Title: Frein a disque a etrier
IPC: F16D65/095
Filed: 1978-03-15
Abstract: Frein à disque à étrier. Chaque porte-garniture 43 présente, dans une de ses extrémités, un trou 52 de réception d'un axe d'articulation 47 sur lequel il coulisse axialement et, dans son autre extrémité, une fente 55 de réception d'un axe de retenue 57 monté sur le logement d'étrier qui lui permet de glisser axialement sur cet axe 57. Le jeu entre l'axe 57 et la fente 55 est suffisant pour permettre les mouvements circonférentiels dus aux dilatations et contractions subies par le porte-garniture pendant le freinage. Le jeu entre l'axe 47 et le trou 52 est juste suffisant pour que le porte-garniture ne se coince pas sur cet axe, ce qui limite les déplacements circonférentiels du porte-garniture et les charges latérales, génératrices de dommages, qui en résultent. Dispositifs de freinage.

Title: Solar heating window with selective absorbency - has catadioptric surface combining light reflection and refraction
Inventor: DEVIN BERNARD
IPC: F24S23/30
Filed: 1978-03-16
Abstract: The window has a catadioptric surface which combines reflection and refraction to sunlight to produce variable transparency according to light intensity and direction. It can be combined with a solar heating panel to maximise solar energy absorption. A Fresnel lens (26) may be incorporated to focus absorbed energy onto a collector (28) through which a heat-absorbing liquid is pumped (30). The window (40) has an internal surface with prismatic indentations which either reflect or refract light subject to the presence of the heated liquid in the space behind the window. The collector (28) acts as a thermostat and in strong light, the liquid is drained (44) from the window.

Title: Wattmeter and/or voltmeter with numerical indicator - requires instrument which includes processing circuit to give reading in decibels
Inventor: GOUZE PHILIPPE JEAN PAUL MARIE
IPC: G01R15/00
Filed: 1978-04-28
Abstract: The measuring instrument for electrical parameters such as volts or watts has a numerical indication of value. A processing circuit permits an indication of this value in decibels.
