Definitions

  • the present invention relates to a method and an apparatus for collecting and dispersing ferromag ⁇ netic particles in a fluid medium.
  • US-3,985,649 discloses a process for separating a substance from a liquid in a container utilising magnetic forces.
  • the substance is formed of ferromag ⁇ netic particles which are actuated, for the said sepa ⁇ ration, by means of an electromagnet immersed in the liquid.
  • the ferromagnetic particles may have been formed of a ferromagnetic core and a reaction product bonded thereto, optionally via a coating, and formed of a first reactant bonded to the core or the coating prior to the introduction of the cores into the liquid, and a second reactant within the liquid.
  • the electro ⁇ magnet is energised and then attracts the particles and can be removed from the liquid and the container together with the particles.
  • the ferromagnetic particles thus removed from the liquid and the reaction product which may be bonded thereto, can be subjected to further processing steps in other liquids, in which case the electromagnet may be deenergised.
  • the electrical lead-ins of the elec- tromagnet constitute an obstacle to easy and convenient handling of the magnet.
  • the thin-walled, nose-shaped end of the plastic sleeve which is permeable in respect of magnetism but free of remanence, causes the ferromagnetic par- tides to collect around this end when the permanent magnet is inserted therein, the shoulder interconnect ⁇ ing the nose and the relatively thick jacket wall preventing said particles from following, on the outer side of said jacket wall, the movement of the magnet when displaced from the nose in order to disperse the particles.
  • the sleeve preferably is an inexpensive mass- produced single-service plastic product for collect ⁇ ing and dispersing the ferromagnetic particles.
  • the invention will now be described in more detail, reference being had to the accompanying drawing illu ⁇ strating an uncomplicated basic embodiment of an appa ⁇ ratus for carrying the method according to the inven ⁇ tion into effect.
  • a test tube 1 contains a liquid 2 with ferromagnetic particles 3.
  • An apparatus accord ⁇ ing to the invention, or a probe, for collecting and dispersing these particles is designated 4. It com ⁇ prises a cylindrical, for example injection-moulded plastic sleeve 5 having a closed nose-shaped end 6.
  • the sleeve 5 has a passageway 7 which is of uniform width and extends from the open end 8 of the sleeve into the nose 6.
  • the nose 6 thus has a thinner jacket wall than the body 9 of the sleeve, and also a thin end wall.
  • the passageway 7 accommodates a permanent magnet 10 for reciprocal movement within the passage ⁇ way 7 in the longitudinal direction thereof by means of a shank 11 attached to said magnet in some suitable manner and extending through the open end 8.
  • a coiled spring 12 may be positioned between a flange 13 on the shank and a flange 14 on the sleeve.
  • the plastic material for the sleeve is so select ⁇ ed that it is permeable to the magnetic field of the magnet 10 at the thin nose wall, but less permeable to this field via the thicker body wall 9.
  • the plastic material has minimum residual magnetism (remanence), if any at all.
  • the magnet 10 When the probe 4 is inserted in the tube 1 and the magnet 10 is moved into the nose 6, the spring 12 being compressed between the flanges 13 and 14 which are held between the fingers of one hand, the ferromagnetic particles 3 will collect on and adhere to the nose.
  • the magnet When the magnet is moved in the opposite direction, which may be achieved by easing the finger pressure on the flange 13, the particles 3 are released from the sleeve 5. They cannot accompany the magnet 10 in its upward movement because of the shoulder between the nose 6 and the jacket wall 9 of the body.
  • magnetic particles 3 to which adheres a reactant/reaction product/absorbent/adsorbent or the like originating in the liquid 2 are transferred to another test tube containing another liquid for reaction or further treatment therein, after dispersion in said other liquid.
  • the construction described above is a basic one. It may be made more sophisticated in a manner obvious to those skilled in the art by providing, for example, means for locking the magnet 10 in the collecting position and the releasing/dispersing position, for example by means of a mechanism resembling the mechanism of a ballpoint pen for locking the retracted and ex ⁇ tended positions of a spring-loaded ink cartridge.
  • a person skilled in the art will have no difficulty in devising a mechanism to provide for rotatability of the sleeve 5 about the shank 11 and the magnet 10 by the same hand which effects longitudinal movement of the magnet 10. Such rotation may be accomplished by means of a rack and gear mechanism, a clock-winding spring, etc.
  • the advantage of having a rotatable sleeve 5, especially if the sleeve is provided with wings, is that the liquid and the ferromagnetic particles there ⁇ in can be agitated, possibly after they have been released by the sleeve 5.

Abstract

Un procédé et un appareil, servant à recueillir et à disperser des particules ferromagnétiques dans un milieu gazeux ou liquide, utilise un aimant qui est introduit dans ledit milieu. Un manchon (5), constitué en un matériau plastique perméable au champ magnétique mais sans rémanence et ayant une extrémité de bec (6) à paroi mince et une enveloppe à paroi mince, est également utilisé. Un corps d'aimant permanent (10) qui, une fois fixé à des moyens d'actionnement (11, 13), peut être déplacé à l'intérieur dudit passage dans sa direction longitudinale à l'aide desdits moyens d'actionnement à partir de l'extrémité de manchon ouverte, est monté dans le passage (7) du manchon. Lorsqu'il s'agit de recueillir les particules ferromagnétiques (3), ledit aimant permanent est déplacé à l'aide desdits moyens d'actionnement dans l'extrémité de bec fermé et, lorsqu'il s'agit de disperser lesdites particules, ledit aimant permanent est déplacé dans une position espacée du bec.
