IPC: B01J13/22

Abstract: 1,257,178. Multiple walled microcapsules. PILOT MAN-NEN-HITSU K.K. 24 Dec., 1968 [28 Dec., 1967], No. 61355/68. Heading B8C. Microcapsules having walls comprising two or more layers of polymeric material are made by forming a primary encapsulating layer around droplets of a liquid dispersed in an immiscible liquid continuous phase and thereafter causing a reaction to occur between a substance dissolved in the encapsulated liquid and another which is present or which has subsequently been introduced into the continuous phase to produce a polymer which forms an additional encapsulating layer either outside, inside or integral with the primary encapsulating layer, the reaction occurring when one or the other of the solutions permeates the primary layer and contacts the other. If more than one reactive component is present in the encapsulated liquid, the procedure may be repeated to produce capsules having three, four or more layers of encapsulating material. The primary layer may be formed by any convenient method such as conservation (especially for a gelatine or gelatine/gum arabic layer), liquid/liquid phase separation of a polymer from the continuous phase, polymerization and deposition of an insoluble polymer from a monomer contained in either phase or by condensation of reactants contained in both phases. The succeding layers may be produced by reaction between any one of a number of pairs of reactants, one reactant of each pair being soluble in a hydrophilic liquid and the other in a hydrophobic liquid. Many such pairs are specified these in general being substances which react to form polyamides, polyesters, polyurethanes, polyethers, epoxy resins and the like, e.g. polyisocyanates and polyols, polyisocyanates and polyamines; polyacyl compounds and polyamines, alkali salts of glycols or phenol/formaldehyde condensates; polyepoxy compounds or epoxy-halogeno compounds and polyamines; compounds having acyl chloride or sulphenyl chloride groups with polyols (including cellulose derivatives) or compounds having amino and/or carboxyl groups (e.g. gelatine or casein); aldehydic compounds and polyols-; methylol modified urea and melamine resins and inorganic acids and acyl chloride or sulphenyl chloride-containing compounds and compounds housing alkali salts of methylol groups. Examples relate to capsules containing ammonium sulphate solution, cosin solution and dyes.

Abstract: 1,257,534. Heating liquids by contact with gases. GAS COUNCIL. 19 Nov., 1970 [24 Nov., 1969], No. 57406/69. Heading F4K. Tank liquid 2, which may be water, is heated by circulating it upwardly through an annular passage 16 wherein it directly contacts upwardly flowing combustion gases exiting through openings 9 from the lower end of a cylindrical combustion chamber 3. An outlet duct 11 extending radially outwardly from the upper end of the passage 16 leads into a flue 12 containing a forced draught ejector 13 arranged to apply suction to the passage 16 and cause the level of liquid therein to rise. The combustion gases separate out and are vented through the flue 12 while the heated liquid returns to the tank 1 through a return duct 15. A gas burner 5 located at the upper end of combustion chamber 3 is supplied with a gas/air mixture through a pipe 6, the mixture being ignited by spark plug 7. In an alternative arrangement (see Fig. 2, not shown) the return duct (21) concentrically surrounds both the combustion chamber (3) and the annular passage (18) wherein the liquid contacts the combustion gases. A pump or fan may be used in place of the ejector (24).

Abstract: 1,266,617. Boring earth. C. C. BROWN. 25 Nov., 1969 [25 Nov., 1968], No. 57706/69. Heading E1F. A method of drilling a well comprises inserting a bit assembly through a string of casing C and securing the assembly to the lower end of the casing, and rotating the casing and radially extending, cutters 45 of the assembly to drill the bore-hole. At the bottom of the casing is a housing 10 having recesses 15 to receive dogs on the bit assembly when a sleeve 20 is released from shear pins by a jar, a spring 25 urging the sleeve into a position to press the dogs outwarding. Pins 18 on the housing engage grooves 16 on the assembly to position the assembly correctly. Application of drilling fluid pressure causes piston 35 to move downwardly to extend cutters 45 either by means of rack 50 and pinions 49 or by a crank pin and lever arrangement (Figs. 14-16 not shown). The bit also includes fixed cutters 40 and 41. The bit assembly can be removed by a fishing tool pulling sleeve 20 upwardly to release dogs 14. The casing is rotated by a mandrel extending into the top of the casing and having slips movable radially to grip the casing by relative rotation between the mandrel and a wedge-shaped expander. Semi-circular shoes are mounted on the expander and on rotation of the expander are caused to grip the casing and thus to rotate it. The mandrel is rotated by a fluid pressure powerunit.

Abstract: 1,266,854. Air cushion vehicles. NATIONAL RESEARCH DEVELOPMENT CORP. 17 March, 1969 [15 March, 1968], No. 12716/68. Heading B7K. A gas cushion vehicle has at least one substantially vertically disposed fin 15a mounted on the vehicle for rotation under the action of wind forces about a substantially vertical axis 18, and means 16a automatically to adjust the incidence of the fin with respect to the relative wind direction, whereby to render the vehicle substantially neutrally stable for a majority of relative wind directions. Tab 16a is hinged to fin 15a at 17, and carries a follower 20 which co-operates with a cam 19, so that as fin 15a is rotated by a relative wind the incidence of tab 16a with respect to fin 15a changes, causing fin 15a to come to rest at an angle to the relative wind. A yawing moment is thus generated by the fin on the vehicle which, with a suitable cam profile, opposes the yawing moments generated by the wind on the remainder of the vehicle. To ensure that there is always a moment about the vehicle centre of gravity for all relative wind directions, at least two spaced fins 15a are required. Fig. 9 shows an arrangement which provides positive stability, that is allows a heading to be maintained relative to the wind direction; a first tab 16a maintains the vehicle neutrally stable as above, while a second tab 16b is controlled by a frusto-conical cam 19b initially centred on shaft 18. Cam 19b is moved horizontally to move tab 16b, and then vertically to restore the tab to its initial position; since cam 19b is then not centred on shaft 18 any change in fin position moves tab 16b to maintain the vehicle heading relative to the wind. In a further embodiment, Figs. 13 and 14 (not shown), hydraulic jacks (30), (35) are used to move a cam (19) both vertically and horizontally to assist manoeuvering the vehicle, the cam also having a profile which renders the vehicle neutrally stable to relative winds. The tabs used may be replaced by jet flaps or boundary layer control arrangements, and these aerodynamic control means could be governed by any mechanism for sensing relative wind directions. The fins are preferably situated clear of any slipstream from the main propulsion system of the vehicle.
