Abstract: Dihydropyridine deriv.-drug cpds. of formula D'-DHC (I) and their salts are new, (D' is a centrally or testicularly acting drug species; and DHC is the reduced bio-oxidisable blood-brain barrier penetrating lipoidal form of a dihydropyridine in equilibrium with a pyridinium salt redox carrier. Provided that when DHC is 1-R-1,4-dihydro-3-pyridinylcarbonyl (R is lower alkyl or benzyl) and D' is a drug species contg. a single NH2 or OH gp. (as a p- or s-OH) linked directly through the NH2 or OH to the carbonyl function of DHC, then D' is not a sympathetic stimulant, steroid sex hormone, memory enhancer, long chain alkanol or anticancer or antitumour agent). (I) give site specific and sustained delivery of the centrally acting drug to the brain. They readily and easily penetrate the blood-brain barrier so that increased concns. are present in the brain; oxidn. of the dihydropyridine carrier in vivo to an ionic pyridinium salt prevents its elimination from the brain, while elimination from the general circulatory system is accelerated. This action ensures prolonged brain-specific action, while any systemic toxic effects are decreased and central toxicity is reduced. Site specific and sustained delivery to the testes is also achieved, esp. with drugs that cannot themselves penetrate the blood-testis barrier; they are useful for male contraception, improving sexual function esp. in veterinary use, etc.

Granted: 1989-05-31
Abstract: Procédé de conception d'un instrument binoculaire compact de vision nocturne avec un intensificateur électronique d'image (2) (ou similaire) qui est orienté de sorte que son axe de symétrie forme un angle droit avec la ligne de collimation (19) entre l'instrument binoculaire de vision nocturne et la scène à observer. La longueur totale vers l'avant devient de ce fait particulièrement courte, réduisant ainsi le couple descendant ce qui pose un problème lorsque l'instrument binoculaire de vision nocturne est porté comme une paire de lunettes attachées autour de la tête (appelées généralement des lunettes de vision nocturne). La longueur totale vers l'avant peut même encore être réduite si l'axe de symétrie de l'objectif (1) est également orienté à angle droit par rapport à la ligne de collimation (19). Ces mesures permettent d'agencer un système diviseur de faisceaux simples où l'axe optique passant à travers l'un des occulaires (13B) coupe l'axe optique commun passant à travers le diviseur de faisceaux (14). L'invention ci-décrite permet de réaliser un instrument logé dans un seul boîtier de forme extérieure lisse et de préhension aisée.

Abstract: The suspension device (10) has a tilting panel (11), a beam (15) to be suspended from a ceiling (14), and a hanging arrangement (16) for hanging a part of the body. The tilting panel can be turned to and fro at one end about a pivot axis (19). The other end is connected via a cable (12) to one end of the beam. The hanging arrangement is connected to the other end via a connection part (17). When a person (25) suspended in the hanging arrangement steps on the tilting panel, the free end of the latter moves downwards, this movement being transmitted to that end of the beam to which the cable is secured. In this way, the other end of the beam, and with it the hanging arrangement, moves upwards, as a result of which the suspended person is relieved. This relief is greater or lesser depending on where the pressure point (28) of the foot lies on the tilting panel. If the person has placed his legs upon the tilting panel at different distances from the pivot axis thereof and if he rocks from one foot to the other, or bends and stretches the legs lightly and relatively quickly, continuous alternation between relatively strong and relatively slight relief can be obtained. <IMAGE>

Abstract: A stabilised mount [e.g. for an antenna (13)] has two gyroscopic rotors (23, 24) mounted in such a way that they can pivot about orthogonal axes (26, 27). Rewinding of the antenna (13) (to avoid undue twisting of the electrical cables) is liable to cause a violent destabilisation of the mount because of the gyroscopic action of the rotors (23, 24). To prevent this destabilisation the rotors (23, 24) are locked against the aforementioned pivotting action during the rewinding procedure.
