Abstract: 1,051,001. Washing granular materials. AMERICAN AGRICULTURAL CHEMICAL CO. May 14, 1965 [June 24, 1964], No. 20521/65. Heading B2H. In, for example, the recovery of phosphate from phosphate and silica bearing ore, a pulp is fed into a body of water and the descending particles subjected to ascending air bubbles, the float particles being removed from the surface of the water and the remaining descending particles subjected to hydraulic size classification. The pulp is reagentized and fed through a pipe 51 into a submerged well 37 where it is acted upon by jets of water through pipes 49 and air bubbles from a pipe 41. The phosphate froth product is floated over a rim 35 of a tank 11 into a launder 33 while the silica product passes through holes 38 around the bottom of the well 37 into the tank 11; any phosphate particles descending with the silica is returned upwardly for discharge into the launder by air bubbles from a pipe 44. The descending silica particles enter a hindered settling column 13 which is established by the action of water fed to the bottom of the column through tangentially-arranged pipes 17 and a perforated restriction plate 18. Only the large or faster-moving particles reach a siphon 23 having discharge pipes 24, 25, the small particles being carried by the upward current of water into a free-settling column 15 for discharge through a siphon 21; the siphon 23 is controlled by a vent 29 having a float-valve 30 which is operated in accordance with the hydraulic pressure in the region of the siphon 23 as monitored by a hydrostatic column 26. Any large phosphate particles discharged by the siphon 23 can be recovered in a subsequent operation. If desired, two apparatus as that described may be employed in series, Fig. 3 (not shown), an anionic reagent being employed in the first stage to float phosphate and a cationic reagent in the second to float silica remaining in the froth product.

Abstract: 1,054,994. Zoom lenses. K. VOCKENHUBER and R. HAUSER. March 9, 1964 [March 8, 1963; May 10, 1963], No.9779/64. Heading G2J. A variable focal length objective is provided with a fixed focus setting by arranging that the full depth of field available is usable at every focal length setting. This is accomplished by automatically moving one of the members during changes of focal length so that one of the two planes defining the depth of field is maintained at a constant distance from the image plane at all focal lengths. As shown, Fig. 3, members 101, 102, are movable during zooming but a small additional movement is superimposed on member 101, such as by shaping the controlling cam somewhat differently from what it would otherwise be, so that at one particular aperture setting, e.g. the maximum aperture, the curves 110, 111, Fig. 5 (not shown), showing the variation with focal lengthf of the limiting planes defining the depth of field are such that one plane, in this case the further plane, curve 110, is at a constant distance from the image plane. By a constant displacement of the front member 101 independently of focal length, the entire depth of field can be displaced towards the objective and curves 113, 114 are obtained. Similarly by another constant displacement curves 116, 117 are obtained. Thus by having detents for the front member a suitable set of curves can be readily provided as the curves overlap so much and thereafter during zooming no separate close-up adjustment is necessary.

Abstract: 1,238,143. Fuel elements. WESTING- HOUSE ELECTRIC CORP. 17 April, 1970 [19 May, 1969], No. 18394/70. Heading G6C. A fuel assembly comprises an array of parallel elongated fuel elements, a plurality of elongate hollow tubular members containing control elements strategically located among the fuel elements and composed of a low neutron capture metal, e.g. Zircaloy, and grid members longitudinally spaced along the tubular members and composed of a metal, e.g. stainless steel, different from that of the tubular members, with retaining members engaging the tubular members at the grid openings, and means formed integrally with the grid, tubular or retaining members co-operating with the other members to retain the tubular members in position in the grid members. As shown in Fig. 6, each intermediate grid member is retained in position by means of two stainless steel sleeves 44a, 44b surrounding each of the tubular members 18 in the openings 32 in the grid structure. The sleeves 44a, 44b are brazed to the grid straps 30. Protrusions 46 in the tubular member 18 engage the sleeves 44a, 44b immediately above and below the sleeves, thereby retaining the grid in position. In another construction (Fig. 7) a tab extension 48 on a grid strap 30 is captured by a spot weld between the Zircaloy tube 18 and a Zircaloy clip 50, the latter being spot-welded to the tube 18 above the tab. The clip 50 is stamped to provide a base which fits through a hole punched in the tab 48, the base being spot-welded to the tube 18. The upper end structure or nozzle (12) of the fuel assembly (Fig. 1, not shown) includes an upstanding flange (17) to which leaf-springs (19) are clamped. The springs co-operate with a coreplate (not shown) to permit expansion of the fuel assembly, but prevent the assembly from being moved upwardly by hydraulic forces. Dowel pins (not shown) extend into diagonally disposed openings (25) in the flange to provide lateral support for the fuel assembly.

