Granted: 1902-05-15
Abstract: 12,918. Joly, C. June 25. Compressing; liquefying.-Air or other gases are compressed and expanded in a closed cycle at high pressure, between 20 and 100 atmospheres, for instance, with a view of obtaining a greater ratio of cooling effect to power expended as compared with that shown at lower pressures. The cooling effect of the expanded air or gas is used for liquefaction or for ice-making and refrigerating. In the simplest form, the apparatus used may consist of evaporating and condensing coils 6, 2, a compressor 1, and an expansion and regulating valve 4. The apparatus may be charged initially from a source of compressed air or by the compressor itself, which is then arranged to draw in air. Reservoirs may be added to the coils as at 5 or elsewhere. The spent cold air from the expansion coil may be used in the heat exchanger 3 to cool the compressed air from the condenser 2.

Granted: 1903-03-23
Abstract: 26,259. Ford, L. P. Dec. 23. Moulding artificial stone. - Relates to a method of moulding artificial stone blocks from a mixture of sand and lime, in which the ex pansion of the materials in a rigid mould in the presence of steam or water is utilized to compress or solidify the blocks and prevent cracks and " partings" therein. The mould comprises a strong outer shell formed with ¢-inch perforations about a foot apart, and a thin inner lining provided with <1>/16-inch perforations about half an inch apart. Fig. 1 shows a cylindrical mould in end elevation with the ends removed. The shell a is perforated at a' and is provided with angle-irons a<3> to which the end plates are bolted. Brackets riveted to the shell may replace the angle-irons. A butt joint a<2> is formed in the shell so that it may be opened sufficiently to free the moulded block. Castings or forgings b, b<1> are riveted to the shell on opposite sides of the butt joint, and are bored to receive the bolts c, Fig. 1, which tighten up the joint. A wedge-sectioned projection b<2> on one casting enters a recess b<3> in the other, and pins b<4> entering sockets b<5> also serve to keep the castings in correct relative position. When discharging the moulded block, the bolts c are first removed, and the opposing bolts h, Fig. 7, are then used to force the butt joint open and relax the pressure on the expanded material. Runners i prevent the mould from rolling about, and facilitate handling it. When blocks of rectangular section are required, partitions of paper, linen, &c. may be used to separate the material, which is merely used to fill up the segmental cavities from that which is to constitute the block. The aforesaid cavities may also be filled up with segmental blocks of porous or perforated material as shown in Fig. 14.
