Abstract: 801,259. Rotary tipplers fitted with vibrators. BUTTERLEY CO., Ltd., and WESTMORELAND, A. G. March 13, 1957 [March 1, 1956], No. 6501/56. Class 78 (4). A vibrator for jolting tubes in a rotary tippler supports the tubs when they are inverted. As illustrated the vibrator comprises longitudinally extending casings p, q (Figs. 2 and 4) joined by transverse members s and mounted by springs 5 and by rollers u in the tippler cage so that portions t (Fig. 2) support the tubs when they are inverted. Each member p, q includes a pair of unbalanced pinions v, w (Fig. 4) weighted so that there is no horizontal unbalance and driven through shafting 6 and belting 8 from a motor 7. The motor 7 may be supplied with current through slip rings in the axle of the tippler or, where the tippler does not make a complete revolution, through a cable 9 (Fig. 3) carried by a guide 10 extending from an eccentric pivot 10a on the tippler and supported by a pivoted strut 9a. The tippler is driven through one pair of supporting rollers b which may have teeth to engage the corresponding end ring and the control of the tippler and of the vibrator may be partly automatic. The brake blocks f shown can be moved by a lever g (Fig. 2) into engagement with either of two shoes g<SP>1</SP> when the tippler is erect or inverted.

Abstract: 653,005. Artificial lines. GENERAL ELECTRIC CO., Ltd. March 4, 1948, No. 6787. [Class 40 (viii)] An artificial line with characteristic varying with the electrical length along the line comprises two conductors with capacity between them approximating to a smooth distribution of capacity, one of the conductors forming a coil with mutual inductance between the turns. In one embodiment, condensers of varying capacity are connected at regular intervals between an earthed metal sheet and a coil with regular pitch and diameter, Fig. 3 (not shown).

In another embodiment, Fig. 1, a coil 1 of metal strip is wound on a former 2 of rectangular cross-section and varying height. A metal sheet 4 separated from the flat base of the coil by a dielectric sheet 5 forms the second conductor of the line. A balanced line may be formed by two coils of metal strip wound on similar formers with their flat bases separated by dielectric, or by arranging two unbalanced lines with the metal plates a small distance apart and connected together.

[Also in Group XXVII] In a steam turbine plant for marine purposes having a main turbine 1 permanently connected to the main drive of the propeller shaft 4 and an auxiliary turbine 6 of lower power rating drivingly connected by an automatic clutch 8 with a shaft geared to the main drive, the clutch is responsive to the relative speeds of the auxiliary turbine and of the shaft driven by it so as to clutch in the auxiliary turbine when its speed exceeds that of the driven shaft and to declutch it when the said shaft runs faster than the auxiliary turbine. A second auxiliary turbine 7 is coupled to the turbine 6 by a like speedresponsive clutch and may, if desired, have a third auxiliary turbine 19 likewise coupled to it. The auxiliary turbines are designed for increasing power output and are adapted to be brought into operation one after the other by a hand wheel 23 which controls the inlet valves of the turbines through the gear and cam means shown. The turbines 19, 7, 6 exhaust through the lowpressure stages of the turbines 7, 6, 1 respectively and crank the main turbine 1. In a modification, the turbines 7, 8, 19 are dispensed with and in a further modification the turbine 19 is coupled to the turbine 1.

Abstract: 561,238. Stopping and starting mechanism. A.C.E. MACHINERY, Ltd., and EVANS, P. N. June 2, 1942, No. 7474. [Class 80 (ii)] [Also in Group XXXIV] Movement of a hand lever in either direction from a central position actuates a spring- pressed lever carrying a brake shoe to disengage the shoe from a drum and simultaneously displaces the drum to engage it with one or other of a. pair of oppositely rotating friction driving pinions by which it is driven in the corresponding direction. As shown, the drum 1 which is coupled to a gear member by which it transmits the drive to the apparatus under control rotates upon a shaft 3 mounted in eccentric bearings 2 in fixed frame members 10, 11 and the shaft with the bearing members 2 can be turned by a hand lever 6 so as to displace the drum to a small extent and thus to engage the interior surface thereof with either of a pair of oppositely rotating driving pinions as described in Specification 561,235. Rigid with the lever 6 is. a double arm 29 connected by rods 27 to one end of a lever 14, 15 pivoted at 16 to the base 17 and carrying a brake shoe 13. The shoe is pivoted at 18 to the lever so that it may be accommodated to the drum surface and a spring 19 is disposed between it and a lug on the lever arm 15. The shoe is applied to the drum by a spring 21 which bears on a fixed plate 22 and through a plate 25 on a rod 23 seated at 24 on the lever arm 15. The rod 23 slides through the plate 22. The brake shoe 13 is thus applied to the drum when the lever 6 is in the central position shown and is released when the lever is moved to either side to engage the drum with the one or the other of the driving pinions. The invention may be applied to power-driven cranes and other hoisting and lifting gear such as described in Specifications 561,233 and 561,239, [both in Group XXX].

A tunnel kiln for firing ceramics on trucks 3 comprises a firing zone 5 in which lateral burners 30 are disposed in vertical rows coincident with the gaps between trucks, and a preheating zone 4 heated indirectly by muffle chambers 8 with inner metal panels and directly by burners 20 each associated with a fan 11 inducing circulation of hot gases in transverse vertical planes. Hot gases passing from the firing zone through chambers 8 to chimneys 9 may be further heated by burners 20<SP>1</SP>, Fig. 2. Each fan 61 drives the gases over a partition 12 and deflectors 13 through the stacked ware 2 and over deflectors 15 to space 7, and each circuit has an air inlet 16 controlled by damper 17 and an outlet flue 18 controlled by damper 19. The burners 20 alternate on opposite sides of the tunnel and are controlled by valves 28, 29. Dampers 17, 19 and valves 28, 29 are controlled by linkage actuated by a thermostat 23. Each burner 30 has a control valve 32 and each bank of said burners an overall control 33 actuated to cut down the fuel supply when an operating ram pushes a fresh truck into the kiln, Fig. 4 (not shown). At the exit end of the firing zone 4 are vertical rows of nozzles 46, 47 directing cooling air into the kiln, the walls of which are lined with cooling tubes 48 and 49 respectively supplied with air through pipes 50 and 51 controlled by valves 53 and 54. Tubes 48 and 49 are respectively connected to mixing valves 57 and 60 which are also connected to pipes 50 and 57 and supply the mixed warm and cold air to the nozzles 46 and 47. A fuel cooling zone has indirect cooling elements 63, Fig. 2<SP>1</SP>, supplied with air by a fan 52, and fans 64 similarly arranged to the fans 11 in the preheating zone provide transverse currents of air in the tunnels. In a modification, Fig. 5 (not shown), the muffle chambers 8 are replaced by a single roof chamber to which additional heat is supplied by fuel-fired radiant tubes. Another modification, Fig. 6 (not shown), has the burners 30 arranged to discharge longitudinally of the kiln, alternate burners facing in different directions. The cooling zone may be modified, Figs. 9 and 10 (not shown), by baffles associated with the fans 64 so that air in adjacent streams is mixed to give more even cooling.