Abstract: 1,251,016. Valves. VOITH GETRIEBE K.G. 19 Feb., 1970 [21 Feb., 1969], No. 7986/70. Heading F2V. [Also in Division H1] A solenoid-operated valve has a coil 12 within a magnetic easing 1 having a bore 10 in which slides a magnetic spool/armature unit 2, 3 biased downwards by a spring 23. When the coil is energized to lift the spool magnetic flux lines # pass from the casing into the spool via lands 17, 18. The spool is surface hardened adjacent the control edges 15, 16 and the reduced diameter portion 19 is relatively large so as to have a low resistance to magnetic flux.

Abstract: 1,252,774. Bactericidal compositions. DIVERSEY DEVELOPMENT Ltd. 6 Nov., 1968 [21 Feb., 1968], No. 52517/68. Heading A5E. [Also in Divisions C2 and C3] Bactericidal compositions comprises solutions of a complex obtained by reacting 1 to 9 parts by weight of an alkyl aryl alkyleneoxy alkanol surfactant of formula R'.°.O.(R<SP>2</SP>O) n H, in which R' is a C 5-30  alkyl radical, R<SP>2</SP> is a C 1-4  alklene radical (or mixture of such radicals, n=1-100 and ° is a phenylene radical, with 1 part by weight of bromine. Reaction may take place at 20-200‹F. Examples of surfactants are t-octylphenoxypolyethyleneoxyethanol, linear or branched nonylphenoxypolyethyleneoxyethanol, and dodecylphenoxypolyethyleneoxyethanol. Complexing may be carried out in the presence of 1 part of 37% MCl per 3-100 parts by wt. of surfactant. The compositions are most effective biocides when dissolved in temporarily hard water.

Abstract: 1,257,862. Railway systems. NATIONAL HOSIERY MFRS. FEDERATION, and ELBEO Ltd. 6 Feb., 1970 [8 Jan., 1969], No. 1182/69. Heading B7L. [Also in Division B8] Articles are loaded, stored and unloaded in and from containers 13 mounted on a closed track and travelling when required between a loading station and an unloading station. As shown, as applied to the handling of ladies' stockings, the containers 13 are moved stepby-step along adjacent tracks 16, 17 and 18, 19 and across a transverse track portion 12 at each station, the containers being provided with castors 14 and corner guide rollers 15 so that the containers are always maintained in the same attitude in space. Each transverse track portion 12 comprises a pair of support plates 22, 23, a guide rail 24 and guard rails 25, 26 and each station is provided with a propelling mechanism and a transfer mechanism for the containers. Each container is provided on its underside with diagonally opposite blocks which are acted on by the transfer mechanisms at the loading and unloading stations respectively. Each transfer mechanism comprises a jack-operated slide bar 31, an abutment 32 of which engages the appropriate container block, and each propelling mechanism comprises a double-acting jack 33 which operates a crosshead 35 carrying a pick-up dog 37, engageable with the underside of an adjacent container to push or pull that container. The jacks are controllable at each of the two stations and the arrangement is such that each track is occupied by containers except for one vacant space which is filled by an adjacent container as the containers are stepped along the tracks. Each container is open at two opposed sides and is divided into compartments and sub compartments.
