Abstract: The invention relates to a medical device in the form of a cartridge (2) incorporating an assembly permitting the preservation of corneal tissue that has been obtained beforehand by sampling, the device comprising: a storage compartment (24) containing a preserving fluid, at least one input terminal (21) upstream from the storage compartment (24), for injecting a compressed pressurizing gas, at least one control terminal (22) upstream from the storage compartment (24), for injecting a compressed control gas, a pneumatically controlled switching system (26) downstream from the terminals (21, 22), said switching system (26) being controlled by the compressed control gas in order to permit or prohibit the circulation of the compressed pressurizing gas towards the storage compartment (24).

Abstract: The invention relates to a medical device for preservation of corneal tissue (3) that has been obtained beforehand by sampling, the device comprising a base (11), at least one side wall (12), and means for receiving and blocking the corneal tissue (3), characterized in that the device additionally comprises an applanation lid (13) for covering an opening of the device opposite the transparent base (11), the applanation lid (13) comprising: a transparent window (131), and a support (132) between the window (131) and the side wall (12), the support (132) comprising means for moving the window (131) in translation with respect to the side wall (12) of the device.

Abstract: The invention concerns a method whereby an optical signal representing the amount of ionizing light of at least a gas in the proximity of an object is displayed and/or recorded. Said method is characterized in that it consists in: gradually increasing (D1) the voltage (U) between the object and the conductor element up to a final value (U2) wherein the maximum brightness (L1) is observed; determining, as first characteristic value of the object, the value of the voltage (U2) as from which the brightness (L2) is not less than about 10% of the maximum brightness (L1) and in determining, as second characteristic value of the object, the voltage value as from which the brightness (L3) of the signal is not less than about 90% of the maximum brightness (L1). The installation comprises a sensor equipped with a flexible membrane defining a volume of confinement for a gas or a gas mixture wherein the ionization occurs.

Abstract: A hook selection device for a weaving loom dobby head where the dobby includes a bottom board carrying hooks and an upper part for supporting the selection device. The upper part moves relative to the bottom board and includes rigid heald shafts provided with a catch corresponding to each hook on the bottom board. The position of each catch relative to a corresponding hook being controlled by an electromagnetic device having a coil. Each rigid heald shaft has a portion made of magnetic material and is mounted on the upper part so as to pivot about a pin. The selection device creates a permanent magnetic field in a region of the selection device having the heald shaft. The coil and permanent magnetic field drive the heald shaft to pivot either into a first position to permit entrainment of a catch and corresponding hook and a second position which does not permit entrainment.
