Title: Illuminated road warning sign - has optical fibres taking light from source to lenses on display panel
Inventor: LOOTEN FRANCIS
IPC: G02B6/36
Filed: 1981-01-30
Abstract: The illuminated road sign comprises a panel on which the warning, and the triangular outline are highlighted in small lenses. Each lens is situated at the end of an optical fibre supplying it with light. The optical fibres are gathered into a bundle and are taken down to the source of light. The lenses defining the outside frame of the sign may be of a different size to those of the warning symbol itself, so that the parts of the sign may show up with different intensities. Some of the optical fibres may be coloured in order to produce different colours on the sign itself. The lenses may be glued into the panel, and the ends of the optical fibres may also be glued into place.

Title: Aircraft tyre sub-tread reinforcement with extensible borders - to sustain local tensile stress and suppress dynamic delamination stresses at high speeds
Inventor: MUSY JACQUES
IPC: B60C19/00
Filed: 1981-02-12
Abstract: An aircraft tyre is built with a composite subtread reinforcement system involving at least three superimposed plies each having a cord bias of 0-30 degrees from the circumferential axis, a central portion made of relatively inextensible cords and borders made of relatively extensible cords. The tyre profile, when mounted on a wheel but not inflated has a carcass crown curvature radius of up to 0.2, pref. 0.08-0.15, and a max. sidewall curvature radius of up to 0.25. Used for mfr. of tyres having a carcass crown curvature of up to 0.12, pref. 0.04-0.10, and a max. sidewall curvature ratio of up to 0.14, to satisfy normal aircraft tyre shape standards, since extension of the sub-tread borders by service pressures modifies the shape of the carcass. Deformation of the extensible subtread reinforcement borders allows the carcass crown and sidewall curvatures to be reduced to the required levels whilst establishing a tensile stress in the subtread borders to suppress stable dynamic stress variations at high speed. Suppresses vibrations which can otherwise develop sufficiently to initiate delamination and loss of tread if the subtread reinforcement border stress patterns are low or even compressive.

Patent FR-2494029-A1 (FR)
Inventor: MAYLANDT HELMUT
IPC: H01G4/32
Filed: 1981-10-26
Abstract: An electrical capacitor is proposed which has a winding (24) consisting of metal-coated films, especially plastic films, and is provided with a disconnection device which interrupts at least one electrical supply lead to the winding in the event of excessive heating of the winding. A breakaway conductor (48, 50) is provided in the electrical supply lead (40) as the disconnection device and its ends are anchored at points (52) whose mutual separation is a function of the changing magnitude or shape of the cross-sectional profile of the deforming winding (24). In the case of a preferred embodiment, the anchorage points (52) are provided on a slotted sleeve (42) which is pushed in a fitting manner over the winding (24). Furthermore, the breakaway conductor can preferably be formed by a metal coating (80) which is sprayed onto the slotted sleeve (82, Fig. 5) and has a narrowed (constricted) weak point in the region of the slot (84). This design has the advantage that the disconnection device responds in good time in the event of damage even in the case of those capacitors in which gases formed in the interior of the winding expand the winding radially.

Title: View-finding system for TV camera - includes frame of light cast over photographed scene to enable subjects to realise whether they are within field of view
Inventor: VACHER MICHEL
IPC: H04N7/14
Filed: 1982-06-29
Abstract: The camera accessory includes a mask (12) situated on the front of the body in a plane at right angles to the optical axis of the camera. A light source (13) source (13) comprises LED's and lies behind the mask. The mask then casts a prism-shaped shadow over the scene in front of the camera. The apex of the prism is the light source. Around the area of shadow (14) there is a region of light (17). If a person can see the light, and is therefore outside the shadow region, then he knows that he is not in the field of view of the camera. In alternative arrangements the two sides may be illuminated with different coloured lights. The mask may have notches cut in its vertical sides to help in indicating proximity to the edge of the field of view. The arrangement is esp. intended for video-telephone systems, enabling the fixed camera to produce a satisfactory image of the user.
