Abstract: 816,419. Ice-making. FLAKICE CORPORATION. Feb. 27, 1958 [March 6, 1957], No. 6368/58. Class 29 In a machine for ice-making or congealing liquids in which the liquid is run on to an endless metal belt which moves over a stationary refrigerated surface, heat transfer from the belt to the surface is enhanced by applying a partial vacuum to the space between the belt and the surface. Evaporator 1 is mounted in inclined position on frames 11 by lower brackets 3 and upper bolts 7 for slight angular adjustment. It consists of a metal block in which are embedded evaporator pipes 115 and its upper surface is convex longitudinally of the belt and concave transversely of the belt. The endless belt 47 passes over lower and upper rollers 43, 45, the former being motor-driven, and has along each edge a resilient pad 59 the lower part of which seals against the side walls of the evaporator and the upper part of which forms a dam to confine the water to the belt. The upper surface of evaporator 1 is formed with _grooves 125, 126, to which glycol or other low-freezing liquid is supplied by a pump 87. The glycol being cooled by an evaporator 137. The suction side of pump 87 is connected to apertures 128 in the evaporator and thus withdrawn glycol from the space between the evaporator and belt 47 and maintains a partial vacuum in that space. A pad 139 at the upper end of the evaporator bears on the belt to prevent glycol being carried away by the belt and a second pad 153 at the lower end prevents condensation being carried by the belt into the evaporator area. Water from a tank 171 is pumped over two precooler plates 181 whence it runs on to the belt 47 through distributers 185. Plates 181 contains evaporator passages 183 the pressure in which is controlled so that their temperature is always above freezing point. Ice frozen on the belt peels therefrom as it passes over the top roller 45 and falls into a shoot 182. Liquid refrigerant is circulated through the evaporator passages 115 by a motor driven pump. The refrigerating and electric control circuits are described in detail.

Patent GB-817704-A (GB)
Title: Process for improving the bonding strength of bituminous materials
IPC: C08L95/00
Filed: 1956-03-01
Abstract: The bonding strength of bituminous binding agents to stone surfaces under the action of water is improved by incorporating in the binding agent the distillation residue of a crude phenol-containing tar or crude base-containing tar.  The residues, which can be added in amounts, e.g. up to 5 per cent. by weight of binding agent, are obtained by extracting the phenols or bases from coal tar with sodium hydroxide solution or sulphuric acid, respectively, in each case neutralising the brown liquid extract obtained and fractionally distilling off phenols or bases to leave a pitch-like residue. Alternatively, coal tar itself is fractionally distilled to remove the phenol fraction, which fraction is again distilled to remove volatile phenols and leave a phenol pitch as residue.  The residues also include those obtained from the distillation of crude phenol-containing lignite tars. Montan wax, cetyl pyridinium bromide or other tertiary base can be added to increase the bonding strength. In one example, limestone chips are coated with a road tar to which 2 per cent. of the distillation residue of a crude phenol-containing tar has been added, while in the other example a bitumen containing 15 per cent. of coal tar flux oil is used instead of road tar.
