Patent GB-324103-A (GB)
Title: Improvement in apparatus for conveying solid materials through pipes by means of compressed air
IPC: B65G53/46
Filed: 1928-10-18
Abstract: 324,103. Miller, T. F. Oct. 18, 1928. Pneumatic conveyers.-Material is admitted to a pneumatic conveyer through a series of chambers A, B, C provided with valves D, E and a series of chambers L, N containing means for aerating it. A pipe p containing a valve F connects the chambers B, C and communicates with the atmosphere through a pipe I. The valves D, E, F are actuated by rotary cams V1, V2, V3 through connecting rods W1, W2, W3 &c. When the valve D opens, material falls into the chamber B which is then in communication with the atmosphere. After the closure of the valve D, the valve F moves to close the pipe p and put the chambers B, C in communication. After this operation the valve E opens and the material passes into the chamber C. The valve E then closes, and the valve F moves to put the chamber B in communication with the atmosphere. The -surface of the valve D is kept free of material on returning to its. seating by a ring H which descends with the valve until it is caught by the projections J. A screw K transfers the material from the chamber C to a chamber L in which it is mixed by paddles P with compressed air admitted by the pipe A. On leaving the chamber L the material passes through the chamber M to a chamber N through which it is propelled by paddles 0 and delivered to a chamber R. Compressed air admitted to the chamber R through a ring of apertures U drives the material through the pipe line Z. In a modification, Fig. 4, the screw K and paddles P are dispensed with, and the flow of material is regulated by adjustable hinged dampers K<1>.

Patent GB-377519-A (GB)
Title: Processes of making iron-chromium nickel alloys
IPC: C21C7/00
Filed: 1931-11-02
Abstract: A process of making alloys containing iron, chromium and nickel consists in reacting on nickel matter with ferrochromium containing carbon.  The alloy may be further refined to remove excess carbon by oxidation, for example, by means of a slag or by Bessemerizing with oxygen or air enriched with oxygen &c.  For making alloys of the stainless type the iron nickel chromium alloy may be diluted with iron before or after refining.  Additions of other elements may be made to the steels for improving the properties.  In examples the mixture of matte and ferrochrome with lime and fluorspar is charged on to a molten bath of lime and silica in an open arc furnace, to produce the ferrochrome nickel alloy.  The alloy is treated directly in a converter or is diluted with steel scrap, tapped into a converter and blown, ferromanganese and ferrosilicon being added to the ladles before casting the ingots.
