Sealing of insert in plastics body

The invention provides a method of installing an insert in a plastics body so as to provide a screw thread therein, the insert being of metal and formed with the screw thread, and in which the hole in the plastic which receives the insert is sealed, by providing the insert with an 'O' ring located in an external peripheral groove and projecting therefrom, the size and shape of the insert and hole being related and selected so that in axial displacement of the insert into the preformed hole accompanied by softening of the plastic caused by the fastener being preheated or by vibrations applied to the plastic via the fastener as it is inserted, the 'O' ring only comes into contact with unsoftened plastic and only comes into contact with plastic towards the end of the axial installation movement. This ensures a good seal between the 'O' ring and the plastic.

Through-transmission welding of catheter components

A process for forming a heat weld between a catheter shaft and a surrounding balloon comprises selecting an elongate catheter shaft formed of thermoplastic polymeric material that is opaque to red and near-infrared light, and selecting a balloon formed of thermoplastic polymeric material that is transparent or translucent to red and near-infrared light. While a neck of the balloon is fitted in close contact around a distal portion of the catheter shaft, a laser beam of red and near-infrared light is applied through the balloon neck to impinge on the underlying opaque distal shaft, which is heated thereby. Heat from the shaft is conducted into the surrounding balloon neck so that adjacent annular portions of both components melt and mix. The molten materials are allowed to cool, forming a secure weld joint between the neck and the shaft. The process yields strong, flexible bonds between balloons and catheter shafts that may be selected from a wide variety of materials.

Apparatus for providing bottom blanks for containers in a manufacturing process

The present invention is directed to an apparatus and method wherein bottom blanks for containers are severed from a web feed roll and subsequently transferred at a compatible speed and spacing to final forming mandrels on which finished containers are to be formed. The bottom blanks are tangentially transferred from a first transfer turret at a final velocity and spacing most desirable for cutting and minimizing scrap to a second transfer turret at a second velocity and spacing and thereafter tangentially transferred to the final forming mandrels. Subsequently, preprinted rectangular blanks of longitudinally stretch-oriented foam sheet material formed into cylinders are transferred onto the final forming mandrels. Thereafter, the bottom blanks the cylindrical blanks and the final forming mandrels are heated to shrink the cylindrical blanks so that they assume the shape of the final forming mandrels. The top curl on containers such as drinking cups and food tubs is formed after shrink forming. Further, the bottom seam of the container is reinforced by ironing after shrink forming.
