Patent FR-2314560-A1 (FR)
Title: Light water reactor immersed in water filled basin - has inlet from basin opened automatically to provide emergency cooling
Inventor: HANNERZ KARE
IPC: G21C1/14
Filed: 1976-06-10
Abstract: A reactor plant comprises a light water reactor with vertical fuel element clusters, connected via inlet and outlet chambers and a prim. ducting circuit with a heat exchanger and a circulating pump; the reactor is contained in a reactor vessel immersed in a water-filled basin; in normal operation, the water of the prim. circuit is isolated from that of the basin by a normally closed communication which can be opened. This communication consists of an outlet and an inlet in the walls of the prim. circuit, both of which are in permanent, open communication with the basis, the outlet being in the form of a gas trap, e.g. an inverted U-pipe; the inlet may also be in the form of an inverted U-pipe gas trap. Pref. the outlet gas trap is the higher, its open end being above the top of the reactor core and the inlet gas trap is lower, with its highest part at a lower level than the open end of the higher gas trap. A typical application is for a district heating system, the water in the basin being used as a heat sink for emergency cooling. The arrangement shown, where the gas traps are used instead of valves, eliminates the possible mechanical failure of valves and thus improves safety.

Title: Valve for particulate material plastics sack - has additional plastic foil layer incorporated around valve opening in one piece sheet
IPC: B65D30/24
Filed: 1976-07-02
Abstract: The length of material is folded and joined to form a sack with one wall with overlapping end parts. The end of the sack are closed and the overlapping end parts joined together by a longitudinal binding seam which is interrupted to form an opening for the sack valve. Each side of the valve opening has a cross seam which joins together the overlapping end parts of the longitudinal seam and which together form a filing valve between the overlapping end parts. The layers of the plastic foil in the overlapping end parts include in the region of the valve at least one additional layer of plastic foil. The additional layer of the plastic foil is joined with the overlapping layers of the end parts by the cross seams.

Patent FR-2362691-A1 (FR)
Title: Insulating or exothermic covering powder contg. cellulose fibres - has greater voids content and reduced apparent density
Inventor: NOUVEAU MARC
IPC: B22D27/06
Filed: 1976-08-27
Abstract: An insulating or exothermic covering powder to slow down the rate of solidification of the upper part of a melt contains 1-20 pref. (5-10)% natural cellulose fibres which show a high degree of individualisation, either sepd. or joined in gps. of a few units in the form of a pellet of intermixed fibres of very small dia. (granulated fibres). The apparent density of the powders is reduced by increasing the percentage of voids with the fibrous material. Thus if a crust should form on the top of the solidifying melt it has a high porosity and the insulating properties and/or the exothermic reactions are maintained.

Title: Rectangular package formed from single sheet - has grip tongue reinforced by flaps extending sideways from fold lines
Inventor: LAZERAND JEAN
IPC: B65D5/462

Patent FR-2395072-A1 (FR)
Title: Wet sand grader unit - has surplus water outlet on rotary drum end with graded sand discharge on other
IPC: B28C7/00
Filed: 1977-06-21
Abstract: In the grading unit fine fraction of sand is freed from impinging impurities and graded sand can be discharged at several points of the unit. The water sand mixt. is fed into the rotating drum (1) through inlet tube (2) which has an increasing dia. in direction of the water flow. By this arrangement the flow velocity of the water is gradually decreased, so that by the time the water reaches the end of the tube its velocity is very low and it trickles evenly distributed into the water level already present inside the drum through the perforated part (5) of the tube. As the water and sand slides gently into the water content of the drum, the spiral channels formed by the numerous guide blades (7) enable the sand to settle in these channels. By the rotation of the drum the sand is steadily shifted towards the other end of the drum, where it comes within operating range of the two sets of rotating wings (8, 8) which scoop up sand particles on their surfaces while the water drops back into the drum. As the wings rotate sand deposited on any wing reaching its top dead centre drops its deposit onto the conical discharge surface (10, 10) from where it is disposed of via chute (17).

Title: Slicing smoked salmon - using fully automated machine with synchronised feeding and slicing action
IPC: B26D7/06
Filed: 1977-06-29
Abstract: A fillet of smoked salmon is laid upon a support plate which is inclined quite steeply to the horizontal. The longitudinal axis of the fillet lies in a vertical plane and the support plate complete with fillet is reciprocated vertically. The lower end of the fillet overhangs the support plate so that an upstroke of the plate brings the overhang across the cutting edge of a rotary blade. The slice thus detached is delivered by gravity on to a horizontal collecting table. Before the next upstroke, the fillet is allowed to slide down the support plate to present a new overhang for slicing. The extent of the new overhang is pref. limited by a stop plate just below the rotary blade. The upstroke pref. carries the slice over the top of the top plate to drop onto the collecting table. Support plate reciprocation is pref. synchronised with fillet feed release for fully automatic operation. The machine offers high output of slices for commercial distribution. The quality of prod. is at least equal to manual slicing, but the cost is greatly reduced.

Title: High tensile strength optical waveguide - has two layer optical fibre with outer metal covering used for transmitting electrical signal
IPC: H01B11/22
Filed: 1977-08-29
Abstract: The waveguide has a glass core (11) having a first refractive index. It has a concentric glass covering (12) around the core. This has a refractive index lower than the value of the first. This second value is at least 0.1% lower in order to ensure total internal reflection of the radiations at the interface between core and conver. The waveguide has a malleable metal covering (13), over the outer glass layer (12), which provides the mechanical strength required of the waveguide, without hindering the optical properties. It may be used for simultaneous transmission of electric signals. A final plastic layer is extruded over the metal covering. The outer glass cover is 10-100 microns thick while the metal layer is 5-100 microns thick, making a total diameter of less than 300 microns.
