Title: Improvements in and relating to furnace door frames
IPC: F23M7/00
Filed: 1954-08-10
Abstract: 774,209. Furnace door frames. STEINMULLER GES., L & C. Aug. 10, 1954 [Dec. 8, 1953; March 27, 1954; May 22, 1954], No. 23193/54. Class 51 (2). In a water-cooled door frame for a Siemens- Martin furnace of the type in which the cooling system forms part of a boiler circulation system, the door jambs 1a, 1b (Fig. 1), and the lintel 1c comprise separate chambers of square or rectangular cross-section with their own supply pipes 2a, 2b and 2c, and return pipes 3a, 3b and 3c, each chamber being divided by longitudinal partitions 4 (Fig. 2) defining narrow cooling spaces in each longitudinal face of the chamber. Each supply pipe 2 (Fig. 2) extends through a plate 5 at the bottom of the chamber and ports 6 allow passage of the water to the narrow cooling spaces. The number of ports 6 is varied according to temperature conditions at the particular face concerned. Instead of being separated, the chambers 1a, 1b and 1c may be combined as indicated at the left-hand side of Fig. 1. Some of the inlet pipes 2a &c. and outlet pipes 3a &c. may be made in square section and welded to the lintel to support a girder holding the skewbacks of the furnace roof, Fig. 4 (not shown). A modification, Fig. 6, has partitions 4 and end-plates 40-14 arranged to define two parallel paths for the water, which passes in each case through two flow passages in succession. Thus water sup. plied to a compartment 16 by pipe 2 from a header 15, flows in turn through passages 17 and 19, and out through pipe 3, the other two flow passages being supplied through pipe 21 and having a return pipe 3<SP>1</SP>. The intakes for pipes 2, 21 inside the header 15 are formed with strainers, Fig. 8 (not shown). In a further modification, Fig. 10, the supply pipe 2a in the jamb 1a terminates above the plate 5 into which is screwed a pipe 28 formed at the top with a strainer 28<SP>1</SP>. A removable cover 29 is provided at the bottom of the jamb. The lintel 1c has a bottom plate 4<SP>1</SP> formed with internal ribs 27 to intercept sludge separating out of the water. The flow passages can be divided into parallel sections by baffles, Figs. 11 and 12 (not shown). In a final modification, Figs. 14 and 15 (not shown), the hollow space defined by the walls 4 is offset along one side, and the inner wall limiting this offset portion is recessed to receive sludge strainers forming the ends of the supply pipes, the flow passages being divided by transverse ribs.

Title: Improvements in continuously variable speed-ratio transmission mechanism
IPC: F16H61/662
Filed: 1946-08-06
Abstract: 615,380. Continuously-variable-speed gear. TILTMAN, A. H., LANGLEY, M.. and GERRITSEN, J. J. Aug. 6, 1946, No. 23294. [Class 80 (ii)] A continuously-variable-speed gear comprises two conical members, male and female, both facing the same way and mutually displaceable axially to produce a change in ratio, the conical members being in rolling contact with a ball rotatable about an axis substantially radial to the cones and which ball may be either the driving, driven or idling element. In one embodiment, the ball 9 is splined to the driving shaft 3 and is in contact with the driving and idling cones 10, 11 respectively. The cone 10 is rigid with the hollow shaft 12 to which is attached a further driving cone 13 surrounded by an idler cone 14 and in contact with the ball 15 splined to the driving shaft 17. The balls 9, 15 are loaded into contact with the cones by a spring 34 acting through a thrust bearing 26, and are held apart by discs 23, 24 and balls 25 which are free to rotate and move axially about the shaft 12. The driving and driven shafts 3, 17 are journalled in housings 5, 19 which are rigid with and axially free respectively in the casing 6. Adjustment of the inner cones 10, 13 axially relative to the idler cones 11, 14 produces a relative change in ratio between the input and output shafts and may be made automatic with input speed by the utilization of centrifugal pressure of oil which enters the chamber 37 through the ducts 41, 44. This pressure is balanced by a variable ratio spring 38 so that the speed of the output shaft remains substantially constant and independent of the input shaft speed. In modifications, two sets of idler balls of different diameters are employed between four pairs of cones, and use is made of centrifugal forces on different size balls to obtain a constant output shaft speed.

Patent GB-403768-A (GB)
Title: Method of manufacturing low-carbon chromium alloys
IPC: C21C7/00
Filed: 1932-08-26
Abstract: In a method of making low carbon chromium alloys, such as ferrochrome and chromium steel, in the electric furnace, in which the chromium is added at least in part as a high carbon alloy, and decarburization is effected by a slag containing chromium oxide, the high carbon chromium alloy is added to the slag in the form of small pieces or powder continuously over a long time or in portions with short intervals.  Ferrochrome containing for example 6-10 per cent of carbon, preferably entirely pulverized is refined by a slag containing chromium oxide and ingredients such as lime.  To make chromium steel, high carbon ferrochrome and iron, for example sponge iron, forge iron, or pig iron, are added to the slag.  Reduction in the chromium content of the slag is compensated by additions of chromium oxide, or iron oxide, etc., by blowing air or oxygen into the metal, or by an ample supply of air to the surface of the slag. Undesirable increase in the chromium oxide content is adjusted by adding reducing agents such as carbon, aluminium silicon-iron, silicon-chromium, etc.  The partial pressure of carbon-monoxide is kept low above at least a part of the slag by admitting a natural draught.  When drawing off the metal, the slag is left behind for a fresh charge.  Special alloying substances such as nickel, manganese etc. may be added to the metal in the refining furnace, ladle, or tapping furnace. Specification 196,260, [Class 82 (i), Metals, Extracting &c.], is referred to.
