Abstract: A method and apparatus for spin flow necking-in a D&I can (C) is disclosed wherein an externally located free spinning form roll (11) is moved radially inward and axially against the outside wall of the open end of a trimmed can (C). A spring loaded (20) interior support slide roll (19) moves under the forming force of the form roll (11) as the latter slides along a conical forming surface (24e) of a second free roll (24) mounted axially inwardly adjacent the slide roll (19). To minimize the plug diameter variation between successively necked cans (C), the axial retracting movement of the slide roll (19) is halted at a predetermined location via contact with a spacer (1025) to prevent further radial inward movement of the form roll (11) which would otherwise occur as a result of only cam controlled form roll movement.

Abstract: A method and apparatus for spin flow necking-in a D&I can (C) is disclosed wherein an externally located free spinning form roll (11) is moved radially inward and axially against the outside wall of the open end of a trimmed can (C). A spring-loaded (20) interior support slide roll (19') moves under the forming force of the form roll (11) as the latter slides along a conical forming surface (24e) of a second free roll (24) mounted axially inwardly adjacent the slide roll (19'). To prevent damage to the metal caused by excessive pressure contact between the form and slide rolls, the slide roll (19') is axially retracted via a cam ring (102) which initially contacts the form roll (11) during radially inward necking movement.

Abstract: An apparatus is disclosed for regulating a liquefied gas input stream for temperature and pressure. The apparatus produces a pressurized head of liquefied gas while removing gaseous material to produce a constant temperature and pressure liquefied gas exit stream.
The apparatus comprises a chamber (15) having an inlet (12) for liquid gas and a gas exhaust 30, toward the upper end of the chamber and a column (22) opening from the lower end of the chamber, the lower end of the column being in communication with an outlet (26) and with the lower end of a tube (28) which surrounds the column and opens into the lower end of the chamber. The chamber is provided with a float (18) which controls the liquid level within the chamber.

Abstract: A multi-station machine (10) for necking-in the open end of a metal container body (C) includes a plurality of necking spindle assemblies (18) mounted at circumferentially spaced locations on a tooling disc turret (12) in coaxial alignment with corresponding base pad spindle assemblies (20) mounted to a base pad turret (14). The turrets are co-rotatable with a main turret shaft (16). Cam controlled tooling activating assemblies (200) are mounted on the tooling disc turret (12) to control the necking-in movement of an eccentric roll (88) and an external forming roll (40) in each necking spindles in synchronism with delivery of vacuum suction through the base pad spindles which clamps the container bottom walls to the respective base pads. A sequential latching arrangement associate with the tooling activating assemblies prevents tool-to-tool contact between the outer forming rolls with the eccentric rolls in the absence of container bodies on station. The vacuum manifold arrangement feature the supply of high volume, low suction vacuum to a small number of stations in the vicinity of the infeed location to rapidly locate the container bodies on the base pads. A low volume, high suction vacuum supply to the downstream spindles ensures proper clamping suction to properly maintain the containers on the base pads during necking. In the absence of containers at various stations, the high volume, low suction vacuum is subject to leakage only at a small number of stations at the infeed while vacuum leakage in the remainder of the stations is insufficient to lower clamping pressure to unacceptable levels.
