes, that is a number twice the number of the poles of the motor, the intermediate electrodes serving to short-circuit the arc struck from the preceding electrode, but it is possible to use other arrangements or even a plain rotating disc, in the latter case the arrangement preferably comprising a pair of discs placed edge to edge and driven in opposite directions. The oil being put in circulation by the rotating electrodes serves to draw out the arcs. In the modification shown in Figs. 3 and 4, there are employed two pairs of discs electrodes 2, 2<1>, one pair being mounted on insulated shafts and the other pair on a common shaft 8 which is earthed and mounted in eccentric bearings 4 so that the width of the gap may be adjusted; the pairs of electrodes are driven in opposite directions as by a crossed belt 6 running on insulated pulleys, and their direction of rotation is such that the electrodes are moving upwardly at the points at which the arc is struck. Gases collect in the upper part of the casing and are removed as by a pipe o, Fig. 1, a slight pressure being maintained in the casing to prevent the entry of air. The upper part B, Figs. 3 and 4, of the casing may be cooled, or the oil may be circulated through a cooler and a filter. Carbon black collects in the lower part of the casing, and is also carried away by the gases from which it is separated. Specification 248,830 is referred to.

Abstract: 426,092. Discharge lamps. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, JENKINS, H. G., and RYDE, J. W., c /o General Electric Co., Wembley, Middlesex. Feb. 23, 1934, No. 5997. Addition to 349,261. [Class 39 (i)] In a discharge lamp provided with means for introducing a continuous stream of impurity to vary the form, position or intensity of the discharge as described in the parent Specification, the said means consists of a solid so placed in the main body of the lamp that its vapour has substantially free access to the discharge space. Anthracene 6, Fig. 1, is distilled into a space in the lamp, bounded by a cylindrical iron electrode 2 and mica discs 8, 9, from a side tube 5 and a constriction 7 is then sealed. Leading-in wires 4 pass through the disc 8, and strips 11 of the electrode are bent to form supports for the disc 9 which is notched at its edges for the passage of the vapour. The temperature of the anthracene, during operation, may be adjusted by suitably positioning it within the lamps, e.g. in ripple tubes filled with neon, the constriction 7 is nearer the disc 9, and the disc 8 is replaced by an annular disc which is nearer the disc 9, and in ripple tubes filled with mercury and argon the disc 9 and the constriction 7 are near the pinch or the screen 9 may be abolished and the constrcition placed between the pinch and the disc 8. In another form, the material is located between the wall of the lamp and a tube which is provided with a constriction 16, is sealed to the wall at 14, and is shaped to provide an annular passage 15 for the vapour. The temperature of the material may be further adjusted by means of lagging on the tube. The filling may consist of neon at 10 to 40 mm. or of argon at 5 mm., and mercury. In a further form, the anthracene may be housed within an open glass container arranged loosely in the lamp and retained near an electrode by a constriction in the lamp.

Abstract: In a method and apparatus for the continuous annealing of metal strip the latter is passed through a series of fluidized beds maintained at progressively increasing temperatures; it may then be cooled either by passing it through the same series of beds in the reverse direction, by passing it through a further bed or beds maintained at a low temperature, or by passing it through a liquid bath.  The beds may be formed in a vessel by vertical partitions having slots through the strip may pass, or alternatively the strip may be caused by means of a roller system to pass in a vertical direction through each of the bed sections. In another embodiment the series of beds may be formed in a vertically arranged cylinder divided by diffuser plates. These various types of apparatus are illustrated. Where the strip is cooled in a liquid bath such as lead-bismuth alloy, the latter may be cooled by bringing it into heat-exchange relationship with the fluidized beds.
