Title: Quick fitting insulation for tubes - rolled metal outer case forms mould for rigid polyurethane foam insulation
IPC: F16L59/10
Filed: 1973-06-22

Title: Convergent solar energy collector - presents planes of reflectors constantly at right angles to incident solar radiation
IPC: F24S23/77
Filed: 1975-01-17
Abstract: A convergent device for collecting and using solar energy comprises an arrangement of mirrors, fixed in its geometry, but capable of being oriented in all directions. The mirrors are stabilised according to angles calculated to give a convergence of the incident solar radiation. The device precisely follows the apparent motion of the sun and presentsits surface place constantly at right angles to the solar radiation. The stable position of each reflector is calculated to receive the radiation in such a way that the angle of reflection equals the angle of incidence. The reflected radiation becomes incidental radiation on the surface of a counter-reflector which reflects it towards the focus of convergence at a point beneath the base of the device, around a point on the axis perpendicular to its plane. The stable arrangement of the reflectors and the counter-reflectors is the same on all the secant planes. The geometrical arrangement of the plan of the device is arbitrary and may be a polygon or a circle. Appts. gives a yield, relatively to the amt. of surface exposed, much higher than those of existing devices. The only limiting factor is the amount of sunshine of the locality and the device can be installed anywhere provided there is sufficient sunshine, whether there is wind or not and irrespective of the terrain or location (on roof, etc).

Title: Nuclear reactor cooled by liquid metal - has exchangers and inner vessel joined at toric surfaces to distribute stresses
Inventor: CHEVALLIER RENE
IPC: G21C1/03
Filed: 1975-12-29
Abstract: A nuclear reactor cooled by a liq. metal, e.g. sodium, has the sodium contained in a principal vessel sepd. into two parts one hot and one cold. Sepn. is by a metal wall forming an inner vessel, which contains the core and the hot metal. The inner vessel consists of upper and lower cylindrical parts of diameters about equal to those of the principal vessel and of the core respectively, connected by a conical part. The inner vessel and the cylindrical enclosures are given a shape constituted by a surface of revolution generated by an arc, at the place where the sodium feed holes are located, either over their whole circumferences, or locally. The cylindrical enclosures are attached to the inner vessel at this place by an element of toric form, concave outwards. Thermal protection of the inner vessel and the cylindrical enclosures is provided by walls. This method of direct connection of the enclosures of the inner vessel without intermediate piping, gives good distribution of the stresses caused by the weight of the enclosures.
