Abstract: A film video player for producing a standard television signal from photographic film includes an image sensor for sensing a film image illuminated by a pulse of light from an electronic strobe light. The electronic strobe light includes a high voltage power supply with a voltage greater than the minimum ignition voltage of a flash tube in the strobe light for igniting an arc in the flash tube, a low voltage power supply having a voltage less than the minimum ignition voltage of the flash tube for producing an extended pulse of light of constant intensity, means including a photocell for sensing the quantity of light produced by the flash tube and including a control device in series with the flash tube for terminating the pulse of light after a predetermined quantity of light is produced, and means for dispersing the light from the flash tube to produce more uniform illumination. The film video player has the advantage of providing a video signal free from visible flicker, of uniform intensity, and constant color balance. A further advantage is that the video player generates very little heat from its electronic strobe light source and therefore requires minimal cooling.

Title: Procede de neutralisation d'acide sulfurique perdu par addition d'un silicate
IPC: C02F1/66
Filed: 1985-06-27
Granted: 1988-10-05
Abstract: Il a été démontré que les silicates de magnésium, surtout l'olivine riche en Mg, conviennent très bien pour neutraliser l'acide sulfurique perdu. Par le présent procédé, on forme un gel de silice et un liquide contenant du Fe/Mg. Les expériences montrent qu'il est possible d'obtenir une séparation nette du gel de silice et du liquide contenant du Fe si le processus de neutralisation se déroule dans une atmosphère inerte. Après la séparation du gel riche en SiO2 il est possible de former par aération un précipité de Fe-V. Le gel de SiO2 peut être bien rincé pour qu'il se forme un produit acceptable qui soit utile, par exemple, dans l'industrie du béton. Les liquides qui se forment sont riches en MgSO4. Ils peuvent être simplement évacués dans l'eau de mer.
