[Also in Division B8] Batteries 1 are fed by conveyer 19 to rotary transfer turret 17 which turret 17 feeds the batteries in sequence to processing turret 12, transfer turret 15, processing turret 13, transfer turret 16, processing turret 14 and thence via transfer turret 18 to the discharge conveyer 20. Each turret is provided with a plurality of carriers each adapted to carry a battery and articles are discharged therefrom by stationary elements 36, 46, 51, 63, 68 and 69 respectively. Feeding to conveyer 19, Fig. 3, not shown.- Each battery 1 is fed to transfer turret 17 from conveyer 19 by pusher 26. Thus a battery on conveyer 19 operates switch 23 to release pusher 26 and to operate finger 28 to engage and hold up the next battery. Turret 17 then causes pusher 26 to operate and to push a battery past shutter 27 (now in the lowered position) into carrier 22 of turret 17. Screen 24 pivoted at 25 operates when a battery is mis-orientated to stop the apparatus. Processing turret 12 (Fig. 5.)-Three separate processing means for the battery are mounted on the turret. The first means aligns the cells of the battery and comprises pressure exerting device 37. The second means applies a drop of pickling solution to each terminal of each cell and comprises pivoted arm 38. The third means inclines the blades of the cells and comprises lever 39. As the battery rotates on the respective carrier 34 of the turret the three means successively operate thereon, the arm 38 working in conjunction with fixed tank 42 containing pickling solution. Second processing turret 13 (Fig. 6).-This mounts a fourth means which causes the blades of the cells to engage the adjacent terminals, and also a fifth means adapted to solder the blades to the terminals. Again, the third processing turret 14 mounts a sixth processing means which tests the strength of the solder connections, and a seventh means for measuring the voltage. Fifth processing means (for soldering), Fig. 6.- As a battery rotates on a carrier 49 of turret 13 peens 55 pivot relatively to arm 53 carried by the turret 13 and dip into stationary pickling tank 56. The turret continues to rotate till arm 53 reaches position 58 at which peens 55 dip into solder tank 57. Finally, when arm 53 reaches position 59 the peens are lowered on to caps 6, 8, 9 of the battery to solder them. Reject device (Fig. 8).- If the voltage testing device of turret 14 detects a faulty cell the battery is subsequently discharged from the last turret 18 by the operation of electromagnet 78 which causes pivoted member 79 to actuate the appropriate finger 75 carried by turret 14, the finger actuating expelling means 82 pivoted at 83 to expel the defective battery into container 87.

Abstract: 986, 231. Electric selective signalling; road signals for controlling traffic. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 29, 1963 [April 12, 1962], No. 14247/62. Headings G4H and G4Q. Devices are actuated on receipt of individual control frequencies provided a calling frequency common to the devices is received in parallel with the control frequencies. A central station is connected to separate locations 1--n by a transmission line T. In Fig. 1, consider for example the group of devices A, I, F at location 1. Detection of the group-calling-frequency f1 on line T by receiver RX1 results in energization of relay R1 to connect line T to the individual receivers RA1, RI1, RF1 each of which, if its respective control frequency is present, will energize a relay AR1, IR1 or FR1 to actuate device A, I or F. These devices may be road signs indicating hazards, the signs being displayed by illumination or movement (either of the sign or of a covering mask). Holding circuits for the energized relays AR1, IR1, FR1 are established, keeping the signs displayed, but are broken the next time relay R1 is energized. Slow-release relays may be incorporated in the actuation circuits of the devices A, I, F. Fig. 2 (not shown) shows an alternative embodiment suitable for use when the signs are of a type not requiring energy to maintain them in a displayed (or undisplayed) state once this is established. In Fig. 2, the holding circuits are broken as soon as all the signs are in the required state. In either embodiment, a given sign is changed to the undisplayed state on reception of the group-calling- frequency without the sign's control frequency. Fig. 3 (not shown) shows the control station with arrangements of switches for controlling frequency generators. Other arrangements of switches are described. When a transmission is made from the station, a delay relay is energized to produce an audible tone after a time sufficient for the signal to have reached the locations 1--n. The possible use of the invention in railway signalling is also mentioned. Specifications 869,896 and 961,091 are referred to.

Filed: 1927-05-28
Abstract: 271,903. Preparation Industrielle des Combustibles Soc. Anon. May 29, 1926, [Convention date]. Roller-and-breast mills; impact pulverizers; feeding-devices for granular and like materials.-In apparatus for crushing and feeding pitch to mixers, the large lumps of pitch are crushed in a mill having a single cylinder and then transferred to a Carr grinder which comprises a casing surrounding the lower parts of rotating plates provided with scrapers which cause the crushed pitch thrown out by centrifugal force to fall on to the casing. The pieces of pitch are fed by a hopper 1, Fig. 5, to the crusher 2, whence they are delivered by a distributor 3 to a Carr grinder 4, the rotating plates of which are provided with scrapers and surrounded at the lower part by a casing 9. The crushed particles are received by a pipe 11 to the feed-shoot of the grinder 4 and delivers it into a cylindrical hopper 7 which feeds a distributing-device 8. A steel member 13 carried by a slowly-rotating vertical shaft 14 scrapes the walls of the hopper 7 and directs the pitch to opening 12. A plate 17, Fig. 1, with openings 22 is rotated on a vertical shaft 16 carried by a base 15 by means of bevel gearing 18, 19 from a driving-shaft 20, and pistons 27 are arranged to move vertically in the openings 22. The pistons 27 are carried by shafts 28 which are mounted in members 26 bolted to the plate 17 and carry at their lower ends rollers 29 running on a path 30. Part of the roller path consists of a vertically-displaceable member 30<1> mounted on screwed rods 32 engaging members 33 that can be turned by gearing 34, 35 operated by means of a handle 31, Fig. 4. A pointer 36 working over a graduated scale 37 indicates the position of the movable element 30<1> of the roller path 30. When a roller 29 of a piston is located on the element 30, the corresponding opening 22 is situated beneath the filling- opening 38 of the mixing-device and filling takes place. As the plate 27 rotates, the roller passes from the element 30<1> on to an upwardly-inclined part of the path 30 and the piston is moved upwards. The roller then travels over an horizontal part of the path 30 and down an incline to the member 30<1>. A scraper 40 causes the material which has been pushed up through an opening 22 by the piston to fall into a shoot 41 leading to the mixing-apparatus. Leather bellows 49 held at one end against the collars 23 of the pistons and at the other end against the members 26 prevent dust from entering the bearings of the shafts 28. A flange 51 on the member 26 runs in a trough 52 carried by the base 15, the trough being filled with oil or coal dust to form a tight joint.
