Abstract: A module of plant growth medium for use in horticulture (2), comprises a container having at least one wall (4), which defines a reservoir (10) adapted to receive a cutting (22). The reservoir contains a viscous aqueous thixotropic planting fluid (12). The wall of said container comprises a further plant growth medium. The module provides a means for the improved propagation of plant cuttings, such as may result from improved rooting, reduced handling of cuttings and minimal root disturbance when planting on.

Abstract: A glue film (11) on a cellular structure (10) in order to form a regular glue strip on the edges of the partitions of the cells of the cellular structure (10), and the glue film (11) is exposed to a source (24) that emits radiation adapted to reactivity of the glue to only heat the glue selectively. The glue thus creeps without significantly triggering polymerisation. The glue strip is formed on the ends of the partitions without supplying an air flow through the openings of the cellular structure. The portion of the part located below the source is preferably kept approximately horizontal so that the glue strip is formed under the best possible conditions.

Abstract: Suction control device intended to be fitted on an apparatus used in surgery, in particular in ophthalmic microsurgery, said apparatus comprising a handpiece (1) which may or may not be fitted with an ultrasound transducer for fragmenting a body which is to be extracted from the eye, and equipped with an orifice (17) for suctioning debris and connected to a system for pump-activated suctioning of liquid containing debris, characterized in that it includes means (18, 20) which, in the event of at least partial obstruction of the suction orifice (17) of the handpiece (1), are used for maintaining a continuous circulation of liquid between the active end of the handpiece and the pump-activated suctioning system of the apparatus.
