Title: Improved method of and apparatus for obtaining continuous countercurrent contact between solid particles and a liquid
IPC: B01J47/10
Filed: 1954-10-22
Abstract: 770,110. Purifying liquids; treating waste effluents. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANISATION. Oct. 22, 1954 [Oct. 22, 1953], No. 30527/54. Classes 46 and 111. [Also in Groups II and VI] Continuous countercurrent contact between solid particles and liquid is obtained by feeding solid particles to one end of a contacting apparatus 1 from hopper 17 and feeding liquid at the opposite end of the apparatus through pipe 16, passing the solid along a series of perforated plates 2 arranged at substantially the same level or offset from each other, and pulsating the liquid by diaphragms 5 so that, at each pulsation, the liquid passes through the perforations and returns, causing an intermittent partial fluidizing of the bed of particles on the plate. The magnitude of the pulsations and the overall liquid flow velocity through the apparatus are controlled to give the desired contact time in the apparatus. The apparatus is divided longitudinally into a number of compartments by baffles 7 and 8 forming a labyrinth through which the particles pass from one compartment to the next, being withdrawn from sump 18, adjacent the last compartment, by air lift 19. Flow of liquid through the labyrinth, against the direction of flow of solids, may be reduced by arranging a series of partitions offset from the baffles 7 and extending downwardly from above the liquid level to below the edges of baffles 7, or by reducing the porosity of the plates 2 in the region of ballles 7. At each pulsation liquid overflows into pipes 13 in each compartment and passes through non-return valves 15 to adjacent compartments in the opposite direction of the flow of solids. The treatment of particles heavier than the liquid or lighter than the liquid is catered for by arranging the screen below or above the bed of particles respectively. The apparatus may be used in a continuous ionexchange process for recovery of metal from a dilute solution, the metal-loaded resin particles being stripped of metal in a second contacting device, washed and recycled. Thus copper may be removed from the effluent of a brass plating mill and recovered as concentrated copper sulphate solution. A further application is the removal of undesirable ions from a water supply to render it suitable for boiler feed, or for laundry, domestic or chemical industrial use.

[Class 52 (iii)] A tripod head for supporting a camera or the like in which a universal ball-joint affording adjustment or traversing motion by a radial handle 7 extending from the joint is characterised in that the joint is locked or unlocked to prevent or permit movement or adjustment of the camera by means of a hand pressed lever 8 fitted in a pistol grip portion 7a formed on the handle, said lever being adapted to engage a push rod 6 located in the handle and connected to a shoe 5 housed in a recess formed in the ball-joint housing 1 and engaging the ball. The manual operation of the lever 8 which causes tangential displacement of the shoe with respect to the ball may be with or against the pressure of a spring housed in the pistol grip. Alternatively the spring may be housed in the radial handle and may act on the push rod or shoe directly. In further modifications the lever 8 may be disposed of and the push rod extended to project beyond the handle to be thumb pressed against suitable spring means to operate the joint. The camera is mounted on a knurled screw itself mounted in the upper part of the ball joint housing and the tripod legs are attached to an extension formed on the ball. The pistol grip may be suitably recessed to house a spirit level and fitted with a releasable support for shutter actuating means on the camera.

Abstract: 741,854. X-ray apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 5, 1953 [Nov. 8, 1952], No. 30616/53. Class 98 (1). Apparatus for X-ray spectrometry of the kind in which material the composition of which is to be estimated is irradiated with primary X-rays, and part of the secondary radiation emitted by the material impinges on a thin plate of crystalline material having a cylindrical surface and rotatable about an axis which coincides with a generatrix of the surface, a convergent beam of secondary radiation reflected by the plate being measured by means of a detector which is located in the neighbourhood of the minimum cross-section of the beam, is characterized in that the shaft 17 which carries the plate 7 of crystalline material is integral with a crank 16, a link 15 the free end of which positions the detector 10, is pivoted on the end of crank 16 remote from shaft 17, and means are provided for rotating the link 15 about its pivot at twice the angular speed of the crystal 7. As shown in Fig. 3, the material 1 is irradiated by means of an X-ray tube 3, and the secondary rays fall, in part, on the curved crystal plate 7, the lattice planes of which are perpendicular to its surface. The shaft 17 is driven by a worm 21 and worm-wheel 22. Arms 15, pivoted to arms 16 fixed to shaft 17, are fast with a gearwheel 19 meshing with a gear-wheel 20 of twice its diameter fast with shaft 17, so that arms 15 move about their pivot with twice the angular speed of arms 16. A shaft 28, journalled in arms 15, carries the radiation detector 10 and beam-limiting diaphragms 23, 24. A slotted strip 27 engaging shaft 17 keeps the detector directed towards the crystal 7. The gears 19, 20 may be replaced by pulleys connected by a belt drive. To increase the accuracy of the positioning of crystal 7, the diameter of gear 19 may be reduced with respect to gear 20; in this case gear 20 is rotated in a direction opposite to the direction of rotation of the crystal. U.S.A. Specification 2,540,821 is referred to.

