Abstract: 14,043. Todd, J. S. June 15. [Cognate Application, 17,046/09.] Sleepers, composite ; sound and vibration. preventing.-R e i n f o r c e d concrete sleepers are composed of two transverse ties or bars formed with integral bridge-pieces in line with the rails to support the rail ends. The transverse ties or bridge-pieces, or both, may be extended. Packing of wood, metal, felt, 'Willesden canvas,' &c. may be used. The ties may be widened at the ends, and for crossings &c. they may be connected by more than two bridge-pieces. The cross-section of the ties and bridge-pieces may be rectangular, or they may be broader at the bottom than at the top, with slanting sides or with a set-off ; and the bottom may be formed with ribs and grooves or projections and depressions. The reinforcing-rods of iron, steel, &c. may be round, square, flat, &c., and they may be straight, undulating, or twisted. One modification of the sleeper is shown in Figs. 13 and 14.

Abstract: Granules of plastics material have grains of an inert mineral such as sand coated thereon to provide a habitat for microorganisms effective in waste water treatment, the granules having a predetermined particle size range, and the grains having a predetermined particle size range and being disposed at a predetermined packing density range on the granules. The particles have an average density of approximately 1.0 g/cc such that a proportion tend to float and a proportion tend to sink in the waste water. The particles arc manufactured by contacting the granules of plastics material with a mixture of grains of the inert mineral and grains of a soluble substance such as salt, at an elevated temperature, to coat the granules with the mixture, and subsequently dissolving the soluble substance grains from the coating to provide the granules coated with the grains of inert mineral in the predetermined packing density range.

Abstract: An apertured flexible membrane (10) extends over a domed support (11). A central gas supply tube (50, 82) terminates in gas outlets (51) oriented to direct the gas to flow horizontally into the space (40) between the membrane and the support to inflate the membrane away from the support so that gas from the inflated space discharges through the apertures (60) as fine bubbles and such that when the gas supply ceases the membrane collapses back into ar ea contact with the support to seal all the apertures. This reduces clogging. The aerator is useful in the aeration of sewage or waste water and in fish or eel farms.

Abstract: Granules of plastics material are coated with a mixture of sand and salt grains by tumbling and heating a mixture of grains and plastics granules by passing them along a heated rotating hollow tube 1. The grains and plastics material granules are fed from hoppers 7,8, mixed by rib(s) 6 and heated to a temperature not less than the softening temperature of the plastics granules by a heater 5 . The coated granules are then tumbled and cooled before leaving the rotating hollow tube. The salt grains may then be removed by washing, to form a waste water treatment medium.
