Abstract: A method is proposed in which tubes or similarly shaped packaging containers having a cylindrical body of an extruded tube of thermoplastic material can be widened in order that they can be inserted one in the other - as already known in the case of metal tubes - and thus be stored and transported in a space-saving way. The tube 1 is pressed by means of an upper tool 3 onto a heated mandrel 2 and thereby widened conically. It is then heated by means of infrared radiators 4 and then cooled on the mandrel. In this way, in spite of the unavoidable recovery, adequate widening of the tube walls can be accomplished in a reproducible manner. <IMAGE>

Each floor is selectively responsive to a driven axle (71) and comprises low friction rails (80) on opposite sides of the confinement area; a chain (75, 76) rides and movable longitudinally along each rail. A plurality of spaced support bars (83) extend between the chains and a flexible floor material (87) extends between and is supported in trampoline-like fashion on the support bars. The floor material comprises an open-weave fabric with apertures (89) through which droppings can easily pass. Each cage tier includes an access door (120, 130) pivotal about a horizontal axis (133) located between the upper and lower edges (131a, 131b) of the door. The pivot axis is located below the inoperative position of the floor (87) immediately above the door so that when the door is opened to a horizontal position, the upper floor can be moved into and out of its inoperative position, and when the door is closed, poultry cannot escape over the door. The broiler cage further comprises a single motor-driven shaft (112) and a clutch (121) for selectively driving each floor with the same motor.

Abstract: A telescoping landing gear shock strut set (3, 4, 5) which can provide both the main landing gear and auxiliary landing gear function, and which is affixed to and extendable from an aircraft, is restrained in an unenergized, compressed condition. A high pressure gas charge is then provided between the extendible element (12) of the strut and the element affixed (11) to the aircraft. Early in the takeoff run, the charge gas in the forward strut is released so as to jump the nose and rotate the aircraft to a high: angle of attact appropriate for takeoff. Subsequent to this rotation, but before the conventional takeoff speed is reached, the charge gas in the main strut is released to impart a vertical velocity to the entire aircraft (1), thus jumping into the air. 
     Both the forward strut and main struts incorporate a hydraulic flow bypass function, so that the landing shock absorption function does not compromise the aforesaid energy release, the struts also incorporate values to discharge enough residual gas immediately at the end of the jump stroke so-than the landing energy absorption mode is not compromised. Following the main gear jump, the continuing horizontal acceleration provided by the propulsion engines (10), and continuously weakening vertical acceleration comprising gravity diminished by the wing aerodynamic lift, which is increasing with speed results in an initially upward aircraft trajectory which does not return to earth. A takeoff run with the aforesaid jump action is considerably shorter that the takeoff run without the jump function. Although the jump takeoff speed is less than the conventional takeoff speed, and there would be a lift shortage in a straight flight path, the centrifugal acceleration produced by the bending downward of trajectory, which is initially inclined upward, compensates for this temporary lift shortage.
