Abstract

The invention relates to a device for measuring rheological properties and monitoring pressurised processes. The device is characterised in that it is connected to the motor by means of a shaft (1) which is designed to minimise the transmission of heat therefrom to the motor and which is tightly fitted in the cover (2) of the external magnets, said cover including two adjustment screws (3) for adjusting the proximity of the repelling magnets (5) and (6). By means of this adjustment, it is possible to cancel the axial attraction force exerted between the lateral magnets (4) and (12). These lateral magnets are distributed at a distance from the rotation axis of the stirrer and, as such, effectively transmit the torque, however, the attraction forces are cancelled by the central adjustable magnets. This means that, in respect of the outer part of the device, the shaft of the motor does not experience axial stresses. In respect of the stirrer or internal geometry (15), this allows the weight thereof to be cancelled such as to minimise the interference of mechanical friction in the measurement of the rheological properties.

Abstract

The invention relates to an inflatable jacket (1) that can be adapted to the body of a worker and automatically inflates in the event of a fall of the worker from a height. The invention is based on a gas cylinder which is instantaneously opened and emptied as a result of the corresponding signal generated by a central electronic system also built into the jacket (1), said system receiving the information from a series of sensors arranged in the soles (3) of the footwear (6) of the worker, and a pulsometer (2) arranged on the thorax, when the worker's feet leave the ground due to a fall and the pulse of the worker increases. The equipment is completed with a high-quality anti-fall harness (14), which ensures the suspension of the worker in the air and prevents said worker from falling and hitting solid ground.

Abstract

The invention relates to a dendrometer based on a linear positioning sensor which transforms variations of the position of its corresponding piston, which is in contact with the plant, into voltage differences captured by an electronic recorder connected to the sensor, in the vicinity of same, by means of a cable consisting of three high-impedance wires, in such a way that the reading of the radial variations of the plant studied or measured is taken in volts, the ratio between voltage and length being 1 mV (4 micrometres). The precision of the device is determined by the capacity of the recorder, the resulting resolution for 12 bits being 0.61 mV (2.44 micrometres), enabling the study of the daily variations of the plant, generated by the hydric status of same, along with the accumulated radial growth of the stem or branches and the duration of the vegetative period.
