Patent FR-2383506-A1 (FR)
Title: Neutron guide for conducting neutrons to experimental zone - is formed by two plates fixed by adhesive to two bars and incorporates clearances to receive adhesive, maximising precision of assembly
Inventor: POUSSOU JACQUES
IPC: G21K1/02
Filed: 1977-02-25
Abstract: An element of a neutron guide consists of two bars and two plates. The lateral parts of the internal surfaces of the plates are fixed to the bars by an adhesive. The internal surfaces of the bars are polished. Clearances to receive the adhesive are made in the lateral prats and the bars are in contact with the internal faces of the plates beyond these clearances, fixing the sepn. of the plates. Problems associated with establishing the conditions required for high energy efficiency, energy selection and operator protection are eliminated. These conditions require that the parts of each element have precise dimensions and fixed relative positions. The dimensional tolerances are of the order of a hundredth of a mm. and the angular tolerances between successive elements are 10-20 seconds of arc. Loss of neutrons is prevented and pollution by dust is minimised. In existing equipment, by contrast, the precision is conditioned by that which can be obtd. during adhesion, requiring rigorous control of the thickness of the layer of adhesive.
Patent FR-2384292-A1 (FR)
Title: Shaft position servo-control circuit - employs integral channel to decrease delay when demanded value changes rapidly
Inventor: BENEJEAN RICHARD
IPC: G05B13/02
Filed: 1977-03-15
Abstract: An integration circuit is used to integrate the error signal in a control regulator controlling position of a shaft. This technique decreases delay in achieving the demanded value when the demanded value changes rapidly. The position of a motor shaft is detected and added algebraically with a demanded value. Two unit gain amplifiers comprise a proportional channel while an integrator forms an integral channel. The integrator is blocked by a signal derived from a speed sensor and the error signal in a blocking decision circuit. The two channel signals are added to provide a control signal for motor power supply circuit.

Patent FR-2371643-A1 (FR)
IPC: F28F21/08
Filed: 1977-11-22
Abstract: In the radiator, vertical heating pipes (1) have, on two longitudinal sides lying diametrically opposite in cross-section, in each case a conical groove, into which the angled edges of the covering sheets (2) are clamped securely by means of a press wedge (3). An upper and a lower manifold (4) are inserted in each case through a passage hole on the two ends of each heating pipe.
