摘要： A gas spring comprising a cylindrical body (10) having a base wall (11) and an integral side wall (12) with an open upper end defining a bore (13). The bore (13) includes a lower cylindrical portion (14) and an upper cylindrical portion (15) of greater diameter than the lower cylindrical portion defining a shoulder (16). A piston (18) of constant diameter is positioned in the bore (13) and has a radial flange (19) on its lower end with a wear bearing (20) contacting the lower portion (14) of the bore. An annular retainer (21) is positioned on the shoulder (16) and is adapted to be engaged by the flange (19) on the piston (18). An annular end cap (22) is threaded in the upper cylindrical portion (15) of the bore (13) and maintains the retainer (21) against the shoulder. An annular lock nut (23) is threaded in the upper portion (15) of the bore (13) and locks the end cap (22) in position. Circumferentially spaced radial openings (34) are provided adjacent to the periphery of the lock nut for venting gas during disassembly if any gas remains. A charging valve (38) and a rupture plug (43) including pressure relief disc (44) are provided in the base wall (11). In one form, the gas spring includes a plurality of longitudinal spaced annular ribs (55,56,57,60) which provide heat dissipation.

摘要： A machine for corrugating lengths of continuous strip stock (16) that includes first and second sets of corrugation-forming rollers (28, 30, 32, 34) for receiving strip stock from associated coil rolls and feeding corrugated stock to vertically spaced slots (62, 64) in a shared cutting station (40). The running length of each corrugated strip is measured and the cutting station (40) is controlled so as to obtain severed stock sections of predetermined lengths, which may be variably programmed (44, 54) in a predetermined sequence. The cutting station (40) includes a stationary plate (60) having vertically spaced strip-receiving slots (62, 64) and a pair of shear blades (76, 80; 78, 82) integrally formed on a shear plate (66) selectively driven by the machine controller through a cycloidal drive mechanism (84, 86).

摘要： A gas cylinder control system for use with machine systems such as die stamping systems that includes at least one gaseous fluid cylinder (10) associated with the machine system, gaseous intensifier control cylinder (16) normally operated in timed relation to the gaseous cylinder (10) and a passage (20) providing communication between the gaseous cylinder (10) and the gaseous intensifier control cylinder (16). The gaseous intensifier cylinder (16) operates at substantially higher pressure than the die cylinder (10). A normally closed control valve (15) is provided in the passage (20) and is operable to open the passage (20) in time relation to the operation of the machine system in order to apply the higher gaseous pressure of the gaseous intensifier cylinder (16) to the gaseous cylinder (10) and lock the gaseous cylinder and prevent it from moving until the control valve (15) is actuated to close the passage (20) thereby providing a predetermined time delay.

摘要： A cut-off machine and method adapted to be positioned downstream from a source, such as a tube mill, for receiving a moving length of tube stock (19) from the mill and severing plural predetermined lengths from the moving length. The machine may comprise a plurality of cut-off assemblies (23) that are reciprocated longitudinally of the moving length of material and operated during the movement of sever plural predetermined lengths. Each cut-off assembly comprises a cutter blade (80) that is supported for movement in an arcuate path and for radial movement. A cam (90) in the path of each blade is engaged by a cam follower (92) moveable with the blade to cause the blade to move in a straight line transversely of the flattened tubing while severing the tube length.

摘要： A high pressure condenser (20) comprising a plurality of transversely spaced flattened tubes (21) having their ends extending into headers (23) at each end to the tubes and a plurality of undulating fins (22) extending between adjacent tubes. The tubes are made by utilizing flat strip stock that is coated on both surfaces with a coating that will fuse and bond on the application of heat and has a plurality of longitudinally and transversely spaced deformed portions or projections (25). The flat strip stock is subjected to the steps of first rolling the opposite edges of the strip into a curved configuration having a radius corresponding to the radius of curvature desired on the rounded longitudinally welded edge of the tube, then progressively rolling the central portion of the strip into the rounded configuration desired along the other longitudinal edge of the tube (21) while utilizing the rounded free edge portions and the center bend to accurately center the strip as it advances through the successive forming rolls and, thereafter heating the spaced free edges of the rolled strip to a temperature at which they are adapted to be fused together and directing them through a guide located upstream from and directly adjacent a pair of squeeze rolls for effecting a weld seam therebetween, the guide being designed to engage each free edge portion of the strip on laterally opposite sides thereof. The projections (25) in the strip are brought into engagement before the free edges of the rolled strip are fused together. When the tubes (21) are assembled with the fins to the headers (23), the entire assembly is subjected to heat to cause the coating on the surfaces of the tubes to bond the projections to one another and to bond the exterior of the tubes to the slots in the headers (23) through which the ends of the tubes extend.
