Title: Two-element roller skate (rolling footwear) device for individual movement
Inventor: ALAIN CROS MICHEL LOUIS
IPC: A63C17/02
Filed: 1990-09-04
Abstract: Two-element roller skate device for moving individually over any surface which is suitable for motor vehicles. The invention relates to a device composed of two elements to be worn on the feet, equipped with two wheels arranged so as to obtain great stability, by virtue of a wheelbase (1) which is greater than the length of the foot increased by two wheel radii and by virtue of the short distance between the foot and the ground (2). Each element is equipped with a braking device controlled by the rocking (5) of the person's foot about the axis (6). An optional steering system operates by lateral pressure of the heels, giving rise to a rotation of the rear wheel about the axis (7); the principle of the axles pivoting by inclination may also be used. The structure of the element advantageously permits the insertion of the foot via the rear and holding of the ankle (10). The elements include a suspension, preferably by means of elastic flexing of the chassis (11), a disengageable anti-backslip device, a carrying handle (12), an integral anti-theft device and a mudguard (anti-splash structure) (13). The invention relates to the two rolling elements and a complementary portable sail permitting propulsion using the wind. The device according to the invention is intended particularly for participating in leisure or competitive sports and for short tourist-type, domestic or professional journeys.
Patent FR-2666897-A1 (FR)
Inventor: LOUIS JUNG
IPC: G01N27/447
Filed: 1990-09-19
Abstract: The inner walls of capillary tubes being fine and of small diameter are provided with a continuous positively charged coating which is used in capillary electrophoresis and is prepared by chemical reaction between the capillary tube inner surface and a bifunctional substance. The first chemical grouping of a bifunctional substance is capable of forming a covalent bond with the capillary tube inner wall surface; the second grouping contains one or more stable, continuous positive charges, possibly in the form of quaternary ammonium. The stable, continuous, positive charge in the capillary tube inner surface coating has a twofold effect: it reverses the direction of the electroosmosis flow while at that same time increasing its value relative to non-treated capillary tubes or to negatively charged or uncharged coatings. The presence of this coating serves to separate several chemical substances at the same time which would not be possible otherwise. It also substantially reduces the adsorption of substances on the capillary tube inner walls using a mecanism different to other types of coatings which improves separation characteristics.
