Patent FR-2570186-A1 (FR)
Title: Method and device for measuring the degree of polarisation
Inventor: BOISROBERT CHRISTIAN
IPC: G01J4/00
Filed: 1984-09-07
Abstract: The linear polarisation of an incident beam is determined by splitting this beam into at least three parts which convey approximately equal amounts of light energy. Each part is directed onto a detector 20 through a fixed polarisation analyser 18. The analysers have different polarisation directions, for example at 60 DEG to each other. A computation instrument 32 allows the degree of polarisation to be determined from the measurements supplied by the detectors. The measurement of the degree of polarisation is in particular usable to determine the threshold current of a laser diode 10.

Abstract: A cotyloidal component for a non-cemented hip prosthesis comprises a hemispherical titanium dome member and a cup of polymer material which is engaged therein to form a friction lining and to receive the spherical head of a femoral component. The titanium dome member comprises a first zone in the form of a portion of a sphere which is angularly displaced with respect to the dome member to be tangential to the equatorial edge and to bear against the roof part of the acetabulum. Disposed in projecting relationship in the zone are two stud portions for the passage therethrough of screws provided to engage into the roof part of the acetabulum and form a primary anchoring means. The zone is covered with a covering of porous titanium capable of being invaded by growing spongy bone to form a secondary anchoring. The second zone is smooth and comprises slots along meridians of the dome member to afford a capacity for elastic deformation comparable to that of the acetabulum in the region of the horns thereof.

Title: Infrared electrical heating consisting of a resistor shrouded in a sleeve
IPC: H05B3/00
Filed: 1985-10-25
Abstract: The electrical apparatus for infrared heating according to the invention consists of at least one static resistor 7, 9 shrouded in a metal sleeve 2 and of a tube 1 surrounding the sleeve 2 with a clearance such that this sleeve can move inside the tube noiselessly when the latter expands - tube, sleeve and resistor constituting a heating unit. In this apparatus, the tube is heated by the sleeve and its outer surface emits infrared radiation. This apparatus is regulated by regulating means which deliver current pulses into the heating units, simultaneously or one after the other. It enables the power to be shed as a function of temperature, through threshold of a third party, thus enabling the emission spectra to be adapted as a function of the application, thus adapting the power and the temperature of the heating element.
