Title: Spent fuel rod sectioning apparatus - for recovery of fissionable or fertile nuclear fuel
IPC: G21C19/36
Filed: 1974-01-11
Abstract: Sectioning of rods of tubes in a bundle particularly a bundle of nuclear fuel elements, comprises first removing the tubes from the bundle, at least one then being advanced step-wise but being clamped and immobilised between the advancing strokes during which time a section is sheared off. Pref. after release from its bundle the fuel rods are brought into contact with each other to form at least one layer and while clamped and immobilised are sectioned in small number groups e.g. 1-5, by a cutting tool moving almost perpendicularly to the plane of the layer. In contrast to the known sectioning units in which a complete bundle is sectioned by a guillotine, a rotary cutter may be used which is small and easily introduced through the biological shield of the cell in which they are sectioned and in which the sections are subsequently dissolved. Problems associated with the elasticity of a bed of a large number of previously cut sections are avoided.

Title: Irreversible shaft coupling for aircraft flaps - has spring loaded brake piece and inclined coupling ball runs
Inventor: BELLIERE PIERRE ALFRED
IPC: F16B1/04
Filed: 1974-04-09
Abstract: An annular braking piece forming part of the driven rotating shaft can move axially with respect to the shaft and bears against an annular transverse face forming part of the housing, under the action of spring washers. It also bears against alternate opposite step helical ramps arranged in two groups and forming part of the driving shaft and the annular braking piece. The ramps of a group press against the ramps of the other group by means of bearings, so that at rest the driven shaft is blocked from rotating in both senses by the braking piece which is held against the annular fixed face. A couple of the driving shafts, in one sense or the other, produces via the helical ramps a backward axial movement of the braking piece then a rotation of this piece, and the driven shaft.

Patent FR-2258279-A1 (FR)
IPC: B60G15/06
Filed: 1975-01-13
Abstract: In order to prevent lateral road forces from acting on the rear wheels (11, 12) of a motor vehicle when cornering, in the suspension the central bearing (46) for a rigid rocker arm (39) is of elastic construction. The radius arms (40, 41), which are pivoted on the vehicle body (34, 35) are supported by their other ends on the rocker arm (39). The radius arms (40, 41) - as seen in plan view - run obliquely to the direction of travel, directed outwards from their pivot point on the rocker arm (39). In plan view the rocker arm (39) with the laterally arranged radius arms (40, 41) forms a trapezium. Owing to the elastic flexibility both in the central bearing (46) and in the cross member bearing (32, 33) a certain lateral offset of the radius arms (40, 41) is possible. The rocker arm (39) is thereby rotated out of the curve when cornering by the road forces acting in a transverse direction, resulting in understeer.

Patent FR-2289121-A1 (FR)
Title: Protein-protected feedstuffs for ruminants - by mixing protein-contng. materials with silicic acid and formalin
IPC: A23K40/35
Filed: 1975-10-29
Abstract: Protein-based feedstuffs are protected against bacterial desamination by reacting the proteins with short-chain aliphatic aldehydes or aldehyde-formers to form a surface layer which protects them against decomposition in the paunch of ruminants. The larger part of the proteins in the feedstuffs is not chemically changed in the paunch of ruminants so that more amino-acids are available for growth. The process is economical as it does not require long drying times. The proteins are adequately protected by a surface layer but are not changed chemically. The higher availability of amino-acids recycles more urea to the paunch via the ruminohepatic circulation to aid bacterial growth.
