Abstract: A surgical clamp is provided for insertion into a clamp driving device. The surgical clamp has two parallel anchoring legs linked by a common rectilinear section (1c) or yoke. The rectilinear section or yoke is suitable for being inserted into the driving device. The rectilinear section or yoke has a flat top, a bottom, and two edges. The two edges merge with the flat top by a generously rounded profile. On the one hand, the two edges merge with the bottom by an inclined flank at an obtuse angle with respect to the vertical plane. At least one of the insides of the legs, the outsides of the legs, and bottom of the yoke is serrated.

Abstract: This invention relates to a surgical clip for cutaneous suture, wherein it successively comprises, starting from the centre of the clip and on each side of the plane of symmetry of the clip, a rectilinear branch, a first bend with concavity facing the skin into which the clip must be engaged, a second intermediate bend with convexity facing the skin and a third bend with concavity facing the skin, this third bend extending by an end leg terminating in the point of the clip and which is inclined by an angle of about 45.degree. with respect to the general direction of extension of the clip. The invention also relates to a tool for applying said clip.

Abstract: An agraffe or staple-shaped element for osteosynthesis intended for fixing the focus of an osteotomy while awaiting consolidation of web from which issue two lateral arms having pointed ends adapted to penetrate in the bone. The web of the agraffe comprises two parts inclined with respect to each other and forming an outwardly open obtuse angle. Each of the lateral arms of the agraffe presents, near its zone of join with the web, fins projecting from the front faces of this arms, such fins reinforcing the anchoring of the agraffe in the zone.

Abstract: An echometer which translates an optical signal into the centimetric or decimetric wave bands. A test signal and the local oscillator signal are provided by a single laser oscillator. The test signal and the local oscillator signal, which are 90.degree. different in phase, are modulated at centimetric or decimetric frequencies, and detected by mixing echo signals and the local oscillator signal with a photodiode or the like.

Abstract: An undersea optical fiber cable with a protective metal casing around the optical fibers 1. The casing includes a stranded assembly 3 of high-tensile metal wires of polygonal cross-section 3A forming an arch structure. The side (4) which is turned towards the axis of the cable is shorter than the outwardly-turned side 5, and intermediate sides 6 touch or interlock. A metal outer tube 7 is formed by skelping a tape to produce a cylinder and then welding the longitudinal edges thereof. The metal casing is filled with a liquid 4A whose density is close to that of water and whose viscosity is close to that of glycerine. The overall density of the cable is slightly higher than that of water.

Abstract: A helical circular wave guide which reduces loss around curves. It includes contiguous turns of copper wire coated with a thermoplastic material, said helical turns being surrounded by a first tube made of aluminium in contact with the helix and by a second tube made of steel held centered in relation to said first tube by supports made of plastic material.

Abstract: A machine for manufacturing circular section helical wave-guides and providing simultaneous calibration of the bore of the helix and snug fitting of the screen around the helix. The helix is loosely fitted in an enveloping tube and both tube and helix are drawn through a reducing die for drawing the tube down onto the helix. The bore of the helix is established by a mandrel and the outer surface of the helix is softened just before entering the die whereby the helix is welded to the inner surface of the tube.

Abstract: A helical wave guide comprising a hollow conductor coated on its outside with an electrically conductive screen and formed by an electrically conductive wire coated with a thermoplastic insulator, wound in a helix and welded turn by turn by surface melting of the thermoplastic insulator. It is applicable to signal transmission.
