Abstract: 1514640 Molten-salt reactors ELECTRICITE DE FRANCE (SERVICE NATIONAL) and PECHINEY UGINE KUHLMANN 2 June 1976 [9 June 1975] 22789/76 Headings G6C In order to protect the primary vessel 3 of nuclear reactor of the molten fuel-salt type in which the internal space of the vessel apart from that occupied by the reactor components is filled with a carbonaceous packing material, the free space 13 created between the carbonaceous material 7 and the steel of the vessel 3 when the primary vessel is heated to a predetermined temperature such as 400C is filled with an auxiliary salt which does not contain any fissile or fertile material and which has a melting point below the temperature to which the vessel has been heated. For example, the auxiliary salt may consist of the eutectic mixture of lithium and beryllium fluorides which is chemically compatable with the fuel salt proper and is inert from a nuclear point of view. The auxiliary salt not only fills the space 13 but also the intensities 14 formed within the material 7. The temperature of the primary vessel is then reduced below the melting point of the auxiliary salt which then crystallises in the space 13 and interstices 14 whereafter the reactor is charged with the final fuel salt and the vessel is maintained at a temperature below that of the melting point of the auxiliary salt. The vessel is thereby protected by the carbonaceous material and the lining of the auxiliary crystalline salt from the molten fuel salt within the reactor.

In fabrication, plural unperforated green ceramic laminµ 11 (Fig. 2) are stacked with the binder rich sides facing upwards; each lamina comprising a PETP carrier with an alumina layer therein. The uppermost lamina 11a forms the base of a blind hole structure in the package and its upper face is metallized at 11b according to a predetermined circuit pattern by silk screening with a paste of metal, glass frit, binder, and solvent. Plural laminµ 12 are perforated according to a required blind hole pattern and superimposed on unperforated stack 11 with binder rich sides uppermost; the upper lamina 12a having its PETP carrier intact to function as a mask.  Alternatively the package may be fabricated of precast ceramic layers. The complete assembled package 10 is then attached centrally of a rotatable, wheel or plural packages may be disposed symmetrically of the centre of such wheel (Figs. 3, 4, not shown), and the blind holes are filled by brushing or spraying with a metallic paste of Mo powder with butyl acetate, ethyl cellulose, and a hydrophilic agent. Rotation of the wheel centrifugally removes excess paste and coats the walls of the blind holes with an inner lining of the paste. The masking layer is then removed from the upper lamina 12a and the package is, e.g. silk screen metallized to form required circuit patterns; after which it is dried and sintered into a consolidated mass. Through holes may be provided by drilling all the laminµ according to a predetermined pattern and lining with metallic paste as above (Fig. 6, not shown). Holes of an already fired package may be metallized over a mask with metallic paste comprising, e.g. Ag-Pd; Ag-Au-Pd; Au; Cu; spinning to remove excess, removing the mask, and re-firing. Two packages 10 may be interconnected by pins 17 carried by metallized blind holes 15 and connected at upper ends to surface pads 18; while Si wafer 19 carried by the upper package is connected to the circuitry thereof by beam lead 20 (Fig. 5).

Title: Improvements in or relating to brakes
IPC: F16D65/22
Filed: 1934-08-17
Abstract: 435,221. Brakes. BUDD WHEEL CO., 2500, Hunting Park Avenue, Philadelphia, U.S.A.-(Assignees of Eksergian, C. L.) Aug. 17, 1934, No. 23742. Convention date, June 30. [Class 103 (i)] A brake comprising a pair of shoes each of which anchors at one end or the other according to the direction of drum rotation, load applying means between each adjacent pair of shoe ends to which force is transmitted through operating levers, the fulcrum of one of which is further from the drum axis than that of the other with a given direction of drum rotation is characterized by the fact that the effective lengths of and/or the forces applied to the levers are predetermined to cause the application of equal loads to the shoes. Brake shoes 15, 151 have recessed ends 32 normally engaging anchor pins 20 on the anchor plate 10. Cam levers 19 provided with projections 22 disposed between the shoe ends are formed each with a slot through which the pin 20 passes so that the levers float about the axis of the brake. A yoke 24 is connected by links 27 to the levers, the links having holes for engaging notches 28 in the levers. Springs 53 keep the links in contact with the levers and yoke. The yoke is actuated by a shaft 43 passing obliquely through the anchor plate 10 and having an arm 45 with ball-andsocket engagement 46 with the yoke and an external operating arm 47. For a steering- wheel brake, the yoke is actuated by a thrust rod passing through the steering pivot. When the yoke is moved downwardly to apply the brake with the drum rotating in the normal direction indicated by the arrow, the left-hand end 17 of shoe 15 and the right-hand end 17<1> of shoe 15<1> remain in contact with the corresponding pin 20. Since the inner projection 22 of the left-hand lever 19 and the outer projection of the right-hand lever become the fulcra for applying the load to the upper and lower shoes respectively, these loads would be unequal if equal pressures were applied to levers of equal length. To equalize the load applied to the two shoes and thus their braking action, the right-hand link 27 is attached a short distance from the end of the lever as shown and the arms 25, 26 of the yoke are also of unequal length. The anchor pins may be radially adjustable. A modification is shown in which the levers 19 extend from the projections 22 radially away from the centre of the drum. Compensating for wear.-Adjusting means for the shoes comprise a, shank 32<1> slidable non- rotatably in a socket formed by a slot 34 in the web of the shoe and plates 35 welded on each side of the web. An adjusting nut 36 turns on the shank and is locked by engagement of the edges of the plates with recesses in the nut.
