Patent EP-0010407-A1 (EP)
Inventor: TREADWELL KENNETH
IPC: C08G18/22
Filed: 1979-10-11
Abstract: Rigid polyurethane foam is prepared by reacting a polyol containing at least three active hydrogen atoms with a polyfunctional isocyanate or isothiocyanate in the presence of a gel catalyst and a blowiegagent. As gel catalystthere is used a catalyst composition comprising an antimony carboxylate, a potassium carboxylate and a zinc carboxylate wherein the hydrocarbyl as hereinbefore defined portion of each carboxylate contains from 1 to 2a carbon atoms and wherein each of the antimony and potassium carboxylates constitutes from 10 to 40 % by weight of the total carboxylate content and the zinc carboxylate constitutes the remaining 20 to 80% by weight of the total carboxylate content, either alone or in combination with another gel catalyst, particularly one chosen from tertiary amines, inorganic tin compounds an organotin compounds. The use of the specified gel catalyst composition enables the isocyanate- or isothiocyanate- polyol reaction to be controlled over a wide range.

Abstract: A pipetting and dosing device, in particular for use in automatic clinical analysis apparatuses, for dosing and dispensing accurate liquid volumes, such as samples and reagents, comprises an internally cylindrical suction pipe (5) with a conically tapering distal end (17) with a central opening (18), a piston (7) axially movable within the suction pipe while sealing against the inner wall of the pipe, and drive means (8-13) for moving the piston axially over well-defined distances in the suction pipe for, respectively, sucking up and discharging predeterminable volumes of liquid. The end of the piston facing the conically tapering distal end (17) of the suction pipe (5) is provided with a conical tip (7a) having an apex angle somewhat larger than the apex angle of the coni cally tapering end of the suction pipe and this conical piston tip (7a), or alternatively the conically tapering end (17) of the suction pipe, is made of a resiliently deformable material. At the end of the discharge movement of the piston in the suction pipe the conical tip (7a) of the piston is moved into abutment against the conically tapering end (17) of the suction pipe with such an axial force that, through elastic deformation of the piston tip or alternatively the conically tapering end of the suction pipe, the piston tip and the conically tapering end of the suction pipe are brought into complete conformity without any residual interspace remaining therebetween.

Abstract: Afin de separer automatiquement une chaussure de ski, du ski en cas de danger, ce procede prevoit d'integrer continuellement les forces agissant sur la jambe du skieur. Si l'integrale de temps de la force mesuree atteint une valeur seuil representant le produit de la force X temps et depassant la valeur seuil d'integration correspondant a1a force de retenue de la fixation, la liaison entre le ski et la chaussure est rompue. Pour pouvoir adapter une fixation de securite aux differentes conditions, telles que habilite et technique du skieur, structure osseuse du skieur, etat de la neige et du terrain, on varie la courbe de declenchement (12', 13', 14') en modifiant la valeur seuil d'integration independamment de la force de declenchement statique.

Abstract: For driving over snow covered roads the wheels of the vehicle are fitted with a set of rings. The tool used to fit the rings consists of a centre plate (2) with bearings supporting a shaft (6) which can be rotated by the handle (3). The shaft carries two pinions each of which engages two toothed racks forming part of rigid bars (1). Rotation of the handle (3) in a clockwise direction causes the four bars (1) to move inwards simultaneously. A hole at the end of each bar receives the hook of a tension spring (10) which is connected to a chain attached to the flexible ring. As the bars move inwards they clamp the ring (9) onto the tyre.

Abstract: A boring cutter (15) and a honing stone (13) are coaxially arranged at a working head (11). A bar member (9) is reciprocatingly inserted and splined within a rotating hollow spindle (5). Both the end opening surface (5a) of the spindle (5) and the end (9a) of the bar member (9) are so taper engaged that the member (9) may be fed forwardly with respect to the spindle (5). The machining head (11) is coupled with the end surface of the member (9). When the shaft (5) is taper engaged with the member (9), a workpiece is bored. When the member (9) is moved forwardly to release the taper engagement, the member (9) and the head (11) are reciprocated to thereby hone the workpiece. Thus, the construction is formed rigidly to thereby hone the workpiece, and to thereby both bore and hone the workpiece.
