Abstract: A magnetic resonance (MR) compatible transducer for magnetic resonance elastography applications has a cantilevered drive element a free end of which is arranged in use to move reciprocally, and a flexible non-conductive connection rod slidably disposed within a flexible non-conductive sleeve. The connection rod is affixed at a proximal end to the cantilevered drive element via a proximal flexible connection piece that in use accommodates the slight rotational movement of the cantilevered drive element as it reciprocates about its secured end, whilst translating the rotational reciprocation of the cantilevered drive element into a pure translational reciprocation of the connection rod within the sleeve. The distal end of the connection rod is affixed against a protrusion connected to another cantilevered driven element, upon which is mounted a piston element that in use contacts the subject.

Abstract: A cylinder lock, especially for motor vehicles, comprising a housing (1) in the inner cylindrical cavity of which there is arranged a cylinder core (2) that is equipped with a key channel (22) and spring-loaded tumblers (20, 20?), wherein, when no appropriate key is fully inserted into the key channel (22), blocking projections (201) of the tumblers (20, 20?) protrude into a blocking groove (13, 13?) formed in a member in which the cylindrical core (2) is supported for turning and, when the appropriate key is fully inserted, the blocking projections (201) of the tumblers (20, 20?) do not extend beyond the periphery of the cylindrical core, wherein the cylinder lock is further provided with means for coupling the cylindrical core (2) with an output member (3) of the cylinder lock when the cylindrical core is being turned by the appropriate key, and for uncoupling of the cylindrical core (2) from the output member (3) of the cylinder lock when the cylinder core is turned by means of a false key or forcibly, the

Abstract: A cylinder lock, especially for motor vehicles, comprising a housing (1) in the inner cylindrical cavity of which there is arranged a cylinder core (2) that is equipped with a key channel (22) and spring-loaded tumblers (20, 20′), wherein, when no appropriate key is fully inserted into the key channel (22), blocking projections (201) of the tumblers (20, 20′) protrude into a blocking groove (13, 13′) formed in a member in which the cylindrical core (2) is supported for turning and, when the appropriate key is fully inserted, the blocking projections (201) of the tumblers (20, 20′) do not extend beyond the periphery of the cylindrical core, wherein the cylinder lock is further provided with means for coupling the cylindrical core (2) with an output member (3) of the cylinder lock when the cylindrical core is being turned by the appropriate key, and for uncoupling of the cylindrical core (2) from the output member (3) of the cylinder lock when the cylinder core is turned by means of a fa
