Title: Heat-hardenable synthetic resin reinforcement fabric - contains supplementary heat softenable weft, to avoid fraying when fabric is cut
Inventor: LISSAC PIERRE BERNARD
IPC: D03D15/00
Filed: 1979-08-04
Abstract: A reinforcement fabric for a heat-hardenable resin contains a supplementary weft of a heat-softenable yarn, e.g. of a copolyamide, so that the fabric may be cut easily, without fraying. Fabrics of glass, carbon or 'Kevlar' (RTM), when cut, in order to treat them with resin, or to assemble them into composite materials, tend to fray along the warp yarns on the edge of the cut. Glass fabrics with a greater density of warp yarns than weft are particularly prone to fraying. The incorporation of the heat-softenable yarn, on softening, ensures a binding between the warp and weft yarns. The fabric, when formed of glass, is particularly suited as a reinforcement in the production of skis.

Title: Optical aberration subjective measurement appts. - uses movable prisms to measure focal length of patient's eye
Inventor: REINER JOSEF
IPC: A61B3/028
Filed: 1980-03-10
Abstract: Reflections from the retina can be used to obtain objective measurement of optical aberration, but to obtain accurate figures for binocular vision, subjective tests, with the co-operation of the patient are necessary. This can be done with twin devices each using three lenses, two and a movable prism. Light from a pointer (13) passes through a collimator (14), is reflected at 45 deg. by a mirror (15) and is focussed on a point (F3) inside the prism (6) by a lens (3). The eye observes this image via the other mirror (12) and a lens (4), the axis of which is parallel to that of the other lens (3). The prism is moved backwards and forwards by a screw adjustment (35) until the focal lengths of the two lenses co-incide, i.e. the patient sees a clear image. The setting of the screw is registered on a counter. Astigmatism measurements can be made by rotating the lenses (3 and 4) when they are geared together.
