Title: Process for making stainless iron or steel alloys
IPC: C22C33/02
Filed: 1933-08-18
Abstract: Stainless iron or steel alloys are made by intimately mixing finely divided metallic iron with finely divided chromium powder in an amount adapted to impart the desired stainless quality and the desired amount of carbon powder, the metal powders having clean metallic surfaces, moulding the mixture under pressure and subjecting the compressed powders to a non-oxidizing heat treatment at a temperature substantially below their melting points, e.g. above 900 DEG  C., but below 1200 DEG  C., to bring them to their bonding point to form a substantially homogeneous product. If an alloy also containing nickel is desired, the necessary amount of nickel powder is added to the mixture before moulding. The powders should pass through at least a 200 mesh screen, and the moulding should be carried out at a pressure of not less than 20,000 lbs. per sq. in. so that a product of predetermined density and porosity is obtained.  A liquid binding agent, e.g. water or nitrocellulose may be incorporated with the mixture of powders and the mixture extruded to form the desired article, e.g. tubes or wires, instead of being moulded.

Title: Underwater mining apparatus and method
IPC: E21B15/04
Filed: 1969-05-07
Abstract: 1,214,435. Underwater mining systems. WESTINGHOUSE ELECTRIC CORP. 7 May, 1969 [31 May, 1968], No. 23270/69. Heading E1F. To permit of satisfactory underwater mining by a ship-towed scoop, the scoop is secured to the lower end of a conduit that is inclined to the vertical and has been formed by the successive joining together and paying out of conduit sections from the ship as the ship is kept underway during the lowering of the scoop therefrom. The conduit passes through a gimbal mounting in the ship, which gimbal mounting allows the conduit to assume, with respect to the vertical an angle that is dependent on the speed of the ship through the water. For the handling of conduit sections there is provided a ship-borne derrick, which, in use, is tilted at the same angle to the vertical as that made therewith by the conduit so that a derrick-guided conduit section can, when required, be added to the conduit, which can either be held in or be axially slidable of the gimbal mounting as required. When a so formed conduit of sufficient length has been passed out of the ship, slowing down of the ship allows of placing the scoop on the submerged bed of material to be collected by the scoop as the inclination of the conduit to the vertical changes. The conduit may serve as a suction pipe to permit of removal from the scoop of material collected therein.
Patent GB-598784-A (GB)
Title: Improvements in or relating to abrasive tools and the manufacture thereof
IPC: B24D18/00
Filed: 1945-09-10
Abstract: 598,784. Making files. DAVIES, G., and WERTHEIMER, H. Sept. 10, 1945, No. 23272. [Class 83 (ii)] [Also in Group XXIII] An abrasive tool is made by forming pits or depressions in a metal surface which is then coated electrolytically with a hard metal such as chromium applied at such current density as to build up a series of nodules around the pits or on the raised surface between them which are then broken off so as each to leave exposed the broken and highly abrasive surface of the nexus by which it was joined to the base metal. The pits or depressions can be produced mechanically, chemically or electrochemically ; the surface can be hardened before plating by heat-treatment, rolling, drawing or swaging, the hardening being performed before or after the pitting. In one example, a steel disc is rendered abrasive at its rim by heattreatment, plating with chromium and breaking off the globules. In another example, steel rod strip or wire is hardened by rolling, drawing or swaging ; the surface is then pitted electrochemically or chemically, as e.g. by dipping in strong hydrochloric acid, rinsing and exposing to an atmosphere charged with nitric acid fumes. This is stated to result in approximately round pits ; a grain can be obtained in the surface by alternating exposure to the nitric acid atmosphere with exposure to liquid hydrochloric acid, the latter treatment being stated to produce linear pits or to convert round pits into linear or vermiform pits. Alternatively, the pitting may be performed mechanically, e.g. by vibratory steel needle points or a rotating chain mop, the links of which have rasplike projections. The surface is then rapidly plated to produce globules which are broken off, e.g. by means. of a stiff wire brush or by scraping with a hard metal edge. The brokenoff particles may be used for pitting softer metals by pressing or rolling them into the surface and then scouring them off. Brushes may be made from drawn steel wire rendered abrasive as described above. According to the Provisional Specification, tools for use in dentistry may be made in accordance with the invention.

[Class 13.] Relates to an electromagnetic horn, more particularly for motor vehicles, in which an armature secured to a diaphragm and free of any guide is subjected to a magnetic pull in the direction of the axis of the diaphragm and consists in an arrangement i n which the flux passing into the armature at its end remote from the diaphragm passes out of it into a yoke to close the flux path, the yoke having a web portion which lies considerably nearer the diaphragm than the end of the armature. As shown, a diaphragm c is clamped between the two parts a, b of a casing and has a corrugated metal disc e and cylindrical armature f secured to its centre by a unit d. The end of the armature is preferably disposed at a distance from the diaphragm at least equal to one-sixth of the diameter of the diaphragm and its cross section at the most should be one-third of the diameter of the diaphragm whilst the seat of the armature attachment of the diaphragm is at least one-sixth of the diameter of the diaphragm. During operation the outer end of the armature strikes against the end of a magnet core g which is surrounded by a coil h and is riveted together with an iron disc i to the casing lid a. Radial longitudinal slots k are provided in the armature f and core g so as to reduce eddy current losses. The iron path from the core to the armature is completed by a yoke member l which is welded to the lid a and is provided with a central opening for the passage of the armature and a lateral recess for an interrupter spring m. The armature has an annular groove n where it passes through the yoke l and the part lying between this groove and the diaphragm is increased in diameter to form a flange which operates the interrupter spring m. If desired, the parts may be so adjusted that no actual striking occurs between the armature and core.
