  • Patent number: 6305585
    Abstract: A filler nozzle for packaging, in particular for use in artificial insemination, has a plastics material body with a male or female conical part that partly surrounds a capillary tube made from stainless steel or a plastics material. The filler nozzle is particularly suitable for filling straws with seminal liquid. It prevents pollution of the closing area of the straw. It is also compatible with automatic placement and with manual handling.

  • Patent number: 6079184
    Abstract: A machine to make up doses of semen in a container comprising welded thermoplastics films that can be opened by hand without using instruments in order to insert therein an insemination probe includes a tubular needle having a nozzle over which is threaded a cleaning ring to prevent coating of a region to be sealed by welding with semen and to keep the walls of the thermoplastics films dry after filling the dose with semen. The sealing weld is made by a device having inverted U-shape jaws. An incision perpendicular to the branches of the U-shape is made at the same level as the latter by an incision device including an orientable blade.

  • Patent number: 6035904
    Abstract: The disclosure concerns an automatic machine for metering and filling, for example volumes of animal semen, in any packaging member, regardless of its diameter and the material from which it is made (straws, glass or plastics material catheters, all types of flask, etc). Essentially intended for artificial insemination of poultry, for example turkeys, this device nevertheless has an extremely wide range of application. For example, using a peristaltic cassette (12) (described, for example, in U.S. Pat. No. 4,702,679 filed by MALBEC), under the control of a digital controller, the machine enables small volumes of liquid to be dispensed with the greatest possible accuracy and very high rates of artificial insemination to be maintained. The objectives of the invention include a device for precise and fast metering of any fluid, primarily for use in animal husbandry and research laboratories.

  • Patent number: 5664399
    Abstract: A device for packaging liquids, particularly animal semen, in pre-scaled and pre-cut pouches provided in a roll and designed for artificial insemination. The device includes a tiltable table with a base enabling adjustment of the tilt angle of the table to facilitate gravitational filling of pouches, a pouch filling station and a sealing station. The device also includes a movable filling needle inserted into a removable needle guide and mounted on a block that includes an inductive proximity sensor for generating an alternating magnetic field which is automatically stopped when a metal liner is inserted into the needle guide following needle insertion into the pouch. Cessation of the alternating magnetic field triggers the sealing of the pouch.

  • Patent number: 5545562
    Abstract: A device for identifying the content of a straw formed of a heat-sealed section of ionomer resin tube offering high performance at cryogenic temperatures comprises a sheath length threaded onto the straw and trapped between the ends of the straw which are flattened and widened in the transverse direction on sealing the straw after filling. The sheath carries printed identifying data and its color facilitates identification. This avoids the possibility of defective printing on the ionomer resin and damage to the straw or its contents by diffusion of constituents of the ink. The sheath can be ovalized at one end to prevent it moving freely.
