Title: Photographic slide classification drawer - has slide record supports vertically suspended in drawer and retrieved from bottom of drawer
IPC: G03B21/54
Filed: 1977-02-23
Abstract: The drawer system (10) has a rectangular metallic body whose lateral walls support slides. The bottom of the drawer is preferably hinged so that it can be inclined towards the user when the drawer is open. When the photographic slide records contained in the drawer are selected, the designated records fall onto the inclined drawer bottom and thus are fed towards the user who has only to pick them up. An edge at the front of the drawer bottom stops the records from falling to the ground. The drawer bottom is hinged at its rear end at the rear wall of the drawer. Appropriate stops limit the inclination of the drawer to an angle of 18 deg. when the drawer is open. Along the lateral walls of the drawer (10) at the upper part are mounted two supports (32, 34). These supports are designed to pivot around an axis parallel to their longitudinal direction.
Patent FR-2342059-A1 (FR)
Inventor: BILLEK DORIS
IPC: A61Q19/00
Filed: 1977-02-28
Abstract: Cosmetic composition for smoothing the human skin with softening effect on the horny layers of the skin and for treating and controlling hyperkeratotic states. Besides the softening effect on thickened and hardened horny layers, the composition brings about hydration of the skin and acts as a protective for retention of the skin's own amino acids so that it is suitable as a protective against the effects of weather conditions and of detergents and washing agents. The composition contains, besides the conventional cosmetic ingredients and, where appropriate, a sunscreen agent, as active, skin-softening component urea in an amount of 1 - 5% by weight and, as stabiliser for the urea, not more than 10% by weight, based on the urea, of a stable, odour-neutral, non-volatile physiologically tolerated aliphatic dicarboxylic acid which has low solubility in a lipid phase, and the composition has a pH in the range 4 - 7. The content of stabiliser means that, in any form, the cosmetic composition is stable and can be stored without a change of state for a long period.
