An anti-balloon device (14) constituted by a continuous shield (15-24-115) which is rigidly coupled to the body (16) of the feeder and has at least one detachable portion (15b-26-126-126') which, once removed from its active position, allows access to a corresponding and underlying portion of the feeder and/or to the yarn (F) that unwinds from the feeder.

A fuel tank mount for forklift trucks is adapted to hold a fuel tank over the top of a counterweight in a manner that the tank may be easily lifted up and lowered down. The fuel tank mount includes a swing arm replaceably carrying the fuel tank and mounted to the counterweight for swinging movement about a tilted pivot axis between a home position wherein the fuel tank is held over and laterally a...

The invention concerns composite polyester films with good barrier properties relative to gases. More precisely, it concerns a biaxially drawn film, based on polyester and having improved barrier properties relative to gases, characterised in that it comprises a base polyester film of 5 to 50 mum, coated on one of its two surfaces with a deposit containing polyvinyl alcohol and a water dispersible...

The invention concerns an equipment comprising boots (6), skis (1) and fixing elements (2) each designed to be integrated with one boot (6) and its associated ski (1) and to cause them to be separated in the event of a situation which can lead to the skier wearing the equipment to be injured. The invention is characterised in that it further comprises in each boot: first means (9) maintaining the ...

A bullet-proof window pane construction for a safety vehicle is composed of three laminated window panes 5,7,9 which are spaced apart from one another forming two fluid or gas filled gaps. At least one laminated window pane 7 is positioned obliquely relative to the adjacent panes 5,9 having the effect as to deflect the path of a projectile 4 within the window. The laminated panes are formed from a...

The drilling tool (14) is mounted on a rotating vertical shaft (16), a series of tubular sections (18) connected end for end, further sections being added at the well-head (20) as work progresses.Electrically conducting drilling mud fills the tube interiors (24) and the annular space (26) between the shaft and the wall (10) of the borehole. To prevent direct electrical connection between inner and...

The ground drill uses the support cables as a transmission to convey information to the drill head. The transmission is for information to and from a drilling head suspended to drill into the ground. The head is suspended by supports (210) which are at least partially electrically conducting. A first electro magnet (220) is mounted near to the drilling head to transmit or receive a current which f...

Cet agencement est constitué d'un support d'un circuit électronique (6), d'un boîtier (1, 2; 5) entourant le support et de conducteurs électriques (13) servant à connecter électriquement le circuit à des moyens électriques périphériques prévus à l'extérieur du boîtier, lequel est constitué d'un élément de fond (5) maintenant le support de circuit avec le circuit et d'un couvercle de boîtier (1,...

The prosthesis consists of femoral and tibial components, with a meniscal element (20) between them which has upper and lower surfaces which complement the corresponding thrust surfaces of the femoral and tibial components. The lower thrust face (23) of the meniscal element has a concave spherical surface, while the upper face of the tibial component has a convex spherical surface which is congrue...

The spinal cage implant (1) comprises a central part (3c) with walls (4) and terminal parts (5,6) for bearing against the cortical bone of the vertebral end plates. The central part is adapted to penetrate the vertebral end plates and transversely projects from the terminal bearing parts. Implant bears against the vertebral end plates with terminal parts and contains bone graft material between w...

An open-porous metallic tissue replacement and/or support prosthesis, especially for cervico-maxillo-facial implantation especially as a larynx reconstruction prosthesis, is formed by consolidation of titanium (alloy) or other biocompatible alloy microspheres having dimensional and surface characteristics ensuring cellular colonisation at a more rapid rate than any bacterial colonisation, after in...

The device is an annular structure that is installed on a specially shaped wheel rim within the tyre. The structure comprises two flat rings of flexible material separated by a set of radial spokes the full axial width of the rings. The inner ring holds tight against the rim and the outer ring diameter is chosen to push against the tyre surface when the tyre deflates. There are variations in eithe...

An ultrasound image is obtained by subjecting an object containing an ultrasound contrast enhancement agent to a first imaging pulse burst and then to a second release pulse and then to a second imaging pulse to obtain two images and then comparing the two images to obtain an enhanced image.

The invention relates to acid-labile and enzymatically divisible compounds for in-vivo and in-vitro diagnosis by means of near infrared radiation (NIR-radiation), the use of said compounds as optic diagnostic and therapeutic agents, and the diagnostic agents containing said compounds.

Apperatus to produce the tubes, for lost mould shaping of concrete, winds spiral coils of strips with a complex structure. The strip material has at least one outer layer, impermeable to water, of a thermoplastic material which can be fused to adjacent layers at a suitable temperature, through heat that softens the plastics for fusion bonding. The heater has a temperature control, with heat measu...

The reel winder is composed of two cardboard plates located either side of an axial tubular sheath (5). The two plates are made from the same rectangular blank (A) and comprises a flap (B) whose free edge has several folding lines (4), enabling the tubular sheath to be formed. A second flap (C) has in its central part an adhesive strip (7) for fixing the sheath. Folding of a third flap (D) comple...
