Title: Method of introducing a jet of molten metal from a casting ladle centrally into the mould of a continuous casting installation
IPC: B22D11/10
Filed: 1961-07-05
Abstract: 936,259. Continuous casting-machines. CONCAST A.G. July 5, 1961 [Aug. 2, 1960], No. 24243/61. Class 83 (1). The pouring jet is guided into a continuous-casting mould by electromagnetic means. A D.C. voltage is applied to the pouring jet 8 by electrodes 2 and 12 in the ladle and mould respectively, and the pouring jet flows between the poles 7a of an electromagnet 7 mounted on a turntable 6. The jet is therefore caused to move laterally to an extent depending on the magnitude of the voltage applied to the electrodes 2, 12, and of the magnetic field between the poles 7a so that it can be moved to the centre of the mould 5a from any non- central position. In a modification there are two magnetic deflection systems placed one above the other and offset relatively to one another by 90 degrees.

[Class 4] A helicopter, Figs. 1 and 2, has a main lifting rotor 1 and a control rotor 2, having a diameter between 0.4 and 0.7 of that of the rotor 1, mounted on substantially vertical axes in supports 3 and 4. The rotors 1 and 2 have flapping blades and rotate in opposite directions and their supports 3 and 4 are inclined laterally, as in Fig. 2, to a degree necessary to balance torque reaction. The rotor hubs may also be tilted about fore and aft axes in the ends of supports 3 and 4 in order to provide variable inclination for control in roll and yaw. The rotors may be driven by the same or independent engines and may auto-rotate for gliding flight.

Title: Improvements in or relating to electric arc lamps
IPC: H05B31/00
Filed: 1920-08-26
Abstract: 150,354. Thompson, H. H. March 26, 1918, [Convention date]. Arc lamps.-In a heavy-current search-light or other lamp, rotating and feeding devices for an electrode are arranged so that the rate of feed is varied by altering the speed ratio of parts appertaining to these devices. In one arrangement, the electrode is gripped by rollers 12, Fig. 1, in spring-urged brackets pivoted to a sleeve 8, rotating in a stationary head 1. A shaft 11 drives the sleeve through bevel-gear 10, 9. The rollers 12 may have pairs of sharp edges engaging the electrode. Other spring - urged brackets on the sleeve 8 carry the feed-rollers 16, which may be uniform or may be serrated over a small part of their periphery, the feed then being intermittent. The feed rollers 16 are geared to each other and to a shaft bearing a bevel-pinion 23. A bevel-wheel 24, gearing with this pinion, rotates freely on the sleeve 8 and is driven by a second shaft 26. This is driven from the first shaft through a three-speed device, each section of which comprises a driving-wheel 32-34, an idler, and a toothed wheel forming with a coil 43, 45, or 46 and a friction disk 41, fast on the shaft 26, an electro-magnetic clutch. Shaft 11 is driven at constant speed by a motor 30. Normally, the middle clutch 45 is closed by a spring, the ring 24 is driven at the same rate as sleeve 8, and there is no rotation of the rollers 16 on their axes. If the end of the electrode is out of focus, a beam of light from the arc, concentrated by a reflector, falls on a thermal switch 48 or 49, which opens the middle clutch 45 and closes one of the others, so that the sleeve 8 and ring 24 rotate at different speeds, and the electrode is fed or retracted. At starting, or if the electrode is broken, a hand switch 60 may be closed so as to open the middle clutch 45 without closing the others: this causes a rapid feed of the electrode. When the electrodes meet, the switch 60, unless still held by hand, is opened by a coil 80, and normal operation is resumed. Alternatively, the shaft 26 may be rotated uniformly and the shaft 11 at a varying speed, for instance by a shunt or compound-wound motor in series with the arc and with a rheostat. The Specification as open to inspection under Sect. 91 (3) (a) also describes an arrangement in which the shafts of the feed rollers are carried by the stationary head. In this case, one of the idlers driving the electro-magnetic clutches is omitted so that this clutch gives a reverse motion. Control may be effected by a shunt solenoid which can close the circuit of either of two clutches for slow feed or withdrawal of the electrode, all the clutches being open when the arc is normal. The hand switch is in this case arranged to open both of these clutches and to close a third giving rapid feed. To allow rotation of the electrode, each feed roller may carry a number of disks engaging the electrode and rotating about axes at right angles to that of the roller. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to switching means for three-phase relays or switch gear
IPC: H01H9/56
Filed: 1953-09-08
Abstract: 752,084. Arcing-preventing in switches; mechanical switches; thermal switches. SIEMENS - SCHUCKERTWERKE AKT.- GES Sept. 8, 1953 [Sept 8, 1952], No. 24820/53. Class 38(5) A three-phase relay or switch has an actuating winding for initiating the successive and synchronous opening by mechanical means of pairs of contacts in the three phase lines and is associated with switching means for selectively connecting the actuating winding to the lines. The threephase relay or switch may be arranged so that the contacts in two of the phases open 90 electrical degrees after those in the other phase and it is stated that by a suitable choice of.the connection of the actuating winding to the lines of the three-phase supply a substantially synchronously operating arrangement can be obtained. The switching means for making this choice may comprise a manually operated switch, - Fig. 1, with an operating knob 3, three contact discs 4, 5, 6 each having an interconnected pair of contacts 7, 8, or 9, 10 or 11, 12 and being displaced 120 degrees in relation to one another, fixed contact arms 13, 15, 17 connected respectively to the three phases, and fixed contact arms 14, 16, 18 connected to the actuating winding (not shown). This manually operated switch is turned to the position such that when the three-phase relay or switch is opened minimum arcing results. Fig. 5 shows an arrangement in which the switching means is operated automatically and comprises a bimetallic strip 22 responsive to the heating of the metal wall 21 of an arcing chamber of the three-phase relay or switch. Should excessive arcing occur, the strip 22 deflects and through a toothed segment 29 and pinion 32 stresses a coiled torsion spring (not shown) interconnecting the pinion 32 and a ratchet wheel 34, until the torsion spring overcomes the action of detents 61, 62 latching a disc 38 which has a pawl 35 engaging the wheel 34. The consequent rotation of the disc 38 to its next position causes the movement of contact-carrying discs such as those of Fig. 1 into a position in which the actuating winding is connected to another phase.
