Patent GB-353749-A (GB)
Title: Process for the simultaneous production of phosphorus, or phosphoric acid, and alumina
IPC: C01F7/02
Filed: 1930-09-04
Abstract: Aluminium phosphate is introduced, together with reducing agents such as coke, into an electrically heated phosphorus furnace, and fused at temperatures of about 1600-1700 DEG  C., sulphides, especially sulphide ores, being mixed with the charge in such quantities that the alumina liberated from the aluminium phosphate dissolves in the aluminium sulphide formed by reaction with the sulphides.  The aluminium oxide-sulphide melt is tapped off and worked up into alumina.  Phosphorus may be recovered in known manner by the condensation from the effluent furnace gases, and phosphoric acid may also be produced directly in known manner. A metallic alloy containing the gangue elements of the phosphate may also be tapped off from the furnace.  In the examples, aluminium phosphate, preferably after dehydration, is fused with the addition of coke and iron sulphide.  The coke is taken in such quantity that it suffices to expel the phosphorus and also to reduce the iron of the sulphide, the ash constituents of the coke, and the gangue accompanying the aluminium phosphate.  Phosphorus and carbon monoxide escape during the fusion process, and the phosphorus may be converted into phosphoric acid in any known manner.  When the furnace is tapped, an iron alloy containing titanium, silicon and phosphorus, and an aluminium oxide-sulphide melt are obtained.

Patent GB-267630-A (GB)
Abstract: 267,630. White, A. E., (Remington Arms Co., Inc.). Dec. 22, 1925. Transfer-mechanism particularly applicable to the totalizers of cash registers such as that described in Specification 135,465 as open to inspection under Sect. 91 of the Acts, comprises a pawl capable of both rectilinear and rotary movements for effecting transfer, these movements taking place while the totalizer is disengaged from its actuators. Secured to each numeral wheel is a one-toothed disc 46 and a receiving pinion 45 and co-operating with the disc is a trip pawl 51 pivoted on a rod 47 and provided with a lug 55 engaging below a shoulder on a transfer pawl 56. A pin 58 on the latter normally engages a notch 53 in the trip pawl but at transfer the passage of the transfer tooth rocks the trip pawl to disengage the pin and force the transfer pawl forward on the rod 47, the trip pawl when released then returning to normal position under the action of spring 59 but with the pin 58 received in a notch 54. The continued rotation of the main shaft 35 now causes, through a pair of cams 70, 71, a clockwise displacement of a lever 66 so as through a pin 65 engaging a notch 64 to rock the transfer pawl into engagement with the next higher pinion 45 and to draw it rearwardly on the rod 47 to effect the transfer. The pin 58 has now returned to notch 53 and on the counterclockwise movement of lever 66 the transfer pawl rotates about the rod to its normal position. To prevent overthrow, a second tooth 75 is provided on the transfer pawl to engage the pinion and stop any extra movement thereof. Spring-controlled detents 80 for the totalizer pinions are also provided. To prevent interference with the engagement and disengagement of the totalizers with the actuators 301 due to the disposition of the transfer pawls and their operating pins 65, the cams 70, 71 are so formed as to impart to the pins a preliminary displacement to allow the free movement of the totalizers both into and out of mesh. Specifications 157,824 and 157,825 are referred to.
