Inventor: PALESTRANT AUBREY M
IPC: A61F2/01
Filed: 1989-07-06
Abstract: A blood clot filter (20) is composed of a number of peripheral wires (28-38) joined at one end by a first connector (40) and also joined approximately at their middle portions by a second connector (42). The wire portions extending between the two connectors form a filter mesh (52), and the wire portions extending between the second connector and the free ends form filtering legs (51) which anchor the filter. The filter mesh is formed when a central core wire, which is fixedly secured to the first connector and slidingly extends through the second one, is retracted to slide the two connectors together. A lock device prevents the two connectors from sliding back apart. The wire strands may initially be substantially straightened in order to permit insertion of the filter into the lumen of an angiographic catheter. A pusher catheter extending within a delivery catheter pushes the filter out of the delivery catheter and into the lumen of the blood vessel. A retractor cable extends through the pusher catheter and is releasably coupled to the central core wire for retracting the same.

Abstract: A method of and apparatus (Fig. 4) for recording an information signal (Vi), in particular an EFM-modulated signal, are revealed, which information signal comprises time-code signals which alternate with first time-synchronisation signals. The record carrier (1) which is employed is provided with a preformed servo track (4) which exhibits a periodic track modulation whose frequency is modulated in conformity with the position-information signal (Fig. 2). The position-­information signal (Fig. 2) comprises position-code signals (12) which alternate with position-synchronisation signals (11). During recording a fixed phase relationship between the time-synchronisation signals and the position-synchronisation signals (11) is maintained, so that the portion (141) of the servo track (4) in which the time-synchronisation signals are recorded are situated at fixed positions relative to the servo-track portions (140) which represent the position-synchronisation signals (11).

Abstract: A method of reducing the volatility and decreasing the evaporation loss of water repellent compositions containing a solution of an alkylalkoxysilane and a carrier prior to application of the composition to a porous substrate by acidifying the solution in order to cause rapid equilibration of the alkylalkoxysilane and the carrier to a constant steady state condition, adding to the acidified hydrolyzed alkylalkoxysilane solution at least one metal salt catalyst to further increase the hydrolysis rate of the alkylalkoxysilane and to complete the hydrolysis and the condensation of the alkylalkoxysilane, adding at least one surface depositing agent to the acidified hydrolyzed alkylalkoxysilane solution in order to reduce evaporation of un-reacted alkylalkoxysilane and maintaining the solution in a substantially anhydrous condition, so that the amount of hydrolyzed silane absorbed by the porous substrate and the percentage of water excluded from the porous substrate by the repellent composition are increased.

Abstract: An optical 1xN star coupler has a single mode input fibre I and N single mode output fibres O₁ forming an output fibre assembly. The output fibres O are tapered within a former 2 which holds each output fibre O so it is positioned substantially identically relative to the remaining output fibres. The input fibre I is also tapered such that the fundamental mode field of the input fibre I and output fibre assembly are substantially equal. The identical relative positions of the output fibres O provides a wavelength independent 1xN star coupler.

Abstract: Sintered-carbide blades (3) are inserted in grooves (2) of the rotor body (1). Each blade (3) has at both ends in each case a cylindrical or conical clamping surface (7), against which a conical surface (6) of a cone screw (5) bears and secures the blade in the groove (2) with a clamping force (F). The blades (3) are thus securely held in a specific position not only radially and in the circumferential direction but also axially. The shapes of the blades (3) and grooves (2) and the clamping means in the form of cone screws (5) are readily obtained and easy to handle. Dirt accumulation in the blade-clamping arrangement is virtually eliminated.

La tête de lecture est réglée lorsque les courbes de Lissajous coïncident. On a aussi mis au point des agencements plus simples et moins précis, dans lesquels un signal de sortie de courant continu variable est produit, lequel représente le rayon d'une courbe de Lissajous hypoghétique dérivable des signaux (14, 16). Ladite tête de lecture est ensuite réglée pour donner une sortie de courant continu constante, représentant un rayon de courbe de Lissajous constant.

Abstract: Système de réglage antiblocage où le glissement des roues sert de paramètre de réglage. La vitesse de référence requise pour produire le glissement est obtenue à l'aide d'une valeur de référence auxiliaire, qui indique l'accroissement de référence en cas de baisse soudaine de la vitesse des roues. Sinon, on tient compte de la vitesse de la roue qui occupe le second rang en termes de vitesse pour établir la valeur de référence en mode de réglage. En dehors du mode de réglage, c'est la valeur moyenne des roues avant qui détermine la vitesse de référence. On passe d'un mode de détermination de la vitesse de référence à l'autre - soit de la valeur moyenne à l'utilisation de l'accroissement de la valeur de référence auxiliaire et de la vitesse de la seconde roue en termes de vitesse - aussi bien au début du réglage qu'en l'absence de ce réglage, lorsque la somme des valeurs de tous les glissements de roue dépasse une valeur-limite (a).
