Abstract

The electrical energy generator uses the variation of wind pressure transmitted to a quartz or ceramic piezoelectric element. The generator may be housed on a vehicle bonnet and used to assist battery charging. Alternately the generator may be housed in lines to a sail or branches of a tree. The piezoelectric element (29) is housed within a double cage to increase the possible element size. The cages consist of upper and lower plane surfaces spaced by corner pillars, the base of the larger of the two cages moving on the pillars (26) of the inner cage. Energy is transmitted to the element via hooks (19,19') on the outside surfaces of the assembly to which are connected the lines to the sail.

Description

Les fig. I et 2 représentent le même élément piézo électrique destiné < fonctionner
selon les conditions des fig. 4; 5; 6; 7 et 8. On y-voit une surface 5 en continui
té avec un piston 8 qui traverse la surface 6 ou 11 dans la zone axiale 12. L'élémett
de quartz ou de céramique piézo électrique se trouve comprimé par la surface 5 qui se met en contact et appuie sur la céramique ou le quartz 10. Les crochets 1 et 1'
entrainent sous l'action des fils ou chaînes 13 et 13' les surfaces 5 et 6 ou 11.Figs. I and 2 represent the same piezoelectric element intended to operate
according to the conditions of fig. 4; 5; 6; 7 and 8. We see a continuous surface 5
tee with a piston 8 which crosses the surface 6 or 11 in the axial zone 12. The element
of quartz or piezoelectric ceramic is compressed by the surface 5 which comes into contact and presses on the ceramic or quartz 10. The hooks 1 and 1 '
under the action of the wires or chains 13 and 13 ′ drive surfaces 5 and 6 or 11.

Les surfaces 3 et 11 sont solidaires par l'intermédiaire des tiges 4, 4', 4'', et
4 " ' grace aux vis 2, 2', 2" et 2"', (elles peuvent être aussi soudées. La surface 5
est appliquée contre le quartz ou céramique 10 par le ressort 7. Les sils ou chaines 13 et 13' sont mis sous tension soit par l'action des vagues v (fig. 4) passant le long de la bouée B fixée au sol S par l'intermédiaire de 13 et 13' qui agissent sur
EPZ c'est R dire l'élément des fig. 1 ou 2. Un muret 9 et 9' est destiné i arrêter la
course de la surface 5 vers la surface 6 ou 11 lorsque la tension exercée par I et 1' atteint une limite qui risque d'endommager le quartz ou céramique. Dans les fig.9 et
10 (PL.II) les même élément EPZ a été représenté.Mais dans ce cas il s'agit de deux
cages respectivement 20, 23, 22 d'une part et24, 28, 26 d'autre part qui se trouvent
entraînées en sens oppose par l'action des crochets 19 et 19' (gens des flPches) vers
le quartz ou porcelaine 29. Le systeme des deux ca#es permet de loger un plus grand
volume de quartz ou céramique. Des murets 30 sont comme dans le montage précédent destinés n neutraliser l'action des trop hautes pressions.The surfaces 3 and 11 are secured by means of the rods 4, 4 ', 4'', and
4 "'thanks to screws 2, 2', 2" and 2 "'(they can also be welded. Surface 5
is applied against the quartz or ceramic 10 by the spring 7. The sils or chains 13 and 13 'are tensioned either by the action of the waves v (fig. 4) passing along the buoy B fixed to the ground S by 13 and 13 'which act on
EPZ is R to say the element of fig. 1 or 2. A low wall 9 and 9 'is intended to stop the
travel from surface 5 to surface 6 or 11 when the tension exerted by I and 1 'reaches a limit which risks damaging the quartz or ceramic. In fig. 9 and
10 (PL.II) the same EPZ element has been represented, but in this case it is two
cages respectively 20, 23, 22 on the one hand and 24, 28, 26 on the other hand which are located
driven in opposite directions by the action of hooks 19 and 19 '(people of arrows) towards
quartz or porcelain 29. The system of two ca # es allows to accommodate a larger
volume of quartz or ceramic. Walls 30 are as in the previous assembly intended to neutralize the action of excessively high pressures.

Les fig. 3 et 11 représentent des éléments EPZ utilisables pour les systbmes
h pression alternatives tels qu'ils se présentent dans les véhicules. Ainsi EPZ
de la fig. 11 solidaire du capot de# la voiture et lié par l'intermédiaire du crochet ; R la surface 37 n un ammortisseur va appuyer suivant les conditions de pressions
soit sur le qurartz ou céramique 33 soit sur le quartz ou céramique ou cristal 38
et 38'. L'élément EPZ de la tig.3 est destiné < être appliqué entre deux surfaces vibrantes.Figs. 3 and 11 represent EPZ elements usable for systems
h alternative pressures as they appear in vehicles. So EPZ
of fig. 11 secured to the hood of the # car and linked via the hook; R the surface 37 n a damper will press according to the pressure conditions
either on qurartz or ceramic 33 or on quartz or ceramic or crystal 38
and 38 '. The EPZ element in fig. 3 is intended to be applied between two vibrating surfaces.

La fig. 6 représente un élément EZZ tendu par les cordages d'un bateau sous le vent alors que les fig. b et 8 re présentent des éléments EPZ tendus alternativement par
le vent agissant egiesqet sur le drapeau ou la toile rectangulaire ou de toute autre
corme battant sous l'action du vent. Dans la fig. 7 ce sont les branches d'un arbre ou d'un arbuste oscillant sous le vent qui agissent sur l'élément EPZ.Fig. 6 shows an EZZ element stretched by the ropes of a leeward boat while FIGS. b and 8 re present EPZ elements stretched alternately by
the wind acting egiesqet on the flag or the rectangular canvas or any other
corm beating under the action of the wind. In fig. 7 it is the branches of a tree or shrub oscillating in the wind which act on the element EPZ.

Dans le cas des véhicules l'élément EPZ servira a actionner une dynamo ou un alter
nateur ou n recharger une batterie.In the case of vehicles the EPZ element will be used to activate a dynamo or an alter
nator or charge a battery.

Les différents montages proposés utilisent la piezo électricité pour obtenir de l'é
nergie ' partir des vagues où du vent et pour réaliser des économies d'énergies
dans le cas des véhicules.The different assemblies offered use piezoelectricity to obtain energy.
energy from waves or wind and to save energy
in the case of vehicles.

La bouée B de la fig.4 peut être un pneumatique gonflable, donc facile < transporter. Buoy B in fig.4 can be an inflatable tire, so easy to transport.

Tous ces éléments sont isolés des actions extérieures par une enveloppe plastique
en accordéon. All these elements are isolated from external actions by a plastic envelope
accordion.
