Abstract: The invention consists of uncoupling the actuation lever (6) of the device from the main body thereof, such that the same ceases to be integral and becomes pivotable by means of a rotation axis (7), such that it is connected to the head (2) by means of a transmission that reduces the force required to actuate the lever, as well as varies the range of angles in which the lever is effective, thereby making the use of the device easier, more comfortable and more accurate. The device has means for uncoupling the transmission between the lever and the head, surpassing a degree of inclination for the main body that can be dangerous, a mechanism that can be disabled by means of a pin passing through a hole (10) made in the lever (6).

Abstract: A self-braking descender having a panic function and being formed by a body including a channel through which a cord extends in both directions. One end of the body is provided with an actuation lever formed by two projecting sides, a solidly connected appendage and a friction hole through which the cord also extends, and the lever can be folded onto the body. The other end of the body is provided with a head formed by a preferably semi-circular part including two projections and a rear cam with toothing in order to increase the friction in the panic position. An assist element for controlling the sliding of the cord is also included.

Abstract: A solder-free laser module which comprises at least one laser chip clamp-mounting between electrodes. The laser module includes: some electrodes facing each other and having opposite poles; insulating separators placed between the facing surfaces of the electrodes to prevent direct contact between them and their short-circuiting; laser chips mounted between the facing surfaces of said electrodes, making contact with the electrodes, and clamping means for bringing the electrodes facing each other more closely together to ensure their contact with the laser chips positioned between them, thereby ensuring electrical power supply to the aforesaid laser chips and dissipation of the heat generated. The invention further relates to a method for assembling the aforesaid laser module.
