|1. WO/2015/142226 UNDERGRAVEL FILTER FOR AN AQUARIUM||WO||24.09.2015|
||PCT/SA2015/000003||ALTHUMAYRI, Bassam||ALTHUMAYRI, Bassam|
The invention relates to a undergravel filter for an aquarium. The filter is disposed at the bottom of the aquarium and draws in all types of impurities, inter alia, before expelling them towards the external filter. The filter comprises: two funnels for each part of the filter such that they each form a container which directs all the matter which slips thereinto to the discharge aperture, at the base of each funnel (10). The discharge tube is triangular (11) and is located between the two funnels from which it draws in water and the impurities via the discharge aperture at the base of the funnels, on the wall of the tube. A further, wider, tube (23) draws in water and the impurities from the discharge tube and directs them towards the suction tube.
|2. WO/2015/137851 METHOD OF PRODUCING RENEWABLE ELECTRICAL ENERGY BY GRAVITY||WO||17.09.2015|

The invention relates to a method of producing electrical energy which consists simply in allowing a mass to fall vertically from top to bottom on a surface connected to a sensor, under the effect of gravity, which draws the mass to the ground. The fall of the mass causes the rotation of the drive shaft, which is connected to the other end of the pulley cable, which unwinds in the opposite sense, the effect of which is to tension the spring secured to the pulley and activate the gearbox such that the motor speed is decoupled and energy is generated. When the mass rises again, the spring retains the excess latent energy. The signal received from the sensor enables at most 40 % of the energy generated by the main motor to be used to help the spring to release the latent energy and convert it into kinetic energy, thus enabling the mass to rise. The secondary motor, which is connected to the main motor, compensates the loss of energy used to raise the mass. Unlike the main motor, which generates energy and uses the amount thereof necessary to raise the mass, the secondary motor generates energy in both directions of movement of the mass owing to the fact that it rotates clockwise and anticlockwise. The motors used are connected in series to a device for storing the energy generated (battery).
