Abstract: 1,258,407. Utilizing energy of radiations. J. CLARK. 10 Dec., 1968 [11 Dec., 1967], No. 58757/68. Heading G6P. A radio-active coating is provided on the skin of aircraft in order to reduce aero-dynamic drag. The energy emission from the coating is controlled by adjustment of the electrical biasing potential. Both beta and alpha emitting coatings are employed and the energy emission from the coating to the air is effected by emission directly into the air or by the excitation of a crystal lattice at the air boundary. In some embodiments, the radio-active material is bonded to the aircraft skin and covered with alternate layers of P and N type semi-conductive layers which have an adjustable bias to control the energy of the alpha or beta emission. PN, NP, PNP, NPN and field-effect junctions may be used. Collimation of the emission is effected by a crystal lattice layer interposed between the radio-active coating and the semiconductive layers. In an alternative form, the radio-active material is alloyed with the semiconductor by ionic bombardment.

Abstract: 1,143,640. Lixiviating apparatus. SOC. FIVES LILLE-CAIL. 21 July, 1966 [3 Aug., 1965], No. 32760/66. Heading B1Q. [Also in Division C6] In a process and apparatus for extracting a substance from highly absorbent comminuted material, a solvent for the substance is circu lated through the comminuted material and the exhausted material is then pressed to express absorbed solution, which expressed solution is purified concentrated and then circulated through the material before the solvent. In extracting sugar from comminuted, highly absorbent material, such as crushed or finely cut-up sugar-cane, the material is fed, from a hopper 24 and past a thickness-controlling member (not shown), to form a layer of a desired thickness on the upper run of the permeable, endless conveying belt 22 travelling from the hopper 24 to the discharge hopper 26 of the diffusion apparatus 10. Water is sprayed, at location 28, on to the layer. The water passes through the layer and extracts sugar from the material. The resulting dilute sugar solution passes through the belt 22 into a collecting vessel 30, from which the solution is sprayed on to the layer at a location 32, which is nearer to the hopper 24 than location 28. The 30-32 collection and circulation is repeated. Substantially exhausted material is discharged, through the hopper 26, on to a conveyer 14, which delivers the exhausted material into a working multi-roller press 12, which expresses absorbed sugar solution. This solution is defecated with lime in a tank 16 and passed into a settling tank 18, from which clarified solution is passed, e.g. decanted, through a steam-heated evaporator 20, e.g. operating under reduced pressure with a very small hydrostatic head, and preferably of the descending type. The concentrated, clarified solution leaving this evaporator is sprayed at location 34 (which is between location 32 and the hopper 24) on to the travelling layer of material, and is collected and passed downwardly through the layer, repeatedly in a manner similar to the 30-32 collection-circulation. It is pointed out that, each solution is sprayed on to the layer at a location where the concentration of sugar in the material is greater than that in the solution. Diffusion juice from the diffuser 10 is concentrated in multipleeffect evaporators (not shown), from the "effects" of which exhaust steam may be used to heat the evaporator 20.

In laying a pipe-line along a preselected route on the floor of a body of water from a pipe-laying vessel having a laterally rigid or a hinged segmented laterally flexible pipe support structure extending outboard of the vessel for directing the pipe-line into the water, the loads imposed on the pipe support structure are sensed, the vessel heading is turned in dependence of the load sensed to reduce the loads on the pipe support and the vessel is moved along the preselected route while maintaining the vessel heading in the turned attitude. The adjustments in vessel heading may be carried out automatically. The load sensed may be the sideways force on the pipe support near its outer end and/or the bending moment at the inner or outer end of the pipe support. The vessel heading may be turned sufficiently to substantially eliminate the stress in the pipe or to reverse the bending moment in the pipe-line at the tip of the pipe support. The loads may be caused by transverse water currents or by misalignment of the vessel and the pipe support with the pipe-line already laid. In a preferred method the difference between the measured force and a desired force is used to generate a heading error signal proportional thereto, the difference between the tension in the pipe and a desired tension generates a tension error signal, the deviation of the vessel from the desired route generates a route error signal and these signals are combined and applied to vessel positioning means in such a manner to turn and/or move the vessel so as to restore the various values to the desired values and hence the error signals to zero and at the same time the timing and the rate of vessel move-up along the route is controlled by controlling the timing and rate at which the pipe is allowed to be payed out or reeled in. The vessel positioning means may consist of a number of rotatable thrust units suitably arranged either with or without conventional propulsion units or a plurality of anchors arranged around the vessel with controllable winches.
