Transfer mechanism of the externally-operated type for the totalizing-counters of calculating machines, &c., comprises a transfer actuating number constituted by a pivoted lever and a bell crank lever mounted on the free end of the lever and adapted to be moved to an operative posisition by the transfer tooth so as to advance the next higher numeral wheel one step during the subsequent movement of the main operating shaft. In the form shown in Figs. 1 and 2 the numeral wheels 1 are provided with ten teeth 3 and with single transfer teeth 4 each of which is adapted to co-operate with the segmental end 8<1> of a corresponding bell crank lever 8 pivoted at 7 to a lever 5 and provided with an arm 9 having a nose 10 adapted to engage the teeth 3 of the next higher wheel. The bell crank lever is maintained in one or other of its set positions by means of a spring blade 11 secured thereto and adapted to snap into one of two recesses 12, 13 in the lever 5. The lever 5 is pivoted to a shaft 5<1> and is limited as to its rotation by a bar 15 and the projections 14, 16. When the transfer tooth 4 rocks the lever 8 to the dotted position shown in Fig. 1 the subsequent movement of the shaft 19 causes the corresponding cam 18, the series of which are arranged in staggered relation on the shaft, to engage the projection 17 of the lever 5 and raise it so as to advance the higher wheel. The projection 20 on the cam then en. gages the end 21 of the segmental portion of the bell crank lever and restores it to normal position. The lever 5 returns to its initial position by gravity or is compelled to do so by reason of the tooth 4 being caused to engage a projection 6 on the lever 5 before it meets the bellcrank lever. In a modified construction the pivoted lever 5 is formed as a bellcrank lever and is provided with projections engaging cam discs mounted on the shaft 19 to ensure positive action.

Abstract: 1,137,738. Refractories. WILD BARFIELD Ltd. 9 May, 1967 [13 May, 1966], No. 21328/66. Heading C1J. Refractory shapes are produced by kilning shapes derived from slurries containing aluminium hydroxychloride (AHY) and a grog and which is rendered alkaline by an alkali or alkaline earth metal oxide or hydroxide, an alkaline reacting salt of an alkali or alkaline earth metal, or an alkaline gas such as ammonia. Suitable grogs are molochite, sillimanite, high alumina and fused recrystallized reground alumina materials. The slurries are best prepared by mixing the dry grog and alkaline material, such as magnesium oxide or chloride, with an aqueous solution of AHY. The slurry is cast into a mould (the addition of magnesium silicate or of aluminium silicate to the slurry improves the mould stripping process) where it gels and hardens. The hardened shape is removed from the mould, air dried, and kilned at 1250-1400‹ C.
