Title: Nuclear reactor fuel assembly - with elements spaced by helical fins arranged to reduce coolant flow around outer elements
IPC: G21C3/338
Filed: 1974-08-08
Abstract: A nuclear fuel sub-assembly comprises a bundle of elements in a hexagonal wrapper. The elements are spaced apart and from the wrapper by helically wound fins of uniform radial height. Fins on an outer row of elements are wound at half the pitch of those on inner elements, and alternate outer elements are wound opposite hand. Outer and intermediate elements are oriented so as to nest together. The arrangement is for use in a sodium-cooled fast reactor. The half pitch windings provide more lateral support points for the outer elements, and the increased flow resistance reduces over-cooling of the outer elements.

Title: Key operated calculating machine element - uses perforated driving band to translate key depressions into addition subtraction and printing
IPC: G06C15/04
Filed: 1975-01-13
Abstract: Depression of the calculating machine key actuates a toothed wheel, the number of the teeth being equal to the number of the key. This moves the perforated band through a proportional distance to the right. Each perforation engaging the toothed wheel rotates it through one ninth of a revolution. The axle carries three threaded sleeves, the first of which moves the calculator band by engaging the bevelled strip against the numbered trapezoidal section of the band. The second sleeve operates in reverse for subtractions, and the third operates the printing mechanism.

Title: Induction furnace for metal melting - using thinner refractory around lower part which is heated by induction
Inventor: ANTOINE JACQUES
IPC: C21C5/56
Filed: 1975-01-20
Abstract: Method of continuous melting of products rich in metallic iron esp. pred-reduced products is claimed in which a mass of metal is kept molten in a container while generating induced electric current in the lower part of the container to stir and heat the metal, the stirring being applied to a region of the bath limited to the lower part of the container. Wear on the refractory lining is reduced since the most penetrating wear is effected at the contact region between metal refractory and reaction gas (if any) or air, when this region is in movement during agitation, and this region, is not stirred by the magnetic action. Improved yield per unit power can be obtd. by using a thinner refractory lining in the region where the induction is applied.

Title: Static radiating panel for mortuary slab - to prevent condensn. and frost around edges and base
IPC: F25D21/04
Filed: 1975-01-30
Abstract: Cold mortuary table, for the preservation of human remains by means of a mobile, self-contg. freezing unit, has a radiating condenser which is placed under the slab in order to avoid the formation of frost and condensn. in the unused zones around the corpse. The radiating panel is sepd. from the metallic plate by an insulator; it is in contact with the plate at certain points, transmitting its heat to specified zones of the plate. The evapn. coil is located beneath the corpse. The radiant panel is associated with a coil and a compressor. When the appts. is in operation, an equilibrium zone is established between the radiating panel and the expansion coil by the conductivity of the metallic plate. Some of the heat rejected by the refrigeration unit is transmitted to the edges and the unused portions of the slab; this prevents condensn. and the formation of frost. Only the area in contact with the corpse is frozen to preserve it from decomposition.

Title: Diverter for granular prod. flowing through rectangular passage - to divide, divert or sample cereals etc. without waste
IPC: G01N1/20
Filed: 1976-03-04
Abstract: The diverter takes the form of a rectangular plate pivoted on an axis at right angles to the axis of the passage when the plate is in its non-diverting position, it fills a rectangular aperture which extends across the full width of one side of the passage. When the plate is pivoted, its upstream edge moves across the stream of flowing granules to approach the far side of the passage. the upstream face of the plate leads diverted granules into an integral duct which leads off from the aperture. In its fully pivoted position, the plates upstream edge seals against the far wall of the passage and a flange on the duct seals against the near wall on the outside of the aperture. Prods. mentioned include cereals, medical granules, animal feed, dosed additives. Transition pieces can couple the diverter into passages which are not of rectangular cross-section. The diverter is hand operated and does not require an expensive screw mechanism. The duct ensures that all diverted prod. is delivered as required without waste.

Title: X-ray film casette with contrast enhancement - having film pressed flat between phosphor layers using elastic padding
Inventor: STOFF GERHARD
IPC: G03B42/04
Filed: 1976-03-24
Abstract: The contrast of the X-ray exposure is enhanced, and the amount of radiation exposure reduced, by sandwiching the X-ray emulsion between two phosphor layers, in a special cassette. The cassette has a back plate (5) coated with one phosphor (6) while the other half of the cassette has a padded filling (7) coated with the second phosphor (9). The padded filling ensures an even pressure over the film and intimate contact between the phosphor layers and the film, to prevent loss of contrast and resolution. For improved life the phosphor material is mixed with a hard resin binder. This eliminates any protective coating layer and improves the contrast even further.
