Abstract: The invention deals with an adjustable wrench comprising: a first jaw (8) and a second jaw (10) movable relative to the first jaw (8), wherein the second jaw (10) comprises a rack (12), a worm gear (18) movable into an engaged position wherein the worm gear (18) engages the rack (12) and wherein a rotation of the worm gear (18) causes the second jaw (10) to move relative to the first jaw (8), and into a disengaged position wherein the worm gear (18) does not engage the rack (12), a body (2) defining two surfaces, one of the surfaces comprising a first portion (14a) and a second portion (14b), the other surface comprising a third portion (16a) and a fourth portion (16b), the first portion (14a), the second portion (14b), the third portion (16a) and the fourth portion (16b) comprising a first point (140a), a second point (140b), a third point (160a) and a fourth point (160b) respectively, a biasing element (20) configured to urge the worm gear (18) toward the engaged position by applying forces on both surfaces

Abstract: The invention relates to a lighting device including a power supply housing, a lighting head including at least one light source, and a connection arm having an elongated shape. The arm includes a first end connected to the housing and a second end connected to the head in order to mechanically connect the housing and the head, the latter being mobile relative to the housing between a first position in which the head is in the vicinity of and/or connected to the power supply housing, and at least a second position in which the head is remote and/or disconnected from the housing. The length of the arm is shorter than or equal to the largest dimension of the power supply housing.

Abstract: The invention relates to a portable lighting device that includes a power supply housing; a lighting head comprising at least one light source; a linking arm linking the housing and the head; a holding member of the lighting head; the latter being mobile relative to the housing between a first position in which the head is close and/or secured to the housing and a second position in which the head is distant and/or not secured to the housing, the holding member being secured to the housing and fitted to maintain the head in a fixed position relative to the housing in the first position of the head. The holding member includes a mobile element relative to the housing, adapted to hang the housing on an external mounting.

Abstract: A support is for supporting electrical and/or electronic structure and/or electrical power supply structure for a hand dynamometer tool, in particular for a torque wrench operating by breaking mechanical equilibrium. A body of a substantially cylindrical shape that extends along a longitudinal axis, defined by two end faces, recesses and/or seats suitable for receiving electrical power supply members and/or electrical/electronic circuit boards are arranged and distributed around the axis, on or close to a periphery of the support. The support can be applied to a support module for a hand dynamometer tool and to a dynamometer tool.

Abstract: A means for detecting a break in mechanical equilibrium comprised of a measurement means that delivers a signal corresponding to a measurement of a torque applied to a fastener element, an electronic processing means for electronically processing a signal, and a computation processing means for computationally processing data output from the electronically processing of the signal. Application to a hand dynamometer tool.

Abstract: A number of racks make up a stack. An upper rack includes releasable catches received into orifices in the next lower rack to releasably attach the two racks to one another. A loader and receptacle cooperate with one another to release the bottommost rack from the stack and deposit it into the receptacle where pipette cones held therein are accessible for use. The bottom rack is placed into the loader where it is held by catches engaging ribs of the rack. The stack of racks with the loader attached is placed onto the receptacle. The stack of racks is pressed downwardly. The downward movement releases the bottom rack from the loader. At the same time, studs projecting up from the bottom of the receptacle engage catches of the second-from-the-bottom rack and free the bottom rack. The bottom rack now rests freely in the receptacle.

Abstract: A rack for pipette cones (in particular multichannel cones) includes orifices in a line forming at least one row along at least an alignment direction and a support surface adapted to support cones housed in the orifices. The rack provides for simultaneous access to at least some of the cones in the row. The support surface has a generally convex transverse outline along the alignment direction.