Title: Improvements in rotary fluid meters
IPC: G01F1/05
Filed: 1931-11-05
Abstract: 391,831. Rotary meters. BARON, H., 231, Strand, London.-(Siemens & Halske Akt. - Ges. ; Siemensstadt, Berlin.) Nov. 5, 1931, No. 30696. [Class 110 (ii).] A rotating reaction meter c is supplied with liquid by a tank a through a pipe b. A second pipe l connects the space above the liquid in tank a with the space in the drum i above the liquid being metered; until the rising level of the latter seals the lower end of pipe l. Further rise in the level causes liquid to pass up the pipe l due to pressure in the drum i and adjusts the quantity of gas trapped in the drum and also acts as a vent for gases liberated from the liquid in the meter. The pressure of the gas above the surface of the liquid in drum a may be above, below or at atmospheric pressure. The pressure in the drum i exceeds that in drum a by the pressure due to the column of liquid in pipe b. Several pipes b and l may be provided. The top end of pipe l may terminate in the atmosphere or through a valve which permits the passage of gas at definite pressure but prevents liquid from passing. The casing g may be supplied with gas at a pressure greater than that of the stopping gas in the drum i. The stopping gas may be replaced by a liquid of specific gravity exceeding that of the liquid being metered. In this case the position of the meter is reversed. In a modification the collector chamber d is merged into the bottom of casing g. The meter construction is described in Specification 391,832.

Abstract: 897,186. Inking-apparatus. LINOTYPE & MACHINERY Ltd. Sept. 2, 1960[Sept.9, 1959], No. 30748/59. Class 100(2) Control mechanism for varying the feed of ink from an ink fountain to an ink roller comprises a plurality of adjusting screws positioned transversely of the ink fountain for axial adjustment to flex the free edge of the ink blade relatively to the ink fountain roller, a ratchet and pawl device associated with each screw for rotation of the screw selectively to advance or retract the screw, a transverse series of latches, of which one latch is associated with each ratchet and pawl device, and means for selectively moving each latch to an operative position for the transmission of reciprocatory motion to the associated ratchet and pawl device to effect adjustment of the screws. The blade 1, Fig. 1, is adjusted by means of a plurality of blocks 7, each carried by a screw 6 to which is pinned two ratchet wheels 9, 10 having oppositely disposed teeth. Pivoted at 13 to a series of forks 114, Figs. 1 and 2, are a series of pairs of levers 11, 12 carrying pawls 111, 112 urged by springs 18 into engagement with the wheels 9, 10 respectively, but prevented from such engagement by pins 22, 23 on a cross slide 19. The cross slide is movable by the energization of one of two solenoids to allow either the engagement of all the pawls 111 with the wheels 9 or of all the pawls 112 with the wheels 10. The forks 114 have each a shank 14 slidable vertically in a fixed cross bar 16 and urged downwardly by a spring 17. The shaft 47 controlling the movement of the ductor roller imparts vertical oscillating movement through linkage 46, 45, 44, 40, 36, 35 to an elongated carrier 30 pivoted to a shaft 31. Corresponding to each fork 114, the carrier supports a solenoid 33, the armature 132 of which is secured to a latch 32, so that energization of a solenoid 33 projects a latch 32 to engage beneath a fork 114 and impart thereto the vertical movement of the carrier 30, thus rotating the corresponding selected screw 6 in a direction predetermined by the position of the slide 19. The wheels 9, 10 may have teeth arranged so that they are rotated on either the upward or return strokes of the pawls. The screws can be rotated manually by knobs 49. The blade and control assembly can be swung about a rod 5 clear of the fountain roller 2.
