Abstract: "IMPROVEMENTS IN OSCILLATING REED AND METHOD"      ABSTRACT      There is disclosed improvements in oscillating reeds particularly for use in generating a sweeping or oscillating air flow pattern.  The oscillating reeds of this invention are constituted by a plurality of spaced apart resilient reed elements which, prefer-ably, are made from graphite fibers bonded together by an epoxy resin matrix reinforced by a scrim of fiber glass.  To minimize the effect of torsion and/or forces which can cause the reed elements to buckle and hence create noise, a plurality of undulations are formed in the graphite strip.  Thus, the oscillating reed accord-ing to the present invention offers the following four major advantages, (1) reduction in noise from buckling, (2) amplitude modulation, i.e. oscillation amplitude insensitivity to wide ranges of flow rates     (3) easier starting of oscillation, and, (4) improved fati-gue strength.

Abstract: ABSTRACT OF THE DISCLOSURE    A method of producing thin sheet glass by the float process, in which molten glass is formed into a thin layer on the surface of molten metal by making molten glass pass through a vertically narrow gap given by a sluice wall which extends above and transversely of the molten metal bath, and the molten glass layer is stretched to further reduce its thickness.  By forming the sluice wall with a slant surface on the front side facing a pool of molten glass so as to smoothly introduce the molten glass into the gap beneath the wall and by using a practically isotropic graphite which is not greater than 23% in its porosity as the material of the sluice wall, defectless sheet glass thinner than 1 mm can be obtained.  Preferably the porosity of the graphite is at least 9%.  For the quality of the sheet glass, it is favorable to form the sluice wall with a vertical surface on the rear side and another slant surface which interposes between the lower edge of the slant front surface and the lower edge of the vertical rear surface to allow the molten metal beneath the wall to smoothly raise its level from a lowered level beneath the molten glass pool.

Abstract: ABSTRACT OF THE DISCLOSURE      A method is disclosed of applying glue to loose fibrous material which is revolved relatively rapidly in a confined space.  While this is happening, the glue and air under slight excess pressure are fed to the material from approximately the centre of the space.  Apparatus for this purpose comprises a container, a hollow shaft rotatably mounted in the container, and a plurality of rod-like tools secured to the hollow shaft.  Each of the tools is generally cylindrical, and is provided with a central longitudinal bore one end of which opens into the hollow shaft and the other end of which is closed.  Each tool has a longitudinally-extending flat external surface portion, and a plurality of substantially radial bores communicating with the central longitudinal bore. The radial bores of each too terminate at the external surface of that tool in the zone of said flat portion thereof. Thus, glue can flow through the hollow shaft and be broken down into droplets as the glue is flung out of the radial bores of the tools by the centrifugal force caused by rotation of the hollow shaft.

Abstract: ABSTRACT A nonmagnetic austenitic nickel base alloy and articles made therefrom containing   and the balance nickel plus incidental elements.  The alloy is characterized by a 0.2% yield strength of at least 1241 MPa (180 ksi) in the as forged and heat treated condition without the requirement for cold working.  The alloy provides large steam generator retaining rings having improved properties.                 SPECIFICATION         This invention relates to a high strength austenitic nickel base alloy and, more particularly, to such an alloy and nonmagnetic parts made therefrom having high strength with a unique degree of toughness and freedom from segregation.          As brought out in U.S. patent No. 3,935,037 granted on January 27, 1976 to D. R. Muzyka and R. C. Gebeau (one of the joint inventors of the present invention) and assigned to the assignee of the present application, it has long been sought to increase the strength of large nonmagnetic austenitic parts of relatively large cross section.  While the alloy of the 3,935,037 patent made available an alloy capable of attaining a 0.2% yield strength (Y.S.) of at least 1241 MPa (180 ksi) with significantly less cold work than had thereto-fore been required, there nevertheless remains a demand for an alloy which is capable of providing such parts without the need for cold working and which are nevertheless capable of meeting the requirement of a 0.2% Y.S. of 1241 MPa (180 ksi) with adequate toughness and without the need for any cold work.          U.S. patent No. 3,046,108 granted on July 24, 1962 to H. L. Eiselstein discloses a broad range of nickel or nickel-cobalt base nonmagnetic austenitic alloys which was designed to assure a minimum 0.2% yield strength of 690 MPa (100 ksi) combined with high stress rupture strength at elevated tempera-tures, e.g. temperatures of about 1200-1350 F (about 650-730 C).
