    Abstract: In the continuous production of W or Mo from its oxide by electrolysis in a fused bath of at least one alkaline earth metal halide and a mixture of the oxides of at least one alkaline earth metal and of the product metal to cathodically deposit pure ductile and crystalline metal, the product metal oxide is replenished by addition as it is consumed and accumulation of surplus alkaline earth metal oxide is prevented by passing chlorine gas through the melt to convert the surplus oxide to the chloride. Typically the alkaline earth metal compounds used are those of Ca and preferably the baths contain 0.1 to 15% free CaO. In place of the mixture of alkaline earth and product metal oxides, there may be used the ores scheelite and powellite for W and Mo respectively, while for Mo production, the crude Ca Mo O4 obtained commercially by roasting MoS2 may be used. The temperature of the bath is 1000 DEG C. the applied voltage is 2.2 to 2.4 V, the cathode current density is 3.5 to 4.1 amps/in2, and chlorine is blown through the bath via a tube of quartz or silimanite (aluminium silicate). The cathode deposit is agitated in water to dissolve out adhering salt and washed in hydrochloric acid.

    Abstract: 732,674. Razors. BANK OF AMERICA NATIONAL TRUST & SAVINGS ASSOCIATION. April 4, 1952, No. 8657/52. Addition to 697,314. Class 30. A modification of the removable magazine disclosed in the parent Specification for mounting a ribbon blade in a razor comprises two separate shells one containing a feed spool and the other a winding spool, each shell being connected to one end of a spacer element overlying the operative portion of the blade. As shown the magazine comprises a supply shell 24 and a take-up shell 25 held in spaced relation by the curved ends 40 of a spacer element 26 beneath which a ribbon blade 27 extends. The magazine is received as a unit in the razor head 11 a resilient latch 20 and a bridge member 15 being rotated about their pivotal connections 21 and 16 for receipt of the magazine. In the position of use the blade 27 and the overlying straight portion 30 of the spacer element are clamped between the bridge 15 and a lip 14 of the head 11. In a modification the spacer element is integral with the shells.

    Abstract: atm incluindo recursos de privacidade aprimorados. um método para minimizar claridade e/ou aumentar privacidade para um usuário de um dispositivo autosserviço é fornecido. o método poder incluir dispositivos mecânicos tais como um visor e/ou cobertura fixos ou uma tela de sobreposição de redução de claridade articulada operada por usuário. o método pode incluir adicionalmente usar sensores que detectam os olhos do usuário e outros ensores para detectar uma fonte de luz que produza claridade. informação destes sensores pode ser enviada para um sitema controlado por computador que opera um sitema de acionadores. os acionadores são operados pelo computador em resposta ás entradas de sensor para ajustar o ângulo de tela em relação ao usuário e/ou aumentar privacidade contra olhos ou câmeras observando clandestinamente.
