Abstract: Aluminum base powder metallurgy alloy article having an improved combination of high-transverse yield strength and high-stress corrosion cracking resistance. The alloy contains the basic precipitation hardening elements zinc, magnesium and copper plus dispersion strengthening elements iron and nickel. It may additionally contain chromium and/or manganese. The alloy is prepared by atomization of a melt of the elements, hot-working, solution heat treating, quenching and artificial aging. Components of the alloy in percent by weight are, in addition to the aluminum, from at least 6.5 to 13 zinc, 1.75 to 6 magnesium, 0.25 to 2.5 copper, 0.75 to 4.25 iron and 0.75 to 6 nickel, up to 3 manganese and up to 0.75 chromium. The iron to nickel ratio is from 0.2:1 to 2.0:1.

Abstract: This disclosure describes a method for forming a sheet metal joint for attachment of a pull tab to a tear strip in a container end closure in which a bubble is first formed in the closure end panel, the bubble is reformed into a hollow rivet having a substantially cylindrical sidewall and an arcuate transverse end wall, and the rivet is staked or upset to compressively fold the transverse end wall thereof to form a head on the rivet which is at least as thick as the transverse end wall of the unstaked rivet.

Abstract: In a window assembly having an outer frame within which inboard and outboard lapping sashes are mounted for horizontal or vertical relative movement, the outer frame includes interior and exterior metal frame members and a rigid plastic or other nonmetallic thermal barrier member therebetween connecting the metal frame members in thermally insulated relation to each other, each sash includes an inner frame embracing the periphery of a glass or other panel and constituted by a metal frame member and a rigid plastic or other nonmetallic thermal insulating frame member respectively defining the entire opposite lateral surfaces of the frame, and the inboard and outboard sashes have their insulating frame members at their exterior and interior sides, respectively, so as to be adjacent to the thermal barrier member of the outer frame. The insulating frame member of each sash desirably includes a web or webs defining the respective lateral surface of the sash frame and flanges extending therefrom and having free marginal portions interlocking with the metal sash frame member to substantially space the latter from the web and to cooperate with the web and the metal frame member in defining cavities therebetween.

Abstract: 1,203,525. Perforating elastomeric articles. ALUMINUM CO. OF AMERICA. 22 April, 1969 [26 April, 1968], No. 20611/69. Heading B5A. A method of piercing holes in elastomeric articles of predetermined shape includes placing articles in a predetermined orientation and then moving them into and out of a predetermined position with respect to a laser, and upon moving each article into such position actuating the laser to produce a laser beam firing through said position to pierce a hole at a desired location in the article. Bottle nipples are fed from a vibrating hopper to a device 12, Fig. 2, which locates each nipple 72 in an individual support 16 mounted on a continuous, intermittently driven chain, which feeds the nipples in their supports to a piercing head 20. The latter comprises a gas-tight compartment 31 into which a laser beam 34 is directed when a nipple is correctly located and orientated in its support; photo-electric means 58, 60 sense improper orientations to prevent operation of the laser. The beam is divided by an optical wedge 32 into three beams 36, 38, 40 directed on to the nipple to provide vent holes 68, 70 in the nipple base and a feed hole 72. Beam detectors 62, 64, 66 operate to stop the apparatus if the centre beam and at least one of the side ones are not received by them, i.e. indicating whether the desired holes have been pierced. The perforated nipples on their supports are fed to a means such as an air jet which ejects them into a delivery shoot or conveyer. An improperly seated nipple is not perforated or removed from its support and is recirculated.
