Abstract: 1,241,313. Treating gases with liquids. MONSANTO CO. 19 Aug., 1968 [25 Aug., 1967], No. 39520/68. Heading B1R. [Also in Division F4] An upwardly flowing gaseous mixture containing a sublimed solid is cooled by countercurrent contact with a descending stream of liquid in a contacting tower 6 which is provided with a series of vertically spaced inclined baffle trays 19-21. The sublimed solids, which condense out onto the trays, are washed downwardly by the liquid stream. As shown the gaseous mixture, which is supplied from a dehydrator 4, contains cyclohexane and sublimed ortho boric acid together with nitrogen and water. On leaving the tower said mixture passes through a condenser 8 and thence through a phase separator 10 wherein the nitrogen and water are removed. The liquid cyclohexane stream leaving the phase separator is then subdivided, part being recycled to the dehydrator 4, and part entering the tower through line 14 to constitute the descending liquid cooling stream. Said liquid stream leaves the tower bottom through a line 16 and is fed by a pump 17 through a line 18 to cyclohexane oxidation apparatus (not shown).

Abstract: 1529794 Two-electrode reference system for cathodic protection MORGAN BERKELEY & CO Ltd and J H MORGAN 2 Dec 1975 [12 Sept 1974] 39884/74 Heading G1N [Also in Division C7] A reference electrode system for use in cathodic protection of a metallic structure in contact with an electrolyte comprises a pair of reference electrodes insulated from and mounted on the structure adjacent one another and having different electrolytic potentials which are substantially stable in the electrolyte, the electrodes being connectable to a circuit which monitors their relative potential. Thus, if this changes, damage to one or both reference electrodes can be assumed; this precludes the necessity of routine visual inspection of reference electrodes, e.g. on an oil rig. The electrodes are used to monitor the potential of said structure, to discover when sacrificial anodes are consumed, or to determine the impressed current voltage required for protection. The electrodes, one of Zn and the other of Ag/AgCl may be encased in an insulating backing and mounted to a structure by an insulated metallic bar; a wire from the electrodes may pass through the wall of the structure.

Abstract: 906,481. Rotary I.C. engines. AUGUST, P. Nov. 25, 1960 [Sept. 20, 1960], No. 40544/60. Class 110 (2). Air, or an air-fuel mixture, enters the precompression stage (Fig. 2) of an I.C. engine by inlet 15, is compressed by cylindrical piston 12 carried on eccentric 10 and passes through passage 16 to the main compression stage comprising a reciprocating piston 25 and spring- loaded counter-piston 26. As the air or mixture is compressed further, passage 16 is closed by piston 25 and ignition takes place. The counter piston 26 moves back to uncover channel 31, and the combustion gases pass into the expansion stage, where work is extracted by blade piston 4 and eccentric rotor 5 before the gases exhaust through exhaust opening 37. The expansion ratio may therefore be greater than the compression ratio, and in the embodiment described is 1.4 to 1.5 times greater. The crank-shaft 23 of the main compression stage is connected to the driving shaft 2, and rotates at the same speed as the latter. The counter piston 26 may alternatively be cam operated. The piston and rotor of the expansion stage are sealed by fillets 35 and 36 and by cylindrical roller 32. The engine is cooled both by water and by air blown through the hollow centre around the shaft 2. Specification 905,865 is referred to.
