Abstract: 433,579. Converting. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Sept. 6, 1934, No. 25715. Convention date, Sept. 6, 1933. [Class 38 (ii)] [See also Group XL] A liquid-electrode discharge tube is provided with an ignition element, dipping continuously into the cathode, and with one or more auxiliary electrodes which are arranged in close proximity to the element and serve to produce the excitation of the main arc. The element may consist of boron or tungsten carbide and a potential drop of 100 volts per cm. must occur along the element in order that electrons may be released from the cathode. A holder 4, Fig. 1, supports an ignition rod 1 and a ring-shaped or cylindrical auxiliary electrode 3. The rod 1 may be completely surrounded by insulating material or may be housed within an insulating tube, and the electrode 3 may be insulated from the holder 4 by a sleeve. In another form, a carbide rod 11, Fig. 3, is provided with insulating rings 12 and metal rings 13 in connection therewith, and the auxiliary electrode consists of rings 15 electrically connected to, and supported by, the holder 16. In a mercury rectifier A, Fig. 5, the auxiliary electrode H is connected through a valve V and resistance R to the anode A. Alternating-current, the phase of which may be displaced with regard to the main current supply, is fed to the primary of a saturated transformer T. A peak potential, generated in the secondary winding, is superposed on the potential, from a battery B, on the grid of a thermionic valve E, to close the circuit of the said valve and to create a high potential difference between the ends of a resistance W, and thus between the ignition element Z and the cathode K. The valve E may be replaced by a gas- or vapour-discharge tube. The transformer T, Fig. 6, may be provided with a primary connected to the mains, and with a primary which is energized by continuous-current, the magnitude of which can be adjusted by the variable resistance Rr to vary the degree of saturation of the transformer and thus to displace the peak potential. In other forms, the battery B may be replaced by a source of alternating-current together with a rectifier, or the valve E may be replaced by a rotating contact or a tilting relay, or may be dispensed with so that the transformer T is connected directly to the ignition electrode, or the valve V may be connected to the supply mains through a transformer, or may be eliminated so that the auxiliary anode is connected directly to the anode of the rectifier.

Abstract: 720,102. Magnetic reproducing apparatus. LYONS & CO., Ltd., J., and COSSEY, R. J. H. Feb. 6, 1953 [Nov. 6, 1951]. No. 25956/51. Class 40 (2). In a magnetic reproducer in which a tape is drawn from one spool on to another by a capstan, an automatic control for the motors is arranged to cause any desired part of the tape to be repeatedly reproduced and rewound. In the embodiment described a control member is employed consisting of a feeler which is pressed against the outer turn of the tape on take-up spool 15 and is pivoted about an axle 31 carrying an electrical contact arm 32 which may be brought into contact alternately with an adjustable stop contact 34 and a similarly adjustable " start contact 35. The contacts 34, 35 are carried by slides 36, 37 which are set by control knobs 38. 39 in relation to indicator plates 44, 45 in accordance with the part of the record tape on the spool 15 it is required to reproduce. The operation may be understood by reference to Fig. 3 in which a power unit 50 is shown which is connected to a mains supply and delivers alternating current for driving take-up motor 25, reversible capstan motor 23 and rewind motor 24, and direct current for relays A/1, B/3 and C/3. Switches s 2  and s 3  are coupled to a main switch s 1 , all of which are shown in the OFF position. When s 1  and s 3  are closed, relays A/1 and C/3 become energized. The energizing of relay C/3 operates contacts c, to open-circuit the rewind motor 24 and connect take-up motor 25, and operates contacts c 1 , c 2  to drive the capstan motor 23 in forward direction. The energizing of relay A/1 operates the contacts a, to connect power to any of the motors 23, 24, 25. As tape is wound on to spool 15, a point is reached when contact arm 32 connects with contact 34, and energizes winding 57 of relay B/3 to close a holding circuit therefore through contacts B1 and to operate contacts B3 to de-energize relay C/3 to cause the change-over of contacts c 1 , c 2 , c 3  whereby the capstan motor 23 is reversed in direction, the takeup motor switched off, and the rewind motor 24 switched on. At the same time muting contacts B2 on the amplifier 55 are closed. Rewinding then proceeds until the arm 32 connects with contact 35, as a result of which the relay B/3 is shortcircuited and thereby released, and the relay C/3 re-energized to restore normal forward operation and reproduction.

As shown in Fig. 1, the rollers 3 are mounted upon axles 4 hinged upon brackets 5 on the support 1, and the material is fed by a shoot 6 over an upraised central portion 7 of the table, which is carried by a vertical shaft 2a driven by bevelgearing 7, 8 from the driving-shaft 9. The crushed material passes through annular apertures 1<a> in the support 1 into a funnel or casing 14 terminating in a discharge mouth 14<a>. The shaft 2a is supported in a step bearing 10<a> at the lower end of a housing 10 suspended from the support 1. An air current is caused to pass upwards through the crushed material escaping from the edge of the table to carry the fine particles up through the enclosing casing 12 into a conduit 13 leading to a storage bin. The air passes through apertures 10<c>, 1<c> in the housing 10 and support 1 respectively, and is deflected by plates 15, 16. Removable fan-blades 1<x> may be secured to the lower side of the table. The table 2 and rollers 3 are provided with detachable wear plates or sectors 2<x>, 3<x>. Each roller may consist of a number of sections mounted side by side on a shaft and rotating independently thereon, and the sections of some of the rollers may be of different lengths to the sections of adjacent rollers so that the tracks of the sections of some of the rollers lap over the tracks of the sections of other rollers. For regulating the velocity of the air current through the casing 12 and thereby controlling the fineness of the material carried out by the air current, an adjustable discharge sleeve 20, Fig. 7, comprising two telescoping members is mounted in the discharge conduit 13. The members 20 are raised or lowered by means of a shaft 21 and cable 22, and the lower member is provided at the lower end with a flaring or funnel mouthpiece 30<a>.
