Title: Puits de lumiere
Inventor: MASSAAD TONY K H
IPC: F21V13/04
Filed: 1998-10-13
Abstract: Normalement, le puit de lumière n'est qu'une ouverture dans la toiture pour laisser passer la lumière et le soleil à travers l'attique, pour éclaircir les pièces obscures. En hiver de grosses quantités de chaleur se perdent par cette large ouverture. Dans mon invention je remplace la grande ouverture par un orifice de 20 cm.de diamétre , et la boîte du puit de lumière, par un tuyau de 20 cm. de diamètre ou moins, qui relie la toiture au plafond de la piéce à éclairer ,en passant par l'attique. Ce tuyau sera isolé bien sûr à son éxtérieur, et ses parois intérieures seront miroitantes. Ce même tuyau sera surmonté du côté de la toiture par une lentille convexe, d'un diamétre de 100cm. N. (1) contenu dans un cône en dessous de laquelle se trouve une autre lentille convexe de(+ou-) 15cm. de diamétreN. (3) , et au fond du tuyau c.à.d. le plafond de la pièce à éclairer se trouve un miroir légèrement convexe de ( + ou - ) 10 cm. de diamétre N. (4) qui est penché à45 degré et qui divergera les rayons sur le mur ou sur un autre miroir légèrement plus convexe que le précédent N. (5) de diamètre de(+ou-) 20 cm. qui lui divergera les rayons à travers un écran diffuse de 1 x1 m.ou sans écran à travers la chambre. La lentille convexe de 100 cm.de diamètre est recouverte par un dôme en verre ou en plastiqueN. (7) La lentille convexeN. (1), située sur la toiture prendra les faisceaux lumineux et solaires , et les convergera vers son foyer N. (2 ) en une tâche trés petite ce même foyer N. (2) sera le foyer de la lentille suivante N. (3) dont les rayons sortiront forcément parrallèles cette dernière lentilleN.(3) les enverra jusqu'au mirior légèrement convexe suivant, N. (4) qui lui les divergera jusqu'au mirior N. (5) qui est légèrement plus grand et plus convexe et qui les divergera d'avantage à travers toute la chambre.

IPC: B01J31/18
Filed: 1998-11-04
Abstract: A process for the manufacture of trans-(R,R)-actinol by diasteroselective transfer hydrogenation of levodione comprises hydrogenating (R)-levodione in the presence of a hydrogen donor, which simultaneously can be used as the solvent, and an amino-amide--ruthenium complex, especially of the formula RuH(L{-H})(Y), wherein Y signifies a neutral ligand and L signifies an optionally optically active monosulphonylated diamine ligand, as defined in more detail in the description.     Moreover, the invention is concerned with some of the amino-amide-ruthenium complexes and with the corresponding precursors to these complexes, which have halogen in place of H. The product of the process in accordance with the invention, trans-(R,R)--actinol, is known as an important building block for the synthesis of carotenoids, e.g.  zeaxanthin. By the process trans-(R,R)-actinol is made available in particularly high enantiomeric and diasteromeric purity.

Title: Mouse cleaning apparatus
Inventor: MIHALYNUK MITCHELL GEORGE
IPC: G06F3/039
Filed: 1999-04-16
Abstract: A mouse cleaning apparatus is used to remove accumulated dirt from the internal rollers and tracking ball of a mechanical transducer known as a "mouse" commonly employed in modern computer systems. A small DC motor together with its switched power source are housed in a palm-sized plastic case. The motor axle extends beyond the case through the axis of a plastic sphere. A gently abrasive material is attached to the circumference of the sphere such that it covers the sphere areas in contact with the rollers. During operation, the plastic sphere is inserted into the mouse housing in place of the tracking ball. Switched on, it results in gentle spinning and cleaning of the mouse rollers. A concave external surface of the apparatus, also covered with gently abrasive material, may be used to clean the mouse ball.

Title: Machine for printing flat objects, in particular envelopes, with printing drum and thickness compensating device
Inventor: VIENNET FRANCK
IPC: B41F13/008
Filed: 1998-08-21
Abstract: The invention concerns a machine comprising two feed rollers (3, 14), one of which at least is a power-operated roller, and a rotating printing drum (6) co-operating with a counter-printing power-operated roller (17).
