Abstract: A vehicle capable of being converted between a flying condition and an automotive riding condition. The vehicle has a telescopically extendable tail having a first tubular tail segment and a second tail segment disposed axially slideable within the first tubular tail segment. The tail is provided with at least two form-closing coupling members located at an axial distance from each other for providing a force-transferring coupling between the second tail segment and the first tubular tail segment in the extended state of the second tail segment, each of the form-closing coupling members capable of transferring torque and transverse forces, and each of the form-closing coupling members coming into engagement by axial displacement of the second tail segment in the outward direction.

Abstract: The present invention discloses a vehicle (1) capable of being converted between a flying condition and an automotive riding condition. The vehicle has a telescopically extendable tail (10) comprising a first tubular tail segment (11) and a second tail segment (12) disposed axially slideable within the first tubular tail segment. The tail is provided with at least two form-closing coupling members (21, 35; 31, 36) located at an axial distance (LI) from each other for providing a force-transferring coupling between the second tail segment (12) and the first tubular tail segment (11) in the extended state of the second tail segment (12), each of said form-closing coupling members (21, 35; 31, 36) capable of transferring torque and transverse forces, and each of said form-closing coupling members (21, 35; 31, 36) coming into engagement by axial displacement of the second tail segment (12) in the outward direction.

Abstract: A device for connecting cryogenic fluid containers includes a connection having screw-threaded connection portions and a flange having at least one pair of openings spaced by a predetermined distance. The device also includes a retaining strap of L shape with two wings cut out in U shape, the front wing also having a pair of openings spaced by the same distance as the openings of the flange. Rivets secure the strap and the flange to each other. The front wing also has a marking identifying the gas corresponding to the distance between openings.

Abstract: The connection (5) comprises, between its screw-threaded connection portions, a stay (9) comprising at least one pair of openings (10) spaced by a predetermined distance and serving for the securement to each other, by rivets (19), of a retaining strap (11) of L shape with two wings cut out in U shape, the front wing (12) also having a pair of openings spaced by the same distance as the openings of the stay (9), as well as a marking identifying the gas corresponding to said spacing. Use in containers for cryogenic fluids.

Abstract: Quantities of liquid are distributed via a conduit (5) connected to a source (4) of the liquid, by periodically opening and closing a closure member (7) disposed in the conduit, and injecting, during a predetermined period, immediately after the 5 closing of the closure member (7), a quantity of gas into the conduit portion (6)immediately downstream of the closure member. The duration of the cycle between two successive openings of the closure member (7)is less than 0.1 second. The liquid is an inert liquefied gas, e.g. nitrogen or argon. The injected gas is the same as the liquefied gas and comes from a same cryogenic receptacle (1). The invention is useful for rendering inert or pressurizing containers of food products.

Abstract: A canister for specimen holders, includes a receptacle (1) having an upper opening (50) and a rod (3) for supporting the receptacle. A cover (5), supported on a support (8) mounted on the rod (3), is displaceable between a first position, over the opening (50) and a second position freeing the opening. The support (8) is mounted by hooking (10, 11) on the rod (3). A manually releasable lock (18) releasably locks the cover (5) in its first position. The cover (5) is pivotally mounted on the support (8) about a pivot (14) whose axis is parallel to the rod (3).

Abstract: The container includes a shell defining an interior volume and including a main part, peripherally bound by a portion of a main partition and an end part defining a duct giving access to the interior volume, the transverse dimensions of the duct being smaller than those of the main part and being closable by a shutter, and a level detector typically of the capacitive type, permanently disposed in the shell on at least one zone of the portion of the main partition, and connected to an outside box for the treatment of a signal of the detector. Application for example to cryogenic containers.

Abstract: The holding container comprises an inner casing and an outer casing of the same or different materials and a cryogenic liquid withdrawing pipe including an inner portion having a section advantageously in the form of adjacent spiral turns, which is kept in resilient contact, typically by means of a spring spacer against the inner face of the other casing, thus enabling to provide heat exchange contact between the section of the first part of the pipe and the outer casing notwithstanding the nature of the materials constituting the pipe and the outer casing. Application for example to self-pressurizable holding containers.
