Title: Improvements in metallurgical furnaces comprising stirring windings
IPC: H05B6/34
Filed: 1950-05-16
Abstract: 673,265. Electric furnaces; stirring. ALLMANNA S V E N S K A ELEKTRISKA AKTIEBOLAGET. May 16, 1950 [May 24, 1949], No. 12164/50. Class 39(iii) A metallurgical furnace, e.g. an arc furnace, an open hearth furnace or a mixing crucible has on its base a polyphase winding for stirring the contents fed by a current of a frequency of about one cycle per second for producing a movement in a certain direction in the molten content by co-operation between the flux created by the winding and currents induced by the flux, and the direction of the stirring movement is altered by arranging the phases of the winding that the geometrical direction of the distance from one phase to next succeeding it in time can be altered relatively to the furnace. This is effected by rotating the furnace on a vertical axis above a fixed coil, by rotating the coil beneath a stationary furnace, or by changing the connections between the current supply and the coil, especially for a twophase supply. The furnace body 1 is supported by a circular bar 8 and is rotated on rollers 7 by a motor 9. The stirring windings are constructed as described in Specifications 499,437 and 601,073, are fixed in a shell 10 on a non-rotating base 6 and may have iron cores. The non-rotating roof 2 carries electrodes 3. The furnace 1 has a tapping spout 4 and a charging opening 5 and is supported on a tilting base 6 In a modification, the furnace is fixed to the tilting base 6, and the stirring winding and its shell 10 rest on a circular bar supported by rollers 7 so as to rotate beneath the furnace. When current is supplied from one or more commutating A.C. machines, the brush position on one or more machines may be changed.

IPC: B21H1/02
Filed: 1925-05-12
Abstract: 247,796. White, A. E., (Budd Wheel Co.). May 12, 1925. Rolling discs; tapering by rolling.- Tapered metal discs are formed by successively rolling superposed square or rectagular blanks in radial direction from the centre outwards. Figs. 8 and 9 shows a pair of blanks which have been passed once through the rolls 12, Fig. 1 so that the parts 26 are tapered and form part of each disc. The rolls 12 are provided with segmental dies 18 secured in the roll surface the edges 19 of the dies being bevelled to prevent the formation of ridges. The taper in the disc is formed by setting each die segment so that the distance of its surface from the roll axis increases continuously from apex 21 to the base. The working face of the die is slightly concave to effect uniform circumferential tapering of the finished disc. Each roll is provided with collars 11 which roll on one another but which have eccentric inserts 23 along part of their periphery to separate the rolls for facilitating the insertion of new blanks. After the blanks are formed to approximately circular shape, Fig. 13, the edges are trimmed to a true circle. Specification 146,074 is referred to.

Filed: 1924-05-23
Abstract: 218,258. Compagnie d'Applications MÚcaniques. June 28, 1923, [Convention date]. Brakes, arrangement and disposition of.-Relates to brakes for the steering wheels of motor vehicles of the kind in which the shaft 7 of the' actuating cam 6 is provided with a universal joint 20 thereby permitting the one axis of the joint, in the release position of the brake, to be maintained parallel to the steering pivot 2 so that no rotation of the shaft and movement of the pedal results from the steering movement of the wheels. The Specification as open to inspection under Sect. 91 (3) (a) states that, with the universal joint 20 disposed as above described, steering movement of the wheels with the brakes applied effects a variation in the angular position of the cam 6, which results in a differential braking action on the brakes of the two wheels. This subject-matter does not appear in the Specification as accepted.

Abstract: 543,364. Packaging. WILLIAMS, V. G., GRANGE, E. R., and DELAMERE, R. D. Aug. 14, 1940, No. 12980. [Class 94 (i)] A machine for packaging articles, particularly for making and filling tea bags and providing them with tags. comprises a rotary hopper with measuring chambers, a number of nozzles which receive charges of material from the measuring chambers, means for forming a strip of fabric into bags to receive material from une nozzles, and means for separating the bags and sewing them along their sides and mouths. The machine comprises an endless chain 2 passing in a horizontal path around two sprocket wheels 3c, 3d journalled at opposite ends of a bridge 3 that supports the chain, the sprocket 3c being secured to a driven shaft 3e. Grippers 4 are mounted on the chain in such a manner that they can be swung in a vertical plane and rotate in an horizontal plane, and they are opened and closed periodically. Nozzles 28 are mounted on a second chain 22 which passes around a sprocket wheel, secured to the shaft 3e, and an idler sprocket 24. During part of the movement, each nozzle is coaxial with a gripper 4, and is moved vertically on its carrier by a cam so that it is lowered into a gripper and then raised from it while they are coaxial. Bag-making fabric 9a is drawn from a roll 9c through the open grippers and folded longitudinally into V-shape. The folded material receives the descending nozzles and is clamped around them by the closing of the grippers. The latter then pass beneath a spout 21. to receive filling material, such as tea, from a hopper 8 secured to the shaft 3e.  The hopper is provided with measuring chambers 8f, Fig. 4, which communicate one by one with the spout 21 and deliver into it a measured quantity of tea. In order to maintain a pre-determined level of tea in the hopper, the tea is received from a spout 8v which is,closed by a pivoted plate 8w. The free end of the plate carries a plate 8z adapted to be engaged by the tea in the rotating hopper, and is moved by the tea to keep the spout 8v closed. If the level of the tea falls below the plate 8z, a spring swings the plate 8w aside and opens the spout 8v to admit more tea to the hopper. A knife 11, Fig. 2, severs the fabric between adjacent closed grippers to form bag sections 9 each of which is carried by a gripper. After filling, a nozzle is raised out of a bag section and this is carried by the gripper past or sewing machines 15, 15a, 15b, 15c, Fig. 1, which trim and sew the sides and mouth of the bag section, and also attach a tag 17, Fig. 18. The tags are fed to and sewn into the stitching which is then cut between adjacent bag sections. Finally, each gripper is opened and turned through a right angle, and the bag is removed by a rotary clamping-device 34 and dropped on to a conveyer 20.
