Abstract: A holder system for supporting and accommodating a laptop computer or other device comprises —an extendable/retractable carrier system provided with frame portion means for attachment to a tabletop; —a holder and support member for holding and/or accommodating and/or supporting a laptop computer or other device, and —pivot means pivotally connecting said carrier system and said holder and support member, whereby the holder and support member can be brought from a substantially vertical orientation to a substantially horizontal orientation when the carrier system is in its extended or drawn out position. The holder system according to the invention is provided with a pull handle and associated rod system enabling locking of the holder and support member in the horizontal position by releasable engagement between a distal end portion of the rod system and corresponding engagement means provided on said frame portion means of the holder system.

Abstract: A bar or column shaped telescopic device comprising at least three telescopic parts with a first part (3), a middle part (2) and a second part (1), that are in telescopic engagement with each other. A first (4) and a second (7) adjusting screw extend inside the telescopic parts, and the first adjusting screw is connected to the first telescopic part (3) and is in threaded engagement with a nut (5) mounted onto the middle telescopic part (2) in such a way that said nut (5) is turnable about the longitudinal axis of the first adjusting screw. The second adjusting screw (7) is connected to but turnable in relation to the middle telescopic part (2) and in threaded engagement with the second telescopic part (1) via a nut (8). The device comprises driving means (11) for rotating the nut (5) and the second adjusting screw (7) simultaneously.

Abstract: The present invention relates to novel compounds of the following formula: ##STR1## individual isomers and pharmaceutically acceptable acid addition salts thereof, wherein R.sub.1 is hydrogen, alkyl or phenyl-lower alkyl, in which the phenyl group may be substituted with halogen, lower alkyl or lower alkoxy; R.sub.2 is alkyl, alkenyl, alkynyl or phenyl-lower alkyl, in which the phenyl group may be substituted with halogen, lower alkyl or lower alkoxy; and R.sub.4 is hydrogen or alkyl.The invention moreover relates to methods for the preparation of the compounds of formula I, to novel intermediates, to pharmaceutical compositions containing same and to methods for the treatment of disorders, caused by malfunction of the acetylcholine (AcCh) or muscarinic system, by administering a non-toxic effective amount of a compound of the formula I.
