Title: Selektivni kontrolnik izolovanosti
Inventor: SAVO JELIC
Filed: 1993-01-12
Abstract: SELEKTIVNI KONTROLNIK IZOLOVANOSTI, se primenjuje u zemljospojnoj zaštiti električnih mreža i uredjaja. Pored preventivnog karaktera zaštite (signalizacija, pa pri daljem slabljenu odnosno zemljospoju isključenje), kontrolnik omogućuje selektivnu kontrolu pojedinih otcepa što je posebno značajno kod naizmeničnih mreža sa izolovanim zvezdištem. Uz ovu novinu selektivni kontrolnik izolovanosti unosi i drugu pogodnost: razdvajanje kapacitivnih od rezistivnih komponenti struja zemljospoja. Ove i druge karakteristike se postižu tako što se izmedju mreže koja se štiti i zemlje uključuje generator (G) malog napona i niske učestanosti, a oko odvodnih kablova svakog otcepa se postavljaju obuhvatni transfor-matori (T) kroz koje, pored ostalih, teku i struje zemljospoja. Struja sekundara ovih transformatora se u elektronskim kolima, kako je to prikazano na slikama 1. i 2, pretvara u napon, zatim filtrira tako da se dalje, u polutalasni ispravljač te merna i okidna kola vodi samo komponenta niske učestanosti koja potiče od našeg niskonaponskog generatora. Razdvajanje kapacitevne od rezistivne komponente struje zemljospoja vrši se merenjem prolaska kroz nulu napona generatora (G) i struje zemljospoja i evaluacijom njihove razlike za mikroračunarsko odredjivanje koeficijenata sa kojima se množi struja zemljospoja.

Title: Load Transporting Carriages or Travellers for Overhead Tracks.
Inventor: MATTHEWS JAMES
IPC: B66C21/00
Filed: 1917-01-03
Abstract: 112,311. Matthews, J. Tan. 3, 1917. Overhead travellers.-The trolly of a load-transporter is automatically freed from the track stop for the inward journey by means which are unattached to the loadsupporting hook but co-operate therewith to sustain the load when raised; and on commencing the return journey, the trolly is similarly released from the track stop, but the hook is locked to sustain the load by supplementary means. The trolly 6 is supported on rollers 7 running on a track 2 to which are clamped stops 28, 32 co-operating at the ends of the travel with catches 27, 29 pivoted at opposite ends of the trolly. The hauling-rope 9 is attached to the trolly and passes through a fall-block 10 and over a guide-sheave 11 to the winding-drum. The catches 27, 29 are coupled together by links 33, and the catch 29 is weighted so that it tends to disengage from the stop 32 and to move a sliding bolt 37 to the left. A hook 16 is pivotally mounted on the trolly and is weighted so that it normally assumes the position shown in Fig. 2 with a shoulder 45 engaging the bolt 37. When the load is raised, a pin 14 on the fall-block 10 tilts the hook 16 until the bolt 37, influenced by the weight of the catch 29, slides over a shoulder 40 on the hook which then supports the load. Further hauling on the rope 9 transports the trolly 6 to the left until the stop 28 engages a finger 42 which is connected by a flexible elastic member 19 to a counterweighted pawl 20. This pawl is rocked towards a shoulder 18 on the hook, but is kept out of engagement therewith by a counterweighted guard 25. After engaging the finger 42, the stop swings down the catch 27 to lock the trolly, and the links 33 withdraw the bolt 37 so that the hook 16 is free and the load can be lowered. When the load is again raised, the hook 16 is rocked as before and a lug 48 thereon engages the guard 25 and removes it from the point of the pawl so that the pawl engages the shoulder 18 on the hook and sustains the load. To return the trolly, the rope 9 is paid out and the initial movement of the carriage tilts the catch 27 upwards about its pivot 26 and the consequent movement of the links 33 slides the bolt 37 into locking position above the shoulder 40 on the hook 16, and simultaneously removes the pawl 18 by a pin 49 engaging the weighted arm 22 of the pawl. As the trolly reaches the right-hand stop 32, the catch 29 engages the stop and is raised into the locking position, thereby disengaging the bolt 37 and allowing the load to be lowered. As the hook moves into the position shown in Fig. 2, the pawl guard 25 swings under gravity to its original position. The track 2 preferably inclines downwardly towards the stop 32; otherwise a tail rope is used for effecting the right-hand traverse of the trolly.
