Title: Nuclear reactor fuel element design - esp. a head for fuel rod assembly of a sodium cooled fast neutron reactor
Inventor: GARCHON BERNARD
IPC: G21C3/324
Filed: 1975-04-03
Abstract: In a nuclear reactor fuel element assembly, particularly a sodium-cooled, fast neutron reactor, containing some assemblies of fuel elements containing both fissile and fertile material, each assembly has a standard head which is the same for all assemblies. Each heat is mounted on the axial extension of the upper part of a polygonal and especially a hexagonal, elongated hollow casing forming the body of the assemblage. The head consists of a cylindrical sleeve, terminating in a conical bearing and has an internal circular opening for gripping the assembly. The cylindrical sleeve has a roughened external surface, which has a constant reflecting power with respect to ultrasonic radiation. Ensures that all the fuel elements are at the same level for gripping by the remote control unit. A single type of head facilitates manufacture and the geometry of the head avoids damage during changing the core of the spherical sealing bearing at the lower end of the casing of the assembly and its locating foot. Finally, any assembly which is out of position can be detected by the usual ultrasonic methods and the transverse holes through the head in this case ensure that it is cooled by natural convection.

Title: Trigger generator circuit for controlled rectifier - is designed to use logic techniques to control timing of gate voltage and includes opto electric diode
Inventor: NOLLACE PIERRE
IPC: H02M1/096
Filed: 1975-04-22
Abstract: A control and trigger circuit is used for gate controlled rectifiers, particularly those used in oscillators where the triggering level and timing are a function of the load state. The input trigger is fed to the circuit via an optoelectronic diode-transistor pair (12, 17). The output of which provides one input to an AND gate. The second input is derived from a comparator. The two inputs to this are a reference level and a voltage which is a function of that across the controlled rectifier. The rectifier trigger electrode is driven from the logic output via an emitter follower and current limiting resistor and is itself shunted by a series chain of a resistor, diode and capacitor.
Patent FR-2310934-A1 (FR)
Title: Reinforced laminated adhesive paper tapes for binding boxes - with impermeable adhesive interlayer to facilitate stripping the tape
Inventor: BERGE CHARLES
IPC: C09J7/21
Filed: 1975-05-16
Abstract: Multilayer adhesive coated paper tapes incorporating a layer of fibrous reinforcement in a matrix of bonding material, where the adhesive matrix is isolated from the paper layer supporting the external adhesive coating by an interfacial adhesive which is impermeable to the matrix adhesive. Tapes can be used esp. for strapping cardboard cartons, where the tapes are subsequently to be partly manually to release the package. The impermeable coating prevents the matrix binder from permeating the substrate layers and making it too difficult to peel off the reinforcing layer so that the substrate paper can readily be broken by hand. Clean sepn. of the reinforcing layer allows boxes to be opened without excess force and damage, permitting reuse of the boxes.
