摘要： An expandable core for casting concrete pipe is disclosed having a cylindrical core member with a longitudinal slot-like opening in its periphery. Core gate means and rigid links are pivotally interconnected and are mounted on the interior of the core member to straddle the slot-like opening. An overcenter linkage system is connected to the core gate means and driven by fluid or mechanical means to selectively expand the core member, simultaneously pivot the core gate into the slot-like opening and lock the core in this expanded position so that concrete may be cast therearound. To separate the core from concrete cast therearound, the fluid or mechanical means may be selectively operated to drive the overcenter linkage means so as to pivot the core gate means out of the slot-like opening and collapse the core.

摘要： Method of making reinforced concrete inclusive of hollow concrete body of tubular shape having beveled end and reinforcing member wrapped on exterior surface of length of concrete body at beveled end in progression of wraps to form continuous helical assembly. Reinforcing assembly under lesser tension extends along shorter side portion than longer side portion to provide more nearly equal stress in concrete body. Means associated with concrete body onto which reinforcing member is wrapped is utilized for holding reinforcing member against circumferential movement to maintain said preselected tension in reinforcing member.

摘要： A closed conduit has a liner for the crown thereof, the conduit being ordinarily subject to flow in the invert portions thereof of a liquid bearing a corrosive vapor or a vapor which is converted to a corrosive liquid. The liner is formed from a rectangular essentially planar corrosion resistant sheet of deformable material having memory characteristics causing the material to tend to revert to its undeformed condition. The sheet is deformed and constrained to define a tube having a diameter less than the diameter of the conduit, and is inserted into the conduit. Structure is disposed within the conduit adjacent at least to one side of the flow line thereof to engage the longitudinal edge of the sheet and restrain the edge in position upon release of the constraint of the sheet, so that when the sheet returns to its undeformed state to line the crown of the conduit, the corrosive action of the vapor is not manifest against the crown portions of the conduit.

摘要： Wheeled vehicle with body including forward and rear upright support members in superposed relation to wheels and associated lift mechanism mounted on at least one of said members. One upright member movable forwardly and rearwardly on body to dispose associated lift mechanism in different working positions including a cradled seating position for the load on the body in superposed relation to the wheels, thereby permitting rapid transport of cradled load in balanced relation on vehicle, and a counterbalancing of vehicle weight to load when raising or lowering load. Also disclosed is a wheeled vehicle having an extendible load cradling structure. This vehicle includes a lift mechanism for lifting a heavy object from a ground support and the load cradling structure is selectively extendible to a position for receiving the lifted heavy object.
