Abstract: 1,072,483. Steam turbines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 16, 1964 [March 28, 1963], No. 12365/63. Heading F1T. At least some of the interstage guide blades of a steam turbine have blade surfaces formed with slots which intercept erosive particles travelling along the blade surfaces. The erosive particles are passed to a region maintained at a lower pressure than that existing in the condenser. The invention is described with reference to an axially opposed double-flow steam turbine, Fig. I (not shown). As shown in Fig. 2, each blade 13 of a ring of hollow guide blades is mounted in and communicates with radially inner and outer manifolds 17 and 19 respectively. Either the concave blade surface 13A or the convex blade surface 13B or both, Fig. 4, are provided with slots 21 and/or 31 respectively, formed near the trailing edge 13T of the blade and extending inwardly from the radially outer end thereof for approximately half (or at least one third) the length of the blade. Steam passing through the slots entrains any water flowing along the slotted parts of the blade surface and this water passes through a drain hole 23 in the lowermost part of manifold 19 to a region maintained at a lower pressure than that existing in the condenser. In a modification, Fig. 5 (not shown), a hollow guide blade is provided with two radial rows of slots. The inner and outer manifolds and the interior of the blade are divided by a partition into two compartments, each of which communicates with one row of slots. The compartments are connected to two different points (one of which can be the condenser) for the disposal of collected water providing different degrees of suction appropriate to the respective positions of the rows of slots. In another modification, Figs. 6A, 6B (not shown), a ring shaped, external partition is fixed to the trailing edges of a ring of guide blades to divide the flow into two annular streams and internal partitioning means, similar to those used in the embodiment of Fig. 5, are utilized. The disposal points for the condensed water in this case are a feed water heater and a vacuum pump having its outlet connected to the condenser.

Abstract: 1347641 Granulating drum ALLIS-CHALMERS CORP 20 March 1972 [24 March 1971] 12922/72 Heading B5A A balling drum 10 is provided with an additional discharge outlet located upstream (Zone B) of the discharge outlet 39 and comprising one or more parts 32, 32<SP>1</SP> extending helically of the drum and oriented across the angular path of the load material flow so that they intercept and discharge a predetermined portion of the total flow.  Fig. 6A and 6B show a developed view of the interior of Zone B. The drum is rotated clockwise looking from the feed end so that the pelletized material moves along a helical path having the angular direction shown in Fig. 6A, by the line XX. The intercepting edge of the two slots 32, 32<SP>1</SP> lies along a line YY which intersects XX at an angle chosen so that a predetermined portion of the material is discharged and evenly distributed on to a conveyer below. The spacing between slots measured normal to the direction of material flow is such that the ratio of the distances D-1 and D-2 (Fig. 6B) is substantially the same as the ratio of the material to be discharged at this outlet to that passed on for discharge at the end of the drum. An adjustment of about 10% is made to compensate for the overspill due to the angle of repose of the pelletized metarial. The drum is mounted on rollers 16 and driven by a motor 18 through gearing 20, 24, and the pelletized material is discharged on to vibrating sieves 28, 30, the undersized particles being recycled via conveyer 26.

[Class 40 (ii).] Comprises winding mechanism for the spring motor of a gramophone wherein two levers are reciprocated towards and away from one another, the levers simultaneously producing a uni-directional winding of the spring motor. A turntable spindle 3 is driven by a spring motor 4 and on the shaft 5 of the motor 4 is mounted a ratchet wheel 6, engaged by a pawl 7, and two discs 8, 9 whose end faces are provided with oppositely-inclined teeth. The teeth of two loosely-mounted discs 14, 15 engage with the teeth on the discs 8, 9, respectively, and to the discs 14, 15 are connected two stepped wheels each of which includes two toothed portions, 10, 11 and 12, 13 respectively. A spring 16 tends to press the discs 8, 14 and 9, 15 into engagement. The shaft 5 is driven through the action of two pairs of toothed sectors 17, 18 and 19, 20, respectively, one sector of each pair having internal teeth whilst the other is toothed externally as shown by Fig. 5. The sectors are arranged so that an internally-toothed sector of one pair and an externally-toothed sector of the other pair are always in engagement with a pair of the stepped tooth wheels 10, 11 and 12, 13. The unit comprising the toothed sectors 17, 18 is secured to a hollow shaft 21 on which is mounted an actuating lever 23, and through the hollow shaft 21 passes a shaft 22 secured to the toothed sectors 19, 20 and on which is mounted an actuating lever 24. In operation, when both levers 23, 24 are moved inwardly the wheels 10, 11 are driven by the sectors 17, 19 and, through the members 8, 14, the drive is transmitted to the shaft 5 to wind the spring motor 4. Meanwhile, the discs 9, 15 run idly as their teeth ride over one another by reason of their inclines. When the levers are rocked apart; the discs 9, 15 are brought into driving engagement and the shaft 5 is wound in the same direction as before. A modified arrangement is described in which the levers 23, 24 are rocked about separate axes of rotation.

[Class 40 (ii)] In a magazine gramophone for playing records of mixed sizes, the pick-up is lowered in position to commence playing a large diameter record and if a small record is in playing position is ' traversed inwardly to correct starting position by a roller 10 mounted on the pick-up arm with its axis of rotation non-radial to the turntable, the roller being driven by engagement with the rotating record. The pick-up needle 6 depends just below the periphery of the roller 10 and is spaced from the roller by a distance at least as great as the greatest difference in the radii of the records to be played. Thus, on lowering the pick-up, if the pick-up does not land immediately on the edge of the record to be played, it will be swung inwardly till it does, and then roller 10 will be raised off the record. Holler 10 is mounted eccentrically to cause the pick-up to undulate as it is traversed on to a record so that the needle may clear the edge of the record readily. The roller may also be formed with a spiral rib to enable it to ride up the edge of a record, and may be fitted with a spring brake 14.
