Abstract: Kada je primarni klip (3') u krajnjem levom položaju sekundarni klip (3) je u krajnjem donjem položaju, a samim tim i osovina (4) koja je fiksirana za klip (3) nalazi se u samom centru primajućeg zupčanika (1). Ovo je položaj praznog hoda reduktora gde se ulazni, primajući zupčanik (1) okreće, a poluge (5), zupčaste letve (6) i zupčanici (7), zupčanici (9) i (10) miruju. Pritiskom na klip (3') posredstvom hidrauličnog ulja pomera se klip (3), sa njim osovina (4), poluge (5), zupčaste letve (6) pri čemu pomeranje ozubljenih letvi (6) zavisi od mesta ekscentra na poluprečniku zupčanika (1). (pod ekscentrom se podrazumeva osovina (4)). Pomeranje zupčastih letvi uzrokuje pomeranje zupčanika (7) uzupčanih u zupce zupč. letvi (6), a kako su na osovinama tih zupčanika (7) učvršćeni ispravljači (8) okretanja promenljivog smera (za slobodan hod), oni daju jednosmerno kružno kretanje na zupčanicima (9) i dalje na izlaznom zupčaniku (10). Osnovna namena reduktora je upotreba u drumskim i železničkim vozilima kao zamena za postojeće manuelne i automatske menjače stepena prenosa koji nemaju kontinualnu već skokovitu promenu prenosnog odnosa, nemaju mogućnost pokretaja transmisije od nultog obrtaja što iziskuje upotrebu kvačila.

Title: Fibre=optic leak detection probe for fluids in pipes - has logic analyser connected to fibre to measure modification of photon flux caused by fluid leak actuated blocker
IPC: F17D5/02
Filed: 1983-09-16
Abstract: The pipe of interest is surrounded by a concentric sealed sheath divided into sections whose length depends on the accuracy with which it is desired to pin-point the leak. In the case of a leak there will be a circulation of product between the pipe wall and the sheath wall in that section. Each section is connected to a probe by an admission - return pipe. The probe is crossed by an optical fibre interrupted at its centre and connected to an electronic system operating peripheral equipment such as alarms and stop-values. - The leak is detected by the modification of the signal injected into the optical fibre. This modification arises due to the dissolution of a degradable support of a ball which then blocks, due to gravity, the passage of luminous flux. The optical signal modification may also be achieved by modification of the refractive index or opacity of the product crossing the detector. The output signal is analysed by logic circuits and amplified to excite an electronic valve connected to the various peripherals. The system is insensitive to electrical fields and presents no danger of fire or explosion.(0/1)

Inventor: PRESENTEY SHELLEY M
IPC: G11B15/46

Granted: 1979-08-28
Abstract: ABSTRACT OF THE DISCLOSURE            A magnetic tape recorder wherein the magnetic head is rigid-ly secured to two spaced-apart platens of a rigid frame.  The platens are rigid with several distancing elements and further carry bear-ings for a capstan shaft and for a pivotable pressure roller which biases magnetic tape against the capstan shaft.  The rigid frame prevents the magnetic head from vibrating independently of the capstan shaft and/or pressure roller to thus reduce or eliminate wow and flutter by preventing that portion of the tape which engages the head from vibrating relative to that tape portion which is pinched between the capstan shaft and the roller.
