Title: Method of preparing beta'' alkaline alumina artifacts
IPC: H01M10/39
Filed: 1977-05-26
Abstract: This process consists, in succession, in carrying out an intimate mixing of alumina and alkali metal carbonate powders, in heating the said intimate mixture in an open crucible, in allowing this mixture to cool freely, in crushing the powder thus obtained, in carrying out the shaping of the components and in sintering the latter, in which process, after the shaping, an alkali metal compound is deposited on the surface of the components in contact with the atmosphere, the said sintering being carried out by heating the components at a temperature between 1500 DEG  and 1700 DEG C for 5 minutes to 4 hours, and in then allowing to cool to room temperature. The components thus manufactured can be used as solid electrolytes in sodium/sulphur generators.

A breaker-reinforced pneumatic tyre has one sidewall (preferably the outboard wall) more supple than the other to reduce lateral flexibility. Described methods of achieving this effect are (Figs. 1-7, not shown, respectively) (a) inserting more carcass reinforcement plies in the less supple wall; (b) using a harder and/or thicker layer of rubber in the less supple wall; (c) forming the carcass in the less supple sidewall of cross-laid cord plies and in the other sidewall of radial cord plies; (d) providing fillers of which the one in the less supple sidewall extends further up the wall and is optionally harder than the other filler; (e) reinforcing the less supple sidewall with a flipper extended into its radially inner region, the other bead having a conventional or no flipper; (f) forming the beads with different minimum diameters, and hence sidewalls of different radial heights; and (g) giving the less supple sidewall a radius of curvature (in radial section) greater than that of the other sidewall. Alternatively, the carcass plies in the less supple sidewall may be calendered in a harder mixture than these in the other sidewall. The rubber of sidewall (14) may be white.

Abstract: 941,377. Electric selective signalling systems. WESTINGHOUSE ELECTRIC CORPORATION. June 30,1960 [July 2, 1959], No. 22882/60. Heading G4H. In a system in which information is transmitted by means of a coded train of pulses, the duration of each pulse and of each space between adjacent pulses, being variable, the durations of the pulses and spaces in a received train are detected and registered in order and are used to provide a unique signal representing the information. In response to operation of a push button PB1-PB9 Fig. 1B, a start relay ST and a combination of relays M1, S1, M2, S2, M3 operate. The pulse train is generated by relays MLP, MSP, SLP, SSP and SL, SLX, Fig. 1A under control of relays M1-M3, S1, S2 as follows. First, either MLP or MSP operates depending on whether or not M1 is energized, a pulse is transmitted over line SC and SL operates to open contact SLa. MLP is slow to release whereas MSP has a short release time so that either a long or a short pulse is transmitted. At the end of the pulse, either SLP or SSP is operated by S1, SLX operates to open SLXa, and a long or short space is transmitted, SLP being slow-to-release and SSP having a short release time. The second pulse, second space and third pulse are generated similarly under control of M2, S2, M3, after which the transmitting circuit is reset. At the receiver, Figs. 2A- 2C (not shown) similar circuits are used to detect the durations of the pulses and spaces and to register each code element by energizing the appropriate ones of respective pairs of relays, the contacts of which are arranged so that the appropriate one of 32 indication relays is energized.
