Abstract:
A gas delivery system (10) delivers a shielding gas from a source (16) through one or more hoses to a torch (12) having a nozzle (18) during welding of a workpiece (25). A shielding gas controller (56) includes an inlet (62), an outlet (64), and at least one valve (60) between the inlet (62) and the outlet (64). The valve (60) operates in response to a predetermined minimum shielding gas flow set point. The shielding gas controller (56) operates the valve (60) before or after a weld (32) to change the flow of the shielding gas according to the predetermined minimum shielding gas flow set point. A method of welding includes predetermining a flow rate of a shielding gas, predetermining another flow rate of the gas, dispensing the gas at the first flow rate proximate a first weld pool (26) during welding, and dispensing the shielding gas at the second flow rate, different from the first flow rate, during welding of another weld (32) on the workpiece (25).

Abstract:
A film dispenser (12) for stretch wrapping machines(10) includes at least one roller (18) and a first brake (42) engageable with a braking surface (52) the one roller. The first brake (42) may include a flat brake pad (62) that is pivotally movable for engagement with the braking surface (52), and is adjustable between a first configuration engaged with the braking surface (52) and applying a first braking force, and a second configuration disengaged from the braking surface (52) or only minimally engaged with the braking surface (52) such that any braking force applied is substantially less than the first braking force. A supply roll (18) support for a film dispenser (12) includes an elongate post (32) sized to receive a roll of film (14) thereon, and a pliable sheet (160) coupled with the outer peripheral surface (150) of the post (32) and extending around at least a portion of the outer peripheral surface (150).
Abstract:
A turntable assembly 100 for a stretch wrapping machine comprises a frame 120, a hub 104 rotatably mounted to the frame 120 on a shaft 132, a turntable 102 mounted to the hub 104, and a plurality of rollers 1 10 rotatably mounted to the frame 120 defining a generally horizontal supporting plane for the turntable 102. Each roller has an axis of rotation generally parallel to the supporting plane and generally passing through the turntable axis of rotation 140. The frame 120 is constructed so as to elastically deform, upon a load 16 being placed upon the turntable 102 that results in the load 16 not being evenly supported by the rollers 1 10, to permit the roller axis of rotation to tilt relative to the horizontal supporting plane while still passing through the turntable axis of rotation 140.
Abstract:
A turntable that can be used with a machine for wrapping loads with packaging material (13) includes a turntable assembly (100) having a first support assembly (116) and a load support surface (102) supported for rotation on the first support assembly (1 16). A second support assembly (122) contacts a floor surface (120), and a plurality of load cell assemblies (124) disposed between the first and second support assemblies (116, 122) space the first support assembly (116) and the load support surface (102) above the floor surface (120). In use, the load cell assemblies (124) sense a weight of a load (16) on the load support surface (102).
Abstract:
In one aspect, an elevating conveyor (10) includes a vertical elevating member (26) having a helical flight (30) and a tubular barrel (32) surrounding the elevating member (26). The tubular barrel (32) is rotatable relative to the elevating member (26) and is directed toward a centered position with respect to the elevating member (26) by a centering assembly (70). In one embodiment, the centering assembly (70) includes a plurality of rollers (72a, 72b, 72c) spaced circumferentially around the barrel (32) and being movable in directions toward or away from the barrel (32). In another aspect, the conveyor (10) has a modular construction that facilitates storage, transportation, and assembly of the conveyor (10) in various heights. The elevating conveyor (10) may further include a dust tube (112) surrounding the barrel (32) and defining a chamber (120) therebetween. An end cap (114) extends over and is spaced from the second end (112b) of the dust tube (112) to define a gap (118) through which dust generated by operation of the conveyor (10) is drawn into the chamber (120).
Abstract:
A two-stroke engine (10) includes a crankshaft (12) that is rotatable about an axis (14), and an engine block (20) that includes a combustion cylinder (28) and a compression cylinder (26). A first piston (38) is slidably disposed within the combustion cylinder (28) and is operatively coupled to the crankshaft (12) for reciprocating movement within the combustion cylinder (28) through a power stroke during each rotation of the crankshaft (12) about the axis (14). A second piston (36) is slidably disposed within the compression cylinder (26) and is operatively coupled to the crankshaft (12) for reciprocating movement within the compression cylinder (26) such that fresh air is received and compressed in the compression cylinder (26) during each rotation of the crankshaft (12) about the axis (14).

Each master cylinder assembly includes a master cylinder piston (32) slidably movable by actuation of a respective brake pedal (18a, 18b) to and between an active position and an inactive position. A spool (74) slidably disposed within a piston bore (70) of the master cylinder piston (32) is operable in a first mode to direct hydraulic fluid from a quick-fill chamber (62) to a master cylinder chamber (50) at a first pressure upon initial movement of the master cylinder piston (32) from the inactive position toward the active position. The spool (74) is operable in a second mode to direct hydraulic fluid from the quick-fill chamber (62) to a tank (20) when pressure in the master cylinder chamber (50) reaches a predefined threshold.
