PROCESS FOR DETERMINING THE BACKUP TIME OF A BATTERY The backup time (T) of the battery is obtained lay simulation, in iterative manner, of discharging of the battery during successive simulated time intervals (.DELTA.T). During each of the simulated time intervals, a simulated discharging current (i) in terms of the actual discharge power (P), a simulated voltage (E), and a simulated state of ch...

Failure of one or more battery cells, for example of an inverter battery bank, is detected by monitoring the second derivative (D) of the curve U(t) representative of the voltage U at the terminals of the battery in the course of discharge. If the second derivative is positive (F7), this is significant of a failure.

The gradual motion variator of this invention is a mechanism allowing variation in the speed of rotation of an axle of any given power transmission. The principle adopted is elastic diametric deformation of a gear pair, increasing one of them decreases the other, thus modifying the ratio. The number of ratios is equal to the number of teeth, obtained from the difference between the maximum and min...

A lock for vehicles, of the type which comprises a security device which can be controlled from the exterior of the vehicle by means of a control lever using a key, in which the lever for key control of the security locking device of the lock has a member which is designed to act together with a microswitch activating member inserted in the centralised activating control circuit of the complementa...

System for measuring the effective index of refraction of a group of optical fibres, in which one sends into a piece 2 of fibre being examined the radiation emitted by a source 1 of variable wavelength and performs a Fourier analysis of the spectral transmission function of the fibre, considered as a resonating cavity. Between the source 1 and a computer 7 performing said analysis are arranged mea...

The beam power of a laser beam is sampled by arranging a conduction pathway for the radiation, extending transversely and essentially normal to the axis of the beam, and detecting the light emitted from at least one of the ends of the radiation pathway, the radiation at the end of the radiation pathway being representative of the power of the laser beam. The radiation conduction pathway can be a g...

A fragment and/or derivative of α 1 timosine, which may be in the form of a pharmaceutically acceptable salt, is used as an antagonist in depression of the immunological reaction produced by antitumoural agents.

A process for production of vanadium-containing agglomerate, includes the steps of providing a spent, vanadium-containing, iron based hydroconversion catalyst; incinerating the spent catalyst in the presence of an oxidizer until a sulfur content of the spent catalyst is reduced to 2% or less by weight; grinding the spent catalyst to a particle size suitable for a desired use; and mixing the spent ...

Device for mounting tools on tool holders and removing them therefrom, where the tool holders are of the one- piece or flanged type, used on machine tools in the mechanical engineering industry, the device consisting of a fixed base 2, provided with a rotating flanged plate 3 on which is fixed the support 4, which acts as the container of the tool holder 5 (Fig. 1).

This innovation provides carrier posts B for debris barrier nets. Under impact and under loads of fallen material the posts do not bend and twist but instead adapt to the new load condition, and can always be restored to their initial position or to some other desired position. A characteristic of the innovation is that the posts B are provided with a seat C consisting of a plate 11 in which their...
