INVENŢII<br />
g<strong>in</strong>e (variants)<br />
(57) The <strong>in</strong>vention relates to the mechanical engi-<br />
neer<strong>in</strong>g, <strong>in</strong> particular to the motor eng<strong>in</strong>eer<strong>in</strong>g,<br />
namely to the <strong>in</strong>take mufflers, ma<strong>in</strong>ly of the <strong>in</strong>-<br />
ternal combustion eng<strong>in</strong>es.<br />
Summary of the <strong>in</strong>vention consists <strong>in</strong> that the<br />
<strong>in</strong>take muffler of the <strong>in</strong>ternal combustion en-<br />
g<strong>in</strong>e, accord<strong>in</strong>g to the first variant, conta<strong>in</strong>s a<br />
body with <strong>in</strong>let and outlet pipes and a porous<br />
sound absorber, which is made of metal-fi-<br />
brous material and it is placed <strong>in</strong>to the body<br />
form<strong>in</strong>g an axial gas-supply channel of variable<br />
section.<br />
Accord<strong>in</strong>g to the second variant, the <strong>in</strong>take<br />
muffler of the <strong>in</strong>ternal combustion eng<strong>in</strong>e con-<br />
ta<strong>in</strong>s a body, the wall of which is made double<br />
and <strong>in</strong>cludes the outer and perforated <strong>in</strong>ner<br />
cas<strong>in</strong>gs. The outer cas<strong>in</strong>g may be made de-<br />
mountable and partially perforated.<br />
The axial gas-supply channel of the <strong>in</strong>take<br />
mufflers accord<strong>in</strong>g to both variants may be<br />
made cyl<strong>in</strong>drical with annular prom<strong>in</strong>ences of<br />
the same height or different height: decreas-<br />
<strong>in</strong>g towards the outlet pipe.<br />
The axial gas-supply channel may be made<br />
conic: of confuser type or diffuser-confuser<br />
type.<br />
The result of the <strong>in</strong>vention is a high gas energy<br />
dissipation, condition<strong>in</strong>g the efficient attenua-<br />
tion of the sound vibrations.<br />

(54) Electrohydrodynamic w<strong>in</strong>d plant<br />
(57) The <strong>in</strong>vention relates to the power eng<strong>in</strong>eer-<br />
<strong>in</strong>g field, <strong>in</strong> particular to the w<strong>in</strong>d plants for elec-<br />
tric power production.<br />
The plant consists of an aerosol charged gene-<br />
rator, <strong>in</strong>clud<strong>in</strong>g a liquid atomizer and an<br />
electrocharg<strong>in</strong>g system, of a collector and a<br />
load connection scheme. The aerosol charged<br />
generator is placed onto an isolat<strong>in</strong>g support,<br />
and <strong>in</strong> the capacity of collector is used the earth.<br />

(54) Lentilă cu <strong>in</strong>dice de refracţie gradat<br />
(57) Invenţia se referă la domeniul optoelectronicii<br />
şi poate fi utilizată în sistemele de transmitere<br />
a <strong>in</strong>formaţiei pr<strong>in</strong> fibre optice şi în sistemele<br />
de înregistrare-citire a <strong>in</strong>formaţiei pr<strong>in</strong> <strong>in</strong>ter-<br />
mediul purtătoarei optice.<br />
Esenţa <strong>in</strong>venţiei constă în aceea că lentila cu<br />
<strong>in</strong>dice de refracţie gradat conţ<strong>in</strong>e un înveliş de<br />
protecţie contra lum<strong>in</strong>ii cu miez, amplasat co-<br />
axial înăuntrul unei bob<strong>in</strong>e de <strong>in</strong>ductanţă.<br />
Totodată învelişul este executat ca un tub d<strong>in</strong><br />
masă plastică, iar miezul este executat ca o<br />
suspensie coloidală de praf Y 3 Fe 5 O 12 în ulei de<br />
polietilsiloxan.<br />
