Abstract: A light guide (1) for a lighting device (8) is provided. The light guide (1) comprises an incoupling element (2) configured for receiving light and coupling the received light into the light guide (1). The light guide (1) is configured to convey the received light within the light guide (1). The light guide (1) comprises at least a first group and a second group of conically shaped outcoupling surface structures (3) distributed on, and recessed into or protruding from, a side (4) of the light guide (1). Each conically shaped outcoupling surface structure (3) is configured for coupling of light out of the light guide (1). Further, each conically shaped outcoupling surface structure (3) of the first group is geometrically characterized by a shape in accordance with a first cone or conical frustum (5) and each conically shaped outcoupling surface structure (3) of the second group is geometrically characterized by a shape in accordance with a second cone or conical frustum (6).

Abstract: The invention relates to a handling device for drill pipes (18) and to a so-called top drive (16) comprising said handling device, a so-called pipe handler, and having means for detecting a position of an elevator bail (30) comprised by the handling device/pipe handler and for transmitting the associated position information, wherein the position information is transmitted from the pipe handler to, e.g., the top drive (16) and is converted into an electrical signal for detecting and avoiding potentially critical situations as a result of a position/deflection of the elevator bail (30).

Abstract: The invention relates to a group of novel piperazine and piperidine derivatives of formula (I), wherein: S1 is hydrogen, halogen, alkyl (1-3C), CN, CF3, OCF3, SCF3, alkoxy (1-3C), amino or mono- or dialkyl (1-3C) substituted amino, or hydroxy; X represents NR3, S, CH2, O, SO or SO2, wherein R3 is H or alkyl (1-3C); . . . Z represents ═C or —N; —R1 independently represent H or alkyl (1-3C), or R1 and R2 together can form a bridge 2 or 3 C-atoms; R4 is hydrogen or alkyl (1-3C); Q is methyl, ethyl, ethyl substituted with one or more fluorine atoms, cyclopropyl—methyl, optionally substituted with one or more fluorine atoms, and salts and prodrugs thereof. It has been found that these compounds have both partial dopamine D2-receptor agonism and partial serotonin 5-HT1A-receptor agonism mediated activities.

Abstract: The present invention is concerned with compounds having 5-HT1A antagonistic activity useful in treating CNS disorders and having formula 2 ##STR1## wherein R.sub.1 is halogen, lower alkyl or alkoxy, hydroxy, trifluotomethyl or cyano,m has the value 1 or 2 and n has the value 0 or 1,A represents an alkylene chain containing 2-6 C-atoms which may be substituted with one or more lower alkyl groups or a monocyclic (hetero)aryl group, andB is methylene, ethylene, carbonyl, sulfinyl, sulfonyl or sulfur, and salts thereof.

Abstract: It has been found that a group of piperazine derivatives known to have blood-pressure lowering properties possess good anxiolytic properties. In two well known animal test models the compounds are active when used intraperitoneally in dosages of 0.3 mg/kg.
