Title: Wave soldering apparatus
IPC: B23K3/06
Filed: 1964-06-16
Abstract: 1,058,475. Soldering. ELECTROVERT MANUFACTURING CO. Ltd. June 16, 1964 [Oct. 30, 1963], No. 24964/64. Heading BAR. Wave soldering apparatus comprises a tank 10, Figs. 2, 4 and 5 (not shown), containing molten solder (30) and divided, as by a partition (14), into a supply section (36) and a return section (37), a pump (9) for pumping molten solder from section (37) to section (36), a solder discharge nozzle (45) communicating with section (36) and providing a wave of solder overflowing into section (37), and a reservoir (50) of liquid additive having its liquid surface substantially level with the nozzle exit so that the solder wave (35) draws a film of additive from the reservoir. In an embodiment for soldering components to circuit boards fed over a support (55) and between guide plates (41) forming the ends of the nozzle (45), the additive is an oil which rises into the reservoir (50) from a supply opening (60) beneath the surface of the solder. The oil supply is regulated by a pump, release valve and an adjustable micrometer valve (Fig. 5). The reservoir (50) comprises a parallel channel following the top surface of the nozzle, which has a notch (56) through which the oil is drawn by the solder wave. The nozzle (45) is at the top of a riser (17) connected to the lower section (36). A fence (68) adjacent an oil drainhole (67) prevents the oil from approaching the pump impeller, which acts in an opening in the partition (14). The discharged oil is not recirculated. Electric resistance heaters (15) are located in the lower section (15), and the tank is supported by an outer casing (22).

Title: Improvements relating to nuclear reactors
Inventor: JACKSON GEORGE OLIVER
IPC: G21C1/02
Filed: 1965-06-15
Abstract: 1,106,256. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 3 June, 1966 [15 June, 1965], No. 25318/65. Heading G6C. A nuclear reactor core is composed of closely packed fuel elements, each of the elements in each of several groups being supported in such manner as to tend to tilt the element towards the centre of the respective group, whereby the elements of each group are urged laterally into firm engagement either with one another or with a structural member around which the group may be arranged. It is convenient to use structural members which are required in the core in other roles, e.g. guide tubes in which control rods are insertable. The location of the fuel elements in groups results in the cumulative effect of thermally-induced stresses being avoided. With cantilever supported elements having an unfuelled length adjacent the supported end, it is preferred that the engagement portions only in the region where the fuelled and unfuelled lengths adjoin so as not to interfere with the freedom of the elements to splay in the event of a radial temperature gradient in the core tending to bow the elements convexly inwards. In the case of a core support having sockets in which to receive the fuel elements, the tilting tendency may be produced by each fuel element having a pair of bearing surfaces co-operating with a pair of bearing surfaces in the corresponding socket, there being slight misalignment of the surfaces of one of the bearing surface pairs. Preferably the misalignment is in the bearing surfaces of the sockets. Where the reverse is the case, the fuel elements are each provided with an end fitting including a bearing bush carried eccentrically of the element by a bending bar, there being also a bearing surface concentric with the element so that when the eccentric bush and the concentric surface are located in a socket the bar is bent to impose a tilting tendency on the element. The fuel elements and the structural member, if present, have circumferentially extending pads in the region where they engage one another. The invention is described with reference to a sodium-cooled fast reactor which comprises a double-walled tank having an interlayer of thermal insulation, which tank contains the core and the primary circuit, including a plurality of heat exchangers, in a reservoir of the primary coolant, i.e. sodium. The core comprises closely packed hexagonal fuel assemblies on a triangular lattice, a central zone of the assemblies containing fuel of a lower enrichment than that contained in the assemblies in the next zone, this difference of enrichment serving to provide a flatter power distribution. This latter zone is surrounded by an inner reflector zone comprising assemblies containing neutron reflecting material constituted principally by graphite, which in turn is surrounded by assemblies containing breeder fuel and an outer reflector zone.
