Abstract: 332,836. Universelle Cigaretten-Maschinen Fabrik J. C. Muller & Co., and Neff, J. Oct. 16, 1929. Wrapping and packeting cigarettes.-Cigarettes are wrapped in two strip wrappers, the second of which is applied at right angles to the first, and are inserted in packets or cartons. A group G of cigarettes is fed by a plunger 2 between guide bars 1, 1<1>, and carries a wrapper strip E with it into a pocket 3 of a turntable 4. The strip is severed by knives 6 and held by jaws 7 until engaged by the group. The turntable is intermittently rotated by a crank 13 and pawl and ratchet gearing 9 - - 11. The downwardly projecting end of the wrapper strip is raised into a horizontal position by a stationary folder 14 during the first intermittent rotation of 60‹, and arrives over a folding flap 15, Figs. 1 and 4<a>. The flap is pivoted at 16 to a vertically movable slide, and is actuated, by rack and pinion gearing 16 - - 20, to turn first into a vertical position during the ascent of the slide, and then through a further right angle to lay the strip on the upper surface of the group. The cover plate 24 is cut away at 24' to allow the flap to make the last turn. The actuation of the slide 17 is effected by a cam surface 23 formed on the support 11 of the pawl 10 during- the return movement of the support. The partially wrapped group of cigarettes passes beneath a plunger 25 and over a strip 50 of foil severed by knives 35, being temporarily supported by resilient flaps 32. An open packet 51 is fed along a track 37 by a plunger 38 and is supported on a plunger 39 forming an extension of the feed track. The plunger 25 descends and forces the group of cigarettes and foil into the packet, the resilient flaps 32 yielding and assisting the insertion of the charge. A folding finger turns down one end of the strip upon the cigarettes, and, during its movement in the direction of the arrow C, Fig. 1, the other end is turned over by the upper edge of the feed channel. The packet may now be closed and wrapped.

Title: Improvements in and relating to electric furnaces
IPC: H05B7/00
Filed: 1919-12-19
Abstract: 160,529. British Thomson - Houston Co., Ltd., Hastings, H. C., and Laycock, N. Dec. 19, 1919. Electrode furnaces.-In a furnace installation having for each current phase two arcs in series, regulated in accordance with current and pressure respectively, a device is added for preventing the current-controlled motor from feeding when the pressure is abnormally high, as when at starting the current-controlled electrode meets the charge, and another device prevents lowering of the pressure-controlled electrode when the current is abnormally high, as when the charge caves in. Excessive current may also cause one electrode or both to be raised more rapidly than usual. As shown, a series transformer 13 supplies current to a magnet 12, controlling a motor 4 for an electrode 3 through relays as described in Specification 119,228, and to an additional relay magnet 62, which can open a circuit adapted, when excited, to cause lowering of the pressure-controlled electrode 3' by means of a similar system of relays (not shown). This circuit and another for causing raising of the electrode 3' are ordinarily controlled by the pressure electromagnet 61. In series with this is a magnet 20 which can open the circuit 16 controlled by the current magnet 12 for lowering electrode 3. An insulated section of the contactarm of magnet 62 may normally connect two contacts in a circuit containing relay magnets which close resistance circuits shunting the motor armatures; breakage of the first circuit owing to excessive current then causes the opening of the resistance circuits and increased speed of the armatures. These relay magnets also open additional switches in the circuits which cause lowering of the electrodes. In Fig. 1, one of the armature-shunting circuits 71, 72 is shown, but is kept continuously closed by an electromagnet 70 across the direct current mains 39. A braking resistance circuit 52 across the motor armature 4 is closed by a shunt electromagnet 49 when current is cut off from the motor. Mechanical interlocks 54, 56 prevent closure of either of the reversely-connected motor relay switches 57, 43 while the braking circuit is closed. In shunt to the primary current electromagnets 12, 62 is a rheostat 68 for adjusting their action. The shunt circuit across the electrode 3' and hearth 2 through magnets 20, 61 contains a resistance 29, 30, one section of which is short-circuited by a switch 33 when the mechanically-coupled switch 28 is moved so as to reduce the electric pressure of the furnace current.

Abstract: 662,420. Moulding-machines. DEHN, S. G. (Pettibone-Mulliken Corporation). Dec, 13, 1949, No. 32005/49. Class 83 (i). In a moulding machine of the type in which a rotary sand projector 29 is carried on a horizontal arm 28 pivoted to the end of a horizontal jib 27 which is pivoted to a fixed standard 26, as in Specification 565,861, [Group XXXVI], the projector is moved into any desired position by hydraulic means including a hydraulic actuating unit extending between the jib 27 and standard 26. A lever 80 pivoted to a fixed base 213 controls two hydraulic cylinder and piston units 76, 77, the former being pivoted to an arm 88 fixed to the standard and to a lug 95 of the jib and the latter to the jib and arm. The hand lever 80, Fig. 15, is mounted to move in any direction from the vertical in which it is held by a spring 225. These movements produce axial and rotary motion in a rod 240, the first causing a crank-lever 250, 253, Fig. 12, to turn about a vertical pivot 255 to move a rod 251 axially and operate a valve 78 controlling a piston 82, Fig. 9, connected to the jib 27, its cylinder 81 being pivoted to the arm 88. Rotary movement of the rod 240 acts, through an adjustable link 266, Fig. 13, on a lever 260, pivoted at 265 on the lever 252, to operate a valve 79 controlling a piston 100, Fig. 9, connected to the arm 28, its cylinder 99 being pivoted to the jib 27. The pump 145 which delivers pressure oil to the valves'78, 79 draws the oil through filters 164 from a compartment 157, exhaust oil being returned to a compartment 154 whence it can pass through perforated plates 151, 152, 153 to compartment 157. Flexible pipes are used where required. The lever 80, valves and pipes are arranged so that the movements of the projector 29 copy those of the lever. This and the piston rods are protected from sand &c. by bellows-type sleeves 235. Byepass valves 207, 209, Fig. 9, prevent sudden stoppages of the movements of the arm and jib.
