Abstract:
For use in loading heavy sticks of plastic pipe into a pipe fusion machine, a pipe storage rack with hydraulically powered pipe stick dispensers and stands allows sticks of pipe stored on the rack to roll gravitationally onto a rocking V-shaped dispenser cam disposed between the rack and the fusion machine loading path for one-stick-at-a-time loading onto powered track and roller stands which enable Cartesian manipulation of the stick into the fusion machine. The cam is adjustable to suit pipe stick diameters ranging from 20″ to 48″. Many sticks can be stored at one time, releasing heavy lifting equipment and operators to work elsewhere. The process requires only one operator using a pendant controller and the pipe sticks are handled by heavy equipment only when being loaded onto the racks.
Abstract:

Abstract:
An apparatus for curing cylindrical shaped elements having a liner, especially a liner of a rocket motor sleeve, where the cylindrical shaped elements are cured during rotation in a horizontal orientation. Horizontal rotation produces a liner with a substantially uniform thickness. The apparatus is mobile, compact, and has built-in robust safety mechanisms not compromised by the heat used to effect a cure. The cylindrical rollers are easily cleaned with minimal cross-contamination of one lot to another. Dripping of elastomeric materials from one assembly of rollers onto a stackable assembly of rollers below is eliminated. Each stackable assembly of rollers is independently controlled where each assembly is driven by its own motor, so rotation of one assemble does not affect another assembly of rollers.
Abstract:
Method and device for forming a continuous tubular foil (106, 308). Foil (106, 308) is supplied and buffered. Foil (106) is supplied as flattened tubular foil (106) from a supply. A next piece of foil (308) is supplied from a next supply. The ends of tubular foil (304, 309) are connected. This then allows supplying and buffering next tubular foil (308) supplied from the next supply. The device and method allow connecting the ends of tubular foils (304, 309) by opening the end (309) of the next flattened tubular foil (308) supplied from the next supply and moving the end of the flattened tubular foil (304) in an upstream direction (299) into the opened end of next tubular foil (309) from the next supply. Connection is made using a tape (250, 270) applied onto the foil ends (304, 309).
Abstract:
An apparatus for separating from a mandrel a shell snugly surrounding the mandrel has a base, a frame fixed on the base, and a holder on the base forward of the frame and adapted to support the shell surrounding the mandrel with an end of the mandrel juxtaposed with the frame. At least two stripper jaws on the frame can move radially of the mandrel of the shell on the frame between outer positions spaced radially outward from the shell and inner positions engageable with the shell. An extractor slide can shift longitudinally on the base rearward of the frame and carries a gripper extendable through the frame to grasp the end of the mandrel. The slide can shift the gripper axially away from the frame to brace the shell axially through the jaws against the frame and pull the mandrel out of the shell.
Abstract:
The invention relates to a process for producing pipe sleeves made of mineral wool for insulating pipelines or for reducing the sound level in pipeline systems, comprising the following steps: providing a nonwoven web (11) made of mineral wool which is provided with an uncured binder, winding up the nonwoven web (11) on a winding mandrel (2) of a winder, curing the binder. Here, at least one reinforcing layer (12, 13) is provided before the nonwoven web (11) runs into the winder, in such a way that during the winding the said reinforcing layer becomes a constituent part of the pipe sleeve produced as a result.
Abstract:
The subject invention relates to a method of applying the hydrocarbon barrier inside plastic fuel tanks. The plastic fuel tanks are supported on a carrier in an upright position for movement in a loop through inverted positions. While upright, hot and dry air treats the inside of the plastic fuel tanks followed by injecting SO3 inside the plastic fuel tanks through the nozzles. The SO3 is extracted from the plastic fuel tanks followed by injecting ammonia into the tanks through a second nozzle. After extracting ammonia from the plastic fuel tanks, the tanks are inverted and drained followed by a rinsing with a high pressured water and drying with hot air.
Abstract:
Installation for assembling tube components, particularly bodies (1) with shoulders, comprising the following elements arranged in succession: a linear body conveyor (4), a transfer system (7) designed to apply a change in orientation to the bodies (1) of about 90°, an assembly unit (8) for fixing the shoulders to the bodies (1), characterized in that the transfer system (7) consists of a device (9) for gripping the bodies and of a device (17) for changing the orientation of the bodies, the orientation-change device comprising a rotary conveyor (17), of the conveyor belt type, which is arranged at right angles to the direction of the linear conveyor (4), the said rotary conveyor (17) comprising a belt (18, 19) rotating about a direction that makes an angle of about 45° with the direction of the linear conveyor (4), the belt (18, 19) comprising elements (15) for grasping the bodies, the shape of which is designed so that the bodies (1) are initially grasped on one of the sides of the rotary conveyor (17), in a direction parallel to that of the linear conveyor (4), and that they undergo a change in orientation by 90° when they pass to the other side of the rotary conveyor (17).
Abstract:
An apparatus for restoring a necked-down end of a plastic core includes molding and curing stations and a core handling system having a carriage for sequentially positioning the core adjacent the stations. The molding and curing stations are heated and cooled, respectively, by heating elements and a chilled coolant. A core handling system includes a core-supporting carriage slidably supported on first rails for engagement between the core and the stations. The first rails are slidably supported on perpendicularly oriented second rails to provide for sequential alignment of the carriage with the molding and curing stations. A control system includes motor drives controlled by a programmable logic controller having a processor. Sensors communicate signals to the processor representing the position of the carriage with respect to the upper rails and the position of the upper rails with respect to the lower rails for actuation and control of the motor drives.
