Abstract: 1,223,849. Arc furnaces. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 30 Oct., 1968 [2 Nov., 1967], No. 49917/67. Heading H5H. To reduce the reactance of the supply conductors and balance the reactances of the phases, the electrodes 1, 2, 3 of a three phase arc furnace are supported vertically by respective electrode holders 29, 35, 21 and the two outer holders 29, 21 are connected electrically to a respective group of at least three vertically spaced conductors e.g. conductors 25, 26, 27 and 17, 18, 19, whilst the central holder 35 is connected to a group comprising at least one electrical conductor, e.g. conductors 32, 33, 34, the conductors of the two outer groups being parallel to the conductors of the central group. As shown, the central conductor 33 of the central group lies at the intersection of the diagonals joining conductors 17 and 27, and 19 and 25, and the other two conductors 32, 34 are mounted above and below it. In Fig. 3 (not shown), the three conductors of the central group are mounted in triangular formation about, the point of intersection and in Fig. 4 (not shown) the central conductors are more widely spaced than in Fig. 1. The inner group may comprises two vertically spaced central conductors (Fig. 5 and 6, not shown). Finally the central group may comprise a single conductor at the point of intersection. The invention is shown applied to the arrangement disclosed in Specification 975,651 (A.E.1). The outer group of conductors 25, 26, 27 is connected to a vertical conductor 31 secured to connecting member 16, the outer group of conductors 17, 18, 19 is connected to a vertical conductor 24 secured to a connecting member 14, and the inner group of conductors 32, 33, 34 is connected to a conductor 36 secured to connecting member 13. Flexible curtains of conductors 9 connect the connecting members 13, 14 and 16 to pairs of conductors 6, 7, 8, supplied from the phases of transformer 4.

Abstract: 1,057,849. Spray-producers. H. HEGE. Dec. 18, 1963 [Dec. 18, 1962], No. 49940/63. Heading B2F.  A rotary liquid atomizing apparatus comprises a rotatable body 6 having an integral flange 16 to which is connected through rodlike members 5 atomizing discs 1, 2. Each disc has atomizing edges 3, 4 and conically dished faces 13 and 14 on which the liquid thrown centrifugally from the body 6 collects as a film prior to leaving the associated edge 3 or 4 in droplet form. The liquid to be atomised is fed through the open-ended top of the body 6 at a particular rate-formulµ connecting this rate with the rotational speed of the body is to be found in the Specificiation- and half the liquid subsequently thrown upwardly along the inner wall of the body is conducted through four passageways 8 to be thrown into an inner groove 10 formed in the disc 1. From this groove the liquid overflows and passes, as a film to the atomizing edges 3 and 4 over the faces 14 and 13. The remaining half of the liquid moving upwardly along the inner wall of the body 6 passes from the body over a sharp edged body portion 15 from whence it is thrown into the groove 10 of the upper disc 2. As with the disc 1 the liquid then passes to the edges 3 and 4 over the faces 14 and 13. In the atomizer of Fig. 2 the liquid is thrown off in droplet form from six atomizing edges 24, 25 each of the discs 21, 22 and 23 receiving a third of the liquid fed downwardly into the rotating body 26. Perforated discs 36 are used to bisect the liquid thrown from the body to ensure that equal amounts are fed to the atomizing edges of each discs. In yet another embodiment wedge-shaped bodies 45, Figs. 3 and 4, are arranged between members 49 and 44 the latter being an integral part of the rotating body 42. In this embodiment the atomizing edges are vertical forming the outer edges 41 of the bodies 45. In the atomizer of Figs. 6 and 7 the liquid fed downwardly into the body 60 is thrown upwardly and outwardly against curved inclined faces 66 each of which forms the inner boundary of a wedge-like member 63. Slots 65 are formed between these latter members and the liquid being atomized passes through them along an associated member face 64 in film-form to vertical atomizing edges 68.

[Also in Division H3] In a method of reducing strains arising on ignition in a thyristor static converter including a plurality of series connected sections, each section comprising one or several main thyristors 1 connected in parallel and each section being shunted by an auxiliary thyristor circuit 2, 3, the ignition of the main thyristor(s) is delayed in relation to the ignition of the auxiliary thyristor 2 until the voltage across the main thyristor(s) has declined to such a value that the main thyristor(s) can ignite without damage and the auxiliary thyristor circuit 2, 3 is arranged so that after the ignition of the main thyristor or thyristors the current through the auxiliary thyristor is a fraction of that through the main thyristor. Also the extinction of the auxiliary thyristor 2 may be delayed in relation to the extinction of the main thyristor(s). A delaying arrangement may be connected between the control pulse channel 6 and control channel 5 so that control pulses are applied to the main thyristor 1 after control pulses have been supplied to ignite the auxiliary thyristor 2. The delaying arrangement may supply ignition pulses direct to the main thyristor. An arrangement may be provided which senses the voltage across the main thyristor and blocks the ignition of the main thyristor until the voltage across it has fallen to a safe value. The auxiliary thyristor 2 is protected by an impedance 3 which may be an inductance or resistance or both connected in series or parallel. The impedance 3 may alternatively be a variable inductance in the form of a saturable core inductor. Also the series impedance of the auxiliary thyristor itself may constitute the required series impedance 3 for limiting the current to a safe value. After turning on of the main thyristor the current through the auxiliary thyristor is a fraction of the current through the main thyristor. This may be obtained by choosing the auxiliary thyristor to have a higher conducting voltage drop than the main thyristor. The impedance 3 may delay extinction of the auxiliary thyristor 2 with respect to the extinction of the main thyristor so that the recovery time of the main thyristor is determined by the recovery time of the auxiliary thyristor. Voltage dividers 4 may be a resistor in series with a capacitor.

Abstract: 1448837 Control of printers COMPAGNIE HONEYWELL BULL 9 Nov 1973 [9 Nov 1972] 52246/73 Heading G4H A printer incorporates means for determining the amount of movement required between the current printing line and the next line on which data is to be printed. Printing takes place on a vertical succession of sheets separated by perforations. Data to be printed is divided into categories of information to each of which are assigned "stop levels" arranged in ascending numerical order which are the distances (measured as the number of inter-line spaces) between the top of a sheet and the various lines on which data of that category is to be printed. The required movement is determined by successively subtracting the distance from the top of the sheet of the printhead (number of inter-line spaces) from the stop-levels of the corresponding category until the first positive result is obtained. If the result is never positive, then to the result of the first subtraction is added the number of inter-line spaces corresponding to the height of the sheet, so that the print head can be aligned with the first relevant stop level on the succeeding sheet. Suitable apparatus is described for carrying out the above method
