Abstract: 805,324. Dispersing liquids by gaseous pressure. PYRENE CO. Ltd. Nov. 6, 1956 [Nov. 15, 1955], No. 32666/55. Class 102(2). [Also in Groups XXI and XXIX] The discharge hose 6 of a container 1 for storing fire extinguishing liquid under pressure extends upwards from a point more than half way down the container and at its lower end is carried by a slide valve member 7 which in its normal position seals the interior of the container from the bore of the hose and in a discharge position puts the two in communication one with another, the contents being discharged upon movement of the free end of the hose 6 to move the valve member 7 from the normal to the discharge position. In Fig. 1 the valve is a rotary slide valve in which a passage 8 in the member 7 can be brought into alignment with either one of two passages 4, Fig. 2, in a circular boss 3 let into the container wall, by swinging the hose 6 in either direction about the axis of the boss 3. The member 7 is pivoted on a spigot 5 and is pressed against the boss 3 by a spring ring 9. O-ring packings 15 in circular grooves around the passages 4 from a seal between the boss 3 and the member 7. When out of use, the nozzle of the hose 6 enters a rubber socket 42 near the top of the container 1. The spigot 5 houses a valve 44 through which the container may be put under pressure. In the embodiment of Fig. 6 the slide valve member 36 is arranged for limited rectilinear movement within a casing 33 secured to the container wall. When the member 36 is pulled outwardly by means of the hose 6 a passage 34 is opened to allow discharge of the container 1. To prevent unauthorized return of the member 36 to its closed position, a split spring ring 39 provided around a neck 40 of the member 36 is arranged to expand, when the member 36 is pulled out of the easing 33, to act as a stop between the casing 33 and a head 37 on the valve member 36. In another embodiment, Fig. 4 (not shown) the valve member is arranged for rectilinear sliding movement in a casing secured within the container. The slide valve member may be spring loaded into its normal position. The hose may terminate on a head for generating mechanical foam.

Title: Process for the production of steel from tin plate scrap
Inventor: WRIGHT PETER AMYAS
IPC: C22B25/06
Filed: 1962-08-31
Abstract: A process for the production of steel from tin plate scrap comprises adding to the molten scrap a metal oxide or sulphide, preferably iron oxide or sulphide, capable of reacting with the tin therein, and subjecting the melt to vacuum treatment whereby the tin is substantially wholly removed for recovery, while the residual metal is utilized for the production of steel. For the reaction FeS+Sn-->Fe+SnS, in one example scrap was melted under 1 mm.Hg. vacuum; the temperature was held at 1570 DEG  C. for 10 minutes; the calculated quantity of FeS was added and the pressure held at 2 mm. at the same temperature for 17 minutes; and the pressure was reduced to 1 micron and held for 15 minutes.  In a second example, scrap was melted; argon was admitted and FeS added, the pressure being then reduced to about 2 mm. and the temperature held at 1570 DEG  C. for 15 minutes; the pressure was reduced to about 1 micron for 15 minutes and then for a further 15 minutes.  Excess sulphur is preferably removed by reagents, Pb and Cu and other metals having slightly volatile sulphides will be removed or reduced at the expense of FeS if they occur in the scrap.  The tin may be recovered in the form of SnS or SnO from filters or fume catchers.ALSO:A process for the production of steel from tin plate scrap comprises adding to the molten scrap a metal oxide or sulphide, preferably iron oxide or sulphide, capable of reacting with the tin therein, and subjecting the melt to vacuum treatment whereby the tin is substantially wholly removed for recovery, while the residual metal is utilized for the production of steel.
