Patent EP-0233215-A1 (EP)
Inventor: AZZAM RASHEED M A
IPC: G01J4/00
Filed: 1986-06-18
Abstract: Photopolarimètre permettant de mesurer simultanément la totalité des quatre paramètres de Stokes de la lumière. Le faisceau lumineux, dont l'état de polarisation doit être déterminé, frappe, selon des angles obliques d'incidence, les surfaces de trois photodétecteurs (D0, D1, D2) successifs, dont chacun reflète partiellement régulièrement la lumière et génère un signal électrique proportionnel à la fraction du rayonnement qui l'absorbe. Un quatrième photodétecteur (D3) est totalement photoabsorbant et détecte le reste de la lumière. Les quatre signaux de sortie ainsi développés forment un vecteur de signaux I(Boolean not) 4x1 qui présente une relation linéaire, I(Boolean not) = A(Boolean not) S(Boolean not), avec le vecteur de Stokes S(Boolean not). En conséquence S(Boolean not) est obtenu par la formule S(Boolean not) = A(Boolean not)-1 I(Boolean not). La matrice A(Boolean not) 4x4 de l'appareil doit être non singulière, ce qui implique que les plans d'incidence de chacun des faisceaux lumineux soient tous différents. Pour un agencement donné de quatre photodétecteurs, A(Boolean not) peut être soit calculé soit déterminé par étalonnage.

Inventor: SPIES HANS
IPC: G01S17/10
Filed: 1987-08-26
Abstract: An optical range finder with a light transmitter (11) which emits a measuring light pulse, a light receiver (17) which receives the light reflected from the object, an optical reference path (14, 15, 16) and an evaluating unit. The range finder is distinguished by the fact that the reference path exhibits a multiple reflection element (16) which reflects the measuring light beam conducted via the reference path several times in such a manner that the receiver (17) detects a plurality of reference pulses delayed by a transit time through the multiple reflection element, and that the evaluating unit determines the range of the object from the position of light pulse reflected from the object between two reference pulses reflected several times. The range finder thus has the advantage that no internal time base is required since a time base is given by the reference pulses reflected several times.

Abstract: A coherent fire-resisting flexible sheet material for aerospace applications is provided consisting of a layer of ceramic fibres embedded in a silicone rubber compound. The ceramic fibres may be in the form of a plain woven fabric of monofilament fibres of alumino-boro-silicate and the sili­cone rubber compound can be a curable non-foaming methyl-­phenyl silicone compound. In production, the silicone compound is applied to the fabric as a thixotropic paste in sufficient quantity to entirely cover and impregnate the fabric and is forced through the interstices of the fabric by the application of pressure. The coated and impregnated fabric is then placed in an oven to cure the silicone compound.

Title: Soft denture liner.
Inventor: GETTLEMAN LAWRENCE
IPC: A61K6/884
Filed: 1986-12-03
Abstract: The invention provides a denture liner composition for a composite denture based on a phosphonitrilic fluoroelastomer [poly(fluoroalkoxy)phosphazene] curable at atmospheric pressure at temperatures of about 100 DEG  C. or less, conveniently by immersing the packed denture flask in a water bath at the appropriate temperature. The composition includes trimethacrylate and dimethacrylate cross-linking agents for increasing liner hardness and decreasing water sorption characteristics of the cured liner. The composition preferably further includes filler materials for increasing the hardness of the liner product. The composite denture is preferably prepared in a one-step process wherein the liner composition material of a single firmness is cured in situ with the denture base material. Alternatively, a firm liner material is cured at the periphery of the denture, and a softer liner material cured at the center; this provides a firm elastic liner adjustable by grinding where soft tissues must be displaced, and a soft elastic liner over bony anatomy, where stresses from chewing are most concentrated and soft tissues are thin. Another possibility lies in curing the soft liner directly to a precured denture as a reline procedure in an pre-existing denture.

Abstract: The invention is providing a flexibly stiff reinforcing member (14) that will maintain the shape of a pad (12) for absorption of human exudate, such as a feminine hygiene pad, during use. The flexibly stiff reinforcing member will return the pad to its desired shape, even after it has been deformed by movement of the wearer. In a particularly preferred form, the flexibly stiff reinforcing member is a flat strip of polyethylene that extends around the periphery of a feminine hygiene pad. In other embodiments, the resilient reinforcing member may only be present in the periphery of the center or crotch portion of the pad. The strength and flexibility required of the reinforcing member will vary depending on the pad stiffness prior to reinforcing of the pad and the use to which the pad is to be put. The reinforcing element is a flexibly stiff, resilient, substantially nonelastic material. The reinforcing element material may be deformed and then is springy and will return to its shape after deformation.

Abstract: A friction welded part having a sealed flash trap (5) is disclosed, along with a method for producing such parts. The friction welded parts have a hollow cylindrical part (1) and a second part (2) to which the hollow cylindrical part is friction welded. There is an internal flash trap (5) in the region of the weld (4), and the hollow cylindrical part is pinched inwardly or a conical flange (10) is deformed outwardly so as to seal the flash trap from the hollow portion of the hollow cylindrical part remote from the weld. The method involves the conventional steps of rotating the parts with respect to each other under pressure, stopping the rotation, and exerting high pressure to form the weld. Then, the hollow cylindrical part in the region adjacent the flash trap is forced inwardly or a flange is forced outwardly so as to effect the seal. Rolling is the preferred method of forcing the hollow cylindrical part inwardly, and is preferably carried out immediately after the welding, so that the remaining weld heat can be used to advantage. A mandrel or punch is used if a flange on the flash trap is forced outwardly.

Abstract: This invention relates to a technique for forming filament windings which are designed to enable filament (52) to be paid out at a high rate used particularly for guided missile systems using a filament as a data link. Numerous prior art techniques exist which have disadvantages such as difficulty in winding, poor coil stability, and high drag associated with paying out of the filaments. Additionally, some of the prior art techniques do not result in a densely packed coil, thus requiring larger size spools and compromising the packaging efficiency of the overall system. In accordance with this invention, a "deep nested" filament coil winding (80, 94, 102 is provided. By providing a pitch distance of approximately the filament diameter times the square root of 3, and advancing the coils in two equal steps as the turns wrap around the coil spool, a highly densely packed coil is provided which can be wound against a single flange (84, 104) or a pair of separated flanges (84, 86). The winding features excellent mechanical stability and can be wound using conventional winding machines.
