    Abstract: PCT No. PCT/GB92/00800 Sec. 371 Date Nov. 2, 1993 Sec. 102(e) Date Nov. 2, 1993 PCT Filed May 1, 1992 PCT Pub. No. WO92/19546 PCT Pub. Date Nov. 12, 1992.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 area 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: A device for locking an article to a construction, comprises a body portion securable to a suitable element of the construction. A clevis has limbs which are expendable through co-operating apertures in the article and thence into said body portion. Locking means in the body enable at least one limb of the clevis to be lockingly held in said body portion, thereby preventing unauthorized removal of said article from the construction.

    Abstract: 18,701. Todd, J. Aug. 15. Bulk evaporators.-A salt pan having a number of furnace flues b below it is fitted with chambers f, f connected by pipes h immersed in the brine, the arrangement being such that the whole or part of the flue gases pass upwards to the chamber f, through the pipes h to the chamber f , downwards to the flues, and finally to the chimney. The brine is preheated by passage through pipes d of flat or oval crosssection arranged in the flues b. The pan may be heated by the hot flue gases from pans of ordinary construction, the gases being led from the old pans to the chamber f.

    Abstract: 5341. Todd, J. S. March 2. Tie-bars ; sleepers, composite.-Pot sleepers a are connected by tie-bars f having at each end one or more open-ended slots k or slots engaging the holding-down bolts e of the chairs &c., to allow the tie-bars to be disconnected without removing the chairs &c. The slots k may be on one or both sides of the barf, and either straight or arcuate. The tie-bar may be protected in the centre by tar or by concrete, which may be reinforced by a coil g of barbed wire, attached at each end to the bar. A recess is provided in either the chair or the sleeper or both to receive the tie-bar. To secure an elastic connexion, either the tie-bars or the recesses may be curved. The ends of the tie-bars are flat but the centre may take any shape. The sleepers, if of concrete, may be reinforced by two wire coils b, c, which may either be friction tight or be tied together.

    Abstract: 16,233. Todd, J. S., Wade, F. R., and Jones, J. R. July 15. Chair keys and wedges of flexible sheet steel are used in pairs and tightened by a bolt, projections, holes, or recesses on or in the keys engaging holes or studs in or on the rail web. The keys a, Fig. 2, have their upper ends bent to abut against one another as shown also at l in Fig. 7 are formed with a shoulder i to abut against the chair, and are drawn together and their arched sides g flattened by a bolt c provided with locking nuts or washers, or both. For rail joints, the ends are placed in the chair and the key is tightened, and a projection x may be formed on each key part to take into holes in the rail end as shown in Fig. 11. To prevent creeping, a stud t, Fig. 7, preferably at the centre of the rail, is placed in its web to take between the abutting key ends t ; or the stud may be lengthened to separate the ends l. A plain or screwed setscrew or stud v, Fig. 10, in the key, placed there before the bolt c, may take into a hole in the rail web ; or each key part may be provided with such a screw taking into separate holes in the rail web ; or the projections x, Fig. 11, may be formed at the abutting corners of the keys and take into one hole in the rail web.
