Title: Process for making electrical connections to a microcircuit chip
Inventor: HAGON PETER JOSEPH
IPC: H01L21/60
Filed: 1968-05-06
Abstract: 1,225,042. Soldering. NORTH AMERICAN ROCKWELL CORP. 6 May, 1968 [4 May, 1967], No. 21405/68. Heading B3R. [Also in Division H1] The Figure shows part of an interconnection substrate for several micro-circuit chips. The substrate is provided with any necessary crossover connections (Fig. 3, schematic, not shown). Conductors 12 on the substrate are provided with raised bonding portions 20 which match with corresponding raised regions on the microcircuit chip to be attached. Bonding is effected by heating to form a eutectic from materials in the raised portions and regions. As shown, the raised portions 20 are low resistivity semiconductor 22 (germanium or silicon) bearing a coating 24 of a eutectic-forming metal. The raised regions on the chip (not shown) are similar-the metal may be the same or different. When the assembly is heated a eutectic is formed from the semi-conductor (of both the portions and the regions) and the or both metals. Useful metals to form a eutectic with silicon are gold, aluminium, silver, platinum, antimony, magnesium, copper, lead, and nickel. The atmosphere used may be, for example, air, when gold is used or argon, nitrogen, hydrogen, or forming gas when aluminium is used. The process may be modified by providing all the semiconductor to form the eutectic on either the chip or substrate and all the metal on the other. The substrate may be entirely of insulating material or may be of insulator-coated metal. The ridge 30 (having parts similar to those of the portions 20) matches a ridge on the chip, the two being bonded together to hermetically seal the face of the chip and the devices it contains. The ridge is separated from the conductors 12 by insulation 36. Several types of conductors which may be used are illustrated. Conductor 12b is metallic; conductors 12c each have a core 27 of relatively oxidizable metal protected by a tarnish-resistant metal layer 28; and conductor 12a are of low resistivity semi-conductor coated with a metallic layer 26 to decrease the overall resistance.

Title: Improvements in and relating to a fuel assembly for a nuclear reactor and a nuclear reactor core comprising such fuel assemblies
Inventor: MARSTRAND JORGEN
IPC: G21C3/344
Filed: 1971-04-19
Abstract: 1,274,188. Fuel elements. ATOMENERGIKOMMISSIONEN. 19 April, 1971 [13 Feb., 1970], No. 21626/71. Heading G6C. A nuclear fuel assembly comprises a plurality of parallel fuel rods arranged in a lattice in which the points of intersection of the axes of the fuel rods with a plane perpendicular to the axes form a regular pattern of points constituting vertices in a plane configuration of regular geometrical figures, a plurality of deflectors parallel with the fuel rods arranged in the common vertices of adjacent geometrical figures, and a plurality of grids distributed in the axial direction of the assembly, which grids permit the fuel rods to expand axially but support them transversely. In one embodiment, shown in Fig. 1, the fuel rods are arranged in groups of six, such as the fuel rods 1-6, each group surrounding a deflector 7. The marginal groups comprise less than six fuel rods. The deflector 7 is of cruciform cross-section and comprises four helical blades which impart a vortical motion around the axis of the passage formed by the surrounding fuel rods to coolant water flowing through the passage. By means of this vortical motion, a separation of steam and water takes place, the steam moving towards the centre of the passage and the water towards the surrounding fuel rods on which it forms a film and ensures good heat transmission. The fuel rods pass through supporting grids 8, the deflectors being rigidly connected to these grids as by welding. The parts of the grids 8 through which the deflectors 7 pass are formed as rings which facilitates the mounting of the deflectors since they can assume any angular position in the rings before being welded. The pitch of the helical blades of the deflectors 7 may vary along the deflectors in order to make allowance for the varying steam content of the coolant. In an alternative embodiment (Fig. 3, not shown), the fuel rods are in groups of eight and mounted in a quadratic pattern.

Abstract: 1,255,019. Chimney linings. SERVOTOMIC Ltd. 16 Feb., 1970 [15 Nov., 1968; 29 April, 1969], No. 54256/68 and 21678/69. Heading F4J.  A method of lining a flue comprises threading through the flue a flexible but self-supporting tube of less cross-sectional area, filling the space between the flue and tube with cementitious material and allowing the latter to set. Thereafter the tube may be burnt away by use of the appliance to which the flue is attached. By self-supporting is meant a material that will withstand the pressure of the cementitious material without internal fluid pressure and will retain the desired shape. The self-supporting tube may be made of corrugated paper treated to render it impervious or resistant to water and/or to improve its combustion. The flue may be initially lined with a deformable material e.g. polyvinyl chloride to prevent seepage of corrosive liquid condensates.

Title: Improvements in and relating to combined friction and positive clutches
IPC: F16D23/02
Filed: 1945-08-24
Abstract: 603,591. Clutches. BENDIX HELICOPTER, Inc. Aug. 24, 1945, No. 21739. Convention date, May 29, 1944. [Class 80 (ii)] [Also in Group XXXIII] A friction clutch and a positive clutch are arranged in parallel and means are provided to disengage both clutches simultaneously and to retain the positive clutch out of engagement by intermittent power impulses until the friction clutch has been re-engaged. In a helicopter rotor drive, a driving shaft 26 has a sleeve 27 keyed thereto and carrying a rotatably mounted sleeve 31 formed at one end with a bevel gear 32 which meshes with bevels 19, 20 connected to two driven shafts 17, 18. At the other end of the sleeve 31 are journalled rollers 44 of a one-way clutch, the outer race 42 of which carries journals for planet pinions 43 meshing with an annulus 24 fixed to the casing 22, 23. The sunwheel 62 of the epicyclic reduction gear 24, 43, 62 is formed integral with the boss of a friction clutch outer member 59 free to rotate on the sleeve 27. The inner member 49 of this friction clutch is in splined connection with the sleeve 27 and is normally urged to hold the friction plates 56, 57 in engagement by a spring 47. The clutch inner member 59 has an annular extension 63 in which are formed a number of equi-distantly spaced grooves 64 open at their right-hand end. The outer member 59 has a portion 65 which normally lies within extension 63 as shown, and carries a number of spring-loaded plungers 70 which engage with the grooves 64 to provide a positive drive. Each plunger has a flange 74 normally urged against a shoulder 75 which has a counterbore 67 above it and in communication with the bore of the shaft 26 by the drillings 77, 78, 79. With the components in the position shown, there is positive drive from the shaft 26 through the sleeve 27, centre 49, plungers 69, sun-gear 62, planet carrier 42, one-way clutch 44 and bevel gear 32 to the driven shafts 17, 18. If the clutch 50 is disengaged by the shifter 54, the centre 49 moves to the left and the plungers 69 disengage, thus allowing relative motion between the member 59 and the sleeve 27 so that pressure fluid from the bore of the shaft 27 can be passed through the drillings 77, 78, 79 to the counterbore 67 and thus cause the plungers 69 to be depressed. On re-engagement of the clutch 50, the plungers 69 will be held depressed by the intermittent flow of fluid, until the speed of the member 59 is sufficient to prevent pressure fluid flowing in the drillings 77, 78, 79 whereupon the plungers will move outwards and provide a positive drive again. Specification 590,514, [Group XXXIII], is referred to.
