Title: Pouring of molten metals
IPC: B22D37/00
Filed: 1974-01-15
Abstract: 1490981 Metallurgical vessels FLOGATES Ltd 14 Jan 1975 [15 Jan 1974] 01913/74 Heading F4B A sliding plate for the sliding gate valve of a metallurgical vessel comprises a flat refractory member 12 having an opening 13, and a refractory insulating casting 14 bonded to the underside of the member 12 by a layer of cement and having a nose 20 formed with a tapered bore receiving a frusto-conical nozzle liner 22 which is cemented in place and which extends through opening 13 to terminate flush with upper sliding surface of the member 12. The assembly is reinforced by a metal tray 16 and a metal sleeve 17 which are welded or brazed together. The member 12 can be 85- 90% Al 2 O 3  and the casting 14, 40% or 60% aluminous fire clay or 70-90% alumina. The liner 22 is first made too long and after the cement has set the upper end is ground flush with the surface of plate 12. The liner may be made of a high density refractory having 86-90% alumina or zirconia. The cement bonding the liner in place is weak so that the liner can easily be forced out and replaced. As described in Specification 1,478,978 the liner can comprise a main tubular body and an inner member, extending at least half-way down the liner, the inner member being made of a material with a greater resistance to slag and metal erosion.

Title: Vehicle brake mechanism
IPC: B60T11/24
Filed: 1963-01-17
Abstract: 974,575. Hydraulic brakes. KELSEYHAYES CO. Jan. 17, 1963 [Jan. 17, 1962], No. 2089/63. Heading F2F. A brake system for a vehicle includes two parts 90, 94 inertia responsive to move relatively oppositely longitudinally of the vehicle, the system comprising a fluid pressure generating device 10, separate fluid pressure lines from the device extending to different sets of wheel cylinders 54, 79 respectively and a valve mechanism 58 connected in one of the fluid lines. The valve mechanism has relatively movable portions connected to the inertia responsive parts and includes a normally open valve member which is closed by relative movement of the portions at a predetermined deceleration. In the construction shown the fluid pressure device consists of a master cylinder having a stepped bore in which work a mechanically actuated piston 13 and a floating piston 28. The floating piston is sealed with respect to the bore at both ends of a reduced central portion which forms a small annular chamber 31, the chamber straddling the step in the bore. The chambers 18, 35 formed between the pistons and the bore communicate with separate compartments of a reservoir 20. A spring-loaded valve member 42 is mounted in a cage member 37a in chamber 35, the valve member being held open by a spring-loaded plate 37 in engagement with the piston 28. The valve mechanism 38 comprises a residual pressure valve 65 and a ball valve spring biased towards its seat 69 and held therefrom by a spring-loaded rod 83 engaging the vehicle part 94 through an adjusting screw 104. The two inertia responsive parts 90, 94 which consists in the tongue tube and a bracket of the transmission casing 91 are connected by a resilient body 95. On actuation of the piston 13 and thus of the piston 28 fluid passes from chamber 18, 31, through valve 58 to the rear wheel cylinders 79, valve 42 closing the passage between chamber 35 and reservoir 20 allowing fluid to pass through a residual pressure valve (not shown) to the front wheel cylinders 54. On the predetermined vehicle deceleration being reached, ball valve 82 is closed to cut off the fluid supply from chamber 18 to the rear wheel cylinders, the pressure build-up in these cylinders being greatly reduced as the build-up is governed by the small chamber 31. In a second embodiment a conventional master cylinder having a divided fluid line is employed, a valve being connected in the line to the rear wheel cylinders (Fig. 2, not shown). The valve is connected between the transmission casing and the vehicle frame in a similar manner to the first embodiment to bias a ball valve from its seat. A resilient block is arranged in the ball valve chamber, the block being provided at its face furthest from the valve with a fluid circuit connected to the rear wheel cylinders. On the closing of the ball valve, pressure increases from the master cylinder reacts against the block to effect pressure increases in the rear wheel cylinder circuit less than those of the master cylinder.

Title: A process for the removal of multivalent metal ions from aqueous solutions
IPC: B01J49/53
Filed: 1966-01-20
Abstract: In a process for the replacement of multivalent ions in aqueous solutions by alkali-metal ions by ion-exchange, the ion-exchanger is regenerated by a concentrated solution of an alkali-metal salt and the effluent from the regeneration stage is treated with a precipitant for the multivalent ions containing alkali-metal ions, the precipitate is separated and the remaining solution of the alkali-metal salt is again employed for further regeneration of the ion-exchanger. The regenerant solution is usually a chloride while the precipitant is usually a silicate, phosphate or carbonate.  The recycled regenerant is diluted during the process and make up salts are added.  The process above may be applied to the removal of e.g. Zn++, Cu++Mn+++, Fe+++Cd++ and Al+++.  Copper is precipitated as basic copper carbonate by alkali metal carbonate. Solutions of iron are oxidized before precipitation may be carried out in more than one stage, e.g. to separate the trivalent ions before the bivalent ones, or to separate calcium from magnesium.
