摘要： A transparent, coextruded mutilayered polyolefin film which can be sealed on both sides and having a base layer essentially comprised of a resin-modified propylene polymer and top layers essentially comprised of sealable olefin polymers. At 120.degree. C., the multilayered film has a shrinkage in the longitudinal direction of more than 7% and a shrinkage in the transverse direction of more than 5%. The base layer of the film is essentially comprised of a peroxidically degraded propylene polymer, with the degradation factor A being in the range of 3 to 10, and it contains 5 to 25% of a hydrocarbon resin. The top layers of the multilayered film are essentially comprised of a random ethylene/propylene copolymer having an ethylene content of 2 to 8% by weight, a distribution factor V.sub.F of more than 8, and a thermooxidation temperature T.sub.OX of more than 230.degree. C. The film exhibits a surface gloss (angle of measurement 20.degree.) of more than 100 and a haze (measured on four superimposed film plies) of less than 22%.

摘要： A method and apparatus for producing hollow plastic articles are disclosed. The articles have a blow-molded portion and a compression-molded portion, and are formed by downwardly extruding plastic at at least one extrusion rate to progressively form a parison having a downwardly facing open end from a first location adjacent an extrusion head toward a second location axially spaced therefrom. A male mold member is provided at the second location. Portions of the open end of the parison are engaged by a plurality of fingers, while the open end travels toward the second location and the engaged portions are moved downwardly at a rate at least corresponding to the extrusion rate. During the travel toward the second location, portions of the open end are radially expanded and guided over the male mold member. The parison is enclosed in a hollow mold having a molding surface corresponding to the blow-molded portion of the hollow article and having a second portion having a molding surface corresponding to the compression molded portion of the hollow article and cooperating with the male mold member. Air is admitted to the interior of the first portion to form the blow-molded portion.

摘要： A bag (1) for use in the shaping of liquid food products or stimulants consists of two plastics foils (2, 3), which are welded together in such an area of the two foils as will provide a plurality of interconnected mould cavities (4) with a common inlet (5). In the mould cavities (4) there are placed sticks (6) which are held in position by the positioning in a channel (8) having a length and cross-section corresponding to the holding part (7) of the stick (6). When the bag is filled with liquid ice cream or a similar material, the mould cavities (4) are distended three-dimensionally, and when the length of the sticks (6) is suitably dimensioned with respect to the length of the mould cavities (4), the sticks will be firmly "fixed" within the mould cavities (4). The sticks (6) are therefore placed in the middle of the ice lollies formed after freezing.

摘要： A method of making injection moulded plastic objects with one, two or three imbedded decorative and/or descriptive prints comprises the steps of placing the prints on relatively thin foils (4, 5) of an extent corresponding to the cross-section of the mould cavity (6), and placing the foils (4, 5) in the mould cavity (6) with respect to the runner (3) so that the foils are pressed into engagement with the bottom and/or top of the mould cavity by the moulding material injected under pressure.Thus, a plastic object with imbedded colored motifs at both the top side and the underside can be made by just one moulding operation.

摘要： A method of making an inexpensive injection molded propeller for mounting on a drive shaft. The drive shaft is attached to the hub of the propeller by a chemical and thermal shrink fit and by deformation due to the rotational forces of the propeller thereby producing a positive locking hub on the drive shaft. The propeller may be used, not only for remote piloted missiles and aircraft, but can also be used with different types of boat inboard and outboard drives, vehicles and equipment requiring a propeller having a positive locking system for securing the propeller or the like to the drive shaft.

摘要： A method for molding an annular lip type shaft seal 10 of the type having an annular elastomeric shaft seal element 12 and a resin liner 14 (preferably polytetrafluoroethylene) integrally molded therewith and bonded thereto, including providing a step or shoulder 36 on the mold core 26 to prevent the resin liner 14 from flowing axially beyond a predetermined location during molding. The method includes providing a certain range of acute angles ".alpha." between the shoulder surface 42 and the liner forming surface 38 of the mold core surface 34, and a certain range of shoulder heights "d" relative to the liner thickness "t", for various values of the initial viscosity of the elastomeric preform 18. The percentage of rejects due to undesired flow of the resin liner 14 during molding has been greatly reduced.
