Abstract: This invention relates to a mold for the covering and trimming of plastics products, particularly of panels for the inside upholtery of motor vehicles. The object of the invention is to avoid that the covering material (4), spread over a heated sheet of plastics material intended to constitute the product (3) to be covered, may be pinched between two side knives (8) associated with two substantial­ly rectilinear sides of the outline of the product (3) and converging to each other toward a preferably rounded corner of said product (3). To achieve this object, at the angle between the two side knives (8) associated with the con­verging substantially rectilinear sides, ther is arranged a knife (8') which is shaped correspondingly to said corner, and the ends of which slidably engage the outer planar surfaces of tapered end extensions (108) of the side knives (8). Means (9, 9', 10, 10') are provided for displacing simultaneously the side knives (8) and interposed shaped knife (8'). The sliding surfaces between the extensions (108) of the side knives (8) and interposed shaped knife (8') are at such an angle to the directions of movement of either the two side knives (8) and the interposed shaped knife (8') as to always remain in contact with each other during the movement of said knives.

Abstract: Disclosed is a process for the continuous preparation of high internal phase emulsions which are suitable for subsequent polymerization into polymeric foam materials that, upon dewatering, act as absorbents for aqueous body fluids. The process involves continuous introduction of a certain type of monomer-containing oil phase and a certain type of electrolyte-containing water phase into a dynamic mixing zone at relatively low water to oil phase ratios. Flow rates are then steadily adjusted to increase the water to oil ratio of the streams fed to the dynamic mixing zone while subjecting the dynamic mixing zone contents to shear agitation which is sufficient to thereby form a high internal phase emulsion that, upon subsequent polymerization, provides a foam having an average cell size of from about 5 to 100 microns. The formation of such a stable high internal phase emulsion is completed by feeding the contents of the dynamic mixing zone to and through a static mixing zone.
