Title: Corrosion and heat resistant machine part, particularly blade for gas turbines, and method of its manufacture
IPC: F01D5/28
Filed: 1948-04-22
Abstract: Blades, nozzles, or exhaust tubes for gas turbines, or valve heads or seats for internal combustion engines, or other machine parts capable of resisting heat and corrosion at temperatures above 700 DEG C., are made from sintered and compacted powder of one or more of the metals tantulum, columbium, zirconium, titanium, tungsten and molybdenum and then provided with a coating of one or more of the elements boron, titanium, silicon or zirconium, which form a heat-resistant oxide coating at the operation temperature, or of an oxide of any of these elements.  The coating may be applied by melting and infiltrating it into the surface layers of the body, by spraying it on, preferably in vacuo or in an inert atmosphere, or by depositing it by heating volatile compounds of the metal in vacuo; the body may be pre-heated during these operations.  The coating may also be deposited by heating the body in a pack comprising a mixture of the powdered coating, or suitable compound or salt of the coating, and an inactive material such as alumina or alundum or by dipping the body in a liquid salt mixture.  Subsequently, the diffusion of the coating into the surface layers may be improved by heat treatment in a furnace, by "brushing" with an oxyacetylene torch or by high-frequency induction heating.  The Specification as open to inspection under Sect. 91, describes also bodies made of osmium or iridium and coating of chromium or a metal of the platinum group, which do not oxidize at the operation temperature.  This subject-matter does not appear in the Specification as accepted.

Title: Improved metallurgical processes
IPC: C22B25/02
Filed: 1925-04-29
Abstract: Tin, molybdenum, and bismuth are recovered from their ores &c by treating them at an elevated temperature with gas containing sulphur. For example, sulphur vapour, hydrogen sulphide, or carbon bisulphide is passed over tin ore at 800 DEG  to 900 DEG  C.  The gas is diluted with water vapour, nitrogen, carbon dioxide, carbon monoxide, or a mixture obtained by the partial combustion of oil or coke to prevent the reduction of iron compounds and to sweep the tin sulphide through the apparatus.  Tin may be obtained from the sulphide by electrolysis, by heat, or by reduction with hydrogen, carbon monoxide, or similar gas.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the recovery of other volatile metallic sulphides. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to thermionic valve circuits
IPC: H04B1/16
Filed: 1927-04-27
Abstract: 290,032. Johnston, J. F. April 27, 1927. Thermionic amplifiers and detectors.-A series of valves, connected in cascade for amplification and detection in wireless receivers or for other purposes, are coupled to each other by direct plate-to-grid connections, and their filament currents and plate and grid voltages are supplied from a common source by connecting their plate. and grid circuits to tappings on resistances connected in series between their respective filaments. In the wireless receiving-circuit shown in Fig. 2, comprising a dectector valve V1 and two low-frequency amplifiers V2, V3 four resistances R1 - - R4 are connected in series with the valve filaments across a direct-current source. The input of the first valve is from a tuned aerial and grid bias is supplied by tapping on the resistance R1. Each valve has its plate directly connected to the grid of the following valve. A choke L2 is connected between the plate V1 and a tapping on the resistance R2 ; and a coupling-resistance R5 between the plate of the valve V2 and a tapping on the resistance R4 beyond the filament of the next valve V3 ; whilst the plate circuit of the last valve V3 is supplied from the positive side of the voltage source and includes the phones or speaker T. When high-frequency amplifiers are employed, a choke, resistance, or tuned circuit may be connected in its plate circuit. Filament current for individual valves may be adjusted by shunt rheostats. The improved form of coupling may be used in combination with transformer couplings at some of the stages; and when a large number of valves are connected in cascade, they may be divided into groups, and each group supplied and coupled in the manner of Fig. 2. When double-grid valves are used, the second grid may be given a positive potential by connection to. a suitable point on the resistances; and several sets of electrodes, forming a multiple valve, may be enclosed in the same envelope. Smoothing arrangements may be interposed between the valve circuits and the source of current, which may be either direct-current mains or a rectifier fed from A.C. mains. Bye-pass condensers may be connected across the tapping-points of the resistances R1 - -R4.

Title: Improvements in and relating to the production of cast iron
IPC: C22C37/04
Filed: 1948-04-26
Abstract: A process for the production of iron containing calcium comprises treating molten iron at a temperature of not less than 1650 DEG C with calcium carbide or calcium oxide or with a substance which at that temperature is converted into calcium oxide or calcium carbide, the melt being maintained at 1650 DEG C or higher until at least a part of the calcium carbide added or formed during the operation is dissolved in the iron.  Alternatively the addition may be made at the usual melting temperature of the iron, e.g. 1300-1500 DEG C, the temperature being then raised to at least 1650 DEG C.  An inoculant may be added after the addition of calcium and before casting.

In the present construction, the sighting-arm 11, Fig. 3, carrying sights 52, 53, is mounted on the axis 12 and is given a uniform but adjustable horizontal speed by means of a pin which slides in the slot 11<a> and forms the spindle of a roller 10 having a block sliding in the horizontal slot 49. The roller 10 is given a uniform movement in one direction by a snail cam 9 which is driven by a motor 1, through disk-and-roller mechanism 2, 3, 4 and bevel-gear 5, 7, a quick return being effected by the spring 51. The speed of the cam is varied by adjustment of the roller 3 by means of a rack and pinion 21, 22, spur gears 23, and knob 24 actuating an indicator 26. The vertical distance between the sight pivot 12 and the slot 49 is adjusted according to the height of flight by mounting the pivot on a block 13 forming a nut on a screw 15. The turning knob 16 is connected by bevel gear to a graduated ring 18 beside a pointer. The apparatus can be rotated as a whole about a vertical pivot 28, by means of the gearing 30, 31, and knob 32 fitted with a drift indicator 35, until the terrestrial stream lines coincide in direction with the wire 33.
