A new lightweight bladed rotor for gas turbine or turbojet engines combines an inner support ring with blade straps made of fiber reinforced material. The blade straps wrap halfway around the inner support ring so that their ends extend radially outwardly to form blade pairs. A rim connects the blade straps near their ends to provide rigidity and to define a flowpath.

The invention provides a method of forming a pre-wrapped gift package which appears to be hand wrapped. It includes forming a sheet of box material with affixed decorative paper into a flattened box tube. The box material is provided with flaps so that a consumer may erect the tube into an open box and use the flaps to form end closures. A volume sizer is provided in the form of creased box material which, when erected, provides an illustration of the volume made available when the pre-wrapped g...

An element for treating a fluid flowing through the element which comprises at least two filter medium layers helically wrapped around a pervious, hollow tube, with the filter medium layers forming an overall graded pore structure for the fluid treatment element and/or at least one diffusion layer positioned between the filter medium layers.

Apparatus for manufacturing a spindle-shaped wrapped food (10) by squeezing both end portions of a cylindrical wrapped food (10A) having an extra portion at each end of a membraneous food (12) with a filling member (11) enwrapped therein using an apparatus including an endless conveyor device (20) having a mechanism for pushing up an endless belt (21) with both edges thereof inclined, a stationary resistance plate (23) juxtaposed along and above the endless belt (21) of the endless conveyor devi...

The present invention provides a method of forming a pre-wrapped gift package which appears to have been hand wrapped. The method includes forming a sheet of box construction material with decorative paper affixed thereto into a box tube by joining ends thereof. The box construction material is properly creased and provided with flaps so that a consumer may fold the flattened box tube into a box so that the end flaps form ends of the box and the decorative paper forms a pair of paper flaps which...

A stretch wrapped and roped package for heavy loads such as cylindrical coils of metal, paper or the like that includes a skid supporting the load. A friction layer on the top of the skid and another friction layer on the bottom of the load which is covered by an overwrap of protective material such as plastic or paper. The skid is especially designed to reduce risk of damage to the stretch wrap roping that holds the skid onto the bottom of the load.

An air bag (12) for restraining an occupant (14) of a vehicle (16) has a deflated condition and an inflated condition. The air bag (12) has layers (20, 22) defining between them an inflation fluid volume (18) into which inflation fluid is directed to inflate the air bag. A fluid impermeable wrap (140) encircles the air bag (12) when the air bag is in the deflated condition. The wrap (140) has fluid inlet openings (190, 192) for receiving inflation fluid and for directing inflation fluid into a p...

A radiopaque tube for use as a medical catheter is provided. The tube is preferably formed about a wire mandrel which is subsequently removed to form the lumen of the tube. The tube includes an inner wall layer made from a polymer resin defining the lumen. A spiral wound reinforcement layer of a radiopaque material is wound about the inner wall layer. The spiral wound layer can comprise flat wire or a multiple strands wound about parallel to each other. A polymer resin outer wall layer is laid o...

A multifilamentary stabilized superconductor of the A-15 type is disclosed wherein the A-15 compound is formed on rods of niobium or vanadium by diffusion of tin or gallium, respectively, from a copper alloy matrix and wherein stabilization is provided by an external layer of copper. The stabilizing copper is protected from tin or gallium diffusion by a number of spirally wrapped layers of tantalum separated from one another by copper layers.
