Title: Improvements in apparatus having releasable closure and connecting elements
IPC: C23C10/12
Filed: 1938-03-01
Abstract: 512,666. Coating with metals. DAEVES, K., and BECKER, G. March 1, 1938, No. 6445. Convention date, May 11, 1937. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 2, 1938.] [Class 82 (ii)] In apparatus used at high temperatures, e.g., in high pressure apparatus where a very close fit is necessary, the releasable closure or connecting elements, e.g., bolts, screws, nuts, packing members and closure plugs, which are tightened when the apparatus is in use and subsequently released, are made of steel and the surfaces are rendered rich in chromium by treatment with a gaseous chromium carrier, e.g., by passing a current of chromium chloride gas over the surfaces which are heated to above 850‹C. The surface treatment prevents seizing and so facilitates the release of the connections or closures. The elements may be made of heat-resistant and corrosion-resistant steel alloys containing chromium, with or without other elements such as nickel, vanadium or tungsten, e.g., the chromium-molybdenum steels. The Specification as open to inspection under Sect. 91 refers to the treatment of iron articles and describes a method of introducing the chromium into the surfaces by packing the articles in a medium, e.g., a chromium chloride salt, which evolves a chromium-containing gas. It also describes the treatment of articles before they have been finally finished, a bolt of iron or steel alloy being roughly shaped, enriched with chromium, and then brought to its final dimensions and provided with the thread. This subject-matter does not appear in the Specification as accepted.

In a method of extruding a hollow metal member having an external annular flange spaced from the ends thereof, a cup-shaped blank having an annular wall which is outwardly thickened over a substantial portion of its length extending from a rim thereof is supported on its rim by an annular shoulder in a die and extruded by a ram so that a portion of the thickened part of said blank is forced through an annular space defined by the die wall and a mandrel which defines the internal shape of the port. A cup-shaped blank 16 formed from a circular blank of steel in two backward extruding operations is placed in the die aperture and the combined punch 9 and annular punch 8 press the blank downward to the position shown in Fig. 1, thus completing the forming of the blank interior. At this stage the base of the blank is firmly clamped between the punch 9 and a mandrel 4 carried by a sliding member 3 which is urged upwardly by springs 5. Continued downward movement of the compound punch and the mandrel 4 extrudes the portion 17 through an annular orifice 711 to form an article as in Fig. 2. Ejectors 11, 12 and 13 are provided respectively in the punch and die. Different articles which may be extruded by the method of the invention are described (Figs. 6, 7, 8, not shown), having various internal shapes as defined by suitable mandrels, and various ratios of tube wall thickness on either side of the flange.

In a moving coil microphone in which the moving coil 4, Fig. 1, is mounted between the resilient brim and a dome 1 of a diaphragm, and wherein the chambers adjoining the resilient brim are acoustically coupled through a passage, the acoustic impedance Z of the passage which may comprise a number of radial recesses 7 in the annular diaphragm seat 6 is at most as great as the net acoustic impedance Zb acting directly on the dome, this being that due to chamber 9 as modified by chamber 18 and its acoustic filling 14 and that due to the inlet apertures 20 and chamber 3. It is secondly stipulated that the acoustic impedance Zb should not exceed twice that of the annular air gaps between the moving coil and the yoke 10, and the moving coil and the core 11.
