Prezenta inventie se refera la un procedeu de recuperare a zaharului din melasa prin tratarea zemii predefecate cu acid acetic. Se reduce continutul de substante melasigene si, prin aceasta, procentul de zahar care ramâne în melasa; prin reducerea pierderilor de zahar în melasa creste randamentul de extractie.

Inventia se refera la o doza de derivatie, alcatuita dintr-o cutie paralelipipedica, în care se monteaza niste bucse metalice pentru ficarea unor piese de contact asamblate cu ajutorul unor suruburi, niste piulite speciale care strâng cablul în stutprintr-o garnitura, un capac si o alta garnitura.

Inventia are ca obiect un dispozitiv electronic de comanda si actionare destinat sa functioneze în cadrul cofreteor antigrizutoase din nivele subterane, în scopul eliminarii fenomenului de arc electric care poate sa apara la contactele elementelor de executie. Dispozitivul este constituit din doi tiristori conectati în paralel cu contactul normal deschis al contactului de comanda, iar bobina acest...

Inventia se refera la un generator de aeroioni destinat tratamentului unor afectiuni ale urechii externe. în acest scop, generatorul este alcatuit dintr-o sursa de înalta tensiune continua, cu doua canale de iesire independente racordate la câte un electrod de emisie tip casca, care contine niste siruri de electrozi legati la o sursa de înalta tensiune.

A submerged square nuclear fuel assembly is locked and held by a device including a support on which the legs of the assembly rest. A square rotatable plate is located on the support between the legs, and can be rotated by a remote actuator. Each corner of the plate has a notch formed in it. When the plate is turned, the notches engage the legs of the assembly to lock it in position. The device...

The core of a pressurised under water nuclear reactor has a cylindrical casing which supports internal partitions surrounding the fuel rod assemblies. Some of the partitions are joined together by bolts with screw threads; and leaks can occur at these joints. When a leak occurs, the reactor is stopped, and a mobile robot box is aligned on the leaking joint. The box contains a turret which can b...

A burnable poison rod (10) for use in a nuclear fuel assembly has two concentric tubes. Neutron absorbing pellets (24) are located in the annular space between the tubes. The space is sealed by end plugs. A retaining device for the pellet stack bears against the end pellet. The device includes C-shape springs with circumferentially spaced radial projections. The projections are urged against o...

A trip system for control and shutdown of a nuclear reactor is presented in which the reactor and the components cooperating with it operate according to a number of processes each having 1 or more controlling parameters. The system for control and shutdown comprises a first device connected to the reactor, which shuts down the reactor when working, an array of similar probes for controlling each...

The assembly includes an upper shield provided with a lifting tripod which can be attached to a crane. Below the shield is a cooling casing fitted with cooling fans and surrounding devices moving tongs altering the position of control rods in the reactor core. Below the casing is the reactor head or roof, which is located on the reactor vessel, and is anchored by tie rods to the shield. The cas...
